TNF and peritonitis: In an experiment to study the effect of NSMP on the ability to induce cytokine production, when co-cultured with immunocompetent cells obtained from peritoneal exudate on a mice model of peritonitis, it was revealed that when co-cultured pro-inflammatory exudate, with a high content of neutrophils obtained on the first day, with NSMP, there was a significant decrease in TNF-a production.
