Effects of Season and Sex on Thyroid Hormone Level in the Blood of Osimi Sheep

Introduction: The purpose of this study was to investigate the changes of serum ACTH and Thyroid hormone level in the acute phase of ICH. Methods: Sixty patients with spontaneous ICH were assessed regarding hormonal changes by measuring ACTH and Thyroid hormone level. The relationships of hormone concentrations to clinical and radiological parameters were evaluated at hospital admission (t0), 5 days (t1) and 10 days (t2). The results were statistically analyzed. Results: ACTH, TSH, Thyroxine, and free Thyroxine were not signiﬁcantly different among the three time periods (P > 0.05), while Triiodothyronine (T3) and free Triiodothyronine (FT3) were signiﬁcantly different (P < 0.05). T3 and FT3 were not signiﬁcantly different among patients with hemorrhage of different locations (P>0.05). There were significant negative correlations between T3 and FT3 with volume of ICH (r=-0.63 and r=-0.25) and there were positive correlations between T3 and FT3 with GCS (r=0.63 and r=0.37) respectively on admission day (p <0.05). Conclusions: Hormonal secretion patterns is associated with the severity of ICH. This is an important index to evaluate the disease severity and prognosis. Keywords: ACTH; ICH; lymphocyte ICH; Thyroid hormone.

The objective assessment of poultry welfare is presently a global problem, which is directly related to poultry products. The investigations on the possibilities for evaluation of the physiological comfort of turkeys by the use of alternative indicators are scarce. The aim of the present study was to determine the reliability of liver weight and thyroid hormone level in male turkeys from Local Bulgarian hybrid as indicators of their welfare. Plasma thyroxine levels were determined by radioimmunoassay method (RIA). The relative liver weights and plasma thyroxine levels of the I-st group turkeys (Local hybrid, reared on the litter) were significantly higher than in the II-nd one (Local hybrid, reared on the slat floor). A correlation between plasma thyroxine levels and plasma corticosterone levels in male turkeys, raised on the litter was established. A close relationship was found between liver weight, plasma thyroxine levels and the status of poultry welfare.

Abstract. The possibility of a relationship between the thyroid hormone level and the peripheral action of catecholamines was examined in 4 normal-weight and 19 obese euthyroid subjects as well as in 27 hyperthyroid subjects by comparing the serum thyroid hormone level and the in vitro effect of catecholamines on lipolysis and cyclic AMP accumulation in adipose tissue incubated with and without isopropyl noradrenaline (ISNA) or noradrenaline (NA). ISNA- and NA-induced rates of lipolysis and cyclic AMP production were significantly correlated with free thyroxine index (r = 0.63–0.74) and with the serum triiodothyronine level (r = 0.83–0.87). The thyroid hormone level was neither correlated with basal rate of lipolysis nor with basal cyclic AMP production (r < 0.2). These results suggest that the magnitude of catecholamine-induced cyclic AMP production by peripheral cells may be regulated by the level of circulating thyroid hormones. The effect of thyroid hormones on lipolysis appears to be specifically linked to the action of catecholamines.
