dc.description.abstract | Background/Aims: Common bile duct ligation (CBDL) in the guinea pig is a well-defined model of acalculous cholecystitis. Nitric oxide (NO) mediates smooth muscle relaxation by stimulating the activity of soluble guanylate cyclase. The aim of this study was to determine whether the NO/cyclic guanosine monophosphate pathway plays a role in gallbladder relaxant response after CBDL. Methods: Relaxant response of gallbladder muscle strips from CBDL and sham-operated guinea pigs was studied in vitro. Animals were treated with saline, aminoguanidine or an aminoguanidine+L-arginine combination in vivo. Concentration-response curves of papaverine, diethylamine/NO, YC-1, sildenafil and amrinone were obtained and relaxations in each group were calculated as the percent of the contractions induced by carbachol (10(-6) M). Results: There was a significant decrease in the gallbladder muscle relaxant responses to these substances in CBDL and aminoguanidine groups compared with sham surgical controls. The decreased relaxant response was reversed by aminoguanidine+L -arginine but not by aminoguanidine alone. Conclusion: Decreased relaxant responses might be due to the reduced guanylate cyclase enzyme activity, but further studies are required. Copyright (C) 2009 S. Karger AG, Basel | en_US |
