The effect of the calcium ionophore A23187 on the release and metabolism of [3H]arachidonic acid was examined in normal polymorphonuclear leukocytes and those obtained from patients with chronic granulomatous disease. The ionophore A23187 which stimulates oxidative metabolism in normal polymorphonuclear leukocytes was ineffective in increasing oxidative metabolism (chemiluminescence) in polymor...

The aim of the present study was to investigate blood parameters and subsequent fertility in cows with or without increased postpartum polymorphonuclear neutrophil activity. conducted 15 Brown Swiss between 1-3 lactations. Polymorphonuclear activities were assessed at 10±4 days before after parturition. which maintained their phagocytic oxidative burst activites compared prepartum period classi...

The effect of localised acute inflammation, produced by a small intestinal anastomosis on the effluent lymph of the gastrointestinal tract and on the efferent lymph of the mesenteric lymph glands has been studied in rats. There is a progressive increase in the output of lymph from the gastrointestinal tract in rats with an intact anastomosis, but a decreased output in animals with a disrupted a...

HYPOTHESIS The levels of intestinal interleukin 10 and interleukin 4, inhibitors of intercellular adhesion molecule-1 (ICAM-1) expression, decline with total parenteral nutrition (TPN). These cytokine changes induced by lack of enteral nutrition may increase ICAM-1 expression, resulting in polymorphonuclear neutrophil accumulation in intestine. DESIGN Prospective randomized experimental trial...

Myeloperoxidase aids in clearance of microbes by generation of peroxidase-mediated oxidants that kill leukocyte-engulfed pathogens. In this review, we will examine 1) strategies for in vitro evaluation of myeloperoxidase function and its inhibition, 2) ways to monitor generation of certain oxidant species during inflammation, and 3) how these methods can be used to approximate the total polymor...

A case of neutropenia associated with cephapirin therapy is described. After discontinuation of cephapirin therapy, the neutrophil count returned to normal. Bone marrow examination revealed a marked reduction of polymorphonuclear leukocytes beyond the metamyelocyte stage and eosinophilia.
