Abstract

The relationship between the spontaneous electrical activities of paired fallopian tubes, and, accordingly, each of them with the uterine corpus, was studied by stepwise transections. The stability of rhythmogenesis of the left uterine horn was revealed in case of the both experimental conditions- when the right horn or the left horn itself was isolated. Transection of the right fallopian tube contributes to decrease in the values of such parameters of activity as the amplitude and rise-rate of action potentials (almost by 10 %) in the left fallopian tube. It has also been shown that the values of similar parameters of electrical activity were decreased in the uterine corpus after transection of the right (the amplitude - by 29.83% and the rise - rate - by 17.6%), then the left (by 36.67% and 16 % respectively) uterine horns.

Based on the results obtained in these experiments, we assume that the left uterine horn has a unique stability of automatism and, at the same time, it is in a certain functional relationship with the uterine corpus.
