Abstract:

Zusammenfassung. Ethylenglykol ist ein süsslich schmeckender Alkohol (einfachster zweiwertiger Alkohol, Synonym «Glykol»), der in handelsüblichen Frostschutzmitteln und anderen industriellen Lösungen verwendet wird. Ohne adäquate Therapiemassnahmen kann eine Intoxikation mit Ethylenglykol zu einer schweren metabolischen Azidose, zum akuten Nierenversagen und zum Tod führen. Nach gastrointestinaler Resorption findet die Metabolisierung überwiegend hepatisch, unter anderem durch die Alkoholdehydrogenase, statt und resultiert in einer schweren metabolischen Azidose mit Anionenlücke und der Bildung von Kalziumoxalat-Kristallen, die sich in verschiedenen Geweben ablagern können. In der Niere führt dies zur akuten Tubulusnekrose mit potenziell reversiblem Nierenversagen. Therapeutisch entscheidend ist die schnellstmögliche Inhibition der Alkoholdehydrogenase durch Fomepizol oder Ethanol, um die Bildung toxischer Metaboliten zu verhindern. Die Hämodialyse bietet die effektivste Methode der sekundären Dekontamination. Bei frühem Therapiebeginn ist die Prognose günstig.

Abstract:

Zusammenfassung. Vergiftungen mit Ethylenglykol sind selten, jedoch führt bereits eine geringe eingenommene Menge der Substanz zu Toxizität. Die Schlüsselrolle in der Behandlung liegt im raschen Erkennen einer Intoxikation sowie der sofortigen und gezielten Therapie. Differenzialdiagnostisch sollte man bei Patienten mit einer schweren metabolischen Azidose eine Vergiftung mit Ethylenglykol oder Methanol immer ausschliessen. Dies gelingt nicht zuletzt dank der Berechnung der osmolaren Lücke.

Abstract:

Kindervergiftungen sind häufig, verlaufen aber nur selten schwer oder gar tödlich. Die Herausforderung für Ärzte/Ärztinnen ist es, bei der Vielzahl der Kinderintoxikationen die wenigen lebensbedrohlichen rasch zu erfassen und den Kindern unverzüglich die entsprechende Therapie zukommen zu lassen. Unter den Haushaltprodukten sind Detergentien, Alkohole (Ethanol, Isopropylalkohol), Kohlenwasserstoffe, sowie leicht ätzende Substanzen weit verbreitet. Seltene, aber gefährliche Inhaltstoffe können “toxische Alkohole“ (Ethylenglykol, Methanol), sowie starke Säuren und Laugen sein. Auch bei Vergiftungsunfällen mit Knopfbatterien und Magneten gilt es, die vielen unproblematischen Fälle von den seltenen mit Gefährdungspotenzial abzugrenzen.

Abstract:

Oxalat ist ein schwer wasserlösliches Stoffwechselprodukt, das durch die Nieren ausgeschieden wird. Störungen des Oxalatstoffwechsels treten in Form von intestinaler Hyperoxalurie (sekundär infolge Malabsorption, Magen-Bypass oder bei ungenügender Oxalobacter-Kolonisation), hereditärer Hyperoxalurie und als Intoxikationen (Ethylenglykol, Vitamin C) auf. Hyperoxalurie verursacht ein breites Spektrum von Krankheiten von isolierter Hyperoxalurie bis zu Nierensteinen und Nephrokalzinosebildung, was schliesslich zu Nierenversagen und systemischer Oxalose mit lebensbedrohlichen Ablagerungen in wichtigen Organen führen kann. Eine neue Ursache der Hyperoxalurie entstand mit der Magenbypass-Operation, die eine regelmässige und präemptive Überwachung erfordert. Die Behandlung einer Hyperoxalurie besteht in der Reduktion der Oxalataufnahme und in der Erhöhung der Kalziumzufuhr. Eine optimale Urinverdünnung und Supplementierung mit Inhibitoren der Nierensteinbildung (Zitrat) sind erforderlich. Spezifische Fälle können eine Vitamin-B6-Supplementierung und Zugabe von Probiotika erforderlich machen. Hausärzte sollten Fälle von rezidivierenden Kalziumoxalatsteinen und schwerer Hyperoxalurie erkennen und an spezialisierte Zentren weiterleiten.

Abstract:

Kristalle werden häufig bei der Routine-Untersuchung des Urins gefunden und als Kristallurie bezeichnet. Meistens entsteht die Kristallurie durch eine vorübergehende Übersättigung des Urins. Aber auch Nahrungsmittel, oder Änderungen von pH und Temperatur des Urins, z.B. wenn der Urin nach der Miktion länger stehen geblieben ist, können zu Kristallurie führen. Diese zufällig beobachtete Kristallurie hat keinen Krankheitswert. Der Nachweis von Kristallen im Urin kann jedoch auch mit krankhaften Zuständen, wie Urolithiasis, primärer Hyperoxalurie und Ethylenglycol-Vergiftung einhergehen. Zusätzlich führen verschiedene Medikamente, vor allem antivirale Substanzen und Antibiotika unter bestimmten Umständen zu Kristallurie mit zum Teil schwerwiegenden Nierenschädigungen. In diesen Fällen ist die Untersuchung der Kristalle im Urin zum einen diagnostisch hilfreich zum anderen ist sie ein wichtiger Verlaufsparameter. Voraussetzung für die Beurteilung der Kristallurie ist die korrekte Probenaufbereitung, Bestimmung und Einordnung des Urin-pH und Kenntnis des mikroskopischen Verfahrens.

Abstract:

In spite of high incidence of urolitiasis there is still no integral concept explaining all its causing factors and conditions as well as mechanisms of its development. Judging by the clinical observations one may suppose the androgenous deficiency might boost the formation of stones in the kidneys however there are no decisive proofs of androgenous deficiency role in concrement formation in kidney. These proofs may be yielded by means of a crude experimental model. 60 albino male rats were studied in “ethylenglycol” rat model reproducing urolithiasis for the assessment of androgenous deficiency effect on the development of this disease. “Ethyleneglycol” model of urolithiasis consisted of adding 1 % ethylene glycol solution to drinking water for 4 weeks. Androgenous deficiency was reproduced by castration. The experimental model has successfully produced urolithiasis with considerable disturbances in the structure and function of kidneys including microconcrement formation. Androgenous deficiency (castration) was shown to considerably boost the development of urolitiasis caused by ethylene glycol. In spite of similar morphological signs of urolitiasis in both experimental groups the androgenous deficiency caused by castration has been demonstrated to speed up and worsen the development of the disease. The microconcrements by the papilla of kidney in castrated rats with androgenous deficiency formed earlier and were multitudinous and larger in size than in experimental animals receiving 1 % ethylene glycol solution to drinking water for 4 weeks but without castration.

Abstract:

After the pioneering work of Rostand (1946 CR Acad. Sci. III 222, 1524–1525) and Polge et al. (1949 Nature 164, 666–669) on semen cryopreservation and the reports on the first live young born after storage of mouse embryos for up to 8 days (Whittingham et al. 1972 Science 178, 411–414) or 8 months (Whittingham and Whitten 1974 J. Reprod. Fertil. 36, 433–435) in liquid nitrogen, the world’s first calf was obtained in Cambridge nearly 40 years ago, after freezing and thawing of a bovine embryo (Wilmut and Rowson 1973 Vet. Rec. 92, 686–690). Since then, especially in humans (case reports), the birth of healthy offspring after long-term storage of semen, zygotes, and embryos has been repeatedly reported (e.g. Dowling-Lacey et al. 2011 Fertil. Steril. 95, 1120.e1–3). But practical experiences in different other species such as mice or cattle show contradictory results on the fertility after transfer of long-term-stored gametes or embryos. Here, we report the birth of normal Holstein calves after long-term embryo preservation. After storage for 15 to 22 years, 4 embryos were thawed (air-thaw for 10 s and 25°C water bath for 20 s), which had been originally frozen in 10% glycerol (3 embryos) or in 1.5 M ethylenglycol (1 embryo) following a slow freezing protocol. Removal of glycerol was accomplished with a 4-step dilution procedure and 10.3% sucrose (EMCARETM Thawing System, ICPbio Reproduction, Glenfield, New Zealand), whereas ethylenglycol was removed with a washing step in EMCARETM (Holding Solution, ICPbio Reproduction). The embryos were transferred into the uterine horn ipsilateral to the corpus luteum of recipient cows at 7 days post-oestrus. One embryo was classified as expanded blastocyst grade 1 (7-1), 2 embryos were classified as morulae grade 1 (4-1), and the embryo frozen with ethyleneglycol was classified as a morula grade 2 (4-2) (IETS classification; 40× magnification). Three pregnancies were established (1 × 7-1; 1 × 4-1, and 1 × 4-2), and 3 healthy bull calves were born (18.1.2011, stored 15 years; 6.3.2012, stored 22 years; and 29.3.2012, stored 15 years). These case reports document that long-term-stored bovine embryos maintained developmental competence for up to 22 years of cryopreservation in liquid nitrogen. To our knowledge these cases represent the “oldest” cryopreserved bovine embryos resulting in healthy calves in Germany.

Abstract:

A new water-soluble polyelectrolyte - the copolymer of sodium 2-acrylamido-2-methylpropanesulfonate and ethylene glycol vinyl ether has been synthesized by free-radical copolymerization in aqueous medium. Synthesis of the linear structure water-soluble copolymer of sodium 2-acrylamido-2-methylpropanesulfonate (Na-AMPS) and ethylene glycol vinyl ether (EGVE) has been confirmed by IR spectroscopy method, potentiometric titration and viscometer. The concentration behavior of the reduced viscosity of copolymer solutions that is typical for polyelectrolytes has been revealed. The reactivity ratios for the copolymerization of the monomers estimated by the Mayo–Lewis method have indicated lower reactivity of ethylenglycol vinyl ether in comparison with sodium 2-acrylamido-2-methylpropanesulfonate. Also it was shown the decrease of reaction’s relative rate with an increase of molar fraction of EGVE in the initial mixture of monomers. Adsorption at the air-water solution interface was studied by measure of surface tension (σ) in order to determine the surface properties of new copolymers of ethyleneglycol vinyl ethers – sodium 2-acrylamido-2-methylpropanesulfonate. It was shown that copolymers of sodium 2-acrylamido-2-methylpropanesulfonate and ethylenglycol vinyl ether have higher surface activity compared to sodium 2-acrylamido-2-methylpropanesulfonate homopolymer. The isotherm of copolymer’s surface tension based on equilibrium value of σ was constructed together with the isotherm of surface tension water solution poly- Na-AMPS. Based on isotherms the surface activity on Rebinder (GRe) for poly- Na-AMPS and copolymer Na-AMPS-EGVE was determined. The values of polymer’s standard free energy of adsorption (ΔadsG0298) were calculated in order to identify the causes and mechanism of change in surface activity and adsorption. Results show that the gain in standard free energy adsorption in the transition from homopolymer to copolymer Na-AMPS-EGVE is about 4 kJ/base-mole. Interpolymer reaction of the Na-AMS–EGVE copolymer with poly- N,N-dimethyl-N,N-diallylammonium chloride (PMAAC) has been studied. Higher surface activity of mixtures of copolymer and PMAAC than of individual polyelectrolytes was discovered. This effect testified to the formation of interpolymer complex of the Na-AMS–EGVE copolymer with polycations due to electrostatic interactions.

Full text

Abstract:

In this paper corrosion properties and microstructure features of amorphous self-organised TiO2 nanotubes electrochemically deposited on titanium are discussed. There was titanium of second grade used as a substrate for these experiments. There was a specific solution of ammonium fluoride, ethylenglycol and deionized water used to create an oxide layer with advantageous properties. Relation between changes of roughness indexes before and after anodization was found out. The wettability (contact angle) of artificial plasma on surface was measured using sessile drop method. It was found out that titanium dioxide nanotubes formed on the surface significantly decreases contact angle and time of anodization reduces it even more. Corrosion potentials, corrosion rate or polarization resistance were determined by linear polarization methods performed by ASTM standards. Corrosion potential of anodized samples is substantially more positive (≈ -50mV) compared with non-treated sample (≈ - 280mV). On the other hand polarization resistance was significantly higher for non-treated sample. Also potentials of passive layer breakdowns were found. Structure of nanotubes and influence of anodization on surface profile was studied by SEM.

Abstract:

Polymeric nanofibers (NFs) have been extensively reported as a biocompatible scaffold to be specifically applied in several researching fields, including biomedical applications. The principal researching lines cover the encapsulation of antitumor drugs for controlled drug delivery applications, scaffolds structures for tissue engineering and regenerative medicine, as well as magnetic or plasmonic hyperthermia to be applied in the reduction of cancer tumors. This makes NFs useful as therapeutic implantable patches or mats to be implemented in numerous biomedical researching fields. In this context, several biocompatible polymers with excellent biocompatibility and biodegradability including poly lactic-co-glycolic acid (PLGA), poly butylcyanoacrylate (PBCA), poly ethylenglycol (PEG), poly (ε-caprolactone) (PCL) or poly lactic acid (PLA) have been widely used for the synthesis of NFs using the electrospun technique. Indeed, other types of polymers with stimuli-responsive capabilities has have recently reported for the fabrication of polymeric NFs scaffolds with relevant biomedical applications. Importantly, colloidal nanoparticles used as nanocarriers and non-biodegradable structures have been also incorporated by electrospinning into polymeric NFs for drug delivery applications and cancer treatments. In this review, we focus on the incorporation of drugs into polymeric NFs for drug delivery and cancer treatment applications. However, the principal novelty compared with previously reported publications is that we also focus on recent investigations concerning new strategies that increase drug delivery and cancer treatments efficiencies, such as the incorporation of colloidal nanoparticles into polymeric NFs, the possibility to fabricate NFs with the capability to respond to external environments, and finally, the synthesis of hybrid polymeric NFs containing carbon nanotubes, magnetic and gold nanoparticles, with magnetic and plasmonic hyperthermia applicability.

An ultra-slow inactivation in the amplitude of HVA calcium currents, with an average slow time constant of 149.3 s for peak currents and 159.1 s for sustained currents (n = 9), was unveiled during 5-min step depolarizations in Vh. 3. The ultra-slow inactivation of HVA calcium currents was found to be generated by at least two processes: a voltage-dependent inactivation that increases with increasing depolarization in Vh and an activity-dependent inactivation that is initiated, but not increased, with increasing depolarization in Vh. The relative contribution of the activity-dependent component to the ultra-slow inactivation was 80% when Vh was stepped from -80 to -60 mV and only 40% when Vh was stepped from -80 to -40 mV. 4. The activity-dependent inactivation of the HVA currents was not altered significantly in experiments in which barium replaced calcium as charge carrier and 1,2-bis (1-aminophenoxy) ethane N,N,N' N'-tetraacetic acid (BAPTA) was used as an intracellular calcium buffer instead of the less potent ethylenglycol-bis-(beta-aminoethylether) N,N,N' N'-tetraacetic acid (EGTA). In addition, activity-dependent inactivation was observed with sodium as the charge carrier through the calcium channels. 5. The activity-dependent inactivation depends on divalent cation influx. The activity-dependent inactivation was abolished when the test potentials, during the depolarization in Vh, were increased from 0 to +70 mV (close to the reversal potential for calcium currents under our experimental conditions). This reduction in driving force for calcium currents eliminated divalent cation influx and abolished the activity-dependent inactivation. 6. The activity-dependent inactivation lacks several characteristic features for calcium-dependent inactivation, such as dependence on charge carrier (see above), dependence on the size of the calcium current, and increase in decay rate of the calcium current during the test pulse. These latter notions were also supported by our paired pulse experiments, in which the calcium current elicited by a constant test pulse was virtually unaffected (7%) by conditioning pulses that produced maximal calcium currents. We therefore conclude that the dependence of activity-dependent inactivation on divalent cation influx cannot be attributed to the known form of calcium-dependent inactivation. 7. In conclusion, this study shows that calcium influx through HVA channels in anterior pituitary cells can be regulated by subthreshold changes in membrane potential and that the extent of this regulation depends on low-frequency activation of HVA calcium channels during the depolarization in membrane potential. Thus the pituitary cell may regulate hormone secretion by changes in membrane potential and in a use-dependent manner via regulation of calcium influx.

Abstract:

T The aim of the article. The aim of this study was to evaluation of the effectiveness of standard antidote therapy and dimephosphon administration in rats with acute ethylene glycol poisoning. The tasks of the study included modeling acute ethylene glycol poisoning in rats, conducting experimental therapy with ethanol antidote in combination with sodium bicarbonate and dimephosphon therapy, comparing the effectiveness of drugs in relation to indicators of acid-base state impairment and renal function. Materials and methods. Ethylene glycol (EG) was administered per os to Wistar male rats (190-210 g b.w.) at a single dose of 6 mL / kg b.w. through an atraumatic gastric tube. The animals were divided into 4 groups of 6 individuals each: intact (negative control), EG poisoning (positive control), EG + standard antidote therapy, EG + dimephosphon therapy. Experimental therapy was carried out for first 24 hours using standard antidote therapy: ethanol (30% solution 2 mL / kg b.w. i.p. after 1, 4, 6, 12, 18 hours) and sodium bicarbonate (4% solution 6 mL / kg b.w. i.p. 3 times on the first day), as well as administration of dimephosphon (150 mg / kg i.p. 3 times on the first day, 450 mg / kg b.w. per day). Daily urine on day 3 after poisoning was collected in metabolic cages. Creatinine concentration in urine and blood serum samples were measured, and creatinine clearance was calculated. After 24 hours of therapy, the pH, level of sodium, potassium, calcium, magnesium, chlorides, bicarbonates, lactate, d-3-hydroxybutyrate, albumin, urea and creatinine (measured parameters) were determined in venous blood samples. Anion gap, ∆рН, ∆AG, ∆HCO3, ∆AG/∆HCO3 and ∆Gap were calculated. The mechanism of death was determined for the dead animals. Data processing was performed using GraphPad Prism 6.0. Results. Acute poisoning of rats with ethylene glycol leads to the development of toxic encephalopathy and nephropathy, acid-base abnormalities, high anion gap metabolic acidosis due to the presence of metabolites, as well as lactate-ketoacidosis due to depression of the central nervous system and hunger. 100% of the EG-treated (12 mL / kg b.w.) animals died within 3 days. Metabolic acidosis in combination with hypermagnesemia had provided a cardiodepressive effect, which with direct nephrotoxic and neurotoxic effects contributed to the development of a mixed variant of thanatogenesis and death. Death comes from toxic encephalopathy and nephropathy, high anion gap metabolic acidosis caused by direct nephrotoxic and neurotoxic effects of EG and its metabolites. The standard antidote therapy with ethanol in combination with sodium bicarbonate prevented a pH shift, lactic acidosis and ketoacidosis, an increase in urea, but did not affect the level of bicarbonate (p=0.048), creatinine and its clearance (p=0.037) and the anion gap (p=0.033). The dimephosphon therapy prevented a decrease in creatinine clearance and blood bicarbonate level, limited the increase in lactate dehydrogenase activity, had a more pronounced effect on the AG and ∆AG (p=0.042), but did not affect the hypocalcemia (p=0.0076) and hypoalbuminemia (p=0.021). Conclusion. Acute ethylene glycol poisoning leads to the development of a mixed variant of thanatogenesis with damage to the central nervous and urinary systems, as well as the heart. Autopsy and histopathology confirmed the cause of animal death. In the model at a dose of 6 mL / kg of EG the dimephosphon therapy was more conducive to the correction of the main markers of high anion gap metabolic acidosis (HAGMA) than standard antidote therapy (both measured and calculated, p0.05). The dimephosphon therapy prevented a decrease in creatinine clearance. A comparative analysis of two methods for the correction of high anion gap metabolic acidosis in rats in acute poisoning with ethylene glycol showed that dimephosphon therapy vs. standard antidote therapy had a stronger effect on markers of metabolic acidosis and renal impairment.
