A 10 month old female infant was evaluated for severe lactic acidosis. Clinically she was well nourished and had a substantial amount of adipose tissue despite recurrent episodes of acidosis. Her psychomotor development was retarded, her movements were dystonic and generalized seizures punctuated her course. Metabolic abnormalities included elevated blood(More)
Autopsy examination confirmed the diagnosis of subacute necrotizing encephalomyelopathy (SNE) in a 7-month-old male infant who underwent several metabolic studies before death. Intermittent lactic acidemia and fumaric aciduria, an extreme hyperglycemic response to an intravenous bolus of alanine, and an elevated total body flux rate of glucose (58.4 mumoles(More)
Sequential determinations of glucose outflow and inflow, and rates of gluconeogenesis from alanine, before, during and after insulin-induced hypoglycemia were obtained in relation to alterations in circulating epinephrine, norepinephrine, glucagon, cortisol, and growth hormone in six normal subjects. Insulin decreased the mean (+/-SEM) plasma glucose from(More)
The cause of of ketotic hypoglycemia, the commonest form of hypoglycemia in childhood, is not known. The present study was undertaken to determine whether the primary defect in this condition is a deficiency of gluconeogenic precursor(s) or an abnormality in the hepatic gluconeogenic enzyme system. Plasma glucose, alanine, and insulin and blood(More)
Interactions between glucose and arginine and a mixture of 20 amino acids found in normal rat serum were studied in the isolated perfused rat pancreas of normal rats, with release of immunoreactive glucagon and insulin as parameters. Secretion of both pancreatic hormones was low during the steady state, whether glucose (5 mM) was included in the perfusion(More)
To determine whether the differences in fasting glucose responses in men, women and children could be related to differences in glucoregulatory hormone secretion or availability of circulating gluconeogenic substrates, 20 adults (10 men and 10 women) were fasted for 86 hr and 15 children (6.1 +/- 0.8 yr, mean +/- SE) were fasted for 30 hr. Circulating(More)
The ability of iodoacetate, mannoheptulose, and 3-O-methyl glucose to alter islet cell metabolism and glucose-stimulated insulin secretion was examined. A method for the sequential analysis of the releasing and fuel function of glucose in isolated islets was applied. Insulin release was measured by radioimmunoassay and the metabolism of glucose by(More)
Purpose. The partitioning of cetirizine in a phosphatidylcholine liposomes/water system was compared with that of hydroxyzine and acrivastine to gain insight into the mechanisms of interaction of its various electrical species with membranes. Methods. The lipophilicity profiles of the compounds were obtained from equilibrium dialysis and potentiometry, and(More)
