Morphometric aspects of remodeling of the arterial bed of the testicles in post- resection portal and pulmonary hypertensions.

Objective: Aim: To perform a morphometric analysis of the features of vascular remodeling of the arterial bed of the testicles in post-resection portal and pulmonary hypertension.

Patients And Methods: Materials and Methods: The testes of 54 white rats were studied, which were divided into groups: 1st included 16 intact animals, 2nd - 20 rats with pulmonary hypertension, 3rd - 18 individuals with post-resection portal hypertension. Postresection pulmonary hypertension was modeled by right-sided pulmonectomy.

[THE STRUCTURE OF THE ILEUM AFTER THE RESECTION OF LIVER PARENCHYMA].

The ileum was morphologically examined in 45 sexually mature white male rats, which were divided into 3 groups: I group included 15 intact animals, II - 15 rats, in which 31.5% of the liver parenchyma was removed, III - 15 animals after resection 58,1% of liver parenchyma. Euthanasia of rats was performed by bloodletting under the conditions of thiopental anesthesia 1 month after the beginning of the experiment.
