Skeletal muscle metabolism in mice bearing adenocarcinoma. I. Histochemical alterations in glycogenolytic, glycolytic, lipolytic and oxidative metabolism

Skeletal muscle metabolism in mice bearing adenocarcinoma. III. Activities of alanine and aspartate aminotransferases

Activities of alanine and aspartate aminotransferases in six skeletal muscles demonstrate 114-223% and 86-146% increase respectively, over the normal by the 10th week after adenocarcinoma transplantation in mice. The white (anaerobic) muscles reveal greater increment in these two enzymes than the red (aerobic) ones. The significance of elevated aminotransferase activities in energy metabolism of the host muscles is discussed.

Skeletal muscle metabolism in mice bearing adenocarcinoma. II. Histochemical alterations in acid and alkaline phosphatases

In Swiss albino mice bearing adenocarcinoma the degree of pathological damage as revealed by the activities of acid and alkaline phosphatases is greater in skeletal muscles closely proximal to the tumor site than in those away from it. Acid and alkaline phosphatases in myofibres of triceps, pectoralis and gastrocnemius muscles show a direct relationship between myofibre necrosis and activities of these phosphatases.
