Hypoglycin A, the causative agent of the Jamaican vomiting sickness, produced a marked increase in concentration of isovaleric acid in the plasma of rats, when administered in a single dose. alpha-Methylbutyric acid, a position isomer, also accumulated. The use of hypoglycin A reproduced some
OBJECTIVE
We assessed whether wheat bran extract (WBE) containing arabinoxylan-oligosaccharides (AXOS) elicited a prebiotic effect and modulated gastrointestinal (GI) parameters in healthy preadolescent children upon consumption in a beverage.
METHODS
This double-blind randomized placebo-controlled
Isovaleric acidemia (IVA) is an autosomal recessive disease of the leucine metabolism due to a deficiency of isovaleryl-CoA dehydrogenase (IVD). We report the case of a six-month-old girl admitted with a seven-day history of fever, cough, stridor, vomiting, and respiratory distress. Second-degree
The effect of glycine administration on acute leucine loading (125 mg/kg) was tested in a patient with isovaleric acidemia. Serum isovaleric acid at 1-3/4 hr after the leucine loading alone was elevated to 5.60 mg/100 ml and urinary isovaleryglycine excretion was 9.90 mg/mg creatine/24 hr. Whe the
The three first cases of isovaleric acidemia diagnosed in Scandinavia are described. The disorder is characterized by periodic vomiting, lethargy and coma accompanied by ketoacidosis and a "sweaty feet" odour. These attacks are often triggered of by upper respiratory tract infections or by ingestion
Evidence is presented for the specific in vivo and in vitro inhibition of isovaleryl CoA dehydrogenation by hypoglycin A and its derivative, alpha-ketomethylenecyclopropylpropionic acid. alpha-Methylbutyryl CoA dehydrogenation was also impaired, but the degree of inhibition was much lower.
Median nerve stimulation (MNS) had been performed in the existing literature to alleviate symptoms of nausea and vomiting. The observed facilitative effects are thought to be mediated by the vagal pathways, particularly the vagus nerve (VN) brainstem nuclei of the dorsal motor nucleus of vagus and
