In this research study, the effect of baclofen (GABAB receptor agonist) on mean concentration of growth hormone, thyroxine, and triiodothyronine was examined. For this purpose, twelve Holstein Cows were divided into four groups. Then, each cow received daily injection of 25, 50, 75, and l00 mg/kg of baclofen for a period of four days. Blood samples were daily collected at one time point for eig...

Blood was taken from women in each trimester of pregnancy at routine antenatal visits. Further samples were collected from an age matched control group of euthyroid women taking no medication. Free triiodothyronine and free thyroxine concentrations were measured by direct radioimmunoassay (Amerlex Kit methods, Amersham International, Amersham, Buckinghamshire).2 These free hormone assays use th...

BACKGROUND Patients with hypothyroidism are usually treated with thyroxine (levothyroxine) only, although both thyroxine and triiodothyronine are secreted by the normal thyroid gland. Whether thyroid secretion of triiodothyronine is physiologically important is unknown. METHODS We compared the effects of thyroxine alone with those of thyroxine plus triiodothyronine (liothyronine) in 33 patien...

In order to investigate the effect of 3,5,3'L-triiodothyronine (T3) administration on thyroid hormone concentrations in serum, thyroxine (T4), T3, 3,3',5'L-triiodothyronine (reverse T3, rT3) and thyroid stimulating hormone (TSH) concentrations in serum were determined before and after T3 administration in 10 hypothyroid patients maintained on constant doses of T4. Ten hypothyroid patients given...

We report on two substance misusers with depression resistant to tricyclic antidepressant treatment who responded to triiodothyronine augmentation. The management of resistant depression, augmentation strategies with particular reference to triiodothyronine, and the possible mechanism of action of triiodothyronine are discussed.

Results are summarized for a scientific project devoted to the comparison of four atmospheric radiative transfer codes incorporated into different satellite data processing algorithms, namely, 6SV1.1 (second simulation of a satellite signal in the solar spectrum, vector, version 1.1), RT3 (radiative transfer), MODTRAN (moderate resolution atmospheric transmittance and radiance code), and SHARM ...

ghrelin increases food intakes and body weight. bombesin decreases food intakes and inhibits the stimulatory effect of ghrelin on food intakes. thyroid hormones have a crucial role in the regulation of body weight and yet the effect of bombesin on thyroid axis activity is not fully clear. therefore, the goal of this study was to determine the effect of different doses of ghrelin or bombesin on ...

Physical activity and sedentary behavior are central components of lifetime weight control; however, our understanding of dimensions of these behaviors in childhood is limited. This study investigated free-living activity pattern characteristics and the individual variability of these characteristics in 84 lean and obese Chinese children (7-9 y) during the school day and over the weekend. Activ...
