ABSTRACT
The study is focused on the observation of alkaline and acidic phosphatase activity in the glandular cells of uterine endometrium in puerperal ewes after exposure to polychlorinated biphenyls. Ewes of Slovak merino breed (n=25) divided into 2 groups were included in the experiment. The animals in the experimental group (n=14) and control group (n=11) were euthanised on day 17, 25 and 34 postpartum. The ewes in the experimental group were given per os capsules of the chemical preparation Delor 105 of domestic proveniance containing polychlorinated biphenyls (PCB) for a period of 30 days. This preparation is equivalent to the foreign preparation Aroclor 1254. A dose of 100 µg/kg of Delor 105 was given to the animals of the experimental group. These animals were euthanised on day 17 postpartum (n=4) i. e. 5 days from the end of a 30-day period of application; on day 25 postpartum (n=5) i.e. 17 days from the last application of PCB; on day 34 postpartum (n=5), which was equivalent to day 28 from the last application. The ewes from the control group were euthanised on day 17 (n=3), day 25 (n=4) and on day 34 (n-4) postpartum. When evaluating alkaline phosphatase (ALP) activity in the glandular cells of the endometrium in the control group, a statistically significant increase (P
