The effects of leukotrienes C4, D4 and E4 (LT C4, D4 and E4) were studied in isolated preparations of guinea-pig and human myocardium in order to assess their contribution to cardiac dysfunction associated with systemic anaphylaxis. LT C4, D4 and E4 all caused long-lasting and dose-related decreases in the contractile force and coronary flow rate of the(More)
BACKGROUND Quality of recovery (QoR) after anesthesia is an important measure of the early postoperative health status of patients. The aim was to develop a short-form postoperative QoR score, and test its validity, reliability, responsiveness, and clinical acceptability and feasibility. METHODS Based on extensive clinical and research experience with the(More)
The intron/exon organization of the human gene for glycogen phosphorylase has been determined. The segments of the polypeptide chain that corresponds to the 19 exons of the gene are examined for relationships between the three-dimensional structure to the protein and gene structure. Only weak correlations are observed between domains of phosphorylase and(More)
Platelet-activating factor is a novel phospholipid that has been implicated as an important mediator of acute allergic reactions. The intravenous administration of acetyl glyceryl ether phosphorylcholine, a pure, synthetic platelet-activating factor, causes electrocardiographic changes in the rabbit similar to those which are characteristic manifestations(More)
The cloning of the genes that encode for prostaglandin (PG) receptors has resolved much of the complexity and controversy in this area by confirming the classification proposed by Coleman, et al. Two issues that remained unresolved were (1) the inability of the EP2 agonist butaprost to interact with the cloned putative EP2 receptor and (2) molecular(More)
Immunologic immediate hypersensitivity reactions of the heart are characterized by tachycardia and arrhythmias caused by the release of endogenous cardiac histamine. The contribution of SRS-A to anaphylactic cardiac dysfunction was indirectly assessed by the use of the selective SRS-A receptor antagonist FPL 55712. In the presence of FPL 55712 the(More)
A single overlay plaque assay was designed and evaluated for infectious hematopoietic necrosis virus. Epithelioma papillosum carpio cells were grown in normal atmosphere with tris(hydroxymethyl)aminomethane- or HEPES (N-2-hydroxyethylpiperazine-N'-2-ethanesulfonic acid)-buffered media. Plaques were larger and formed more quickly on 1- to 3-day-old cell(More)
Ergot derivatives, such as bromocriptine, lergotrile and pergolide, are potent dopaminergic agonists in various biological systems. In topical doses ranging from 0.001 to 1% applied unilaterally, each agent produced dose-related ocular hypotension in normal rabbits. Utilizing an intraocular pressure (IOP) recovery rate method (aqueous formation index), each(More)
