title: [Changes in the dry weight of retinal pigment epithelium cells in the postnatal ontogeny of rats].
abstract: The dry weight of cytoplasm of individual cells of the retinal pigment epithelium was determined by interference microscopy in the rats (both in mononuclear and binuclear cells). During postnatal development the dry weight of cell cytoplasm is subject to fluctuations: it increases from the 1st till the 5th day, decreases between the 5th and 15th days and increases again between the 15th and 18th days. It is suggested that the decrease in dry weight of cytoplasm of the retinal pigment epithelium cells precedes the onset of phagocytizing by these cells of shed discs of the external rod segments.
