[Change in aminotransferase and alkaline phosphatase activity in rats exposed to plutonium-239 in combination with external gamma-radiation]. / Izmenenie aktivnosti aminotransferaz i shchelochnoi fosfatazy u krys pri sochetannom vozdeistvii plutoniia-239 i vneshnego gamma-oblucheniia.

Activity of alanine- and aspartate aminotransferases and alkaline phosphatase in the liver and blood serum was studied during 17 months after the administration of plutonium-239 (92.5 kBq/kg) to rats preirradiated with gamma-rays (103.2 and 51.6 mC/kg). The dynamics of changes in the activity of the enzymes under study was undulatory; the changes observed in the enzymic activity under the combined effect of the two types of radiation exhibited certain distinctions from those caused by their separate action.
