Monoamine oxidase (MAO) exists as two isoenzymes and plays a central role in the metabolism of monoamine neurotransmitters. In this study we compared the neurochemical phenotypes of previously described subjects with genetically determined selective

Serum proteinase activities in head and neck squamous cell carcinoma patients

Autor: V, Bongers, C H, Konings, A M, Grijpma, I, Steen, B J, Braakhuis, G B, Snow

Publikováno v: Anticancer research. 15(6B)

Proteinases are known to be involved in carcinogenesis, and various substrates are now available to measure the activity of these enzymes. No suitable serum tumour marker for head and neck squamous cell carcinoma (HNSCC) exists at this moment. Theref

Re-evaluation of cerebrospinal fluid angiotensin-converting enzyme activity in patients with 'probable' Alzheimer's disease

Autor: C H, Konings, M A, Kuiper, P, Scheltens, A M, Grijpma, W, van Pelt, E C, Wolters

Publikováno v: European journal of clinical chemistry and clinical biochemistry : journal of the Forum of European Clinical Chemistry Societies. 31(8)

Angiotensin-converting enzyme activity was measured in lumbar cerebrospinal fluid from patients with 'probable' Alzheimer's disease (n = 17) and age-matched controls (n = 19), using a spectrofluorimetric method. In contrast to a previous finding, no

Effects of zinc supplementation on zinc status and immunity in haemodialysis patients

Autor: P M, Kouw, C H, Konings, P M, de Vries, J, van der Meulen, P L, Oe

Publikováno v: Journal of trace elements and electrolytes in health and disease. 5(2)

The depression of immunity to various antigens in chronic uremia is a frequently encountered phenomenon. Zinc deficiency might well be an important factor in its genesis. The aim of this study was to investigate the role of zinc deficiency in this re

Comparison of Two Latex Agglutination Test Kits for Serum Myoglobin in the Exclusion of Acute Myocardial Infarction

Autor: Freek W.A. Verheugt, C H Konings, A J Funke Küpper

Publikováno v: Annals of Clinical Biochemistry: International Journal of Laboratory Medicine. 26:254-258

SUMMARY. The Myolex (Orion) and the RapiTex (Behringwerke) latex agglutination tests for the rapid detection of elevated levels of serum myoglobin were studied prospectively in patients suspected of acute myocardial infarction, who were admitted to h

Measurement of antitryptic activity of serum with a centrifugal analyzer

Autor: C H Konings

Publikováno v: Clinical Chemistry. 23:1760-1763

The Selected Method [Clin. Chem. 20, 396 (1974)] for the enzymatic assay of alpha1-antitrypsin in serum has been adapted for use with the E.N.I.-GEMSAEC. With alpha-N-benzoyl-D,L-arginine-p-nitroanilide as substrate, the difference between the trypti

Arginine pharmacokinetics in humans assessed with an enzymatic assay adapted to a centrifugal analyzer

Autor: C H Konings, T W van Haeften

Publikováno v: Clinical Chemistry. 35:1024-1026

Arginine is used in supra-physiological concentrations as an insulin secretagogue, in both in vitro and in vivo studies. To investigate the pharmacokinetics of arginine in humans, we have developed a rapid, automated assay of arginine in serum, based
