Scientists are constantly striving to find new tools to assess their welfare, in order to ameliorate husbandry conditions, leading to a better life and scientific data. Steroid hormones can provide information regarding different behavioral tracts of laboratory animals but their quantification often require stressful sampling procedures. Hair represents a good, less invasive, alternative in such scenario and is also indicative of longer timespan due to hormones’ accumulation. The aim of the work was to quantify steroid hormones in the hair of male laboratory mice and to look for differences imputable to age and housing conditions (pairs VS groups). Age influenced all analysed hormones by increasing testosterone and dehydroepiandrosterone (DHEA) levels and decreasing corticosterone.

In this paper, the content of 5β type steroid, inducing δ-aminolevulinic acid synthetase, was studied by noticing the activities of steroid 5β-reductase, which is the rate limiting enzyme in metabolism of steroid hormones, 3α- and 3β-hydroxysteroid dehydrogenase. For measurement of these activities, 105,000×g supernatant of rat liver was used. The testosterone and ⊿4-androstene-3, 17-dione 5β-reductase activities decreased on either the fourth or eleventh day after either intraperitoneal or subcutaneous administration of mercuric acetate, respe- ctively, and the adrenosterone 5β-reductase activity increased on the eleventh day after the subcutaneous administration of mercuric acetate. These changes mentioned above, however, were not significant. The progesterone and 17α-hydroxy progesterone 5β-reductase activities decreased on either the fourth or eleventh day after either intraperitioneal or subcutaneous administration of mercuric acetate, but there were no significant changes.

    Proceedings of the British Pharmacological Society at http://www.pA2online.org/abstracts/Vol11Issue3abst082P.pdf 5alpha-Tetrahydrocorticosterone: A Novel Topical Anti-inflammatory Agent With Improved Therapeutic Index DE Livingstone, C Sykes, L Hollis, BR Walker, R Andrew. Univeristy of Edinburgh, Edinburgh, UK Topical steroids are the mainstay of treatment of inflammatory skin conditions such as eczema, but their use is limited by negative effects on skin integrity. Furthermore, chronic topical treatment is sometimes associated with systemic effects on metabolic function. There is therefore a need for novel steroid treatments with dissociated anti- inflammatory vs metabolic effects. We have previously identified 5alpha- tetrahydrocorticosterone (5aTHB) as a novel glucocorticoid receptor ligand(1) which displays dissociated effects in vitro(2). The aim here was to determine the anti- inflammatory efficacy of 5aTHB in vivo, along with effects on skin thickness, in comparison with the most commonly used topical steroid, hydrocortisone (HC). Anti-inflammatory efficacy was determined in adult male C57Bl6 mice. Inflammation was stimulated by topical treatment with croton oil to the right ear (300ug in 95:5 ethanol:isopropylmyristate) and swelling assessed at cull after 24 hr by ear weight vs untreated ear. Dose-responses to 5aTHB and hydrocortisone (0-100ug) were determined by co-administration of steroid with croton oil, and IC50 calculated by curve fitting of %maximal inflammation (n=6-12/dose). To ascertain the effect of 5aTHB on skin thickness, 5aTHB or HC (0,25,100,200ug in 95:5 ethanol:isopropylmyristate) was applied to the right ear of mice daily for 4wks (n=6/group). Doses were selected following dose response studies as efficacious (25ug), high therapeutic (100ug) and pharmacological (200ug).
