Leucine amonopeptidase (LAP) activity was histochemically studied in the rat exorbital lacrimal gland. The enzyme is present in the secreting cells of both male and female prepuberal rats, in vivo and in monolayer cultures, while in the adult rat it is demonstrable only in the female. Furthermore, LAP is influenced by the sex hormones, disappearing in the female gland after testosterone treatment and appearing in the adult male gland after administration of estradiol or cyproterone acetate.

The tubular localization of binding sites for 125I-FSH is demonstrated in vitro by the autoradiography on frozen sections of boar-testis. The uniform distribution of silver grains throughout the seminiferous epithelium suggests the presence of receptors for FSH also in the adluminal compartment. Similar results have been obtained using rat testis.
