The purpose of this study was to investigate the anti-apoptosis-related protein expression in skeletal muscle of rats with different amount of mountain ginseng (MG) added high-fat diet fed. Twenty-four Sprague Dawley male rats were divided into the high-fat diet control group (CON), 0.5% of MG added diet group (MG1), and 1.0% of MG added diet group (MG2) with eight rats each. The P53, anti-apoptotic protein, was significantly lower in MG2 than CON and MG1. The bcl-2 and bcl-xl, however, were not significantly different from MG1 but from CON. The caspase-9 and -3, were significantly lower in MG groups than CON. In addition, it was dramatically lower in MG2. These results suggested that MG addition to the high-fat diet suppressed p53 protein expression and enhanced anti-apoptototic protein expression. MG may be a positive effects on health as a medicinal plant.

A survey was conducted in 591 college students using 8 different cafeterias serving 31 meals. The information was obtained about the name and amount of dishes they consumed from the menu offered by college foodservice. Mean nutrient contents per meal in offered menu were higher than 1/3 of RDA for their age, sex in offered menu. The mean energy content was 466kcal from rice, 113kcal from soup, 141kcal from side dish and 21kcal from kimchi. When side dishes were classified by cooking methods, side dishes using grilling, frying, roasting methods had high energy content and fat percent above 200kcal, 40% per dish. By main ingredients, side dishes with animal food were higher energy than with plant food. Students consumed 94% of the energy provided in offered menu. When compared to proportion of foods consumed by sex, there was 43% of female and 22% of male consumed less than half in soup and 31% of female and 12% of male in kimchi. The most prevalent menu patterns of subjects included rice, soup, 2 side dishes, kimchi and were the same in both sexes. Mean energy intakes per meal were 989kcal for males and 842kcal for females which were enough to meet 1/3 of RDA for their age and sex. Most nutrient intake except fat and vitamin B1 were higher in set menu than in cafeteria. Nutrient adequacy ratio(NAR) were above 0.9 except calcium and vitamin A. The mean energy intake was 542kcal from rice, 70kcal from soup, 164kcal from side dish and 20kcal from kimchi. In conclusion, intake of most of the nutrients of students obtained from males in college foodservice were sufficient but calcium intake was insufficient and fat content was above 20% of energy. High fat consumption was due to side dishes from frying, grilling, roasting with animal food. To provide desirable meals in college foodservice, use of fat in cooking must be decreased.

This study evaluated the general nutritional ingredients such as crude fats, crude ashes, crude proteins, total polyphenols, and total flavonoids in 18 kinds of edible tree sprouts. The tree sprouts of Philadelphus schrenckii, Lycium chinense, and Morus alba had the highest crude fat, crude ash, and crude protein content, respectively. The tree sprouts of Cedrela sinensis (CSS) with high ABTS⁺ radical scavenging activities had a high content of total polyphenols (175.65 mg/g ext.) and total flavonoids (75.18 mg/g ext.). The simultaneous determination of flavonoids such as rutin, isoquercitrin, quercitrin, afzelin, and quercetin in CSS was conducted using high-performance liquid chromatography with a wavelength of 270 nm. Among the flavonoids, the content of quercitrin in CSS was the highest at 59.28 mg/g ext. This study also aids the quality control of many edible tree sprouts by analyzing the general components, total polyphenols, and total flavonoids.

Anti-obesity effects of ginseng and herbal plant mixtures were investigated to develop natural materials for anti-obesity. After inducing obesity with high fat diet for 8 weeks in male SD rats, ginseng and herbal plant mixtures DM1 (ginseng, puer tea, opuntia) and DM2 (ginseng, puer tea) were administrated orally to rats for another 8 weeks. During administration, food efficacy ratio and body weight of rat were measured twice weekly. After administration, body weight, body fat contents, and serum lipid level were estimated for anti-obesity effect and hematological analysis blood level of ALP and ASP was checked for safety. Body weight in rats fed high fat diet was significantly increased. Body weight in obese rats induced by high fat diet was significantly decreased by DM1 and DM2 feedings. The amount of body fat (epididymal, perirenal and visceral fat, brown adipose tissue) was significantly reduced by DM1 and DM2 treatments. The amount of TG, the concentration of leptin in blood plasma, and the concentration of insulin in blood plasma were significantly diminished by DM1 and DM2. Lipid accumulation on liver was reduced in DM2. There were no side effects among all groups according to blood analysis, hematological findings, and body weight. The findings of this study suggest that DM1 and DM2 may be effective materials for anti-obesity through reducing plasma triglyceride and body fats, and also decreasing body weight without side effects.

Consumption of vegetables and fruits is associated with a reduced risk of stroke, but it is unclear whether their protective effects are due to antioxidant vitamins or folate and metabolically related B vitamins. The purpose of the study was to test the hypothesis that intake of fruits and vegetables, which are major sources of antioxidant and vitamin B complex vitamins, reduces the risk of stroke. Cases consisted of patients diagnosed with first event of stroke (n = 69). Controls (n = 69) were age-, sex-, and body mass index-matched to cases. Multivariable-adjusted regression analysis showed that subjects who ate four to six servings of vegetable per day had a 32% reduction in the risk of stroke, and those with more than six servings per day had a reduction of 69% after adjusting for age, sex, BMI, and family history of stroke. Intakes of total fat, plant fat, calcium, potassium, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, niacin, and folate were significantly and negatively associated with the risk of stroke. Although the trend was not significant, stroke risk was reduced in the second quartile (1.21-2.66 servings per week) of fish intake. However, intake of fruits (average daily intake of 1.0 serving) and antioxidant vitamins such as carotene, vitamin C, and vitamin E was not associated with the risk of stroke. In conclusion, our observational study suggests that intake of fat and vegetables, rich sources of vitamin B complex, calcium, and potassium may protect against stroke.

This experiment was conducted to clarify the plant growth promoting effect of compost supplemented with cultured solution of photosynthetic bacteria(Rhodopseudomonas capsulatus) before sowing on the early growth of plug seedling of tomato and to evaluate the optimum concentration of bacterialization. Bacterializing concentrations(v/w) to the compost were 2%, 3.3%, 10%, 20% and 50%, respectively. Plant growth in terms of plant height, stem diameter, leaf area, total fresh and dry weight were promoted by the bacterialization of photosynthetic bacteria. Especially, in the plots supplemented with 10 to 20% the early growth was promoted markedly over 2 times. Compositions of photosynthetic bacteria consisted of crude protein 60.7%, soluble carbohydrates 20.1%, crude fat 7.6%, crude fiber 3.2% and crude ash 4.8, respectively.

The herb of Allium victorialis var. platyphyllum (Liliaceae) has been used as an edible wild herb and to treat heart failure and gastritis. We have already reported antihyperlipidemic anti-tumor effects of this plant. To enlarge the commercial availability of this food, it was investigated whether the extracts of A. victorialis var.platyphyllum reduce hyperlipidemia and obesity or not. The plants tested in this experiment were collected from two eco-types of IS. Ullung and Mt. Odae cultivated at Pyongchang. Extracts were prepared by extracting the fresh leaves and those dried at $36^{\circ}C$ and $90^{\circ}C$, respectively. Pretreatment with the ethanolic extracts for two weeks (p.o.) reduced serum triglyceride-, total cholesterol- and LDL-cholesterol contents in rats induced by Triton WR-1339, respectively. Furthermore, oral administration of the extracts also inhibited the hyperlipidemia induced with oral diet of 30% corn oil. In the other attempt to find to alleviate the obesity, the model rats with obesity were induced by the high fat-diet for six weeks. Post-treatment with the extracts for two weeks significantly reduced the hyperlipidemia. Retroperitoneal-, epidymal- and total abdominal fat pad weights were considerably reduced at 100 mg/kg oral administration of the extracts. Increased feces lipid contents were also found in the rat treated with the extracts. The extract of Mt. Odae eco-type showed more potent activity than that of Is. Ullung one. These results suggest that use of the fresh leaves may lead to the higher activity in treatment of hyperlipidemia and obesity than of the dried one.

Previous studies have shown that plant-based vegetarian diets, which typically contain a variety of antioxidants and dietary fiber, help reduce the risk of heart disease, diabetes, obesity, and cancer. However, some studies have reported that vegetarian diets can lead to deficiencies in protein and trace minerals compared to non-vegetarian diets. This study was conducted to compare anthropometric measurements, blood parameters, dietary intake, and hair mineral status in long-term vegetarians (MV; moderate vegan, LV; lacto-ovo vegetarian) and non-vegetarians (NV). Thirty MV (12 males, 18 females; mean age, $50.58{\pm}5.05$ years), 15 LV (11 males, four females; mean age, $49.45{\pm}4.97$ years), and 30 NV (15 males, 15 females; mean age, $48.90{\pm}3.62$ years) participated. No significant differences were observed for age, height, weight, or body mass index, but body fat was significant lower in MV and LV males than that in NV males. White blood cell counts of MV, LV, and NV male subjects were significantly different. Dietary intake data showed that plant protein and plant iron intake were significantly higher in MV and LV than those in NV. Animal protein, animal fat, and animal iron intake were significantly higher in NV than those in MV and LV. A hair mineral analysis showed that calcium and iron were higher in the hair of MV and LV than those in NV. Zinc concentration in hair was not significantly different among the groups. The results suggest that vegetarian diets are adequate to sustain mineral status to at least the same degree as that of non-vegetarian diets.

The objective of this study was to develop the classification method of various organic wastes. Specifically, the effects of proximate composition on the biogas production and degradation rates of agricultural by-production was investigated and a new standards for mixture of various organic wastes based on proximate composition combination was developed. Agricultural by-products (ABPs) with medium total carbohydrate, medium crude protein and low fat contents demonstrated the single step digestion process. ABPs with low total carbohydrate, high crude protein and high fat contents demonstrated the two step digestion process of Diauxic growth. The single ABP (Class No. 15) and the mixed ABPs (Class No. 12+18, 6+12+22, 9+12+18) after 10days showed the similar biogas yield pattern. We can use the classification method for the more ABPs and organic wastes from factory and municipal waste treatment plant for the high efficient biogas production.
