Histopathological, histochemical and biochemical studies on hepatic hydatid cysts of some animals

ABSTRACT

Cystic echinococcosis is considered as a major cosmopolitan zoonotic disease affecting the health of man. Naturally infected hepatic cysts from camels, pigs, and sheep were collected from El-Basateen abattoir for histopathological, histochemical and biochemical, studies. Total proteins, uric acid, urea, cholesterol, triglycerides, AST, ALT, GOT, Alkaline phosphatase LDH, Na, K, and calcium showed a higher concentration in fertile cysts while creatinine only had a higher concentration in sterile ones. Dystrophic changes were observed in the infected liver specially around the cyst wall and around the portal areas this was accompanied with increased collagenous fibres. The cyst wall showed remarkable reaction for total proteins in camels and pigs associated with less stain affinity in the hepatocytes. A remarkable reaction for polysaccharides was detected in the cyst wall of all the studied animals comparing to hepatocytes
