The effect of the diuretic spironolactone (SL) on expression and function of intestinal P-glycoprotein (P-gp), as well as its impact on intestinal absorption of digoxin, was explored. Rats were treated with daily doses of 200 micromol/kg b.wt. of SL intraperitoneally for 3 consecutive days. The small intestine was divided into four equal segments of(More)
We evaluated the effect of acetaminophen (APAP), given as a single, 1g/kg body weight dose, on expression and activity of rat liver multidrug resistance-associated protein 2 (Mrp2) and P-glycoprotein (P-gp), two major canalicular drug transporters. The studies were performed 24h after administration of the drug. APAP induced an increase in plasma membrane(More)
This paper presents a study on interference in microcellular networks with reuse patterns based on a square grid. The performance of the system is assessed by means of the carrier-to-interference ( U I ) ratio for a series of situations such as: the worst case condition, mobiles randomly positioned, and channel activity according to a given trafJic(More)
Excretion of lipophilic cationic toxic compounds from the interior of the hepatocyte to the bile is mediated by P-Glycoprotein. It is an integral protein located in the bile canaliculi. The present work study the hepatic expression of P-Glycoprotein in different models of experimental liver disease: Acute paracetamol intoxication, extrahepatic cholestasis(More)
