[Enzyme activities in the blood serum from rats with chronic liver damage. part 3: Effect of thioacetamide].
Liver damage was produced in male Wistar rats aged 15 weeks by daily oral administration of 40 mg/kg thioacetamide over a period of 24 weeks. All of the animals were weighed once a week. Furthermore, the duration of hexobarbital anaesthesia and the activities of the enzymes ASAT, ALAT, GIDH, LDH, LAP and alkaline phosphatase in the serum were determined in 6 experimental and 4 control animals after 3 d and 1, 2 and 4 weeks, and then at intervals of 4 weeks. For the purpose of comparison the same investigations were performed (under identical experimental conditions) both in rats fed normally and rats starved for 24 h to which a single dose of thioacetamide was applied. The histological study of the livers revealed destruction of the lobule architecture and profuse bile-duct proliferations after 12 weeks. Cirrhosis was observed after 16 weeks. The activities of ASAT, ALAT, GIDH and LDH increased for a short time and then returned closely to normal. During the whole experimental period, the LAP and alkaline phosphatase activities remained in the pathological range, as well as the duration of hexobarbital anaesthesia. Enzyme diagnosis is not suitable for assessing the degree of severity of a liver damage produced by thioacetamide.
