[Method of electron autoradiographic study of RNA synthesis in gastric gland cells]

A method of electron microscope autoradiographic investigation of gastric mucosa pieces obtained by clinical gastrobiopsy and incubated with uridine-5H3 was suggested. Comparison of the preparations with electron microscope radioautographs prepared after the administration of uridine-5H3 into the organism and with the results of control treatment with RN-ase permitted the authors to conclude that the method proposed reflect the RNA synthesis in the gastric gland cells.
