Polydatin Attenuates Carbachol-induced Contraction of Guinea Pig Gallbladder
View through CrossRef
The aim of this study was to determine whether polydatin, a glucoside of resveratrol isolated from the root of Polygonum cuspidatum, warranted development as a potential therapeutic for ameliorating the pain originating from gallbladder spasm disorders and the underlying mechanisms. Guinea pig gallbladder smooth muscles were treated with polydatin and specific inhibitors to explore the mechanisms underpinning polydatin-induced relaxation of carbachol-precontracted guinea pig gallbladder. Our results shown that polydatin relaxed carbachol-induced contraction in a dose-dependent manner through the nitric oxide/cyclic guanosine monophosphate/protein kinase G and the cyclic adenosine monophosphate/protein kinase A signaling pathways as well as the myosin light chain kinase and potassium channels. Our findings suggested that there was value in further exploring the potential therapeutic use of polydatin in gallbladder spasm disorders.

The role of protein kinase C in the regulation of gallbladder sodium transport during gallstone formation
Background and aims. Gallbladder Na⁺ and water absorption increases prior to gallstone formation and promotes cholesterol nucleation. Na⁺/H⁺ exchange (NHE) is a major pathway for g...
