We have studied the physico-chemical change and pharmacological transformation of traditional herbal medicines with processing. Evodia fruit (EF) has processed for the purpose of detoxification and reduction of its bitter taste. There are various methods of processing EF in Oriental medicinal reference. Among them, we processed EF according to the method of Sang-han theory, the most famous medicinal reference. We processed EF with washing in hot water, and then dried. Processed EFs(PEFs) were prepared according to the above procedure through repetition of 1,3,5 and 7 times respectively. The contents of weight loss, water extract, diluted ethanol extract, ether extract, total ash, acid insoluble ash, alkaloids and limonin in non-processed EF (NPEF) and PEFs were examined. The weight loss, and contents of water extract and dilute ethanol extract in PEF showed decrease in proportion to increase of washing time, while the contents of ether extract, total ash and acid insoluble ash showed little change as compared with those of NPEF. And the content of evodiamine and rutaecarpine was not changed distinctly. However, the content of limonin decreased in the final processed material in proportion to increase of washing times with hot water. And the intense of bitter taste in PEF was also reduced. These results were ascribed to the flowing-out of the water-soluble portion. The biological activities of NPEF and PEF were also investigated. In the test of DPPH scavenging effect, xanthine oxidase inhibition effect and TBA-Rs effect, PEF was more effective than NPEF in vitro. Also, both NPEF and PEF showed potent analgesic and anti-inflammatory effects against in mice. Especially, PEF by 3 times washing with hot water was more effective than other PEFs. From these results, it is considered that PEF should be prepared by 3 times washing with hot water.

As an effective non-pharmacological method of pain relief, hydrotherapy was widely used. And bath additive has been used for enhancing the efficacy of hydrotherapy, In the present study, as a bath additive, the analgesic activity of HAC, which composed of Corydalis turtschaninovii, Atractylodes japonica, and Harpagophytum procumbens(HAC), was investigated in the ventrolateral periaqueductal gray (VIPAG), lateral PAG (IPAG), central nuclei of amygdala (CeA), and the paraventricular nucleus of the hypothalamus (PVN) in mice, using writhing test and immunohistochemistry for c-Fos. Male C57BU6 mice weighing $25{\;}{\pm}{\;}2g$ (8 weeks of age) were used for this experiment. The animals were divided into five groups: the control group, the acetic acid treatment group, the acetic acid treatment and 0.01 g/L HAC-immersed group, the acetic acid treatment and 0.1 g/L HAC-immersed group, and the acetic acid treatment and 1.0 g/L HAC-immersed group. To induce somato-visceral pain in the experimental animals, a single intraperitoneal (i.p.) injection of acetic acid was administrated to each animal, and the animals of the control group received injections of equivalent doses of normal saline. The animals of the HAC-immersed groups were immersed the water with HAC powder at the respective doses deep enough to cover the mice body, and those of the control group and the acetic acid treatment group immersed the water without HAC powder at 10 min immediately after the acetic acid injection. Our present study has shown that the HAC reduced the acetic acid-induced abdominal constrictions and the acetic acid-Induced increase of numbers of c-Fos-positive cells in the VIPAG, IPAG, PVN, and CeA. The most potent analgesic effect appeared with the treatment of 1.0 g/L KB-immersed group. Based on our present results, it is very possible that HAC can be a potent therapeutic bath additive for alleviating pain without the fear of addiction to the drugs and side-effects associated with the prescription of multiple analgesic drugs.

Extracts of pine needles (Pinus densiflora Sieb. et Zucc.) have diverse physiological and pharmacological actions. In this study we show that pine needle extract alters pacemaker currents in interstitial cells of Cajal (ICC) by modulating ATP-sensitive $K^+$ channels and that this effect is mediated by prostaglandins. In whole cell patches at $30^{\circ}C$, ICC generated spontaneous pacemaker potentials in the current clamp mode (I = 0), and inward currents (pacemaker currents) in the voltage clamp mode at a holding potential of -70 mV. Pine needle extract hyperpolarized the membrane potential, and in voltage clamp mode decreased both the frequency and amplitude of the pacemaker currents, and increased the resting currents in the outward direction. It also inhibited the pacemaker currents in a dose-dependent manner. Because the effects of pine needle extract on pacemaker currents were the same as those of pinacidil (an ATP-sensitive $K^+$ channel opener) we tested the effect of glibenclamide (an ATP-sensitive $K^+$ channels blocker) on ICC exposed to pine needle extract. The effects of pine needle extract on pacemaker currents were blocked by glibenclamide. To see whether production of prostaglandins (PGs) is involved in the inhibitory effect of pine needle extract on pacemaker currents, we tested the effects of naproxen, a non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, and AH6809, a prostaglandin EP1 and EP2 receptor antagonist. Naproxen and AH6809 blocked the inhibitory effects of pine needle extract on ICC. These results indicate that pine needle extract inhibits the pacemaker currents of ICC by activating ATP-sensitive $K^+$ channels via the production of PGs.

본 연구에서, 비발효(ARE) 및 발효(ARE-F) 배초향 잎 열수 추출물의 피부 항산화 및 항염증 효능을 비교함으로써 프로바이오틱 발효의 효과를 검토하였다. ARE-F는 Lactobacillus rhamnosus HK-9 발효에 의하여 ARE로부터 제조되었다. In vitro 항염증 효능은 지질다당류(LPS)에 의하여 자극된 HaCaT 각질세포에서 일산화질소(NO), 활성산소종(ROS) 및 유도형 일산화질소합성효소(iNOS) 분석에 의하여 평가되었다. In vitro antiradical 활성은 2,2-diphenyl-2-picrylhydrazyl radical (DPPH) 소거 측정법에 의하여 평가되었다. LPS 자극에 의하여 증가된 NO, ROS 및 iNOS 수준에 미치는 ARE-F의 감소효과가 ARE에 의한 효과보다 현저히 강하였다. 그러나, ARE와 ARE-F의 DPPH 소거 효능에는 차이가 발견되지 않았다. ARE-F가 증강된 피부 항산화 및 항염증 효능을 갖고 있는데, 이 결과는 프로바이틱세균 발효가 배초향 잎의 일부 약리학적 효능을 증가시키는 효과적인 방법일 수 있음을 암시해 주고 있다. 요약하면, 배초향 잎 추출물의 피부항산화 및 항염증 활성이 프로바이오틱 세균인 L. rhamnosus HK-9에 의한 발효에 의하여 증강한다.

Cordycepin은 C. militaris의 주요 생리활성 물질로서 인체 면역기능 강화, 항염증, 항산화, 항노화 및 항암활성을 포함한 다양한 약리효능이 있는 것으로 알려져 있다. 본 연구에서는 HCT116 대장암세포를 이용하여 암전이의 주요 과정인 암세포의 이동성 및 침윤성에 미치는 cordycepin의 효능에 관하여 조사하였다. 본 연구의 결과에 의하면 세포독성이 없는 범위에서 cordycepin은 HCT116 세포의 이동성과 침윤성을 유의적으로 억제하였다. RT-PCR 및 Western blotting 결과에 의하면 cordycepin은 TJs의 주요 구성인자인 claudin family 인자들의 발현을 억제하였으며, 이는 TJ의 전기적 저항성의 증대와 연관이 있었다. Cordycepin은 또한 MMP-2 및 -9의 발현과 활성을 저해함과 동시에 TIMP-1 및 -2의 발현은 증가시켰다. 따라서 cordycepin에 의한 HCT116 대장암세포의 전이능 억제는 TJ의 견고성 증대와 MMPs의 활성 억제와 연관성이 있음을 알 수 있었다.

Xenopus oocytes를 이용하여 인삼의 유효 성분으로 알려진 Ginseng total saponin(GTS)의 신호 전달 기작을 two electrode voltage clamp 방법을 이용하여 연구하였다. GTS는 세포 바깥에 처리했을 때 -2OmV보다 더 positive한 voltage에서 커다란 outward current를 유도하였다. 그러나, 세포 안쪽에 GTS를 injection할 경우 아무런 효과가 없는 것으로 나타났다. GTS처리에 의한 outward current유발 효과는 GTS 투여 용량에 의존적인 것으로 나타났다(EC$_{50}$ : 4.4 $\mu\textrm{g}$/ml). GTS의 작용은 $Ca^{2+}$-activated Cl- channel blocker인 niflumic acid에 의하여 차단되었다. 칼슘 chelator인 BAPIA와 IP$_3$ 수용체 길항제인 heparin을 세포내 injection에 의하여 차단되었다. 또한 active phospholipase C inhibitor(PLC)인U-73122를 세포 바깥에 전처리할 경우에도 GTS의 작용이 부분적으로 억제되는 것으로 나타났다. 백일해 독소를 전처리할 경우GTS의 작용은 억제되지 않은 것으로 나타났으나, GTP analog인 GTP${\gamma}$S를 세포내 injection할 경우 GTS의 작용은 억제되는 것으로 나타났다. 이러한 연구 결과는 GTS가 oocytes세포막 성분과 상호 작용에 의하여 $Ca^{2+}$-activated Cl- channel이 열리도록 하고, 이 과정에 PLC활성 및 백일해 독소에 민감하지 않은 G단백질활성 및 IP3에 민감한 세포내 $Ca^{2+}$-activated로부터 칼슘 방출을 유도하는 것으로 나타났다났다

Background: Coffee extract has been investigated by many authors, and many minor components of coffee are known, such as polyphenols, diterpenes (kahweol and cafestol), melanoidins, and trigonelline, to have anti-inflammatory, anti-oxidant, anti-angiogenic, anticancer, chemoprotective, and hepatoprotective effects. Therefore, it is necessary to know its pharmacological effect on hepatocytes which show the most active cellular regeneration in body. Methods: In order to determine whether coffee extract has a beneficial effect on the liver, 20 C57BL/6J mice were intraperitoneally injected once with dialyzed coffee extract (DCE)-2.5 (equivalent to 2.5 cups of coffee a day in man), DCE-5, or DCE-10, or normal saline (control), and then followed by histological observation and IP-HPLC (immunoprecipitation high performance liquid chromatography) over 24 h. Results: Mice treated with DCE-2.5 or DCE-5 showed markedly hypertrophic hepatocytes with eosinophilic cytoplasms, while those treated with DCE-10 showed slightly hypertrophic hepatocytes, which were well aligned in hepatic cords with increased sinusoidal spaces. DCE induced the upregulations of cellular proliferation, growth factor/RAS signaling, cellular protection, p53-mediated apoptosis, angiogenesis, and antioxidant and protection-related proteins, and the downregulations of NFkB signaling proteins, inflammatory proteins, and oncogenic proteins in mouse livers. These protein expression changes induced by DCE were usually limited to the range ± 10%, suggesting murine hepatocytes were safely reactive to DCE within the threshold of physiological homeostasis. DCE-2.5 and DCE-5 induced relatively mild dose-dependent changes in protein expressions for cellular regeneration and de novo angiogenesis as compared with non-treated controls, whereas DCE-10 induced fluctuations in protein expressions. Conclusion: These observations suggested that DCE-2.5 and DCE-5 were safer and more beneficial to murine hepatocytes than DCE-10. It was also found that murine hepatocytes treated with DCE showed mild p53-mediated apoptosis, followed by cellular proliferation and growth devoid of fibrosis signaling (as determined by IP-HPLC), and subsequently progressed to rapid cellular regeneration and wound healing in the absence of any inflammatory reaction based on histologic observations.
