the study has strived to compare the leucocyte-esterase stripe activity on sputum samples with gram-stained direct smear microscopy. this is for the demonstration of white blood cells (wbcs) and so to develop a simple method for selecting suitable sputum samples for cultural examination and laboratory diagnosis. . a total of 17(34.0%) out of 50 samples studied were shown to be unsuitable for mi...

background: the aim of this study was to investigate the effect of hemiscorpius lepturus venom on leukocytes and the leukocyte subgroups in peripheral blood of rat. methods: in this experimental study, sixty n-mari rats were divided into three groups of 20 rats. then the rats in each group were divided into four subgroups based on the blood sampling time that was 2, 6, 24 and 48 hours after the...

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...

BACKGROUND Pancreatic infiltration by leucocytes represents a hallmark in acute pancreatitis. Although leucocytes play an active role in the pathophysiology of this disease, the relation between leucocyte activation, microvascular injury and haemorrhage has not been adequately addressed. METHODS We investigated intrapancreatic leucocyte migration, leucocyte extravasation and pancreatic microp...

1. The dose-response curve for sustained infusions of leucocyte pyrogen has been demonstrated, and an optimum dose indicated for leucocyte pyrogen clearance experiments. 2. The lungs, liver and small bowel are not significantly involved in removal of leucocyte pyrogen from the circulation in conscious rabbits. 3. A single circulation through one kidney removes up to half of the infused dose of ...

Background: The peripheral leucocyte count is an important predictor of morbidity and mortality. Hence, host and environmental factors influencing the peripheral leukocyte count are of interest. The influence of smoking on Total Leucocyte Count and Differential Leucocyte Count was investigated. Aims & Objective: To see the influence of smoking on Total Leucocyte Count (TLC) and Differential Leu...

Background: Urinary tract infection is a common disease in childhood. The aim of this study was to determine the diagnostic performance of urinary analysis, assess the role of urine culture in determining its necessity and evaluate etiologic agents and antimicrobial resistance patterns in children with urinary tract infection.Methods: Our study was made by evaluating the patients who applied to...

A study of leucocyte response to infection, polymorphonuclear leucocyte chemotaxis and bactericidal activity, and nitroblue tetrazolium (NBT) reduction in children with kwashiorkor was undertaken and compared with a control group. The results show that total leucocyte counts were depressed in children with kwashiorkor, and lymphopenia was not infrequent. NBT reduction was normal. Abnormal polym...

Differential white blood cell counts are essential diagnostic parameters in veterinary practice but knowledge on the genetic architecture controlling variability of leucocyte numbers and relationships is sparse, especially in swine. Total leucocyte numbers (Leu) and the differential leucocyte counts, i.e. the fractions of lymphocytes (Lym), polymorphonuclear leucocytes [neutrophils (Neu), eosin...
