[Enzymatic and morphological study of the liver in acute radiation sickness].
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.
