This study was designed to investigate the antihyperlipidemic activity of Fermented Rhus Verniciflua Stokes Extract(FRVSE) on diet-induced hyperlipidemia in rats. The animals were divided into 4 groups of the normal group(fed with normal diet), control group(fed with high fat diet), sample A group(fed with high fat diet and medicated FRVSE 192 ㎎/㎏/day), sample B group(fed with high fat diet and medicated FRVSE 384 ㎎/㎏/day), and received oral administration of each prescription with diet for a period of six weeks. The changes in the body weight, the liver weight, the epididymal fat weight, and the plasma levels of total cholesterol, triglyceride(TG), high density lipoprotein(HDL) cholesterol and low density lipoprotein(LDL) cholesterol were measured. In sample A group, the weight of liver and plasma level of TG decreased significantly. There was a significant decrease in the plasma level of total cholesterol, TG and LDL cholesterol in the sample B group. These results suggest that the FRVSE have a good antihyperlipidemic activity and a potential to treat hyperlipidemia.

Rhus verniciflua (RV) Stokes is a herbal medicine that helps improve blood circulation by stimulating digestion, removing extravasated blood, and raising body temperature. The purpose of this research was to study the anti-inflammatory effect of fermented soy products (FSP) containing a fermented RV (FRV) extract on lipopolysaccharides (LPS)-treatedd RAW 264.7 cells. Treatment with FRV extracts (1, 10, $100{\mu}g/mL$) downregulated nitric oxide (NO) and pro-inflammatory cytokines as compared to the LPS-treated group. Besides, the RV extract treatment suppressed the expression of genes related to pro-inflammatory cytokines, matrixins, inflammation, and apoptosis, while increasing the expression of genes involved in the antioxidant system. Furthermore, RVS extract upregulated antioxidant enzymes, such as glutathione, Cu,Zn-SOD, and catalase without changes in the Nrf2-Keap1 pathway. FSP (doenjang, ganjang) containing FRV extracts (0.1, 1, or $10{\mu}g/mL$) significantly decreased the NO and IL-6 levels in an FSP after 8 weeks of fermentation, but not the expression of genes involved in the inflammation and antioxidant system. These result indicate that an FRV extract and FSPs have a potential application in inflammatory conditions.

Fustin comprised >98 and 73.0-86.7% of the total flavonoid content in the bark, and the stems and lignum of Rhus verniciflua, respectively. The butein, fisetin, and sulfuretin content varied between 0.31-2.17, 0.27-3.32, and 0.15-0.80 mg/g on a dry weight basis, respectively, in different parts of Rhus verniciflua. The urushiol content was 5.09-6.29, 55.05-56.30, and 0.38-0.39 mg/100 g on a dry weight basis in the stems, bark, and lignum, respectively. This showed that the bark of the tree had the highest urushiol content. C15:3 (pentadecatrienyl catechol), C15:1 (pentadecenyl catechol), and C15:2 (pentadecadienyl catechol) comprised 63, 33-35, and 2-3% of urushiol congeners in the tree bark, respectively.

Purpose: In this study, skin and lotion containing 10% FRO were prepared to compare the skin improvement effects. Research design, data and methodology: After using cosmetics containing FRO ingredients, analysis was performed for 6 weeks. Results: As a result of measuring the moisture and elasticity of the pores, significant results were obtained only in the pores when used for 2 weeks between the experimental group and the control group (p<.001). Also after 4 weeks of use, moisture (p<.05) showed significant results, and after 6 weeks of use, moisture (p<.01) and elasticity (p<.001) showed significant.
