gamma-aminobutyric acid (gaba) is an important inhibitory transmitter in central nervous system and is involved in pathophysiology of epilepsy. pentylenete-trazole (ptz), a convulsant agent, partly acts via anion channel of gabaa receptor. ivermectin, an antiparasitic agent and a gabaa agonist, has anticonvulsant effect in animal seizure models. cholestasis increases the threshold of ptz-induce...
AIM To analyze time intervals of inflammation and regeneration in a cholestatic rat liver model. METHODS In 36 Lewis rats, divided into six groups of 6 animals (postoperative observation periods: 1, 2, 3, 4, 6, 8 wk), the main bile duct was ligated with two ligatures and observed for the periods mentioned above. For laboratory evaluation, cholestasis parameters (bilirubin, γ-GT), liver cell p...
INTRODUCTION Drug-induced cholestasis, intrahepatic cholestasis of pregnancy and viral hepatitis are acquired forms of liver disease. Cholestasis is a pathophysiologic state with impaired bile formation and subsequent accumulation of bile salts in hepatocytes. The bile salt export pump (BSEP) (ABCB11) is the key export system for bile salts from hepatocytes. AREAS COVERED This article provide...
One hundred and twenty-four infants admitted to hospitals in Norway between 1955 and 1974 during the first 3 months of life with cholestatic jaundice were studied retrospectively. Sixty-four infants had had extrahepatic atresia of the biliary tree and 60 had had intrahepatic cholestasis. This gives an incidence of about 1:9000 live births for cholestasis. In 4 of the 64 infants with extra-hepat...
To investigate the protective effect of glutamine (Gln) against obstructive cholestasis in association with farnesoid X receptor (FXR) activation, an obstructive cholestasis model was established in male Sprague-Dawley rats by bile duct ligation (BDL). Serum biomarkers and hematoxylin plus eosin staining were used to identify the degree of hepatic injury in the rats with obstructive cholestasis...
Primary biliary cirrhosis is a chronic liver disease of unknown etiology, characterized by inflammation and destruction of the intrahepatic biliary ducts, resulting in chronic cholestasis and eventually cirrhosis. The main clinical manifestations consists of pruritus, jaundice, xanthomas, and the consequences of intestinal malabsorption, including vitamin deficiencies and osteodystrophy. Treatm...
Cholestasis is a serious manifestation of liver diseases with limited therapies. Rhubarb, a widely used herbal medicine, has been frequently used at a relatively large dose for treating cholestasis. However, whether large doses are optimal and the therapeutic mechanism remain unclear. To explore these questions, the anti-cholestatic effect of five doses of rhubarb (0.21, 0.66, 2.10, 6.60, and 2...
The plasma clearance of pancuronium in patients with extrahepatic cholestasis was 16% lower than in a control group (1.47 +/- 0.11 ml min-1 kg-1 v. 1.76 +/- 0.21 ml min-1 kg-1), but the difference was not significant. A significant increase in the elimination half-life T 1/2 beta of pancuronium (from 141 to 224 min) and a significant increase in the volume of the peripheral compartment (V2) was...
BACKGROUND Following bile duct ligation (BDL) endogenous opioids accumulate in plasma and play a role in the pathophysiology and manifestation of cholestasis. Evidence of centrally mediated induction of liver injury by exogenous opioid agonist administration, prompts the question of whether opioid receptor blockade by naltrexone can affect cholestasis-induced liver injury. METHODS Cholestasis...
BACKGROUND Cognitive functions are impaired in patients with liver disease. Bile duct ligation causes cholestasis that impairs liver function. This study investigated the impact of cholestasis progression on the acquisition and retention times in the passive avoidance test and on the locomotor activity of rats. METHODS Cholestasis was induced in male Wistar rats by ligating the main bile duct...
