Studies on the integument of cestodes. VI. Histochemical studies on the fate of structural polysaccharide in the integument of gravid proglottides of Taenia hydatigena.

Histochemical study of the structural polysaccharide in the integument of gravid proglottides revealed that the main cuticle is only feebly positive to PAS reaction when compared with that of other regions of the cestode body. The significance of such change in the PAS reaction has been discussed. It was observed that there is no change in the acid mucopolysaccharide of the outer layer of the integument.
