ABSTRACT
Objective: the alteration of hormones regulating sodium andwater status is related to renal failure in obstructive jaundice (OJ).Experimental design: OJ was induced by common bile ductligation. Samples were obtained from the control (SO) and OJgroups at 24 and 72 hours, and at 7 days. Different parametersrelated to biliary obstruction, liver and renal injury, and vasoactivemediators such as renin, aldosterone, endothelin-1 (ET-1) andprostaglandin E2 (PGE2) were studied.Results: bile duct ligation caused an increase in total bilirubin(p < 0.001) and alkaline phosphatase (AP) (p < 0.001). The SOand OJ groups had the same values for diuresis, renin, and creatinineclearance at 24 h. However, animals with OJ had a lowersodium concentration in urine than SO animals (p < 0.01), as wellas an increase in aldosterone levels (p < 0.03). ANP levels weremoderately increased during OJ but did not reach statistical significancewhen compared to the SO group. In contrast, OJ animalsshowed a rise in serum ET-1 concentration (p < 0.001) and increasedPGE2 in urine (p < 0.001).Conclusions: biliary obstruction induced an increase in ET-1release and PGE2 urine excretion. These hormones might play arole during the renal complications associated with renal disturbancesthat occur during OJ(AU)
