Objective : UV irradiatiion causes skin-aging involving coarse wrinkles, thickning, dyspigmentation, and rough skin surface. This study was aimed to elucidate the anti-winkle activity of complex diet of Korean red ginseng (RG) and fish oil (FO) on UV-induced Photoaging. Methods : To investigated photo-protective effects of Korean red ginseng and fish oil on UV-induced damaged skins, SKH hairless female mice were randomly divided into six groups [control, UV, UV/RG, UV/FO, UV/RG/FO(low), UV/RG/FO(high)]and orally administered three times a week respectively. UV radiation was applied to the backs of the mice three times a week for 8 weeks. Expressions of matrix metalloproteinase (MMP)-3, MMP-13 and tissue inhibitor matrix metalloproteinase (TIMP)-1 in skin were measured by immunohistochemical staining. Results : In this study, UVB-induced epidermal hypertropy was diminished by RG group or FO group or complex group of RG and FO. Expression levels of MMP-3 and MMP-13 were reduced and expression level of TIMP-1 was increased by RG group or FO group or complex group of RG and FO. Especially MMP-3 and MMP-13 were markedly reduced by diet of FO and complex diet of RG and FO compared with untreated group. Conclusions : This results suggest that complex diet of RG and FO have a anti-wrinkle activity on UV-induced photo-aging and intrinsic aging.

Anti-hyperlipidemic effect of red ginseng (RG; the steamed root of Panax ginseng C.A. Meyer) and Crataegii fructus (CF, the fruit of Crataegus pinnatifida BGE), which are used frequently in China and Korea as herbal medicines to treat arteriosclerosis, were investigated. Treatments of RG and CF significantly reduced blood triglyceride (TG) and total cholesterol (TC) levels in Triton WR-1339-induced hyperlipidemic mice and serum TG levels in corn oil-induced hypertriglyceridemic mice. Ginsenoside Rg3 and ursolic acid, the main constituents of RG and CF, respectively, also reduced TG and TC levels in hyperlipidemic mice. RG and CF significantly lowered the high blood TG and TC levels and body and epididymal mass weights induced by long-term feeding of a high-fat diet and increased the high-fat diet-induced decrease in blood HDL cholesterol levels. RG and Rg3 reduced the blood TC levels more than CF and ursolic acid. However, blood TG level were reduced by CF and ursolic acid more than RG and Rg3. RG, CF, and their constituents also inhibited pancreatic lipase and HMG-CoA reductase activities. The most potent inhibitor was Rg3. These findings suggest that RG and CF may be suitable for the therapies of hypercholesterolemia and triglyceridemia, respectively.

Background: Despite the large number of studies on ginseng, pharmacological activities of ginseng seed oil (GSO) have not been established. GSO is rich in unsaturated fatty acids, mostly oleic and linoleic acids. Unsaturated fatty acids are known to exert a therapeutic effect in nonalcoholic fatty liver disease (NAFLD). In this study, we investigated the protective effect and underlying mechanisms of GSO against NAFLD using in vitro and in vivo models. Methods: In vitro lipid accumulation was induced by free fatty acid mixture in HepG2 cells and by 3 wk of high fat diet (HFD)-feeding in Sprague-Dawley rats prior to hepatocyte isolation. The effects of GSO against diet-induced hepatic steatosis were further examined in C57BL/6J mice fed a HFD for 12 wk. Results: Oil Red O staining and intracellular triglyceride levels showed marked accumulation of lipid droplets in both HepG2 cells and rat hepatocytes, and these were attenuated by GSO treatment. In HFD-fed mice, GSO improved HFD-induced dyslipidemia and hepatic insulin resistance. Increased hepatic lipid contents were observed in HFD-fed mice and it was lowered in GSO (500 mg/kg)-treated mice by 26.4% which was evident in histological analysis. Pathway analysis of hepatic global gene expression indicated that GSO increased the expression of genes associated with ${\beta}$-oxidation (Ppara, Ppargc1a, Sirt1, and Cpt1a) and decreased the expression of lipogenic genes (Srebf1 and Mlxipl), and these were confirmed with reverse transcription and quantitative polymerase-chain reaction. Conclusion: These findings suggest that GSO has a beneficial effect on NAFLD through the suppression of lipogenesis and stimulation of fatty acid degradation pathway.

알코올에 의한 지방간(지방변성증)은 에탄올 대사에 의해 감소되는 당량의 과도한 발생에 의해 유발된다. 일반적으로 만성적인 에탄올 투여는 간 지질의 합성을 증가시키는 sterol regulatory element-binding protein 1c (SREBP-1c)를 조절함으로써 지방변성증을 유발시킨다. SPEBP-1c에서 에탄올의 영향은 간에서의 지방대사를 조절하는 NAD⁺ 의존적 단백질 탈아세틸화효소인 mammalian sirtuin-1 (SIRT-1)에 의해 조정된다. 홍삼은 항당뇨와 항비만 효과를 위해 아시아에서 광범위하게 사용되는 한약재이다. 홍삼의 약리학적 치료학적인 효과는 진세노사이드와 같은 생물활성 성분에 의해 주로 일어난다. 따라서 우리는 마우스 간세포주인 AML-12 세포에서 SREBP-1과 SIRT-1에대한 한국홍삼 추출물의 조절효과를 평가하였다. 알코올과 홍삼추출물(0-1,000 μg/ml)을 AML-12 세포주에 처리하고, 지방소립을 Oil red O 염색법으로 확인하고, western blots을 사용해 SIRT-1과 SREBP-1의 발현을 확인하였다. 에탄올을 처리한 세포에서 홍삼추출물은 SIRT-1과 SREBP-1c의 발현을 회복시켰다. 또한 에탄올이 처리된 세포에서 홍삼추출물과 진세노사이드 Rb₂와 Rd가 SREBP-1을 유의적으로 감소시키는 것으로 확인 되었다. 결과적으로 홍삼과 활성 진세노사이드 성분인 Rb₂와 Rd가 SIRT-1과 간 지질대사를 변화시키는 SREBP-1c의 아세틸화의 조절을 통해 알코올에 의한 간지방변성을 억제하는 것을 확인하였다.

Polycystic ovarian syndrome (PCOS) is a very common endocrine disorder in women of reproductive age. Nerve growth factor (NGF) may be involved in the pathogenesis of PCOS. In this study, we investigated the effect of Korean red ginseng extract (KRGE) on the ovarian morphology and NGF expression in an estradiol valerate (EV)-induced rat model. Polycystic ovaries were induced by a single intramuscular injection of estadiol valerate (4 mg, dissolved in sesame oil) in adult cycling rats. KRGE was administered orally (200 mg/kg body weight/day) for 60 consecutive days, beginning 60 days after the induction. Ovarian morphology was almost normalized and NGF was normalized in the EV+KRGE group. KRGE lowered the high numbers of antral follicles and increased the number of corpora lutea in the polycystic ovaries. The results are consistent with a beneficial effect of KRGE in the treatment of PCOS.

This study was carried out to select economical byproduct composts as the substitute for the traditional organic fertilizer, Yacto, in the cultivation of ginseng seedlings, and to investigate the application method of a selected compost. Among tested byproduct composts, popped rice hull compost was the best substitute for Yacto, while the application of domestic animal manure composts resulted in red skinned roots of ginseng seedlings. Optimal mixing ratio of the popped rice hull compost with virgin soil (fine sand) were 3~4 : 1 in bulk, showing the same root yield compared to that of conventional seedbed soil. When the popped rice hull compost was lower than $1\;{\pm}\;0.1%$ in nitrogen content, the expeller cake of oil seed was added to seedbed soil to rise nitrogen content until $1\;{\pm}\;0.1%$.

I assessed the B($a$)P content from the Ginseng extract, Red ginseng extract, and Ssangwha extract which have high viscosities. It wasn't easy to extract oil from these samples, consequently measuring of B($a$)P was difficult. In order to know the exact detecting contents, I injected standard material of B($a$)P to the above extractions and pre-treated for measurement but it was also difficult to measure of contents exactly. To improve of detecting method, I removed mucinous materials using a 85% phosphoric acid solution or 10% citric acid solution and then processed continuously with $60^{\circ}C$ hot water. The analysis revealed that extracting the samples contained B($a$)P determined the rate of each 70%, 55%, 67% could increase. As a result the detecting method of B($a$)P contents could be improved.

Background: Withania somnifera (Solanaceae), generally known as Indian ginseng, is a medicinal plant that is used in Ayurvedic practice for promoting health and longevity. This study aims to identify the bioactive metabolites from Indian ginseng and elucidate their structures. Methods: Withanolides were purified by chromatographic techniques, including HPLC coupled with LC/MS. Chemical structures of isolated withanolides were clarified by analyzing the spectroscopic data from 1D and 2D NMR, and HR-ESIMS experiment. Absolute configurations of the withanolides were established by the application of NMR chemical shifts and ECD calculations. Anti-adipogenic activities of isolates were evaluated using 3T3-L1 preadipocytes with Oil Red O staining and quantitative real-time PCR (qPCR). Results: Phytochemical examination of the roots of Indian ginseng afforded to the isolation of six withanolides (1-6), including three novel withanolides, withasilolides GeI (1-3). All the six compounds inhibited adipogenesis and suppressed the enlargement of lipid droplets, compared to those of the control. Additionally, the mRNA expression levels of Fabp4 and Adipsin, the adipocyte markers decreased noticeably following treatment with 25 µM of 1-6. The active compounds (1-6) also promoted lipid metabolism by upregulating the expression of the lipolytic genes HSL and ATGL and downregulating the expression of the lipogenic gene SREBP1. Conclusion: The results of our experimental studies suggest that the withasilolides identified herein have anti-adipogenic potential and can be considered for the development of therapeutic strategies against adipogenesis in obesity. Our study also provides a mechanistic rationale for using Indian ginseng as a potential therapeutic agent against obesity and related metabolic diseases.
