MORPHOLOGICAL CHANGES IN THE LUNG VESSELS OF LABORATORY RATS 1 HOUR AFTER ADMINISTRATION OF LEIURUS MACROCTENUS SCORPION VENOM

Abstract:

One hour after the introduction of Leiurus macroctenus scorpion venom, significant morphological changes were observed in the vessels of the lungs of rats. Stagnant capillaries, petechial hemorrhages, perivascular edema and destruction of vascular membranes were noted. The formation of stasis and blood clots was observed. Analysis of semi-thin sections showed a narrowing of the lumen of arterioles, folding of the internal elastic membrane and a decrease in vascular permeability. The morphometric parameters of blood vessels indicate a tendency to decrease their diameters compared to the parameters of the control group of animals.

Keywords:
