The reason that aromatherapy began to draw attention again as the alternative therapy is because the essential oils that are used for aromatherapy not only allow the human body to maintain homeostasis but also have an effect on curing a mental feeling of fatigue and because these efficacies and effects are proceeding with being proved scientifically. Also, with coming to be high in a voice of concern about severally side effects that the modern medicine and the synthetic chemistry have, the aromatherapy came to be paid attention as the replacement therapy that can substitute for and supplement this. In particular, at the time of requiring a study on a substance to substitute for this after having been announced in Japan for 1998 a risk of Zincpyrithione that is being used as a component of dandruff treatment, it is thought that the aroma oil that was known for having an anti-dandruff effect has a merit of being easy in a user's access, thus it will be effective in curing the symptom of dandruff. Accordingly, this study conducted the following experiment in a bid to examine whether the aroma oil has the anti-microbial effect on the actual malassezia. First of all, it measured the minimum concentration of aroma oil in which the growth of malassezia is inhibited, by carrying out MIC(Minimum Inhibition Concentration) test in terms of anti-microbial activity against Malassezia furfur KCTC 7744 while using oils of Patchouli, Rosemary, Lavender, and Tea tree among aroma oils that are being used for dandruff treatment. As a result of that, Tea tree oil has the most excellent anti-microbial activity, and the measurement result of anti-microbial activity was shown in order of Lavender oil>Rosemary oil>Patchouli oil. Next, it carried out the is actually eased by applying Tea tree oil directly to the scalp of dandruff. In consequence of the experiment, the massage of Tea tree oil indicated the result of relieving the symptoms of dandruff such as scale, itch, pain, inflammation, and sebum, and among these symptoms of dandruff, it was shown to be most effective in easing itch. Especially, this clinical experiment was indicated that the massage of Tea tree oil has the most effect on relieving itch of targets with a dry-skin type who had no experience of dandruff treatment.

동충하초(Cordyceps)는 B.C. 2,000년 이후로부터 지금까지 중국, 한국, 일본 등 아시아 국가에서 잘 알려진 전통적인 불로장생의 비약으로 사용되어져 왔다. 곤충기생 곰팡이균으로서 원조 동충하초로 불리는 Cordyceps속에 속하는 Cordyceps sinensis는 우리나라 한반도에서는 발견되지 않고 있다. 그 이유는 해당 곰팡이균에 특정적인 기주곤충인 박쥐나방(Hepialus armonicanus)이 우리나라에는 존재하지 않기 때문으로 보인다. 따라서 차선책으로서 한국형의 동충하초, 즉 Paecilomyces tenuipes 동충하초균에 대한 곤충생체배지로서 누에(Silkworm, Bombyx mori)를 기주곤충으로 사용하는 누에동충하초의 인공적인 생산방법을 세계 최초로 개발하게 된 것이다. 따라서 본 총설은 누에동충하초를 개발하게 된 역사적 배경과 생산방법 및 약리학적 효능과, 비곤충유래 동충하초인 인공배지 배양동충하초(밀리타리스동충하초: Cordyceps militaris, 붉은자루동충하초: Cordyceps pruinosa 등)의 배양조건과 동충하초 품종육성, 배지배양조건, 동충하초의 식품에의 응용 가능성, 화학적 구성성분 및 약리적 효능 등에 대해 고찰하였다. 곤충유래의 누에동충하초 및 비곤충유래동충하초균사체 및 자실체동충하초의 주요 약리작용은 항종양, 면역증강, 항피로, 항스트레스, 항산화, 항노화, 항당뇨, 항염증, 항혈전, 항지질 및 해충방제 효능으로 요약된다. 동충하초의 주요 생리활성물질들은 단백다당체(헥소스, 헥소사민), 코디세핀, 만니톨, 산성다당체 등이다. 단백다당체와 부타놀 추출물은 매우 강한 항종양 효과를 보이나 세포독성은 나타내지 않았다. 만니톨은 종양유발쥐의 수명을 유의성 있게 연장하였다. 에르고스테롤은 항종양 활성은 보이지 않았으나 왕성한 식세포활성을 보였다. 따라서 우리가 높은 관심을 가지고 있는 누에동충하초의 항종양 활성은 세포독성효과보다는 면역력증강효과에 기인하는 것으로 사료된다[164].

The present study investigated the effects of Hovenia Dulcis (HD) fruit extract powder on the improvement of physical activity, especially exercise capacity. Forty mice were divided into 4 groups including normal controls, negative controls, 100 (HD-100) and 200 (HD-200) mg/kg HD fruit extract powder groups for 5-times exercises using treadmill. Normal control did not performed treadmill running but others did 5-times for 10 days. HD fruit extract powders were administrated orally one-times per day for 10 days before treadmill exercise and normal and negative controls were fed with excipient water. After 5-times exercise, blood biochemical analysis showed that aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and creatine phosphokinase (CK) activities and blood lactate concentration were statistically increased in negative controls than in normal controls. They were decreased in HD fruit extract powder groups, compared with negative controls. These results were considered as the effects of HD fruit extract powders on reduced tissue damages during exercise. Other measured indices did not reveal remarkable differences. All together, these results suggest that HD fruit extract powders may enhance the exercise performance by recovering the exercise-fatigue via blood lactate concentration by reducing blood LDH activity and via reduction of blood CK and AST activity.

The hot water extract of leather carp (Cyprinus carpio nudus) has been used as a nourishing tonic soup and as an aid for recovery from physical fatigue. In this study, we investigated the effect of leather carp extract on exercise performance in mice. Swimming endurance and forelimb grip strength were assessed following oral administration of the extract (once per day for 7 days) at a dose of $0.5 mg/10{\mu}L/g$ body weight. After 7 days, mice given the leather carp extract had significantly greater swimming endurance [$105{\pm}18s$ (P<0.05); 52% longer than day 0] and forelimb grip strength [$1.18{\pm}0.05$ Newton (P<0.01); 17% greater than day 0]. The extract increased muscle mass, but had little effect on body weight. Following the swimming exercise, blood glucose, glutathione peroxidase, and superoxide dismutase levels in extract-fed mice were significantly higher (145%, 131%, and 106%, respectively) than in the saline control group. Blood levels of high-density lipoprotein cholesterol were also significantly increased (128%) in mice given the extract compared to the controls. These results suggest that leather carp extract can improve physical exercise performance and prevent oxidative stress caused by exhaustive workouts.

BACKGROUND/OBJECTIVES: Mediterranean diet is an environmentally friendly and healthy diet model. The diet offers many vegetables, fruits, nuts, and olive oil to consumers. In addition, it provides moderate amounts of fish and chicken, smaller quantities of dairy products, red meat, and processed meat. The Mediterranean diet has a high anti-inflammatory and antioxidant content, and it causes many physiological changes that can provide a physical performance advantage. This study examined the effects of a 15-day menu, which was planned using foods with a low acid load within the Mediterranean diet rules, on the exercise performance, lactate elimination, anthropometric measurements, and body composition. SUBJECTS/METHODS: Fifteen professional male athletes between the ages of 13 and 18, who were engaged in ski running, were included in the experimental study. Dietary intervention was applied for 15 days. The athlete performances were evaluated by applying the vertical jump test, hand grip strength, 20 meters shuttle run test, and Borg fatigue scale. After the shuttle run test (every 3 min for 30 min), blood was drawn from the finger, and the lactate elimination time was calculated. Performance and lactate measurements, body analysis, and anthropometric measurements were taken before and after dietary intervention. RESULTS: The vertical jump height and hand grip strength increased after the intervention (P < 0.05). The test duration, total distance, the number of shuttles, and maximum oxygen consumption parameters of the shuttle run test increased (P < 0.05). After the intervention, the athletes' perceived fatigue scores decreased in several stages of the shuttle run test (P < 0.05). The lactate elimination time and athlete's body composition were similar in repeated measurements (P > 0.05). In the last measurements, the upper middle arm circumference decreased while the height of the athletes increased (P < 0.05). CONCLUSIONS: These results show that the Mediterranean diet is a safe and feasible dietary approach for aerobic performance and strength increase.

Objectives : Ojeok-san (OJS), an oriental herbal formula, has been used in Asian countries including Korea, China and Japan to treat the common cold and illnesses including fatigue and gastrointestinal disorders. The purpose of this study was to examine the anti-obesity effect and molecular mechanism of OJS, on adipogenesis in 3T3-L1 cells. Also, the effects of OJS in obese mice fed a high-fat diet on adiposity were examined.Methods : Preferentially, we analyzed the component of OJS and measured the stability of its component in OJS according to study periods using high performance liquid chromatography (HPLC). In vitro, 3T3-L1 cells were treated with OJS (50 to 200 μg/mL) during differentiation for 8 days. The accumulation of lipid droplets was determined by Oil Red O staining. The expressions of genes related to adipogenesis were measured by RT-PCR and Western blot analyses. For anti-obesty effect in vivo, we experimented for 8 weeks with four group (normal diet (CON), high-fat diet (HF), high-fat diet with OJS (HF+OJS) and high-fat diet with Bang-pung-tong-sung-san (HF+BTS) in comparison group HF+OJS).Results : OJS showed inhibitory activity on adipocyte differentiation at 3T3-L1 preadipocytes without affect cell toxicity as assessed by measuring fat accumulation and adipogenesis. In addition, OJS significantly reduced the expression levels of several adipocyte marker genes including proliferator activated receptor-γ(PPAR-γ) and CCAAT/enhancer-binding protein-α(C/EBP-α). Also OJS-administered mice showed significant inhibitory of body weights and abdominal adipose tissue weights.Conclusions : This study showed that traditional medicine OJS has an anti-obesity effect in vitro and in vivo. Thus, OJS could be developed as a supplement for reduction of body weight gain induced by an obesity.
