Abstract

DMBA (7,12-Dimethylbenz(α)antracene) is one of Polycyclic Aromatic Hydrocarbon’s form that is abundant on air pollution, i.e. automobile exhaust, cigarette smoke, and wood stoves. DMBA is metabolized in liver result in DMBA-DE. DMBA-DE is a free radical compound that has hepatotoxic effect. Broccoli contains flavonoid that has antioxidant effect. It can stabilize DMBADE radical compound. This research was

conducted to investigate the hepatoprotective effect of ethanolic extract of broccoli on the damage of rat’s liver cells induced by DMBA. This research used 30 white male rats that was divided into 6 groups: normal control (aquadest), positive control (DMBA) and the treatment groups(using brocolli ethanolic extract with dose : 250, 500, 1000, and 2000 mg/kgBB). The treatment was given for 7 days followed by single-dose DMBA 15 mg/kgBB induction in the 8 th day. Histological appearance of liver cells were examined on the 12 th day. Data were analyzed by using Kruskal Wallis test followed by Mann Whitney. The result showed that there was a significant difference among the groups with p<0.05. In conclusion, there were some differences of hepatoprotective effect of broccoli ethanolic extract on the histologically damage of rats liver cells induced by DMBA.
