The present study evaluated the usefulness of the 1-min leukocyte esterase-nitrite tests in a tertiary-care hospital as a screening procedure to detect significant bacteriuria and correlated the findings with culture results. A total of 531 urine samples were reviewed, of which 484 were evaluated. Of the evaluated samples, 113 positive cultures (23.4%) were found, of which 93 (82.3%) were detec...

Leucocyte elastase may be involved in the structural modification observed in the atherosclerotic process. Therefore, we tested the usefulness of leucocyte elastase plasma level determination as a marker for atherosclerosis. Plasma levels of elastase were determined by ELISA in 100 consecutive patients (mean age 56 +/- 9.8 years) admitted to hospital for coronary angiographic investigation of c...

BACKGROUND AND PURPOSE Diffuse involvement of the meninges by remote granulomas in Wegener's granulomatosis is rare. This study reports the radiolabeled leucocyte imaging findings in five such patients. The diagnosis was made by MR imaging in five patients and confirmed in four by findings at meningeal biopsy. The potential role of serial radiolabeled leucocyte examinations in assessing treatme...

Background-An important action of interleukin 8 (IL8) is stimulation ofgranulocytes. The object of this study was to assess the contribution ofIL8 to the leucocyte-endothelial celi interactions associated with intestinal inflammation in the rat. Methods-Two indomethacin injections (48 and 24 hours prior to the experiments) induced a longlasting ileitis in rats. The number of adherent and emigra...

1. In nine patients with chronic liver disease photoreceptor function was tested, by measurement of the B-wave amplitude of dark adaptation by electroretinography, and the leucocyte content and plasma concentration of zinc were determined. 2. Four of the patients were leucocyte zinc-depleted and had impaired photoreceptor function, but this was normal in the five with normal leucocyte zinc cont...

A six year follow up study of 750 aluminium smelter workers was undertaken to evaluate the relationship between the leucocyte count at the start of the study and the rate of decline in lung function. An inverse relationship between the leucocyte count and the forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) was present cross sectionally irrespective of cigarette smo...

Lactotransferrin was highly purified from lysates of human neutrophilic leucocytes by immuno-affinity chromatography. A comparative analysis of the molar carbohydrate compositions of human leucocyte lactotransferrin and human milk lactotransferrin reveals that the glycans of leucocyte lactotransferrin differ essentially by the absence of fucose residues. Structural analysis combining methylatio...

1. We have measured adenosine 5'-triphosphate (ATP) levels in isolated leucocyte suspensions from patients with renal failure. 2. Leucocyte ATP is reduced in these patients, unlike erythrocyte ATP which is known to be elevated in uraemia. 3. The relevance of reduced leucocyte ATP to the abnormalities of cation transport and cell function which occur in uraemia is discussed.
