[The activity of acetyl COA hydrolase (AACo) and aminotransferases AspAT and AlAt in the course of experimental hymenolepiasis].

Buffalo male rats were infected with Hymenolepis diminuta. On 7th, 14th, 21st, 28th and 52nd day of infection blood and liver were collected to determine AACo, AspAt, AlAt in the blood serum and in liver homogenates. In the course of teniosis in rats the activities of all examined enzymes show changes in the serum and in liver homogenates. The most pronounced ones occur between the 7th and 21st day of infection. In the authors' opinion this is related to the highest pathogenicity of H. diminuta and especially with toxic action at this time. Determination of AACo activity proved to be a useful test to follow up the dynamics of organ changes in the course of hymenolepiasis.
