Abstract

The bioactive effects of ethanol extracts from fly maggot (ME) on reduction of plasma lipids levels in rats fed high-fat diets (Expt. Ⅰ), and on liver function recovery of hepatotoxicity rats by intraperitoneal injection of carbon tetrachloride ($CCl_4$) or by orally administration of alcohol (Expt. II) were investigated. In expt. I, twenty seven, male rat SDS(sprague dawley strain) were randomly assigned to three treated groups, including normal control group, HF (group with high fat diets which have no extracts) and HFE (HF plus orally administered doses of ME extract at 5.0 mg/100g of body weight). In expt. II, forty five, male rats (SDS) were randomly assigned to each of the five groups: T1 (control), T2 (intraperitoneal injection of $CCl_4$), T3 (intraperitoneal injection of $CCl_4$ after orally administered with ME), T4 (orally administered with combination of ME and alcohol), T5 (orally administration of ME after orally administered with alcohol). There were significant decreases in plasma (TAG), (TC), (LDL-C) in the HFE group with orally administered doses of ME at 5.0 mg/100g of body weight, respectively, however, the (HDL-C) were significantly increased in HFE group as compared to HF group with high fat diets which have no extracts (p<0.05). The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), ${\gamma}$-glutamyl transferse(${\gamma}$-GTP) and bilirubin were highest in T2 or T3, and high in order T4 or T5, and lowest in T1 except for bilirubin which has same with T4, T5 (p<0.05). The high recovery of liver damage by $CCl_4$ from the light microscopic appearance was observed in rats (T3) with extracts, and also high in T4 than T5 by orally administrated with alcohol. In conclusion, the ethanol extracts from fly maggot may have a bioactive effects to prevent for human lipids disorder and alcoholic disease.
