EMBRYOGENESIS, LEUKOCYTIC PROFILE AND LIVER MORPHOLOGY OF PREGNANT RATES UNDER THE ACTION OF CITRIC ACID
The article presents the results of studies on the effects of citric acid on the female’s body. The studies were performed on white laboratory rats of the Wistar line, which at the age of 3 - 3.5 months with a body weight of 192 - 210 g were divided into two groups of 4 individuals in each. The animals of the experimental group were fed by citric acid at a concentration of 80 mg/l of drinking water during the period physiological and puberty, fertilization and pregnancy. A control group of female rats was fed by water. The animals had free access to drinkers and food. Indicators of embryogenesis, leukocyte profile of blood and body weight of animals, weighting factor, histological changes of the liver were determined.
Female rats were found to have no abortions or premature births, however, the number of corpora lutea of pregnancy decreased by 19.2%, although there was no significant difference in control. The number of implantation sites per female was significantly lower by 28.8%. The mortality rate of embryos was 15.8%, which is 3.8 times higher than in intact animals. Regarding white blood cells, the analysis of the results indicates a tendency to increase the percentage of eosinophils in 2 times in the relation to the animals in the control group on the background of a probable increase in leukocytes by 42.4%.
The applied dose of citric acid caused certain changes in the macro- and microstructure of the liver. It is macroscopically established that under the influence of citric acid the organ is slightly enlarged, sluggish consistency and changed its color from light red to light brown. The relative weighting factors of the liver are probably higher in the relation to the control (52.12 ± 8.16 g/kg vs 43.38 ± 1.96 g/ kg).
The results of morphological studies indicate a partial violation of the lamellar structure of the organ in the centro-lobular region, which is due to turbid swelling of the cytoplasm of hepatocytes. In most cells, the contours are blurred, the cytoplasm is poorly stained, their nuclei are weakly basophilic, and hepatocytes with a lysed nucleus in a necrobiosis condition also occur. However, among dystrophic altered cells are clearly isolated hepatocytes with a uniformly colored basophilic cytoplasm, nucleus, rich in chromatin, which indicated the activation of reparative processes. Kupffer cells in this area are mostly round, located in the lumen of the sinusoid. Therefore, occurs a violation of lipoprotein complexes of cells and increase the permeability of cell membranes, which is reflected in the development of protein dystrophy with varying degrees of severity. Activation of reparative processes of hepatocytes is also determined.
