دراسة كيميائية نسجية للتحري عن الكاربوهيدرات و البروتينات و الدهون و دورها الفسلجي في المذنبات دقيقة الذيل و ثنائية الممص

الملخص EN

Histochemical techniques revealed the presence of proteins, carbohydrates and lipids in both microcercous and distome cercariae.

There was an abundance of glycogen and different mucopolysaccharides when lead tetra acetate-Schiff technique was used, but the result was negative in case of microcercous cercariae when maxilon blue RL technique was used as no metachromatia was noticed.

The reaction was moderately positive with distome cercariae by using the same technique.

Also there was an abundance of proteins containing tryptophan and arginine in tissues of both cercariae.

Both cercariae showed very strong positive reaction with the technique used to detect lipoproteins.
