The purpose of this study aims guarana ingestion to possibly be Ergogenic Aids(EA) for elite male athletes who do long time exercises. Participators who play long distance belong to H-university. They are measured HRmax by polar and treadmill, and they do run on the treadmill for 60 minutes with HRmax 70%. Participators ingest 200ml guarana and water for 5 times. They were drawn blood for 3 time such as before 30 minutes, after finish, and after 30 minutes later. Data processing was repeated of the measuring, two way repeated ANOVA, according to guarana ingestion, water ingestion, and treatment time. The result of this study identifies that guarana ingestion is more positive effect with glucose, Free fatty acid, and lactic acid than water. Hence, guarana ingestion is including function of EA to increase reserving energy on the body for rising kinetic ability.

Colon cancer is the most common form of cancer diagnosis in worldwide. There are growing interests in the health benefits associated with consumption of fruits and vegetables, especially for the prevention of cancer, cardiovascular or other chronic diseases. The objective of the present study was to investigate the antioxidant and anticancer activities of natural product, guarana(GR) and graviola(GV) in human colon carcinoma HCT-116 cells. MTT assay, flow cytometry analysis were employed to investigate the anticancer mechanism and DPPH assay was determined to the antioxidant activity to scavenge free radicals in extract of these. All two extracts showed significantly antioxidant activity at 50mg/ml of concentration. GR and GV reduced HCT-116 cell proliferation in a dose dependent manner. Specially GR treatment(96.65±3.71) also significantly increased the sub-G1 population more than GV(79.58±2.87) treatment in HCT-116 at the concentration of 10mg/ml, as shown by flow cytometry assay. Statistical analyses revealed GR and GV exhibited significantly high (P < 0.05) cytotoxicity in HCT-116. These findings indicate that GN and GV may serve as novel therapeutic agents for colon cancer treatment and future leads for drug development.

1997년이 저물기 전, 치협은 구강보건전담부서 부활이라는 치과계의 숙원사업을 성취했다. 구강보건전담부서가 설치됨가 동시에 앞으로 어떻게 운영되어야 하는지에 더욱 촉각을 곤두세우며 실무자들은 대응책에 고심하고 있는데.... 작은 정부 지향이라는 기본적 정부 정책 앞에서 게획적으로 내실있는 운영으로 구강보건과를 더욱 발전시켜야 한다는 여론이 높은 가운데, 구강보건과라는 '보석함'에 어떤 '보석'을 채워야 국민 모두와 치과계에 도움이 될까? 구강보건전담부서 부활로 국민의 구강보건 증진과 치과계의 발전을 기대하며 보건복지부와 대한치과의사협회, 치과계 인사의 견해를 들어보고 앞으로의 구강보건과를 전망한다.

Caffeine, a psychoactive stimulant, has been implicated in the modulation of learning and memory functions due to its action as a non-selective adenosine receptors antagonist. On the contrary, some side effects of caffeine have been reported, such as an increased energy loss and metabolic rate, decrease DNA synthesis in the spleen, and increased oxidative damage to exerted on LDL particles. Therefore, the aim of this study was to develop a safe stimulant from natural plants mixture (Aralia elata, Acori graminei Rhizoma, Chrysanthemum, Dandleion, Guarana, Shepherd's purse) that can be used as a substitute for caffeine. Thirty SD rats were divided into three groups; control group, caffeine group (15.0 mg/kg, i.p.), and natural plants mixture group (NP, 1 mL/kg, p.o.). The effect of NP extract on stimulant activity was evaluated with open-field test (OFT) and plus maze test for measurement of behavioral profiles. Plasma lipid profiles, lipid peroxidation in LDL (conjugated dienes), total antioxidant capacity (TRAP) and DNA damage in white blood, liver, and brain cells were measured. In the OFT, immobility time was increased significantly by acute (once) and chronic (3 weeks) supplementation of NP and showed a similar effect to caffeine treatment. Three weeks of caffeine treatment caused plasma lipid peroxidation and DNA damage in liver cells, whereas there were no changes in the NP group. NP group showed a higher plasma HDL cholesterol concentration compared to the caffeine group. The results indicate that the natural plants mixture had a stimulant effect without inducing oxidative stress.

This study analysed Emergency Medical Technology(EMT) students' satisfaction in clinical practice. It was discovered that satisfaction was a means of 3.61(${\pm}0.70$) and the factor which had a significant influence on satisfaction was desired job area (F=3.98, p=0.004). The factors which were significant to satisfaction were practice beginning grade(t=0.43, p=0.038), period of practice(F=2.82, p=0.025), and departments(F=11.81, p=0.000) In respect to significant positive correlations between practice procedures and satisfaction, observation frequency (r=0.221, p=0.000) and practice frequency(r=0.170, p=0.002) had significantly positive correlations with satisfaction. Based on the results above, it is suggested that to enhance EMT students' satisfaction in clinical practice, students should have clear points of view on their job and practice beginning grade and practice period should be properly considered according to characteristics of students. Also, effective practice programs which carefully consider peculiarity of Emergency Medical Technology should be developed further.

Prostate cancer(PrCa) is a leading cause of cancer-related death in man. Medicinal plants are exploited for many drugs to treat various ailments. The drugs derived from the plants promote health, augmented the resistance of the body against disease. Pueraia lobata(wild) Ohwi(P. Lobata), kudzu, which is a twining perennial woody herb native to China, Korea, Japan, India, and the United States. Plants such as Moringa oleifera, have hypoglycemic properties and other beneficial properties. The objective of the study was to analyze the effects of kadzu and moringa, natural plant products on antioxidant activity and proliferation of the hormone-sensitive prostate cancer LNCaP cells. MTT assay, flow cytometry analysis were employed to investigate the anticancer mechanism and DPPH assay was determined to the antioxidant activity to scavenge free radicals in extract of these. All two extracts showed significantly antioxidant activity at 10 and 50mg/ml of concentration. kadzu and moringa reduced LNCaP cell viability in a dose dependent manner. Specially moringa extract was more potent cytotoxic than kadzu extract. Statistical analyses revealed kadzu and moringa exhibited significantly higher (P < 0.05) cytotoxicity and antioxidant activity in LNCaP. The finding of this study provides a scientific basis for using kadzu and moringa in future development of chemotherapeutic drugs against hormone-sensitive prostate cancer.
