Effect of bemythyl on carbohydrate metabolism in cirrhotic rat liver

Effect of actoprotector bemitil (2-ethylthiobenzimidazole hydrobromide) on glycogen content and activities of glycogen synthase, glycogen phosphorylase, and glucose-6-phosphatase was studied in cirrhotically altered rat liver. The contents of glycogen and its fraction were determined a cytofluorimetrically (Kudryavtseva et al., 1974). In cirrhosis, the total glycogen content in hepatocytes increases by nearly 3 times, while the amount of a stable fraction of glycogen rises by 7.5 times. Glucose-6-phosphatase activity fell to the level of 25% compare to the norm. Activities of glycogen synthase and glycogen phosphorylase in the cirrhotic liver did not differ from the norm. In cirrhotically altered liver, bemitil produced a decrease in the total glycogen content due to a decrease in glycogen synthase activity in an increase in glucose-6-phosphatase and glycogen phosphorylase activities. The above results suggest a favorable effect of bemitil on cirrhotic liver.
