Leukotrienes can be generated from a wide variety of cells including mast cells and eosinophils. The biological properties of these products include bronchial smooth muscle contraction, stimulation of mucous production, enhancement of vascular permeability, and recruitment of eosinophils. These properties can contribute significantly to the pathobiology of(More)
Pure complexes of dipalmitoyllecithin (DPL, 16:0) which Ca2+, Mg2+ dependent ATPase from sarcoplasmic reticulum are unusual in retaining significant ATPase activity down to about 30 degrees C, well below the transition temperature of the pure lipid at 41 degrees C. A minimum of about 35 lipid molecules per ATPase is required to maintain maximal ATPase(More)
Pig kidney microvillar proteins were extracted with octyl beta-glucoside and reconstituted in liposomes prepared from microvillar lipids of known composition. Four peptidases, namely endopeptidase (EC, aminopeptidases N (EC and A (EC and dipeptidyl peptidase IV (EC, were shown to be reconstituted. At lipid/protein(More)
Ticlopidine is a novel antiplatelet drug reported to cause significant inhibition of several drugs metabolized by the hepatic cytochrome P-450 enzyme system, including antipyrine and theophylline. Warfarin, a racemic mixture of two enantiomers (R and S), is extensively metabolized by the CYP-450 system. S-Warfarin is five to eight times as active as(More)
Asthma is a complex syndrome characterized by variable obstruction to airflow, bronchial hyperresponsiveness, and inflammation. The initiation and propagation of airway inflammation arises from many factors, including mediators generated by resident airway cells and recruited leukocytes (1). Leukotrienes are biologically active fatty acids derived from the(More)
BACKGROUND Eosinophilic inflammation is a feature of asthma. However, serological markers to indicate eosinophil activation in this process are not fully defined. OBJECTIVE To evaluate the relationship of serum eosinophil cationic protein (ECP) to asthma worsening and a marker for treatment effectiveness, 26 adult patients with an asthma exacerbation were(More)
OBJECTIVE Asthma is a significant cause of morbidity and mortality in children. The objective of this study was to determine whether the federal program Head Start in Dane County, Wisconsin, could be used as a mechanism to identify preschool-aged children with asthma. DESIGN Five-year, cross-sectional survey of parents with children enrolled in Head(More)
Asthma treatment is currently undergoing transition as recognition of the important role of anti-inflammatory therapy continues. Asthma is now recognised as a chronic inflammatory process that can be modulated by anti-inflammatory agents. The effectiveness of systemic therapy with corticosteroids has been known for decades, and aerosolised forms of(More)
