A novel X-linked combined immunodeficiency disease was found in five living males in an extended family in the United States. The age of the affected males ranged from 2.5 to 34 yr. The most prominent clinical abnormalities were a paucity of lymphoid tissue; recurrent sinusitis, otitis media, bronchitis, and pneumonia; severe varicella; and chronic papillomavirus infections. The principal immun...

The determination of magnesium in biological materials by flame photometry.

A method is described for the measurement of magnesium in biological materials and has been applied to the Unicam flame spectrophotometer SP 900. Samples were diluted in 10 mM strontium ethylenedinitrolo tetraacetate (EDTASr), 10 mM potassium carbonate, giving final magnesium concentrations of about 0.1 to 0.2 mM. The EDTASr almost eliminated the depression of magnesium emission by interfering ...

The determination of calcium in biological fluids by flame photometry.

The use of flame photometers has greatly simplified and expedited the estimation of sodium and potassium. Calcium is one of the elements which it is possible to determine by flame photometry, but little advantage has been taken of this fact in biological work for a number of reasons. The concentration of calcium in extracellular fluids is usually less than that of potassium ; a given quantity o...

The determination of serum bicarbonate by flame photometry.

At the present time, the applicability of the flame photometer to the clinical laboratory for determination of the cations sodium, potassium, and calcium in biological fluids has been demonstrated by numerous investigators (l-7). The determination of magnesium in blood serum and plasma by flame photometry has also been described (2, 8). However, analysis of physiologically significant anions in...
