1. The pharmacokinetics of monensin, including half-life, apparent volume of distribution, total body clearance, systemic bioavailability and tissue residues were determined in broiler chickens. The drug was given by intracrop and intravenous routes in a single dose of 40 mg/kg body weight. 2. Following intravenous injection the kinetic disposition of(More)
1. The effects of nitrates and nitrites on growth, erythrocytic count, liver and kidney functions, humoral and cell mediated immune responses in cockerels were investigated. 2. Sodium nitrate (4.2 g/kg diet) and sodium nitrite (1.7 g/kg) retarded growth, caused methaemoglobinaemia and changes in erythrocytic count, serum concentrations of glutamic-pyruvic(More)
Cefotaxime was once administered in goats via intravenous, intramuscular and subcutaneous routes for determination of blood and urine concentration, kinetic behaviour and bioavailability. Following a single intravenous injection, the blood concentration-time curve indicated two compartments open model, with an elimination half-life value (t1/2 beta) of(More)
Salinomycin was administered to chickens orally and intravenously to determine blood concentration, kinetic behaviour, bioavailability and tissue residues. The drug was given by intracrop and intravenous routes in a single dose of 20 mg kg-1 body-weight. The highest serum concentrations of salinomycin were reached half an hour after oral dosage with an(More)
In 12 experiments on 6 mongrel dogs, furosemide was given both orally and i.v. in a dose of 20mg/kg. Following i.v. injection, the blood concentration curve followed an open one-compartment model. The elimination half-lives after both oral and i.v. routes were nearly similar, i.e. 1.42 +10.13 and 1.13 +0.06 hours respectively. The apparent volume of(More)
Platelet-activating factor (PAF), an 1-0-alkyl-2-acetyl-sn-glycero-3-phosphocholine, plays an important role in tissue inflammation and ischemia. Previous results from our laboratory have shown that PAF is synthesized in the cornea after injury and that PAF antagonists reduced inflammation in an experimental model of anterior uveitis. This study was(More)
Fetotoxic effects induced by three anticoccidial drugs: robenidine, salinomycin and arprinocid were elucidated in the chicken. Different doses of these drugs were inoculated in groups of embryonated chicken eggs by the yolk sac route. After inoculation, candling of the eggs was performed daily and embryonic or fetal mortalities were recorded. At 19 days(More)
The pharmacokinetic aspects of florfenicol (FLO) were investigated via intravenous (I.V.) and intramuscular (I.M.) injections in five goats at a dose of 20 mg kg(-1) b.wt. Animals were pre-treated with albendazole orally in a dose of 2.5 mg kg(-1) b.wt, ivermectin or rafoxanide subcutaneously in a dose 0.2 and 7.5 mg kg(-1) b.wt, respectively. Florfenicol(More)
