Objective : This study was carried out to investigate protective effects of Pharmacopuncture Solutions (PSs) made by Carthmi Flos (CF), Cnidii Rhizoma (CR) and Astragali Radix (AR) on C6 glioma cells Methods : We investigated the effects of PSs on proliferation rates and types of C6 cells, and also investigated the effects on LDH release. In addition, protective effects of PSs on oxidative stress induced by hydrogen peroxide and SOD-like activities were also investigated. Results : PSs made by CF, CR and AR did not show cytotoxicity in various concentrations. CF-PS and AR-PS elevated levels of proliferation rates significantly. Treatment with CF-PS lowered level of LDH release in C6 cells. In addition, CF-PS and CR-PS showed protective effects on cell death induced by hydrogen peroxide respectively. Finally, CF-PS group showed high level of SOD-like activity compared to that in CR-PS group. Conclusion : These results suggest that CF-PS can accelerate proliferation of neuroglial cells, and has protective action against oxidative stress, which was involved in anti-oxidative effects such as SODlike activities. In addition, CR has protective effects against oxidative stress, and AR can accelerate proliferation of neuroglial cells.

Chemokines are important for the recruitment of leukocytes, which is essential in host defense to the sites of infection. The thymus and activation-regulated chemokine (TARC) is a CC chemokine which potentially plays a role via a paracrine mechanism in the development of allergic respiratory diseases. Objectives : The objective of this study is to investigate the effect of Ephedrae Herba Herbal Acupuncture Solution(EHS) on the secretion of TARC of human bronchial epithelial cell. Methods : Enzyme-linked immunosorbent assay (ELISA) was performed to detect the secretion of TARC. The cytotoxicity was measured by MTT assay. Results : EHS significantly inhibited the secretion of TARC with a dose-dependant manner. The effective dosage did not have the cytotoxicity on human bronchial epithelial cell. Conclusion : Results of our study imply that EHS would play an important role in modulation of TARC in human bronchial epithelial cells by MTT assay.

Objective: This study was undertaken to evaluate the role of lipid peroxidation in oxidant-induced apoptosis and effect of JS on the apoptosis in opossum kidney (OK) cells, an established renal proximal tubular cells. Methods : Exposure of cells to 0.1mM tBHP for 2hr did not induce apoptosis, but subsequent incubation in normal culture medium for 18hr after tBHP treatment induced apoptotic cell death which is dependent of tBHP concentration. Results : JS decreased tBHP-induced apoptotic cell death in a dose-dependent fashion and at concentrations higher than 0.01 mg/ml completely prevented the apoptosis. tBHP-induced apoptosis was prevented by the lipid soluble antioxidant N,N'-diphenyl-p-phenylenediamine (DPPD) and water-soluble antioxidant Trolox. tBHP increased lipid peroxidation, which was inhibited by JS and DPPD. tBHP-induced DNA damage was prevented by JS and DPPD. Conclusion : These results indicate that tBHP induces apoptosis through a lipid peroxidation-dependent mechanism and JS exerts the protective effect against the apoptosis by preventing peroxidation of membrane lipids.

It has been investigated about aging theory. However, aging mechanism still remains to be unknown. Aging and aging related diseases might be due to oxidative damage and these were modifiable by genetic and environmental factors. For designing an optimal medical treatment and countermeasure against aging and aging related disease, it is necessary to understand the aging mechanism. Acetylcholine(Ach) plays an important role in memory. If someone doesn't have enough Ach, he has a tendency to catch a Alzheimer's disease. Corydalis tuber has been clinically used to treat heart disease, gastrointestinal disease and other diseases including endocrine disease in Oriental medicine. The purpose of this article is to investigate the inhibitory effect on Acetylcholinesterase and scavenging effects on NO, DPPH of Corydalis tuber Acua-acupuncture solution(CTAS). The results are summerised as follows; 1. There is a significant inhibitory effect of $0.01mg/m{\ell}$ CTAS group at 20, 30, 60 minutes and $0.1mg/m{\ell}$ CTAS group at 10, 20, 30, 60 minutes on AchE. 2. There is no significant scavenging effect of CTAS on NO. 3. There is a significant scavenging effect of $0.1mg/m{\ell}$ and $0.01mg/m{\ell}$ CTAS group at 10 minutes but there is no significant scavenging effect at 20, 30, 60 minutes on DPPH. There is a significant scavenging effect of $1mg/m{\ell}$ CTAS group at 10, 20, 30, 60 minutes on DPPH.

Objective: Bee Venom(BV) has been used for various kinds of inflammatory or painful conditions in Oriental Medicine clinics, and there publishes reports on its therapeutic effects and the probable mechanism of those therapeutic effects, where CDs and cytokines plays important role. This study investigated the influences of bee venom on the expressions of CDs and cytokines of HMC cell line Methods: In this study we analysed the expression profile of HMC cell line treated with BV of 10-2ug/ml in relation to that of HMC cell line treated with vehicle by way of CD/cytokine microarray hybridization with 342 genes on it. Results: There were no upregulated genes by more than 3 fold, while there showed some downregulated genes by less than 1/3 fold as follows: colony stimulating factor 2, CD122, IL-7, CD112, TNF-alpha, CD138, CD166, TGFbetaR2, CD42b, CD62L, CD111, interleukin 10 receptor alpha, colony stimulating factor 1(macrophage), CD38 antigen(p45), CD121a, CD33 antigen(gp67), colony stimulating factor 1 receptor, B cell linker protein (SLP65) mRNA, CD94, alanyl(membrane) aminopeptidase, immunoglobulin(CD79A) binding protein 1, CD205, CD241, CD207, CDw121b, integrin alpha L(CD11a), integrin beta 1(CD29), CD91, CD42b. Conclusions: Bee venom treatment induced downregulation of some CDs or cytokines including $TNF-{\alpha}$. IL-1R with its possible implication in an antiinflammatory action of BV. Further research on expression profile changes induced by BV treatment is expected.

Objective : To study anti-inflammatory, analgesic effect and molecular biological mechanism of honey bee venom for aqua-acupuncture, human mast cell line(HMC-1) and human glioma cell line(HS683) were treated with bee venom. Methods : Cell viability of bee venom was tested by 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) asssay. To explore whether anti-inflammatory, analgesic effects of bee venom are associated with the control of gene expression, quantitative RT-PCR analysis of inflammation and pain related genes was performed. Results : The MTT assay demonstrated that cell viability was not decreased by treatment with 10-9 ug/ml bee venom in comparison with 10-2, 10-3, 10-4, 10-5, 10-6, 10-7, 10-8, 10-9, 10-10 and 10-11 ug/ml. sPLA2 and COX-l were down-regulated by treatment with 10-9 ug/ml bee venom in HS683 Cell line in comparison with control. COX-2 was up-regulated by treatment with 10-9 ug/ml bee venom in HS683 Cell line and HSP-2 was up-regulated by treatment with 10-9 ug/ml bee venom in HMC-1 Cell line in comparison with control. sPLA2, COX-1 and COX-2 showed no significant regulation in HMC-1 Cell line and cPLA2 also showed no significant regulation in both HMC-l and HS683 Cell line between control and bee venom treated group.

Objective : This study was performed to determine if Scutellaria balicalensis Georgi extract (SbGE) prevents oxidant-induced membrane transport dysfunction in renal tubular cells. Methods : Membrane transport function was estimated by measuring $Na^+$-dependent inorganic phosphate transport in opossum kidney (OK) cells. $H_2O_2$ inhibited phosphate transport in a dose-dependent manner. Results : The inhibitory effect of $H_2O_2$ was significantly prevented SbGE over concentration range of 0.005-0.05%. $H_2O_2$ caused ATP depletion, which was prevented by SbGE. $H_2O_2$ induced the loss of mitochondrial function as evidenced by decreased MTT reduction and its effect was prevented by SbGE. The $H_2O_2$-induced inhibition of phosphate transport was not affected by a potent antioxidant DPPD, but the inhibition was prevented by an iron chelator deferoxamine, suggesting that $H_2O_2$ inhibits $Na^+$-dependent phosphate transport via an iron-dependent nonperoxidative mechanism in renal tubular cells. Conclusion : These data suggest that SbGE may exert the protective effect against oxidant-induced membrane transport dysfunction by a mechanism similar to iron chelators in renal epithelial cells. However, furher studies should be carried out to find the active ingredient(s) of SbGE that exerts the protective effect.
