In the course of experimental hymenolepidosis in rats, varying mobilization of mastocytes, dependent on the organ of their origin, was observed. The highest was in the small intestine, lower in the mesenterial lymph nodes and the spleen. Various degree of correlation between the mastocyte mobilization and the histopathological changes was stated.
The acethylcholine level was determined by pharmacologic method in properly selected experimental and control groups of mice. Selection was made as to the strain, age, body weight and time that elapsed since the induction of experimental infection. After isolation of the diaphragm, inactivation of choline esterase by physostigmin, acetylocholine was extracted in a solution at pH of 3. The contraction of the dorsal muscle in leech, due to the effect of extracts from the diaphragm of infected and control muscles were compared with those that occurred under the influence of colutions obtained from cristalline acethylcholine. The experiments were made at 2, 3, 4, 5, 6, and 12 weeks of infection. The acethylcholine level in the diaphragmatic muscle of Trichinella-infected animals was found to be higher than that of normal ones (fig. 1), and to show an increasing tendency up to the 4th week of infection; the subsequent decrease was lower at 12 than at 2 weeks p. i.
Bauflo male rats were infected with Hymenolepis diminuta. On 7th, 14th, 21th, 28th and 52th 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 activitics 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 hymenolepidosis.
