  • Coronary heart disease (CHD) has been the number one killer in western society for a long time, and CHD in most instances is due to atherosclerosis. One of the earliest events in atherogenesis is the intracellular accumulation of lipids, particularly cholesterol esters, in the aortic intima. The lipids presumably came from the uptake of plasma lipoproteins, particularly from LDL. These foam cells were identified as being predominantly as macrophages. Currently, it is believed that oxidation of low density lipoprotein (LDL) might contribute to the generation of foam cells. An outcome of the oxidation hypothesis is that the consumption of antioxidants would be beneficial. In this study, Boldine, an alkaloid of Peumus boldus was tested for their antioxidant potency both in, in vitro oxidation system and in mouse models. Boldine decreased the ex-vivo oxidation of Low-density lipoprotein (LDL). In vivo studies were performed to study the effect of these compounds on the atherosclerotic lesion formation in LDL r-/- mice. Three groups of LDL r-/- mice (N=12 each) were fed an atherogenic diet. Group 1 was given vehicle and group 2 and 3 were given 1 and 5 mg of Boldine/day in addition to the atherogenic diet. The results indicated that there was a decrease in lesion formation reaching a 40% reduction due to Boldine compared to controls. The in vivo tolerance of Boldine in humans (has been used as an herbal medicine in other diseases) should make it an attractive alternative to vitamin E.

  • Daejowhan-gamibang(DJG) is used to prevention and treatment of cerebrovascular disease, heart disease, dementia, hyperlipdemia circulatory disturbance. Korean traditional herbal prescriptions and herb medicines in neuronal cells, which have been used for the treatment of stroke and brain diseases in Korean traditional medicine were screened to study the antioxidant effects and its mechanism. Daejowhan-gamibang water extract(DJGWE) was tested on their antioxidant activity using radical scavenging effects against ABTS. It showed significant antioxidant capacities at 50㎍ concentration. The antioxidant activity of DJGWE was determined in the different concentration (10㎍, 50 ㎍, and 100㎍). At the same time, the antiperoxidation effects was determined. Lipid peroxidation in brain homogenates induced by NADPH and ADP-Fe/sup 2+/ was significantly inhibited by DJGWE in vitro. DJGWE showed a potent antioxidant and antiperoxidative activity, further investigation, in vitro and in vivo, will be needed for the confirm of possibility as an antioxidant therapeutic agents and their optimal treatment of brain diseases in human. In searching the mechanism of antioxidant effects of DJGWE, it showed the inhibition of activity of JNK, p38, ERK and caspase 3 induced by hypoxia. So, DJGWE should be surveyed for the use of the potential therapeutic prescription for stroke and brain degenerative diseases such as pakinson's disease, dementia.

  • There have been growing interests in olive oil, which is attributed to the beneficial health effects of the Mediterranean diet. Numerous studies suggest that oleic acid, the major fatty acid in olive oil, may contribute to less incidence of coronary heart disease(CHD) in the Mediterranean area. Although the major effects of high monounsaturated fatty acid(MUFA) consumption on lowered plasma cholesterol are generally attributed to the consequential replacement of saturated fatty acid in diets, some studies have shown a modest cholesterol lowering effect of MUFA alone when it replaces dietary carbohydrate at an equal amount of energy. Furthermore, MUFA increases the level of the protective high-density lipoprotein cholesterol more than polyunsaturated fatty acid(PUFA) does when these two classes of fatty acids replace carbohydrates in the diet. It has been generally recommended that optimal dietary fat should be rich in MUFA, such as oleic acid, low in saturated fatty acids and provide adequate amounts of PUFA. However, no conclusive observations have been made yet mainly due to a difficulty in controlling the proportion of oleic acid without adjusting the levels of the other fatty acids to be constant, which could also affect plasma cholesterol levels. Recent findings also suggest that dietary PUFA results in higher tendency toward lipid peroxidation whereas with MUFA the susceptibility of low density lipoprotein to oxidative stress is reduced. More studies are needed to clarify the effects of MUFA on reducing the incidence of CHD.

  • Our preliminary study showed that genistein and daidzein improved blood glucose level in type 2 diabetic mice by enhancing the glucose and lipid metabolism. The objective of this study was to evaluate whether genistein and daidzein are associated with alterations in antioxidant defense mechanism of type 2 diabetic mice. Male C57BL/KsJ-db/db (db/db) mice and age-matched non-diabetic littermates (db/+) were used in this study. The db/db mice were divided into control, genistein (0.02%, w/w) and daidzein (0.02%, w/w) groups. The relative weights of liver, epididymal adipose tissue and perirenal adipose tissue were significantly higher in the db/db group than in the db/+ group, whereas heart weight was lower. The genistein and daidzein supplement did not affect the organ weights in db/db mice. The blood glucose level was positively correlated with superoxide dismutase (SOD, r=0.380, p<0.05) and catalase (CAT, r=0.345, p<0.05) activities and negatively correlated with glutathione peroxidase (GSH Px, r= 0.404, p<0.05) activity in erythrocyte. Therefore, the erythrocyte SOD and CAT activities were significantly elevated in the db/db group compared to the db/+ group and the GSH-Px activity was lowered. However, the supplementation of genistein and daidzein reversed erythrocyte CAT and GSH-Px activities in type 2 diabetic mice. In this current study, the SOD activities in liver, kidney and heart were significantly not different between the groups. The CAT and GSH-Px activities in liver and GSH-Px activity in kidney were significantly higher in the db/db group than in the db/+ group, while the CAT activity in kidney, CAT and GSH-Px activities in heart were lowered. The supplementation of genistein and daidzein significantly attenuated the changes of CAT and/or GSH-Px activities in liver and heart. The supplementation of genistein and daidzein elevated GSH levels in kidney and heart compared to the db/db control group. The lipid peroxide levels in liver, kidney and heart were significantly lowered in the genistein and daidzein supplemented groups compared to the db/db control group. These results suggest that genistein and daidzein might be beneficial for the prevention of type 2 diabetic complication via suppressing changes of antioxidant enzymes activities with simultaneous reduction of lipid peroxidation.

  • The present study examined the physiological effects of isoflavone-rich bean sprout on the lipid metabolism of hyperlipidemic rats. Experimental hyperlipidemia was induced by the AIN standard diet with 0.5% cholesterol,9.3% lard and 0.2% sodium cholate in SD rats. Experimental groups consisted of normal control, hyperlipidemic control, 1% or 5% bean sprout powder-supplemented groups, and 0.2% soybean isoflauone extract-supplemented group. Four weeks feeding of isoflavone-rich bean sprout powder or isoflavone extract resulted in a significant lowering of plasma cholesterol and lowering tendency of triglyceride levels. The levels of lipid peroxidation products in the kidney and heart tissues were also lowered by the supplementation of bean sprout powder or isoflavone extract. The activities of hepatic glutathione peroxidase and catalase were increased by the supplementation of bean sprout powder or soybean isoflavone extract. Plasma concentration of vitamin A was significantly raised in the group fed 0.5% bean sprout powder. The results of the study showed that the beneficial effects of isoflavone-rich bean sprout on lipid metabolism of hyperlipidemic animals were comparable with those of soybean isoflavone extract. The positive effect of bean sprout in improving lipid metabolism might be due to the combined action of isoflavone and dietary fiber.

  • Motherwort (Leonurus sibiricus L), a hemp nettle (Labiatae) plant, grows about 1.5${\~}$2 m high spontaneously to wildness in Korea, China, Japan, and other Asian place. Its medical applications includes women's uterine disease, urination, bloody stool, bloody urine, and hemorrhoids. It's also effective for high blood pressure, heart stimulation, and anti-cancer activity. We first prepared chlroform and methanol extracts of motherwort and then they were fractionated using water, $30\%$ methanol, $60\%$ methanol, and $100\%$ methanol, respectively. Each fractionates is assayed for free radical scavenging activities against DPPH and anti-oxidant activity by TBARS assay measuring lipid peroxidation using LDL. The $30\%$ and $60\%$ methanol fractionates of methanol extracts showed strong anti-oxidant activity compared to vitamin C. They also had more Potent SOD activity using pyrogallol at 250 ppm than that of vitamin C. These results suggest that anti-oxidant activities of motherwort may be applicable to development of natural anti-oxidant cosmetics. Possibility of nature anti-oxidation ability cosmetics is seen possibility low official.

  • Myocardial ischemia-reperfusion injury is known to be mediated by reactive oxygen species. The myocardial cell is equipped with endogenous antioxidant defensive system which can be adaptively stimulated by various oxidative stress. It is postulated that an increased oxygen partial pressure induced by hyperbaric oxygenation impose an oxidative stress on the cells, resulting alterations in the endogenous antioxidant system. In this study we investigated the effect of hyperbaric oxygenation on the activities of myocardial antioxidant enzymes and observed whether the hyperbaric oxygenation could protect the ischemia-reperfusion injury of heart. Rats or rabbits were pretreated with hyperbaric $oxygenation(2{\sim}3\;atm\;O_2/1{\sim}3\;hrs/1{\sim}10\;days)$. The changes in activities of major antioxidant enzymes(superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glucose-6-phasphate dehydrogenase), functional recovery and infarct size were observed in the experimentally induced ischemia-reperfused hearts. In the hearts isolated from rats pretreated with $2\;atm\;O_2/1{\sim}2\;hrs$ for 5 days, the functional recovery after reperfusion(20 min) following global ischemia(25 min) was significantly increased without any observable oxygen toxicity. Lactate dehydrogenase release was also significantly reduced in this hyperbaric oxygenated rat hearts. In in vivo regional ischemia(30 min) model of rabbit hearts, pretreatrment with $2\;atm\;O_2/1\;hr$ for 5 days significantly limited the infarct size. Among the myocardial antioxidant enzymes of rat hearts pretreated with the hyperbaric oxygenation, the activities of catalase, superoxide dismutase and glucose-6-phosphatase dehydrogenase were increased, while those of glutathione peroxidase and reductase were not changed. There were lethal cases in the groups of rats exposed to 3 atm $3\;atm\;O_2/2{\sim}3\;hrs$ for 5 days. A lipid-peroxidation product, rnnlondialdehyde was increased in brains and livers of the rats exposed to$2\;atm\;O_2/2{\sim}3\;hrs/5\;days\;and\;3\;atm\;O_2/1\;hr/5days$. The present results suggest that the pretreatment of hyperbaric oxygenation can protect the post-ischemic rererfused hearts in association with a stimulation of the activities of myocardial antioxidant defensive enzymes, and that the hyperbaric oxygenation of $2\;atm\;O_2/1\;hr$for 5 days would be a safe condition which does not produce any oxygen toxicity.
