抄録: The epithelium of the so-called prostate gland of Suncus murinus temminckii Fitzinger was observed electron microscopically. The several rough endoplasmic reticulum are in a row at the infra- and perinuclear region of the cell, but at the apical portion of the cell and at the supranuclear region the rough endoplasmic reticulum presents an vesicular form. The Golgi apparatus is well developed at the supranuclear region and the dense small granules which seem to be condensed, were often observed within the distended vacuoles of the Golgi apparatus. Many dense and homogeneous secretory granules are scattered from the supranuclear region to the apical portion of the cell. These granules situating at the apical portion of the cell are surrounded by a membrane-bounded vacuole, in which the small microvilli-like cytoplasmic projections to the granule were apparently observed. The secretory granules become coarse and low in electron density from the periphery of it, but a finger-print-like structure is present in the center of the secreting granule. The fingerprint- like structure is also obsrved in the secreted granule in the lumen of the gland. The free surface of the epithelial cell usually appeared ruffled and possessed many long microvilli. The cells are progressively reduced in the gland of the castrated animal and the organellae become less organized and the secretory granules decrease in the size and number, but not utterly diminished in this experiment. The secretory activity is recovered by the administration of testosterone and the cell becomes similar to that of the intact animal.
