The water extracts of Jagamcho-tang has been used for treatment of arrhythmia and palpitation in oriental traditional medicine. Brain is provided with blood flow by heart. Jagamcho-tang has been studied on ischemia and infarction in heart. However, little is known about the mechanism by which the water extracts of Jagamcho-tang rescues brain cells from ischemic damages. To elucidate the protective mechanism on ischemic induced cytotoxicity, the effects of Jagamcho-tang on ischemia induced cytotoxicity and generation of nitric oxide(NO) are investigated in C6 glioma cells. Jagamcho-tang induce NO in a dose dependent manner up to 2.5mg/ml in C6 glioma cells. The pretreatment of Jagamcho-tang protect sodium nitroprusside(SNP) (2mM) induced cytotoxicity. This effect of Jagamcho-tang is mimicked by treatment by pretreatment of SNP($100{\mu}M$), an exogenous NO donor. NG-monomethyl-L-arginine($N^{G}MMA$), a specific inhibitor of nitric oxide synthase (NOS), significantly blocks the protective effects of Jagamcho-tang on cell toxicity by ischemia. In addition, lipopolysaccharide(LPS) and phorhol 12 myristate 13-acetate(PMA) treatment for 72h in C6 glial cells markedly induce NO, but treatment of the cells with the water extracts of Jagamcho-tang decrease nitrite formation in a dose dependent manner. In addition, LPS and PMA treatment for 72h induce severe cell death and LDH release into medium in C6 glial cells. However treatment of the cells with the water extracts of Jagamcho-tang dose not induce significant changes compare to control cells. Furthermore, the protective effects of the water extracts of Jagamcho-tang is mimicked by treatment of $N^{G}MMA$. Taken together, I suggest that the protective effects of the water extracts of Jagamcho-tang against ischemic brain damages may be mediated by regulation of iNOS during ischemic condition.

Activated T helper 2 (Th2) immune function is hallmark of various allergic diseases. We investigated the anti-allergic effect of Jagamcho-tang extract(JE) on ovalbumin(OVA)-induced atopic dermatitis mice model and OVA-stimulated splenocytes isolated from the mice. Mice were intraperitoneally injected OVA/alum solution 2 times at interval of 14 days, followed by oral administration of JE for 7 days. After administration, mice were subcutaneously injected with OVA in ear. JE treatment reduced ear swelling and infiltration of inflammatory cells in ear. Serum levels of interleukin(IL)-4 and immunoglobulins, such as total-IgE and OVA-specific IgE, were decreased in JE treated group. Furthermore, JE treatment decreased OVA-induced Th2-associated cytokines like IL-4, IL-5 and IL-13 mRNA levels in splenocytes. In conclusion, JE reduced allergic immune response via IgE production and Th2 response in OVA-sensitized mice, suggesting that JE could be useful prescription for allergic diseases including atopic dermatitis.

Objectives: The purpose of this study is to report the clinical effectiveness of Korean medicine treatment on postmenopausal syndrome. Methods: The patient with postmenopausal syndrome with palpitation was treated with Korean medicine treatment during 14 days of hospitalization. The patient received Korean medicine treatment including herbal medicine, acupuncture and moxibustion. The effect of treatment on postmenopausal syndrome was evaluated through the Numeric Rating Scale (NRS) and questionnaire. Palpitation and arrhythmia was evaluated by Electrocardiogram (ECG) and manual pulse diagnosis three times a day. Result: After the treatment, the clinical postmenopausal symptoms of palpitation and hot flush were improved. Also, ECG's result was improved ventricular premature contraction to normal ECG. Conclusions: This case report proved that the Korean medicine treatment may be effective for improving postmenopausal syndrome with palpitation and hot flush. However, further clinical study is needed in the future to prove the effectiveness of Korean medicine treatment for postmenopausal syndrome with palpitation and hot flush.
