چکیده مقاله:
Ischemia/reperfusion injury (IRI) is caused by a sudden temporary impairment of the blood flow to the particular organ. The IRI of the kidneys is one of the main causes of acute kidney injury. A vigorous inflammatory and oxidative stress response to hypoxia and reperfusion usually happens as IRI consequences that disturb the organ function. The current study aimed to investigate the effect of antagonizing toll-like receptors (TLRs) effects by lipopolysaccharide obtained from Rhodobacter sphaeroides (LPS-RS) on this critical condition. In total, ۲۸ adult male Wistar rats were divided into four groups (n=۷) as follows: the sham group which underwent only laparotomy; control group that underwent laparotomy and IRI induction; vehicle group which was similar to the control group plus vehicle treatment, LPS-RS group that was similar to the control group but was pretreated with ۰.۵ mg/kg of LPS-RS. The results of the current research showed that LPS-RS reduced interleukin-۱β, interleukin-۶, tumor necrosis factor α, and ۸-isoprostane levels, compared to the control IRI group. However, LPS-RS did not ameliorate the kidney injury as manifested by the elevated levels of urea, creatinine, and neutrophil gelatinase-associated lipocalin. Taken together, the present study demonstrated that LPS-RS at the tested dose failed to offer a renoprotective effect against the IRI in rats.
