Plasma aldosterone concentration can increase in anephric man during hemodialysis despite the lack of kidneys to produce renin. Because the metabolic clearance rate of aldosterone does not change during hemodialysis, aldosterone secretion must increase in response to sodium depletion, volume depletion, or both. This study was designed to determine the relative influence of sodium and volume dep...

The aim of this study was to evaluate pharmacokinetic profiles of florfenicol after a single dose of intravenous (5.00 mg kg-1 body weight) and oral (40.00 mg kg-1 body weight) administrations in common carp (Cyprinus carpio). The residue depletion of florfenicol was also investigated after oral administration (10.00 mg kg-1 body weight) and bath treatm...

the bioavailability of two dipyridamol tablet formulations of (dipyridamole from tolidaru and persantin from boehringer) was compared in 14 healthy male volunteers who received a single dose of 25 mg of the test (t) and the reference (r) products in a randomized balanced 2-way crossover design. plasma samples were obtained over a 16 h interval and dipyridamole concentrations determined by hplc ...

Adjustment of phenytoin dosage in patients is very difficult due to its nonlinear metabolism and patient to patient variation in its kinetics. It has been recommended that the dosage of phenytoin should be adjusted according to its plasma concentration and requirements of the patients. Therefore, the present study was carried out to identify the various factors which may influence the plas...
