사염화탄소로 섬유화가 유도된 흰쥐 간에서 털부처꽃 뿌리 추출물의 항산화 및 섬유화저해 활성

다국어 초록 (Multilingual Abstract)

Fifty percent ethanol extract of Lythrum salicaria Linne root (LSR) was tested in vitro on antioxidant activity, and furthermore was investigated on antioxidative and fibrosis protecting activities in CCL4-induced liver fibrosis rat model. Ratio of hepatic GSH/GSSG (reduced glutathione/oxidized glutathione) as bio-parameter of antioxidant level in CCL4 plus LSR-treated rats for 6 weeks significantly increased from 2.8- to 5.7-fold than that of CCL4-treated rats at p 〈 0.05. Thiobarbituric acid reactive substances (TBARS) contents in CCL4 plus LSR-treated rats ranged from 1.57- to 2.19-fold of normal rats and were lower than those in CCL4 plus silymarin-treated rats (1.78~2.46-fold of normal rats) (p 〈 0.05). Amounts of hydroxyproline of liver tissue showing the content of total collagen, a parameter of fibrosis, in CCL4 plus LSR-administrated rat livers were 4.9~8.8μg/mg (-47~-71%, compared with that in CCL4-treated rat livers (16.6μg/mg tissue), which were significantly lower than those in CCL4 plus silymarin-administrated rats being 8.4~11.7μg/mg (-30~-50%). This collagen reducing effect of liver tissue in CCL4 plus LSR-treated rats was supported by histological observation using microscopy assay. From the results, we conclude that the root of L. salicaria have efficient antioxidant potential and effective antifibrotic activities.
