[Morphometric parameters of hepatic lobule vessels in mice during the restorative period after leg injury].

The diameters of the hepatic lobule vessels (interlobular veins, central veins, interlobular arteries, intralobular sinusoidal capillaries, interlobular bile ducts) were been studied 3, 7 and 28 days after shin bones fracture in CBA mice (n=30). Most pronounced changes of morphometric parameters indicative of hemodynamic disturbances, were found 3 days after the trauma. The increase of the diameter of central, interlobulat veins and sinusoidal capillaries took place, together with the decrease of the diameter of interlobular arteries, which, probably, promoted the reduction of arterial blood supply.

[Microcirculatory bed and epithelial reproduction in avian liver at different stages of ontogenesis following a single exposure to hyperthermic conditions].

The aim of the present work was to study the reactive changes in avian (chicken) hepatic microcirculatory bed and epithelium following a single exposure to hyperthermic conditions at different stages of ontogenesis. Application of morphometric methods resulted in a demonstration of a unidirectional response of hepatic acinus vascular bed in embryonic period and after hatching of the birds, as well as differently directed effects of the mechanisms of cellular reproduction. In both experimental groups, heat shock results in the destructive changes in hepatic epithelium.

[Structural bases for the minimization of function of the proximal epitheliocytes of the nephrons in a single acute overheating of the body].

Morphological bases of functional potentialities of nephrons were studied in the experiment with 115 two-month rats under conditions of general momentary hyperthermia. The size of renal corpuscles tends to diminish. It is found that damages occur mainly in epithelium of the proximal parts of nephrons with disturbances in the reabsorption apparatus.

[Effect of thermal stress on the morphogenetic potencies of nephron epithelium].

Experiments on 46 male rats aged 6 months have been carried out to study the effect of thermal stress on biological potencies of the nephron epithelium with the use of the F. M. Lazarenko's method for cultivating organs and tissues in the body.
