The activity was determined of sorbitol-dehydrogenase (SDH), cholinesterase (CE), leucine-aminopeptidase (LAP), acid phosphatase (AP), and glutamate-dehydrogenase (GDH) in blood plasma of lambs irradiated with 200, 320, and 450 Rad. Results showed that with the mild form of acute radiation sickness (treatment with 200 Rad) the activity of the blood enzymes did not change. With the severe (320 Rad) and the peracute (450 Rad) forms of the disease within the first 24 hours the activity of SDH and CE rose 3 to 5 times, and that of GDH and AP--twice within a period of 1 to 3 days following irradiation. In the case of a threefold increased activity of SDH and CE within 15 to 24 hours of treatment the diseased animals died. Parallel hematologic investigations revealed that well manifested leukopenia with these two forms of the sickness took place after the 24th hour. Activity determination of the investigated plasma enzymes within the first 15-24 hours following irradiation could be used as an adjunct test to the study of the hematologic indices for the early diagnosis of the severe and peracute forms of irradiation sickness as well as for the exit of the disease.

The morphologic changes in the liver were investigated along with those in the activity of the specific liver enzymes in the blood plasma of rats in the case of the severe form of acute radiation disease. The rats were treated with 670 Rad at the rate of 90 Rad/min. The studies were carried out on the 1st, 8th , 15th, 22nd, and 30th day following irradiation. It was found that under the conditions of the experiment the activity of the cytoplasmic enzymes sorbitoldehydrogenase , cholinesterase, and leucinaminopeptidase strongly rose on the 1st day after treatment (the activity of sorbitoldehydrogenase increased 11 times). The activity of acid phosphatase and glutamate dehydrogenase also increased strongly, whereupon there was deterioration of the mitochondrial and lysosomal structures. Seen were well expressed processes of fatty and parenchymal dystrophy. The studies on the changes in the activity of these enzymes can be used as an adjunct, resp., an auxiliary test to the haematologic indices in the evaluation of the severity of radiation disease.
