Histochemical studies in experimental trichinosis.
The study of the behaviours of Trichinella spiralis in the host tissues from the histochemical point of view will throw a light on parallelism of the destruction process by the infection and the instruction of the host tissues, i.e., the catabolic effect of the parasite as an indicator of the severity of infection and the anabolic response by the host as a criteria of cure. So, this study revealed a definite increase in catabolic enzymes as acid phosphatase activities. A relative disturbance and a decrease of anabolic enzymes (succinate dehydrogenase, alkaline phosphatase, non-specific esterase and adenosine triphosphatase (ATPase) reactivity which indicates the destructive effects of T. spiralis adult worms and encysted larvae on intestinal mucosa alpha striated muscles of tongue and diaphragm. The disturbances of anabolic enzymes activity revealed the continuous trials of the host to get rid of adult worms from the small intestine, and to defeat and isolate the larvae in striated muscles. While the renal tissue changes indicate the disturbance of absorption and excretion functions of renal tissue due to the presence of endmetabolites and products of the parasite in the host blood.
