Abstract

Objectives : To investigate the effects of DL-HGF to hair growth activity in mouse, various kinds of ethosome and liposome formulations entrapped DL-HGF were produced and this study was carried out. Methods : The B16/BL6 mice were classified into five groups: vehicle control (Con) group, Et-1-applied group, Et-2-applied group, LP-1-applied group, LP-2-applied group. Active hair growth (anagen) was induced in the back skin by application of a waxosin mixture with subsequent depilation and the activity of hair growth was measured by macroscopic observation and histology. Results : In vehicle control group, there was no hair growth activity during experiment period. In Et-1-applied group, the rate of hair growth was about 100%, LP-1-applied group and Et-2-applied group showed 70-80% and 40-50% of hair growth rates, respectively. The rate of hair growth of LP-2-applied group was lower than other applied groups (20-30%). In H/E staining, Numerous hair folicles and hair shafts were observed in Et-1-applied group and other groups showed lower level of hair folicles and hair shafts formation than Et-1-applied group, Conclusion : Et-1 formulation showed highest hair growth activity than other ethosome and liposome formulations entrapped DL-HGF.
