Our results showed that in the control group, levels of measured inflammatory cytokines increase after peritoneal adhesion caused by the operation, and both concentrations of acetyl salicylate in treatment groups they reduce TNF-α levels after peritoneal adhesion after surgery, and the above studies show our results in reducing TNF-α anti-inflammatory cytokine, thereby reducing peritoneal adhesion Confirms after the operation. The gene discussed is TNF; the disease is peritoneal well differentiated papillary mesothelioma.
