Hormones are hormones secreted by the thyroid gland and their primary function is to regulate speed of metabolism in many tissues. The releases its into bloodstream response a regulating hormone released pituitary called thyroid-stimulating hormone. It only organ body that has ability synthesize iodine large quantities for use synthesis hormones. consists two lobes, joined together isthmus, loc...

the aim of this study was to show the effect of four feeding regimes on thyroid hormones concentrations, growth performance and food coefficient in rainbow trout applied through 4 treatments and 3 replications in winter 2006. in this research, samples of rainbow trout with an initial mean weight (so) 47.19±0.42 used in each rearing unite. fish were fed twice a day ad libitum as follows: treatme...

background: since the introduction of the first radioimmunoassay, several improvements have been made in the design of immunoassays such as method of antibody production, labeling, automation and detection technology. we performed an analytical evaluation of the new electrochemiluminescent immunoassay (eclia) for serum tsh, ft4 and t3 in the elecsys 2010 immunoassay system and compared the resu...

this study was conducted to investigate the effect of ascites-related physiological and metabolic parameters in broiler chickens fed with different components of bentonite. two hundred and seven days old arian male chicks were allocated into five dietary treatment groups including 1) basal diet (control); 2) basal diet + 1% sulphated sodium bentonite (ssb); 3) basal diet + 1% non-processed sodi...

introduction: muslims fast from dawn to dusk during ramadan. the effects of prolonged food deprivation on endocrine hormones have been studied in healthy adults but no previous study has investigated this effect on children. this study aimed to evaluate the feasible changes in serum level of thyroxin (t3), tetraiodothyronin (t4), thyroid stimulating hormone (tsh) and body composition in pre-men...

thyroid hormones (t3, t4) have marked effect on body metabolism and in controlling osmoregulation activity in fish. the aim of this study was to determine the effect of water salinity changes on thyroid hormones level and thyroid-stimulating hormone (tsh) of grass carp. for this purpose 120 grass carp were divided randomly in to four groups (10 fish in each group and three replicates per treatm...

Background and Aims: 25-hydroxy vitamin D3 is recognized to be an essential element for healthy body; however, its deficiency has been identified as a risk factor for thyroid disease, diabetes mellitus and other autoimmune diseases and infectious diseases. Thyroid disease is common in the general population that its prevalence increases proportional to age. Subjects with poorly controlled diabe...
