Abstract:

There are many direct and indirect methods of measuring the volumetric ratioof red blood cells relative to sample size and total blood, but the manual carcinogenic method remains the most stable and least expensive method despite the possibility of human error.The ratio percent of the packed red blood cell volume to the total volume of the blood sample is known as the packed cell volume (PCV). Our efforts were directed at finding a precise and economic method for PCV determination. There by, we designed a simple device consisting of a digital camera that is connected to a computer which uses a specific MATLAB program to process the blood images. As a result,the image can be read and the PCV can be calculated using a special code system. This new measuring system provides the capabilities and advantagesto frequently comment on measured PCV with normal or abnormal, in comparison with normal values of PCV, which are stored in the computer. Our measurement method provides accurate results compared to the ruler results to alleviate the effort of clearing the hepatitis C virus from the blood (PCV). This system enables a swift and simple sample analysis and PCV identification.

Abstract:

Malaria parasites and packed cell volume offree range poultry was conducted on one hundred free range chickens collected from three communities in Abeokuta (Osiele, Lafenwa and Kuto). The results revealed that out of the 100 free range chickens examined, 13(13%) were infected with avian malaria parasite. Hematological parameter i.e. packed cell volume (PCV) revealed that chicken with PCV range 16-20 were 33.33% positive for malaria parasite. Others between PCV ranges 21 – 25 were 33.3%, while those between PCV ranges of 26 – 30 were 16.66% and those with PCV range of 31 – 35 were 16.67%.Chi-square analysis showed a significant difference between packed cell volume and malaria parasite(p<0.05). However, no significant difference was observed between sex and malaria parasite(p>0.05). The presence of avian malaria parasites in the study area could be of some epidemiological implications since the infected poultry could act as reservoir for malaria parasites.

Abstract:

ABSTRACT Packed cell volume (PCV) is commonly used to assess and monitor red blood cell count in animals, but the results can be altered if inappropriate ratios of anticoagulant/blood are used. The purpose of this study was to determine the effect of ideally filled, overfilled, and underfilled K3 ethylenediaminetetraacetic acid (EDTA) tubes with various volumes of healthy dog blood on centrifuged PCV. Six milliliters of blood was obtained from 94 blood donors each. Initial distribution was injected into two nonheparinized microhematocrit tubes. The remainder was instilled into 1.3 mL K3 EDTA spray-dried tubes as 1.5 mL, 1.3 mL, 0.75 mL, 0.5 mL, and 0.25 mL aliquots. Normality was determined using the D’agostino–Pearson method and by visual examination of histograms. Data were analyzed using a repeated-measures analysis of variance with post hoc testing using Tukey’s test. There is a statistically significant decrease in the PCV between all groups with progressive underfilling of tubes (P < .0001). The closest difference is between 1.5 and 1.3 mL (P = .0138). Our study suggested that underfilling K3 EDTA tubes significantly and negatively influences the PCV in healthy dogs. Using underfilled K3 EDTA tubes result in a lower PCV compared with directly filled microhematocrit tubes without anticoagulant.

Abstract:

Red blood cell (RBC) transfusions in 307 dogs were reviewed. A total of 658 units of RBCs, including 474 (72%) units of packed red blood cells (PRBCs) and 184 (28%) units of whole blood (WB), were administered. Reasons for transfusion included hemorrhage (n = 222), hemolysis (n = 43), and ineffective erythropoiesis (n = 42). The mean pretransfusion packed cell volume (PCV) of dogs with hemolysis (13%) was significantly lower (p less than 0.0001) than the mean pretransfusion PCVs of dogs with hemorrhage (21%) or ineffective erythropoiesis (18%). The mean total volume of PRBCs transfused was significantly greater (p less than 0.03) in dogs with hemolysis. Overall, 187 (61%) of 307 dogs were discharged from the hospital. Cause of anemia, pretransfusion PCV, and total volume of blood administered did not appear to influence survival. However, the mean adjusted posttransfusion PCV of dogs with hemorrhage was significantly higher (p less than 0.001) in dogs that survived. Possible adverse events were observed during or shortly after RBC transfusion in 10 (3.3%) dogs; all reactions were mild and self-limiting, and none were hemolytic.

Abstract:

ObjectiveTo evaluate whether a standard operating procedure (SOP) for canine packed cell volume (PCV) measurement reduces operator-dependent variation and improves accuracy within a veterinary teaching hospital environment.Materials and methodsClinical staff and final-year undergraduate veterinary students were recruited to perform PCV measurements in blinded duplicate samples. Participants were randomly allocated to perform this with or without an SOP. Participants’ results were compared against a reference, generated by the authors following the World Health Organization guidelines.ResultsThe study population comprised 18 clinical staff and 39 students. Three clinical staff and seven students displayed errors consistent with inaccurate reading, only one of whom had access to the SOP. Five students and two clinical staff had errors attributable to incorrect preparation, with only one having access to the SOP. Interoperator variation was significantly less using the SOP. Using the SOP, 95 per cent of the results were within 0.0125 l/l of the reference value, in comparison with within 0.09 l/l without SOP. Interoperator variation was significantly less in the SOP group (P=0.0025).Clinical significanceUsing the SOP resulted in less variation and more accurate results. This confirms that PCV measurement with an SOP can truly be a ‘waived’ test.

Abstract:

Bovine blood samples with ethylene diamine tetra-acetate (EDTA) or oxalate as anticoagulant were stored at refrigeration temperature of 4°C. The packed cell volume (PCV) was determined daily. During storage, the PCV did not vary significantly. Complete haemolysis, suggested by failure of blood samples to separate into cellular and plasma fractions, started occuring in samples on days 28 and 17, and was observed to have occurred in all samples on days 41 and 24 in blood with EDTA and oxalate respectively.

Abstract:

Anaemia is a common morbidity in the NICU and often requires transfusion of packed red blood cells. Haematocrit equilibration following red cell transfusion occurs over time ultimately resulting in a stable packed cell volume (PCV). Knowledge of this equilibration process is pertinent in the accurate timing of posttransfusion (PT) PCV. We conducted a prospective study to determine an appropriate timing for PT PCV estimation on 47 stable anaemic babies at the Neonatal Unit of National Hospital, Abuja. Values of PCV were determined before transfusion and at 1, 6, 12, 24, and 48 hours posttransfusion. Forty of the recruited neonates and young infants were analyzed. Their gestational age range was 26 to 40 weeks. 1-hour PT PCV (48.5% ± 5.5%) was similar to the 6-hour PT PCV (47.8% ± 5.6%)P=0.516, but both were significantly different from the 12-hour (46.8% ± 5.9%), 24-hour (45.9 ± 5.8%), and 48-hour (45.4% ± 6.2%) PT PCVs. The 12-hour PT PCV was similar to the 24-hour and 48-hour PT PCVs (P=0.237and 0.063, resp.). We concluded that, in stable nonhaemorrhaging and nonhaemolysing young infants, the estimated timing of haematocrit equilibration and, consequently, posttransfusion PCV is 12 hours after red blood cell transfusion.

Abstract:

Monitoring packed cell volume (PCV) is essential to safeguard oxygen delivery to the tissues during cardiopulmonary bypass (CPB). We compared the results obtained using a PCV monitor, a blood gas analyser and a microcentrifuge with those from a laboratory-based automated blood cell counter. PCV was measured in 221 samples of 40 patients undergoing open-heart surgery. The limits of agreement (mean difference ± 2 SD) was unacceptably wide when the results obtained with the PCV monitor and the blood gas analyser were compared with those of the automated blood cell counter. This was most pronounced when PCV was measured in low concentration samples. The microcentrifuge showed good limits of agreement regardless of sample concentration. The data suggests that measurement of PCV by either continuous monitoring or by a blood gas analyser is not an accurate alternative to an established laboratory method. The microcentrifuge is the most accurate method of the ones investigated to measure haematocrit during CPB.

Abstract:

Erythrocyte (RBC) count, packed cell volume (PCV) and haemoglobin (Hb) values were found to be higher in Nigerian domestic fowls than those in Hubbard fowls. PCV and Hb values were higher in males than in females in both breeds. Erythrocytes of the Nigerian fowl were observed to be more susceptible to osmotic haemolysis than were erythrocytes of the Hubbard fowl. Erythrocytes of male fowls were osmotically more fragile than were those of female fowls in both breeds.

Abstract:

Anaemia is a common finding in South American camelids presented to the veterinary clinic. This report describes the case of a llama presented with general weakness and pale conjunctives, displaying severe anaemia with a Packed Cell Volume (PCV) of 6 per cent and suffering from haemonchosis. The animal was presented in lateral recumbency before being treated with whole blood transfusion. After administering a total volume of 850-ml blood, the clinical condition improved remarkably. Regeneration of the haematological parameters required several weeks, PCV increased from 6 per cent on day 0 to 23 per cent on day 28.

Abstract:

Background: During pregnancy the women undergo several structural and physiological changes almost in all body systems including the hematological profile. The main reported hematological change is the plasma expansion and haemodilution which affect the red blood cells(RBCs) and white blood cells (WBCs) count in addition to other hematological indices including packed cell volume (PCV). The objective of this study was to assess the effect of pregnancy on packed cell volume and white blood cells among Sudanese pregnant women and derive a formula for the normal values in pregnant women in relation to the packed cell volume.Methods: An analytical case control study was conducted in Khartoum state, Sudan 2017. The study included20 Sudanese pregnant women in the second and third trimesters attending the antenatal care at The National Ribat university hospital and 20 Sudanese non-pregnant women in the same age group as control. A questionnaire was used to collect socio-demographic and clinical data.5ml of venous blood was collected in a container containing EDTA. Complete blood count (CBC) was measured by using automated cell counter Sysmex.Results: There was statistically significant decrease in PCV value during 2nd and 3rd trimesters of pregnancy compared to the non-pregnant control group with p values (0.00 and 0.04 respectively), and statistically significant increase in WBCs count during 2nd and 3rd trimesters of pregnancy compared to the non-pregnant control group with p values (0.04 and 0.00 respectively). Also, a progressive increase in WBCs count with gestational age was demonstrated (second trimester 6.65×103/uL, third trimester 7.43×103/uL). The results showed mean WBCs of 7.79×103/uL, when compared to the estimated values the results showed no significant difference with the mean WBCs in 2ndand 3rdtrimesters (p value 0.06 and 0.39 respectively).Conclusions: During pregnancy there was statistically significant decrease in PCV values, statistically significant increase in WBCs count and by considering the haemodilution factor there was a higher increase in WBCs count.

Abstract:

Sixty seven healthy growing goat kids of three Omani breeds, born and raised in Sultan Qaboos University Agricultural Experiment Station, were used to study the effects of age, breed and sex on haematological parameters. Blood samples were collected at several times from the first to 25 weeks to study the following parameters: Red Blood Cells (RBCs), White Blood Cells (WBCs), Packed Cell Volume (PCV), Haemoglobin (Hb), Mean Cell Volume (MCV), Mean Cell Haemoglobin Concentration (MCHC) and Mean Cell Haemoglobin (MCH). At birth, MCV and MCH levels were significantly higher in Batina (BAT) kids than both Jabal Akhdar (JA) and Dhofari (DOF), but there were no breed differences in the rest of the haematological values. There were significant breed differences in RBC, MCH, WBC, MCV at different ages, with Hb and PCV being highly significant at all ages. All blood parameters changed with time but showed different patterns in all breeds. There was no effect of sex on RBC, MCHC, PCV, Hb or WBC, but female kids had significantly higher MCH and MCV values at week 12. This study indicates that haematology parameters in Omani goat kids could be affected by age, breed and sex.

Abstract:

1. Blood rheology has been quantified by measuring blood and plasma viscosity, packed cell volume (PCV), erythrocyte filterability and erythrocyte aggregation in forty-eight voluntary vegetarians and compared with matched controls.2. Results show that in vegetarians, values for PCV were lower than those in controls, leading to reduced native blood viscosity. In addition PCV-standardized blood viscosity was also decreased. This was brought about mostly by lower plasma viscosity. Erythrocyte rheology seemed to be unaltered. Stricter avoidance of animal products was associated with even lower values for these indices.3. These observations are in agreement with the fact that other low-cardiovascular-risk groups show better than average blood fluidity. They are consistent with the hypothesis that in vitro measurements of blood rheology may provide signs of early atherosclerotic changes in vivo.

Abstract:

Under conditions of oxidative stress, erythrocytes of goats could be predisposed to haemolysis. This study was aimed at evaluating the effect of oxidant exposure to goat erythrocytes using an in vitro model. Blood samples from 10 goats were incubated with 0.06 – 0.18 mM hydrogen peroxide (H2O2) either singly or in combination with 0.02 µM dexamethasone for 60 min, and erythrocyte parameters such as packed cell volume (PCV), red blood cell count (RBC), mean corpuscular volume (MCV) and percentage haemolysis in hypotonic sucrose solution (250 mOsmol/L) were determined thereafter. No significant changes in the mean values of all parameters were observed. The in vitro model indicated that erythrocyte parameters remained stable under low-grade oxidant exposure in goats. Therefore, plasma H2O2 concentration of ≤ 0.18 mM, whether in the presence or absence of 0.02 µM dexamethasone, may not induce apparent oxidative damage in goat erythrocytes that could be estimated by PCV, RBC, MCV and sucrose-based osmotic fragility at low hypotonicity.

Abstract:

Reptiles, especially turtles, are becoming increasingly popular as pets. The haematological evaluation of turtles is an irreplaceable diagnostic tool in veterinary practice. However, the morphologic distinctiveness of turtle blood limits the use of electronic cell-counting devices, making time-consuming, manual counting techniques and evaluation of blood smears necessary. Many samples are dispatched to a laboratory over long distances, where a delay of 24 h or more may occur. At weekends, this interval may exceed 48 h. The objective of the present study was to determine the effect of storage duration at refrigerator temperature (4 °C) on the counts of red blood cells (RBC) and white blood cells (WBC), and on the mean corpuscular volume (MCV) and packed cell volume (PCV) in blood samples from healthy adult red-eared sliders. Blood samples were collected by venipuncture from the occipital venous sinus from six apparently healthy adult red-eared sliders, aged 2 to 4 years. Blood samples were analysed immediately after sampling to obtain the baseline value (BV) of the red blood cell count, white blood cell count and packed cell volume percentage. Blood was stored at 4 °C and the haematological analyses were performed after 24h, 48h and 72h. The results showed the same level of stability for RBC and WBC count, and MCV values during 72 hours of storage at 4 °C and for PCV during 48 hours. Handling of blood samples, and duration of storage of the blood samples can significantly influence the results/values of haematological tests. Consequently, the obtained values of the determined haematological parameters of improperly stored or handled blood samples can give a misleading interpretation of the results on the animal’s health status.

Abstract:

Abstract Fifty-two naturally parasite-infected intact male Spanish goats 6–7 mo of age were used in a 6-wk trial to investigate effects of ‘Serala’ (SER) sericea lespedeza (SL; Lespedeza cuneata) on indicators of gastrointestinal parasitism. Goats were individually housed in 1.5 x 1.5 m pens. Treatments were pure SER (n = 18) or ‘AU-Grazer’ (AUG; n = 16) varieties of SL or bermudagrass hay (n = 18; CON) at 75% of the ration. A corn-soybean meal-based supplement (25% of the ration) ensured isonitrogenous (17% crude protein), isocaloric diets. Diets were fed to 10% orts. Treatments were assigned for similar initial group mean fecal egg count (FEC). At the start of the study (D 0) and weekly thereafter, FEC and coccidia oocyst counts (FOC) were conducted via a modified McMaster’s technique [eggs per gram (epg); oocysts per gram (opg)], and percentage packed red blood cell volume (PCV) was measured via microhematocrit centrifugation. Data were analyzed using a mixed model for repeated measures. There was a treatment by time interaction (P < 0.001) for FEC. In week 1, SER and AUG were lower (P < 0.02) than CON and were higher than control at week 6 (AUG tendency only, P < 0.10; SER, P < 0.02). The FOC were impacted by treatment (P < 0.008), averaging 1977 ± 945 opg for AUG (lowest, P < 0.01), 3558 ± 876 opg for SER and 4164 ± 955 opg for CON (SER and CON similar). Percentage PCV tended (P < 0.09) to be influenced by a treatment by time interaction in which AUG and SER were similar over time, while PCV for CON animals was lower (P < 0.03) than D 0 at all sampling points after the first week. Overall, there was no effect of SER on FEC or FOC and no effect of AUG on FEC, though PCV was maintained throughout the study for both SL treatments.

Abstract:

Transurethral resection of the prostate (TURP) is the gold standard of surgical therapy of benign prostatic hyperplasia (BPH) for prostates <100 ml. This study was carried out to describe our experience with and outcome of staged TURP for large prostates (>100 ml). A review of the records of all the patients who underwent staged TURP for large BPH at a specialist urology center. They had two-stage monopolar resection using a size 26F continuous flow resectoscope and 5% Dextrose water irrigation. Staged-TURP were performed by a single Consultant Urologist under spinal anesthesia. Patients’ age, Co-morbidities, Prostate-specific Antigen (PSA), Abdominal Ultrasound scan (USS) estimated prostate volume, Pre-operative Packed Cell Volume (Pre-op PCV), Post-operative Packed Cell Volume (Post-op PCV), Resection Weight for 1st stage (RW I), Resection Weight for 2nd stage (RW II), Resection Time for 1st stage (RT I), Resection Time for 2nd stage (RT II), blood transfusion were obtained and analyzed. Follow up was for a minimum of 9 months and the outcome and development of complications noted. Statistical analysis was done using the IBM Statistical Package for the Social Sciences (SPSS) version 20.0 (IBM, Chicago, USA). Means and percentages were calculated, and paired sample T test was used to compare variables between 1st stage and 2nd stage. P value < 0.05 was considered significant. Twenty-five patients with a mean age of 72.32±7.98 years were analyzed. Most (88%) were on indwelling Foley’s urethral catheter before surgery. The mean PSA and prostate volume were 25.61±22.08 ng/ml and 221.56±62.78 cm3. There were significant differences between Pre-op PCV and Post-op PCV (p<0.001); RWI and RWII (p<0.001); and RTI and RTII (p<0.001). Nineteen patients (76%) received perioperative transfusion. Most patients voided satisfactorily following catheter removal except one who developed acute urinary retention (AUR). No cases of TUR syndrome, post-operative sepsis, DVT or PE and urethral stricture were recorded. Staged TURP is safe and effective treatment modality for patients with large prostates in the absence of more recent endoscopic options.

Abstract:

Abstract Compact analyzers suited to near-patient testing estimate hematocrit by measuring the conductivity of undiluted blood. We evaluated the accuracy of hematocrit determination of one such analyzer (Instrumentation Laboratory BGE analyzer) against an automated cell counter (EPC) and packed cell volume (PCV) microhematocrit. When specimens (n = 34) from outpatient and ward patients were analyzed with all three methods, the BGE analyzer correlated well with both EPC and PCV hematocrit determinations (BGE = 1.00 PCV + 0.3%, S(y)/x = 2.0%), suggesting that all three methods are similar in performance for most patients. However, a patient with increased plasma osmolality showed significant decreases in BGE and PCV hematocrits relative to the EPC method. The differences in hematocrit measurements could be reproduced by adding solutes to blood in vitro or by modifying the plasma osmolality of rats in vivo. Samples from patients undergoing cardiac surgery, whose blood had large changes in protein concentration, showed discrepancies between hematocrits by conductivity and other methods; similar effects could be produced by changes in protein concentration or in vitro addition of polyethylene glycol. We conclude that conductivity measurements provide accurate hematocrit results for physiologically normal subjects but not for some intensive-care and surgical patients.

Abstract:

Persistence and biochemical characteristics of cypertnethrin and permethrin in the blood of male rats were studied following oral administration of a single dose containing 10 mg.kg -1 of body weight of each pyrethroid. The highest residue concentrations of cypermethrin (2.38 ug.ml-1) and permethrin (8.83 ug.ml-1) in rat blood tissue were detected 24 h after treatment. After two weeks cypermethrin residues decreased to 0.013 ug.ml -1 , whereas permethrin was not detected. Both pyrcthroids decreased the red blood cell (RBC) count, and packed cell volume (PCV) The greatest reduction in RBC count and PCV occurred at 504 h and 336 h respectively. Moreover, the result of post treatment white blood cell (WBC) count was influenced more by permethrin than by cypermethrin, especially after 80 h, 168 h and 504 h of treatment. However, the blood haemoglobin concentration in treated rats was not affected by either pyrethroid.

Abstract:

One hundred and twenty Clarias gariepinus fingerlings (2.33 ± 0.07 g) were fed with 40% crude protein diets containing three concentrations of Aloe barbadensis leaves-paste: ABL1, 1%; ABL2, 2%; ABL3, 3%, and control, 0% ad libitum twice daily for 12 weeks. Mean weight gain and percentage weight gain increased (P < 0.05) as concentration of A. barbadensis increased. Survival rate decreased as concentration of paste increased. Differences (P < 0.05) seen in packed cell volume (PCV), haemoglobin (Hb), and red blood cell (RBC), thus highest in ABL3: PCV (36.67 ± 0.89%), Hb (12.37 ± 0.37 g dl–1) and RBC (3.47 ± 0.08×106 L–1) and lowest in control: PCV (22.0 ± 0.58%), Hb (7.37 ± 0.20 g dl–1) and RBC (2.07 ± 0.06 ×106 L–1). Liver histology of control fish was normal, while fatty degenerations were seen in the treated fish. The histology of fish kidney was normal in all treatments. The study concluded that 1% A. barbadensis leaves-paste could effectively improve growth performance, nutrient utilization and survival of cultured C. gariepinus.

Abstract Pyrethroids, commercially available pesticides, are greatly in use these days, and thus they carry considerable chances of contaminating various ecosystems. Haematotoxicity of cypermethrin, a broadly used type II pyrethroid, has been assessed in the present study. Selected parameters included determination of total RBC count, haemoglobin concentration (Hb conc.), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), erythrocyte sedimentation rate (ESR), total leukocyte count (TLC), differential leukocyte count (DLC), along with qualitative analysis of blood and bone marrow. Of these parameters, those showing significant decline following cypermethrin intoxication included total RBC count, Hb conc., PCV, MCV, MCH, whereas non-significant decrease was observed in the case of MCHC. ESR, TLC and DLC, on the other hand, increased significantly following cypermethrin intoxication. Qualitative changes included altered red cell morphology such as microcystosis, appearance of stomatocytes, poikilocytosis, giant platelet formation, etc. in peripheral blood and increased erythroid precursors in bone marrow of treated rats. These parameters were however normalised following twenty-two days of recovery phase

Abstract:

We studied the hematology and blood chemistry of 33 adult bobcats (Felis rufus) captured from 1982 through 1985 in southeastern Idaho during a decline in lagomorphs, their major prey. Our objectives were to relate blood physiology of bobcats to sex, season, and a decline in abundance of black-tailed jackrabbits (Lepus californicus) and Nuttall's cottontail rabbits (Sylvilagus nuttallii). Males had higher (P < 0.10) erythrocyte counts (RBC) and hemoglobin levels (Hb) and lower (P < 0.10) insulin concentrations than females. Bobcats sampled during spring had higher (P < 0.10) mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and'insulin levels, and lower (P < 0.10) Hb, packed cell volume (PCV), RBC, and cholesterol levels than bobcats captured in autumn. The decline in lagomorph prey abundance from 1982 to 1983 was reflected in bobcat blood by lower (P < 0.10) phosphorus and insulin levels and higher (P < 0.10) Hb, RBC, and PCV. Progesterone levels in females reflected field results indicating that reproduction was curtailed when prey was scarce.

AbstractBackgroundHematological parameters are vital diagnostic tools for understanding health dynamics of humans and animals. Franquet’s fruit bat (Epomops franqueti) is host to several parasites such as protozoa, bacteria, viruses and mites. Yet, studies exploring the values of its blood components with interest for research or food purposes are scarce. Thus, this study was carried out to investigate the hematological values of the adultE. franqueti.MethodsSeventeen (nine female and eight male) apparently healthy adultE. franquetiwere captured from their roosting colony. Blood samples were collected for determination of erythrocyte indices [red blood cell count (RBC), packed cell volume (PCV), hemoglobin (Hb) concentration, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC)] and leukocyte indices [total white blood cell counts (WBC), lymphocytes, eosinophil, monocytes, neutrophil count and erythrocytes osmotic fragility].ResultsThere were no significant (p≥0.05) sex-related differences in RBC, PCV, Hb concentration, MCV, MCH, MCHC and total and differential WBC ofE. franqueti. Erythrocyte osmotic fragility was significantly higher in female than in maleE. franquetiat 0.1% NaCl.ConclusionsThese considerations are critical in establishing reference ranges of blood parameters forE. franquetiand may provide insight to why they serve as reservoir hosts for several microorganisms.

Abstract:

An epidemiological survey of haemoparasitic infection in trade cattle was carried out at Lafenwa abattoir, Abeokuta, from August to November 2008. Thin Blood film and Haematocrit Centrifugation Techniques were used to detect haemoparasites. A total of 452 cattle that comprised 174 cows and 278 bulls were examined. The breeds included 78 'Red Bororo', 14 'Sokoto Gudali' and 360 'White Fulani'. Packed cell volume (PCV), red blood cell (RBC) count, haemoglobin concentration (Hb), total white blood cell (WBC) count and differential counts of WBC, mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) were measured. Data were subjected to analysis of variance using Genstat statistical software, with sex and breed and blood parasite species detected as factors. Results showed that 22% of the cattle were infected with haemoparasites while 78% were parasite-free. The parasites were Trypanosoma congolence (4%), Anaplasma central (2%), Babesia bovis (14%), A. centrale + B. bovis (1%) and Babesia divergens (1%). Parasite species identified significantly influenced (P < 0.001) the PCV, RBC, and Hb concentration. The prevalence rates observed is considered to be of epidemiological and economic importance because infected animals might be sources of infection to other healthy herds in the area.

Four groups of six Holstein calves were inoculated with 3.6 × 10(7) erythrocytes parasitized with Anaplasma marginale. The criteria for treatment of calves were increasing A. marginale rickettsemia and 30% reduction of baseline packed cell volume (PCV) of each animal. Group 1 (G1) received 7.5 mg.kg-1 of enrofloxacin in a single dose; Group 2 (G2) 7.5 mg.kg-1 of enrofloxacin twice every three days; Group 3 (G3) 20 mg.kg-1 of long-acting oxytetracycline in a single dose; and Group 4 (G4) a single dose of PBS. Physical examinations, blood smears and PCV were performed daily. On day treatment, G1, G2 and G3 animals had a mean rickettsemia of 17, 23 and 12%, respectively. At 2 days after treatment (DAT) G1 and G2 animals showed a significant reduction of rickettsemia (p < 0.05) compared to G3. G3 animals had high rates of rickettsemia in the first 2 DAT and a slow decrease until stabilization on 9 DAT. The mean PCV in G1 and G2 increased and stabilized after 7 and 8 DAT, respectively. PCV stabilization was achieved in G3 at 13 DAT. Both enrofloxacin and oxytetracycline were effective for the treatment of anaplasmosis, but enrofloxacin was faster reduction of rickettsemia and PCV recuperation (p < 0.05) compared to oxytetracycline

Full text

Abstract:

Hematocrit (packed cell volume, PCV) varies seasonally in some vertebrates and often differs between the sexes and among conspecific populations. Such variation in PCV may reflect variation in nutritional health, requirements for oxygen transport (metabolic rate), or hydration. The relative importance of these influences was tested with serial measurements of PCV in two Mojave Desert populations of the desert tortoise (Gopherus agassizii) over two activity seasons, during a period with large seasonal differences in availability of food and water. Hematocrit varied widely (range = 1440, CV = 20%), reflecting differences between populations, between sexes, between years, and over time within years. Causal hypotheses were tested by correlating PCV with physiological indicators of nutritional health (blood urea nitrogen), oxygen requirements (field metabolic rate), and hydration (length-relative mass, water-influx rate, urine osmolality, plasma sodium, and plasma osmolality). Results indicated a dominant influence of dehydration-induced hemoconcentration during this extreme drought period, although all correlations were relatively weak. Circumstantial evidence is marshalled to suggest longer term effects of nutrition (at seasonal, yearly, and population levels of variation) and perhaps oxygen requirements (driving sexual dimorphism). All these simultaneous and sometimes opposing effects interact in complex ways to produce the patterns of variation observed, and these interactions render PCV a poor indicator of physiological state in desert tortoises.

The toxic effects of the leaves of Eugenia uniflora Linn on rats was evaluated by observing abnormal changes in the haemogram including erythron and leukogram, serum biochemical parameters, histopathology, and hexobarbital sleeping time. The leaf extract produced significant increases in the packed cell volume (PCV) haemoglobin concentration and total red blood cell counts (P.05) but did not influence the blood coagulation time. Similarly the leaf extract of Eugenia uniflora produced significant increases (P.05) in the serum activities of alanine aminotransferase and aspartate aminotrasferase. Although the extract did not produce histological lesions of the liver, the increases in liver enzyme activities could be due to incipient liver damage.

Abstract:

Abstract Gum arabica (GA) is a well-known traditional herbal medication from Acacia Senegal. Previous studies have shown that GA has physiological and therapeutic effects on animals. Anemia is a reduction below normal in the number of red blood cells. Infection by parasites, such as Haemonchus contortus, can result in anemia when there is a reduction below normal in the number of red blood cells. The objective of this study was to evaluate the effect of GA on anemia in goats. The packed cell volume (PCV) and FAMACHA© score were used as indicators of anemia. Clinically healthy Boer and Spanish goats (n = 20) from the NCA&T University Farm Small Ruminant Unit were used in the study. Following initial screening for infection, twenty goats (n = 20) were assigned randomly to two groups of ten (n = 20). Goats in the treatment group were drenched daily with 10 mL of GA extract for 6 weeks. A control group of ten age-matched goats received sterile water. The FAMACHA© score was evaluated and recorded weekly. Blood samples collected at the time of evaluation were assessed for packed cell volume weekly. Data were analyzed by using PROC GLM in SAS 9.4(PM < 0.05). Treatment with GA increased PCV and decreased FAMACHA© scores when compared to the control group. Thus, water extracts of GA may aid in alleviating anemia, caused by parasites or resulting from other causes, to enhance goat health and production. The effect on parasites and overall health is being evaluated.

Abstract:

Information on the spatial pattern of African animal trypanosomosis forms a prerequisite for rational disease management, but few data exist for any country in the continent. The present study describes a raster or grid-based Geographic Information System for Togo, a country representative of subhumid West Africa, with data layers on tsetse, trypanosomosis, animal production, agriculture and land use. The paper shows how trypanosomosis prevalence and packed cell volume (PCV) map displays may be predicted from correlations between representative field data and environmental and satellite data acquired from the National Oceanographic and Atmospheric Administration (NOAA) and Meteosat platforms. Discriminant analytical methods were used to assess the relationship between the amount of field data used and the accuracy of the predictions obtained. The accuracy of satellite derived predictions decreases from tsetse abundance to trypanosomosis prevalence to PCV value. The predictions improve when eco-climatic and epidemiological predictors are combined. In Togo, and probably elsewhere, the patterns of trypanosomosis prevalence and PCV are much influenced by animal husbandry and other anthropogenic factors. Additional predictor variables, incorporating these influences might therefore further improve the models.

Abstract:

Transfusion therapy is a major resource that can improve the patient's capability to overcome the underlying disease. However, the effects of whole blood infusion, and how they affect the patient's outcome, are not yet clear. For this study, a protocol was developed in order to monitor a group of 15 animals (9 dogs, 6 cats) that received a total of 19 transfusions; 3 animals received more than one transfusion each. The most common indications for blood transfusion included acute blood loss (47%), coagulopathy (33%) and other anaemias (20%). The mean pre-transfusion packed cell volume (PCV) of animals with acute blood loss (18%) was higher than in the group of coagulopathy (15%) or other anaemias (15%). The survival rates at 6 days after transfusion were greater in the coagulopathy (80.0%) and other anaemias (66.7%) than in the group of acute blood loss (42.9%). After transfusion, pulse rate ( p <0.01) and platelet count ( p <0.05) decreased significantly, and there was a significant increase in body temperature of the animals that suffered from hypothermia before the transfusion ( p <0.05). Overall survival was predictable based upon posttransfusion body temperature, observed PCV change, the difference between the obtained and the calculated PCV, and administered transfusion volume ( p <0.05)

Abstract:

Background: HemoSep® is a commercial ultrafiltration and haemoconcentration device for the concentration of residual bypass blood following surgery. This technology is capable of reducing blood loss in cardiac and other types of “clean site” procedures, including paediatric surgery. Clinical feedback suggested that the device would be enhanced by including a sensor technology capable of discerning the concentration level of the processed blood product. We sought to develop a novel sensor that can, using light absorption, give an accurate estimate of packed cell volume (PCV). Materials and methods: A sensor-housing unit was 3D printed and the factors influencing the sensor’s effectiveness – supply voltage, sensitivity and emitter intensity - were optimised. We developed a smart system, using comparator circuitry capable of visually informing the user when adequate PCV levels (⩾35%) are attained by HemoSep® blood processing, which ultimately indicates that the blood is ready for autotransfusion. Results: Our data demonstrated that the device was capable of identifying blood concentration at and beyond the 35% PCV level. The device was found to be 100% accurate at identifying concentration levels of 35% from a starting level of 20%. Discussion: The sensory capability was integrated into HemoSep’s® current device and is designed to enhance the user’s clinical experience and to optimise the benefits of HemoSep® therapy. The present study focused on laboratory studies using bovine blood. Further studies are now planned in the clinical setting to confirm the efficacy of the device.

Abstract:

Animal welfare for sheep in extensive rural farms is difficult to quantify among rural farmers due to several factors, including the lack of technology and the low level of interaction they have with the animals. The purpose of this study was to search for animal-based iceberg indicators using the Five Domains Model approach and study the relationship between sheep reactive behavior (flight distance), sheep handling training and farmers job satisfaction. Thirteen extensive commercial dual-purpose sheep farms (n = 520 animals) were evaluated in Marulanda, Caldas (Colombia, South America). On-farm Animal Welfare Indicators (AWIN) were assessed using an adapted version of this protocol. Socio-demographic characteristics, sheep handling training and job satisfaction were evaluated using a structured interview. Blood and stool samples were taken to determine Fecal Egg Count and Packed Cell Volume. Bivariate regression models were used to find animal-based indicators that predicted Nutrition, Ambience, Health and Behavior welfare domains, and a Qualitative Behavior Analysis was used for mind state domain analysis. Body condition score (BCS) (p = 0.001), fleece cleanliness (p = 0.03), FAMACHA© Score (p = 0.05), and flight distance in meters (p = 0.19) were found to be indicators, and were useful for predicting overall welfare assessment (R2 = 0.85) on theses farms. Regarding mind welfare domain, Qualitative Behavioral Assessment found two principal components (PC) that explained 82% and 67% of the variance, and described emotional valence and energy levels of sheep, respectively. Sheep handling training (β = −8.75, p = 0.004) and job satisfaction (β = −7.5, p = 0.013) had a negative association with the average flock flight distance. Spearman’s rank correlations were significant (p < 0.001) between Fecal Egg Count, Packed Cell Volume, FAMACHA© Score (FS), Body Weight (BW) and, BCS. The strongest association was observed between Packed Cell Volume (PCV) and Fecal Egg Count (FEC) (r = −0.43), also FS was correlated with PCV (r = −0.28) and FEC (r = 0.21), and BCS was correlated with weight (r = 0.32). We suggest that these animal-based indicators could be useful as iceberg indicators for extensive sheep production systems and may set the ground for more research in small extensive sheep farms to develop strategies to find welfare problems and solutions.

Abstract:

This study was conducted to evaluate and describe presenting clinical signs, course, management, and outcome of small animal patients that suffered severe traumatic hemoperitoneum. The medical records of 28 blunt trauma patients diagnosed as having hemoperitoneum and requiring the transfusion of blood products for stabilization were analyzed. The survival rate was 16/28 (57%). Six patients died from natural causes, and six patients were euthanized. Euthanized patients were not considered for the analysis of outcome. The survival rates for six animals that had surgical intervention and 16 animals that were treated medically were 67% and 75%, respectively. Statistically, larger animals had a better prognosis (p less than 0.05, unpaired t-test) for survival. Presenting clinical signs, packed cell volume (PCV), peripheral pulse rate, effusion PCV, site of intra-abdominal hemorrhage, and age were not found to correlate statistically with survival nor with the decision to perform an abdominal exploratory.

Abstract:

The dynamic of natural infections by Anaplasma marginale in calves was evaluated during a period of one year on two farms located in the Metalúrgica Region, State of Minas Gerais, Brazil. Blood samples were collected weekly for rickettsemia and packed cell volume (PCV) determination. The animals born from March to July suffered the infection in October and November, independently of their age, whilst calves born from September to December acquired the infection during the first days of life. These animals presented patent rickettsemia from 30 days of life. During the patent period PCV decreased after one week of infection, ranging from 20 to 23%. It was concluded, that in the region studied, the transmission of A. marginale is influenced by climatic conditions, and that calves born during the dry season are more likely to acquire the infection when they are exposed to high transmission levels during the subsequent raining season.
