Abstract
Summary
An overnight fast resulted in decrease in weight of liver of rats and mice with a proportionate decrease in their aspartic- and alanine-glutamic transaminase activities except for the aspartic-glutamic transaminase of mouse liver which maintained its total activity. Homogenates of liver and heart prepared in water had the same alanine-glutamic transaminase activities as those prepared in 0.05 M potassium phosphate (pH 7.4) but the kidney enzyme was lower in buffer. The aspartic-glutamic transaminase activities of liver and kidney were higher in water homogenates while that of the heart was higher in buffer.
