Comparative StudyObstructive jaundice in rats: cause of spatial memory deficits with recovery after biliary decompression.
Children with end-stage liver disease have been found to have cognitive deficits. The aim of this study was to examine whether cholestatic jaundice causes spatial deficits in rats and if these cognitive deficits are reversed by biliary drainage. Rats were randomly divided into three groups. ⋯ After biliary decompression for 1 week, the serum albumin concentration in the TBD group still did not return to the level of the SHAM group. The results of this study suggest that long-term cholestasis results in spatial memory deficits in rats that correlate with anemia and hyperbilirubinemia encephalopathy. Early biliary decompression of obstructive jaundice improves spatial memory deficits, possibly related to the recovery of the serum ammonia and hemoglobin levels.
