[Autoradiographic experiments on the cochlear capsule of the rabbit (author's transl)].

By means of autoradiography metabolic exchange on the molecular level is demonstrated. Mucopolysaccharides and proteins of the intercellular substance are incorporated in the same manner. The interglobular spaces however are excluded from metabolic turnover and do not show radioactivity. The adjacent cells resembling cartilage cells incorporate like osteocytes. Comparing the way of incorporation to cartilage cells of other areas of the otic capsule we find support of Manasse's theory that the cells of the globuli ossei of the adult orginate from cartilage cells.
