Investigation of lymphocyte subpopulations and hypersensitivity skin tests during the menstrual cycle and pregnancy. 1982

S Agarwal, and H S Shukla, and M Verma, and S C Gupta, and K Mukherjee

Cell-mediated immune responses were examined during the menstrual cycle of 10 healthy females and in 90 pregnant females, 10 for each month of gestation, and in 10 females 2--4 weeks after normal delivery. Lymphocytes and their subpopulations and PPD hypersensitivity skin tests were investigated. The lymphocyte subpopulation T-cells showed statistically significant depression at the time of ovulation (P less than 0.01) and during the entire period of gestation (P less than 0.001) with recovery in the post-partum period. There was borderline PPD skin response during pregnancy which became positive after parturition. These changes were demonstrated to be specific to conception but the exact mechanism of the T-cell depression is not known. There was a corresponding rise in the B-cell count.

D007958 Leukocyte Count The number of WHITE BLOOD CELLS per unit volume in venous BLOOD. A differential leukocyte count measures the relative numbers of the different types of white cells. Blood Cell Count, White,Differential Leukocyte Count,Leukocyte Count, Differential,Leukocyte Number,White Blood Cell Count,Count, Differential Leukocyte,Count, Leukocyte,Counts, Differential Leukocyte,Counts, Leukocyte,Differential Leukocyte Counts,Leukocyte Counts,Leukocyte Counts, Differential,Leukocyte Numbers,Number, Leukocyte,Numbers, Leukocyte
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008598 Menstruation The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.
