Blood supply of rat heart in normal condition and after sidnocarb treatment
Abstract
The aim of the research was to investigate the changes of vascular bed of rat heart in the normal condition and under sydnocarb treatment. The materials of our research were 22 rats, which were contained in the conditions of vivarium. By both anatomical and histological methods it was established, that rats have 3 types of supplement, and also delivering and feeding type of vessel branching. The delivering (87%) type of branching prevails in the walls of left ventricle of the heart and interventricular septa, where the diameter of vessels was relatively less, and the amount of branches was 3-4, that suggest the higher intensity of exchange of matters. The feeding type of branching (64%) prevails in the right ventricle and interatrial septa, where the amount of branches of the first order of branching was from 6 to 9. On early stages (to 3 days), after sydnocarb introduction, the change of vascular bed at the level of arteries and veins was accordingly the increase of their diameter on 10% and 27%.
