This study was proposed to investigate the effects of water extract of aged black garlic on ethanol induced hangovers in rats. Male Sprague-Dawley rats weighing $180{\pm}10\;g$ were divided into the following three groups; control, 130 mg/kg, and 260 mg/kg of aged black garlic extract. Aged black garlic was administered orally 30 min before and 30 min after ingestion of 40% ethanol (5 g/kg, B.W.). The rats were killed 24 hr after ethanol treatment, and blood was taken from the caudal artery at 1, 3, and 5 hr to test for ethanol or acetaldehyde in the serum. Groups that were administered aged black garlic extract pre- and post-alcohol consumption showed a significant decrease in ethanol levels in the blood at 1, 3, and 5 hr. The acetaldehyde concentrations decreased in both 130 mg/kg and 260 mg/kg groups that were administered aged black garlic extract pre- and post-alcohol consumption. The activities of alcohol dehydrogenase seemed to be unaffected, although the aged black garlic showed slightly higher activities of acetaldehyde dehydrogenase in pre- or post-alcohol consumption. The aspartate aminotransferase (AST) activity in the serum, elevated by ethanol, was decreased by administering a high dosage of aged black garlic extract, but resulted in no significant change in serum alanine aminotransferase (ALT) activity. These results concluded that aged black garlic extract can reduce hangover syndrome through the elevation of ALDH.

본 연구에서는 숙취용 음료를 개발하기 위하여 알코올을 투여한 흰쥐를 대상으로 흑마늘 추출물 130 mg/kg과 260 mg/kg을 각각 40% 알코올(5 g/kg, B.W.) 투여 30 분 전과 30 분 후에 경구 섭취시키고 1, 3 및 5 시간 동안 경시적으로 혈액 중의 알코올 및 아세트알데히드 농도와 간조직 중의 alcohol dehydrogenase (ADH) 및 acetaldehyde dehydrogenase (ALDH)의 활성과 간지표 효소인 alanine aminotransferase (ALT) 및 aspartate aminotransferase (AST)의 활성을 측정하였다. 알코올 투여 30 분 전에 흑마늘 추출물을 경구 섭취시켰을 때 혈 중 알코올의 농도는 시간 경과에 따라 급격하게 감소하였으며 알코올 투여 후 5 시간 경과 시 알코올 투여 대조군에 비하여 흑마늘 추출물 투여군이 28.5%로 감소하는 경향을 나타내었다. 또한 혈 중 아세트알데히드의 농도는 알코올 대조군에 비하여 흑마늘 추출물 투여군이 매우 감소하였다. 알코올 투여 30 분 후 흑마늘 추출물을 투여한 것은 알코올 투여 30 분 전의 실험군과 비슷한 경향을 나타내었다. 간 조직중의 ADH 활성은 정상군과 흑마늘 추출물 투여군 모두 큰 변화는 찾아 볼 수 없었으나 ALDH의 활성은 약간의 차이를 확인할 수 있었다. 혈청 ALT, AST 활성은 대조군과 흑마늘 추출물 간에 유의적인 차이는 나타내지 않았으나, 흑마늘 추출물의 섭취가 간 기능에 나쁜 영향을 미치지 않는 결과로 보아 안전성이 있다고 사료된다.
