Hepatic metabolic derangement following preoperative irradiation gastric neoplasms

Preopeartive irradiation of gastric cancer results in glycogene buildup in the heratic cells and activation of a number of tissue enzymes such as glutamate-and lactate dehydrogenases, hexogenase, choline esterase and aspartate aminotransferase in the left lobe of the liver which is included in a zone of direct irradiation. The enzyme activation is observed on the 4-7th day after the course of radiotherapy, glycogene maximum content - on the 5th day. The enzyme activity and glycogene content on the 11th day after irradiation decreases to the level of their content in the patients who have not been subjected to radiotherapy
