Definition: Leucocyte-depleted blood components must contain < 5 × 10 leucocytes per unit (red cells) or adult therapeutic dose (platelets). Practical aspects: To achieve residual leucocyte counts of < 5 × 10, leucocyte-depletion should be carried out under controlled conditions, ideally within 48 h from the collection of the donor unit. The preparation of leucocyte-depleted blood components sh...

The associations between cigarette smoking, plasma leucocyte elastase concentration, peripheral leucocyte count and FEV1 were examined in 148 men, 72 of whom were current cigarette smokers, 40 of whom were ex-smokers, and 36 who had never smoked. All men were part of a long-term survey. Smokers had significantly higher plasma leucocyte elastase concentrations than ex-smokers or those who had ne...

BACKGROUND The aim of this study was to establish the diagnostic value of leucocyte count and neutrophil percentage in both diagnosing simple appendicitis and predicting complicated appendicitis. METHODS The patients who underwent appendectomy with a clinical diagnosis of acute appendicitis (AA) between January 2011 and December 2012 were studied retrospectively. The data of total WBC count, ...

The value of the one minute leucocyte esterase-nitrite chemical strips as a screening procedure for detecting appreciable levels of pyuria and bacteriuria was assessed by comparison with microscopy and culture results. The likelihood that a negative leucocyte esterase result indicated < 10 white cells/cu mm by microscopy (the negative predictive value), was 90 1% and that a negative nitrite res...

BACKGROUND Leucocyte recruitment and inflammation are key features of high dose radiation-induced tissue injury. The inflammatory response in the gut may be more pronounced following radiotherapy due to its high bacterial load in comparison to the response in other organs. We designed a model to enable us to study the effects of radiation on leucocyte-endothelium interactions and on intestinal ...

The value of the one minute leucocyte esterase-nitrite chemical strips as a screening procedure for detecting appreciable levels of pyuria and bacteriuria was assessed by comparison with microscopy and culture results. The likelihood that a negative leucocyte esterase result indicated less than 10 white cells/cu mm by microscopy (the negative predictive value), was 90.1% and that a negative nit...

Leucocytozoon simondi is an apicomplexan blood parasite of waterfowl that frequently causes significant mortality, and thus is expected to provoke a significant immune response in hosts. Using blood smears collected in consecutive weeks from 30 wild-stock mallard, Anas platyrhynchos, ducklings, we tested with repeated measures analyses for associations between leucocyte profiles and L. simondi ...

In a study of a group of 325 blood donors between the ages of 18 and 65 years, the total leucocyte and polymorph counts of the females aged 50 to 65 years were found to be significantly lower than those of the corresponding group of male donors. In the whole series of female donors, there were significantly lower total leucocyte and lymphocyte counts with increasing age and a less significant (...

Hyperleukocytosis is an oncological emergency but is extremely rare in non-malignant conditions. Nucleated RBCs give rise to spuriously high total leucocyte count and cause clinical dilemma. Thalassemia major patients are known to have leucocytosis even after correction for nucleated RBCs. We report a case of undiagnosed Thalassemia major in a 4 month old infant with total leucocyte count highe...
