The morphology of the microcirculatory bed of the liver during experimental inhalation of hydrochloric acid vapors

The aim of the study was to investigate changes in the hepatic vessels of small diameter under the influence of exogenous intoxication caused by respiratory way. Experiments were carried out on 16 rabbits of the chinchilla breed, which were divided equally into 4 groups. The first group included the control animals whose vascular structures were considered intact. The second group included the animal liver preparations which were studied on the 10th day of the experiments, and the III group animals were investigated on the 30th day of the experiment. The animals included into the IV group were killed on the 60th day of the experiment and preparations of the left lobe of their livers were investigated. It was found that on the 10th day of the experiments in the left lobe of the liver of the studied animals, there was an increase in the number and magnitude of the diameter of the vessels of the microcirculatory bed. On the 30th day of the experiments, on the contrary, the number of functioning hemocapillaries and their diameters are decreased. By the end of experiments of the phenomenon of a reduction of the microcirculatory bed in a liver were even more aggravated.
