Radioimmunoassay technique for detecting urinary excretion products after administration of synthetic anabolic steroids to the horse.

1. Cross-bred and thoroughbred geldings were injected with veterinary doses of various synthetic anabolic steroids. Urines collected sequentially from treated animals were analysed, following solvent extraction, by radioimmunoassay using 19-[3H]nortestosterone and an antibody raised against a 19-nortestosterone immunogen. 2. Urinary excretion of 19-nortestosterone and/or its cross-reacting metabolites was detectable for various times after administration of different nortestosterone esters, as follows: phenylpropionate (400 mg), greater than 14 days; cyclohexylpropionate (100 mg), greather than 10 days; laurate (200 mg) greater than 50 days. After administration of the parent steroid (150 mg) cross-reacting compounds were detectable in urine for ca. 3 days. 3. Urinary excretion of esters of other anabolic steroids cross-reacting with the 19-nortestosterone antibody (e.g. 1-dehydrotestosterone and trienbolone) could also be followed by analysing solvent extracts of urines by the radioimmunoassay. Cross-reacting compounds in urine after administration of 1-dehydrotestosterone undecylenate (250 mg) and trienbolone acetate (75 mg) could be detected for greater than 35 days and greather than 5 days, respectively.

Veterinary aspects of doping.

Doping can improve or impair performance and can be done either deliberately or accidentally. Accidental doping to win is the offence which most concerns the veterinary surgeon. The distinction between legitimate therapy and assisting an unfit horse to win a race by giving it a drug is a fine one. General guidelines are presented for the veterinary surgeon in practice.

A review of drug "clearance times" in racehorses.

A review is presented of published and some unpublished work dealing with aspects of drug clearance from horses. This work includes plasma half-lives and urinary clearance times for specified drugs, as well as a consideration of more general factors likely to influence these values. The review is presented primarily as a guide to the veterinary surgeon in practice, to assist in the drug therapy of horses without contravening the Rules of Racing relating to doping.

Surrogate mother-child relationships.

Many children are raised by a surrogate mother after loss of their biological mother. The process of developing a relationship between the child and surrogate is complicated by the image of the biological parent. Interactional difficulties, highlighted by separation and loss, must be worked through to establish a viable bond.

Recent advances in the field of doping detection.

Patterns of doping in Britain have on the whole changed from the use of CNS stimulants and depressants to therapeutic substances, or to accidental doping by feeding contaminated food or food supplements. Progress in detection and identification is largely a result of improvements in separation and isolation, especially by gas chromatography, together with the introduction of mass spectrometry. Radiommunoassay and high performance liquid chromatography promise to be important techniques in the future, especially in detection of anabolic steroids and corticosteroids.
