The effect of Spirodelae Herba Pharmacopuncture on Adipocyte Metabolism
Abstract
Objectives : The purpose of this study is to investigate the effects of Spirodelae Herba pharmacopuncture(SHP) on the adipogenesis in 3T3 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 preadipocytes were differentiated with adipogenic reagents by incubating for 3 days in the absence or presence of SHP ranging from 0.01 to 1.0㎎/㎖. The effect of SHP on adipogenesis was examined by measuring glycerol-3-phosphate ehydrogenase(GPDH) activity and by Oil Red O staining. Mature adipocytes from rat epididymal fat pad was incubated with SHP ranging from 0.01 to 1.0㎎/㎖ for 3 days. The effect of SHP on lipolysis was examined by measuring free glycerol released. Fat tissue from porcine skin was injected with SHP ranging from 0.1 to 10.0㎎/㎖ to examine the effect of SHP onhistological changes under light microscopy. Results : Following results were obtained from the preadipocyte proliferation and lipolysis adipocyte and histologic investigation of fat tissue 1. SHP showed the effect of decreased preadipocyte proliferation on the high dosage(1㎎/㎖). 2. SHP showed the effect of decreased the activity of glycerol-3-phosphate dehydrogenase (GPDH) on the high dosage(1㎎/㎖). 3. Investigated the changes in lipolysis of differentiated adipocyte after treated SHP, we knew that these pharmacopunct -ure showed increasing the effect of lipolysis in all concentration significantly. 4. Investigated the histological changes in porcine fat tissue after treated SHP, we knew that these pharmacopuncture showed significant activity to the lysis of extensive cell membranes on high dosage(10.0㎎/㎖). Conclusions : These results suggest that SHP efficiently induces diminishing proliferation of preadipocyte and lipolysis in adipose tissue.
