Normal hematologic values obtained with a Coulter counter, model S.

A survey was made of hematologic values obtained with the Coulter Counter, Model S, at American Medical Laboratories, Inc. Blood specimens from 6,887 outpatient men, women, and children were analyzed according to age and sex. Patients being seen by nephrologists, hematologists, and oncologists were excluded from the study. The mean values for white blood cell counts, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration correlated well with values frequently quoted as normal. However, the mean values for hemoglobin, hematocrit, and red blood cell counts were slightly lower than the commonly accepted normal mean values. This may be a result of newer and more accurate methods of hematologic analysis.

"B" cell origin of malignant cells in a case of American Burkitt's lymphoma. Characterization of cells from a pleural effusion.

Ninety-eight percent of the cells isolated from a malignant pleural effusion in a case of American Burkitt's lymphoma showed membrane fluorescence to antihuman IgM antisera, while only 2% of the cells formed spontaneous rosettes with sheep red blood cells. It is concluded that the Burkitt cells in the malignant effusion are derived from bursal equivalent lymphocytes. Epstein-Barr (E-B) viral titers to both viral capsule antigen and early antigen were not elevated. The significance of these findings is discussed.

Nitroblue tetrazolium reduction test in pregnancy.

The use of the nitroblue tetrozolium (NRT) dye reduction test as a screening method for bacterial and fungal infections is now widely recognized. Levels have been reported to be falsely elevated in the pregnant state. This report includes a prospective study which showed that the results of this test in 124 pregnant women were indistinguishable from those of a normal control population. Seven of 8 elevated levels were attributable to infection or allergy. With this data, it is concluded that the NBT test can be used to screen for bacterial and fungal illnesses in a febrile pregnant patient as well as in the general population.
