Ethnopharmacological Relevance: Danshen, root of Salvia miltiorrhiza (SM), has been traditionally used in Chinese medicine for the treatment of heart, abdomen, gurgling in the intestines, and relieving fullness. However, the effects of SM on intestine have rarely been done to date.
Aim Of The Study: To investigate the contraction effect of SM on isolated rat ileum and its mechanisms involved.
Introduction: Biliary tract infection is associated with high mortality. This study investigated the effect of glucocorticoid pretreatment on lipopolysaccharide (LPS)-induced cholangitis.
Methods: Rats undergoing either sham operation or ligation of the extrahepatic bile duct (BDL) for 2 weeks were randomly assigned to receive intravenous injections of dexamethasone (DX) or normal saline (NS) prior to infusing LPS into the biliary tract.
Aim: Biliary intervention may augment chemokine expression and inflammatory cell infiltration and aggravates liver injury in cholestatic rats. We tested the efficacy of glucocorticoid pretreatment to prevent the complications.
Methods: A model of biliary intervention was established in rats without (sham) or with bile duct ligation (BDL).
Background: Intervention of the biliary system is frequently done in patients with obstructive jaundice and is associated with significant morbidity and mortality. The pathogenesis is unknown.
Materials And Methods: A rat model of bile duct ligation (BDL) for 2 weeks was established in which biliary intervention was feasible by injection of normal saline through an indwelling catheter in the bile ducts.
