CHARACTERISTICS OF FUNCTIONAL ACTIVITY OF SURFACE EPITHELIUM OF REPRODUCTIVE ORGANS OF COWS WITH HAEMORRHAGIC ENDOMETRITIS

One of the problems in livestock still stays a reproduction of animals. For further intensification of the industry the crucial role is assigned for enhancing reproductive function.

These modern scientific literature suggests the presence of significant specific features of structural and functional organization of epithelium of the reproductive organs of animals. So far remain unclear especially the structure and function of epithelial tissue in different parts of female reproductive system of various animal species [1]. However, with seemingly a sufficiently large number of scientific publications on the physiology and pathology of the reproductive system of a large rogatogo cattle, there is still no formulated concepts, defining the specific significance of epithelial tissue in the physiology of reproduction, the etiology and pathogenesis of diseases of the reproductive system and fertility of animals [2,3,4,5,6].

Thus, our research into diseases of the endometrium in normal and pathological conditions, undoubtedly relevant. Material for histological, cytometric studies morphometric studies were genitals from clinically healthy (control group) and cows to be culled diagnosed with hemorrhagic endometritis, and 3 animals with hemorrhagic endometritis (experimental group), cows that were kept in the same conditions in the agricultural formations Kostanay region.The studies found that the wall of the uterine horns of cows suffering hemorrhagic endometritis, thickened in volume throughout. Their length is shortened in the gaps often are patches of small diameter.

When analyzing the characteristics of the surface epithelium cytometric right uterine horn Vågå clinically healthy cows set to medium size plane show mercy epithelial cells is 157,167±33,080 mkm². Nuclei size, on average, is 43,914±12,635 mkm². And in the surface epithelium cells predominate small size with small nuclei. Nuclear protoplasmic ratio, average, 0,279 ± 0,024. Linear analysis revealed a generation of epithelial cells, with a central location modality.

Nuclear protoplasmic ratio of the surface epithelium of the left uterine horn is 0,268±0,033. Basically, the surface epithelium presented cells having medium expressed functional activity. The median area of the surface epithelium cells of the left uterine horn is 54,880±5,482 mkm². Basically, cells are small. Size of the kernel of the left uterine horn epithelium is 15,535±3,520mkm². At the same time revealed two equivalent generation of cell nuclei. Nuclear protoplasmic ratio of the surface epithelium of the left uterine horn cow is 0,280±0,035. When linear analysis revealed one generation NPR modality with a central location.

Thus, analyzing the cytometric characteristics of the surface epithelium of the right uterine horn of patients with hemorrhagic endometritis cows was installed reducing the rates of epithelial area and their nuclei in comparison with those in clinically healthy cows. Comparing the results of the functional activity of the surface epithelium of the right uterine horn animals in pathology and normal, it was found an increase in the functional activity of the surface epithelium in hemorrhagic endometritis.

Area of epithelial cells and nuclei of the surface epithelium of the left and right uterine horns in hemorrhagic endometritis is reduced compared with the same period in clinically healthy animals. Analysis of the functional activity of the surface epithelium of the uterine horn sick cows showed an increase in the coefficient compared to the same period in clinically healthy cows.
