[Changes in enzymatic activity in rats with acute Unden poisoning]

The influence of Uden, exerted on the activity of GOT, GPT, LDH acid phosphatase and alkaline phosphatase in the serum, is investigated upon 4-day-long treatment. The experiment is conducted in three groups of white male rats with mean weight 270 +/- 20 g. The first group of animals underwnt poisoning with 1/20 LD50, the second--with 1/4 LD50 while in the third, control group, the animals were treated with an oil solvent at the respective days. It is found that acid phosphatase, GOT and alkaline phosphatase activity in group two is virtually unchanged, whilst GPT activity in both experimental groups, and acid phosphatase in group one are reliably increased (P less than 0,01), with 20,17 and 53 per cent respectively. LDH activity is reliably lowered with 60 per cent in group two, whereas in group one a tendency for a reduction is noted (P less than 0,05).
