Measurement of Lead in Biological Materials by Combined Anion-Exchange Chromatography and Atomic Absorption Spectrophotometry Open
A method for determination of lead in blood, urine, and tissue is presented. This procedure combines the selective concentration of lead by, and the elimination of large quantities of alkali metals on, an anion-exchange resin with the spee…

The Effect of Mucopolysaccharide Linkage Region and Intrachain Alkali Labilities on Chain Weight Determination Open
The validity of the reducing end group (copper reduction) method for determination of chain weight of chondroitin sulfate is shown by comparison with chain weight determination from linkage region components, xylose and galactose. It is es…

Gas Chromatographic Determination of Lower Alcohols in Biologic Samples Open
A procedure is described for the simultaneous determination of methanol, ethanol, and isopropanol in biologic samples, using a low-cost gas chromatograph. A combination of the use of anhydrous calcium sulfate (Drierite) absorption of most …

THE ABSENCE OF THE HETEROPHILE REACTION IN THE SPINAL FLUID IN INFECTIOUS MONONUCLEOSIS Open
The spinal fluid was studied in twenty cases of infectious mononucleosis proved by clinical picture, blood studies and serological examination. It may be concluded that in acute cases of infectious mononucleosis, the heterophile antibody d…
