The abuse of doping agents in competing body builders in Flanders (1988-1993).
Analytical findings of unannounced doping control in body builders in Flanders during 1988-1993 are reported and there was no fall in drug abuse over this period and steroids were taken even by body builders associated with an organisation against the use of anabolic steroids. Expand
Detection and metabolism of fencamfamine and the influence of acetazolamide on its urinary excretion.
No changes occurred in urinary fencamfamine or metabolite concentrations during storage of urine at -18 degrees for 6 weeks and gas-chromatographic (g.l.c.) method with electron-capture (e.c) detection is described for the simultaneous quantitative determination of nanogram concentrations of 2-ethylamino-3-phenyl-norbornane in urine.

Screening for 18 diuretics and probenecid in doping analysis by liquid chromatography-tandem mass spectrometry.
The fast and selective liquid chromatography-tandem mass spectrometric method was applied to detect diuretics after the oral administration of several drugs including hydrochlorothiazide, bumetanide, spironolactone, furosemide, amiloride, triamterene, chlortalidone and epithizide. Expand
Caffeine: use and abuse in sports.
A "maximum level of caffeine" of 15 micrograms X ml-1 in urine for sporting competitions is proposed based on results for sportsmen and the younger categories (debutant and junior). Expand
The influence of diuretics on the excretion and metabolism of doping agents: Part VI. Pseudoephedrine
A capillary gas chromatographic method with nitrogen specific detection is presented for measuring pseudoephedrine and its major metabolite norpseudoephedrine in urine after derivatization withExpand
Distribution of caffeine levels in urine in different sports in relation to doping control.
Comparison of those sports with more than 200 samples being analysed demonstrated that caffeine concentrations in urine samples from bodybuilders are significantly higher in comparison to urines taken in the other sports. Expand
ELISA detection of fentanyl in horse urine and plasma.
The prototype of a commercial ELISA test kit designed for fentanyl determination in human urine has been evaluated for screening fentanyl in horse urine and plasma and it is found that the ELISA assay is simple and could be successfully used for quantitative measurements in diluted urine. Expand
Disposition of human drug preparations in the horse. II. Orally administered fencamfamine.
A gas chromatographic method to measure urinary levels of the central nervous system stimulant fencamfamine and some of its metabolites is described and the injudicious use of human doping routine methods for the detection of fencmfamine in equine urine could lead to false negative results. Expand
