Histochemical observations on the ovaries of some Indian bats

Ovarian follicles of the three species of bats, Pteropus giganteus giganteus, Taphozous longimanus and Megaderma lyra lyra were studied with regard to the distribution and nature of mucopolysaccharides. Oocyte contained only glycogen. Zona pellucida showed the presence of glycogen, neutral mucosubstances, sialo- and sulfomucins. Follicle cells showed the presence of glycogen and sialic acid except in megaderma lyra lyra where the follicle cells of the Graafian follicle showed the presence of sulfomucins in addition to these mucosubstances Cumulus cells contained glycogen., sulfomucin, sialomucins and hyaluronic acid. Liquor follicular showed the presence of sulfomucins, sialomucins and hyaluronic acid. Theca cells contained glycogen and sialic acid. The luteal cells contained glycogen only.
