Morphometric aspects of studying the features of remodeling of atrial structures at postresection portal hypertension

Introduction. Removal of the left and right lateral lobes liver in white rats leads to postresection portal hypertension, which is characterized by dilation plethora hepatic vein, mesenteric veins, esophageal gastric veins anterior abdominal wall, splenomegaly, ascites multiorgan failure.
 Objective research: study features remodeling structures atria at hypertension histostereometrically.
 Materials research their discussion. The peculiarities were histostoreometrically studied 65 adult male rats, divided into 3 groups: 1- consisted 20 intact animals, 2 – 30 with was modeled removal liver, 15 animals failure. One month after start experiment, euthanized bloodletting under conditions thiopental anesthesia. Histological micropreparations used determine diameters cardiomyocytes atria, nuclei, nuclear-cytoplasmic relations, relative volumes cardiomyocytes, capillaries, stroma, stromal-cardiomyocyte, capillary-cardiomyocyte damaged cardiomyocytes. Quantitative indicators processed statistically.
 Results Histostereometrically, it found that hypertrophy atrial growth stromal structures, disorders tissue cellular structural homeostasis. revealed dominated atrium combination Conclusions. Postresection pronounced changes an increase volume morphological
