Biliary and renal excretions of cefpiramide in Eisai hyperbilirubinemic rats.
Eisai hyperbilirubinemic mutant rats (EHBRs) with conjugated hyperbilirubinemia were recently derived from Sprague-Dawley rats (SDRs). The pharmacokinetic characteristics of the beta-lactam antibiotic cefpiramide (CPM), which is mainly excreted into bile, were investigated in 10- and 20-week-old EHBRs and were compared with those in 20-week-old healthy SDRs. The pharmacokinetic parameters of CP...
متن کاملHepatic uptake of bromosulfophthalein-glutathione in perfused Eisai hyperbilirubinemic mutant rat liver: a multiple-indicator dilution study.
The hepatocellular uptake of the glutathione conjugate of bromosulfophthalein (BSPGSH) was examined in Eisai hyperbilirubinemic rats (EHBR; originating from Sprague-Dawley rats), which lacked the ATP-dependent canalicular transport for non-bile acid organic anions, a trend common to other mutant rat strains (TR- and GY, originating from Wistar rats). Single-pass perfused rat liver experiments w...
متن کاملHepatic expression of multidrug resistance-associated protein-like proteins maintained in eisai hyperbilirubinemic rats.
The biliary excretion of several organic anions is mediated by the canalicular multispecific organic anion transporter (cMOAT), which is hereditarily defective in mutant rats such as Eisai hyperbilirubinemic rats (EHBR). In addition, using a kinetic study with isolated canalicular membrane vesicles, we recently suggested the presence of ATP-dependent organic anion transporter(s) other than cMOA...
متن کاملANTICONVULSANT THERAPY-INDUCED ALTERATIONS IN CALCIUM HOMEOSTASIS
35 epileptic patients, aged 10 to 58 years (mean 23), who were taking anticonvulsant drugs were studied. The patients exhibited a 34% reduction in serum calcium levels, a 41 % increase in serum alkaline phosphatase activity and a slight but insignificant decrease in serum phosphate, compared to untreated controls. These changes appear to be related to the anticonvulsant drug taken, in the ...
متن کاملHepatobiliary excretion of acetaminophen glutathione conjugate and its derivatives in transport-deficient (TR-) hyperbilirubinemic rats.
The involvement of the canalicular multidrug resistance protein 2 (Mrp2) in the hepatobiliary excretion of acetaminophen (APAP)-glutathione (GSH) conjugate and its derivatives was investigated using transport-deficient (TR- rats. Although no differences in the biliary concentration of APAP itself were detected between normal Wistar and TR- rats, significant differences in the biliary dispositio...
