title: [Ultrastructure of rat proximal renal tubular epithelium during substrate stimulation of cardiotrast secretion].
abstract: An electron microscope study was made of the epithelium of rat kidney proximal tubule, following a 3 day (three times a day) injection of cardiotrast in dose of 500 mg/kg, aimed to detect some morphological equivalents of the substrate stimulation of kidney tubular secretion of organic substances. Changes have been revealed in the ultrastructure of endoplasmic reticulum, ribosomal apparatus, and microbodies.
