MORPHOLOGICAL INTERACTION IN PLACENTOMA OF CATTLE DURING COMPLEXED PREGNANCY WITH ECLAMPSIA
It has been established that maternal and fetal parts of the placenta of cows with pregnancy complications with eclampsia are flattened, edematous, their total number is reduced to 83-91 pieces, compared with those during physiological pregnancy (91-121 pieces), where caruncles and cotyledons, as a rule have ellipsoid regular shape. A morphometric study of histopreparations showed that the height of the epithelium of crypts of caruncles of the maternal part of the placenta of cows during uncomplicated pregnancy was 9,54±0,05 μm, and during pregnancy complication with eclampsia, 6,35±0,02 μm (р≥0,05). Moreover, the relative size S of cotyledons' villus in clinically healthy cows was 40,4±1.46 µm, and with a complication of pregnancy with eclampsia 32,1±1,07, with a high degree of confidence (р≥0,01). The relative area of connective tissue of caruncles and cotyledons of the placenta occupied 39,0±1,07 µm of healthy animals, while in eclampsia it was 47,0±1,12 µm, the epithelium of crypts caruncles and vines of cotyledons looked almost the same, and the relative area of the vales of the cotiledons the fetal part of the placenta was within 16,6,±0,59 microns, with a high degree of confidence (р≥0,01) The number of diplocaryocytes with an apical surface on the chorionic villi per unit area of cotyledons during the physiological course of pregnancy is 8,5±2,1 and reduced with a complicated course of pregnancy with eclampsia to 2,8±0,84, (р≥0,01).
