although cellular immunity involving activated macrophage is important in resistance to brucella infections, serum factors and polymorphonuclears (pmns) play some role in the initial responses to brucella infections. in this research, we studied respiratory burst of pmns against opsonized yeast and opsonized inactivated brucella melitensis in chronic brucellosis patients and controls with no pr...

The effect of pentoxifylline (Trental) on the phagocytic capacity, cAMP levels, and superoxide anion production of human peripheral blood monocytes and polymorphonuclears (PMNs) was studied. The drug inhibited the phagocytosis of latex particles by both monocytes and PMNs in a dose-dependent manner. In addition, superoxide anion production during the phagocytic process was also reduced followin...

The cellular composition of the granulocytic series in normal human bone marrow was studied in aspirates of different volume. An increase in the proportion of polymorphonuclears was observed in samples of more than 1 ml, thus indicating a dilution of bone marrow by peripheral blood. Certain data from the literature, referring to the differential count in the bone marrow granulocytic series, are...

was passed. Temperature was 99.4?F. but the pulse had risen to 102 though still of good volume. He vomited a small quantity of bilious matter. A differential leucocytic count showed 89 per cent polymorphonuclears. A provisional diagnosis of " obstruction with commencing peritonitis" was made and laparotomy decided on. At 9-30 a.m. when the patient arrived on the table his general condition was ...

Purpose: To compare the use of polypropylene and PTFE meshes in the treatment of incisional hernias made experimentally on Wistar rats. Methods: The experiment used 24 Wistar rats divided into three cohorts: C-A (ressection of a segment of abdominal wall), E-A (ressection and placement of PTFEe mesh), E-B (resection and placement of polypropylene mesh). After 28 days, the mesh and the surroundi...

OUR attention recently has been attracted by the occurrence in Purdvsburn Fever Hospital of several cases of mneningitis in which the causal organism was the hzinophilits influienzcw. A study of all admissions to Purdysburn Fever Hospital since its opening in November, 1906, shows that the first case (liagnosed as influenzal meningitis was adlmitted inl October, 1929. Another case followe(d in ...

Hydrogen peroxide (Η2Ο2) is produced during a variety of cellular procedures. In this paper, the regulatory role of Η2Ο2, in Escherichia coli phagocytosis by the human polymorphonuclears, was investigated. White blood cells were incubated with dihydrorhodamine (DHR) in order to study H2O2 synthesis and E. coli-FITC to study phagocytosis. Flow cytometry revealed increased synthesis of H2O2 in po...

was a left-sided pleuritic effusion, so extensive as to displace the heart to the right side, and to make the spleen palpable below the left costal margin. The blood contained 9,860 white cells per c.m., and a differential count showed 73 per cent, polymorphonuclears, 15 per cent, small lymphocytes,. 10 per cent, large lymphocytes, 1 per cent, eosinophils, and 1 per cent, basophils. The tempera...

A simple chamber was constructed for observation of cells at 37 degrees C and under high magnification. Rabbit peritoneal histiocytes observed in this chamber manifested a constant interaction, which lasted as long as the preparation itself. This interaction consisted of formation of cytoplasmic bridges and flow of cytoplasm between the cells. Lung macrophages formed bridges both between themse...
