title: [Pharmacokinetics and enzymatic transformations of 35S-lincomycin in the tissues of certain organs].
abstract: Pharmacokinetics of 35S-lincomycin was studied with the microbiological and radiometric methods of the antibiotic determination. Significant deviations in the results obtained with the two methods in determination of lincomycin levels in the liver and kidneys were observed. The values obtained with the radiometric method were 10 times higher than those obtained with the microbiological method. Paper radiochromatography of the extracts from the liver and kidneys of the animals treated with 35S-lincomycin revealed the presence of not only 35S-lincomycin, but also a number of the label containing substances, the products of the antibiotic enzymatic transformation. Radiochromatography of the extracts from the brain of the animals treated with 35S-lincomycin revealed several peaks of radioactivity against the back ground of low levels of the label.
