[A structural analysis of the myocardium in 2-month-old rats cultivated in vitro from the viewpoint of tissue homeostasis].
Ventricular myocardium of 6 mature male Wistar line rats (100-129 g of body weight) cultured in vitro was exposed to the effect of vasopressin, oxitocin, dophamin and norepinephrine. The cell structures were observed by means of light microscopy. Nonapeptides and monoamines were found to cause cardiomyocyte hypertrophy and hyperplasia Vasopressin and oxytocin stimulate the endotheliocyte and myocyte proliferation and interstitial fibrillogenesis. Adequate trophic conditions were created to maintain energetic and anabolic metabolism of the surviving, hypertrophic and reorganizing cardiomyocytes.
