Traditional medicines usually use combinational formula that are prepared by mixing different varieties of medicinal herbs and boiling them in water to yield a decoction. In recent years a modified method has been proposed and practiced wherein the individual herbs are boiled with water separately and later these extracts are mixed together for use. We attempted to evaluate their equivalence in terms of its polyphenol contents and DPPH radical scavenging activity. The polyphenol contents as well as the DPPH radical scavenging activities were very similar to each other.

Traditional medicines usually use combinational formula that is prepared by mixing different varieties of medicinal herbs and boiling them in water to yield a decoction. In recent years a modified method has been proposed and practiced wherein the individual herbs are boiled with water separately and later these extracts are mixed together for use. This practice has lead to a constant controversy concerning the chemical and biological equivalence between the preparations arriving out of these two methodologies. In this research, we attempted to study the effects of traditional and individual preparation of Ssanghwa-tang (ST) to evaluate their equivalence in terms of its antioxidant activity and polyphenol content. The study results indicate that the polyphenol contents as well as the extraction yields of these two preparations were very similar to each other.

The present study was aimed to investigate proteome affected by Panax ginseng extracts in chicken muscles. The whole muscle proteins from chicken fed boiled extracts of 0% (control), 1%, 3%, and 5% Panax ginseng in water were separated by two-dimensional electrophoresis (2-DE) gels using immobilized non-linear gradient (pH 3-10) strips. More than 300 protein spots were detected on silver staining gels. Among them, four protein spots were distinctively up-regulated by Panax ginseng treatments and further investigated by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). The obtained MS data were searched against SwissProt database using the Mascot search engine. The up-regulated proteins were finally identified as $\alpha$-tropomyosin (2 spots), triosephosphate isomerase, and one unknown protein. Based on the known functions of the identified proteins, they are highly related to muscle development and enhanced immunity in chickens. These proteins can give valuable information of biochemical roles for Panax ginseng in chicken meats.

Inhibition of inflammatory response, acceleration of basal cell growth, and balanced synthesis of extracellular matrix (ECM) are important in healing of cutaneous open wounds. In order to evaluate the healing effects of water extracts of Radix Astragali (the root of Astragalus membranaceus (Fisch.)) on open wound at early stage, the experimental open wounds were generated on the dorsal sides of SD rats under anesthesia. The boiled-water extracts of Radix Astragali $(100{\mu}l)$, soaked into an occlusive film dressing were applied once a day for eleven consecutive days. The healing process was assessed by measuring macroscopic appearance and wound areas of the open wounds. The molecular aspects of healing process by Radix Astragali extracts were also investigated by Hematoxylin-Eosin (H-E) double staining and immunohistological staining of collagen type I in the healed skin area, implying cell density and linear alignment of the granulation tissue, and ECM synthesis and its remodeling, respectively. The Astragali radix extracts were found to significantly accelerate the cutaneous wound healing by suppressing the inflammation and stimulating the basal cell growth in wounded area, as compared to epidermal growth factor (EGF).

사용 소금에 따른 된장의 암세포 성장 억제효과를 조사하기 위하여 4종의 천일염(1년 숙성 천일염, 4년 숙성 천일염, 토판염, 육염)을 사용하여 된장을 제조하였다. 대조구로는 정제염을 사용한 된장을 제조하여 실험을 수행하였다. 된장의 모든 제조 조건(원료, 제조방법, 발효 미생물, 발효조건 등)을 동일하게 하여주고 소금의 종류만을 달리하여 발효된 된장이 인체 위암세포(AGS)와 대장암세포(HT-29)의 성장 억제효과와 인간 정상세포(BJ)에 미치는 세포 독성을 조사하였다. 숙성된 된장을 물과 메탄올을 이용해 추출하여 사용 소금에 따른 된장의 암세포 성장억제효과를 MTT assay를 사용해 살펴보았다. 소금의 종류를 달리한 된장의 물 추출물과 메탄올 추출물은 AGS 위암세포, HT-29 결장암세포 대해서 모두 농도 의존적으로 높은 세포생육 억제율을 나타내었다. AGS의 경우 4년 숙성 천일염 된장의 물 추출물과 메탄올 추출물이 최대 처리 농도인 1.000 mg/mL에서 53%, 55%의 억제율을 나타내어 다른 종류의 소금에 비해 암세포 생육 억제효과가 매우 뛰어남을 확인하였다. 이어서 토판염, 육염, 1년 숙성 천일염, 정제염순으로 암세포 생육 저해 효과를 나타내는 것으로 관찰되었다. HT-29의 경우 AGS에 대한 암세포 성장 억제효과보다는 다소 낮지만 물 추출물의 최대 처리 농도 시 4년 숙성 천일염이 44%의 억제율을 보여 가장 높았으며 나머지 4종의 소금으로 제조한 된장들은 30~40% 정도의 억제 효과가 관찰되었다. 또한 메탄올 추출물에서도 위와 비슷한 경향을 보임을 확인하였으며 소금의 종류를 달리한 된장의 물 추출물과 메탄올 추출물은 모두 정상세포 BJ에 대해 세포독성을 거의 나타내지 않았으며 오히려 세포 성장효과를 보였다. 모든 추출물에서 우수한 암세포 생육 억제현상을 나타낸 4년 숙성 천일염 된장의 메탄올 추출물을 AGS, HT-29, BJ 세포에 처리하였을 때, 정상세포 BJ에 대해서는 처리 전후로 큰 차이가 관찰되지는 않았으나 세포 밀도의 감소와 함께 일부 세포 수축 현상을 관찰할 수 있었다. 따라서 이러한 결과들은 천일염 된장이 암세포 생육억제에 좋으며 그 중에서도 4년 숙성 천일염 된장이 가장 뛰어난 항암효과를 지님을 시사하고 있다.

Bioactivity of the extract from various processed garlic was evaluated based on the inhibition of lipoxygenase(LPO), and the effect of some stabilizers on the bioactivity was investigated. Water, ethanol or chloroform extract of 30 min boiled garlic showed 75%, 76% or 70% inhibition, respectively, compared to extracts of fresh garlic. In pickled garlic, LPO inhibition decreased gradually during storage. Chloroform extract of 40 day-stored pickled garlic inhibited LPO by 77%, and even on 60th day storage it still retained inhibitory effect of 73%, compared to that of fresh garlic. Meanwhile, the powdered (freeze-dried) garlic showed more bioactivity(80%) than the other processed garlics, and moreover, the jrreversible/unstable components seem to be stabilized by freeze-drying. The optimum pH for stabilization of bioactive components in garlic macerate was pH 3 for 48 hr incubation and pH 11 for 6 hr incubation. In addition, the effect of NaCl was not so great, although but maximal stabilization was observed at 150 mM. Stabilizing effect of $\alpha$-tocopherol was markedly great, and at 6mM it showed 308% stabilizing effect after 48hr incubation. More stabilizing effect was observed at lower concentrations of ascorbic acid($\leq$0.6mM) than higher concentrations. The stabilizing effect of soybean oil was found to be remarkable only during initial period(6 hr) of incubation.

Precipitation reaction occured between berberine in Coptidis Rhizoma and glycyrrhizin in Glycyrrhizae Radix when they were boiled together in aqueous solution and the supernatant solution thus obtained did not show any antibacterial activity which was derived from berberine. The content of berberine in BG and CGP by HPLC analysis were 41.1%, 8.3% respectively. BG was occured mostly at pH 5.0. The solubility of berberine was 0.15%, while that of BG and CGP was 0.07%, 0.12%, respectively. CGP shown more increased antibacterial activity to gram positive bacteria, S. dysenteriae and K. pneumoniae than berberine. The absorption rates of CGP in stomach, duodenum and jejunum of rats were compared with those of Coptidis Rhizoma water extracts (CR), which were increased more than CR. The time required for the maximum serum concentration of berberine from CGP in mice was 90 minutes after oral administration. The maximum serum concentration of berberine from CGP was higher than that from CR. The dissolution of CGP was increased more than berberine and BG in both artificial gastric and intestinal fluids. The dissolution of CGP pill made from gelatin was 63.4% in artificial gastric fluids and that made from CMC was 76.0% in artificial intestinal fluids.
