[Effect of ether anesthesia on pentosephosphate cycle dehydrogenase activity in different parts of the brain].

Investigations carried out on 19 dogs demonstrated that under ether anesthesia and with the anesthetic concentration in the arterial blood of 126.4 +/- 15.4 mg% the activity of the glucose-6-phosphate and 6-phosphogluconate dehydrogenases in the optic and auditory areas of the brain cortex as well as in the median thalamus experiences no significant changes.
