$Nokyangbotang^{TM}$ (NYBT) is a kind of powerful food for health and have been drunk at a oral dose of 80 ml (99.5 mg) three times per day: It has not been well studied about the anti-fatigue and hepatoprotective activity. In this experiments, we evaluated pathophysiologically the effect of NYBT on swimming time in mouse and hepatoprotective activity in rats intoxicated with carbon-tetrachloride. NYBT was nontoxic in orally acute toxicity test ($LD_{50}$, 320 ml/60 kg): a nontoxic food in more four times of one-shoot dosage (80 ml) to human. Weight-loaded forced swimming test was carried out to measure the swimming time of mice with a 4% load of body weight in plastic cylinder (diameter $10{\;}cm{\;}{\times}{\;}height{\;}20{\;}cm$) on water bath at $25^{\circ}C$, and the anti-fatigue activity represented the ratio of swimming time of experimental group to that of control group. NYBT had dose-dependent anti-fatigue activity Mice administered NYBT at a dose of 320 ml/60 kg once daily for 5 days could swim about two times more than control. Hepatoprotective activities of NYBT were examined by the determination of malonedialdehyde (MDA) and pathological survey in liver and liver function test of rat intoxicated with $CCl_4$ at i.m. dose of 2 ml/kg once daily for 7days. NYBT decreased dose-dependently thiobarbituric acid reactive substance: Oral administration of NYBT at a dose of 20 ml/60 kg was $38.51{\;}{\pm}{\;}3.02$ nmol MDA/g of tissue, that of 80 ml/60 kg was $33.76{\;}{\pm}{\;} 1.84$ nmol MDA/g of tissue, and that of 320 ml/60 kg was $32.87{\;}{\pm}{\;}1.90$ nmol MDA/g of tissue as compared with control group ($43.61{\;}{\pm}{\;}2.85$ nmol MDA/g of tissue). All rats administered NYBT at a dose of 320 ml/60 kg were survival as compared with 40% survival of control animals, and GPT activity of rats administered NYBT at a dose of 80 ml/60 kg was decreased as compared with control. In histopathological survey, NYBT improved slightly the fatty changes of hepatocytes around centrilobular area. These results suggest that NYBT has anti-fatigue and hepatoprotective activity in rats and mice.

본 연구는 투어마린 소재와 전기적인 방전을 통해 물의 성질을 변화시킨 투어마린이온활성수를 이용하여 간보호 효과, 비만 예방 효과, 숙취제거 효과를 확인하기 위해 시행되었다. 고지방식이로 비만을 유도한 ICR 마우스에서 투어마린이온활성수를 급이한 실험군은 정수물을 급이한 대조군과 비교하여 사료섭취량이 비슷하고 음수량이 더 적었지만 체중증가는 대조군에 비하여 억제되어 13주에는 유의한 차이를 보여줌으로써 비만 예방 효과를 나타내었다(P<0.05). 사염화탄소로 간독성을 유발시킨 생쥐를 이용하여 간보호 효과를 관찰한 실험에서, 실험군의 aspartate aminotransferase (AST)와 alanine aminotransferase (ALT)는 대조군과 비교하여 평균적인 차이를 나타내었으며, 간의 조직학적 관찰에서 괴사를 비롯한 병리학적 병변이 감소한 것으로 나타났다. S-D rats을 이용한 숙취 실험에서는 실험군이 대조군에 비해 혈중알콜농도가 유의하게 낮았으며(P<0.01), 알콜 대사와 관련된 항산화 효소인 glutathione-S transferase (GST)는 활성이 증가한 것으로 관찰되었고(P<0.05), 간기능 지표인 AST와 ALT는 상대적인 감소현상을 보였다. 이와 같은 결과는 투어마린이온활성수의 음용이 동물의 항산화 체계에 영향을 미침으로써 간조직을 보호하고 알콜 분해를 향상시킨 것으로 판단되며, 그 결과 숙취해소에 어느 정도 효과가 있을 것으로 판단된다. 투어마린이온활성수의 효능과 관련된 기전은 아직 과학적 검증에 어려움이 있으나, 물에 전달된 투어마린의 원적외선에너지나 전기적 영향으로 인하여 물분자의 결합력과 분자 구조 또는 클러스터의 크기에 변화를 일으켰기 때문으로 판단된다. 사용된 투어마린이온활성수는 음용안전성이 확보된 물로서 효과적인 기능수로 개발될 가능성을 가지며, 유효성과 관련된 기전은 더 연구될 필요성이 있다.

The present experiment was performed in order to know the therapeutic effect of laserpuncture and aquapuncture with methionine on recovery in artificially induced hepatic damaged rats by carbon tetrachloride. The animals were divided into control, laserpuncture and aquapuncture groups. The changes of serum enzyme activities(ALT and AST), serum total protein contents, protein fractions(ALB and GLB) and A/G ratio were examined before and after application of laserpuncture and aquapuncture. In change of serum ALT activity, recovery with treatment in laser and aquapuncture groups was more rapid than that of control. The significant decreased value was shown on 3rd(P < 0.05) and 7th day(P < 0.01) after treatment in laserpuncture group and on 7th day(P < 0.05) after treatment in aquapuncture group. In addition, significance was detected on 2nd day(P < 0.05) between laserpuncture and aquapuncture groups. In change of serum AST activity, recovery with treatment in laserpuncture and aquapuncture groups was more rapid than that of control. The significant lower values on 7th day(P<0.01) in aquapuncture groups. In addition, significant low value was detected on 7th day(P < 0.05) in aquapuncture group comparing with that of laserpuncture group. The change of serum TP contents showed similar pattern in control, laser and aquapuncture groups. The significances were detected on 7th day(P < 0.05) in both experimental groups. In addition, significant high value was detected on 2nd day(P < 0.05) in laserpuncture group comparing with that of aquapuncture group. The change of serum ALB content with treatment in laser and aquapuncture groups was more rapid than that of control. The significant high value was shown on 2nd(P < 0.01), 5th(P < 0.05) and on 7th day(P < 0.01) in laserpuncture group. In addition, significant high value was detected on 3rd day(P<0.01) only in aquapuncture group comparing with laserpuncture group. The change of serum GLB content showed similar pattern among groups. The significant low values were detected on 2nd day(P < 0.05) in aquapuncture group. In addition significant high value was detected on 5th day(P < 0.01) only in laserpuncture group comparing with that of aquapuncture group. In change of A/G ratio laser and aquapuncture groups showed higher values than that of control. The significant high values were detected on 1st day(P < 0.Of) and 2nd day(P < 0.05) in laserpuncture group, and on 1st day(P < 0.05) and 2nd day(P < 0.01) in aquapuncture group. In addition, significant high value was detected on 5th day(P < 0.05) in aquapuncture group comparing with that of laserpuncture. Considering above findings collectively, it was considered that both laserpuncture and aquapuncture were effective; aquapuncture was more effective than laserpuncture for recovery of hepatic damage.

Objectives : This study investigated cellular-protective effects of Nardotidis seu Sulculii Concha water extract (NSCE) against oxidative stress induced by arachidonic acid (AA)+iron or tert-butylhydroperoxide (tBHP). Methods : In vitro, MTT assay was assessed for cell viability, and immunoblotting analysis was performed to detect expression of AMP-activated kinase (AMPK) signaling pathway and autophagy related proteins. In vivo, mice were orally administrated with the aqueous extract of NSCE of 500 mg/kg for 3 days, and then injected with CCl₄ 0.5 mg/kg body weight to induce acute damage. The level of liver damage was measured by serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) analysis. Results : Treatment with NSCE inhibited cell death induced by AA+iron and tBHP. NSCE induced the phosphorylation of AMPK, and this compound also induced the phosphorylation of LKB1, an upstream kinase of AMPK, and Acetyl-CoA carboxylase (ACC), a primary downstream target of AMPK. NSCE increased the protein levels of autophagic markers (LC3II and beclin-1) and decreased the phosphorylation of mammalian target of rapamycin (mTOR) and simultaneously increased the phosphorylation of unc-51-like kinase-1 (ULK-1) in time-dependent manner. Conclusions : NSCE has the ability 1) to protect cells against oxidative stress induced by AA+iron or tBHP. NSCE 2) to activate AMP-activated protein kinase (AMPK), and 3) to regulate autophagy, an important regulator in cell survival.
