두충(잎, 껍질, 줄기)의 추출물이 DNCB로 감작된 4주령 BALB/c mouse 암컷에 유도된 접촉성 피부염의 억제효과를 조사하였다. 림프절, 비장 및 흉선의 무게는 두충 투여군이 DNCB 대조군보다는 낮게 나타났다. 두충 부위별 추출물을 투여한 군에서 귀의 무게는 두충 추출물의 농도가 높을수록 감소하는 경향을 보였으며, 대조군과 비교하여 무게에 함량 변화가 있었다. 두충의 부위별 추출물을 1,000 mg/kg 농도로 투여하면 귀의 무게는 대조군과 유사한 수준까지 낮아졌으며, 귀의 두께는 두충 추출물을 투여한 군에서 시간이 경과할수록 두께가 감소하는 경향을 나타내었다. MDA 함량은 DNCB 대조군과 두충 투여군을 비교하였을 경우에, 간 조직에서 차이가 나타나지 않았으나, 염증이 발생한 귀 조직에서는 차이가 나타났으며(p<0.05), NO 함량은 SW, ST 및 BT 그룹에서 염증이 억제되어 대조군과 마찬가지로 측정되지 않았다.

This study was performed to investigate the influence of dietray food from the three CHinese medicinal herbs(Mugwort, Dried organge peel and Duchung) on lipi d metabolism in rats. Male rats of Sprague-Dawley strain were divided into four dietary groups(Cellulose (CL), Mugwort(MW), Dried organge peel9OP), Duchung(DC)) after three weeks of hyperlipidemic dieting and were fed ad libitum each of the experimental diets for six weeks. The fiber sources of the experimental diets were prepared by drying and milling mugwort, orange peel, duchung and cellulose. Each of the Fiber sources was mixed into the diet to achieve 10g% levels of total dietary fiber. Levels of apparent fat absorption exhibited a significant decrease in the MW and DC groups. The OP group also showed a decreasing trend, but to a lesser extent. The levels of serum total lipid were not significantly different among the four experimental groups. Total serum cholesterol levels were significantly lower in the OP grop that in both the CM and MW group. Serum TG and LDL-cholesterol levels were significantly higher in the DL group than other groups. Serum HDL-cholesterol levels were significantly levels were significantly lower in the CL group than in the other groups. Total lipid and total cholesterol in liver were significantly higher in the CL group than in the other groups. Total lipid and total cholesterol in feces displayed a significantly increase in the MW and DC groups when compared with the CL group. The OP group also showed an increase compared to the CL group.

기존 두충차의 단점인 한약의 향미와 떫은맛이 완화된 두충혼합차를 개발하기 위하여 8월 자연건조시료에 방향성 식용식물인 꽃향유를 10, 20, 30 및 40%를 각각 첨가하여 관능검사 하였을 때 꽃향유첨가군 모두가 reference보다 낮은 기호도를 보였는데, 이는 꽃향유 자체의 독특한 향기 때문으로 여겨진다. 둥굴레차를 시료두충차에 10, 20, 30 및 40%를 각각 혼합하여 관능검사한 결과, 둥굴레 20, 30 및 40% 첨가군이 시료두충차와 reference보다 전반적인 기호도가 높게 나타났다(p＜0.01). 부드러운 향미를 지닌 둥굴레를 두충차에 첨가하면 차의 색의 강도가 완화되고 전반적인 기호도가 높아지므로 일반인이 음용하기 좋은 두충혼합차가 제조될 수 있다고 판단된다. 시판두충차, 시료두충차, 꽃향유첨가군 및 둥굴레 첨가군의 향미패턴을 전자코로 분석하였을 때, 시료두충차는 제1주성분값이 (-)값에 분포되어 있었으며, 둥굴레첨가군은 제1주성분값이 주로 －0.10과 ＋0.05사이에 분포하였고, 시판두충차는 제1주성분 값이 －0.05∼＋0.05에 분포하였다. 꽃향유 10% 첨가군은 제1주성분 값이 －0.03∼＋0.05부근에, 꽃향유 20∼40% 첨가군은 ＋0.10∼＋0.20 사이에 제1주성분 값이 분포되었다. 관능검사 결과와 전자코에 의한 향기패턴 분석결과를 종합해 보면, 전반적인 기호도가 좋은 둥굴레첨가군과 시판두충차는 제1주성분값이 －0.10∼＋0.05 사이에 분포되어 있었으며, 이 분포를 중심으로 전반적인 기호도가 낮은 두충차는 (－) 또는 (＋)쪽으로 치우쳐 분포하는 경향을 보였다.

국산 대용차 중 시판되고 있는 두충차와 감잎차의 향기성분을 연속증류 추출법으로 추출하여 GC-MS에 의하여 분석, 동정하였다. 두충차에서는 hydrocarbon류 3종, alcohol류 17종, ketone류 15종, aldehyde류 16종, acid류 8종, hetero 고리화합물류 8종과 phenol류 2종을 포함한 총 77종류의 향기성분을 확인하였다. 두충차에 많이 존재하는 ketone류(14.59%) aldehyde류(23.31%)와 hetero 고리화합물(16.71%)들은 두충차의 특징인 달콤하고 한약재에 가까운 향기에 기여한다고 생각된다. 감잎차에서는 hydrocarbon류 10종, alcohol류 17종, ketone류 11종, aldehyde류 13종, ester류 8종, acid류 6종, hetero 고리화합물 5종과 phenol류 1종을 포함한 총 71종을 확인 하였다. 감잎차에는 향기의 기여도가 낮은 hydrocarbon류의 함량(10.40%)이 두충차에 비해 많았고 alcohol류의 함량(25.57%)이 현저하게 많아 은은하고 순한 감잎차의 특유향에 기여한다고 생각된다.

Object : This study was designed to asses the effect of Kunnuetang and herbs on Mouse neuroblastoma 2a cells damaged by hypoxia-reoxygenation. Method : Mouse neuroblastoma 2a (N2a) cells were measured by MTT assay and LDH assay after 48h hypoxia and 6h reoxygenation. Mouse neuroblastoma 2a (N2a) cells were treated by Kunnuetang, Duchang and Daejo. Result : 1. Kunnuetang, was effective on LDH assay of hypoxia and reoxygenation. 2. Duchang and Daejo were generally effective on LDH assay of hypoxia and reoxygenation. 3. In MTT assay of hypoxia Kunnuetang was not effective. Duchung and Daejo were not generally effective on MTT assay, but in certain condition Herbs were effective. 4. In MTT assay of reoxygenation Kunnuetang and Daejo were not effective. But Duchung was effective in certain condition. Conclusion : The results suggest that Kunnuetang, Duchang and Daejo may have protective effect on vascular dementia and ad patient.

Eucommia ulmoides (Duchung) is commonly used for treatment of diabetes in Korean traditional medicine. However, the exact mechanism of its anti-diabetic effect has not yet been fully elucidated. In this study, the effect of E. ulmoides extract on glucose uptake was investigated in L6 rat skeletal muscle cells. E. ulmoides extract stimulated the activity of phosphatidylinositol (PI) 3-kinase that is a major regulatory molecule in glucose uptake pathway. Protein kinase B (PKB) and protein kinase C-${\xi}$ (PKC-${\xi}$), downstream mediators of PI 3-kinase, were also activated by E. ulmoides extract. We assessed the activity of AMP-activated protein kinase (AMPK), another regulatory molecule in glucose uptake pathway. Phosphorylation level of AMPK did not change with treatment of E. ulmoides extract. Phosphorylations of p38 mitogen activated protein kinase (p38 MAPK) and acetyl-CoA carboxylase (ACC), downstream mediators of AMPK, were not significantly different. Taken together, our results suggest that E. ulmoides may stimulate glucose uptake through PI 3-kinase but not AMPK in L6 skeletal muscle cells.

To prove the effect of Yukmijihwngwon(YMJHW) and Taeyoungjeon(TYJ) extract on the Meridian of Human body and Active oxygen experimentally, ORS & Free Radical of extract and precipitate of YMJHW and TYJ was measured. The results were summarized as follows; 1. TYJ extract, as a result of measuring QRIS, had a considerable effect on the function of pituitary gland, the 4th cervical vertebra and the 1 st lumbar vertebra. 2. TYJ precipitate, as a result of measuring QRIS, had a considerable effect on the function of liver, uterus, and vertebra. 3. YMJHW extract, as a result of measuring QRIS, had a considerable effect on the function of lung, adrenalin gland, bladder, prostate gland, ovaria, the 2nd cervical vertebra, the 3rd cervical vertebra, the 5th cervical vertebra, the 6th cervical vertebra, the 2nd lumbar vertebra, the 4th lumbar vertebra and the 5th lumbar vertebra. 4. YMJHW precipitate, as a result of measuring QRIS, had a considerable effect on the function of spleen, lung, kidney, adrenal gland, bladder, ovaria, the 2nd cervical vertebra, the 6th cervical vertebra, the 7th cervical vertebra, the 2nd lumbar vertebra, the 5th lumbar vertebra, sacrum, and knee joint. 5. As a result of measuring Free Radical, the level of TYJ is higher than YMJHW. It is thiut that's because of Duchung and roasted Gamcho. 6. As an order of QRIS levels, YMJHW precipitate is the highest, YMJHW extract is next, TYJ extract and TYJ precipitate. These results suggested that TYJ and YMJHW be usefully applied for suppressing of abnormal Meridian and noxious oxygen, preventing and curing all the disease.
