The Marsh Test for Arsenic
poisons is arsenic, though the arsenic in question was generally not the pure chemical element itself but rather its oxide, As2O3 or diarsenic trioxide, otherwise known with equal inaccuracy as white arsenic. Indeed, since the most common form of this compound is actually composed of discrete As4O6 molecules, it should more properly be called tetraarsenic hexaoxide. For centuries proof of arsen...

15 صفحه اولAminophylline Infusion Induced Excretion of Magnesium During Magnesium Loading Test in Critically Ill Patients
The aim of this study was to investigate the prevalence of Mg deficiency and effect of aminophylline infusion on urine magnesium concentration after magnesium loading test (MLT). To determine serum Mg, venous blood specimens were obtained just before the first MLT. Two MLTs were performed. The first one was done before starting aminophylline infusion and the 2nd one was done du...
متن کاملMagnesium-selective test strip.
A selective test strip based on an ion-exchange mechanism to determine magnesium is described. This optical and reversible test strip, made on a transparent polyester sheet, has a circular polymeric film of plasticised PVC that contains all of the reagents necessary to produce a response to magnesium, namely, a cation-selective neutral ionophore, 2-amino-N,N'-diheptyl-N,N'-dimethyl-butanediamid...
متن کاملROLE OF MAGNESIUM LOADING TEST IN DETECTING HYPOMAGNESEMIA IN CRITICALLY ILL PATIENTS
Magnesium (Mg) deficiency has not usually been considered in clinical practice due to lack of relevant blood tests and because the symptoms are often vague and nonspecific. Serum concentrations may not adequately reflect Mg status. Mg Loading Test (MLT) can provide infonnation on total body Mg stores. We prospectively studied 21 critically ill patients (10 male, 11 female) admitted to the I...
