Objective : This study was carried out to investigate the effect of Hwangryeonhaedoktang pharmacopuncture solution (HRHDT) and microneedle therapy system (MTS) on hair growth in an alopecia model of C57BL/6N mice.Methods : Six-week old mice were depilated and separated in 4 groups ; CON (saline), MXD (3% Minoxidil), MTS and HRHDT+MTS. The treatments were applied twice a week for 17 days. The hair growth was determined photographically. The hair density, thickness and length were identified by Folliscope and the weights of body and organs were measured. In dorsal skin tissue, the expression of hair growth-related gene and protein was analyzed by RT-PCR. In addition, the hair follicles in the dermis were observed by H&E staining.Results : The promotion of hair growth was observed in HRHDT+MTS and MTS compared to CON. The hair density, thickness and length were also improved in HRHDT+MTS and MTS compared to CON. The mRNA expression of IGF-1, PRL and PL and the protein expression of VEGF and IGF-1 were increased in HRHDT+MTS and MTS compared to CON. The hair follicles and hair root growth were improved in HRHDT+MTS and MTS compared to CON. In the above results, HRHDT+MTS were more effective than MTS.Conclusions : These results suggest that HRHDT and MTS have a hair growth activity and can be useful for the treatment of alopecia.

Filiform hairs that respond to movements of the surrounding medium are the mechanoreceptors commonly found in arthropods and vertebrates. In these creatures, the filiform hairs function as a sensory system for raider detection. Parametric analyses of the motion response of filiform hairs are conducted by using a mathematical model of an artificial flow sensor to understand the possible operating ranges of a microfabricated device. It is found that the length and diameter of the sensory hair are the major parameters that determine the mechanical sensitivities and responses in a mean flow with an oscillating component. By changing the hair length, the angular displacement, velocity, and acceleration could be detected in a wide range of frequencies. Although the torques due to drag and virtual mass are very small, they are also very influential factors on the hair motion. The resonance frequency of the hair decreases as the length and diameter of the hair increase.

Generally, hair treatments by complementary actions to give a sense of activity are permanent setting, dyeing, and bleaching, etc. In this study, we investigated the wave formation ability and hair damage occuring in permanent setting and bleaching process. The wave formation ability was evaluated by the differences of length and curl diameter after permanent setting. And the hair damage was also evaluated by the protein release ability and SEM of hair. The bleached hair immediately after permanent setting treatment has better wave formation ability, but much more damaged than the bleached hair after rinsing thoroughly with warm water. It was considered that the chain of hair keratin broke down easily by the bleaching action in the existence of permanent setting agents.

Objectives : This study was carried out to investigate the effects of Crataegi Fructus water extract(CFWE) on hair growth in an alopecia model of C57BL/6N mice and human dermal papilla cells(hDPCs). Methods : Six-week old mice were depilated and separated in 3 groups ; CON, MXD(2% Minoxidil), and CFWE. The treatments were applied twice a day for 18 days. The hair growth was determined photographically. The hair density, thickness and length were identified by Folliscope and the weights of body were measured. In dorsal skin tissue, the expression of hair growth-related protein was analyzed by Western blot. In hDPCs with/without $IFN-{\gamma}$, cell proliferation and the expression of hair growth-related genes were analyzed. Results : We observed that CFWE promoted hair growth compared to CON. CFWE improved the hair density, thickness and length compared to CON. CFWE increased the $Wnt/{\beta}$-catenin signaling in dorsal skin. In hDPCs, CFWE accelerated the cell proliferation and inhibited $IFN-{\gamma}$-induced hDPCs degeneration. CFWE increased the mRNA expression of ${\beta}$-catenin, Axin-2, BMP-4, FGF-7, FGF-10, and ALP compared to CON and $IFN-{\gamma}$ treated cells. Conclusions : These results suggest that CFWE has a hair regrowth activity via $Wnt/{\beta}$-catenin signaling and can be useful for the treatment of alopecia.

Even it's not easy to in the cycle of the change without the qualification of the data, but we can try to figure out a cycle of change in fashion as Kroeber used content analysis. As content analysis with quantitative data increases the objectivity, especially in the case of highly complex materials like s appearance, multi-directional research method; quantitative and qualitative methods are combined in this study. In this research, first the change in hair length(HL), hair width(HW), hair height(HH) was examined to find out possible cyclic aspects of change in each elements and the significant relationships among the hair style was probed and the cyclic aspects between hair style elements and skirt style elements were compared. The data was analyzed by using Time series analysis and Pearson correlation coefficients. The statistical analysis of the hair style of 20th century showed that the hair style's elements changed independently and indicated the cyclic aspects in hair style as Kroeber's fashion cycle. To consider of this result, the hair style changed in a cyclic pattern, its pattern were different from skirt style's. And as hair style's change was affected by change, the hair styles change appeared during wars and disappeared during a social stabilization; this result supports social change theory.

Studies were Performed to determine whether the water fraction of Panax ginseng Protected radiation damage to hair medullar cells of N:GP(s) mice after in vivo irradiation with $^{60}Co{\;}{\gamma}-rays$. The hair follicles in the middle of the growth cycle were analysed 3 days after 3 Gy irradiation for the changes in the number of cells in the forming medulla of the hair in the region just above the germinal matrix of the growing (anagen) hair follicle. The radioprotective effect of ginseng was compared with the irradiation control. The medullar cell count per unit length ($100{\;}\mu\textrm{m}$) of hair follicle was higher in the pretreated-groups of ginseng, both oral (2 mg/ml of drinking water, p<0.05) and intraperitoneal (0.3 mg/head, p<0.001) treatments, than the irradiation control. These data suggested that the water fraction of Panax ginseng may reduce cell damages on the body surface caused by ${\gamma}-rays$.

Root hair development has the potential to increase crop yields and at the same time to decrease fertilizer use, which will be required in the next 30 years to meet the demand for crop-derived commodities in a world with decreasing available natural resources. Root hair defective six (RHD6) encoding a basic helix-loop-helix transcription factor, is associated with root hair differentiation, and its roles are root hair initiation and elongation. Grass plants, rice and Brachypodium have been used as model plants to study the gene function of the root hair defective six like (RSL) subfamily which is orthologous to AtRHD6. The RSL subfamily has an identical gene function with AtRHD6 which is involved with root hair differentiation as well. Plants with longer root hairs within a species should have an improved Pi uptake efficiency; therefore, we would expect that a plant with a high Pi uptake could contribute to increasing the plant yield. We achieved increased root hair length by manipulating the RSL subfamily genes. It is expected that in these transgenic plants, the long root hairs would be sufficient to improve the Pi uptake and hence improve biomass and yield component (tiller, spikelet number, and spikelet weight) of the plant. Here, we demonstrate that Brachypodium transgenic plants overexpressing the BdRSL subfamily genes have an improved biomass and grain yield. The result of this study could be applied to important crop plants like rice.

This study was aimed at giving help to the people intending to change hair fashion feeling for making their own hair style design and also providing the academic guide line to the cosmetic circles for developing new hair design and promoting sales by producing hair styles following the results from the statistical analysis based on the theoretical study on the face contour groups & hair fashion feeling groups. The researching methods were composed of following 3 steps ; prior theoretical research, statistical analysis, and hair style production. At first, the prior theoretical research was accomplished by analysis of literatures, magazines and internet sites about face contour, total & hair fashion feelings, hair style productions. Second, the prior statistical analysis were done about hairstyle images & their charateristics based on fashion feelings, and characteristics of fashion feeling group. And the third, hair style productions were done coordinated by face contours(oval, circle, long, square, reverse triangle) and hair fashion feelings(natural, sexy, sophisticate, ethnic, romantic pretty, elegance, sporty, avant garde) following the statistical results. But owing to the limitations to change hair length and color, these changes are modified by wigs and photoshop 7.0 program. So we could know there was no confirmed hair fashion feeling of one's best, but one could change one's hair fashion feeling and express one's beauty if one could adjust one's hair styles properly to one's face contour. This study would be very helpful to the people trying to change their own hair fashion feeling and be useful to the cosmetic circles for developing new design and promoting sales by comprehending hair design market and also be valuable to develop the methodology of 3 step research.
