Salsalate Inhibition of Thyroid Hormone Transport : A Model of the Euthyroid Sick Syndrome
… of abnormalities is collectively termed the “euthyroid sick syndrome”. One putative mechanism is the presence of circulating thyroid hormone binding inhibitors. Salsalate and salicylate are known to be such inhibitors. The objectives of this study are: to investigate the thyroid hormone …

Effects of Levothyroxine Adminstration and Withdrawal on the Hypothalamic-Pituitary-Thyroid Axis in Euthyroid Dogs
… following levothyroxine administration in euthyroid dogs and the time required for resolution of any suppression. Animals: Twenty-eight healthy euthyroid dogs Methods: A prospective randomized study administering levothyroxine to euthyroid dogs with levothyroxine, for either 8 weeks (group …

Levothyroxine Supplementation in Hypothyroid Bitches During Pregnancy
… levothyroxine dosages in dogs to maintain a euthyroid state. Serum was harvested from blood collected from six bitches with experimentally-induced hypothyroidism that were receiving standard thyroid hormone replacement therapy and from four euthyroid control bitches. Thyroid function tests …

Predictive modelling of external dose rate from radionuclide therapy patients following discharge from hospital
… followed by radiodine ablation in hypothyroid or euthyroid state. Several attempts were made to predict the external dose rate, however, there is a lack of accuracy in predictions from existing models of dose rate decay. Objectives: Published models were compared to actual patient measurements to …

Evaluation of a Feline-Optimized TSH Assay in Cats With Hyperthyroidism and With Non-Thyroidal Illness
… developed. It allows differentiation between euthyroid and hyperthyroid cats. However, the effect of non-thyroidal illness (NTI) on TSH-BAW has not been evaluated. Our objectives included the comparison of serum TSH concentration using both the TSH-CLIA and TSH-BAW assays among hyperthyroid …

Effect of Levothyroxine Administration on Hemostatic Analytes in Doberman Pinschers with von Willebrand's Disease
… levothyroxine administration were evaluated in 8 euthyroid Doberman Pinschers with plasma vWf concentration <30%. Levothyroxine (0.04mg/kg PO q12hours) and placebo were administered for 30 days in a 2-period, 2-treatment, double-blinded, crossover design with a 30-day washout period between …

The Effects of Anesthesia and Surgery on Thyroid Function Tests in Dogs
… thyroid function tests in dogs. Animals: 15 euthyroid mongrel dogs. Methods: Dogs were assigned to one of three groups: control, general anesthesia, and general anesthesia plus abdominal exploratory surgery. Blood samples were collected from each dog immediately prior to pre-medication, 20 …

Evaluation of hemostasis in hyperthyroid cats
… cats with hyperthyroidism and 13 healthy euthyroid cats > 8 years of age were studied. Prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, antithrombin (AT), D-dimers, thrombin-antithrombin complexes (TAT), von Willebrand Factor antigen (vWF:Ag), and activity …

The effects of induced hypothyroidism on the glucocorticoid stress response in Japanese quail (Coturnix japonica)
… thyroidal T4 content, but still maintain euthyroid (normal) concentrations of plasma T4, and a hypothyroid state, in which birds have depleted thyroidal T4 content and decreased concentrations of plasma T4. Thyroid function was assessed by measuring plasma T4 concentrations, thyroidal T4 …

The Effect of Hypothyroidism on Glucose Tolerance in Dogs
… causes insulin resistance. Animals: Sixteen euthyroid bitches were randomly selected and allocated into two groups. In 8 dogs, hypothyroidism was induced by administration of 1 mCi/kg I-131. Experiments were performed on non-anesthetized, fasted dogs in anestrous approximately 12 months after …

Cardiac Biomarkers in Hyperthyroid Cats
… HCM without congestive heart failure, and 19 euthyroid, normotensive healthy cats eight years of age or older. Fourteen of the hyperthyroid cats were re-evaluated three months after administration of 131I. Methods: A complete history, physical examination, complete blood count, serum …

Investigation of a novel modified fixed dose determination protocol for radioiodine treatment of feline hyperthyroidism
… after treatment, cats were determined to be euthyroid, hypothyroid, or hyperthyroid based on serum T4 concentrations relative to an established reference interval. Univariate analysis using Chi-square was used to determine associations between treatment and outcome. Results: There was no …

The role of thyroid and steroid hormones in maturation of the adreline-sensitive reabsorptive mechanism of the fetal lung
… adrenaline- or cyclic AMP-sensitivity which, in euthyroid fetuses, resulted in the capacity to absorb lung liquid from 130 days onwards. Studies in which T₃ and T₄ were infused to thyroidectornized fetal sheep showed that T₃ was required for the normal evolution of the reabsorptive response. …

Effects of Thyroxine and Propylthiouracil Treatment of Young Male Sprague-Dawley Rats on Potassium-Induced Contraction of Thoracic Aorta
… consistently lower tensions compared to the euthyroid controls, while the propylthiouracil treated group generated consistently higher tensions than the control group. Conclusion. It can be determined from this study that treatment with thyroxine and propylthiouracil affected generated …

Basal Release of Endothelium-derived Nitric Oxide in Thyropathologic Rat Aorta
… for hyperthyroid (TRX), hypothyroid (PTU), and euthyroid control (CON) rats. All three measurements were elevated in TXX animals, while PTU rats were determined to have decreased measurements when compared with CON and TRX rats. Animals were sacrificed by either cervical dislocation or …

Central disorders of thyroid function: clinical, radiological and genetic phenotyping
… of patients with RTHbeta as well as healthy euthyroid volunteers. In the fourth chapter, phenotypic differences among patients harbouring micro- versus macro-TSHomas are presented. The second part of this chapter discusses the response of TSHomas to primary medical therapy with somatostatin …

The Epidemiology and Management of Hypothyroidism in General Practice
… (1.17-1.42) and 1.45 (1.31-1.62)] compared to euthyroid individuals after adjusting for age, gender, ethnicity and social deprivation. The increased cardiovascular event risk was greatest in those under 65 years of age with subclinical hypothyroidism [1.26 (1.07-1.49)] compared with those 65+ …

Characterization of 5-Hydroxytryptamine-Evoked Isometric Contractile Responses in Aortic Vascular Smooth Muscle in Thyropathological Rats
… from hyperthyroid (TRX),hypothyroid (PTU), and euthyroid control (CON) rats were mounted in climate controlled tissue baths and subjected to isometric contraction experiments. The endothelium was removed from some rings (denuded) while others were left intact. All rings were initially contracted …
