The proportion and the distribution of T-lymphocytes,null lymphocytes and acid phosphatase positive lymphocytes of the peripheral blood and endometrium in pregnant mice [Gebe farelerde perifer kan ve endometriyum dokusunda T-lenfosit,null lenfosit ve asit fosfataz pozitif lenfositlerin oran ve daǧi{dotless}li{dotless}mlari{dotless}]

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 mm2),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 mm2) 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 mm2). 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.
