To assess the influence of fasting of the alpha- and beta-adrenergic receptor activities of human adipocytes, subcutaneous adipose tissue was obtained from normal obese subjects in the fed state and after 3 days of fasting. Isolated cells prepared from the adipose tissue were incubated with epinephrine, 10(-6)M, and in the presence of the alpha-blocker phentolamine, 10(-5)M, and the beta-… Read More
Adult obese human subjects with a normal or slightly disturbed oral glucose tolerance test, were submitted to a 7-day fast. Initial serum triglyceride levels were inversely related to the Intralipid fractional removal rate, reflecting the close dependency of triglyceridemia on clearance efficiency; the correlation was less significant on the 5th day of fasting. The direction of the change in… Read More
An analysis of the change in total body nitrogen during fasting shows that it declines exponentially, a small fraction being lost rapidly (t 1/2 of a few days), and the remainder being lost slowly (t 1/2 of many months). The obese faster loses N, and weight, at a slower relative rate than the nonobese; and the ratio of N loss to weight loss during an extended fast is inversely related to body… Read More
In obese females, 50 g of alanine given orally on the fifth day of fasting, produced a decrease in urinary sodium that persisted the following day. Plasma renin did not increase the day following alanine intake.
A 38-hr fast was used as a provocative test in patients suspected of having defects in muscle substrate utilization. In five controls and nine patients, exercise capacity and respiratory exchange ratio were determined before and at the end of the fast. Blood was collected at intervals during the fast from ten controls and nine patients for creatine kinase (CK), free fatty acids, (FFA) beta-… Read More
This paper describes the clinical manifestations and the significance of the fasting blood glucose-insulin relationship and the prolonged fasting test in the diagnosis of insulinoma. Pre-and postoperative results are reported. In addition, a description is given of the angiographic demonstration and the results of the surgical removal of the insulinomas.
UNLABELLED: The effects of total fasting for 31 +/- 10 days followed by re-alimentation with an 800 calorie diet on thyroid function, i.e. T4,T3,rT3,RT3U (resin T3 uptake), and TSH, and on TBG levels in serum were studied sequentially in obese hospitalized patients (N=18). Additionally, cortisol, growth hormone, prolactin, parathyrin and free fatty acids were followed as… Read More
The urine of a child who presented with an episode of a disease resembling Reye's syndrome was found to contain large quantities of the dicarboxylic acids adipic and suberic acids, as well as the glycine conjugate of suberic acid, suberyl glycine. A variety of other dicarboxylic acids, both saturated and unsaturated, were also found in the urine at the time of the attack. It was found… Read More
