title: Localization of some enzymes in polycephalic larva of Hydatigera krepkogorski (Schultz et Landa, 1934).
abstract: High activity of alkaline phosphatase, acid phosphatase and non-specific esterase was demonstrated by histochemical methods in the tegument of scolex of a polycephalic larva of Hydatigera krepkogorski (Schulz et Landa, 1934). The nerve cells and fibres of scolex and bladder exhibited a high activity of alkaline phosphatase and non-specific esterase. Both enzymes were present also in sensory endings. In the bladder, the activity of alkaline and acid phosphatase and non-specific esterase was localized in the tegument and subtegumental cells. High activity of alkaline phosphatase in the tegument of scolex and bladder indicates a high transport of substances in these parts of larva. In the scolex, the activity of alkaline phosphatase was higher than the activity of acid phosphatase, whereas in the bladder tegument and subtegumental cells, the activity of alkaline phosphatase was lower than that of acid phosphatase.
