  • This study was to investigate the hepatoprotective and anticirrhotic effects of Ganyeumilhobang(GIE) on the acute and chronic liver injury induced by various agents. Chronic liver injury induced by dimethylnitrosamine(DMN) ; a new experimental model for cirrhosis and the intraperitoneal injection of dimethylnitrosamine in the rat. Acute liver njury induced by carbon tetrachloride$(CCl_4)$ and D-galactosamine ; a experimental model for acute liver injury, the administration of $CCl_4$ and the intraperitoneal injection of D-galactosamine in the rat. The development of fibrosis and acute liver injury by the three prescriptions were examined by the chemical analysis of AST, ALT, prothrombin time and hydroxyproline. The results obtained were as follows. 1. The increasing level of hydroxyproline volume induced by DMN in mice was decreased by the oral administration of GIB. 2. The degree of histological fibrosis and hepatic inflammatory cell infiltration induced by $CCl_4$ decreased by the oral administration of GIB. 3. The increase of senun AST and ALT of mice with acute liver damage induced by $CCl_4$ and D-galactosamine was inhibited by the administration of GIB. 4. The prolongation of prothrombin time(seconds) of mice acute liver damage induced by $CCl_4$ was shortened by the oral administration of GIB. 5. The liver of mice was hepatectomized partial1y after the oral administration of GIB. The mitotic index(% of nuclei), weight of liver, contents of protein, RNA and DNA synthesis of the liver tissue were increased by the oral administration of GIB.

  • 인류는 질병에 대한 예방 및 치료에 주로 합성 의약품을 사용하여 왔으나 근래에 이르러 여러 가지 합성 의약품의 부작용 또는 독성이 밝혀짐에 따라 세계적으로 천연자원으로부터의 의약품 개발이 활발히 추진되고 있다. 한편, 우리나라를 위시한 동양에서는 오랜 시일을 통하여 많은 식물을 치료제로 사용하여 왔으나 약화학적 및 약리학적 검토 자료는 지금에 와서 많이 도출되고 있으며 다양한 연구가 이루어지고 있는 실정이다. 본 연구에서는 해양생물로부터 생리활성을 검색할 목적으로 검은 밀복으로부터 제독처리하여 추출, 정제한 검은 밀복 간유를 대상으로 항피로효과, 간기능에 미치는 영향 및 poloxamer-407로 유도되는 고지혈증에 대한 효과를 검색한 결과, 다음과 같은 결론을 얻었다. 첫째, 식품위생학적 안전성 여부를 조사하기 위하여 검은밀복 간유의 정제품을 mouse assay로 그 잔류 독성을 조사한 결과 모두 무독하였다. 둘째, 생쥐를 유영하게 하여 사망하는 시간을 측정하여 본 결과 정상 생쥐에서는 사망시간보다 복어간유를 용량별로 2주일간 경구투여하였을때 사망 시간은 용량 의존적으로 증가되었다. 셋째, 간장해의 유발 약물로 사염화탄소 및 D-galactosamine(GaIN)을 사용하여 복어로부터 추출한 복어간유를 투여한 결과 사염화탄소 및 GaIN을 투여하였을 때 혈중 AST, ALT 및 SDH의 활성이 정상군에 비하여 현저히 증가되던 것이 복어간유의 전처리로 현저히 억제되었다. 넷째, 혈청 중 중성지방 및 total cholesterol의 함량은 정상군에 비하여 poloxamer-407의 투여로 증가되던 것이 복어간유를 용량별로 투여함으로써 현저히 감소되었다. 한편 poloxamer-407로 유도된 고지혈증의 실험동물의 bleeding time이 복어간유의 투여로 연장되었으며 plasma clotting time도 증가되었다.

  • In this study, we investigated the hepatoprotective effects of aged black garlic (ABG) in rodent models of liver injury. ABG inhibited carbon tetrachloride-induced elevation of aspartate transaminase (AST) and alanine transaminase (ALT), which are markers of hepatocellular damage, in SD rats. D-galactosamine-induced hepatocellular damage was also suppressed by ABG treatment. However, ABG does not affect the elevation of alkaline phosphatase (ALP), a marker of hepatobilliary damage, in rats treated with carbon tetrachloride or D-galactosamine. We also examined the effect of ABG on high-fat diet (HFD)-induced fatty liver and subsequent liver damage. ABG had no significant effect on body weight increase and plasma lipid profile in HFD-fed mice. However, HFD-induced increase in AST and ALT, but not ALP, was significantly suppressed by ABG treatment. These results demonstrate that ABG has hepatoprotective effects and suggest that ABG supplementation might be a good adjuvant therapy for the management of liver injury.

  • Background: Panax ginseng has a wide range of biological activities including anti-inflammatory, antioxidant, and immunomodulatory functions. Wild ginseng cambial meristematic cells (CMCs) were obtained from P. ginseng cambium. This study examined the protective mechanism of wild ginseng CMCs against $\small{D}$-galactosamine (GalN)-induced liver injury. GalN, a well-known hepatotoxicant, causes severe hepatocellular inflammatory damage and clinical features similar to those of human viral hepatitis in experimental animals. Methods: Hepatotoxicity was induced in rats using GalN (700 mg/kg, i.p.). Wild ginseng CMCs was administered orally once a day for 2 wks, and then 2 h prior to and 6 h after GalN injection. Results: Wild ginseng CMCs attenuated the increase in serum aminotransferase activity that occurs 24 h after GalN injection. Wild ginseng CMCs also attenuated the GalN-induced increase in serum tumor necrosis factor-${\alpha}$, interleukin-6 level, and hepatic cyclooxygenase-2 protein and mRNA expression. Wild ginseng CMCs augmented the increase in serum interleukin -10 and hepatic heme oxygenase-1 protein and mRNA expression that was induced by GalN, inhibited the increase in the nuclear level of nuclear factor-kappa B, and enhanced the increase in NF-E2-related factor 2. Conclusion: Our findings suggest that wild ginseng CMCs protects liver against GalN-induced inflammation by suppressing proinflammatory mediators and enhancing production of anti-inflammatory mediators.

  • The effect of some peptides on hepatoprotection and cecal fermentation against D-galactosamine (GalN)-treated rats was studied. In acute hepatic injury tests, serum alanine aminotransferase (ALT), aspartate aminotranferase (AST), and lactic dehydrogenase (LDH) activities were remarkably increased after injection of GalN. However, potato and soybean peptides significantly decreased GalN-induced alterations of serum ALT and AST activities. Hepatic thiobarbituric acid-reactive substance (TBARS) concentration in GalN-treated groups fed potato and soybean peptides was significantly lower than that in GalN-treated control group. Hepatic glutathione level in the GalN-treated group fed potato peptide was significantly higher than that in GalN-treated control group. Furthermore, cecal Lactobacillus level in GalN-treated groups fed potato and soybean peptides was significantly higher than that in GalN-treated control group, and cecal short-chain fatty acid concentrations in GalN-treated group fed potato peptide were significantly higher than in GalN-treated control group. These results indicate that potato peptide may improve the cecal fermentation and prevent the GalN-induced liver damage in rats.

  • This study was attempted to investigate the effect of 'Angelicae gigantis Radix extract (AG.EX.)' and 'Angelicae acutilobae Radix extract (AA.EX.)' on the activities of GOT, GPT and alkaline phosphatase (A1.P), the contents of total cholesterol in serum of $CCl_4$ and D-galactosamine intoxicated rats, and the weight change ratio of body, liver and spleen in $CCl_4-intoxicated-rats$ by administering the extract of 300 and 500 mg/kg P.O.. Significant test was performed by comparision with the biochemical values between intoxicated-control group and extract-administered group. The activities of s-GOT, s-GPT and the contents of total cholesterol elevated by $CCl_4-intoxication$ were significantly decreased in all dose (300, 500 mg/kg) of Angelicae gigantis Radix-water extract (AG.WEX.) and alcohol extract (AG.AEX), and Angelica acutilobae Radix-water extract (AA.WEX.) and alcohol extract (AA.AEX.), respectively, as compared with the control group. And administered group of 300 mg/kg showed more significant decreasing effect than 500 mg/kg, and more significantly decreased in water extract of AG.EX. and ethanol extract of AA.EX. But in the activities of s-A1.P. inhibition effect were significantly decreased only in a dose of 300 mg/kg of AA.WEX. and AA.AEX. The activities of s-GOT and s-GPT elevated by D-galactosamine were not decreased in all samples, as compared to intoxicated-control group. But the activities of s-Al.p was significantly decreased as compared with control groups, in all samples and administration of 300 mg/kg was more significantly decreased than 500 mg/kg. The contents of total cholesterol remarkably decreased than the normal groups by D-galactosamine intoxication was not recovered in all samples. The increasing rate of the body weight increased by $CCl_4-intoxication$ were not decreased than the $CCl_4-control$ group in all sample groups. The increasing rate of liver weight increased by $CCl_4-intoxication$ were significantly decreased in 300 mg/kg of AA.AEX.AG.WEX. and AA.WEX., respectively, as compared with $CCl_4-control$ group.
