To investigate antioxidative and antiaging effects of yellow and black soybeans in vivo system, male SD rats (n＝24) were fed the diets containing casein (C), yellow soybean (YS) or black soybean (BS) for 8 weeks. Experimental groups showed the preventive effect on lipid and protein oxidation, especially protein oxidation of plasma was significantly inhibited in BS group. SOD and catalase activities were not different among the groups, but hepatic glutathione peroxidase (GSH-px) activity was significantly lowered in YS and BS groups compared with control group. The contents of superoxide anion radical in cytosol were significantly lowered in experimental groups compared with control group. And hydroxyl radical was slightly lowered in soybean groups. Lipofuscin accumulation on the heart and eyes of rats was effectively inhibited by yellow soybean and black soybean, respectively. In conclusion, these results suggest that yellow soybean and black soybean have the antioxidative/antiaging effect in vivo system and they have similar activities despite different color of seed coat.

This study was conducted to examine whether there is any effect of the local body exposure to hot and cold alternate stress on the blood flow and heart rate. Environmental condition was $20^{\circ}C$ air temperature, 65% relative humidity and 0.2m/s air movement. 22~32 years old four healthy female subjects wore clothes which they felt comfort sitting on a chair. And then their left hand was immersed twice in ($42^{\circ}C$\;and\;15^{\circ}C$ water alternately. Two of the subjects (E-group) were continually exposed to above condition 12 times. While, the other two (C-group) were exposed twice only at the 1st and 12th time of E-group's exposure. The results obtained from this experiment were as follows. \circled1 The initial response of the finger blood flow in I-group to the thermal stress showed more sensitively at the post-training than pre-training. \circled2 Heart .ate was higher in hand immersion at hot water ($42^{\circ}C$) than at cold water ($15^{\circ}C$) \circled3 The pattern of the blood flow of the finger and heart rate was different between E-group and C-group.

This study examined the effect of adhesive tape supplemented with sodium fluoride on the prevention of dental erosion in vitro. Sound bovine tooth samples were selected and divided randomly into the following 4 groups according to the material treatments: group 1, APF gel; group 2, fluoride varnish; and groups 3 and 4, fluoride tape supplemented with 5% NaF in either a methyl cellulose or poly vinyl acetate carrier, respectively. All specimens were submitted to alternate cycles of acid exposure in a cola beverage (pH 4.3) and artificial saliva for $6\;{\times}\;5\;min/day$ over a 5 day period. The micro-hardness was recorded each day and the lesion depth was measured after 5 days. The micro-hardness of the experimental sides of groups 2, 3 and 4 were significantly higher than that of their control sides and the experimental side of group 1 during the experimental period (p<0.05) except on the 5th day. The enamel surfaces of treatment groups 2, 3 and 4 showed significantly higher resistance to mineral loss in terms of the erosion depth (p<0.05) than group 1 and their control sides. There was no statistically significant difference among group 2, 3 and 4, indicating that the fluoride varnish and tapes produce similar results. Fluoride adhesive tapes are effective in reducing the progression of erosion and can be recommended for young patients who are more susceptible to dental erosion.

녹용이 동물체에 미치는 영향을 조사하기 위한 일환으로 녹용 침출액을 집토끼에 주사한 후 여기에서 여섯개의 조직(골격근, 간, 신장, 부신, 비장, 심장근)을 선택 적출하여 disc-gel electrophoresis로 수용성 단백 분획상을 비교 하여 보았다. 대조군과 5일간 주사한 군에서 간, 신장, 부신, 비장에서는 서로 동일한 영동분획상이 나타났으나 골격근과 심장근에서는 대조군보다 실험군(5일간과 15일간 녹용침출액을 주사한 군)의 영동대에서 하나의 영동대가 더 나타났다. 한편 15일간 주사한 실험군과 5일간 주사한 실험군 사이에서는 단백분 획상의 차이점이 없음을 알았다. 이와 같은 변화는 녹용의 어떤 특수성분이 주로 근육형 조직에서만 백질을 합성하는 기작에 영향을 끼친 것이 아닌가 사려된다.

This study was undertaken to investigate the effect of cognitive rehabilitation program (CRP) using virtual content, for recovering patients with cerebrovascular disease (CVD). A total of 34 patients with CVD were divided into a control group and an experimental group, and subsequently subjected to a virtual content based CRP, followed by cognition, ADLs, and upper limbs. The control group completed a universal rehabilitation program (URP), and the experimental group was provided a URP and a virtual content based cognitive rehabilitation program. For both groups, respective programs were conducted twice a day, 5 times a week for 4 weeks. Both groups showed significant improvement in ADLs (p<0.05); but the amount of change in the experimental group 5 point improved significantly (p<0.05). Cognition was significantly different for both groups (p<0.05). However, the experimental group showed a greater change (2 point) than the control group when considering the amount of change (p<0.05). Comparing the amount of change in the upper extremity, the experimental group showed a significant change (0.7 point) than the control group (p<0.05). This study confirms that compared to URP, CRP using virtual content significantly improves ADLs and cognition.
