I N PHEOCHROMOCYTOMA, 3-methoxy-4-hydroxy-rnandelic acid (VMA), a metabolite of epinephrine and norepinephrine, is excreted in urine in abnormally large quantities. Qitlow et al. (1) have developed a semi quantitative screening method for VMA that we have found to be useful and reliable. The procedure is particularly welcome because it permits screening of a large number of urines from hyperten...

Electrochemical behaviors of methocarbamol (MET) at the bare carbon paste electrode (CPE), acetylene black (AB) modified carbon paste electrode (AB/CPE), an ionic liquid 1-Benzyl-3Methylimidazole hexafluorophosphate ([BnMIM]PF6) modified carbon paste electrode ([BnMIM]PF6/ CPE) and AB-[BnMIM]PF6 modified carbon paste electrode (AB-[BnMIM]PF6/CPE) in PBS (pH = 6.8) were investigated by cyclic vo...

A 17-month-old male King Charles cavalier was presented with acute onset of generalized body tremors, facial twitching and salivation after being exposed to 2 different classes of compounds of the pyrethrins/pyrethroids group as well as to imidacloprid. Bifenthrin toxicity was confirmed by gas chromatography mass spectrometry. Pyrethroid toxicosis in dogs is to the best of our knowledge rarely ...
