In 17 children on carbamazepine medication alone and 15 children on combined drug regimens, carbamazepine levels were determined in paired samples of serum and mixed saliva by enzyme immunoassay. Carbamazepine levels in serum and saliva were highly correlated in within-patient and between patient series (r = 0.87--0.94). Salivary levels were altered to a(More)
Using a combination of L-phenylalanine inhibition and heat inactivation, the serum alkaline phosphatase (AP) in 2 to 13 year old children without evidence of hepatobiliary, osseous, or intestinal disease was separated in three fractions; i.e. L-phenylalanine sensitive AP (LPSAP), heat-stable non-L-phenylalanine sensitive AP (heat-stable non-LPSAP) and heat(More)
BACKGROUND On-demand relaparotomy has been associated with a slightly decreased mortality compared to planned relaparotomy in the surgical treatment of secondary peritonitis. On-demand relaparotomy must be performed without delay to detect progressing sepsis early, before the onset of multiorgan failure. The aim of the study was to evaluate procalcitonin(More)
BACKGROUND To develop strategies for the prediction of sepsis outcome systemic procalcitonin (PCT) levels were correlated with various clinical parameters. METHODS PCT levels and Acute Physiology and Chronic Health Evaluation (APACHE) II scores were assessed on the day of sepsis diagnosis in a large series (n = 160) of patients developing sepsis after(More)
In 36 epileptic children treated with primidone alone or in combination with additional anticonvulsants, salivary drug levels were compared in resting (I) and in flow-stimulated (II) saliva and were related to the corresponding serum levels. Primidone levels in saliva I and saliva II were highly correlated (r = 0.97) but were significantly (p less than(More)
Short-term treatment of the endothelium with dihydropyridine calcium antagonists resulted in an increased release in NO that is not due to a modulation of L-type calcium channels, because macrovascular endothelial cells do not express this channel. We investigated whether long-term (48 hours) treatment of porcine endothelial cell cultures with the(More)
Serum activities of gamma glutamyl transpeptidase, alanine and aspartate aminotransferases, and alkaline phosphatase were determined in children on long-term treatment with aminopyrine. Gamma glutamyl transpeptidase activity was increased up to 15 times above the upper normal limit in children, who received aminopyrine for two weeks or longer. Livers of(More)
Different observations suggest that dihydropyridine calcium antagonists alter endothelial NO release. Therefore, in a first step we investigated whether part of the nisoldipine (a dihydropyridine calcium antagonist with a possible selectivity for coronaries)-induced vasorelaxation was due to an NO release from the endothelium in porcine coronary arteries.(More)
