SOME ASPECTS OF THE ACETYL CHOLINE METABOLISM SHORTLY AFTER EXPOSURE TO A SUBLETHAL DOSE OF $gamma$-RAYS (in Russian)
Following up previous findings (Radiobiologiya 1: 761 (1961)) that exposure of rats to gamma rays at a dose of 800 r affects the animals' acetyl choline metabolism, similar exposure tests were carried out at sublethal doses. After exposing the white rats weighing 180 to 200 g to a dose of 100 r from a Co/ sup 60/ source, groups of them were killed at the end periods ranging from 10 minutes to 24 hours. Comparison of the acetyl choline content in the brain, liver, and the small intestine of the test and the control animals, it was found that the short, 13-sec exposure to the 460 r/min source caused noticeable changes even after 10 minutes in the free and bound acetyl chollne concentration, the activity of the acetyl choline esterase and of the nonspecific choline esterase in the tested tissues. These changes are probably due to compensating reactions of the organism. (TTT)
