Antimicrobial activities of three different extracts from experimentally prepared scute decoction, commercial scute decoction and an extract from Scutellaria baicalensis were evaluated and their inhibitory potencies were compared. Both the extracts from scute decoction and Scutellaria showed rather strong antimicrobial activities against E. coli and St. aureus at the low concentration of 2.5 mg/ml. On the other hand, the extract of commercial scute decoction was found to show an inhibitory effect at higher concentration (75 mg/ml). All preparations did not inhibit the fungal growth of Aspergillus niger. Both Sh. dysenteriae (Subgroup A) and Sh. boydii (Subgroup C) which were used for determination of the strain differences in Shigelia spp. had almost the same susceptibility to the extract from sucute decoction.

Galgeun-tang (GGT) is a traditional herbal medicine generally used to treat cold, fever, headache, migraine and convulsion. To investigate the difference of ingredient and efficacy of GGT according to production method, mix extract powder and decoction, the quantities of index components, antioxidant and anti-inflammatory effects of two kinds of GGT formulation were compared. The contents of ten index components were simultaneously analyzed with HPLC. A HPLC method was developed and validated for the simultaneous determination. The GGT mix extract powder contained higher puerarin and daidzin content than the decoction, while the GGT decoction contained higher cinnamic acid and glycyrrhizic acid content than the mix extract powder. But ingredient of GGT mix extract powder and decoction was statistically very similar (r=0.8335). GGT decoction showed higher antioxidant effect than GGT mix extract powder, but the difference was low. The patterns of productions for NO, iNOS, COX-2, TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 were decreased along the increasing dose of GGT formulation in LPS-induced RAW 264.7 macrophages. The inhibitory effects on NO, iNOS, COX-2, IL-$1{\beta}$ and IL-6 in Raw 264.7 cell were very similar to each other. The results obtained in this study could be used as fundamental data for verifying the equivalence and effectiveness of the herbal medicines.

This study was purposed to research the anti-cancer effects of Bistortae Rhizoma. A total extract of Bistortae Rhizoma decoction was prepared. By measuring the cell proliferation, apoptosis, morphology and cytokine level from the extracts, the influence on HepG2 cell, SNU-1 cell and A549 cell was compared. The Bistortae Rhizoma decoction extract did not control HepG2 cell proliferation but controlled SNU-1 cell and A549 cell proliferation. In particular, the inhibitory effect on SNU-1 cell proliferation was highest. The Bistortae Rhizoma decoction extract showed to increase the apoptosis of the HepG2 ceil, SNU-1 cell and A549 cell in a dose-dependent manner. In particular, the promotion effect of the apoptosis was highest in SNU-1 cell. Among the various fraction extracts of the Bistortae Rhizoma decoction, n-BuOH extraction showed the greatest increase of the apoptosis of the HepG2 cell. The Bistortae Rhizoma decoction extract decreased dose-dependently the secretion of the TGF-$\beta$ in the HepG2 cell, SNU-1 cell and A549 cell and increased the secretion of the TNF-$\alpha$ and the IFN-$\gamma$. These results suggest that the total extract of Bistortae Rhizoma decoction has anti-cancer effect against SNU-1 cell and A549 cell.

Objectives : Atopic dermatitis is a chronic inflammatory skin disease characterized by pruritic and erythematous skin lesions. The purpose of this study was to investigate the suppressive effects of Lonicerae Flos, Forsythiae Fluctus and Hwangryunhaedok Decoction Pharmacopuncture on the development of atopic dermatitis-like skin lesions in NC/Nga Mice. Methods : The Atopic Dermatitis was induced by biostir AD on the mice's back skin. Experimental groups were divided into three including LFP(Lonicerae Flos Pharmacopuncture, EtOH extract), FFP(Forsythiae Fluctus Pharmacopuncture, EtOH extract) and HHP(Hwangryunhaedok Decoction Pharmacopuncture, Hydrodistillation extract). Every second day, the mice of three groups were treated with $0.1m{\ell}$ of pharmacopuncture using a syringe at right and left acupoints ($BL_{13}$), alternatively. On the control group, normal saline was used instead of pharmacopuncture. Subsequently optical observation with a handscope, a clinical skin score, Tissue(general/immune) mast cell, Serum IgE level, Serum histamine level, and Serum lymphokine(IL-2, IL-4, $IFN-{\gamma}{\gamma}$) were measured. Results : FFP and HHP decreased the clinical skin score, the total cell number of mast cells, and the Serum total IgE level and Serum histamine level. In Serum lymphokine levels, all groups were decreased to the IL-4 level, LFP and FFP were increased to the IL-2 level, and LFP was increased to the $IFN-{\gamma}$ level. Conclusions : From the above results, Forsythiae Fluctus Pharmacopuncture (EtOH extract) and Hwangryunhaedok Decoction Pharmacopuncture (Hydrodistillation extract) exerted anti-allergic and anti-inflammatory effects, suggesting a promising agent for improving atopic dermatitis related symptoms.

Two kinds of ginseng extracts were prepared and their brown color and radical scavenging activity were evaluated. The extract prepared by decoction after steaming exhibited deeper brown color and stronger radical scavenging activity than the extract prepared by decoction only. The difference in color and radical scavenging activity was greater in white ginseng than in fresh ginseng. Steaming white ginseng for 3 h was equivalent to 45 h of decoction in its brown color and radical scavenging activity. Consequently, we believe steaming process is better method than decoction to increase the biological activity of ginseng.
