This study was a quasi-experimental study of nonequivalent control group pretest- posttest design to investigate the effect of home rehabilitation exercise program on the physical and psychological functions of home stayed chronic hemiplegic stroke patients. The data were collected during the period of May 20th to August 15th, 200l. The subjects for this study were 40 hemiplegic stroke patients with the experimental group consisting of 19 patients and the control group being composed of 21 patients. The patients selected for this study were: (a)living in J city who had been diagnosed with stroke and at home after being discharged from the hospital, (b) suffering from stroke for 6 months to 5 years, (c) without recognition disorder with the MMSE-K(Mini-Mental State Examination-K)score above 25, (d) below 2 on the modified Ashworth scale, (e)free from heart and pulmonary disease, (f)able to walk beyond 15 minutes for themselves, (g) not taking regular exercises. The program for the experimental group provided 8 weeks' home rehabilitation exercise, two times of group education during the first week and individual education and supportive care after the second week through home visiting and telephoning more than once a week. The amount of time spent on rehabilitation exercise by the experimental group was 35 to 50 minutes a day, three times a week. In order to understand the effects of experiment the two groups were compared and verified by measuring the physical and psychological functions of both groups. The data were analysed by $\chi^{2}-test$, paired t-test and unpaired t-test and ANCOVA through SAS/PC program. The results of the study were as follows: 1. In terms of physical variables: grip strength. lower extremity muscle strength, walking time, ADL and serum lipid levels 1) There was no significant difference in the unaffected and affected grip strength between the two groups, even though the unaffected and affected grip strength was more improved in the experimental group than in the control group. 2) There was no significant difference in the unaffected lower extremity muscle strength between the two groups, even though the unaffected lower extremity muscle strength was more improved in the experimental group than in the control group. There was no significant difference either in the affected lower extremity muscle strength between the two groups, even though the affected lower extremity muscle strength was more improved in the experimental group than in the control group. 3) There was significant difference in walking time between the two groups. Walking time was significantly reduced in the experimental group whereas it increased in the control group. 4) There was significant difference in ADL score between the two groups. ADL score was significantly increased in the experimental group, but it significantly decreased in the control group. 5) There was significant difference in serum total cholesterol level between the two groups. After experiment the serum T-C level became lower in the experimental group whereas it became sigficantly higher in the control group. 2. In terms of psychological variables: depression and self-esteem 1) There was no significant difference in the depression between the two groups, even though the depression showed constant in the experimental group, but it showed a significant increase in the control group. 2) There was no significant difference in the self-esteem between the two groups, even though the self-esteem showed some increase in the experimental group, but it significant decrease in the control group. As shown above, the results of 8 weeks' home rehabilitation exercise program for chronic hemiplegic stroke patients produced positive effects on walking time, ADL score and serum T-C level, shortening walking time, improving activities of daily living(ADL) and lowering serum total cholesterol level.

Physiological functions of raw grain diet composed of brown rice and Job's Tear (1 : 1) were evaluated in rats raised with nutritionally unbalanced diet including 1% cholesterol, high proportion of animal lipids (lard: soybean oil : 8 : 2), sub-optimal levels of vitamin and mineral mixture along with 0.5% ethanol in drinking water for 4 weeks. Control rats were fed the AIN-93G diet for 9 weeks, and nutritionally unbalanced rats were divided into 3 groups, and fed one of the following diets with 0.5% ethanol in drinking water for another 5 weeks: unbalanced control diet (UCD), raw grain diet (RGD) (UCD +20% brown rice and Job's Tear mixture, and cooked grain diet (CGD)(autoclaved RGD at 121$^{\circ}C$ for 3 hours). Feeding UCD for 5 weeks significantly lowered the food efficiency ratio (FER) of rats than the value for control animals, and dietary supplementation of brown rice and Job's Tear mixture to UCD significantly restored the FER. Serum total cholesterol concentration was significantly lowered in rats fed RGD (24% decrease) or CGD (16% decrease) compared to the value for rats fed UCD. Feeding RGD for 5 weeks significaly lowered the serum LDL+VLDL-cholesterol concentration (26% decrease), as well as the hepatic cholesterol level (16% decrease) than the values for UCD rats. Animals fed CGD (38% decrease) or RGU (59% decrease) showed significantly lower level of hepatic thiobarbituric acid reactive substances (TBARS) compared to the value for rats fed UCD (p<0.05), although hepatic activities of antioxidative enzymes were not influenced by dietary supplementation. Feeding RGD for 5 weeks significantly increased CD4$^{＋}$ T-cell population along with CD4$^{＋}$/CD8$^{＋}$ ratio of mesenteric lymph nodes compared to those for UCD rats (p<0.05). In conclusion, dietary supplementation of brown rice and Job's Tear mixture as raw grains exhibited superior activity lowering blood and hepatic levels of cholesterol, and improving mesenteric lymph nodes immune function of rats to the cooked grain mixture of identical ingredients.

The effect of fermented soybean culture of Bacillus subtilis MORI mixed with mulberry leaves on the lowering the levels of blood glucose and cholesterol was examined using neonatal streptozotocin-induced diabetic (n-STZ) rats. B. subtilis MORI produces 1-deoxynojirimycin (DNJ), an $\alpha$-glucosidase inhibitor. The content of DNJ of soybean fermented culture mixed with mulberry was higher (4.1$\pm$0.0 mg/g dry base) than that (1.5$\pm$0.0 mg/g) of mulberry. The concentration of 50% inhibition (IC50) against rat intestinal $\alpha$-glucosidase of soybean fermented culture mixed with mulberry was $5.6{\pm}0.1{\mu}g$/mL and that of mulberry was $17.0{\pm}0.5{\mu}g$/mL. Experimental groups of diabetic rats were randomly assigned to normal control group (NC group), diabetic control group (DC group) and three diabetic groups fed with DNJ food product. One of the three diabetic groups was M group (60 mg DNJ food product/kg) (DNJ food product containing 30% mulberry) and the other two were MM-60 group (60 mg/kg) and MM-120 group (120 mg/kg) (DNJ-fortified food product containing 30% fermented soybean culture mixed with mulberry leaves). The glucose in serum was significantly decreased in the MM-60 and MM-120 groups fed with DNJ-fortified food product for 4 weeks, compared with DC group. Total cholesterol and triglyceride in serum were also lower in MM-60 and MM-120 groups than the DC group. These results support that the fermented soybean culture of B. subtilis MORI mixed with mulberry leaves improved the metabolism of blood glucose and lipid in the n-STZ rat model.

This study was designed to evaluate the anti-diabetic effects of Buan mulberries by using an insulin-dependent diabetes mellitus animal model. Several studies have shown that mulberries have metabolism-improving, antioxidant, and lipid-lowering properties in rats with streptozotocin (STZ)-induced diabetes. In this study, Sprague-Dawley male rats were randomly assigned to 1 normal control group and 5 STZ-induced diabetes groups: rats that had STZ-induced diabetes and did not receive any agents (diabetic group; negative control), rats that had STZ-induced diabetes and received insulin (insulin group; positive control), rats that had STZ-induced diabetes and received 0.5% mulberry extract (0.5% mulberry group), rats that had STZ-induced diabetes and received 1.0% mulberry extract (1.0% mulberry group), and rats that had STZ-induced diabetes and received 2.0% mulberry extract (2.0% mulberry group). Mulberry extracts were administered to the diabetic animals for 4 weeks. The rats that received mulberry extracts showed lower body weights and insulin levels, as well as higher kidney weights, blood glucose levels, urine quantities, and water intake in comparison with the normal controls. Further, the insulin concentrations in the mulberry-fed animals were higher than those in the diabetic group, and the kidney weights, blood glucose levels, urine quantities, and water intake in the mulberry-fed animals were lower than the corresponding values in the diabetic controls. These results suggest that mulberry may be an effective functional food to prevent diabetes-related complications.

This study was conducted to know the storage stability of Yackwa, a traditional Korean fried cookie, prepared by two different cooking methods; deep fat frying at 160$^{\circ}C$ for 8 min (DFF), and preheating Yackwa dough and then deep fat frying at 180$^{\circ}C$ for 2 min (MW/DFF). Soybean oil (SBO), hydrogenated soybean oil (HSBO) or hydrogenated palm oil (HPO) were used for frying Yackwa. Compared to Yackwa prepared by DFF, all MW/DFF Yackwa samples had low fat content and high moisture content. MW/DFF saved frying time 6 min compared with DFF. Non-hydrogenated soybean oil for frying fats was replaced with hydrogenated types of soybean oil and palm oil to improve the storage stability of Yackwa. To investigate the oxidation stability of Yackwa during the accelerated storage for 15 days at 60$^{\circ}C$, acid value, anisidine value, peroxide value and oxidation value of Yackwas were measured. Acid values of Yackwa made by MW/DFF were higher than those made by DFF through the whole storage periods, regardless of frying fats. Peroxide and anisidine values of Yackwa coated with syrup were much lower than those without syrup. MW/DFF cooking method, using hydrogenated soybean oil or hydrogenated palm oil for frying, showed lowering effects on peroxide value as well as anisidine value, resulting in improved oxidation stability of Yackwa during the storage. In sensory evaluation, the acceptability of MW/DFF Yackwa was higher than those of the commerical products. Yackwa prepared by MW/DFF cooking method using hydrogenated palm oil, showed the highest acceptability in color, taste and texture among the samples.

The effects of administration alone or mixed of Angelica keiskei and turmeric extract on blood lipids were evaluated in hypercholesterolemic diet or P-407-induced hyperlipidemic rats. In the study 1, female Sprague-Dawley rats weighing 160-180 g were divided into each groups and fed high cholesterol diets for 8 weeks. Experimental groups were administered with following diets: basal diet (Normal), high cholesterol diets (1% cholesterol). We did the oral administration for evaluation in experimental groups: C (vehicle), A (angelica extract), T (turmeric extract), AT (angelica extract, turmeric extract/ 1:1 complex). The concentrations of serum total cholesterol, and LDL-cholesterol were decreased by 6.8%, 9.8% in A group, by 22.1%, 28.8% in C group and by 28.2%, 35.6% in AT group, compared to the C group, respectively. HDL-cholesterol levels were not different among the experimental groups. In the study 2, we induced the hypertriglyceridemia in rats by intraperitoneal injection of P-407 (0.5 g/kg) once per three days. From the next day after P-407 injection beginning, we did the oral administration as the study 1. Angelica keiskei extract, turmeric extract and complex extract decreased serum triglyceride by 17.2%, 19.7% and 48.3%, respectively. These results suggested that Angelica keiskei and turmeric extract complex might have synergistic effect in lowering total cholesterol, LDL-cholesterol and triglyceride in hyperlipidemic rats.

It is now well established that the rodenticide Vacor (N-3-pyridyl-mehtyl-N'-p-nitropheny-lurea) causes a hyperglycemia in human and rats. It is also reported that there are some components (DPG-3) in ginseng radix which cause hypoglycemic effect on alloxan diabetic mice. In the present study, attempts were made to demonstrate in Vacor-poisoned rats the hypo-glycemic activity of red ginseng component(RGC), which was extracted by Kimura's DPG-3 extraction procedure and found to be effective for lowering a hyperglycemia in alloxan-diabetic rats. Vacor in a dose of $LD_{50}$ (10mg/kg) produced a glucose intolerance with a paradoxical moderate increase in blood immunoreactive insulin and derangement in glucose metabolism of epididymal adipocytes in rats. Although RGC (20mg/kg, i.p.) did not exert any significant influence on a hyperglycemia induced by large lethal doses (25mg/kg) of Vacor ingestion, it improved the LDso Vacor-induced glucose intolerance and caused a further increase in blood insulin levels in Vacor-poisoned rats. The administration of RGC (20mg/kg, i.p.) normalized Vacor-induced depression of glucose metabolism and lipogenesis in the epididymal adipocytes with an improvement of reduced responses to insulin of adipocytes from Vacor-poisoned rats. These results suggest that some red ginsneng components contained in RGC fraction normalize the depressed peripheral glucose unitlization and insulin response and eventually lead to an improvement of abnormal glucose tolerance developed in rats poisoned with small doses of Vacor.

There is a rising trend in obesity due to various factors, including changes in eating habits, lack of exercise, and genetic and psychological factors. Citrus peel has been reported to prevent obesity via antioxidative, antihypertensive, and LDL cholesterol-lowering effects. This study investigated the effects of citrus peel extract fermented with or without Aspergillus oryzae in a mouse model of diet-induced obesity. The animals were divided into four groups: a high-fat diet group (HFD), a normal fat diet (NFD) group, a citrus peel extract (CP) group, and a citrus peel extract fermented with A. oryzae (CPA) group. The citrus peel extract improved lipid metabolism and weight loss in the high-fat diet-induced obese mouse model. As expected, the body weight was higher in the HFD group compared with the NFD, CP, and CPA groups. However, the concentrations of total cholesterol (TG) and triglyceride (TC) in the serum and liver of the CP and CPA groups were lower than in the HFD group. There were no significant differences in the HDL cholesterol concentration among the groups. Taken together, our results suggest that extract of citrus peel biotransformed with A. oryzae had more antiobesity activity than citrus peel not transformed by A. oryzae through the fermentation of metabolites.

The efficacy of extraction from Inonotus obliquus was examined from the points of antioxidative characteristics and some antioxidative compounds. To enhance the efficient extraction for the effective components from Inonotus obliquus, temperature-stepwise water extraction method was applied. Temperature-stepwise water extracts were prepared for 8 hrs as follows: the first extract at 8$0^{\circ}C$, the second extract from the residue of the first extract at 10$0^{\circ}C$, and the third extract from the residue of the second extract at 12$0^{\circ}C$. Antioxidativeactivities were determined by electron-donating ability of DPPR - free radical, scavenging ability of ABTS$.$$^{+}$radical cation, and by inhibiting ability of linoleic acid autoxidation. In results, the first extract showed the least antioxidant capacity, and the third extract showed the highest antioxidant capacity. The third extract also had the greatest amounts of phenolic compounds and flavonoids. Amounts of phenolic compound from each extract were almost proportional to the radical scavenging activities and linoleic acid autoxidation inhibiting ability (r=0.960∼0.980, regression analysis). Furthermore, the effect of the pooled extract of all three extractions of Inonotus obliquus on the lipid peroxidation reacted with active oxygen species (KO$_2$, $H_2O$$_2$, $.$OH) and metals (Fe$^{2+}$, CU$^{2+}$) was evaluated by measuring the formation of thiobarbituric acid reactive substances (TBARS). The pooled Inonotus obliquus extracts lowered the amounts of TBARS formed by all of the active oxygen species and metals. Especially, these lowering effects were pronounced in the reaction with $.$OH and Fe$^{2+}$. These results suggest that the pooled temperature-stepwise extract from Inonotus obliquus could be potential functional materials to reduce the oxidation of lipids and other compounds induced by free radicals.adicals.
