본 연구에서는 streptozotocin으로 당뇨를 유발시킨 횐쥐에게 methanol로 추출하여 분획한 참마의 $H_2O$ 분획물을 경구투여하고 selenium은 식이로 보충하여 당뇨시 14일간 혈당과 지질대사에 미치는 영향을 실험하여 다음과 같은 결과를 얻었다. 당뇨대조군은 당뇨로 인한 대사상의 변화로 정상군과는 다른 대사적인 차이를 나타내었다. 전 실험 기간 중 횐쥐의 체중변화는 정상군에 비해 당뇨실험군 모두에서 유의적으로 감소되었으며 DJT-Se군에서 다른 당뇨실험군보다 적은 양의 체중감소를 보였다. 참마와 Se 보충식이에 따른 식이효율도 DJT-Se군에서 유의적인 차이는 아니었지만 다른 당뇨실험군에 비해 높았다. 장기 의 무게를 체중 100g당으로 환산하였을 때 간장과 신장의 무게는 정상군보다 유의적으로 비대해졌으며 비장은 당뇨실험군 모두에서 정상군보다 무게가 낮게, 췌장은 높게 나타났다. 혈장 포도당 수준은 당뇨실험군 중 DJT-Se군에서 유의적으로 낮아졌으며 인슐린의 함량 수준은 당뇨실험군 간의 유의적인 차이를 보이지 않았으나 DJT-Se군에서 약간 높았다. 혈장단백질 수준은 당뇨대조군에 비해 당뇨실험군 모두에서 높게 나타났다. 혈장 지질 수준에 미치는 영향을 보면 혈장 cholesterol의 경우 당뇨대조군과 당뇨실험군 간의 큰 차이는 없었으나 당뇨실험군에서 낮은 경향을 보였다. HDL-cholesterol 수준은 모든 당뇨실험군에서 높게 나타났다. 중성지방의 경우는 DJT-Se군과 Se군에서 유의적으로 낮은 수준이었다. 유리지방산 함량은 정상군과 당뇨실험군 사이에 차이를 보이지 않았다. AST와 ALT 활성도는 군 간에 큰 차이를 보이지 않았으나 당뇨대조 군에 비해 DJT군에서는 유의성을 보였다. 본 연구 결과 참마나 Se를 독립적으로 섭취하는 것 보다는 병용하여 보충하는 것이 항산화 작용의 상승효과를 보여주어 고혈당과 지방대사산물에 작용하여 혈당강하효과를 보일 것으로 생각된다. 참마의 혈당강하에 영향하는 생리활성성분과 Se보충에 의한 대사적인 변화에 대하여 더 구체적인 생화학적인 연구가 이루어져야 될 것으로 여겨진다.

An experiment was conducted using 20 male buffalo calves to study the effect of vitamin E and selenium supplementation on their immune response and plasma ${\alpha}$-tocopherol and selenium status. These buffalo calves (10-12 months old, average body weight $75.30{\pm}2.20 $ kg) were randomly allotted to four treatments on the basis of their body weights and were fed on wheat straw and concentrate mixture to meet their nutrient requirements of 500 g/d body weight gain. The buffalo calves were fed either a control diet (neither supplemented with Se nor VE) or diets supplemented with Se at 0.3 ppm (+Se), DL-alpha tocopheryl acetate at 300 IU (+VE), and both DL-alpha tocopheryl acetate at 300 IU and Se at 0.3 ppm (+Se+VE). These experimental diets were fed for 180 days. Blood samples were collected at day 0 and subsequently at 45 day intervals up to 180 days of experimental feeding to monitor plasma ${\alpha}$-tocopherol and Se concentrations. To assess humoral immune response, all calves were sensitized with formalin inactivated Pasteurella multocida antigen at 135 days of experimental feeding and blood was collected on 0, 7, 14, 21 and 28 days post vaccination (DPV) to measure antibody production using indirect ELISA. Cell mediated immune response of calves was assessed after 180 days of experimental feeding by in vivo delayed type hypersensitivity (DTH) reaction using phytohaemaglutinin-P (PHA-P) as a mitogen. Results revealed that feeding of VE and Se improved the plasma levels of these nutrients. Plasma levels of Se were affected by supplementation of both VE (p<0.001) and Se (p<0.001); however, no interaction ($Se{\times}VE$) was observed. Supplementation of Se improved the humoral immune response (p<0.008), whereas, VE showed a tendency towards improvement in cell mediated immune response (p<0.064). It was concluded that vitamin E and Se supplementation improved the status of these micronutrients and humoral immune response in buffalo calves.

In order to investigate the effect of selenium (Se) on the liver damage, metallothionein synthesis and hepatic antioxidative detoxification system in cadmium(Cd) administered rats. Sprague-Dawley male rats(60\\5g) were divided into two diet groups, depending on with (CdS groups) or without (Cd groups) 0.5ppm Se supplementation and fed experimental diets ad libidum for 4 weeks. And then each group was again subdivided into five groups, depending on injection number of Cd, i.e., 0, 1, 2, 3, and 4 times of 2.5mg Cd/kg of body wt once a day. Hemoglobin concentration, hematocrit values, superoxide dismutase, glutathione peroxidase and glutathione S-transferase activite were decreased progressively with increasing number of Cd injection, but increased by the supplementation of Se. The reduced form of glutathione (GSH) contents in blood and liver and vitamin E content were decreased and oxidized form (GSSG) increased in Cd groups, but these of Se supplemented groups were not very different from controls. Cd reduced liver vitamin E content which was not restored by Se supplementation. Liver lipid peroxide values were elevated with increasing doses of Cd, but Se supplementation reduced these elevated levels. Accumulation of metallothionein in liver and kidney was increased with increasing number of Cd injection, but Se did not affect on them. Histological examination revealed that lysosomes were significantly increased and mitochondria and Golgi apparatus were enlarged by Cd, however, these changes were reduced by Se. It was concluded that Se administration promoted antioxidative detoxification and alleviated peroxidative damage in rat liver by Cd.

Postprandial hyperglycemia plays an important role in the development of type 2 diabetes and complications associated with the disease such micro-and macro-vascular disease. The present study investigated the effect and action mechanism of a ethanolic extract from the Schizandra chinensis(SC-E) on hypeglycemia in vivo and in vitro. In vitro, SE-E demonstrated a potent inhibitory effects on ${\alpha}-amylase$ activity ($IC_{50}$ : 4 ${\mu}g/ml$). Its inhibition on ${\alpha}-amylase$ was determined to be competitive type. Oral administration of SE-E markedly lowered plasma glucose levels in non-fasted streptozotocin induced diabetic rats (45 mg/kg BW). In addition when it was orally administrated to rats with starch (2g/kg BW), SC-E (50 and 100 mg/kg BW) significantly suppressed the increase of blood glucose levels after starch loading . These results suggest that some edible plants merit further evaluation for clinical usefulness as anti-diabetic drugs.

Objectives: There were only small studies about the difference of the quality of life depending on blood stasis. We investigated that the blood stasis made the differences of quality of life. Methods: We recruited the participants stratified according to age and gender. The participants were assessed independently by two Korean medicine doctors more than 7 years of clinical experiences whether or not with blood stasis. And they responded at the questionnaire associated with blood stasis and SF-36. The analysis was done with IBM SPSS Statistics (ver. 21). Results: Total 101 participants were checked for with/without blood stasis. 40 participants were accord in the diagnosis with blood stasis by two doctors. Two researchers coincided in diagnosis with non-blood stasis in 42 participants. 19 participants showed the discrepancy between the assessment of blood stasis and they were classified as non-blood stasis. The mean age in group of blood stasis was $44.07{\pm}11.65$, it was not shown the significant difference comparing non-blood stasis group. The subscale of physical function (PF), role-physical (RP), bodily pain (BP), general health (GH), vitality (VT), mental health (MH) and role emotional (RE) in SF-36 were significantly low in the group of blood stasis. Blood test including biochemistry, fibrinogen, prothrombin time and D-dimer was not in abnormal range according to blood stasis without CRP. Conclusions: The patients that diagnosed of blood stasis showed the bad physical health status, and partially bad mental health. It is necessary to investigate whether Korean traditional treatment for blood stasis would be made improvement for quality of life. Moreover, the standardization of diagnosis on blood stasis would be needed.

Sensitising cancer cells and at the same time desensitizing normal cells is a double task in cancer management. Agents which can combat the debilitating side effects of cancer therapeutics and simultaneously synergize with anticancer agents in specifically targeting cancer cells are needed. Selenium, a proven anticarcinogen, gains due importance in terms of its efficacy to combat the side effects of cancer therapy. This study is a comparative analysis of the chemoprotective effects of selenium compounds, methyl selenol (generated from organic selenomethionine (5mmol/L ; METase 40U/L)) and sodium selenite (inorganic form)($30{\mu}M$) in peripheral blood human lymphocytes exposed to cisplatin and mitomycin. Biochemical alterations occurring in many cells during apoptosis include loss of plasma membrane phospholipid asymmetry, DNA fragmentation, and activation of caspase-3. The present study demonstrated that the selenium metabolite and selenite are efficient in protecting lymphocytes undergoing DNA damage and exerted their activity by reducing caspase 3 expression. Interestingly organic methylselenol (MeSe) was found to offer more protective effects compared to inorganic selenite (SeL), by reducing the induction of apoptosis by the cytotoxic agents. This suggests that MeSe and to a lesser extent selenite might have potential for assessment in clinical trials and could be considered as strong candidates in pharmacogenomics or in the nutriprotective arena.

Excessive drinking causes 'alcohol hangover' within 8-16 hours. The cause of 'hangover' has not been elucidated exactly until now, but it is reported that it is caused by the creation of blood ethanol and acetaldehyde as ethanol metabolites. In this study vinegar extract of wood (VE) or OC-1, to which the powder extract of green tea leaves extract is added, was administered to the rats 30 minutes before the oral administration of ethanol (3 g/kg) and the blood ethanol and acetaldehyde concentration was measured in order to evaluate the efficacy of the beverage material for detoxification. As a result, the blood ethanol concentration in the group of the VE-1(vinegar crude extract) and VE-2 (double diluted solution) is statistically lower (P,0.05) than the exclusive alcohol administered control group. The blood acetaldehyde concentration of all groups of VE and OC-2, which is the double dilution of OC-1, is statistically low after 7 hours following ethanol administration. Especially, the AUC value of OC-2 group is statistically low compared to the control group. Accordingly, it indicates the conclusion that VE and OC-1, reducing the blood ethanol and acetaldehyde concentration which are two leading factors of 'hangover' after drinking, and worthwhile to be developed as beverage materials to eliminate 'hangover'.
