[Localization of receptors for phytospermoagglutinin from Arum maculatum on human spermatogenic cells and spermatozoa].

Our precious studies showed that delipidized water-saline extract from roots of Arum maculatum (AM) contained lectin-phytospermoagglutinins (PSA), which caused agglutination, manifested by the type of a tail with a tail and a head with a tail. This extract we conjugated with fluorescein-isothiocyanate and by means of the conjugate we studied the localization of receptor molecules for PSA on the plasmalemma of human spermatogenic cells and human spermatozoa, obtained from the testis, epididymis and ejaculate. It was established that receptor molecules for PSA were distributed irregularly on the plasmalemma of spermatozoa, that the basic part of these molecules were synthesized on spermatogenic cells and that ejaculate spermatozoa adsorbed such molecules from the sperm plasma.
