This experiment was investigated the effects of fresh and ginger processed Pinelliae Rhizoma extracts on hair growth activity, and its fractions(chloroform, ethyl acetate and water fractions) obtained from fresh Pinelliae Rhizoma on hair growth activity of the normal and spontaneous alopecia areata model of C57BL/6N mice for 16 days. The results were as follows: In fresh Pinelliae Rhizoma extracts treated group, hair growth effect was observed in whole skin area(100%) all the normal mice in whose hair had been clipped on 16th days. In ginger processed Pinelliae Rhizoma extracts treated group, hair growth effect was observed in whole skin area in 25% of normal mice in whose hair had been clipped on 16th days. But in control group, hair growth effect was observed in a part of whole skin area in 25% of normal mice. In fresh Pinelliae Rhizoma extracts treated group, hair follicles of middle stage of anagen phase was observed and it were grown down to subcutaneous tissue of skin in all the mice on 10th day. But in ginger processed Pinelliae Rhizoma extracts treated group and control group, Most of hair follicles of telogen phase was observed in skin. The treatment of extracts of fresh Pinelliae Rhizoma increased the expression of TGF-$\beta$(146%), IGF(107%), and prolactin(115%) in the skin of normal C57BL/6N mice compared to control group(100%). But expression of placenta lactogen(93%) was decreased in the skin of normal C57BL/6N mice compared to control group(100%). In spontaneous alopecia model, The hair growth activity of fresh Pinelliae Rhizoma extracts treated group(100%) was observed to be strong compared with the control group(20%) on 15th day. Hair growth activity on chloroform fractions of fresh Pinelliae Rhizoma extracts was observed in whole skin area in 75% of normal mice on the 9th day. In water and ethyl acetate fractions, hair growth activity was observed in a part of whole skin in 75% and 25% of normal mice, respectively. but hair growth activity of control group was not observed. After application of fractions of fresh Pinelliae Rhizoma extracts for 10 days, hair follicles of chloroform fraction treated group was observed middle stage of anagen phase and hair follicle were grown down to subcutaneous tissue of skin in all the mice. But hair follicles of initial stage of anagen phase were observed in water and ethyl acetate fractions. Most of hair follicles of telogen phase was observed in skin of control group. These experiments suggest that extracts of fresh Pinelliae Rhizoma may stimulate the topical hair growth activity and its chloroform fractions can be useful for treatment of alopecia areata.
