The dependent tumors exhibited minor chromosomal changes and thyroglobulin antigenicity similar to that of normal rat thyroid. The transitional tumors exhibited moderate chromosomal alterations and practically no thyroglobulin antigenicity. The autonomous tumors exhibited severe chromosomal alteration, numerically and/or structurally, and no detectable immunogenicity related to thyroglobulin. A...

Background: Serum thyroglobulin appears to be a sensitive marker of thyroid dysfunction in endemic goiter. However, its value as an indicator of thyroid status in children after the introduction of iodized salt has not been tested. Objective: The objective was to optimize and validate a thyroglobulin assay on dried whole blood spots and to evaluate thyroglobulin as an indicator of thyroid respo...

BACKGROUND AND PURPOSE Washout thyroglobulin provides evidence for metastatic or recurrent lesions, However, the cutoff value is still controversial. We investigated an optimized cutoff value and indication for the use of washout thyroglobulin from fine-needle aspiration in neck lymph nodes from preoperative or postoperative patients with well-differentiated thyroid cancers. MATERIALS AND MET...

Thyroid tissue obtained from 12 patients with Graves' disease and treated with thionamide drugs for 3-7 mo before subtotal thyroidectomy, from 12 patients with Graves' disease, similarly treated, and given 50 mug of triiodothyronine (T3) for 10 days before surgery, and from 12 euthyroid patients with solitary cold nodules was investigated to compare in vitro iodination of thyroglobulin in toxic...

Background: Polycystic ovarian syndrome (PCOS) is a hyperandrogenic condition characterized by polycystic morphology and chronic oligo-anovulation. When it combines with hypothyroidism hyperprolactinemia, this can have severe consequences, may even lead to infertility.
 Case Presentation: This case study illustrates the complexity of PCOS significance multidisciplinary approach its diagnos...

Previous work (Herscovics, 1969) demonstrated that mannose and galactose are incorporated into the carbohydrate groups of thyroglobulin at different times in the elaboration of this glycoprotein from its subunit precursors. Mannose is incorporated on subunits of thyroglobulin at about the time of their synthesis, whereas galactose is incorporated over 30min later near the time of aggregation of...

As a tool with which to detect iodinated compounds in human thyroid specimens, we have reevaluated a nonincineration technique which has so far been employed in the determination of thyroxine-iodine in peripheral blood. The catalytic action of iodoamino acids in the Ce-As reaction was enhanced by a small amount of Cl2. On the contrary, a large amount of Cl2 inhibited the reaction unexpectedly. ...

The relationship is shown between a concentration of urinary iodine and serum thyroglobulin in population studies carried out on a general population that was randomly selected from the registry of the General Health Insurance Company (individuals aged 6-98 years, 1751 males, 2420 females). The individuals were divided into subgroups with a urinary iodine concentration of <50, 50-99, 100-199, 2...
