Objectives : Acne, one of the most common disorders in dermatology clinic, is a chronic inflammatory disease which has the symptoms of comedones, papules, pustules, cysts, nodules and scars mainly on the face. Although some of pathologic findings are suggested, but the exact causes and mechanisms are not yet known in Western Medicine. Hwangryeonhaedok-Tang(HRHDT) is an antiinflammatory, antipyretic and detoxifying herb decoction. In this report, we would like to share our experience of acne treatment with HRHDT. Methods : We had treated several patients with acne, facial flushing and uprising febrile sensation on face using oral administration and external application of HRHDT. HRHDT is basically made up with Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex and Gardeniae Fructus. In this trial, several other herbs were added according to the individual patient's accompanying symptoms. After the decoction of herbs in amount for 10 days, $Yogourmet^{(R)}$ Kefir Starter 10 g was added to the herbal solution that was then fermented in an incubator at $25^{\circ}C$ for 72 hours, and divided into 30 doses. Results : Photographies were taken before and after the treatment. The severities of acne were evaluated with these photos according to the Korean Acne Grading System(KAGS). As results, we observed dramatic clinical improvements and the decreases of KAGS grades after the average treatment period of 8 weeks. The medication was orally administered 3 times a day and the external treatment was applied average twice a week during the whole treatment period. Conclusions : From these results, HRHDT may be considered as a good prescription for the febrile and toxic type of acne patients.

Pueraiae Radix (PR), Pueratia Folium (PF) and Sorbus commixta (SC) mixture, namely GS-SP (PR (1)/PF (2)/SC (0.5): v/v/v) was developed as hangover-relieving elixir and its effects on alcoholic metabolism have been investigated. The enzymatic activity of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) of GS-SP was shown higher than those of single treatment with PR, PL, SC, and the positive control group (YM-808). The survival rate of mouse liver cell line NCTC clone 1469 in the presence of acetaldehyde was 30.6, 22.2, and 8.7% at the GS-SP dosage level of 50, 100, and 200 μg/mL respectively. Different concentrations of 50, 100 and 200 mg/kg of GS-SP showed efficient activity for ADH and ALDH than YM-808 in rat fed with 25% ethanol. The levels of blood alcohol and acetaldehyde after oral administration of 200 mg/kg of GS-SP showed efficient activity of 11.7% and 37% than those of YM-808. These results have been supported to the potential for GS-SP to serve as an excellent potential in providing hangover relief and liver protection.

Numerous natural herbal compounds have been reported to inhibit adhesion and migration of leukocytes to the site of inflammation Licorice extracts, which have been widely used in traditional Chinese medicinal preparation, possess various pharmacological effects. Isoliquiritigenin, a biogenetic precursor of flavonoids with various pharmacological effects, is a natural pigment present in licorice. We attempted to explore whether licorice extracts and isoliquiritigenin mitigate monocyte adhesion to tumor necrosis factor-$\alpha$ (TNF-$\alpha$)-activated human umbilical vein endothelial cells (HUVEC). In addition, it was tested whether the inhibition of monocyte adhesion to the activated HUVEC accompanied a reduction in vascular cell adhesion molecule-l expression(VCAM-l). Dry-roasted licorice extracts in methylene chloride but not in ethanol markedly interfered with THP-l monocyte adhesion to INF-$\alpha$-activated endothelial cells. licochalcone A compound isolated from licorice extract in methylene chloride appeared to modestly inhibit the interaction of THP-l monocytes and activated endothelium. In addition, isoliquiritigenin abolished the monocyte adhesion with attenuating VCAM-l protein expression on HUVEC induced by INF-$\alpha$. These results demonstrated that non-polar components from dry-roasted licorice extracts containing licochalcone A as well as isoliquiritigenin were active in blocking monocyte adhesion to cytokine-activated endothelimn, which appeared to be mediated most likely through the inhibition of VCAM-l expression on HUVEC. Therefore, licorice may hamper initial inflammatory events on the vascular endothelium involving induction of endothelial cell adhesion molecules.

In this study, we evaluated the antiproliferative effects of Panax notoginseng, ginsenoside Rb1, and notoginsenoside R1 in the human breast carcinoma MCF-7 cell line. Our results indicated that both Panax notoginseng radix extract (NRE) and Panax notoginseng rhizoma extract (NRhE) possess significant antiproliferative activities in MCF-7 cells. Compared to control group (100%), at the concentrations of 0.05, 0.5, and 1.0 mg/ml NRE, cell growth was concentration-dependently reduced to 81.0 ${\pm}$ 6.1 (P < 0.01), 34.2 ${\pm}$ 4.8 (P < 0.001), and 19.3 ${\pm}$ 1.9 (P < 0.001), respectively. Similar results with NRhE at concentrations of 0.5 and 1.0 mg/ml were obtained in these MCF-7 cells. To identify the responsible chemical constituent, we tested the antiproliferation effects of two representative saponins, ginsenoside Rb1 and notoginsenoside R1, on the MCF-7 cells. The data showed that ginsenoside Rb1 was endowed with antiproliferative properties, while notoginsenoside R1 did not have an inhibitory effect in the concentrations tested. Our studies provided evidence that Panax notoginseng extracts and ginsenoside Rb1 may be beneficial, as adjuvants, in the treatment of human breast carcinoma.
