The interleukin 10 (IL-10) contents in the uterus was assayed by ELISA. The results revealed that the IL-10 level was significantly decreased in the LPS-induced abortion group of mice compared with the controls. Use of pentoxifylline, or a combination of Radix scutellariae and Rhizoma atractylodis reversed the LPS effects: bringing down the fetal resorption rate, and enhancing the IL-10 level significantly. The study indicates that the anti-abortive effects of PXF and the combination of Radix scutellariae and Rhizoma atractylodis are closely related to up-regulation of the Th2 cytokine IL-10 at the maternal fetal interface.展开更多

Methods: The expression of the cytokines and the adhesion proteins was assessed using immunohistochemistry and immunoblotting. Results: None of the cytokines studied was present in the human testis, but CD99 and CD106 (VCAM-1) strongly were expressed in all the testes investigated. CD99 was present in the interstitial tissue of the human testis as well as in the Sertoli cells. The identity of the CD99+ interstitial cells is unclear. CD106 (VCAM-1) was present in Leydig cells as well as the basal parts of the Sertoli cells in the seminiferous tubules. In immunoblotting, CD99 was demonstrated at molecular ratios of 46-57 (kD). This is a novel isoform of the molecule. Conclusion: The human testis produces both CD99 and CD106 and as CD106 mediates cell binding to lymphocytes, it is possible that the human Leydig cells adhere to lymphocytes like the rodent Leydig cells.
