Efek Antioksidan Jamur Tiram Putih pada Kadar Malondialdehid dan Kepadatan Permukaan Sel Paru Tikus yang Terpapar Asap Rokok

Abstract

Cigarette smoke-free radicals can cause lipid peroxidation and pathological changes in lung cells. This effect could be prevented by highly active metabolite in Pleurotus ostreatus such us fenol, ascorbid acid, selenium, and ergothiene. This study aimed to analyze the effect of the Pleurotus ostreatus extract on the levels of malondialdehyde (MDA) and surface density (S/V) after exposure to cigarette smoke. The research used completed randomized design and á-tocopherol was used as control group. The dose of Pleurotus ostreatus ethanol extract was 250 mg/kg body weight and cigarette smoke exposure was given in 30 minutes/day for 10 days by smoking pump. Malondialdehyde (MDA) level and lung surface density (S/V) were observed on day 11th. This research was done at Clinical Pharmacology Department, Hasan Sadikin Hospital on July 2009.The result showed that ethanol extract of Pleurotus ostreatus can prevent increasing level of MDA (0.4667+ 0.22295 nm/mL), as good as that of á-tocopherol(0,7467+ 0,24089 nm/mL). Ethanol extract also prevented the reduction of lung S/V (0.62283+0.4793) and it's effect was better from á-tocopherol (0.54683±0.39832), p=<0.05. In conclusion, our data shows that etanolic extract of Pleurotus ostreatus is a strong antioxidant that have better effect than á-tocopherol in preventing oxidative damage of cigarette smoke
