Background: Thyroid hormone variations have been observed according to age and sex. Seasonal effects also induce in thyroid function even people with normal levels. The majority of clinical laboratories follow a single reference range without the consideration age, gender, especially seasonal tests.
 Objectives: To evaluate tests adults functions.
 Methodology: This cross sectional st...

BACKGROUND CYP17, which encodes cytochrome P450c17alpha, mediates both steroid 17alpha-hydroxylase and 17,20-lyase activities, and is essential for the production of glucocorticoids and sex steroids. There is evidence that a common polymorphism in CYP17 (T27C) is associated with estrogen levels, making it a potential marker of disease risk. METHODS This is the first study to examine the relat...

Serum parathyroid hormone (PTH) and calcitonin (CT) levels in fractured racehorses were measured by radioimmunoassay. Racehorses with fracture of large bone such as the radius, third metacarpus, third carpus, digital bone or tibia, showed normal PTH level and elevated CT level in the serum. Serum PTH level was slightly higher in racehorses with sesamoid bone fracture compared to that of healthy...

objective simple febrile seizures are the most common form of childhood seizures,often recurring within the first twenty-four hours. this study was conducted to determine the probable role of low serum  sodium levels in predicting seizure recurrence in febrile children. materials & methods for the study, 226 patients with seizures, aged between 6 months to 5 years, were divided into 3 groups of...

Background Chlorpromazine (CPZ), an antipsychotic drug, is associated with increased risk of sexual dysfunction through increasing prolactin levels. The current study evaluates the effect of CPZ-induced hyperprolactinemia on ovarian follicular growth, gonadotropins, and alteration of ovarian source hormones. MaterialsAndMethods In this experimental study, animals were divided into four groups, ...

Serum anti-Müllerian hormone (AMH) levels are regarded as an age-specific marker for predicting the ovarian reserve in women of reproductive age. Some studies have shown that the luteinizing hormone (LH)/follicle stimulating hormone (FSH) ratio can be used as a predictor of ovarian reserve. The purpose of this study was to assess the variation of LH/FSH ratio with aging and to evaluate the corr...

Serum thyrotropin (TSH), free thyroxine (T4), and free triiodothyronine (T3) levels illustrate the thyroid function set point, but the interrelations between these have never been characterized in detail. The aim of this study was to examine the associations between TSH and thyroid hormone levels in healthy euthyroid twins and to determine the extent to which the same genes influence more than ...

Leptin is a hormone primarily produced by the adipose tissue in proportion to size of fat stores with primary function control lipid reserves,this study aimed evaluate influence hypothyroidisim on serum levels Leptin,CRP and profile,blood sample was collected from 75 women age ranged between (15-49) years 65 them had while 10 samples were healthy control, The results showed no significant diffi...

Background: It is well known that there is a close relationship between elevated androgen plasma levels and the ultrasound findings of stromal hypertrophy in polycystic ovary syndrome (PCOS). The objective of this study was to investigate the effects metformin on the hyperandrogenism and ovarian volume in PCOS. Methods: The study is an unrandomized clinical trial with before–after desig...
