Collagen - Induced Platelet Aggregation With and Without Leukocytes In Patients and Control Subjects

چکیده

Background and Purpose Platelet aggregation plays an important role in the pathogenesis of thromboembolic cerebrovascular disease. Leukocytes can efficiently stimulate as well as inhibit platelet aggregability. We studied the influence of leukocytes on collagen-induced platelet aggregation in patients with acute ischemic stroke. Methods We investigated 23 patients within 2 days after stroke and 23 healthy ageand sex-matched control subjects and determined collagen-induced platelet aggregation in platelet-rich plasma with or without addition of polymorphonuclear or mononuclear leukocytes. Results Platelet aggregation without leukocytes tended to be lower in patients than in control subjects (P=.O6). Mononuclear leukocytes reduced (P=.O18) and polymorphonuclear

Perioperative changes in platelet count and function in patients undergoing cardiac surgery

Background: Patients undergoing cardiac surgery are at increased risk of bleeding due to multifactorial coagulopathies. In the present study, we aimed at investigating the changes in platelet count and function during and after surgery as well as determining the association of the platelet dysfunction with bleeding and transfusion requirements in these patients.    Methods: A total o...

Acute nicotine treatment accelerates photochemically induced platelet aggregation in cerebral arterioles of mice: an in vivo study

When tobacco is smoked, chewed or snuffed, nicotine is absorbed by the lungs or mucous membrane and quickly moved into the bloodstream, where it is circulated throughout the brain. In fact nicotine is highly dangerous to be consumed in any form. The present study was conducted to know the adverse effects of nicotine on the platelet aggregation in cerebral microvessels of mice. Male mice of aver...

Presence of factors that activate platelet aggregation in mitral stenotic patients' plasma

BACKGROUND: Although the association between mitral stenosis (MS) and increased coagulation activity is well recognized, it is unclear whether enhanced coagulation remains localized in the left atrium or whether this represents a systemic problem. To assess systemic coagulation parameters and changes in platelet aggregation, we measured fibrinogen levels and performed in vitro platelet function...
