| Abstract: | Distribution of acylase in different tissues of nine species of animals was studied. The following types of nitrogen elimination were distinguished: ammoniatelic (fish), uricotelic (birds) and uriotelic (amphibians, mammalians). The enzymic activity was estimated in the tissues of the brain, lung, muscle, liver, kidney, spleen, pancreas, small intestine and blood serum. The acylase activity was found in the kidney, liver and pancreas. Its level in the kidney increases with the animal weight growth, the enzyme activity being observed only in the cortical layer. |
