Smolyaninov K. Influence of age and vitamin A on lipid metabolism in cattle lungs

The object of the research: fetuses, calves, bulls. The aim of the work: to study the ontogenrtical peculiarities of lipid metabolism in cattle lungs and influence of vitamin A on lipid synthesis in calves lungs. Methods of research and equipment: biochemical, radioisotope method. Spectrophotometr, pH-metr, liquid scintilator counter. Theoretical and practical results: It was established that during ontogenesis the content of total lipids,phospholipids and cholesterol ethers decreases and triacylglicerols and free cholesterol content increases in cattle lungs. Lipid synthesis intensity from acetic, palmitic, oleic, stearic, and linolenic acids in calves lungs is higher than in fetuses and adult animals. Vitamin A influences differenly on the synthesis of separate lipid classes in calves lungs. The area of use: therapy and prophylactics of lungs pathology.
