CHANGES IN THE INDICES OF NONSPECIFIC RESISTANCE OF AN ORGANISM IN MODELING DISTURBED REPARATIVE REGENERATION OF SHIN BONES

The problem of regeneration of bone structure and joint cartilage is one of the priority programs of scientific research. Regulation of bone formation at the damage is carried out by complex set of factors. A reflection of the regeneration processes is the dynamics of blood parameters, among which are the indicators of inflammatory reaction of the organism, and condition of phagocytosis system. One way to control the severity of impaired reparative regeneration is the analysis of immunological tests of the first order. The aim of our study was to investigate nonspecific resistance of the organism for any breach of reparative regeneration of bone in the lower leg. The study was performed on rabbits "Chinchilla" which simulated the breach of the terms of reparative regeneration. We assessed leukocyte profile and indicators of phagocytosis in experimental animals. Status of the phagocytic activity of blood neutrophils was evaluated on the following parameters: phagocytic index, phagocytic number, nitroblue tetrazolium test, the concentration of circulating immune complexes. We found broken shin bone reparative regeneration of rabbit at fiftieth day of observations is accompanied by leukocytosis with increased segmented neutrophils and a decrease in lymphocytes, inhibition of phagocytosis, and violation of the elimination of circulating immune complexes

Effect of single intake of exogenous hepatocytes growth inducer on the indices of non-specific resistance under conditions of postresection liver injury

HGF is one of the factors taking part in regeneration and recovery of liver after injury. The article is dedicated to the study of influence of single HGF intake on the indices of non-specific immune response in rats after 70% liver resection in the early postoperative period. Research was conducted on 42 six-months white male Wistar rats of 250-300 g. It was revealed that level of segmentonuclear neutrophils and lymphocytes in the group with HGF intake stand at normal level on the 2nd day and normalizes to the 11th day that testifies to the decrease of inflammatory response. Increased level of leukocytes and monocytes is registered in the group with HGF intake. Also integrity of non-specific resistance in the early postoperative period on the 2nd day is registered. Suppression of phagocytosis indices with preservation of functional activity of phagocytes was registered to the 11th day
