OBJECTIVE: To evaluate the bone metabolism in obese women by the estimation of selected markers of bone formation. METHODS: The concentration of plasma parathyroid hormone (PTH) and selected markers of bone formation [osteocalcin (BGP) in plasma, carboxyterminal propeptide of type I procollagen (PICP) and alkaline phosphatase (AP) activity in blood serum](More)
OBJECTIVE: To assess the 24 h profile of androgenemia related to the androgens of both the ovarian and adrenal origin in obese women with menstrual disturbances. METHODS: The association of body mass and body fat distribution with circadian variations of selected androgens of ovarian and adrenal origin was examined in 16 obese women with menstrual(More)
We have evaluated the relationship between beta-endorphin (beta-EP) and melatonin (MEL) secretion as determined at 3 h intervals over a 24 h period in 27 normotensive obese women of different phenotypes (12 showing gynoid-type and 15 showing android-type of adipose tissue distribution) as well as in 12 healthy volunteers with normal body weight, aged 30 to(More)
The majority of obese persons have hyperinsulinemia and disturbances in the secretion of melatonin, catecholamines and pituitary, thyroid, adrenal and gonadal hormones. These hormones play an important role in the regulation of collagen metabolism either by acting directly or by influencing IGF-I production. This study aimed at ascertaining whether, and to(More)
The aim of the study was to evaluate insulin (Ins), pituitary hormones (GH, PRL, LH, FSH), sex hormone-binding globulin (SHBG) and insulin-like growth factor-I (IGF-I) under basal conditions as well as the changes in GH, PRL and F levels after insulin-induced hypoglycemia in 21 obese women before and one year after jejunoileostomy as well as in 20 healthy(More)
The association of body mass index (BMI) and body fat distribution (as measured by waist-to-hip circumference ratio; WHR) with serum melatonin (MEL) levels determined at 02 and 14 h were examined in 22 non-operated obese women and 21 obese women who underwent jejunoileostomy for morbid obesity 2 to 6 years earlier as well as in 20 gender and age-matched(More)
The relationship between hypothalamo-pituitary function and various hormonal factors (insulin, cortisol, thyroid hormones, sex steroid hormones, SHBG, IGF-I) was investigated in 34 obese men (16 normotensive and 18 hypertensive) and 15 healthy male volunteers aged 35 to 50 years. Hyperinsulinaemia in obese men was associated with altered(More)
