25. Determination of lead chelated with ethylenediaminetetra-acetic acid in blood after precipitation of protein with perchloric acid
Cernik, A. A. (1970).Brit. J. industr. Med.,27, 40-42. Determination of lead chelated with ethylenediaminetetra-acetic acid in blood after precipitation of protein with perchloric acid. A method is described for the determination of lead in whole blood containing ethylene-diaminetetra-acetic acid. Proteins were precipitated by 2·0 m perchloric acid. The ion

26. Determination of chelated iron in the urine
A simplified wet-ashing technique is described for the determination of chelated iron in the urine, with special reference to DTPA-bound iron. The procedure dispenses with the need for quantitative transfer, and gives corresponding economy in time, labour, and glassware without loss of precision. The standard error of the mean estimate of a triplicate determ

27. Opsonic requirements for phagocytosis of Streptococcus pneumoniae types VI, XVIII, XXIII, and XXV.
An assay system employing radiolabeled, heat-killed Streptococcus pneumoniae and human polymorphonuclear leukocytes was utilized to study serum pneumococcal opsonic requirements. Comparing the kinetics of phagocytosis in normal serum, heat-inactivated serum, immunoglobulin G (IgG)-deficient serum, C2-deficient serum, and magnesium dichloride ethyleneglycol-t

30. Influence of the Alternate Complement Pathway on Opsonization of Several Bacterial Species
In normal human serum chelated with magnesium (10 mM) and ethylene glycotetraacetic acid (10 mM) (MgEGTA), the classical pathway of complement activation is blocked; however, the alternate pathway of complement activation is intact. Diplococcus pneumoniae, Staphylococcus albus, Streptococcus viridans, Streptococcus faecalis, and Serratia marcescens were opso

32. Differential ferrioxamine test in idiopathic haemochromatosis and transfusional haemosiderosis
The differential ferrioxamine test measures the amount of body iron as ferrioxamine (Fv) chelated by a standard dose of desferrioxamine.

33. A ligand-specific action of chelated copper on hypothalamic neurons: stimulation of the release of luteinizing hormone-releasing hormone from median eminence explants.
We have previously shown that chelated copper stimulates the release of luteinizing hormone-releasing hormone (LHRH) from isolated hypothalamic granules. In this study, we wished to ascertain if chelated copper acts on hypothalamic neurons to stimulate LHRH release and, if so, what is the ligand specificity of this interaction. An in vitro system of explants

34. Comparison of ethyleneglycoltetraacetic acid and its magnesium salt as reagents for studying alternative complement pathway function.
The divalent cation chelators, ethyleneglycoltetraacetic acid (EGTA) and its magnesium salt, MgEGTA, were compared in studies of alternative complement pathway function. EGTA (0.01 M) inhibited both the rate and the amount of complement activation by zymosan whether compared to nonchelated serum or to serum chelated with MgEGTA (0.01 M). The rate of alternat

35. Serum ferritin in children with thalassaemia regularly transfused
A controlled trial of continuous chelation therapy in regularly transfused children with homozygous β-thalassaemia has been in progress at the Hospital for Sick Children since April 1966. In the sixth and seventh years of the trial the effect of this treatment on iron overload has been assessed by estimating serum ferritin levels and liver iron concentratio

36. Role of outer membrane barrier in efflux-mediated tetracycline resistance of Escherichia coli.
Accumulation of tetracycline in Escherichia coli was studied to determine its permeation pathway and to provide a basis for understanding efflux-mediated resistance. Passage of tetracycline across the outer membrane appeared to occur preferentially via the porin OmpF, with tetracycline in its magnesium-bound form. Rapid efflux of magnesium-chelated tetracycl
