Abstract
To examine the effect of overdosed functional food in liver-injured patients, we tried to investigate the dose effect of Allium sativum L. (also called garlic) extract on rats with CCl4-induced liver damage, by comparatively examinating the hepatic function of each group. 42 male Sprague-Dawley rats were selected and divided equally (n=7) into normal, control, positive control, and three experimental subgroups (E1, E2 and E3), respectively. For each kg of body weight, hepatic injury was induced by intraperitoneal administration of $0.5\;m{\ell}$ (0.20 g/kg/day) $CCl_4$, which was diluted in equal amount of olive oil, once a day on every other day for total 5 times. Hot water extraction was performed using domestically cultivated organic garlics, and the obtained extract was injected by sonde, once daily during 4 weeks, to each experimental subgroups by different dosage of 0.35 g/kg(E1), 0.70 g/kg(E2), 1.40 g/kg(E3), respectively. Results showed that the injection of garlic extract positively influenced the physiological activation which lowered the oxidative stress, changed the toxicity, and functionally improved the hepatic condition. Comparing the dose effect between the three experimental subgroups (E1, E2, E3), results of the maximal-dosed subgroup (E3) showed less significance compared with the lower-dosed subgroups(E1 and E2), which seems to resulted from the (increased) toxicity of garlic.
본 논문은 기능식품의 과용에 따른 간질환 환자에게 미치는 영향을 알아보기 위해, 마늘열수추출물의 용량을 달리하여, 사염화탄소에 의한 랫드의 간 손상을 유발하여 기능학적검사를 통해 간장에 미치는 용량의 중요성을 알아보았다. 실험동물은 Sprague-Dawley 종 웅성 랫드로 하여 정상군, 대조군, 양성대조군, 실험군 E1, E2, E3 군으로 나누어 각 군당 7마리씩 총 42마리를 이용하였고, 실험동물은 체중 당 사염화탄소 $0.5\;m{\ell}$ (0.20 g/kg/day)를 olive oil에 동량 희석하여 1일 1회 격일 간격으로 총 5회 복강 내 투여하여 간 손상 유발한 후 국내에서 유기농 재배한 마늘을 열수 추출하여 각 실험군에 체중 당 0.35 g/kg(E1), 0.70 g/kg(E2), 1.40 g/kg(E3)를 일일 1회, 주 5일, 4주간 위존데를 사용하여 투여하였다. 실험의 결과로 마늘추출물의 투여가 생리적 기능 활성에 긍정적인 작용을 하여 간장에서 산화스트레스를 감소시키고 독성 증감작용 및 기능학적 변화를 확인하였고, 용량에 따른 실험군(E1, E2, E3) 간의 비교에서 고농도 투여군(E3)에서는 마늘독성의 영향 때문에 E1, E2보다 긍정적인 효과를 덜 보였다.
