Objective:To investigate the expression of interleukin-8 (IL-8) mRNA in villi,decidua and peripheral blood mononuclear cells (PBMCs) of patients with recurrent spontaneous abortion (RSA).Methods:The expressions of IL-8 mRNA in villi,decidua and PBMCs of 30 RSA patients,as well as 30 normal pregnant women were measured by semi-quatitative transcriptional polymerase chain reaction (RT-PCR). Results:In villi,the expression of IL-8 mRNA was significantly higher in RSA group than that in the control group. In de...
