    Abstract:
    BACKGROUND: PAF and its antagonists have been studied in the pathophysiology of various inflammatory conditions. This study investigates the effects of a platelet activating factor antagonist, lexipafant, on peritoneal adhesion formation and wound healing. MATERIALS AND METHODS: Forty-eight Wistar albino rats (300-350 g) were divided into four equal groups; adhesion-induced lexipafant (AL), adhesion-induced saline (AS), sham-operated lexipafant (SL), and sham-operated saline (SS). All rats underwent a midline laparotomy under sterile conditions. The anterior wall of the left uterine horn was scraped to cause hemorrhages in adhesion-induced groups. Following peritoneal injections of either saline or lexipafant, the incisions were closed in layers. On the 14th day, the rats were killed and adhesions were scored from 0 (none) to 4 (dense). Tissue samples from the adhesions and the left horn of uterus were examined biochemically for hydroxyproline content, and serum IL-6 levels were determined. RESULTS: The adhesion formation score was significantly increased in the AS group compared to the SL and AL groups (P < 0.001). The IL-6 levels of the AS group were higher than those of the other groups (P < 0.05). There was no significant difference in hydroxyproline content between groups (P > 0.05). CONCLUSIONS: Lexipafant plays a role in the prevention of adhesion formation without affecting wound healing.
