title: [Functional morphology of the supravascular layer of the myometrium].
abstract: In the experiment performed on 15 rabbits, action potentials as a group of spikes and separate pick fluctuations have been revealed electrophysiologically in the round ligament of the uterus and the proper ligament of the ovary. In various parts of the myometrial supravascular layer and in the ligaments of the uterus under normal conditions and at leiomyoma nicotinamidedinucleotide-tetrazolium reductase (NADH), nicotinamidedinucleotide-phosphate reductase (NADPH) and alkaline phosphatase activity has been determined both in the myometrial supravascular layer and in the ligaments of the uterus. At leiomyoma NADH activity is elevated, and that of NADPH--decreased in comparison with that in the intact organ. Capillary density in various parts of the myometrial supravascular layer at leiomyoma of the uterus does not noticeably++ differ from that under normal conditions. The data obtained prove the conclusion on a morphofunctional unity of the myometrium and the ligaments of the uterus. By the aggregate of a higher parameters of the enzymes investigated in the area of the posterior part of the isthmus of the uterus, a conclusion is made on a specific functional importance of this part in comparison with others.
