    This study was performed to determine the effects of pregnancy on the activities of alpha naphthyl acetate esterase (ANAE) and acid phosphatase (ACP-ase) of the peripheral blood lymphocytes in pregnant Merino sheep. Peripheral blood lymphocyte percentages were also estimated. Periferal blood samples were taken from animals in six different gestational stages as non-pregnant control, in the first, the second, the third, the fourth and the fifth month of pregnancy. Each group was contained 20 animals. The lowest ANAE (+) lymphocytes percentage (63.5%) was determined in the first month of pregnancy whereas the highest null lymphocytes proportion (12.75%) was detected in the same gestational period. There were statistically decreases in the proportions of peripheral blood lymphocyte (42.9%) and the ACP-ase (+) lymphocytes (43.35%) in the last gestational stages. Although the posibble hormonal changes may cause the fluctuation of peripheral blood lymphocyte proportions in all gestational periods, the most distinctive changes were observed at the begining and at the end of the pregnancy. It was concluded that the data was obtained from this study was useful for understanding of the possible mechanisms of maternal tolerance.

    The proportion and the distribution of t-lymphocytes, null lymphocytes and acid phosphatase positive lymphocytes of the peripheral blood and endometrium in pregnant mice
    (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2014) Sur, Emrah; Oznurlu, Yasemin; Ozaydin, Tugba; Celik, Ilhami; Aydin, Ibrahim; Kadiralieva, Nariste
    This study was performed to determine the effects of pregnancy on the proportion of T-lymphocytes, null lymphocytes and acid phosphatase (ACP-ase) positive peripheral blood lymphocytes and the distribution of the mentioned cells in the decidua basalis region of endometrium in the pregnant mice. For this purpose, mice at 12-14 weeks of age were divided into four groups as non-pregnant control, and at the middle of the first, second, and the third week of the pregnancy, corresponding to early, middle, and late (3rd, 10th, and 17th days of pregnancy) gestational stages respectively (n = 6 for each group). The lowest T-lymphocytes percentage was determined at early and middle pregnancy in the peripheral blood (43.83%) and decidua basalis (10.83 number/0.1 mm(2)), respectively. There was a statistically significant increase in the proportions of the peripheral blood ACP-ase (+) lymphocytes (44.33%) at the mid-gestational period while the lowest ACP-ase positive lymphocyte numbers (5.50 number/0.1 mm(2)) in the decidua basalis was observed at early pregnancy. The highest null cell rates were found at early gestation either in the peripheral blood (11.50%) or in the decidua basalis (7.83 umber/0.1 mm(2)). The lowest percentage of peripheral blood lymphocyte (56.00%) was recorded at the early pregnancy. It was concluded that the number and the distribution of the lymphocyte, T-lymphocyte, null lymphocyte, and ACP-ase positive lymphocyte were affected by pregnancy although there were some differences among the gestational periods.
