title: The Effect of Simvastatin on Pulmonary Damage in Experimental Peritonitis in Rats.
abstract: Statins are widely used in the treatment of hyperlipidemia, as they inhibit cholesterol synthesis. They also have anti-inflammatory, antioxidant, immunomodulatory, and positive endothelial-functional effects. It is hypothesized that simvastatin ameliorates pulmonary damage secondary to peritonitis in rats. Forty Wistar albino rats were divided into four groups. In sham group, laparotomy was the standard procedure. In simvastatin group, simvastatin was given perorally before laparotomy. In sepsis group, peritoneal sepsis was constituted by cecal ligation and puncture technique. In sepsis + simvastatin group, the procedures of simvastatin and sepsis groups were applied together. After sacrification at the 72nd hour, tissue samples from lungs were harvested for histopathological examination, wet and dry weight measurements, and tissue culture, tissue malondialdehyde, and nitric oxide tests. Blood samples were taken for C-reactive protein and whole blood count. While the malondialdehyde levels were found to be significantly higher in sepsis group, nitric oxide levels were found to be significantly lower in simvastatin + sepsis group. Alveolar hemorrhage was highest in simvastatin + sepsis group. There was no difference for C-reactive protein, leukocyte levels, and histopathological examination between any groups. The ratios of wet and dry lung weights were higher in simvastatin-given groups. Simvastatin has no positive effect in terms of lung dysfunction on experimental sepsis model. For a better understanding of the effects of simvastatin on lung injury in peritoneal sepsis, experimental models of longer duration that enable to search the effects of simvastatin beyond 3 days will be more useful.
