| Abstract: | The results are reviewed from studies of activity of hexokinase (2.7.1.1.EC), dehydrogenase glucose-6-phosphate (1.1.1.49 EC), and cholinesterase (3.1.1.7 EC) in subcellular fractions of rat brain at the background of chemical sympathectomy induced by long-term administration of guanethidine and subsequent irradiation with a dose of 7 Gy. In conditions of sympathectomy, the enzyme activity is inhibited; in irradiated sympathectomized rats, activity of hexokinase and cholinesterase increases to reach the level of that of intact animals while dehydrogenase remains inhibited. |
