Hypothyroidism is known to be associated with mental retardation, motor dysfunction, memory deficits and hearing impairment. In the present study, the functional integrity of the thalamocortical projections to the primary auditory cortex and association cortex has been assessed by using Auditory Evoked Responses i.e Auditory Brainstem (ABR), Mid Latency Response (MLR) and Slow Vertex Response (...

The levels of 6 circulating tumor markers were evaluated in a total of 131 female subjects with altered thyroid states; 36 normal subjects, 46 hyperthyroid patients with Graves' disease, and 49 primary hypothyroid patients. The mean CEA concentration was observed to be significantly higher (p less than 0.02) in hypothyroid patients than in normal and hyperthyroid patients (1.1 +/- 0.1 ng/ml, 0....

Isolated fat cells from hypothyroid rats, in contrast with those from normal animals, lack ability to give a lipolytic response to epinephrine or glucagon. However, activation of triglyceride lipolysis was induced with (N6,02’-dibutyryl cyclic adenosine 3’ :5’-monophosphate), or a combination of epinephrine and phosphodiesterase inhibitors. Adenylyl cyclase was activated by catecholamines or gl...

Hypothyroidism may result in accelerated atherosclerosis. Hyperhomocysteinaemia is an independent risk factor for premature atherosclerotic vascular disease. The aim of the present study was to assess plasma total homocysteine (tHcy), folate and cobalamin concentrations in hypothyroid patients before and after treatment. Thirty-one hypothyroid and thirty health young women were studied. The hyp...

The effects of long-term cold exposure on muscle and liver mitochondrial oxygen consumption in hypothyroid and normal rats were examined. Thyroid ablation was performed after 8-wk acclimation to 4 degrees C. Hypothyroid and normal controls remained in the cold for an additional 8 wk. At the end of 16-wk cold exposure, all hypothyroid rats were alive and normothermic and had normal body weight. ...

thyroid hormones and omega-3 are essential for normal brain functions. recent studies have suggested that omega-3 may protect against the risk of dementia. the aim of this study was to investigate the effect of hypothyroidism on spatial learning and memory in adult male rats, the underlying mechanisms and the possible therapeutic value of omega-3 supplementation. thirty male rats were divided i...

Secondary hypothyroidism is caused by treatment for hyperthyroidism and is a chronic condition. After adequate treatment, people can continue to experience persistent physical and depressive symptoms. There is a lack of research into the psychological factors involved in the condition, such as how people adjust to hypothyroidism. The study used Kelly‘s (1955) Personal Construct Theory to explor...

This study was designed to evaluate the zinc metabolism in adults of both sexes with thyroid disease. Plasma and erythrocyte zinc concentration and urinary zinc excretion were investigated. The mean concentration of plasma zinc in hypothyroid patients and in euthyroid patients, previously either hyperthyroid or hypothyroid, was lower than that of control subjects, whereas no statistically signi...
