The activity of hexokinase, glucose-6-phosphatase and glucose-6-phosphoric dehydrogenase was studied in the liver of rats after one hour, one and five days after a single oral administration of organic phosphorus insecticide valekson. It was determined that administration of the preparation led to an increase of activity in the homogenate and solubilization of glucose-6-phosphatase, activation of glucose-6-phosphoric dehydrogenase and inhibition of hexokinase. The changes were maximum one hour after the administration of the compound. The results show that a decrease of the intensity of glucose-6-phosphate formation and metabolism is one of the pathogenetic factors in the development of valekson-induced intoxication.
