The Determination of Sodium in Blood.*
A knowledge of the amount,s of sodium salts in tissues and biological fluids is of considerable importance in reaching an understanding of the physiological r61e of inorganic substances. However, an adequate study of the variations in the amount of sodium in blood, for instance, under different physiological and pathological conditions would be difficult if not impossible by methods1 now in use...
متن کاملEnzymatic determination of sodium in serum.
This is a kinetic assay for measuring serum Na+ concentration based on determination of Na+-dependent beta-galactosidase (EC 3.2.1.23) activity. The method, sufficiently sensitive to measure sub-millimolar concentrations of Na+, was modified by including a Na+-binding agent (cryptand) to provide a linear assay for serum Na+ concentrations between 110 and 160 mmol/L. The assay was developed with...
متن کاملAutomated enzymatic determination of sodium in serum.
An automated method based on the principles of flow-injection analysis is proposed for the enzymatic determination of sodium ion in serum. The method relies on the activation of beta-galactosidase by the analyte. The features of the proposed method include linear range between 1 and 1700 mumol/L, a sampling rate of 50 samples/h, a sample volume of 50 microL, and the absence of interferences fro...
متن کاملEffect of sodium sulfide on Ni-containing carbon monoxide dehydrogenases.
The structure of the active-site C-cluster in CO dehydrogenase from Carboxydothermus hydrogenoformans includes a mu(2)-sulfide ion bridged to the Ni and unique Fe, whereas the same cluster in enzymes from Rhodospirillum rubrum (CODH(Rr)) and Moorella thermoacetica (CODH(Mt)) lack this ion. This difference was investigated by exploring the effects of sodium sulfide on activity and spectral prope...
متن کاملCatalytic Studies of Sodium Hydroxide and Carbon Monoxide Reaction
We have studied the effect of ball milling on alumina mixed nickel, magnetite and Raney nickel on the reaction: 2NaOH(s) + CO (g) = Na2CO3 (s) + H2 (g) and determined the optimum particle size for the catalysts. The best performance was shown by a 2 h ball milled Raney nickel with average crystallite size of 209 Å. This reaction serves the dual purpose of carbon sequestration and yielding hydro...
