Objectives : This study was carried out to investigate the effects of Ephedrae Herba pharmacopuncture (EHP) on the adipogenesis in 3T3-L1 cells, lipolysis in rat epididymal adipocytes and histological changes in porcine adipose tissue. Methods : Inhibition of preadipocyte differentiation and/or stimulation of lipolysis play important roles in reducing obesity. 3T3-L1 preadipocytes were differentiated with adipogenic reagents by incubating for 3 days in the absence or presence of EHP ranging from 0.01 to 1.0 $mg/m{ell}$. The effect of EHP on adipogenesis was examined by measuring glycerol-3-phosphate dehydrogenase (GPDH) activity and by oil red O staining. Mature adipocytes from rat epididymal fat pad were incubated with EHP ranging from 0.01 to 1.0 $mg/m{ell}$ for 3 days. The effect of EHP on lipolysis was examined by measuring free glycerol released. Fat tissue from porcine skin was injected with EHP ranging from 0.1 to 10.0 $mg/m{ell}$ to examine the effect of EHP on histological changes under light microscopy. Results : The following results were obtained from present study on adipogenesis of preadipocytes, lipolysis of adipocytes and histological changes in fat tissue. Proliferation of preadipocytes was significantly inhibited by EHP at the concentration of 1.0 $mg/m{ell}$. Lipolysis of adipocytes was increased by EHP at the concentration of 0.1, 1.0 $mg/m{ell}$. Porcine fat tissues were widely injured by EHP at the concentration of 10.0 $mg/m{ell}$. Conclusions : From the above results, EHP efficiently induces inhibition of preadipocytes proliferation, lipolysis of adipocytes and histologic injury in fat tissues. Therefore, EHP may be useful to treat localized obesity.
