<strong>The aim.</strong> To substantiate the safety using of the new nasal spray with Enisamium Iodide via study results of acute local drug-induced irritant action of the test object single-dose to eyes and nasal cavity mucosa. <strong>Material and methods.</strong> Enisamium Iodide 10 mg/mL (nasal spray) was the test object. The reference drug was 0.9 % saline. Flemish Giant rabbits were used to induce the experiment (2 groups, 9 rabbits in each group). All study objects were administered in single-dose into the eye conjunctival sacs (0.01 mL) and nasal passages (0.1 mL) by instillation. The eye examination we performed in different time observation point (through 1, 24, 48 and 72 h after drug instillation). Nasal endoscopy was used for control of nasal cavity in all stages of study (15 minutes before, 1-hour and 24 hours after drug instillation) under general anesthesia. The scales of the assessment were used to the result objectivity. <strong>Results.</strong> The total score was 0 points in all groups at all-time points according to the relevant scale and the scale of the assessment of rabbit nasal cavity mucosa by nasal endoscopy results. This corresponds to the condition of a healthy eye and healthy nasal mucosa. <strong>Conclusions. </strong>Enisamium Iodide 10 mg/mL (nasal spray) in the single-dose instillation into the rabbit eye conjunctival sacs and rabbit nasal passages did not show local drug-induced irritant action on the eye conjunctiva and nasal cavity mucosa in the experimental animals. Nasal endoscopy could be used as an informative visual method in preclinical studies

The purpose of the work is a determination of toxicity and sensitizing effects of a new external preparation ‘Ointment for wounds’, based on the essential oils of Siberian pine, eucalypt, tea-tree, cedar, clove, and oil solution of chlorophyllite. The experimental study was performed on rats weighing 160–190 g, 2–3 months of age and mice weighing 18–21 g, 3 months of age. At the stages of preclinical study, it was determined acute and subacute effects of the drug, when administrated on the skin and directly into the stomach of experimental animals. The skin-irritant effect of the phytopreparation was investigated when applied to the skin and buccal mucous membrane. The sensitizing effect of the ointment was evaluated by reproducing local reactions. The acute toxicity assessment was performed on the survival rate of laboratory animals after oral administration of the preparation at doses from 5,000 to 25,000 mg/kg of body weight, with 5,000 units increments. Subacute toxicity in the experiment was evaluated by the dynamics of morphological and biochemical parameters of blood and the study of the coefficients of laboratory animals’ internal organs mass. It was found that the introduction of the drug ‘Ointment for wounds’ in the stomach did not cause significant changes in the behavior of rats, all animals remained alive. Studies have shown the absence of skin-irritant effect of the preparation, as well as the absence of irritant effect on the buccal mucous membrane. Even in a long-term experiment to study subacute toxicity when applied to the skin, no toxic effects of the preparation on the basis of essential oils and oil solution chlorophyllite of were found. The index sensitizing effect of the preparation was less than one, indicating the absence of sensitizing effect. According to the classification of substances by toxicity and danger (requirements of SOU 85.2-37-736:2011 and GOST 12.1.007-76) belong to hazard class IV. In general, ‘Ointment for wounds’ does not have a toxic effect on the functions of vital organs, and at repeated administration is almost harmless

Drugs that have antimicrobial, anti-inflammatory and wound-healing effects deserve special attention, sodium-containing drugs are one of them, which is why they are used in veterinary medicine.
 The article presents the results of experimental studies to study the sub-acute toxicity of sodium-containing drugs: known – glycetinate 2%, its analogues – ovocid 2%, ovocid 3%, potassium-sodium 1.5% (Na / K, 1.5%).
 The study of sub-acute toxicity of drugs was carried out by applying drugs to the skin of animals. The experiment used white rats weighing 250-270 g. 4 groups of rats with 3 animals in each were formed: rats of group I on the skin was applied ovocid 3%, group 2 - Na / K drug 1.5%, 3rd group – ovocide 2%, and the 4th group of rats (control) was applied glycetinate 2%. The animals were subjected to clinical observations, assessing their general condition and skin reaction. The effect of drugs on morphological and biochemical parameters of blood of rats was studied.
 Evaluating the general condition, behavior, local skin reaction of rats for the study of subacute toxicity, local irritant action of sodium-containing drugs, it was noted that they did not cause visible violations of physiological functions, the appearance of clinical signs of intoxication. No significant clinical signs of inflammation or irritation (erythema, edema, and cracks) were recorded on the skin of the animals. At the same time, it should be noted that the animals of all experimental groups had a slight redness at the place of application of the drugs, which later disappeared.

Full textAbstract:
A new derivative of dimethylaminoethanol, butanedioic and trans-butenedioic acids (laboratory code ADK-17) was synthesized at the Department of Organic Chemistry (Professor I.P. Yakovlev is the Head of the Department) of St. Petersburg State Chemical and Pharmaceutical University (SPCPU). This is a promising compound planned for use as an oral dosage form. In this work, we aim to evaluate manifestations of the general and specific toxicity of the new drug. Laboratory animals (white mice, rats, rabbits, guinea pigs) were used as test systems for the preclinical safety study of the new compound. Manifestations of general toxicity (acute and chronic), local irritant action, allergenic properties, immunotoxic action were studied. The reproductive toxicity of the ADK-17 drug when administered intragastrically was studied. The studied drug was found to exhibit low toxicity, cause no changes in the biochemical and morphological parameters of rats and rabbits under the conditions of course use, and have no negative effects on internal organs. When administered intragastrically in maximum doses, the drug causes no irritating effects. The use of the drug did not lead to the development of a local allergic reaction of an immediate type. Carrying out sensitization in the DTH reaction showed the absence of a sensitizing effect. The study of the immunotoxic effect of the ADK-17 drug showed that its prolonged intragastric administration for 30 days at doses of 93 and 930 mg/kg did not lead to a violation of the humoral immune response and a decrease in antibody production. Setting a delayed-type hypersensitivity reaction also confirms that the drug does not affect the development of cellular immunity. The conducted experimental studies of the drug’s reproductive toxicity in rats showed that its repeated intragastric administration at doses of 50 and 250 mg/kg to pregnant females did not have a negative effect on the reproductive system of laboratory animals, embryo- and fetotoxic, as well as teratogenic effects, having no effect on the antenatal and postnatal development of offspring.

Full textAbstract:
Quetiapine is a psychotropic drug, a dibenzothiazepine derivative and a representative of the class of neuroleptics (antipsychotic drugs) of a new subgroup – atypical antipsychotic drugs («second-generation antipsychotics»). Quetiapine fumarate belongs to the 3rd hazard class in terms of DL50 when administered in the stomach according to GOST 12.1.007-76 (DL50 1380-1680 mg/kg, mice and rats), has a local irritant effect: pronounced - on the mucous membrane of the eyes and moderately pronounced - on the skin. There are no signs of skin resorptive or cumulative effects of quetiapine fumarate. When inhaled, an aerosol of quetiapine fumarate has a general toxic and irritating effect in rats. The threshold of acute inhalation action of quetiapine fumarate is set at 6,2 mg/m3 for general toxic effect (effect on the quantitative composition of peripheral blood and the cardiovascular system) and irritating effect on the mucous membranes of the upper respiratory tract. For quetiapine fumarate, the tentative safe exposure level in the air of the working area is recommended at 0,2 mg/m3 , aerosol, with «+» - special protection of the skin and eyes is required. The tentative safe exposure level in the atmospheric air of urban and rural settlements is 0,002 mg/m3.

The drugs, their active ingredients under conditions of manufacture and pharmaceutical waste at the ingress in the environment can be hazardous to the human health. The toxicological examination enables to predict the risk of their adverse effects on the organism with a determination of the prior criteria of hazard. Objectives: We defined the probable toxic effects and the mechanism of their formation under various conditions of the exposure of the original anti-diabetic drug based on a camphoric acid derivative (Diacamph - DCMPh) under various conditions of its exposure. Methods: The peculiarities of DCMPh effect on the organism were studied in the acute, sub-acute, and chronic experiments under different conditions of the drug introduction to animals by the indicators characterizing a state of the organism in a whole and the separate organs and systems of the organism and individual organs and systems, including prooxidant- antioxidant and immune systems. Its possible allergenic and mutagenic effects were studied in a separate run of the experiments. Results: Our studies showed that DCMPh is virtually non-toxic in terms of an acute toxicity, does not accumulate, has no local irritant, mutagenic and allergenic effects, but is capable of the skin resorption. Adverse effect of DCMPh on the organism under its oral and inhalation introduction are realized through the disturbance of the prooxidant-antioxidant balance and cellular components of the immunological resistance. We determined a high sensitivity of lungs to the inhalation impact of DCMPh, taking into account an increase of the free radical oxidation in the organ tissue on the background of the weakening of the antioxidant system and a decrease of the functional reserve of neutrophils manifested in the aftereffect period. The high sensitivity of the lungs to the inhalation effect of DCMPh was determined taking into account the increase in free radical oxidation in the organ tissue on the background of the weakening of the antioxidant system and the decrease in the functional reserve of neutrophils, which manifests itself during the aftereffect period. Conclusions: Taking into account the mechanism of toxic action, the maximum permissible concentration of DCMPh in the air of the working area was substantiated at the level of 0.4 mg / m3, hazard class II.

The article presents the results of two series of experiments on studying the local irritant and anti-inflammatory action of a new complex ointment Uberosept. The studies of the anti-inflammatory activity of the drug were carried out on white rats using the zymosan-induced paw edema model. It has been found that the Uberosept ointment possesses pronounced anti-inflammatory properties, that are not inferior to the comparison drug (Hydrocortisone ointment). The experiments to assess the irritant effect of Uberosept were conducted on guinea pigs. The animals were applied the complex ointment at doses of 0.12 and 0.6 g to the skin used as a single dose, and at a dose of 0.12 g for 14 days. Based on the conducted studies, it can be concluded that the ointment Uberosept does not cause an irritant effect on the skin with a single or long-term use.

Full textAbstract:
Sigma-1 antagonism potentiates the antinociceptive effects of opioid drugs, so sigma-1 receptors constitute a biological brake to opioid drug-induced analgesia. The pathophysiological role of this process is unknown. We aimed to investigate whether sigma-1 antagonism reduces inflammatory pain through the disinhibition of the endogenous opioidergic system in mice. The selective sigma-1 antagonists BD-1063 and S1RA abolished mechanical and thermal hyperalgesia in mice with carrageenan-induced acute (3 h) inflammation. Sigma-1–mediated antihyperalgesia was reversed by the opioid antagonists naloxone and naloxone methiodide (a peripherally restricted naloxone analog) and by local administration at the inflamed site of monoclonal antibody 3-E7, which recognizes the pan-opioid sequence Tyr–Gly–Gly–Phe at the N terminus of most endogenous opioid peptides (EOPs). Neutrophils expressed pro-opiomelanocortin, the precursor of β-endorphin (a known EOP), and constituted the majority of the acute immune infiltrate. β-endorphin levels increased in the inflamed paw, and this increase and the antihyperalgesic effects of sigma-1 antagonism were abolished by reducing the neutrophil load with in vivo administration of an anti-Ly6G antibody. The opioid-dependent sigma-1 antihyperalgesic effects were preserved 5 d after carrageenan administration, where macrophages/monocytes were found to express pro-opiomelanocortin and to now constitute the majority of the immune infiltrate. These results suggest that immune cells harboring EOPs are needed for the antihyperalgesic effects of sigma-1 antagonism during inflammation. In conclusion, sigma-1 receptors curtail immune-driven peripheral opioid analgesia, and sigma-1 antagonism produces local opioid analgesia by enhancing the action of EOPs of immune origin, maximizing the analgesic potential of immune cells that naturally accumulate in painful inflamed areas.

Full textAbstract:
The search for rational treatment of diseases of the nasal cavity and paranasal sinuses is due to the high incidence among the world's population. Despite the absolutely clear recommendations that would seem to greatly facilitate the choice and scope of therapy, it is extremely important to have a differentiated approach to each patient, depending on age, concomitant pathology, the nature of the course of the disease, the severity of clinical, primarily pain symptoms, and the presence of rhinogenic complications. Differential diagnosis of viral and bacterial acute rhinosinusitis (ARS) allows to avoid unreasonable prescription of antibiotics in the former case and choose therapy in such a way as to help relieve clinical symptoms, timely cure the disease and prevent complications. A systematic review of the literature was conducted with the analysis of scientific research data on the evaluation of the effectiveness of protargol or silver proteinate in the local treatment of upper respiratory tract diseases. A review of studies shows that silver proteinate has astringent, antiseptic and anti-inflammatory effects. The spectrum of antimicrobial action of silver is much wider than many antibiotics and sulfonamides. At the same time, pathogenic microflora is more sensitive to silver ions than non-pathogenic microflora. The analysis of the works also demonstrates the absence of adverse reactions when using this drug. The obtained data allow us to recommend preparations based on silver proteinate as a complex therapy for acute and chronic diseases of the nasal cavity and nasopharynx. The vasoconstrictive effect of protargol allows it to be used as an alternative to decongestants in order to avoid the development of drug-induced rhinitis and tachyphylaxis. Sialor® is a new, convenient, affordable, longer-shelf-life form of silver proteinate.

Full textAbstract:
Defibrotide was able to prevent the hemodynamic and biochemical alterations caused by acute myocardial ischemia (AMI) induced by coronary occlusion in the cat when infused 3.5 h before and 5 h after left anterior descending coronary artery (LAD) occlusion. In the platelet perfused heart, Defibrotide was a selective stimulator of coronary vascular PGI^ but not of platelet thromboxane formation. The present study was designed both to investigate the effects of Defibrotide injected 30 min after the induction of acute myocardial ischemia (AMI) in the cat and to evaluate the ability of this drug to reduce infarct size. In the first set of experiments a permanent ligature (5 hours) was placed around LAD. ST segment from ECG, mean aortic pressure (MAP), heart rate (HR) and the pressure-heart rate index (PRI) were considered. Plasma and tissue creatine phosphckinase activity (CFK), tissue lactate and ATP were measured by enzymatic kits from Boehringer Biochemia. 30 min after coronary occlusion a loading dose of Defibrotide (32 ng Kg-1 ) was administered i.v. immediately followed by an infusion (32 ng Kg-1 h 4.5 h-1) MAP, HR and PRI were not modified either by AMI or by the infusion of Defibrotide. AMI-ST segment increases were reduced by Defibrotide from 0.5 h after the beginning of the treatment (—49% vs. AMI control) to the and of experiments (-83% vs. AMI control after 5 h occlusion period). Plasma CFK was reduced from 2.5 h after the beginning of the treatment (-29%) till the end of experiments (-52%). Ischemic tissue CFK, lactate and ATP were normalized by Defibrotide. In the second set of experiments the animals were infused with Defibrotide (50 or 200 mg Kg-1 h-1 , i.v.) starting 2 hours before coronary ligature. The infusion was maintained throughout the 5 h occlusion period. The risk and infarct areas were measured by Evans blu and nitroblue tetrazoliun staining. The 51 ± 3% of risk area was infarcted in AMI control cats. Defibrotide at the two tested doses significantly reduced these infarct areas to 42 ± 4% and 34 ± 2% of risk areas respectively. The beneficial effects of Defibrotide observed in AMI could be attributed both to its ability to enhance PGI2 release from vascular walls and to improved local tissue oxygenation and energy supplies. However it could be taken into account a direct cytoprotective action.
