Effect of monocyte chemotactic protein-1 on the intraperitoneal adhesion formation.

In order to study the role of monocyte chemotactic protein-1 (MCP-1) in the intra-peritoneal adhesion formation, 23 infertile patients undergoing laparoscopic operation were divided into two groups: experimental group including 12 patients with intra-peritoneal adhesion and control group including 11 patients without intra-peritoneal adhesion. Peritoneal fluid (PF) and peritoneum were collected from these patients during laparoscopic examination. The expression levels of MCP-1 protein and MCP-1 mRNA were detected by using enzyme-linked immunosorbent assay (ELISA) and dot blot analysis method respectively. It was found that the levels of MCP-1 protein in PF of the patients with peritoneal adhesion were significantly higher than in the control group (0.44 +/- 0.11 ng/ml vs 0.19 +/- 0.09 ng/ml respectively, P < 0.01). The level of MCP-1 mRNA in the peritoneum of the patients with peritoneal adhesion was significantly higher than in the control group (48.61 +/- 3.72 vs 19.87 +/- 2.54 respectively, P < 0.01). It was suggested that MCP-1 might play a role in the adhesion formation, and chemotactic cytokines expressing in the peritoneal mesothelial cells might be take part in the process.
