Nigella sativa prevented liver and renal tissue damage in lipopolysaccharide-treated rats

Abstract EN

Liver and renal dysfunction accompanying with the tissues’ oxidative damage has been reported to occur during Inflammation.

Nigella sativa has been well known for its antioxidant and anti-inflammatory effects.

The aim of this study was to investigate preventive effects of N.

sativa on liver and renal tissue damage in lipopolysaccharide (LPS)-treated rats.

The rats were divided into five groups: (1) control; (2) LPS (1 mg/kg, IP, for 10 days), (3–5) N.

sativa hydroethanolic extract (100, 200, or 400 mg/kg) before LPS.

Compared to LPS group, treatment by the extract decreased malondialdehyde, nitric oxide (NO) metabolites, and interleukin-6 while increased thiol content and superoxide dismutase and catalase activities in both renal and liver tissues.

N.

sativa extract also decreased serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase concentration, while it increased serum protein and albumin compared with LPS group.

In LPS group, serum blood urea nitrogen and creatinine were higher than control group.

The extract reversed the negative effects of LPS.

The results demonstrated that the N.

sativa prevented liver and renal tissue damage in LPS-treated rats.

It is suggested that the effects are due to its antioxidant and anti-inflammatory effects.
