Ammonia toxicity: Comparative protective effect of various arginine and ornithine derivatives, aspartate, benzoate, and carbamyl glutamate
Ornithine and arginine compounds were highly effective in preventing an increase in blood ammonia and in preventing or minimizing encephalopathy after acute subcoma, comainducing, or lethal doses of NH ...

Brain monoamines after portacaval anastomosis
Norepinephrine, dopamine, and serotonin, as well as the serotonin metabolite, 5-hydroxy-indoleacetic acid, were measured in whole-brain extracts from rats with a portacaval shunt or sham operation. Norepinephr...

β-Hydroxybutyrate reverses insulin-induced hypoglycemic coma in suckling-weanling mice despite low blood and brain glucose levels
In normal suckling-weanling mice,dl-β-hydroxybutyrate (30 mmol/kg ip) stimulated insulin secretion and reduced plasma glucose levels. In the brains of these animals, glucose levels were tripled due to a reduced r...

Glycerol as an indicator of lipid degradation in bicuculline-induced seizures and experimental cerebral ischemia
Glycerol, the end product of phospholipid degradation, was measured in cat brains under pathophysiological conditions known to cause activation of lipolysis, namely, bicucullineinduced seizures, permanent foca...

Regional glucose andβ-Hydroxybutyrate use by develo** rat brain
Rates of glucose andd-β-hydroxybutyrate use were determined in five brain regions of 20-day-old rats. The regions studied were cerebral cortex, thalamus, striatum, cerebellum, and brain stem. The tracers for dete...

Phosphofructokinase activity in fibroblasts from patients with Alzheimer's disease and age- and sex-matched controls
The activity of the enzyme phosphofructokinase (PFK) was comparable in cultured skin fibroblasts from eight patients with Alzheimer's disease and eight age- and sex-matched controls. Mean activities were simil...

Effects of acute hyperosmolar NaCl or urea on brain H2O, Na+, K+, carbohydrate, and amino acid metabolism in weanling mice: NaCl induces insulin secretion and hypoglycemia
This study compares early and late effects of the injection of hyperosmolar NaCl and urea of equal osmolarity on selected aspects of brain water, electrolyte, carbohydrate, amino acid, urea, and energy metabol...

Dietary supplementation of undernourished rats with soy or safflower oil: Effects on myelin polyunsaturated fatty acids
Undernourished suckling rats were administered, by gastric intubation, either soy oil (which is rich in both linoleic and linolenic acids) or safflower oil (which is rich in linoleic acid but deficient in lino...

Regional blood-brain barrier transport of glucose after portacaval anastomosis
The regional influx of glucose across the blood-brain barrier was measured in rats 5 to 6 weeks after a portacaval anastomosis or sham operation. D-[14C]Glucose was infused intravenously for 15sec while arterial ...

Cerebral metabolic effects of organophosphorus anticholinesterase compounds
Rats treated intravenously with an organophosphoras anticholinesterase compound, paraoxon or soman, were sacrificed 2 to 131 min later, using 0.7sec of focused microwave irradiation (25 kW at 915 MHz). Brain r...

Restraint stress during late pregnancy in rats elicits early hypermyelination in the offspring
Female rats were subjected to a regular, daily schedule of 2 hr of restraint stress during the final 6 days of pregnancy. During the first 2 postnatal weeks, adrenal weights were greater than normal in the off...

Peroxidative aggregation of myelin membrane proteins
The exposure of CNS myelin to reactive oxygen species (ROS) generated by a Cu2+−H2O2 system results in the aggregation of membrane proteins. Integral and peripheral membrane proteins are equally vulnerable and th...

Cerebral aminoacids in portal-systemic encephalopathy: Lack of evidence for altered γ-aminobutyric acid (GABA) function
Construction of an end-to-side portocaval anastomosis in the rat resulted, 4 weeks later, in sustained hyperammonemia and two- to threefold increases in brain ammonia. Measurement of cerebral amino acids using...
