This study addresses how growth during sensitive developmental periods and genes may affect hormone levels in late adolescence. We analyzed hormone levels of dehydroepiandrosterone sulfate (DHEAS) and insulin-like growth factor-I (IGF-I), which are hypothesized to be two pathways linking early growth with adult diseases (such as type 2 diabetes and cardiovascular disease) via their effects on e...
To determine the effect of elevations of plasma lipids on growth hormone secretion in humans, paired insulin hypoglycemia tests and paired arginine infusion tests were performed on eight and six normal female volunteers respectively. On 1 of the 2 test days for each growth hormone stimulus, subjects were given 60 g corn oil (Lipomul) 3 hr before testing followed by intravenous heparin (5000 U) ...
The oral clonidine test was compared with the standard intravenous insulin hypoglycaemia test in 41 children and adolescents with short stature. In those without growth hormone deficiency clonidine provoked a significantly higher mean plasma growth hormone response and gave fewer false subnormal responses (apparent growth hormone deficiency) than insulin. Children with psychosocial deprivation ...
Diabetes in acromegaly is usually non-insulin dependent and is secondary to insulin resistance caused by growth hormone excess. Diabetic ketoacidosis is a result of relative insulin deficiency and is a rare feature of acromegaly. We describe a case of acromegaly presenting with diabetic ketoacidosis. We demonstrate that growth hormone excess can cause diabetic ketoacidosis in the presence of re...
Although impaired glucose tolerance affects 36% and overt diabetes mellitus can be seen in 30% of cases with acromegaly, diabetic ketoacidosis is rarely reported in patients with this disease. We present an unusual complication of acromegaly: a 22 year old woman with amenorrhea (6 month ago) and blurred vision of left eye (4 month ago) referred to Ghaem neurology clinic in Mashhad. With a gro...
were performed on premature or term infants using blood preserved with acid citrate and glucose. The plasma concentrations of glucose, free fatty acids, insulin, glucagon, and growth hormone were measured in the donor blood and in blood from the infant at different times during the transfusion. The total amounts of metabolite and hormone infused and removed from the infant were calculated. The ...
critical in the control of the secretion of insulin like growth factor I' Interestingly, high concentrations of this growth factor have been found in patients with progressive exudative lesions.' Our findings suggest that growth hormone is not essential for the initiation and development of diabetic retinopathy. Our patient's normal concentrations of insulin like growth factor I and her growth ...
Received: 23 Apr , 2013 Accepted: 28 Jun , 2013 Abstract Background & Aims: Concentrations of certain substances in follicular fluid (FF) may related to fertilization outcome. The study aim was to identify FF markers with which to predict embryo implantation potential. Materials & Methods: Concentrations of selected hormones, cytokines and growth factors in FF samples obtained during assi...
