【Abstract】 Objective To detect the changes of immune cells in mouse uterus induced by SA 30(a Con A binding glycoprotein isolated from bovine sperms), and then reveal the influence of SA 30 immunization on the development of early mouse embryos. Methods The CD4 +、CD8 + and CD57 + cells in uterus of SA 30 immunized or control female Kunming mice were detected by immunohistochemical method(LSAB). Results On 3 day of pregnancy, much more CD4 +、CD8 + and CD57 + cells occurred in the uterus of SA 30 immunized mice than those of the control mice. On the other hand, the positive cells were found both in the endometrium and myometrium of immunized mice, but only in myometrium of control mice. Conclusion SA 30 can induce the cell mediated immune responses in mouse uterus, which may be toxical to the early embryos.更多还原
