Background: Leptin, a 16-KDa peptide hormone secreted from theadipose tissue, plays an important role in the regulation of energyintake and expenditure and body weight regulation; furthermore,it has a regulatory function on the reproductive system. The aimof this study was to assess the relationship between serum leptinlevels and sex hormones in psoriatic patients and control groupand to determ...

Protein carboxymethylase, an enzyme capable of methylating proteins and polypeptides, was purified from bovine pituitary. The anterior pituitary hormones, luteinizing hormone, follicle-stimulating hormone, adrenocorticotropic hormone, growth hormone, thyroid-stimulating hormone, and prolactin, were found to be substrates for this enzyme. The posterior pituitary hormones, oxytocin and vasopressi...

Empty sella is often an incidental magnetic resonance imaging (MRI) finding. It may be partial or complete and can primary secondary due to intracranial hypertension, radiation exposure pituitary apoplexy. Most of the patients are asymptomatic but features panhypopituitarism develop in some. This a case report 70-year-old female who presented with complaints vomiting, altered sensorium irritabi...

Serum thyroid stimulating hormone and thyroxine concentrations were monitored in 42 infants who had been treated for congenital hypothyroidism. Serum thyroid stimulating hormone concentrations were raised in 22 of the infants (52%) at 2 to 4 months, in 16 (38%) at 5 to 11 months, in 14 (33%) at 12 to 18 months, and in eight (19%) at 2 to 4 years. Serum thyroxine and the dose of L-thyroxine/kg/b...

Background: Equine follicle stimulating hormone (eFSH) is a pituitary heterodimeric glycoprotein consists of noncovalently linked of generic alpha subunit and a hormone specific beta subunit. The molecular weights of the subunits are similar and about 16 KD. In general, FSH plays a key role in controlling vertebrate gonadal functions. In female mammals, ovarian maturation and follicular growth ...

SUMMARY We studied the chronic effect of chemical gases on pituitary-gonad axis of victims of Iran and Irag war. The patients that their poisoning were higher than three years, selected. After clinical evaluation, and role out of systemic disease 168 victims were tested for testosterone, follicular stimulating hormone and leutinizing hormone. Comparison of results control group (n=200) and wi...

Germline nonautoimmune hyperthyroidism due to an activating mutation in the thyroid stimulating hormone receptor gene is an uncommon disease. To date 32 different mutations have been described. The severity of the hyperthyroid symptoms is variable and phenotype differences have been described in subjects harboring the same mutation. This paper describes a family with a mutation in codon 431 of ...
