Objectives : Samhwangsasim-tang (SHSST) is a traditional Korean medication, which has been used in Korea for treatment of hypertension and chest pain. Hyperlipidemia and inflammation could influence hypertension and chest pain. This study investigated whether and how SHSST reduces the hyperlipidemia and inflammation related to high-cholesterol diet-induced obesity in rats. Methods : Mice were divided randomly into four groups: the normal diet group, high-cholesterol diet group, low dose treatment group supplemented with 30% ethanol extract of SHSST (L) and high dose treatment group supplemented with 80% ethanol extract of SHSST (H). L and H groups were orally administered with SHSST at the dose of 50mg/kg a day respectively and others were administered with the same volume of physiological saline. Results : Administration of SHSST resulted in a decrease in serum levels of total cholesterol and low-density lipoprotein. Expression of hepatic genes(SREBP2, LXR, LDLR, and HMG-CoA) related with cholesterol metabolism was also suppressed. In addition, SHSST decreased the expression of inflammation-related gene (TNF-${\alpha}$, IL-6, ICAM-1, VCAM-1, TGF-${\beta}1$ and fibronectin). Histological examinations also showed that the size of the adipocytes was smaller in the SHSST treated group than in the high-colesterol diet group. In an in vitro study, SHSST inhibited the production of nitric oxide in a concentration-dependent manner. Conclusions : This study indicates that SHSST has anti-hyperlipidemia and anti-inflammatory effects. It may also suggest that SHSST may be alternative therapy for treatment of hyperlipidemia and its complications.

Objectives : Atopic Dermatitis (AD) is chronic skin disease characterized by allergic hypersensitivity reactions. Samhwangsasim-tang Gamibang(SHSST) can treat skin disease by cooling down blood heat, clearing away congenital fever and detoxicating. This study was conducted to investigate the effects of SHSST on AD induced by oxazolone in mice. Methods : We investigated the effects of SHSST on skin tickness, skin lesions, erythema and melanin index, water content and histopathological changes in vivo. The effects on body weights and spleen body weight ratio were also investigated in mice with AD. Results : In our results, oral administration of SHSST ameliorated skin lesion such as flare, erythema, exudate and petechia and lowered skin thickness induced by oxazolone. In addition, SHSST lowered erythema index and elevated water content compared to AD control respectively. In the histopathological observation, oral administration of SHSST prevented epidermal hyperplasia and spongiotic changes which is a hallmark of skin inflammation respectively. Finally, SHSST did not affect spleen/body weight ratio. Conclusions : These data imply that SHSST can ameliorate skin lesion of AD such as flare, erythema, exudate and petechia, and be used to treat AD patients with relative safety.

Objectives : The aim of the present study is to investigate the hypotensive effect of Samhwangsasim-tang (SHSST), Samigangap-tang (SMGAT) and Bangtan-tang (BTT) in stroke-prone spontaneously hypertensive rats (SHR-SP). Methods : SHR-SP rats were treated with SHSST, SMGAT and BTT at dose of 200 mg/kg/day orally for 5 weeks, respectively. Results : Treatment SHR-SP rats with SMGAT significantly lowered blood pressure but not in the SHSST or BTT treat groups. On the other hand, SHSST, SMGAT and BTT ameliorated endothelium-dependent and independent vascular relaxation in the phenylephrine-precontracted aorta and carotid artery, respectively. Conclusions : These results indicated that SMGAT has an antihypertensive effect and SHSST, SMGAT and BTT improve vascular function in stroke-prone hypertensive rat model, respectively.
