Dermal papilla cells (DPCs) are present throughout the hair cycle and play an essential role in hair cycle and hair growth. In this study, we investigated the effect of Carex dispalata on the activation of anagen pathway in DPCs. C. dispalata extract increased the proliferation of DPCs and induced changes in the levels of cell cycle-related proteins. To elucidate the mechanism by which C. dispalata extract stimulates the anagen pathway related to the proliferation of DPCs, we evaluated the effect of C. dispalata extract on the activation of Akt signaling. The increase in the level of phospho-Akt by C. dispalata extract was inhibited by PI3K inhibitor (wortmannin). Wortmannin reduced the effects of C. dispalata extract on the levels of cell cycle-related proteins and proliferation of DPCs. C. dispalata extract increased the levels of Wnt/β-catenin proteins. Wnt/β-catenin inhibitor (XAV939) inhibited changes in cell cycle, cell cycle-related proteins, Wnt/β-catenin proteins, and proliferation induced by C. dispalata extract. C. dispalata extract increased the level of autophagy protein (LC3I/II), and this change was inhibited by XAV939. These results suggest that C. dispalata extract can activate PI3K/Akt, Wnt/β-catenin, and autophagy pathways in DPCs to induce cell proliferation, and thereby promote hair growth phase.

최근 식품의약품안전처에서 그동안 의약외품으로 분류되었던 '탈모 증상 완화' 관련 제품이 기능성 화장품의 범주에 포함됨에 따라서 관련 산업계에 큰 관심 중 하나라고 할 수 있다. 본 연구에서는 기존 의약품들의 한계점인 부작용의 위험률이 적으면서 탈모를 과학적으로 조절시켜줄 수 있는 객관적인 근거를 제시할 수 있는 천연물 유래 신소재를 발굴하고자, 오리나무 가지로부터 분리한 oregonin은 강력한 활성산소종 소거능을 가지며 탈모와 연관성이 높은 모유두 세포의 사멸을 명확하게 조절함을 확인하였다. 결론적으로 oregonin을 포함한 오리나무 추출물은 두피에서 발생한 활성산소를 강력하게 제거하는 효능을 기반으로 하여, 산화적 스트레스에 의한 모유두세포의 사멸 억제 및 조절을 통하여 탈모방지 효과를 기대할 수 있는 천연 탈모 방지 및 양모 신소재로서의 개발가능성이 있는 것으로 확인하였다.

This study was conducted to evaluate the effects of Padina arborescens and 1-O-myristoyl-2-O-oleoyl-3-O-(α-D-glucopyranosyl)-glycerol(MOGG), its active component, on the prevention of hair loss. The P. arborescens extract and MOGG inhibited the activity of 5α-reductase, which converts testosterone to dihydrotestosterone(DHT), a main cause of androgenetic alopecia. When immortalized rat vibrissa dermal papilla cells were treated with MOGG, the proliferation of dermal papilla cells significantly increased. In addition, we found that the P. arborescens extract and MOGG could open the K_ATP channel, which may contribute to increase hair growth. Furthermore, MOGG promoted PGE₂ production in HaCaT cells. The results suggest that MOGG from the P. arborescens extract has the potential to treat alopecia via 5α-reductase inhibition, the proliferation of dermal papilla, the opening of the K_ATP channel and/or increase of PGE₂ production.

최근 몇 년 동안 탈모로 인해 우울증을 경험하는 인구가 증가하고 탈모 관련 치료법도 임상의학이나 외과적인 수술법과 같이 전문화되고 있다. 탈모 방지와 발모를 촉진하기 위한 시술법과 소재들이 있으나 그 효능, 효과가 뛰어나지 못하고 일부는 부작용을 동반하는 경우가 있다. 본 총설의 마이크로니들 시술법은 약물의 흡수를 촉진시켜주는 매우 작고 섬세한 니들을 이용한 시술법이다. 이 시술을 하는 동안 마이크로니들이 두피 내부로 약물의 흡수를 도와주는 마이크로 홀을 만들어 준다. 마이크로니들 시술 약물의 주요성분으로 대두 발효물질을 분석하였으며 대두 발효 소재는 탈모증에 항산화, 항안드로겐, 항혈전의 기능을 가진다. 대두 발효물의 흡수를 증가시켜주는 마이크로니들의 우수한 약물전달시스템으로 인하여 대두 발효물이 마이크로니들과 함께 사용될 때 복잡한 탈모기전에 더욱 효과적이다. 이 시술법은 탈모증을 방지하고 관리하며 개선시켜줄 수 있는 매우 유용한 두피케어법이며 일반적인 두피관리법 보다 더 빠른 효과를 나타낼 수 있어 차별화된다. 대두 발효물을 이용한 마이크로니들 시술법은 두피케어를 위한 진일보한 기술이다.

Korean Ginseng is a medicinal herb which grows naturally in korea. an ancient country situated in north-eastern Asia. Its medical use was already well known to herb doctors in this region about five thousand years ago since the effectiveness of korean ginseng has been recognized through practical use for a long time. Korean Ginseng has always been regarded as a devine cure. The name "Ginseng" can be found in various medicinal books. many of which were written as early as B.C. 100. In the records of many chinese medical books. dating from the inception of publishing, it was noted that Korean Ginseng was of the highest level of quality. Korean Ginseng originally grew in the mountains of korea. However, this wild Korean Ginseng(js called SANSAM) could not meet the ever-increasing demands. and from the 16th century. it has been cultivated on farms for mass processing and supplying in korea(js called INSAM). It was already recognized in korea a long time ago(B.C. 57 - A.D. 668) that Korean Ginseng possessed the qualities of panacea, tonic and rejuvenator, and had other medicinal properties as well. The effectiveness of Korean Ginseng is widely recognized among south-eastern Asians as well as Chinese. As its effect has been proved scientifically. Korean Ginseng is now becoming the ginseng for all human beings in the world. Korean ginseng is differently called according to processing method. Dried thing is Insam(white ginseng), boiled or steamed is Hongsam(red ginseng). 장뇌삼(long headed ginseng) is artificially grown in the mountain no in field for a long time. So the body is thin and some long. but ingredients are concentrated. Korean wild ginseng(SANSAM) is rare in these days but we developed cosmetic ingredient. The scientific name of Korean Ginseng is Panax Ginseng. It has acknowledge as a natural mysterious cure among the notheastern peoples. because of its broad medicinal application. The origin of the word" Panax" derived from panacea. a Greek word meaning cure-all. According to the classification method of herb medicines in the Chinese medicinal book. "God-Farmer Materia Medica(A.D. 483-496) korean Ginseng was described as the superlative drug: panacea. tonic and rejuvenator. We studied skin immunological effect. collagen synthesis. cell growth and whitening effect of SANSAM extract. IN cosmetics.. SANSAM extract had skin fibroblast cell growth effect. recover damaged skin in the sun and protect fine wrinkle. Also. In hair product.. inhibits hairless, white hair.its hairless, white hair.

Ferulic acid (FA) is a phytochemical with various bioactive properties. It has recently been proposed that due to its phytogenic action it can be used as an alternative growth promoter additive to synthetic compounds. The objective of the present study was to evaluate the growth performance, carcass traits, fiber characterization and skeletal muscle gene expression on hair-lambs supplemented with two doses of FA. Thirty-two male lambs (n = 8 per treatment) were individually housed during a 32 d feeding trial to evaluate the effect of FA (300 and 600 mg d^-1) or zilpaterol hydrochloride (ZH; 6 mg d^-1) on growth performance, and then slaughtered to evaluate the effects on carcass traits, and muscle fibers morphometry from Longissimus thoracis (LT) and mRNA abundance of β₂-adrenergic receptor (β₂-AR), MHC-I, MHC-IIX and IGF-I genes. FA increased final weight and average daily gain with respect to non-supplemented animals (p < 0.05). The ZH supplementation increased LT muscle area, with respect to FA doses and control (p < 0.05). Cross-sectional area (CSA) of oxidative fibers was larger with FA doses and ZH (p < 0.05). Feeding ZH increased mRNA abundance for β₂-AR compared to FA and control (p < 0.05), and expression of MHC-I was affected by FA doses and ZH (p < 0.05). Overall, FA supplementation of male hair lambs enhanced productive variables due to skeletal muscle hypertrophy caused by MHC-I up-regulation. Results suggest that FA has the potential like a growth promoter in lambs.

백모 발생은 연령이 증가함에 따라 모낭에 있는 melanocyte 수가 감소됨과 동시에 세포활성이 저하되고 동시에 과산화수소($H_2O_2$)가 축적되어 melanin 합성이 감소되어 진행된다. 본 연구의 목적은 흑미 주정추출물인 Black oryzasativa ethanolic extract (BLEE)가 백모에서 흑모로 전환되는데 관련되어 있는 melanin 합성에 어떠한 영향을 미치는지 알아보고자 하였다. 본 연구에서 사용된 BLEE는 DPPH radical scavenging assay 및 환원력 실험에서 $64{\mu}g/ml$에서 항산화 효과가 있는 것으로 나타났으며, tyrosinase 활성 및 melanin 생성 촉진효과는 $16{\mu}g/ml$ 이상에서 효과가 나타났다. DCF fluorescence assay에서 세포내 $H_2O_2$를 소거하는 효과가 있는 것으로 나타났고, $H_2O_2$를 처리한 세포에서 melanin 생성 촉진효과가 있는 것으로 나타났다. 그러나 Western blot 분석에서는 catalase의 발현을 감소시키는 것으로 나타났으며 melanin 생성에 관여하는 tyrosinase, TRP-1, TRP-2, 효소 및 MITF 전사인자의 발현촉진에는 영향이 없는 것으로 나타났다. 그러므로 BLEE의 melanin 생성 촉진효과는 tyrosinase 활성 증가와 세포내 $H_2O_2$의 생성을 감소시켜 melanin 생성을 촉진시키는 것으로 나타났다. 결론적으로 BLEE는 melanin 생성을 촉진시키는데 있어서 중요한 역할을 하고 있는 것으로 확인되었으며, 본 연구에서 개발된 BLEE는 흑모성장과 연관이 있는 melanin생성 촉진과 관련된 모발화장품 개발분야에서 하나의 잠재적인 기능성 소재로 응용 될 수 있다는 것을 시사하고 있다.
