Baseline, preinduction, postinduction, and postsurgical plasma samples were collected for glucose, insulin, and cortisol in 16 neonates and infants. Glucose infusion rate was maintained constant (mean +/- SD 4.1 +/- 1.2 mg/kg/min) prior to and during surgery; additional fluid losses during surgery were replaced by fluids without dextrose. The weight at the(More)
Most observational studies indicate that hormone replacement therapy (HRT) protects women from cardiovascular disease. Two recent randomized trials, however, showed no reduction in coronary events with HRT in postmenopausal women. A randomized study evaluating subclinical atherosclerosis showed a beneficial effect of estrogen. In the current study we(More)
To characterize further the impact of thyroid dysfunction on the transport of cholesterol in plasma, we studied plasma lipids and cholesteryl ester transfer (CET) in 10 hypothyroid women before and 3 months after thyroid replacement therapy. CET, estimated as the net mass transfer of CE from HDL to the apolipoprotein B-containing lipoproteins (very low(More)
METHODS Apolipoprotein and apoB- and apoA-containing lipoprotein particle concentrations were determined in 10 athyreotic patients 4 weeks after withdrawal of Synthroid replacement therapy [T4, 0.96 +/- 0.66 microgram mL-1; thyroid-stimulating hormone (TSH), 62.7 +/- 22.8 muIU mL-1] and again 4 weeks after reinstitution of treatment. RESULTS Thyroid(More)
A 53-year-old man presented with an acute headache and mental status changes due to rupture of an anterior choroidal artery aneurysm. A preoperative CT scan demonstrated subarachnoid hemorrhage, bilateral optic nerve sheath hemorrhage, and bilateral intraocular hemorrhage. Ophthalmoscopy and B-scan ocular ultrasound disclosed vitreous hemorrhages, features(More)
The adrenal cortex is functionally a three-dimensional gland that secretes glucocorticoids, mineralocorticoids, and sex steroids. Of these three classes of steroids only the gluco- and mineralocorticoid hormones are necessary to sustain life. The availability of sensitive and specific radioimmunoassays has permitted accurate measurement of practically every(More)
A specific and sensitive double antibody radioimmunoassay for human prolactin has been developed utilizing anti-human prolactin and purified ovine prolactin for radioiodination. Employing this radioimmunoassay, as little as 1.5 ng of prolactin can be quantified in a ml of human serum. The prolactin in serum detected by the radioimmunoassay behaved in a(More)
