Storage of granulocytes for transfusion has not showed no functional impairment after 24 hr of been practical because it has been considered storage at 4#{176}C. With further storage, all granuthat granulocyte function in bank blood is relocytes showed a loss of NBT activity. Howtamed for only a few hours after collection. In ever, after 48 and 72 hr. granulocytes from the present study, granul...

Indium 111 leucocyte scanning was used to examine the kinetics of granulocyte localisation in five patients with lobar pneumonia and four patients with lung abscess. Lung abscesses showed dense accumulation of labelled granulocytes within four hours of injection. In contrast, in all cases of lobar pneumonia granulocytes failed to accumulate over a period of up to 24 hours despite evidence of ad...

In a prospective study, 40 episodes of granulocytopenia (granulocytes less than 500/mm3) in 34 patients were analyzed. During 52.5% of these episodes there was proven infection; these infections were present for only 24.4% of the 1,435 granulocytopenic days. The risk of infection and mortality were closely linked with extreme granulocytopenia (granulocytes less than 100/mm3). Of the episodes wi...

Of 400 female and 58 normal nonommunized male sera approximately 10% were cytotoxic for a panel of allogeneic granulocytes. Sera with strong alloreactivity were also autoreactive, which emphasized the large autoimmune component of most alloantisera against granulocytes. The cytotoxic granulocyte autoantibodies were complement dependent, of the IgM class, and exhibited optimum cytotoxic activity...

The diagnosis of myelodysplastic syndromes (MDSs) relies largely on morphologic and karyotypic abnormalities, present in about 50% of patients with MDS. Array-based genomic platforms have identified copy number alterations in 50% to 70% of bone marrow samples of patients with MDS with a normal karyotype, suggesting a diagnostic role for these platforms. We investigated whether blood granulocyte...

Determination of magnesium in mononuclear blood cells may provide useful information about intracellular magnesium. Mononuclear blood cell preparations are frequently contaminated with granulocytes. We determined the normal reference interval for magnesium content and concentration of granulocytes and compared it with magnesium in mononuclear blood cells. The mean granulocyte magnesium concentr...

Granulocyte mobilization into skin abrasions in human volunteers was significantly inhibited by acute alcohol intoxication (45,-800 cells in 8 hr versus 353,000 in normal controls). Alcohol applied locally did not inhibit granulocyte delivery, and protection of the abrasion against heat loss did not reduce the inhibited delivery in intoxicated volunteers. Intoxication inhibited granulocyte adhe...

We have used statistical models based on Fourier transform-infrared spectra to differentiate between the DNA structure of normal granulocytes and those obtained from patients with myelodysplastic syndrome (MDS). The substantial degree of discrimination achieved between the two DNA groups is attributed to differences in the nucleotide base and backbone structures. These structural differences al...

“In-labeled granulocytes were used to study the effects of histocompatibility factors on the migration of transfused granulocytes to infected sites. Fourteen alloimmunized and 20 nonalloimmunized patients received approximately 108 “In-labeled granulocytes from ABO-compatible. non-HIAmatched donors. and scans were performed over known infected sites. All 14 alloimmunized patients had lymphocyto...
