Studying the Harmlessness of Antimicrobial Drug Triolact for White Rats

Abstract

The aim of the research was to study the effect of the complex antimicrobial drug Triolact on blood’s morphological and biochemical parameters in white rats in a subacute toxicity experiment. It was shown that threshold dose was 500.0 mg/kg, while highest no-effect dose was 100.0 mg/kg. Triolact did not have a negative effect on the clinical status, biochemistry, or blood cell morphology after 14 days of repeated intragastric administration of 100.0 mg/kg or 250.0 mg/kg either during the application of the drug or in the recovery period. The changes caused by the dose of 500.0 mg/kg were reversible. Increase in α-globulin, creatinine, and urea levels were 6.9, 22.9, and 15.1% respectively, but these indicators in test animals returned to normal within the 10 days of the recovery period. It can be concluded that the determination of the toxic dose in the performed experiments failed with consideration for the morphometric analysis, macro- and microscopic examination of organs, and morphology and biochemistry of blood.
