The rat tapeworm, Hymenolepis diminuta, induces mastocytosis, hypertrophy of enteric smooth muscle, alteration of enteric myoelectric activity, and slowed enteric transit of the rat host's intestine. This report examines the resolution of both tapeworm-induced mastocytosis and tissue changes during
A large number of eosinophils were recruited to the intestinal villi after infection with Hymenolepis nana. Eosinophil numbers were increased more rapidly in challenged mice than in primary infected mice. Local intestinal eosinophils from challenged mice showed more extracellular oxygen radical
The pathological and immunopathological effects of H. nana on experimentally infected albino mice were studied, sacrificed one, three and five months post egg inoculation. The results showed that most of the mice had diarrhoea, loss of appetite and were inactive. On the other hand, the liver and
The intestinal morphology of rats given one, 10 or 100 cysticercoids of hymenolepis diminuta was examined by scanning electron microscopy. The presence of this tapeworm causes extensive villous atrophy and fusion. The most extreme changes in mucosal architecture were observed adjacent to the mature
The fine structure of the envelopes surrounding hatched and unhatched oncospheres of Hymenolepis nana has been investigated by transmission and scanning electron microscopy (SEM), together with light microscope histochemical observations of JB-4 embedded material. The oncosphere is surrounded by 3
