As apart of our continuing search for antistroke agents from the herbal medicinal resources, we examined in vitro, ex vivo and in vivo the possibility of Sunghyangjunggisan and its ingradients as a novel antithrombotic agent. In vitro ADP- and collagen-induced rat platelet aggregations were potently inhibited by Arisaematis Rhizoma, Cinnamomi Cortex and Zingiberis Rhizoma in a dose-dependent manner, but not by Sunghyangjunggisan. However, Sunghyangjunggisan significantly inhibited ex vivo rat platelet aggregation. Arisaematis Rhizoma, Atractylodis Rhizoma Alba, and Pinelliae Rhizoma also significantly inhibited ex vivo rat platelet aggregation. Sunghyangjunggisan, Alpiniae Fructus and Zingiberis Rhizoma showed significant protection from death due to pulmonary thrombosis in mice. Therefore, Sunghyangjunggisan can express the antithrombotic action, when it is orally administered.

Objectives: The present study is focused on the inhibitory effect of the rhizome hexane fraction extract of Zingiberis Rhizoma Crudus (ginger hexan extract; GHE) on the production of inflammatory mediators such as NO, $PGE_2$, and proinflammatory cytokines in lipopolysaccharide (LPS)-stimulated BV2 cells, a mouse microglial cell line. Methods: We separated the hexane fraction from Zingiberis Rhizoma Crudus's methanol extract. The inhibitory and anti-inflammatory effect of GHE was examined on microglial activation. Results: GHE significantly inhibited the excessive production of NO, $PGE_2$, TNF-${\alpha}$, and IL-1${\beta}$ in LPS-stimulated BV2 cells. In addition, GHE attenuated the mRNA expressions and protein levels of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and proinflammatory cytokines. Conclusion: The anti-inflammatory properties of GHE may make it useful as a therapeutic candidate for the treatment of human neurodegenerative diseases.

The effects of Bogi, Boyang and Onri herbs on glutamate receptor using nystatin perforated patch clamp under voltage clamp were investigated and the following results was obtained. Ginseng radix and Astragali radix were chosen as Bogi herbs. Cervi cornu and Boshniakiae herba were used as Boyang herbs. Aconiti tuber and Zingiberis rhizoma were selected as Onri herbs. 1. $10^{-6}M$ of glycine brought about the increase of the ion currents by Astragali radix. Cervi cornu. Boshniakiae herba and Aconiti tuber to a minute extent that has no experimental meaning. 2. It was assumed that Bogi herb had no effect on glutamate receptor since the ion currents of Ginseng radix and Astragali radix that are Bogi herbs had not been inhibited to a great extent by D-AP5 and CNQX. 3. Boyang herbs were seem to have meaningful relationship with non-NMDA receptor since the ion currents by Cervi cornu and Boshniakiae that are Boyang herbs were inhibited by CNQX but not inhibited to a meaningful extent by D-AP5. 4. D-AP5 had not a significant effect on the ion currents activated by Onri herbs such as Aconiti tuber and Zingiberis rhizoma. CNQX had a significant effect on the ion currents of Aconiti tuber but no effect on the ion currents of Zingiberis rhizoma. Therefore, it seemed that Aconiti tuber had a relationship with non-NMDA receptor while Zingiberis rhizoma had no relationship with glutamate receptor. In summary, Bogi, Boyang and Onri herbs had different effects through different mechanisms on glutamate receptor. Hence it was believed that. through experiments on acetylcholine receptor new classification could be made.

Objectives : The objective of this study was to investigate the effects of Zingiberis Rhizoma Pharmacopuncture(ZP) at GB30 and ST36 in neuropathic pain induced SD rats by the block of Transient Receptor Potential Vanilloid 1(TRPV1). Methods : Neuropathic pain in rats was induced by tibial and common peroneal nerve transection of right leg. The rat subjects were divided into 6 groups : normal(Nor, n=5), control(Con, n=5), neuropathic pain plus 2 mg/kg ZP injection at GB30 and ST36(ZP-A, n=5), 10 mg/kg ZP(ZP-B, n=5), 20 mg/kg ZP(ZP-C, n=5) and 0.45 mg/kg Tramadol(Tra, n=5). Three days after the surgery, injections were administered once a day for 17 days. Withdrawal response of neuropathic rats' legs were measured by stimulating the paw of Right leg with von frey filament, acetone and radient heat on day 3, 7, 11, 15, 19 after surgery. After all treatments were completed, c-Fos in the midbrain central gray and TRPV1 & TRPA1 of DRG(L5) were analyzed. Results : Groups ZP-B and ZP-C showed a meaningful decrease in the withdrawal response of mechanical allodynia, thermal hyperalgesia and cold allodynia compared to the control group(p<0.05, p<0.01, p<0.001). Groups ZP-B and ZP-C showed a meaningful decrease in the expression of c-fos and TRPV1 protein level compared to the control group(p<0.05, p<0.01, p<0.001). Conclusions : These results suggest that Zingiberis Rhizoma Pharmacopuncture at GB30 and ST36 could decrease mechanical & cold allodynia and thermal hyperalgesia by block the TRPV1 on the model of neuropathic pain.

Zingiberis Rhizoma (ZR, Zingiberaceae) is one of the foods for a long time and contains various biological activities including anti-cancer, anti-inflammatory, anti-oxidant, and anti-platelet activities. The present study was to compare the amount of 6-gingerol in the 70% ethanol extracts of non-processed ZR and processed ZR by roasting using a high-performance liquid chromatography equipped with photodiode array detector. The 6-gingerol was separated on a Gemini $C_{18}$ analytical column ($5{\mu}m$, $4.6{\times}250mm$) using two mobile phase consisting of distilled water and acetonitrile. The flow rate was 1.0 mL/min and injection volume was $10{\mu}L$. In non-processed ZR sample, the amount of the 6-gingerol was 0.43% and the amount of the marker compound in processed ZR samples by roasting were 0.16-0.55%.

Microglia have multiple functions in regulating homeostasis of the central nervous system. Microglia cells have been implicated as active contributors to neuron damage in neurodegenerative disorders. In this study, medicinal plant extracts (MPEs) were used to evaluate the cell-death induction effect in microglia BV-2 cells. Among 35 MPEs tested in this study, 4 MPEs showed less than a 30% cell survival after 24 hours of incubation. These were Foeniculi Fructus, Forsythiae Fructus, Zingiberis Rhizoma and Hedera Rhombea. The concentration showed that 50% cell death ($IC_{50}$) occurred with 33, 83, 67 Ed highlight: Please confirm wording, and $81{\mu}/ml$, respectively. For further study, we chose Zingiberis Rhizoma (ZR) which showed a reasonably low $IC_{50}$ value and an induction of cell death in a relatively narrow range. Western blot analysis showed that ZR-treated cells showed activation of caspase-3 and cleavage of PARP Ed highlight: When an acronym is first presented it needs to be spelled out in both dose- and time-dependent manners. However, the level of Bcl-2 and Bax were not changed by ZR-treatment in BV-2 cells. These results suggest that ZR-induced apoptosis in BV-2 cells occured through caspase-3 activation. The results also suggested that ZR may be useful in developing treatments for neurodegenerative diseases.

Glutamate-induced oxidative injury contributes to neuronal degeneration in many central nervous system (CNS) diseases, such as Parkinson's disease, Alzheimer's disease, epilepsy and ischemia. Inducible heme oxygenase (HO)-1 acts against oxidants that are thought to play a role in the pathogenesis of these diseases. NNMBS098, a composition comprising the water insoluble of the 70% EtOH extract of Zingiberis Rhizoma, showed the potent neuroprotective effects on glutamateinduced neurotoxicity by induced the expression of heme oxygenase (HO)-1 and increased HO activity in the mouse hippocampal HT22 cells. Furthermore, NNMBS098 caused the nuclear accumulation of nuclear factor E2-related factor 2 (Nrf2) in mouse hippocampal HT22 cells. In addition, we found that treatment with c-Jun N-terminal kinase (JNK) inhibitor (SP600125) reduced NNMBS098-induced HO-1 expression and NNMBS098 also increased JNK phosphorylation. Therefore, these results suggest that NNMBS098 increases cellular resistance to glutamate-induced oxidative injury in mouse hippocampal HT22 cells, presumably through JNK pathway-Nrf2-dependent HO-1 expression.

Objectives : We analyzed the principle of compatibility of socheongnyong-tang and expanded the range of application in clinical practice. Methods : Socheongnyong-tang was analyzed by the compatibility principle through the system of chief, deputy, assistant, and envoy, but the basic formulas of "Discussion of Cold Damage" and "Synopsis of the Golden Chamber" was used. Results : Socheongnyong-tang treats exterior wind-cold and interior water accumulation. Exterior wind-cold is treated mainly by exterior-releasing herbs constituting mahwang-tang and gyeji-tang in "Discussion of Cold Damage", and interior water accumulation is treated mainly by retained fluid-resolving herbs constituting yeonggamomigangsinha-tang, yeonggamomigagangsinbanhahaengin-tang and yeonggamomigagangsinbanhaengdaehwang-tang in "Synopsis of the Golden Chamber". Depending on the weight of exterior wind-cold and interior water accumulation, the disease condition is classified as a case where exterior wind-cold is heavier than interior water accumulation, a case where exterior wind-cold is lighter than interior water accumulation, and a case where it is equivalent. When exterior wind-cold is heavier than interior water accumulation, chief herbs are Ephedrae Herba and Cinnamomi Ramulus of exterior-releasing herbs series and deputy herbs are Zingiberis Rhizoma and Asari Radix et Rhizoma of retained fluid-resolving herbs series. When exterior wind-cold is equal to the disease condition of interior water accumulation, chief herbs are Ephedrae Herba of exterior-releasing herbs series and Zingiberis Rhizoma of retained fluid-resolving herbs series, and deputy herbs are Cinnamomi Ramulus of the exterior-releasing herbs series and Asari Radix et Rhizoma of retained fluid-resolving herbs series. When exterior wind-cold is lighter than interior water accumulation, chief herbs are Zingiberis Rhizoma and Asari Radix et Rhizoma of retained fluid-resolving herbs series and deputy herbs are Ephedrae Herba and Cinnamomi Ramulus of exterior-releasing herbs series. In any case, assistant herbs are Pinelliae Rhizoma, Paeoniae Radix alba, and Schisandrae Fructus, and envoy herb is Glycyrrhizae Radix preparata. Conclusions : In conclusion, socheongnyong-tang must differently formulate the system of chief, deputy, assistant, and envoy according to the grade of exterior wind-cold and interior water accumulation. These results suggest that socheongnyong-tang can be applied flexibly when applied in clinical practice to enhance the therapeutic effect.
