1. The disposition of radioactivity has been studied in rats and dogs after administration of a new anthelminthic agent, 14C-labelled methyl-5-cyclopropylcarbonyl-2-benzimidazole carbamate (14C-ciclobendazole). 2. An oral dose of 14C-ciclobendazole (4 mg/kg) to rats was rapidly absorbed and about 70% and 20% of the dose was excreted in the faeces and urine,(More)
A major metabolite of ciclobendazole (methyl 5-cyclopropylcarbonyl-2-benzimidazolecarbamate) excreted in the urine, bile, and feces of rats was methyl 5-cyclopropylcarbonyl-6-hydroxy-benzimidazolecarbamate, established by comparison of the proton magnetic resonance and mass spectra with that of the authentic compound. This compound represented 8.2% and 7.1%(More)
1. The metabolic fate of 14C-ximoprofen was compared in rat (2 mg/kg), baboon (2 mg/kg) and human (approx. 0.4 mg/kg). An oral dose was well absorbed in all three species as indicated by urinary excretion of 80%, 86% and 94% dose respectively in 5 days: excreted in the faeces were 14%, 2% and 2% dose respectively. 2. Total 14C in plasma reached peak(More)
The disposition and metabolic fate of [4-14C]coumarin in a 70% aqueous ethanol solution was studied in male Lister Hooded rats after occluded dermal application and in three male volunteers after an exposure designed to simulate that which may be encountered when using an alcohol-based perfumed product. In both cases, the 6-h exposure was 0.02 mg/cm(2)(More)
Starting in the mid-1980s, grammars in the DCG, PATR and LFG formats have been implemented at the University of Constance. Experience has shown that translating a grammar specification into machine interrretable code, e.g., Prolog, is difficult and error-prone. A current attempt to let students and research co-workers formulate and test grammar sketches in(More)
During 5 days following a single oral dose of 3H-11-bromovincamine (40 mg) to two human subjects, means of 55% and 27% of the 3H dose were excreted in the urine and faeces respectively, mainly within 24 and 48 h. Mean plasma concentrations of 3H reached a peak (1900 ng equiv./ml) at 1 h after dosing and declined biphasically with half-lives of 5 h and 11 h(More)
