چکیده
In total, 240 studies including serum T4, T3, TSH and thyroid uptake at 2 and 24 hrs were performed in 48 Bangladeshi adult individuals (52% female and 48% male). The aim of the present study was to make a correlation between thyroid serum levels and radioiodine thyroid uptake values of same individuals. Serum T4 and T3 were assessed with commercially available radioimmunoassay kits and TSH with a highly sensitive immunoradiometric assay kits (Beijing Atom Hightech Co. Ltd., China). The uptake study was consisted of oral administration of 6 – 10 μCi of 131 I as sodium-iodide. Correlation coefficients (r) were calculated and tested for statistical significance. Radioiodine thyroid uptake values measured in this study show a statistically significant positive correlation with T4 and T3 levels and negative correlation with serum TSH levels. The present results were also compared with the experimental data available in literature and found to be in fairly good agreement.

The pituitary-Thyroid axis of 12 Acromegalic patients was evaluated by measurement of the concentration (Total and free of thyroxine T4, T3 and revers T3 (rT3) and TSH, GH and prolactin before and after in stimulation with TRH. Using an ultrasensitive method of TSH measurement (IRMA) basal serum TSH levels of patients (0.76, 0.07-l.90mlU/L) were found slightly but significantly (P < 0.01), low...

Background: Subclinical hypothyroidism is characterized by normal circulating thyroid hormone levels with super-normal TSH concentrations in absence of clinical manifestations. In majority of subjects, an etiologic factor is often identified. Moreover, therapy with levothyroxine normalizes serum TSH concentration while maintaining normal thyroid hormone concentrations. However, the exact pathop...

This study was designed to evaluate the thyroid and pituitary hormone levels in post-weaning rats whose dams were fed a low-protein diet during suckling (21 days). The dams and pups were divided into 2 groups: a control group fed a diet containing 22% protein that supplies the necessary amount of protein for the rat and is the usual content of protein in most commercial rat chow, and a diet gro...

In order to investigate the effect of different levels of rapeseed meal on performance and content of triiodothyronine (T3), thyroxine (T4) and thyroid stimulating hormone (TSH) in broiler chickens’ blood, 640 1-d-old Ross male broiler chickens were studied through a 4 × 2 factorial arrangement including 4 levels of rapeseed meal (RSM) (0, 5, 10 and 15 percent) and two levels of enzyme (0 and 0...

Inappropriate TSH hypersecretion was diagnosed in a 34 years old woman. Earlier she had been treated by ablative therapy for hyperthyroidism. The present diagnosis was based on elevated basal serum TSH levels despite elevated serum free thyroid hormone level. Her TSH responses to TRH (peak value 240 mu/I) was high. Her albumin and prealbumin levels were normal. The serum TBG level, alpha subuni...
