영문 초록

In this study we examined the effects of water extract of garlic on carbon tetrachloride-induced liver injury, and demonstrated increased beneficial enzyme and anti-oxidant activity as well as histopathological changes (by Hematoxylin-Eosin (H&E) staining, Trichrome staining, and TEM examination), and showed that the treatment was dose-dependent and safe. A total of 42 male Sprague-Dawley rats were divided equally (n=7) into six groups. To induce hepatotoxicity in these subjects, carbon tetrachloride diluted in an equal volume of olive oil was intraperitoneally administrated at 0.5 ml/kg (0.20 g/kg/day) once a day for five days. Water extract of Korean-grown garlic was administered via a stomach sonde once a day, 5 days a week, for a total of 4 weeks. Groups received 0.35 g/kg (E1), 0.70 g/kg (E2), or 1.40 g/kg (E3), with the dose adjusted for body weight. Administration of garlic extract resulted in positive physiological effects in terms of reduced oxidative stress and toxicity, and induced functional changes in the liver. Comparing the subject groups (E1, E2, E3) administered different doses of garlic extract, the importance of morphological analysis in further studies is emphasized, because morphological changes indicating hepatotoxicity could occur, even though beneficial enzyme activities were found to be elevated.
