Double-blind, placebo-controlled study of the efficacy of Nandrolone laurate in the treatment of dobermanns with subclinical hepatitis
Vet Rec 2005 Sep 10;157(11):313.PMID:16155239DOI:10.1136/vr.157.11.313.
Twenty-one three-year-old dobermanns with subclinical hepatitis were treated with Nandrolone laurate or a placebo in a double-blind trial. The dogs were scored clinically before and after four months of treatment and they were evaluated by clinical biochemistry and liver biopsies. After the treatment no significant differences were observed between the two groups in any of the clinical biochemistry values; eight of the 21 dogs had no histological evidence of hepatitis and five other dogs had improved, but there was no significant difference between the responses of the two groups.
Monitoring the endogenous steroid profile disruption in urine and blood upon nandrolone administration: An efficient and innovative strategy to screen for nandrolone abuse in entire male horses
Drug Test Anal 2014 Apr;6(4):376-88.PMID:23949888DOI:10.1002/dta.1520.
Nandrolone (17β-hydroxy-4-estren-3-one) is amongst the most misused endogenous steroid hormones in entire male horses. The detection of such a substance is challenging with regard to its endogenous presence. The current international threshold level for nandrolone misuse is based on the urinary concentration ratio of 5α-estrane-3β,17α-diol (EAD) to 5(10)-estrene-3β,17α-diol (EED). This ratio, however, can be influenced by a number of factors due to existing intra- and inter-variability standing, respectively, for the variation occurring in endogenous steroids concentration levels in a single subject and the variation in those same concentration levels observed between different subjects. Targeting an efficient detection of nandrolone misuse in entire male horses, an analytical strategy was set up in order to profile a group of endogenous steroids in nandrolone-treated and non-treated equines. Experiment plasma and urine samples were steadily collected over more than three months from a stallion administered with Nandrolone laurate (1 mg/kg). Control plasma and urine samples were collected monthly from seven non-treated stallions over a one-year period. A large panel of steroids of interest (n = 23) were extracted from equine urine and plasma samples using a C18 cartridge. Following a methanolysis step, liquid-liquid and solid-phase extractions purifications were performed before derivatization and analysis on gas chromatography-tandem mass spectrometry (GC-MS/MS) for quantification. Statistical processing of the collected data permitted to establish statistical models capable of discriminating control samples from those collected during the three months following administration. Furthermore, these statistical models succeeded in predicting the compliance status of additional samples collected from racing horses.
Effects of nandrolone treatment on recovery in horses after strenuous physical exercise
J Vet Med A Physiol Pathol Clin Med 2001 Aug;48(6):343-52.PMID:11554492DOI:10.1046/j.1439-0442.2001.00368.x.
To test the effect of nandrolone on their recovery, six adult half-bred riding horses performed a competition exercise test (CET) and a standardized exercise test (SET) on consecutive days before and after a 2-week treatment with the anabolic steroid Nandrolone laurate. Blood samples were collected during and between these tests for the determination of red cell volume and concentrations of blood lactate, plasma glucose, non-esterified fatty acids, glycerol, triglycrides, erythropoietin, cortisol, insulin, and glucagon. Muscle biopsy specimens were taken immediately after the CET and before the SET for analysis of glycogen content, citrate synthase, and 3-hydroxyacyl CoA dehvdrogenase activity. Nandrolone administration increased the rate of muscle glycogen repletion after exercise, an increase that may be explained by increased glucose output by the liver, higher plasma insulin concentration, and increased insulin-independent glucose transport, but not by better availability of lipid fuels during recovery.
Ultra high performance liquid chromatography/tandem mass spectrometry based identification of steroid esters in serum and plasma: an efficient strategy to detect natural steroids abuse in breeding and racing animals
J Chromatogr A 2013 Apr 5;1284:126-40.PMID:23484650DOI:10.1016/j.chroma.2013.02.010.
During last decades, the use of natural steroids in racing and food producing animals for doping purposes has been flourishing. The endogenous or exogenous origin of these naturally occurring steroids has since remained a challenge for the different anti-doping laboratories. The administration of these substances to animals is usually made through an intra-muscular pathway with the steroid under its ester form for a higher bioavailability and a longer lasting effect. Detecting these steroid esters would provide an unequivocal proof of an exogenous administration of the considered naturally occurring steroids. A quick analytical method able to detect at trace level (below 50 pg/mL) a large panel of more than 20 steroid esters in serum and plasma potentially used for doping purposes in bovine and equine has been developed. Following a pre-treatment step, the sample is submitted to a solid phase extraction (SPE) before analysis with UPLC-MS/MS. The analytical method's efficiency has been probed through three different in vivo experiments involving testosterone propionate intra-muscular administration to three heifers, 17-estradiol benzoate intra-muscular administration to a bull and a heifer and Nandrolone laurate intra-muscular administration to a stallion. The results enabled detecting the injected testosterone propionate and 17-estradiol benzoate 2 and 17 days, respectively, post-administration in bovine and Nandrolone laurate up to 14 days post-administration in equine. The corresponding elimination profiles in bovine serum and equine plasma have been established. The first bovine experiment exhibited a maximal testosterone propionate concentration of 400 pg/mL in one of the three heifer serum within 5h post-administration. The second bovine experiment reported a maximal 17-estradiol benzoate concentration of 480 pg/mL in the same matrix recorded 9 days after its administration. The last equine experiment resulted in a maximal Nandrolone laurate concentration of 440 pg/mL in horse plasma 24h after administration.
Proposed mechanisms for the anabolic steroid-induced increase in myocardial susceptibility to ischaemia/reperfusion injury
Cardiovasc J S Afr 2005 Jan-Feb;16(1):21-8.PMID:15778771doi
Androgenic anabolic steroids (AAS) are often used by athletes to enhance athletic performance but are strongly associated with detrimental cardiovascular effects including sudden cardiac death. Hypothesis: AAS use increases myocardial susceptibility to ischaemia/reperfusion injury. Methods: Rats were trained (swimming) with or without intramuscular injection of Nandrolone laurate (0.375 mg/kg). Untrained rats with or without nandrolone served as controls. Hearts were mounted on the Langendorff perfusion apparatus and mechanical function was measured before and after 20-min normothermic global ischaemia. Myocardial tissue samples were collected for determination of tissue cyclic nucleotide and TNFalpha concentrations. Results: Anabolic steroids decreased the rate pressure product (RPP) of the exercise-trained rat heart [34 582 +/- 1 778 mmHg/min vs 28 868 +/- 2 446 mmHg/min for exercise-trained steroid-treated hearts (p < 0.05)]. Reperfusion RPP was lower in both the sedentary, and the exercise-trained, steroid-treated hearts than in their concurrent vehicle-treated controls (18 276 +/- 2 026 mmHg/min vs 12 018 +/- 1 725 mmHg/min for sedentary steroid-treated hearts and, 21 892 +/- 2 912 mmHg vs 12 838 +/- 1 536 mmHg/min for exercise-trained steroid-treated hearts). Myocardial TNFalpha [267.75 +/- 44.25 pg/g vs 190.00 +/- 15.75 pg/g (p < 0.05)] and cAMP concentrations [406.04 +/- 18.41 pmol/g vs 235.6 +/- 43.26 pmol/g (p < 0.05)] were elevated in the steroid-treated hearts when compared with their untreated counterparts. Conclusions: Supraphysiological doses of anabolic steroids, whether taken during exercise training or under sedentary conditions increase myocardial susceptibility to ischaemia/reperfusion injury in our model. This increased susceptibility may be related to steroid-induced increases in the pre-ischaemic myocardial cAMP concentrations and/or increases in both pre-ischaemic and reperfusion TNFalpha concentrations.
