OBJECTIVES The aim of the study was to evaluate berberine-induced bidirectional regulation on the contractility of jejunum. METHODS Different low and high contractile states of isolated jejunal segment from rat were established to investigate the effects of berberine. KEY FINDINGS Stimulatory effects on jejunal segment were exerted by berberine in six(More)
Genistin belongs to isoflavones. Based on the facts that genistin exerts inhibitory effects on the contractility of vascular smooth muscle,the present study was designed to characterize the effects of genistin on intestinal contractility and evaluate its potential clinical implication. Ex vivo [isolated jejunal segment (IJS) of rat], in vitro, and in vivo(More)
The determination of hormone-binding sites in plants is essential in understanding the mechanisms behind hormone function. Salicylic acid (SA) is an important plant hormone that regulates responses to biotic and abiotic stresses. In order to label SA-binding sites in plant tissues, a quantum dots (QDs) probe functionalized with a SA moiety was successfully(More)
In this study, we propose that diprophylline exerts bidirectional modulation (BM) on the isolated rat jejunal segment depending on its contractile state. The results supported the hypothesis. Diprophylline (20 µM) exerted stimulatory effects on the contractility of jejunal segment in six low contractile states while inhibitory effects in six high(More)
Nobiletin, a citrus polymethoxylated flavone, exhibits multiple biological properties including anti-inflammatory, anti-carcinogenic, and anti-insulin resistance effects. The present study found that nobiletin exerted significant stimulatory effects on the contractility of isolated rat jejunal segments in all 6 different low contractile states, and(More)
This study was designed to characterise the effects of evodiamine on intestinal contractility and reveal the correlated mechanisms. Evodiamine (2.5-80.0 μM) increased normal jejunal contractility and jejunal hypocontractility established under a variety of experimental conditions. Evodiamine-exerted stimulatory effects were blocked by the L-type Ca(2+)(More)
