BACKGROUND: We aimed to evaluate the microbiological and immunological effects of tissue plasminogen activator (tPA) in a rat model of peritonitis.
METHODS: Twenty-four male Wistar albino rats were divided equally into three groups. Peritonitis and thereafter laparotomy and partial omentectomy were performed in all rats. The control group (C) had no further treatment. The antibiotics group (A) received metronidazole and ceftriaxone. The antibiotic and tPA group (A+T) received the same antibiotics as well as tPA. For microbiological and immunological analysis, blood samples were obtained at the 24th hour, and peritoneal fluid samples were obtained at the 24th and 72nd hours. On the fifth day after surgery, all rats were sacrificed, and the macroscopic findings of the peritoneal cavity were recorded.
RESULTS: The mean number of intraperitoneal abscesses was significantly higher in the control group and the lowest in the two-treatment group (A+T). The levels of cytokines were not significantly different between groups. Giving tPA reduced the number and sizes of the abscesses with no significant difference in inflammatory response.
CONCLUSION: In this experimental peritonitis model, it can be postulated that tPA decreased abscess formation without exaggerating the inflammatory response.
