Morphological characteristics of liver and mucosa of small intestine of piglets in the application of enrofloxacin and colistin

Intramuscular injection of the drug on the basis of compositional enrofloxacin and colistin in doses of 0,5, 1,0 and 2,5 ml per 10 kg weight of the animal within 20 days of piglets did not violate arhitektotoniku girder structure of the organ and morphometric parameters of hepatocytes. Use of the drug did not alter the amount and distribution of the lobules of the liver glycogen and lipid content of DNA in the nuclei and RNA in the cytoplasm of hepatocytes, as well as the amount of total proteins in hepatocytes. The composite preparation on the basis of enrofloxacin and colistin of piglets had no effect on the structural organization of the mucosa of the small intestine and morphometric parameters, as well as DNA content nuclei and RNA in the cytoplasm. It does not change the core area, area and cytoplasmic-nuclear ratio of enterocytes apical and lateral surfaces of villi and crypts.
