A cytoplasmic progestin receptor has been characterized in the brain of castrated ring doves using an in-vitro assay that measures the binding of a synthetic progestin, [3H]17 alpha,21-dimethyl-19-nor-pregna-4,9-diene-3,20-dione(promegestone; R5020). The affinity of the receptor was similar in both the hyperstriatum and the hypothalamus (Kd approximately equal to 4 X 10(-10) mol/l). Its concentration was higher in the anterior hypothalamus-preoptic area (63 +/- 4 fmol/mg (S.E.M.) protein) than in other brain regions (posterior hypothalamus, 33 +/- 5; hyperstriatum, 28 +/- 3; midbrain, 17 +/- 4 fmol/mg protein; n = 7). Progesterone and R5020 competed well for binding but oestradiol and 5 beta-dihydrotestosterone did not. Corticosterone and, to a lesser extent, testosterone and 5 alpha-dihydrotestosterone completed for binding but much higher concentrations were required than for progestins. Injections of testosterone (200 micrograms testosterone propionate daily for 7 days) significantly increased the concentration of progestin receptors in the anterior and posterior hypothalamus without having any significant effect on other brain areas. Shorter treatment, lasting for 2 days, with testosterone propionate (200 micrograms daily), 5 alpha-dihydrotestosterone (200 micrograms daily) or oestradiol benzoate (50 micrograms daily) did not always cause this increase but seven injections of oestradiol benzoate (50 micrograms daily for 7 days) were even more effective than seven injections of testosterone propionate (200 micrograms daily for 7 days). These data suggested that the sensitivity to progesterone of the brain of the bird changes as a consequence of increases in the level of testosterone in the circulation. [less ▲]

Numerous studies have examined the risk of breast cancer in patients with postmenopausal hormone substitution. Most of these studies are retrospective, and a few recent studies are prospective. The observed results present with weak variations from baseline and major heterogeneity. Some studies highlight a slightly increased relative risk of breast cancer. A reanalysis of 51 studies demonstrates a relative risk of 1.35 for developing breast cancer during hormone substitution, with a 2.3% increased risk per year of use. Recently, the results of the WHI study have shown a slight increase of some risks of disease, including breast cancer (relative risk, 1.26). These results have induced the interruption of one of the 3 arms of the study (that of the patients treated with an estrogen-progestin combination), and have provoked a new discussion about the benefits and risks associated with hormone substitution. These facts have been largely related and commented in the general press. In this article, we review the important studies concerning this topic. [less ▲]

This review describes the clinical usefulness of transdermal hormone replacement therapy. This route of administration is particularly important in women with hypertriglyceridemia, in hypertensive postmenopausal women, in women who smoke or have an increased risk of biliary or liver disorder, for those who display a reduced glucose tolerance or in women who are at risk of thrombotic disorders. The avoidance of the "first passage effect" is ensured by the transdermal application of estrogen and probably explains the superiority of this route of steroid administration. [less ▲]

Reasons for performing study: Equine motor neuron disease (EMND) was diagnosed in 3 horses maintained on lush, grass-based pasture. This contrasted with North American studies which identified limited or no access to green herbage as an important risk factor for EMND. Hypothesis: Grazing horses that have an apparently adequate intake of pasture herbage to meet normal equine vitamin E requirements can develop EMND. Methods: Owners of 32 European horses diagnosed with EMND completed a questionnaire regarding intrinsic, managemental, nutritional and environmental factors that could potentially be risk factors for EMND, and also regarding clinical signs, treatments and case outcome. Plasma/serum vitamin E data for these horses were supplied by the veterinarians. No control population was studied. Results: Thirteen of 32 horses (termed the 'grazing' group) had part- or full-time access to grass-based pasture at the onset of EMND (median duration at pasture 12 h/day, range 3-24 h). Five of these horses were at pasture for at least 23.5 h/day at the onset of EMND, 2 of which were at pasture for at least 23.5 h/day throughout the year. Despite grazing, all these horses had a low vitamin E status. The remaining 19 horses resembled those cases reported from North America, in that they had no or limited access to pasture. Conclusions and potential relevance: A diagnosis of EMND should not be discounted on the basis that a horse has access, even full-time, to lush grass-based pasture. Inadequate vitamin E intake was probably not the sole cause of either the EMND or the low vitamin E status in the grazing horses; the latter was probably the result of abnormal bioavailability or excessive utilisation of vitamin E.

Introduction: For the sound equine forelimb, ground reaction force (GRF) peaks to ~0.8-1 BodyWeight (BW) during the trot (4m/s). Little work investigates the effect of different horsehoeing styles, directly on the limb GRF distribution and indirectly on the equine digit comfort during movement. This study investigates GRF distribution after application of different aluminium horseshoeing styles during movement. Methods: Two horses (H1,H2; mean 575kg) were used. However H2 had an old healed flexor tendons lesion, the horses were judged to be sound on locomotor examination (without lameness). According to the rules that respect the foot biomechanical balance, they were trimmed and shod with a non-broken foot-pastern axis. On the day of the tests, they were led on a treadmill at a trot (4m/s). Kinetics were collected, using a F-Scan system, during 3 following sessions : to both forehooves after application of classic roller, eggbarr and equi+ horseshoes. For each session, data from 3 strides for each left forelimb of each horse were averaged and kinetics (GRF) were obtained. Results: For the classic roller, eggbarr and equi+ horseshoes, GRF peaked respectively to 0.57+-0.006;0.36+-0.005;0.83+-0.009BW for H1 and 0.61+-0.007;0.84+-0.007;0.51+-0.009BW for H2. Theses horseshoes loading differences show a dynamic load transfer from the forelimbs to the hindlimbs, that is the result of a subclinic (without lameness) equine digit discomfort during movement. Conclusions: Subclinic equine digit discomfort after application of horshoes has been detected using the F-Scan system during movement. These results confirm the interest of the equi+ horseshoes on horses without flexor tendon lesion. [less ▲]
