Yak-ju treatment is regarded as a new way to give a medication, and used many parts of medical field such as musculo-skeletal, aesthetic and cosmetic part. Recently I've experienced a good result by Yak-ju treatment for managing obese patient who had failed to lose his weight by conventional existing treatments comprised of herbal medicine, electro-lypolysis, negative pressure, ear acupuncture, behavior modification therapy and education for diet and exercise. This method can be recommended as a new method for curing obesity that can make up for the weak point of existing ways.

Palmitoyl CoA was found to inhibit corn embryo axis glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase, which were also inhibites by polyamines. However, reversal of inhibition of both enzymes by palmitoyl CoA was made by spermine. Activity of corn embryo axis protein kinase was found to increase steadily after germination. Activation and inhibition of protein kinase were made by MgCl$_2$and all polymines, respectively. Suc results suggest that fatty acid biosynthesis and lypolysis could be regulated to some extent by polyamines in corn embryo axis.

Soy and soy foods are a rich source of isoflavones, which possess several biological activities. The effect of soy isoflavones, genistin and diadzin and their respective aglycones, on glucose uptake in adipocytes isolated from normal or high-fat fed rats was examined. As expected, insulin stimulated glucose uptake in a concentration-dependent manner. However, genistin and daidzin and their aglycones inhibited glucose uptake in a concentration-dependent (25-100μM) manner. In a time-course response, the aglycones significantly inhibited glucose uptake throughout 3 hr (after 30, 60, 120, 180 min), whereas the glycones only significantly inhibited the glucose uptake after 120 min and 180 min in the isolated rat adipocytes. Thus, the glucosides of genistein and daidzein, i.e. genistin and daidzin, were much less effective in inhibiting glucose uptake than their aglycones. In addition, genistin and daidzin did not significantly affect the insulin-stimulated glucose uptake, whereas genistein and daidzein did significantly inhibited glucose uptake compared to the vehicle control group by 47.5% and 24.8%, respectively (p < 0.05). The isoflavones also significantly inhibited glucose uptake in adipocytes isolated from rats fed a high-fat diet (50% of total calorie intake) when compared to the vehicle control. Finally, the isoflavones were found to enhance lipolysis in adipocytes isolated from high-fat fed rats, where the glycerol released by the aglycones was also higher than that released by the glycones. The current results showed that the inhibitory effect of daidzein on glucose uptake was very similar to that of genistein. The aglycones were more potent in inhibiting the uptake of glucose and a more potent stimulator of lypolysis than the glycones in adipocytes isolated from high-fat fed rats.

In this study, Albizziae Cortex extracts (ACE) have potent effects on adipogenesis and on lipolysis in OP9 cells. There was no cytotoxicity while cells were treated with ACE in designated time intervals, unaffected by various concentrations. In the cells with ACE-treated, increases in fat storage were inhibited, and also confirmed by Oil red O. To understand the underlying mechanism at the molecular level, the effects of ACE were examined on the expression of the genes involved in adipogenesis by using real-time PCR. In this cell model, the mRNA level of adipogenic genes such as peroxisome-proliferator-activated receptors gamma ($PPAR{\gamma}$) and CAAAT/enhancer binding protein alpha ($C/EBP{\alpha}$) were decreased by ACE treatment, comparing with those of control group. Collectively, our data suggest that ACE may have great potential as a novel anti-obesity agent.

In previous studies, we confirmed that the ethanol extract of Polygonatum sibiricum (ID1216) has anti-obesity effects on high-fat diet-fed mice. To identify the obesity-related genes affected by ID1216, we studied its effects both in vivo and in vitro. In mice, single administration of ID1216 increased the expression of obesity-related genes including sirtuin1 (SIRT1), peroxisome proliferator-activated receptor ${\gamma}$ coactivator $1{\alpha}$ ($PGC1{\alpha}$) and peroxisome proliferator-activated receptor ${\alpha}$ ($PPAR{\alpha}$) compared to that in mice administered the vehicle; their downstream genes (uncoupling proteins, acyl-CoA oxidase, adipocyte protein 2, and hormone-sensitive lipase) were also increased by ID1216. In fully differentiated 3T3-L1 adipocytes, ID1216 showed the same effects on anti-obesity genes as those in the animal model. Based on these results, we propose that ID1216 has anti-obesity effects by regulating the $SIRT1-PGC1{\alpha}-PPAR{\alpha}$ pathway and their downstream genes, thereby controlling energy and lipid metabolisms.

Leek(Allium tuberosum Rotter) is a korean traditional herb of which leaves are used for daily food. In order to improve the potency of leek as a functional food, we investigated the several biochemical functions in vitro. The quinone reductase activity, an anticarcinogenic enzyme, was induced 2 times at the concentration of 1mg/ml of leek as compared to that of negative control(80% methanol). The induction of SOD(Superoxide dismutase) activity was also demonstrated. But the functional activities of leek were shown to be a little difference depending on the place where the leek was produced. The difference might to be due to the different environmental factors where affects the growth of leek. In an experiment to test the lypolytic activity of leek, the glycerol release was significantly increased(about 3 times to that of negative control). This was suggested that leek can be considered as a potential food for diet. The above results provide the potential food, and more profound research is requested.

Bee (Apis mellifera L.) venom is used for the treatment of various human diseases due to its known anti-inflammatory and antibacterial properties. This study investigated the effect of purified bee venom (PBV) on adipogenesis in 3T3-L1 preadipocytes. There was no cytotoxicity while cells were treated with PBV by various concentrations. In the PBV treated cells increases in fat storage were inhibited and also confirmed by oil red o staining. To understand the underlying mechanism at the molecular level were examined on the expression of the genes involved in adipogenesis by using real-time PCR. In this cell model, the mRNA level of adipogenic genes such as peroxisome-proliferator-activated receptors gamma (PPARγ) and CAAAT/enhancer binding protein alpha(C/EBPα) were decreased by PAE treatment, comparing with those of control group. Theses results suggest that PBV inhibits adipocyte differentiation in 3T3-L1 cells and can be used as an efficient natural substance to manage anti-obesity.
