Myeloperoxidase-mediated platelet release reaction.
The ability of the neutrophil myeloperoxidase-hydrogen peroxide-halide system to induce the release of human platelet constituents was examined. Both lytic and nonlytic effects on platelets were assessed by comparison of the simultaneously measured release of a dense-granule marker, [(3)H]serotonin, and a cytoplasmic marker, [(14)C]adenine. Incubation of platelets with H(2)O(2) alone (20 muM H(...
متن کاملPlatelet release reaction and intracellular cGMP.
Enchanced cAMP concentrations inhibit the aggregation and release reaction of isolated human platelets and platelet-rich plasma to all known inducing agents. An opposing role for cGMP in this phenomenon has been proposed by some but not by others, and the function of cGMP in this secretory process is unclear. To further elucidate the role of cGMP in the release reaction, the effect of increased...
متن کاملPlatelet-release reaction in myocardial infarction.
A study was made of the platelet-release reaction in heparinised platelet-rich plasma taken from 26 patients, of whom 22 had sustained a definite and four a possible myocardial infarction, and from 54 age-matched controls. No significant differences in reaction were observed between the two groups. Signficant differences were seen, however, between eight patients who died within a year after in...
متن کاملInhibition of platelet release reaction by acetylsalicylic acid.
The inhibitory potency and duration of action of single doses of aspirin B.P., claradin (a low sodium effervescent preparation of acetylsalicylic acid) and aloxiprin (an aluminium co-polymer of acetylsalicylic acid) on platelet release reaction induced by adenosine diphosphate (ADP) were studied in seventeen volunteers. Aspirin B.P. and claradin at 300 mg and 150 mg inhibited release reaction i...
متن کاملThe role of platelet membrane phospholipids in the platelet release reaction.
The structure and function of the platelet surface was probed by phospholipase C (Clostridium perfringens) which hydrolyzes membrane phospholipids, particularly phosphatidylcholine. Platelet phospholipids were susceptible to phospholipase C, and extent of hydrolysis was dependent on concentration of phospholipase C and Ca(++). Phospholipase C (0.15 U/ml) with Ca(++) (0.55 mM) hydrolyzed 15.6% p...
