PURPOSE To compare prospectively the accuracy of positron emission tomography (PET) with leukocytes labeled in vitro with (18)F fluorodeoxyglucose (FDG) versus that of conventional scintigraphy with leukocytes labeled in vitro with (111)In oxine in patients suspected of having infection. MATERIALS AND METHODS This HIPAA-compliant study had institutional review board approval; informed consent...

PURPOSE Leukocyte rheology may play a key role in microcirculation because leukocytes have unique properties, such as large cell volume, high cytoplasmic rigidity, and low deformability. However, only a few methods are available to study the dynamic behavior of leukocytes in retinal microcirculation. The authors developed a new method to analyze directly movements of leukocytes in the retinal v...

The objective of this study was to investigate whether leukocytes could be recruited by rolling leukocytes in a human whole blood model system. In all experiments, either neutrophils, whole blood, or diluted blood was perfused over immobilized E-selectin. With isolated neutrophils (2 x 10(5)/mL), the free-flowing neutrophils were captured by attached neutrophils to form secondary interactions t...

The aim of our study was to determine the phagocytic activity leukocytes and nitrosine tetrazolium test (NST - test) in dynamics experimental periodontitis (EP) immobilization stress (IS). It is established work that indicators studied by us, namely number, index NST increase on 3 rd, 5 th 15 days experiment. above tests have a high diagnostic value allow characterize degree inflammatory proces...

was slightly but significantly higher than that of myeloid and lymphoid leukemia cells. Normal leukocytes were able to maintain their respiratory function in vitro for a longer period of time than were malignant leukocytes. CÛ2stimulated the respiration of both normal and malignant leukocytes, the op timal CÛ2concentration being 1-2 per cent. Normal and malignant leukocytes did not differ sig...

Cigarette smoking is associated with alterations in inflammatory markers among smokers. The present study was carried out to examine the association between smoking habits and total leukocytes count in a group of clinically healthy smokers. The study group consisted of 365 clinically healthy men, aged 20-60 years. Subjects were classified into different groups on the basis of their smoking habi...

Incorporation of glycine-2-14C and A-aminolevulinic acid (ALA)-4-14C into heme was studied in normal and leukemic leukocytes. Activities of ALA synthetase, ALA dehydrase, and heme synthetase in these cells were also measured. ALA synthetase activity and/or incorporation of labeled glycine into heme were demonstrated in leukocytes from patients with acute and chronic myelogenous leukemias. Norma...

Broiler chickens are birds that grow very fast, but have low body resistance and easily stressed. This study aimed to examine the effect of nucleotide turmeric extract (Curcuma longa Linn) on blood profile (erythrocytes, hemoglobin leukocytes) carcass production (weight carcass, weight breast, thighs wings) in broiler chickens. Data was collected using a completely randomized design with 7 trea...
