[The adaption growth of the heart in the higher (experimental autoradiographic researches in rats) (author's transl)].
There was examined the influence of the age on the development of a compensatory hypertrophy of the heart in 4 to 16 month old masculin Wistar-rats autoradiographically. The valuation took place at various times after stenosing of the aorta and application of 3H-thymidine separatly in both ventricular walls by counting of the nuclei of the marked muscle- and connective tissue cells of the heart and their mitosis. For the connective tissue cells computation of the 3H-thymidin- and of the mitotic index. Determination of the body- and heart weight.
