RESUMEN
The aim of this work was to determine the normal values of erythro-, leuko-, and thrombocytes in several groups of population situated in various geographic areas (hills, plain, sea-side), considering that such data could be useful for the delimitation between the normal conditions and the near-normal ones. Sixteen hematologic parameters have been investigated in 2,053 healthy subjects, insisting particularly on those most frequently required in the clinic, i.e., erythrocytes/microliter, hemoglobin (g%), hematocrit (%), leukocytes/microliter, and thrombocytes/microliter. No significant differences related to the geographic areas were recorded. The normal values of the hematologic parameters are presented in separate tables.

A search has been made for corynebacterial phospholipase D, "ovis toxin," a sphingomyelinase (phosphatidylcholine phosphohydrolase, EC 3.1.4.4), among a wide variety of corynebacteria. Phospholipase D activity has been found in strains exhibiting the biochemical properties characteristic of Corynebacterium pseudotuberculosis or of Corynebacterium ulcerans and in no other species of Corynebacterium. Methods for the assay of phospholipase D as a sphingomyelinase and methods for screening for phospholipase D in the presence of Corynebacterium equi on washed sheep blood agar are discussed.

When rabbits were given intramuscular injections of the same quantities of human leukocyte or fibroblast interferons, the former produced moderately higher levels of circulating interferon. Fibroblast interferon was not cleared faster from circulation, nor was direct inactivation by rabbit blood responsible for this difference.
