Abstract
BACKGROUND: Renal failure in cirrhotic patients is a severe complication and endotoxemia might be involved. We investigated the effect of endotoxin on renal function of cirrhotic rats and the potential protective role of N-acetylcysteine (NAC). MATERIAL/METHODS: Hepatic cirrhosis was generated in a rat model by carbon tetrachloride. Both cirrhotic and normal rats were insulted by endotoxin intravenously, while another cirrhotic group was pre-treated with NAC. Blood urea nitrogen (BUN) and creatinine were assayed eight hours later. The changes in serum tumor necrosis factor-a (TNF-a) were assayed by ELISA. The histological changes in the kidney were observed after hematoxylin and eosin staining. RESULTS: Endotoxin increased the BUN and... (More)
BACKGROUND: Renal failure in cirrhotic patients is a severe complication and endotoxemia might be involved. We investigated the effect of endotoxin on renal function of cirrhotic rats and the potential protective role of N-acetylcysteine (NAC). MATERIAL/METHODS: Hepatic cirrhosis was generated in a rat model by carbon tetrachloride. Both cirrhotic and normal rats were insulted by endotoxin intravenously, while another cirrhotic group was pre-treated with NAC. Blood urea nitrogen (BUN) and creatinine were assayed eight hours later. The changes in serum tumor necrosis factor-a (TNF-a) were assayed by ELISA. The histological changes in the kidney were observed after hematoxylin and eosin staining. RESULTS: Endotoxin increased the BUN and creatinine levels in both normal and cirrhotic rats, with a much higher elevation in the latter group. TNF-a concentration was also increased by endotoxin; the changes are positively correlated with BUN and creatinine. NAC pretreatment significantly attenuates the effects of endotoxin on BUN, creatinine and TNF-a levels in cirrhotic rats with no improvement in systemic toxicity symptoms. There were no obvious histological changes in the kidney of these animals. CONCLUSIONS: Hepatic cirrhosis increased the sensitivity of renal function to endotoxemia, which may be protected by NAC.
