In previous works, we reported that Hyp (hyperin) showed strong analgesic effect, and inhibited discharges induced by multianalgesics, but without anesthetic action. In this study, the analgesic mechanism of Hyp was further investigated. In the tail-flick test in mice, EGTA was shown to markedly enhance the analgesic effect of Hyp and shift the dose-effect(More)
AIM To study the protective and antiperoxidative effects of hyperin (hyperoside; quercetin-3-O-galactoside; Hyp) on myocardial ischemia/reperfusion. METHODS The rabbit anterior descenging branch of left coronary artery was occluded for 60 min and then released to allow reperfusion for 20 min. Hemodynamics (LVP, LV +/- dp/dt) and electrocardiogram (ECG,(More)
Hyperin(Hyp) was shown to inhibit the positive inotropic action of calcium ion on the isolated papillary muscles and shift the dose response curve of calcium ion to the right. As a plot lg(x-1) vs -lg(B) resulted in straight lines with slopes of -0.625. On the action potentials of guinea pig myocardial cells, Hyp markedly decreased the duration of plateau(More)
AIM To study the effects of hyperin (Hyp) on free intracellular calcium concentration ([Ca2+]i) of brain cells. METHODS The neonatal rat brain cells were dissociated. [Ca2+]i in presence and absence of extracellular high K+, L-glutamic acid (Glu), 5-hydroxytryptamine (5-HT), and norepinephrine (NE) were assayed with Fura 2-AM. RESULTS The resting(More)
Nine microsatellite DNA markers were developed and characterized for Siganus oramin by the 5'-anchored polymerase chain reaction technique. A total of 42 alleles were identified in 30 individuals, and the number of alleles per locus ranged from 3 to 7, with an average of 4.7. The observed and expected heterozygosity per locus ranged from 0.5333 to 1.0000(More)
DNA barcoding is an effective method for identifying species by analyzing one or a few short standardized DNA sequences. In this study, we examined the utility of mitochondrial cytochrome oxidase subunit I (COI) sequences as a DNA barcode for the identification of six species belonging to the genus Thryssa: T. dussumieri, T. hamiltonii, T. kammalensis, T.(More)
