Paecilomyces japonica and Cordyceps militaris were added to the materials for DongChungHaCho bread, and sensory and mechanical test were performed. Both control and 2% DongChungHaCho added group were acceptable in taste, mouthfeel and odor. Paecilomyces japonica added groups showed higher moisture and volume than control, and Cordyceps militaris stoups showed lower moisture and volume. DongChungHaCho added groups showed lower lightness than control.2% Paecilomyces japonim added group showed similar tendency to control, and it showed the best estimate especially in acceptance, moisture and volume. The optimal addition ratios of DongChungHaCho were evaluated by concentrations of 2% to 4% Paecilomyces japonim and of 2% Cordyceps militaris.

The effects of Saururus chinensis Baill administration on the biochemical parameters of function in liver of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) treated rats were investigated. Saururus chinensis Baill (200mg/kg) was administered into rats intraperitoneally for four weeks, seven days after the injection of TCDD(1 ${\mu}g/kg$). We examined the antioxidative enzymatic activity by measuring the level of AST and ALT in serum and SOD, Catalase, GPx, GSH and GSSG in liver tissue of rats. STT group showed 70.7% of inhibitive effect in AST acrivity compared to TTA group. ALT level of STT group was decreased to the level of NTT group. SOD and Catalase in TTA group were lower than in NTT group, but SOD and Catalase in STT group were increased by 82% and 55.45% respectively compared to TTA group. GSH contents in STT group were 74.20% increased compared to TTA group. GSSG contents in STT group were 61.08% decreased compared to TTA group. These results suggest that Saururus Chinensis Baill has a potent hepathprotective effect against TCDD intoxicated rats.

Purpose: This study investigated bone mineral density and nutritional state according to consumption of milk in Korean postmenopausal women who drink coffee. Methods: Using the 2008~2009 Korean National Health & Nutrition Examination Survey data, a total of 1,373 postmenopausal females aged 50 yrs and over were analyzed after excluding those with diseases related to bone health. According to coffee and/or milk consumption, subjects were divided into four groups: coffee only, both coffee & milk, milk only, and none of the above. All data were processed after application of weighted values and adjustment of age, body mass index, physical activity, drinking, and smoking using a general linear model. For analysis of nutrient intake and bone density, data were additionally adjusted by total energy and calcium intake. Results: The coffee & milk group had more subjects younger than 65 yrs and higher education, urban residents, and higher income than any other group. The coffee only group showed somewhat similar characteristics as the none of the above group, which showed the highest percentage of subjects older than 65 and in a lower education and socio-economic state. Body weight, height, body mass index, and lean mass were the highest in coffee & milk group and lowest in the none of the above group. On the other hand, the milk only group showed the lowest values for body mass index and waist circumference, whereas percent body fat did not show any difference among the groups. The coffee and milk group showed the highest bone mineral density in the total femur and lumbar spine as well as the highest nutritional state and most food group intakes, followed by the milk only group, coffee only group, and none of the above group. In the assessment of osteoporosis based on T-score of bone mineral density, although not significant, the coffee and milk group and milk only group, which showed a better nutritional state, included more subjects with a normal bone density, whereas the none of the above group included more subjects with osteoporosis than any other group. Conclusion: Bone mineral density in postmenopausal women might not be affected by coffee drinking if their diets are accompanied by balanced food and nutrient intake including milk.

This study was carried out to evaluate the effects of buckwheat powder on bread quality. Different breads were prepared with additions of 0%, 15%, 30%, and 45% buckwheat powder in place of wheat flour. The weights of the breads with buckwheat powder were in the range of 430.3 - 441.5 g, and the control was 421.3g. The volumes of the breads prepared with 15%, 30%, and 45% buckwheat powder were 2432.3 mL, 2219.3 mL, and 2090.8 mL, respectively. The water absorption rates of the breads with added buckwheat powder increased with the addition of buckwheat powder. Hardness increased with the addition of buckwheat powder, and was highest for the bread made with 45% buckwheat powder. The overall sensory quality of the buckwheat powder bread, which was tested by color and taste, was better than that of the control; specifically, the quality of the 30% buckwheat powder bread was the best.

Benign prostatic hyperplasia (BPH) is the most common urogenital disorder in men, benign tumor and is a typical disease deteriorating the quality of old men's lives, and its prevalence increases with age. Though the molecular pathogenesis of BPH has not yet been clearly revealed, it is known that the variation and aging of the endocrine including sex hormone may cause BPH. Especially the hypertrophy of the prostate cell by the formation of the excessive dihydrotestosterone (DHT) is estimated to cause BPH. If testosterone exists excessively in blood, a lot of DHT is produced in prostate by $5{\alpha}-reductase$. Thus, in this study we tried to analyze haematological change and histopathological change by using the model rat with BPH caused by hypodermic injection of testosterone to prove the effect of Houttuynia cordata extracts on BPH. Rats were divided into four experimental groups: no treatment group (N), the testosterone injection and D.W treatment group (DO), the testosterone injection and Houttuynia cordata treatment group (HO) and testosterone injection and finasteride treatment group (FO). Prostate weight, volume and weight ratio in the HO and FO groups were significantly lower than the DO group. Testosterone and DHT levels in the HO group were significantly lower than the DO group. The HO and FO groups showed trophic symptoms and were lined by flattened epithelial cells, thus, the stromal proliferation is relatively low as compared to the DO group. These results suggest that Houttuynia cordata may control benign prostatic hyperplasia.

In this study, we investigated the quality characteristics of cookies containing mesangi powder (MP). The cookies were stored at 30 $^{\circ}C$ for 28 days. The pH of the dough decreased significantly upon the addition of MP. The spread factor of the cookies also decreased significantly with more MP added to the cookie recipe. The loss rate of cookies was significantly higher in 3% and 5% cookies than in control and 7% cookies. The leavening rate was significantly decreased upon the addition of MP. Hardness was significantly higher in 5% and 7% cookies than in control cookies. The L, a, b values of cookies were significantly reduced at higher MP content. The results of sensory evaluation showed that cookies made with MP did not differ significantly from the control, except in color and moistness. The mineral contents of cookies increased in dose-dependent fashion with MP concentration. The acid and peroxide values were lower in cookies with 5% MP than other cookies.

Growth, feed efficiency and condition factor of the olive flounder fed supplemented diets containing different levels of Obosan were significantly (P<0.05), especialluy at the optimum level of 0.6% Obosan. The hematological values (RBC count, hemoglobin, hematocrit, MCHC, MCV and MCH) were not significantly different among the flounder fed diets containing different levels of Obosan (P> 0.05). However, serum concentrations of total protein and glucose in the flounder, feds Obosan supplemented diets, were significantly higher, while the levels of total cholesterol, COT and GPT were lower than those of control fish (P<0.05)i the values for COT and GPT were only about half that of the control (P<0.05).
