모발의 색은 melanin의 종류와 양에 의해 결정 된다. Melanocyte는 주로 자외선 자극에 의하여 L-tyrosine으로부터 멜라닌을 합성한다. 활성산소종은 백발의 진행과정에 중요한 역할을 하고 있다. 적하수오는 백발화되는 노화과정을 억제한다고 보고되고 있다. 본 연구의 목적은 흑모발생과 연관된 melanin 합성에 대한 적하수오 에탄올 추출물(PMEE)의 효능을 조사한 것이다. 항산화 실험에서 PMEE는 DPPH radical을 감소시켰고 환원력을 증가시켜 PMEE는 백발과정에 관여하는 활성산소종을 소거할 수 있다고 볼 수 있다. PMEE는 농도 의존적으로 세포생존능을 감소시켰다. 더욱이 melanin의 생성에 대한 PMEE의 효과는 DOPA assay와 tyrosinase 활성측정에 의하여 결정되었다. PMEE는 tyrosinase 활성을 증가시켰으며 melanin 합성을 촉진시켰다. 뿐만 아니라 Western blot 분석을 이용하여 tyrosinase, TRP-1, TRP-2 및 MITF 뿐만 아니라 SOD-3와 catalase와 같은 항산화 효소의 단백질 발현을 조사하였다. PMEE의 항산화 활성의 증가로 인하여 SOD-3와 catalase의 발현 수준은 감소된 것으로 나타났다. 특히, PMEE는 tyrosinase와 TRP-2의 발현 수준은 증가시켰다. 이러한 결과들은 PMEE가 백발화 된 모발에서 흑발로 변하는 것과 관련된 melanin 합성을 촉진할 수 있다는 것을 암시하고 있다.

Ginsenoside Rg4 is a rare ginsenoside that is naturally found in ginseng, and exhibits a wide range of biological activities including antioxidant and anti-inflammatory properties in several cell types. The purpose of this study was to use an in vivo model of hair follicle (HF)-mimic based on a human dermal papilla (DP) spheroid system prepared by three-dimensional (3D) culture and to investigate the effect of Rg4 on the hair-inductive properties of DP cells. Treatment of the DP spheroids with Rg4 (20 to 50 ㎍/ml) significantly increased the viability and size of the DP spheres in a dose-dependent manner. Rg4 also increased the mRNA and protein expression of DP signature genes that are related to hair growth including ALP, BMP2, and VCAN in the DP spheres. Analysis of the signaling molecules and luciferase reporter assays further revealed that Rg4 induces the activation of phosphoinositide 3-kinase (PI3K)/AKT and the inhibitory phosphorylation of GSK3β, which activates the WNT/β-catenin signaling pathway. These results correlated with not only the increased nuclear translocation of β-catenin following the treatment of the DP spheres with Rg4 but also the significant elevation of mRNA expression of the downstream target genes of the WNT/β-catenin pathway including WNT5A, β-catenin, and LEF1. In conclusion, these results demonstrated that ginsenoside Rg4 promotes the hair-inductive properties of DP cells by activating the AKT/GSK3β/β-catenin signaling pathway in DP spheres, suggesting that Rg4 could be a potential natural therapy for hair growth.

Objectives : The purpose of this study was to investigate correlation between obese degree, result of hair tissue mineral analysis and bony maturation. And we also wanted to compare the differences between early bony maturation group(EBM) and late bony maturation group(LBM). Methods : 146 subjects who visited growth clinic were measured by BMI, PBF(percent body fat), percent BMI, bone age esimation and HTMA(hair tissue mineral analysis). The patients were classified into two groups - EBM, LBM group - according to the gap of bone age and chronological age. It was analysed that the correlation of bony maturation and obese degree, nutritional elements, heavy metals, significant ratio of nutritional elements. Also, analysed the differences between groups. Results : 1. BMI, percent BMI had a correlation with bony maturation, PBF however didn't have a correlation with it. 2. Ca, Mg, Zn and P had a positive correlation with bony maturation, and also K, Cr and Mo had a negative correlation. 3. U, As and Cd had a negative correlation with bony maturation. 4. Ca/P, Na/K, Ca/K and Zn/Cu had a positive correlation with bony maturation, and also Na/Mg, Ca/Mg had a negative correlation. 5. Percent BMI, Ca, Mg, Mn and Ca/p were higher in EBM group. 6. K, Mo and Hg were lower in EBM group. Conclusion : According to this study it could be suggested that maintaining proper percent BMI and accumulation of nutritional elements, heavy metals to prevent early bony maturation.
