To date, special attention should be paid to drugs that have antimicrobial, anti-inflammatory and wound-healing effects, one of which is sodium-containing drugs. The article presents the results of experimental studies to study the acute toxicity of sodium-containing drugs: glycetinate 2 %, its analogues – ovocid 2 %, ovocid 3 %, potassium-sodium 1.5% (Na/K 1.5 %). The study of 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 - Nа/К 1,5 %, 3rd group - ovocid 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. The studied drugs did not cause visible disorders of physiological functions, the appearance of clinical signs of intoxication. There were no significant clinical signs of inflammation or irritation (erythema, edema and cracks) on the skin of the animals, but there was a slight redness at the application site, which later disappeared. The studied sodium-containing preparations (ovocid 3 %, Nа/К 1,5 %, ovocid 2 %, glycetinate 2 %) under the conditions of a single application of the preparation to the skin of animals did not cause the death of animals, which allows us to classify these preparations as low-toxic substances.
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.
Sodium-containing preparations have antimicrobial, anti-inflammatory and wound-healing activity, which determines their use in veterinary medicine. This effect is due to a wide range of physiological effects of sodium ions on animals metabolism. The article presents the results of experimental studies of the irritant effect of sodium-containing drugs: known – 2 % glycetinate, its analogues – 2 % ovocid, 3 % ovocid, 1.5 % potassium-sodium drug (Na / K, 1.5%). Studies of irritant and skin-resorptive action of drugs were performed by immersing the tail of animals in a test tube with the substance on white rats weighing 250–270 g. Four groups of rats were formed with 3 animals each: rats of I group (control) tails were immersed in test tubes with 2 % glycetinate, animals of II group – in test tubes with 2% oocide, III group – in test tubes with 3 % oocide, and in IV group rats – with Na / K, 1.5% drug. The exposure time was 4 hours. The animals were subjected to clinical observations, assessing their general condition and the reaction of the tail’s skin. The effect of drugs on the morphological and biochemical parameters of the rats blood was studied. The study of the local irritant effect of the studied drugs in rats from I, II and III groups showed a moderate local irritant reaction, as evidenced by the appearance of redness and thickening of the skin, and in group IV animals appeared only slight redness on the skin of the tails. This indicates a weaker local irritant effect of potassium-sodium-containing drug (1.5% K, Na), compared with other studied drugs. According to hematological studies, in the rats’s blood of groups III and IV, a reliable increase, within normal limits, the number of leukocytes and a decrease in hemoglobin content, compared with those of animals of group I. It was found that at 4 hours of the experiment under the action of the studied potassium-sodium drugs increases the permeability of Sodium and Potassium through the rats’s skin into the blood. In particular, in serum of animals from groups II and IV there was a reliable increase of Potassium content by 2.1 times, respectively, and a significant increase in Sodium content in the blood of animals from groups III and IV, compared with control group. In animals of groups II and IV there was a reliable increase of serum aspartate aminotransferase activity, and in rats of group III – increase of serum alanine aminotransferase, alkaline phosphatase activity and in triacylglycerol’s content, compared with rats of group I, which indicates the effect of 2 % glycecin analogues on metabolic processes in animals.
