Traditionally, Cham dang-gui (Angelica gigas Nakai) is one of the most popular herbal medicines in Asian countries including Korea. A. gigas has been used as a functional food product for treatment anemia, women's health care, a sedative, an anodyne or a tonic agent. Decursin and decursinol angelate isolated from the roots of A. gigas are pyranocoumarin compounds. Recently, as the global herbal medication market is increasing, investigations about pharmacological effects of decursin and decursinol angelate are rapidly increasing. We summarized previous studies about pharmacological effects of decursin and decursinol angelate, and reviewed relation with pharmacological effects of decursin and decursinol angelate on human disorder, focused on the approach for new drug development. Pharmacological effects of decursin and decursinol angelate were classified as anti-tumor activity, anti-bacterial activity, improvements of the circulating system, inhibition of cytochrome P-450 activity, anti-inflammation activity, anti-oxidant activity and cognitive-enhancing activites. The activity of A. gigas with improvement of the circulating system may have wide therapeutic potential for circulatory diseases, including diabetes, hyperlipidemia and atherosclerosis. Also, anti-inflammation activity A. gigas may be beneficial for the treatment and prevention of asthma, atopic dermatitis and rheumatism arthritis. This relation could potentially lead to the development of herbal new drugs. In order to development a new drug containing decursin and decursinol angelate, it is also necessary to consider the safety profile, and the information in this review would contribute to development a new drug from herbal medicine.

Objectives: Elderly individuals with diabetes should maintain a normal body mass index (BMI) to help control their blood glucose levels. This study investigated barriers to physical activity (PA), self-efficacy to overcome those barriers, and PA self-efficacy among elderly individuals with diabetes in relation to BMI. Methods: This cross-sectional study included 56 participants. Data were collected by a questionnaire interview and direct measurements for anthropometric data. PA self-efficacy was measured using 8 questions describing different levels of PA, where participants rated the strength of their belief that they could engage in that activity. Self-efficacy to overcome barriers was measured using 10 questions capturing participants' confidence in their ability to engage in PA despite different possible barriers. Mean scores for these parameters were analyzed using the chi-square test and the independent t-test. Results: In total, 89.3% of participants had a low PA level and 58.9% had more than 3 hours of sedentary activity per day. Furthermore, 55.4% were obese and 14.3% were overweight. The mean scores for PA self-efficacy and self-efficacy to overcome barriers were $59.1{\pm}26.4$ and $52.5{\pm}13.8$, respectively. PA level was related to BMI (p<0.001; r=0.116) and sedentary activity (p<0.05; r=0.274). PA self-efficacy and age were not related to BMI. Barriers to PA were associated with PA levels (p<0.05). Conclusions: Physical inactivity was a major problem in elderly individuals with diabetes, and was correlated with higher BMI. Lower levels of PA might be mediated by sedentary activity.

This dissertation is try to figure out why chestnut belongs to kidney channel, from the viewpoint of five elements theory. After studying chestnut's property, flavor, channel tropism, main cure ability, prescriptions, shape, sweet, and prohibitions, I came to the following results. 1. Property of chestnut is warm and has no toxicity, so it is less related than kidney property. 2. Flavor of chestnut is salty and sweet, so it has some relation to kidney and spleen properties. 3. Channel tropism of chestnut enters mainly into kidney channel, and then spleen and stomach channels. 4. Chestnut controls kidney function of storing the essence of life, determining the condition of bone and marrow, conduction water metabolism, affecting reasoning activity, and controls activity of nine openings of body. It also has effects on functions of spleen, intestines and stomach. 5. Prescriptions including chestnut is similar to that of human brain, it is possible to reason out that chestnut has some relation to human brain. 7. As flavor of chestnut flower is similar to that of spermatic fluid, so it has som relation to kidney property. 8. As chestnut has property of blocking qi and it causes spleen, stomach and colon system to be confused, so it is suggested that persons with weakende spleen and stomach be not allowed to take in.

PURPOSE: This study assessed the influence of bilateral coordination exercises on unstable support surfaces on leg muscle activation and balance in stroke patients. METHODS: Two groups were recruited for comparison: an experimental group of 10 individuals who performed bilateral coordination exercises on unstable surfaces and a control group of 10 individuals who performed the same exercises on stable surfaces. All participants were assigned randomly. Pre-tests were conducted to measure the leg muscle activation and balance levels of the participants prior to the experiment. The intervention was comprised of three 30-minute weekly sessions for four weeks, followed by a post-test after the four-week period. RESULTS: Significant differences were identified within the experimental group in relation to all muscles (p < .01) and balance (p < .05). Within the control group, significant differences were identified in relation to the rectus femoris muscle, biceps femoris muscle, and balance (p < .05). Significant differences between the two groups were only observed in relation to the tibialis anterior and soleus muscles (p < .05). CONCLUSION: Only the tibialis anterior and soleus muscles showed significant differences between the two groups. This effectiveness may be attributed to using an ankle strategy to maintain body balance during exercise on unstable surfaces.

In order to know the antifungal characteristics of saturated fatty acids having 6 to 12 carbons, their minimum inhibitory concentrations (MICs) and minimum fungicidal concentrations (MFCs) were estimated against Saccharomyces cerevisiae. Fatty acids from C6 to C11 exhibited increasing activity with chain length, but C12 fatty acid did not show activity at all. In relation to antifungal modes of actions, fatty acids investigated showed on inhibitory activity toward the plasma membrane H+-ATPase of Saccharomyces cerevisiae. Their inhibitions to the glucose-induced acidification and ATP hydrolysis caused by the proton pump were found to be in common wiht antifungal activities. At the test concentration of 1mM, hexanoic acid (C6) showed the lowest inhibition of about 30%, while undecanoic acid(C11) showed the strongest inhibition of over 90%. In addition, as seen with antifungal activity, the inhibitory activity of dodecanoic acid (C12) was suddenly reduced to less than 50%.

Two field tests were conducted in 1995 to examine the effects of composts and soil amendments on physicochemical properties of soil in relation to Phytophthora root and crown rot of bell pepper. Chitosan, crab shell waste, humate, sewage sludge-yard trimmings, and wood chips were applied to test plots, some of which affected the levels of P, K, Mg, pH, and H. Physicochemical properties were not related with disease incidence, but percent organic matter, estimated nitrogen release, K, and Mg were correlated with total microbial activity. The elements K and Mg were especially responsible for the increased soil microbial activity that could affect development of root and crown rot of pepper.
