The present study was conducted to determine whether blockage of both N-methyl-D-aspartate (NMDA) and alpha-amino-3-hydroxy-5-methylisoxazole-4-proprionic acid/kainate (AMPA/KA) receptors influences the induction of low frequency electroacupuncture (EA) analgesia. Although neither intrathecal injection of NMDA antagonist D-2-amino-5-phosphonopentanoic acid(More)
The phosphorylation changes of nociceptive signaling proteins in the spinal cord dorsal horn (SCDH) are important in creating exaggerated pain following peripheral inflammation. Electroacupuncture (EA) has been widely used to relieve acute and chronic inflammatory pain in human and experimental pain models. In the present(More)
We investigated expressional changes of spinal glutamate receptors by electroacupuncture (EA) in an inflammatory animal model. Inflammation was induced by an intraplantar injection of complete Freund's adjuvant (CFA) into the hindpaw of male Sprague-Dawley rats. Bilateral EA stimulation at 2, 15 and 120 Hz was applied at those acupoints corresponding to(More)
The present study was designed to assess the potential inhibitory activity of curcumin on the alpha-melanocyte stimulating hormone (alpha-MSH)-stimulated melanogenesis signal pathway in B16F10 melanoma cells. The molecular mechanism of curcumin-induced inhibitory activity on the alpha-MSH-stimulated melanogenesis signal pathway, including expression of(More)
We investigated the anti-inflammatory effects of electroacupuncture (EA) on carrageenan-induced inflammatory model in association with peripheral and spinal COX-2 expression. EA with 2, 15 and 120 Hz, especially 2 Hz, had significant inhibitory effects on the developing of edema and hyperalgesia, which was measured in 30-min intervals after carrageenan(More)
We investigated the effects of aqueous extract from Platycodi radix (AEPR), a traditional drug used to treat acute lung inflammatory disease, on lipopolysaccharide (LPS)-induced inflammation in A549 human cultured airway epithelial cells. Nuclear factor-kappaB (NF-kappaB) and its inhibitory regulator, inhibitory kappaB (I-kappaB), play crucial roles in(More)
A novel de-interlacing algorithm is proposed to accomplish high quality video format conversion. In the proposed scheme, bi-directional motion estimation (ME) is performed between the same parity fields, i.e., the previous and next fields. The bi-directional motion estimation is composed of initial motion vector estimation, motion vector smoothing using(More)
The present study investigated the role of inhibitor of protein phosphatases 1 and 2A on the modulation of the phosphorylation of the spinal N-methyl-D-aspartate receptor (NMDAR) NR1 and NR2B subunits following electroacupuncture (EA) stimulation in rats. Bilateral 2Hz EA stimulations with 1.0 mA were delivered at those acupoints corresponding to Zusanli(More)
