Cortex Mori radicis has been used as a components of antidiabetics, antiasthma and diuresis in Oriental Medicine. This experiment examined the effect of an extracts, obtained from the acetone(CM-A) and aqueous(CM-W) extracts of Cortex Mori radicis, on hair growing activity of the C57BL/6N mice after topical application to skin. We investigated the number of hair follicle and mast cells, and changes of subpopulation of splenocytes and thymocytes in skin for 16 day. The results were as follows : The Hair growing effect in experimental groups was more increased in 85%(CM-A) and 90%(CM-W) than control group(10%) in hair depilated area. The number of hair follicle in experimental groups(CM-A and CM-W) was more increased than control group. Splenic B/T lymphocytes of CM-A group were decreased compare to control group. CD4/CD8 positive TH cells in splenic T lymphocytes of CM-W group were increased compare to control group. These results suggest that CM-A and CM-W may be used in treatment of alopecia areata.

Ultrastructural and cytochemical studies of the root hair cell and the trichoblast were undertaken with light and electron microscopes to clarify the type of root hair, fine structure and the activities of acid phosphatase and ATPase. The root hair was differentiated from the middle portion of the cell, and perpendicularly to the long axis of the cell. Consequently, the type of root hair comes under the panicoid type. In the trichoblast, nucleus and cytoplasm are located in the vicinity of cortex. On the contrary, after the root hair is formed, they migrate to the apical region of the root hair, and the basal region of the root hair is filled with numerous vacuoles. Cell walls of actively growing root hairs are subdivided into two layers on the basis of the arrangement of cellulose microfibrils. New cell wall of the root hair is presumptively formed from Golgi complex-derived vesicles. Activity of acid phosphatase appeared on tonoplast, plasma membrane, and nuclear envelope, whereas ATPase activity appeared on the plasma membrane, heterochromatin, and mitochondrial cristae.

Backgrounds : Androgenetic alopecia is a relatively common disorder, but its precise mechanism is not elucidated. There are two commercial drugs approved by FDA. One(finasteride) has an inhibition activity of 5$\alpha$-reductase(type 2) and the other(minoxidil) has a vasodilation activity. Objectives : A verified herbal remedy for baldness is needed for medicinal treatment or preventing alopecia, which could be demonstrated by alopecia-related in vitro & in vivo tests Methods : On the basis of oriental pharmacognosy, we classified many herbal medicines into four groups (malnutrition, aging, alopecia and gray hair) according to its effect. The mitosis induction of hairy dermal papillae cell and the metabolic inhibition for type 2 $5{\alpha}-reductase$ were tested with five herbal extracts. Also, five herbal extracts were added to the normal essence formulation (HHRHG0202-80) in ranges of 0.1~0.3%, which was applied two-mouse models to validate each hair growing activity in vivo. Results : Stimulation of follicular papillae cell proliferation was observed in treatment of three herbal extracts (Glycyrrhizae radix:159.7%, Corni fructus : 144.7%, and Coicis semen : 136.6%) at a dose of $10\mu\textrm{g}/ml$. Three herbal extracts (Biotae semen. Glycyrrhizae radix and Coicis semen) showed inhibitory activity for $5{\alpha}-reductase$(type 2) at 93.18%, 73.36% and 47.6%, respectively at the same dose. We observed the enhancement of hair growth activity in C57b1/6 mouse and the inhibition of alopecia in AGA mouse after topical administration of the hair essence. Conclusions : Hair essence product, which contains five medicinal plants, would be used for the remedy for male pattern baldness (MPB) and the other alopecia diseases.

Objects : Glycine max Merr. (black bean), Triticum aestivum L. (wheat) and Oryza sativa L. (rice bran) have been widely used for treatment of relaxion of smooth muscle, gastrointestinal hemorrhage and alopecia in Korean Traditional Medicine. In this research, we examined the effect of the extracts, obtained from EtOH extracts of 3 kinds of traditional plants, on hair growing activity of the DP6 and C3H10T1 cell and physical properties. Materials and Methods : On the basis of previous studies, three traditional plants were selected and we extracted them with ethanol. We evaluated their hairy dermal papillar cell proliferation activity and mouse mesenchymal stem cell in vitro model. Also, 3 herbal extracts were added to the normal shampoo formulation in ranges of 0.1% and we validated tensile properties and physical changes using aged hair. In this research, we compared the tensile strength, shine and color appearance between the hair (general formulation) and the hair after applying shampoo with natural extracts. To analyze the luster and color image, we use the SAMBA hardware and software made by Bossa Nova Technologies. Results : In the comparative test for tensile characteristic between the hair treated general formulation(control) and the hair applying special formulation including 3 kinds of extracts, tensile distance and energy of the latter are larger than control on average. The shine and color appearance were also increased after using shampoo including natural extracts(shine : 10.9%, color appearance: 24.12%). We observed the enhancement of hair growth activity in the DP6 and C3H10T1 cell. Especially black bean extracts had the most powerful effect in the dermal papillar cell proliferation. Conclusion : These experiments suggest that extracts of Glycine max Merr. (black bean), Triticum aestivum L. (wheat) and Oryza sativa L. (rice bran) stimulate the hair growth activity and can improve physical activities of aged hair. Shampoo product, which contains 3 kinds of natural extracts, would be used for the treatment for aged hair.

Hair dyeing, hair perming, and daily hair dryer use can substantially damage hair. Consequently, the demand for products containing natural ingredients for the care of damaged hair is growing. Although polyphenols with antioxidant effects are often used for hair conditioning, few studies have focused on hair conditioning, and the potential of Sparassis latifolia mushroom extract for hair improvement has not been evaluated to date. In this study, the antioxidant activity of and polyphenol content in hot water, 70% and 100% ethanol (EtOH), n-hexane, ethyl acetate (EtOAc), and water extracts of S. latifolia were analyzed. A hair treatment containing S. latifolia extract was prepared, and its effect on damaged hair was evaluated. The highest antioxidant activity was observed in the hot water and EtOAc extracts. Moreover, polyphenol analysis using high-performance liquid chromatography and liquid chromatography-mass spectroscopy confirmed that the EtOAc fraction has relatively high contents of specific polyphenols beneficial for hair. Based on these results, a hair treatment containing S. latifolia extract was applied to damaged hair, and hair improvement was evaluated using hair thickness, tensile strength, and scanning electron microscopy. The hair treatment containing 70% EtOH extract effectively improved hair condition. We postulate that this improvement was caused by the high hydrophobic polyphenol content in the 70% EtOH extract.

A diarylheptanoid, (5S)-1,7-bis-(3,4-dihydroxyphenyl)-5-hydroxyheptane-3-one-5-O-${\beta}$-D-xylopyranoside, named oregonin (1), was isolated from the of Alnus japonica (A. japonica), which is a species of the genus Betulaceae, growing throughout Korea, Japan and China. The structure was elucidated by various spectroscopic methods including negative and positive LC/MS, 1H-NMR, and 13C-NMR techniques or by comparison with authentic samples. In order to evaluate the anti-oxidative activities of oregonin (1) isolated from A. japonica, 1,1-diphenyl-2-picryhydrazyl (DPPH) radical scavenging activity and 2,2'-azino-bis[3-ethylbenzothiazoline-6-sulphonic acid] (ABTS) radical scavenging activity were measured in vitro. Oregonin from A. japonica exhibited potent DPPH and ABTS radical scavenging activities. A. japonica shows not only 1,1-diphenyl-2-picryhydrazyl (DPPH) radical scavenging activity and ABTS radical scavenging activity, but also apoptosis modulative effects. The present results indicate that A. japonica could be a hair-growth-promoting agent for cosmetic products.

Dendropanax morbifera Leveille (Araliaceae) is an endemic species growing in the south-western part of South Korea and has been used in folk medicine. However, the effects of Dendropanax morbifera Lev. on skin biology remain to be elucidated. In this study, we isolated 1-tetradecanol and ${\beta}$-sitosterol from the n-hexane fraction of Dendropanax mobifera Lev. and To investigate the whitening effect of the fraction, we tested the inhibition of tyrosinase activity of 1-tetradecanol. The results show that the inhibitory effect of the 1-tetradecanol was higher than water extract and n-hexane fraction. And 1-tetradecanol significantly reduced melanin contents of B16F10 cells compared to more than water extract and n-haxane fraction dose-dependantly without cell cytotoxicitiy (below $100{\mu}g/mL$). We also investigated the skin moisturizing effect using HR-1 hairless mice. The transepidermal water loss (TEWL) in the 1-tetradecanol treated group was significantly smaller than that in the other groups. To investigate the effect of the preventing hair loss by ${\beta}$-sitosterol, we observed HR-1 hairless mice through periodic growth feature. The results suggest that hair loss of mice by ${\beta}$-sitosterol was delayed and it's hair density showed the highest. These data provide evidence that Dendropanax morbifera Lev. may be a potent candidate for the improvement of both skin whitening, moisturizing and alopecia from the point of cosmetic industry view.

Benign prostatic hyperplasia (BPH) is one of the most common diseases among elderly men. As the old-age population is increasing recently, it is to our interest to observe the growing BPH within them. In BPH, the dihydrotestosterone (DHT) acts as promotes prostate growth. It inhibits enzyme $5{\alpha}$-reductase that is involved in the conversion of testosterone to the DHT activity which reduces the excessive prostate growth. Through experiments, the effects of Phellius linteus water extract performed on the BPH rats were induced by testosterone treatments. For 12 weeks, Sprague-Dawley rats were treated with testosterone for the induction of BPH. Rats were divided into four experimental groups: the not treated group (N), the testosterone injection and D.W treatment group (TN), the testosterone injection and Phellinus linteus treatment group (TP) and testosterone injection and finasteride treatment group (TF). Prostate weight, volume and weight ratio in the TP group and the TF group were significantly lower than the TN group. Testosterone and DHT levels in the TN group were significantly higher than that of the N group. And the TP group was significantly decreased than that of the TN group. While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation; the TP and TF groups showed trophic symptoms and were lined by flattened epithelial cells, thus, the stromal proliferation is relatively low as compared to the TN group. These suggest that Phellinus linteus water extracts may be an useful remedy for treating the benign prostatic hyperplasia.
