Abstract:Objective To investigate the expression of progesterone-induced blocking factor(PIBF) in serum of patient with recurrent spontaneous abortion (RSA)and to study their clinical significance.Methods The PIBF concentrations in serum of 56 RSA patients were measured by enzyme-linked immunosorbent assay(ELISA).64 normal pregnant women in the first trimester who wanted to abort were controls. Results PIBF concentrations in serum of RSA were significantly was lower than those in normal control group (P<0.05).Conclusion PIBF was related to RSA, The changes obviously decrease of expression of PIBF in serum of RSA group maybe one of the important cause of RSA. |
