UNLABELLED Eosinophils have been implicated in a broad range of diseases, most notably allergic conditions (e.g. asthma, rhinitis and atopic dermatitis) and inflammatory diseases. These diseases are characterized by an accumulation of eosinophils in the tissue. Defining the mechanisms that control eosinophil recruitment is fundamental to understanding how(More)
This study was conducted to compare the effects of low frequency electroacupuncture (EA) and high frequency EA at acupoint ST36 on the production of IgE and Th1/Th2 cytokines in BALB/c mice that had been immunized with 2,4-dinitrophenylated keyhole limpet protein (DNP-KLH), as well as to investigate the difference in the immunomodulatory effects exerted by(More)
Acori graminei Rhizoma is one of the best-known traditional herbal medicines frequently used for the treatment of cardiovascular symptoms in Asian countries. The anti-ischemic effect of Acori graminei Rhizoma on ischemia-induced isolated rat heart was investigated through analysis of changes in perfusion pressure, aortic flow, coronary flow, and cardiac(More)
To find new pancreatic lipase (triacylglycerol acylhydrolase, EC inhibitors from natural products, 61 medicinal plants from Korea were screened for their antilipase activity for prevention of obesity. Dried and powdered plants were extracted three times with EtOH and extracts were obtained by removal of the solvent in vacuo. Lipase activity was(More)
To identify effective herb to treat obesity, we screened 115 herbal extracts for inhibition of porcine pancreatic lipase (triacylg-ycerol acylhydrolase, EC activity in vitro. Of the extracts tested, Cudrania tricuspidata leaves exhibited the most pronounced inhibitory effect on lipase activity with an IC(50) value of 9.91 μg/mL. Antilipid(More)
Cuticular nanostructures found in insects effectively manage light for light polarization, structural color, or optical index matching within an ultrathin natural scale. These nanostructures are mainly dedicated to manage incoming light and recently inspired many imaging and display applications. A bioluminescent organ, such as a firefly lantern, helps to(More)
Previously, we demonstrated that electoracupuncture (EA) suppressed allergic reactions in DNP-KLH immunized mice. In this study, the mechanisms by which EA induces immunomodulation in the immunized mice were evaluated by genome-wide microarray analysis. The anti-allergic effects of EA in DNP-KLH immunized mice were confirmed by analyzing antigen specific(More)
Aim. To investigate whether dyspepsia symptoms differ depending on the presence or absence of cold hypersensitivity in the hands and feet (CHHF). Methods. In all, 6044 patients were recruited and provided with a questionnaire about CHHF and dyspepsia. Based on their responses, subjects were divided into a CHHF group (persons who noted cold sensations; n =(More)
BACKGROUND The cold/heat questionnaire is one of the most actively developed patient diagnostic tools in traditional Korean medicine (hereafter abbreviated as TKM) because of its objectivity. Unfortunately, the existing questionnaires contain too many items to hold the respondent's attention. In the current study, we aimed to develop an optimized cold/heat(More)
Our previous study demonstrated that successive electroacupuncture (EA) at ST36 acupoint reduces IgE production in BALB/c mice immunized with 2,4-dinitrophenylated keyhole limpet protein (DNP-KLH) by suppression of the Th2 cell lineage development. Here, we report that pretreatment of phentolamine (alpha-adrenoceptor antagonist, 10mg/kg, i.p.) completely(More)
