| 目的：探讨黑木耳多糖对内毒素（LPS）诱导大鼠急性肾损害的保护效应及可能机制。方法：健康雄性SD 大鼠，分为正常对
照组、LPS 组和黑木耳多糖组（LPS+ 黑木耳多糖）。根据分组，分别于复制模型前7 d 给予生理盐水或1%黑木耳多糖(15 mL/kg)预

| Objective:To investigate the role of Auricularia auricular-judae polysaccharide (AAP) in acute kidney injury induced
by lipopolysaccharide (LPS) in rats and to further explore the possible underlying mechanisms.Methods:Adult Sprague-Dawley rats
were randomly assigned into the control, LPS, and LPS plus AAP groups. Rats were injected with LPS (10 mg/kg, i.p.) to induce acute
kidney injury. Rats in the LPS plus AAP group were treated with AAP for 7 days before the induction of ALI. Blood urea nitrogen(BUN)
and creatinine (Cr) in serum were measured. Superoxide dismutase(SOD), total antioxidant capacity (T-AOC)activity and malondialdehyde
(MDA) level in kidney were measured. Pathological changes of kidney tissues were observed by HE staining.Results:The data
showed that treatment with AAP group significantly improved LPS-induced lung pathological changes, decreased the BUN and Cr level,
and reduced MDA level, increased the SOD, T-AOC activity.Conclusion:The results indicated that AAP has a protective effect on
LPS-induced acute kidney injury in rat. |
