  • In order to verify the effect of Sineungyangjin-Dan on alopecia, I experimented the hair regrowth of the normal mice and of the high butter diet-pretreated mice by feeding each group of mice a certain amount of ethanol extract of Sineungyangjin-Dan and water extract and thus obtained the results as follow; 1. The ethanol extract of Sineungyangjin-Dan was proved to promote the hair regrowth of the hair-removed normal mice. 2. 360mg/kg ethanol extract of Sineungyangjin-Dan was proved to have the effect of promoting hair regrowth by restraining the increase of free cholesterol and triglyceride but by helping the increase of free fatty acid in skin. As a result of the above study Sineungyangjin-Dan was proved to have the effect of promoting hair regrowth.

  • Objective : The purpose of this study is to report the hair regrowth effect of Gagamyeonryunggobon-dan on ICR mice from measuring the change of diverse factors.Methods : Gagamyeonryunggobon-dan was treated by oral administration with 2.5㎎/㎏/day amount for 3 weeks per mouse everyday. Hair regrowth was estimated by change of morphology, angiogenesis, hair follicle activation. The change of morphology was observed with external, internal change and sebaceous gland. Angiogenesis was estimated by image analysis, capillary distribution and angiogenic chemokine(MIP-2). Hair follicle activation was estimated by PCNA, IGF-2 and serotonin.Results : 1. Gagamyeonryunggobon-dan treated group had more and thicker hairs than the group not treated. Especially well developed sebaceous glands were seen in dermis of treated group. 2. Gagamyeonryunggobon-dan treated group had more capillaries near hair follicles of subcutaneous layer and more 2019% MIP-2 positive activity than the group not treated. 3. Gagamyeonryunggobon-dan treated group increased positive activity up to 596% in PCNA, 187% in IGF-2 and 547% in serotonin more than the group not treated.Conclusion : These results shows that Gagamyeonryunggobon-dan have the hair regrowth effect through verifying change of morphology, angiogenesis, chemokines. Consequently Gagamyeonryunggobon-dan is expected to apply to take care of extensive hair loss symptoms.

  • Morus alba has been well known for its tonic effect or preventing of hypertension, aging, or diabetes mellitus in Asian countries. To evaluate the its effect on hair growth promotion, we performed the hair regrowth experiment with leaf, branch, root and fruit extract of Morus alba on animal model of C57BL/6 mouse. The hair regrowth effect was remarkable in the mouse treated branch and root extract (with what %), however, little effect on hair regrowth appeared on the mouse treated with leaf extract. Morus alba extract displayed antibacterial effects on Bacillus subtilis, Staphylococcus aureus, Pseudomonas and Candida albicans. These results indicated that branch and root extract of Morus alba could be applicable for hair regrowth or prevention of hair loss in human.

  • Hwanggumgung (HGG) is a hair-care product which is composed of several plant extracts used in oriental medicine. This study was carried out to investigate effect of HGG on hair regrowth in a shaving model of C57BL6 mice. Five-week-old mice were acclimated for 1 week under 23$\pm$3$^{\circ}C$, 50$\pm10\%$ relative humidity and 12 h of a light/dark cycle before beginning experiment. There were four experimental groups including distilled water (D.W., control), 10$\%$ ethanol (EtOH, vehicle control), a positive control of 3$\%$ minoxidil (MXD), and HGG for female and male mice, respectively; Six-weeks old mice were trimmed by electric clippers so as not to damage the skin. The next day; mice without visible scraches were selected, randomized and separated in groups of 11 mice. The test compounds were topically treated with 0.15ml per mouse per day for 21 days. The hair regrowth was photographically and histologically determined during the experimental period of 21 days. Enzyme activities of $\gamma$-glutamyl transpeptidase and alkaline phosphatase were also determined using a rate assay method. There were no clinical signs in all experimental groups. The topical application of 3$\%$ MXD and HGG in female mice promoted hair regrowth earlier and faster than the control groups. In male mice, the topical application of 3$\%$ MXD and HGG also accelerated hair growth compared with the controls. Ten percent ethanol also promoted hair growth faster than D.W group. The histology of hair growth in experimental groups was strongly associated with the hair regrowth. 3$\%$ MXD and HGG promoted elongation of hair follicles compared with the controls in both female and male mice. Activities of alkaline phosphatase and $\gamma$-glutamyl transpeptidase, enzymes related to hair growth, significantly increased after treatments of 3$\%$ MXD and HGG for 2 weeks in both female and male mice (p < 0.05). These results suggest that HGG has hair growth promoting activities and it can be for treatment for alopecia.

  • Objectives : This study evaluates the hair growth promoting effect of Yonnyuniksoogobon-dan on shaved C57BL6 mice. Methods : Yonnyuniksoogobon-dan was administered orally (Group I) and both orally and by skin application (Group II) once a day for 12 days. The experimental groups were compared to Control, which was orally administered physiological saline solution. Hair regrowth was photographically and histologically determined during the experimental period. The levels of hair growth cycle related factors (EGF, TGF-${\beta}$1) and vascular factors (VEGF, iNOS) were also determined by immunohistochemistry. On gross observation of hair growth, both Group I and Group II shaved C57BL6 mice showed accelerated hair regrowth. Results : The hair regrowth index of Group I increased significantly from 7 days (P<0.05) to 12 days (P<0.01) after shaving and that of Group II was significantly higher at 12 days (P<0.05). On histological observation, both Group I and Group II demonstrated histological improvement and increases in the number and diameter of the hair follicles. EGF expression on the root sheath of hair follicles was up-regulated in both Group I and II. TGF-${\beta}$1 expression on the root sheath of hair follicles was unchanged in both Group I and II. VEGF expression in the tissues surrounding hair follicles was up-regulated in both groups. iNOS expression in the tissues surrounding hair follicles was down-regulated in both groups. Conclusions : These results suggest that Yonnyuniksoogobon-dan promotes hair growth and this effect is related to up-regulation of EGF and VEFG expression and down-regulation of TGF-${\beta}$1 and iNOS expression on hair roots.

  • Low-power laser(LPL) delivers a small amount of energy without elevation of tissue temperature. LPL has been reported to have biostimulation effects including anti-inflammatory, analgesic, regenerative, immunocorrective, and vasodilative effects. However, the effect of LPL on hair growth has rarely been studied. We investigated the effect of LPL on hair growth in the mouse. After depilation of back skin of mice, we classified the mice into 4 groups: control, laser irradiated group, $MoandMore^{(R)}$ applied group, and Spella $707^{(R)}$ applied group. Laser irradiation or application of these drugs were performed on the back skin of the mice for 30 days. The results are summarized as follows. Hair growth of control was first observed at 13 days after depilation, and complete hair regrowth was observed at 25 days. Hair growth of both laser irradiation group and $MoandMore^{(R)}$ applied group was first observed at 9 days after depilation, and complete hair regrowth was observed at 20 days. Hair growth of Spella $707^{(R)}$ applied group was firstly observed at the 9 days after depilation, and complete hair regrowth was observed at the 15 days. Hair growth started at the irradiation site in the laser irradiation group, but it started at the random sites in other groups. In conclusion LPL irradiation have a stimulating effect on the hair growth in the mouse.

  • NDM hair tonic is composed of several plant extracts which are known to be used in oriental medicine. This study was carried out to investigate the effect of NDM hair tonic on hair regrowth in an alopecia model of C57BL6 mice. Hair of six-weeks old mice were trimmed by electric clippers and electric shavers, so as not to damage the skin. The next day, mice without visible scraches were selected, randomized and separated in groups of 6 mice. There were four experimental groups including saline (negative control), 50% ethanol (vehicle control), 3% minoxidil (MXD), and NDM tonic. The test compounds were topically treated with 0.15 $m\ell$ per mouse per day for 2 weeks. The hair regrowth was determined photographically and histologically and the quantity of endocrine factors, IGF-1 and TGF-$\beta$, in the skin of mice was measured by PCR. No clinical signs were found in all animals. The topical treatment of NDM tonic for 2 weeks to dorsal skin accelerated hair regrowth faster than either the controls or MXD treatment. The NDM tonic treatment also promoted hair follicle development and elongation as compared with the controls or MXD treatment. Both NDM tonic and MXD treatment significantly increased the expression of IGF-1 and TGF-$\beta$ in the skin of C57BL6 mice as compared with the controls (p<0.05). These results suggest that NDM tonic has a hair growth activity and be useful for the treatment of baldness or alopecia.

  • Objective: Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) is one of the representative prescriptions for invigoration of vitality and nourishing of the blood. This study was carried out to investigate the effects of Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) on hair regrowth and cytokine changes in a shaving model of C57BL6 mice. Method: Five-week-old mice were acclimated for 1 week at a temperature between $21-23^{\circ}C{\acute{E}}$, 40-60% relative humidity, and 12h of a light/dark cycle before beginning of the experiment. There were two groups including normal saline (control) and a positive control of oral intake of Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) extract (sample) in 18 female mice. The test compounds were topically treated once a day over 14 days. The hair regrowth was photographically and histologically determined during the experimental period of 14 days. Revelation of TGF-${\beta}1$ and EGF were also determined using immunohistochemistry. In addition to that, IFN-$\gamma$, IL-4 and IL-10 were determined in serum. Results: Hair regrowth in the sample group was promoted earlier and faster than the control group, as shown by concentrations of hairs and thick-hair ratio in the sample group. TGF-${\beta}1$ was not revealed in either control or sample group. EGF was strongly positive in out root sheath of some thick hair of the sample group. Serum IFN-$\gamma$ was significantly decreased in the sample group compared with the control group at 7 experimental days. However, it was not significantly decreased at 14 experimental days. Serum IL-4 was significantly increased in the sample group compared with the control group at 7 experimental days. However, it was not significantly decreased at 14 experimental days. Serum IL-10 was decreased in the sample group compared with the control group, but with no real statistical significance. Conclusion: These results suggest that Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) has hair growth promoting activity and it can be used for treatment of alopecia. Also, these effects relate to EGF revelation of hair roots, a decrease in serum IFN-$\gamma$, and an increase of serum IL-4.
