천연 약용식물에 있어서 감마선 조사 처리는 기능성 물질탐색에 적용 시 추출수율 증진, 색상 개선 등 산업적 응용을 용이하게 하는 방법으로 활용이 기대되고 있다. 본 연구에서는 감마선 조사가 총목피 추출물의 생리활성에 미치는 영향을 검토하였다. 감마선 조사 처리한 총목피의 감마선 조사여부를 확인하기 위하여 광자극 발광(PSL) 및 열 발광(TL) 방법을 활용하여 감마선 조사 판별 확인시험을 진행하였다. PSL법의 경우 비조사구 0 kGy에서 400.00 PCs로 음성(negative) 시료로 판단되었으며, 조사구 5, 10, 30 kGy에서 각각 90,100.00 PCs, 312,614.33 PCs, 321,661.67 PCs로 나타나 감마선을 조사한 양성(positive) 시료로 확인되었다. TL법 적용 시 비조사구 0 kGy에서 자연방사선에 의한 $300^{\circ}C$ 부근에서 조사구 5, 10, 30 kGy는 $150{\sim}250^{\circ}C$의 부근에서 특유의 glow curve를 나타내었다. TL ratio는 비조사구 0 kGy에서 0.011로 0.1 이하의 값을 나타냈으며, 조사구 5, 10, 30 kGy는 각각 1.105, 1.009, 2.206으로 0.1이상의 값을 나타내어 조사구로 확인되었다. 감마선 조사처리한 총목피의 total phenolics 함량을 측정한 결과 0, 10, 30 kGy 선량 중 10 kGy의 조사선량에서 총목피 열수 및 50% ethanol 추출물의 total phenolics 함량이 각각 $17.30{\pm}0.40mg/g$, $18.87{\pm}0.46mg/g$으로 가장 높은 phenolics 함량을 나타내었다. 감마선 조사 처리한 총목피의 angiotensin converting enzyme 저해효과와 xanthin oxidase 저해효과는 비조사구에 비해 조사구에서 열수 및 50% ethanol 추출물 모두 증가하는 것을 확인할 수 있었다. Pancreatin ${\alpha}$-amylase 저해효과와 ${\alpha}$-glucosidase 저해효과는 총목피 열수 및 50% ethanol 추출물 $200{\mu}g/mL$ phenolics 농도 처리 시 0~30 kGy의 모든 선량에서 60~100%에 가까운 높은 저해율을 나타내어 현재 당뇨병 치료제로 사용되고 있는 acarbose와 비교 시 월등히 우수한 항당뇨 효과를 확인할 수 있었고, 이를 통해 감마선 조사 처리한 총목피 추출물은 천연소재로써 항당뇨 관련 기능성 소재로 유용하게 사용될 수 있을 것으로 판단되었다. 이상의 결과 총목피 추출물은 다양한 생리활성을 가진 기능성 소재로 활용이 가능한 것으로 생각되었으며 감마선의 조사에 의해서 총목피의 생리활성이 증대되는 현상을 확인함으로써 감마선 조사가 식물체가 나타내는 생리활성을 증폭시킬 수 있는 수단으로 활용이 가능할 것이라 판단되었다.

1. Ounyukki(五運六氣) theory was first developed from observation of astronomical phenomena. Natural phenomena were explained and incorporated into the concepts of Yukki(六氣), and Ohaeng(五行, the concept that all matter in the world are comprised of five fundamental elements), during Chon-guk(戰國) and Han(漢) periods. In that period. Kanji(干支, the method to present time with ten and twelve different kinds of symbol's combinations) was used to record Ounyukki(五運六氣). Theoretical study of Un-gi(運氣, the abbreviation of Ounyukki) was almost completed in Un-gichilpyon(運氣七篇) of Naekyong(內經). Un-gi(運氣) theory was further studied and considered to be very important socially, as well as medically, in Tang(唐), Song(宋), Kum(金), and Won(元) periods. Hagan(河間) published various studies based on Un-gi(運氣) theory in Kum won(金元) periods. 2. Hagan(河間) realized the limitation of a remedy method, of Sanghan(傷寒) theory. Therefore, he made an assumption that the prevalence of diseases in his period are closely related to Hwayol(火熱, a fire and a super-heat; two things out of Yukki(六氣)). His new theory was a result of the study on Kyongjon(經典, bibles of the oriental medicine) and the phenomena of nature. 3. Hagan(河間) used a combination of two basic theories of Pimuripsang(比物立象) and Hanhaesungjeron(亢害承制論) to make understood Hwayol(火熱) theory, Pimuripsang(比物立象) theory explains a method to appreciate the essence of things by comparing Sang(象, an expression of how something appears on the outside) and then making another Sang(象) from the comparison. Hanhaesungjeron(亢害承制論) is a theory to emphasize the importance of a balance of Yukki(六氣). It is that, if one of the elements is exceeded, other thing in the other five elements dominate the exceeded thing to control it for the balance between Yukki(六氣). In addition, he articulated P'yobon(標本. inside and outside of a thing) theory to differentiate the disease symptoms. These theories will help to distinguish real and fake symptoms of diseases, on which Hagan(河間) emphasized its importance. 4. Hagan(河間) published a new theory to explain Ounyukki(五運六氣) theory based on the observation of the nature and the experience from medical practice. And he added Chobyonggi(燥病機, course and rule causing disease in dry conditions) to Pyonggishipkujo(病機十九條, nineteen course and rule causing disease), it strengthened Pyonggi(病機, course and rule causing disease) theories. Moreover. he utilized Un-gi (運氣) theory in a real life situation by applying Un-giron(運氣論) to diagnosis like Maekchin(脈診, a method to diagnose by taking the pulse) and to prescription. 5. Modern society is an era in which it is hard to appreciate the principles of the changes due to the various unusual weather. Therefore, it is necessary to make a new paradigm using Un-gi(運氣) theory, like Hagan(河間) did in Kumwon(金元) period. 6. Unusual weather changes and the geriatric diseases such as cancer and diabetes, may have Sang(象) of Hwayol(火熱) theory at the other side. These diseases have been and will create more serious problems in modern society. As a method to solve these problems. it seems to be very important to understand and apply Hagan's(河間) Hawyol(火熱) theory to modern society.

It is considered to be important to create aesthetically beautiful style through the change of external shape, however for the hair stylists, whose beauty expression is through hair, the role of hair doctor is becoming even more important with focus to improve the hair healthiness. Hair clinic is management of hair and scalp. It is the management process of preventing damages, while improving and cultivating healthy and shiny hair. The current concept in hair management is moving from simple hair styling to emphasis at hair management. As far as hair management is concerned, it usually includes treatment tools such as shampoo, conditioner, hair treatment and scalp scaling system, which is used for diagnosis of hair condition in order to treat the scalp. As the interest of hair healthiness becoming more wide spread, so does the breadth of clinic menu. The wide choice is to fulfill the profound desire of people, whose demands are simply to have variety in their choice. This is resulting in faucets of new value-added and differentiated products. The values that make-up the hair styles consist of mainly design (trend, preference), function(styling, management convenience) and clinic(hair quality improvement, damage repair). Shampoo and conditioner have gone beyond their original function of cleansing to providing combinational functions of treatment, to care and remedy, and advanced massage effectiveness. These are, to name a few that seem to go beyond their original function to satisfy the mental healthiness in people, the King Kong shampoo of shampooings in forward-backward manner, 5-minute shampoo massage that applies sports and relaxation massage, scalp acupunctural message and aural(ear) massage. More and more people are complaining about the damaged hair and hair loss problems due to perms, dyeing and bleaching of hair, in addition to natural scalp and hair damaging factors. Such complaints have stimulated many beauty products and various hair treatment systems being introduced with focus to provide nutrition and prevent damages to scalp and hair. As the living standards improve and the desire of people is to pursue differentiated lives, their demand also increases in hair styling products to fulfill the needs of healthy and aesthetical aspects of their lives.

Gami-Sopungsan (GS) is one of the traditional korean remedy. We investigated the anti-inflammation and anti-atopic dermatitis (AD) effect of GS. No cytotoxicity of GS was observed in the range of $1{\sim}100{\mu}g/m{\ell}$ on Raw 264.7 cells. The Inflammatory response of Raw 264.7 cells were induced by lipopolysaccharide (LPS), followed by GS treatment at indicated concentrations (0, 1, 10 and $100{\mu}g/m{\ell}$). At $100{\mu}g/m{\ell}$ concentration, GS showed inhibitory effect on LPS-induced nitric oxide production by 20%. Production of IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ was decreased by approximately 56%, 36% and 79%, respectively upon GS treatment at $100{\mu}g/m{\ell}$. 200 mg/kg of GS was orally administered to NC/Nga mice, where AD was induced by 1-chloro 2,4-dinitrobenzene. There were no significant difference between GS treated group and the control group on body weight and food intake changes during growth. The back skin of GS group showed decrease in erythema, pruritus, dry skin, edema, excoriation, erosion and lichenification level through naked eye observations. In addition, leukocyte infiltration and the thickness of epidermis were significantly decreased in the skin tissues (back and ear). The serum IgE levels were decreased by 28.8% in the GS treated group. The GS treated group showed remarkable inhibition of IL-4 (83%), IL-5 (95%), IL-6 (62%) and TNF-${\alpha}$ (84%) in serum, indicating that GS has similar or higher efficacy than those of the dexamethasone treated group. From the results above, we conclude that GS has significant anti-inflammation and anti-AD effects on Raw 264.7 cells and NC/Nga mice. The results should provide fundamental and valuable data for the research on natural products being developed against atopic dermatitis.
