Background: This study was conducted to evaluate the effects of pharmacopuncture and dermal application of Sebalgukhwa-san extracts on hair growth in an alopecia mouse model. Methods: Twenty-one C57BL/6 mice were divided into 3 groups; control group-normal saline injection or vehicle solution application, positive control group-minoxidil (MNXD), experimental group-pharmacopuncture and applied Sebalgukhwa-san (SGS) extract. The effects of the treatment on hair growth, were determined through photographs, and phototrichogram analysis by folliscope. Hair follicle morphometry by hematoxylin-eosin staining was performed, and hair growth-related protein expression of vascular endothelial growth factor, insulin like growth factor-1, and transforming growth factor-beta 1 were monitored by Western blotting. Serum levels of aspartate aminotransferase and alanine aminotransferase were measured for liver function test. Results: Body weight increased consistently in all groups. Hair growth was improved in the MNXD and SGS groups compared with the control. Hair density and thickness improved statistically significantly in the MNXD and SGS groups compared with the control p < 0.05. The number of hair follicles improved in the MNXD and SGS groups compared with the control but the size did not. The expression of vascular endothelial growth factor and insulin like growth factor-1 increased, and there was a decrease in the expression of transforming growth factor-beta 1 in the MNXD and SGS groups compared with the control, however, there was no significant difference. Sebalgukhwa-san treatment had no toxicity in liver function tests. Conclusion: Pharmacopuncture and dermal application of Sebalgukhwa-san extract may be therapeutically beneficial for the treatment of alopecia.

Determination of several cationic surfactants in cosmetics has been investigated. Reverse phase ion pair chromatography was used to identify and quantitate cationic surfactants. Cationic surfactants analyzed in this experiment were cetylpyridium chloride, stearyltrimetylammonium chloride, bezalkonium chloride, benzyldicethylcetylammonium chloride, and bihenyltrimethyl ammonium chloride. The separation was achieved on a reverse phase coumn with 10mM HCl-acetonitrile eluent. In this condition, the most of cationic surfactants with exception of CPC and CTAC respectively with suppressed conductivity detector and UV detector connected in series. The calibration curves obtained by plotting the peak areas of the cationic surfactants were linear at levels ranging from 0.005 to 0.1% correlation coefficient, r=0.9988. The detection limits were 1 to 5ppm in sample solution. The average recoveries of cationic surfactants added to hair treatment cream and hair rinse in three to five experiments were 96.7 105.2% and relative standard deviations were 1.1-3.8%. The case that there were CPC and CTAC in same solution was also tested. CPC and CTAC which couldn't be separated on reverse phase column were quantitated with suppressed conductivity detector and UV detector connected in series. Recovery of CPC and CTAC were 101.6 and 89.2% respectively. The proposed method was applied to the determination of cationic surfactants in commercial hair treatment cream.

To overcome the harmful effects caused by conventional oxidative hair dyes, natural colorants becomes more popular in the hair dyeing. By extracting Sagassum fusiforme powders with aqueous alkaline solution as a solvent at 130℃ for 60 minutes, a fucoxanthin concentration of up to 216㎍/ml can be obtained. UV/Vis analysis was used to prove the presence of fucoxanthin in the extract powder. A K/S value of 23.8 can be obtained when wool fabrics were dyed with the extract at 120℃ for 60 minutes under pH 2. The color fastness properties of the dyed wool fabrics were very good as indicated by rating 4 for laundering(color change), rating 3 or higher for rubbing, and rating 5 for light irradiation. The dyed wool fabric was found to have antimicrobial activity against Staphylococcus aureus. The antioxidant and antimicrobial activity of the Sagassum fusiforme extract can be an effective functional hair colorant. Hair dyeing with the extract formulation at 45℃ for 40 minutes under pH 5 accomplished a K/S value of 8.9. The color fastness of the dyed hair showed rating 3 against light irradiation, which increased to rating 5 with after-mordanting of tannin acid.

예전부터 치약이 모발성장을 촉진시킬 수 있는 잠재력을 갖고 있다고 제안되어 왔지만 발모효과에 대한 과학적 검증과 치약 내 주요 활성성분에 대한 연구는 보고된 바가 없다. 따라서 본 연구에서는 치약을 이용하여 피부 각질세포의 성장 및 C57BL/6 마우스의 제모된 등쪽 피부에 국소적으로 적용하여 모발의 성장 촉진 여부를 평가하였다. 본 연구 결과 치약의 구성 성분으로서 문헌에서 발모 효과가 있다고 알려진 𝛼-tocopherol acetate와 l-menthol, stevioside 혼합액과, 이들을 제외한 치약 조성 성분들의 혼합액을 각각 두 그룹의 C57BL/6 마우스의 제모된 피부에 국소적으로 적용한 경우, 치약 성분의 혼합액은 발모효과를 보이지 않았고, 𝛼-tocopherol acetate과 l-menthol, stevioside 혼합액이 포함되었을 경우에는 마우스에서 발모 효과가 나타났다. 따라서, 치약을 구성하는 보조성분들인 α-tocopherol acetate과 l-menthol, stevioside 혼합물은 in vivo에서의 모발성장에 있어 잠재력을 갖고 있음을 확인하였다. 또한 치약을 처리한 그룹의 마우스와 발모 유효 성분으로 추정되는 𝛼-tocopherol acetate과 l-menthol, stevioside를 혼합 처리한 그룹의 마우스, 그리고 대조군의 마우스의 등쪽 표피를 취하여 전사체 분석을 진행한 결과 대조군에 비해서 각각의 처리군에서 유의적으로 발현된 유전자 패턴은 매우 유사함을 보였다. 또한 기능유전체적 분석을 하였을 때, 두 그룹에서 공통적으로 발모 조절 관련 기능의 유전자들이 매우 큰 비율의 변화를 보였다. 두 그룹에서 발현이 변화한 발모관련 유전자들로는 케라틴과 케라틴 관련 단백질, forkhead box, sonic hedgehog 등이 관찰되었다. 따라서, 치약의 발모 효과는 𝛼-tocopherol acetate과 l-menthol, stevioside 혼합물의 효과에 기인하는 것으로 생각된다.

The aim of this study was to investigate the effect of charge carrier lipid on the skin penetration, retention, and hair growth of topically applied finasteride-containing liposomes. Finasteride-containing liposomes were prepared by traditional thin film hydration method using Phospholipon$^{(R)}$ 85 G and cholesterol with or without charge carrier lipid (1,2 dimyristoyl-sn-glycero-3-phosphate or 1,2-dioleoyl-trimethylammonium-propane for anionic and cationic charge, respectively). Freshly prepared finasteride-containing liposome suspension was applied on the hairless mouse skin, and skin penetration and retention were measured using Keshary-Chien diffusion cell. Non-liposomal formulation (ethanol 10% solution containing 0.5 mg/ml of FNS) was also used as a control. The amount of finasteride in the diffusion cell and mouse skin was measured by HPLC. The hair growth was evaluated using depilated male C57BL/6N mice. Mean particle size of all finasteride-containing liposomes was less than a micron, and polydispersity index revealed size homogeneity. Skin penetration and retention studies showed that significantly less amount of finasteride was penetrated when applied as anionic liposome while more amount of the drug was retained. Specifically, in liposome prepared with 10% anionic charge carrier lipid, penetration was 12.99 ${\mu}g/cm^2$ while retention was 79.23 ${\mu}g/cm^2$ after 24 h of application. In hair growth study, finasteride-containing anionic liposomes showed moderate efficacy, but the efficacy was not found when applied as cationic liposomes. In conclusion, topical application of finasteride using anionic liposome formulation appears to be useful option for the treatment of androgenetic alopecia to avoid systemic side effects of the drug.

A new method was developed to prepare microcapsules involving hydrophobic components. A totally new "silicone-resin-polypeptide" was used as the wall materials. The polypeptide was made by hydrolysis of collagen and silk protein and so on, and that was combined with silicone. This microcapsule was easily prepared from silicone-resin-polypeptide in water solution. The ratio of encapsulation in the microcapsule was not only high level as 90％, which had never been reached, but also the particle size could be controlled to obtain very small size (average particle size: 2${\mu}{\textrm}{m}$). Moreover, these microcapsules were resistant to high shearing forces and were stable over a long time period. This stable microcapsule was not crushed in pressure with finger spreading, so the core materials hardly touch the skin directly. Application in cosmetics by using microcapsule involving UV absorbents (2-ethylhexy1-4-methoxycinnamate (OMC) and 4-tert-butyl-4' -methoxydibenzoyl-methane (BMDBM)) was examined. It was possible to apply organic UV absorbents in water-rich formulations without any surfactant by using this microcapsule. This formulation demonstrated a good moisturizing and soft skin feel. Therefore, the microcapsule was applied to hair care products. As a result, the sunscreen hair lotion with microcapsule was able to prevent from damaging and decoloring of hair color by UV rays. As just, it was suggested that this microcapsules were be widely applied in cosmetics.cosmetics.
