Testosterone: a Metabolic Hormone in Health and Disease
D M KELLY and T H JONES Testosterone metabolic hormone 217:3 R25–R45 Review Testosterone: a metabolic hormone in health and disease Daniel M Kelly1 and T Hugh Jones1,2 Correspondence should be addressed to 1Department of Human Metabolism, Medical School, The University of Sheffield, Sheffield S10 2RX, UK 2Robert T H Jones Hague Centre for Diabetes and Endocrinology, Barnsley Hospital NHS Foundation Trust, Gawber Road, Barnsley S75 Email 2EP, UK [email protected] Abstract Testosterone is a hormone that plays a key role in carbohydrate, fat and protein metabolism. Key Words It has been known for some time that testosterone has a major influence on body fat " metabolism composition and muscle mass in the male. Testosterone deficiency is associated with an " testosterone increased fat mass (in particular central adiposity), reduced insulin sensitivity, impaired " type 2 diabetes glucose tolerance, elevated triglycerides and cholesterol and low HDL-cholesterol. All these " metabolic syndrome factors are found in the metabolic syndrome (MetS) and type 2 diabetes, contributing to cardiovascular risk. Clinical trials demonstrate that testosterone replacement therapy improves the insulin resistance found in these conditions as well as glycaemic control and also reduces body fat mass, in particular truncal adiposity, cholesterol and triglycerides. The mechanisms by which testosterone acts on pathways to control metabolism are not fully clear. There is, however, an increasing body of evidence from animal, cell and clinical studies that testosterone at the molecular level controls the expression of important regulatory proteins involved in Journal of Endocrinology glycolysis, glycogen synthesis and lipid and cholesterol metabolism. The effects of testosterone differ in the major tissues involved in insulin action, which include liver, muscle and fat, suggesting a complex regulatory influence on metabolism. -

Precursor Ion Scanning for the Detection of New Steroid Markers
“Precursor ion scanning for the detection of new steroid markers. Routine application for the open screening of anabolic steroids and evaluation of population factors in the detectability of these markers” P. Mendoza, F. Delbeke, K. Deventer, P. Meuleman, J. Segura, R. Ventura (Fondacio IMIM, Barcelona, Spain) K. Deventer, P. Van Eenoo, O. Pozo Mendoza (Ghent University, Belgium) PROJECT REVIEW This project aims at four goals: A. Interpretation and evaluation of precursor ion scanning chromatograms (urine profile recognition) In the field of anti-doping control, chromatograms from target steroid-analysis are generally evaluated and interpreted visually by the analyst which is trained for this purpose. A similar approach will be adopted for evaluating the precursor scanning chromatograms. To get acquainted with the chromatograms, around 50 blank samples will be analysed. In a second step precursor ion scan chromatograms obtained from controlled administration studies (e.g. methyltestosterone, methanedienone,…) and from adverse analytical findings from routine target screening will also be investigated to get acquainted with positive samples. The applicability of instrument software for this purpose will be evaluated. B. Application to real samples Urine-samples will be analysed. These samples will include all out of competition samples and both out of competition samples and in competition samples C. Study of the influence of different population factors in the detectability of different markers for several anabolic steroids A single dose of the previously studied steroids (stanozolol and methyltestosterone) will be administered to six volunteers belonging to different population groups. Urine will be collected for three weeks and a method including all feasible markers will be applied. -
Oxandrin (Oxandrolone Tablets, USP) DESCRIPTION Oxandrin Oral Tablets Contain Either 2.5Mg Or 10Mg of the Anabolic Steroid Oxandrolone
BTG PHARMACEUTICALS Oxandrin (oxandrolone tablets, USP) DESCRIPTION Oxandrin oral tablets contain either 2.5mg or 10mg of the anabolic steroid oxandrolone. Oxandrolone is 17B-hydroxy-17a-methyl-2- oxa-5a-androstan-3-one with the following structural formula. Inactive ingredients include cornstarch, lactose, magnesium stearate, and hydroxypropyl methyl-cellulose. CLINICAL PHARMACOLOGY Anabolic steroids are synthetic derivatives of testosterone. Certain clinical effects and adverse reactions demonstrate the androgenic properties of this class of drug. Complete dissociation of anabolic and androgenic effects has not been achieved. The actions of anabolic steroids are therefore similar to those of male sex hormones with the possibility of causing serious disturbances of growth and sexual development if given to young children. Anabolic steroids suppress the gonadotropic functions of the pituitary and may exert a direct effect upon the testes. During exogenous administration of anabolic androgens, endogenous testosterone release is inhibited through inhibition of pituitary luteinizing hormore (LH). At large doses, spermatogenesis may be suppressed through feedback inhibition of pituitary follicle-stimulating hormone(FSH). Anabolic steroids have been reported to increase low-density lipoproteins and decrease high-density lipoproteins. These levels revert to normal on discontinuation of treatment. INDICATIONS AND USAGE Oxandrin is indicated as adjunctive therapy to promote weight gain after weight loss following extensive surgery, chronic infections, or severe trauma and in some patients who without definite pathophysiologic reasons fail to gain or to maintain normal weight, to offset the protein catabolism associated with prolonged administration of corticosteroids, and for the relief of the bone pain frequently accompanying osteoporosis (See DOSAGE AND ADMINISTRATION). DRUG ABUSE AND DEPENDENCE Oxandrolone is classified as a controlled substance under the Anabolic Steroids Control Act of 1990 and has been assigned to Schedule III (non-narcotic). -

BERTRAND, Ph.D. Centre de Recherches en Sciences de la Sante, Institut National de la Recherche Scientifique, Centre Hospitalier Louis-H. Lafontaine, Montrdal, Quebec, Canada ABSTRACT Recently developped radioimmunoassays (RIA) for the analysis of anabolic steroids and their metabolites in biological fluids were tested for cross-reactivity with other types of steroids. Results show that the degree of desirable cross-reactivity within the two classes of orally active anabolic steroids vary widely and that the antiserum for 19-Nortestosterone (the active principle of intramuscular, preparations) has a very high degree of undesirable cross- reactivity with components of oral contraceptives. Single and multiple dose studies in human volunteers demonstrate that the detection level and degree of retrospectivity are likewise variable but that the test easily detects most anabolic steroids during treatment. At the present time, the combination of the three antisera for the assay of a sample appears to be a relatively rapid and economic method for screening large numbers of samples in situations where doping control of anabolic steroids is required. The importance of utilizing physico-chemical means for identification of RIA potential positives is emphasized.
