this work analyzes the effects of satureja khuzestanica essential oil (skeo) on the thyroid and antioxidant system, assessed by measuring levels of tri-iodothyronine (t3), thyroxine (t4), thyroid-stimulating hormone (tsh), malondialdehyde (mda), reduced glutathione (gsh), and glutathione peroxidase (gpx) activity. forty adult male sprague dawley rats (225 ± 25 g) were divided into five equal gr...

Studies show that physical inactivity can influence functions of body glands. The main aim of this study was to determine the effects of physical inactivity on thyroid glandfunction in rats. Male Wistar rats were randomly divided into control and immobilized (8h/days for 8 days) animals of 10 in each group. After 8 days, blood samples were collected using cardiac puncture method. Following seru...

The acquired immunodeficiency syndrome (AIDS) follows infection with the human immunodeficiency virus (HIV) after a long and variable period of time. Although HIV can be rapidly cytopathic in vitro for T4 cells, during early in vivo infection, T4 cell numbers are normal and few infected T4 cells can be found. There is increasing evidence that cells of the monocyte/macrophage lineage, including ...

BACKGROUND To investigate thyroid function in preeclamptic patients in comparison with normal pregnant women. METHODS In this analytical cross-sectional study free Thyroxine (T4), and Thyroid Stimulating Hormone (TSH) levels were measured in 100 preeclamptic patients and were compared with Free T4 and TSH levels in 101 normal pregnant women in their third trimester of pregnancy. Patients with...

Since the introduction of sensitive assays for serum thyroid-stimulating hormone (TSH) clinicians have advised hypothyroid patients to adjust dose levothyroxine (L-T4) in order achieve a normal TSH. A minority are dissatisfied with this treatment strategy and experience symptoms. Some indirect evidence suggests that TSH may not necessarily reflect euthyroidism at tissue level treated L-T4. Incr...

The bacteriophage T4 regA gene codes for a regulatory protein that controls the expression of a number of T4 early genes, apparently at the level of translation. Restriction fragments containing the regA structural gene have been cloned into phage M13, and the nucleotide sequence has been determined. Translation of the DNA sequence predicted that regA protein contains 122 amino acids, with a Mr...

OBJECTIVE: To estimate the effect of soybean diet on serum level of thyroid hormone, its metabolites and thyrotropin (TSH) during aging in rats. METHODS: Male Donryu rats were fed laboratory chow containing 40 (Group A) or 10 volume percent (Group B) soybean protein, while controls (Group C) received regular laboratory chow. Groups of 10 animals of each groups were sacrificed by decapitation at...
