Supportive evidence for altered platelet function in the dived rat
decompression animal rat platelet
2009/7/20
A study was conducted on the changes in platelet function and platelet count in the Sprague-Dawley rat induced by a bends-producing N2-O2 compression-decompression cycle. In those instances where mild...
Dive-induced modifications in platelet kinetics in rats
decompression platelet kinetics rat animal
2009/7/20
The effect of a simulated dive to 8 ATA on platelet kinetics was studied in normal and splenectomized male and normal female rats. Platelet production and consumption was measured in vivo 1 h and 1 da...
Effects of aspirin and dipyridamole on platelet function,hematology,and blood chemistry of saturation divers
decompression human drug aspirin platelet saturation
2009/7/17
Twenty-four young male divers were assigned randomly to 4 treatment groups: Group I received aspirin (325 mg) three times daily; II received dipyridamole (75 mg) three times daily; III received both d...
An apparatus which enables aggregating agents to be added to a stirred suspension of platelets subjected to a pressure of up to 600 ATA is described. The ensuing aggregation reaction is monitored opti...
A method for production of N2 microbubbles in platelet-rich plasma in an aggregometer-like apparatus,and effect on the platelet density in vitro
decompression human platelet
2009/7/14
The mechanisms involved in the interactions between microgasbubbles and platelets are not clear. The platelet aggregatory response to agonist-induced, receptor-mediated stimuli has been studied extens...
Effects of platelet antagonists on the reduction in platelet density caused by microbubbles in vitro
decompression human Platelet-rich plasma
2009/7/14
Platelet-rich plasma (PRP) was stirred and incubated at 37 degrees C with N2 microbubbles in vitro in the presence and absence of platelet antagonists. The N2 microbubbles acted as a platelet agonist,...
Platelet count in deep saturation diving
Moon,RE Fawcett,TA Exposito,AJ Camporesi,EM Bennett,PB Holthaus,J
2009/7/8
Platelet counts were measured in 10 divers during the course of 4 experimental deep dives (450 and 600 m) and different anticoagulants were tested. The use of sodium citrate as an anticoagulant was as...
Hyperbaric oxygen as a signal transducer: upregulation of platelet derived growth factor-beta receptor in the presence of HBO2 and PDGF
ear hyperbaric wound air platelet
2009/6/8
The purpose of this study was to test the hypothesis that hyperbaric oxygen (HBO2) may function by modifying the signal transduction pathway of growth factors or their receptors, or both. Studies were...
Platelet aggregation and release function in hyperbaric oxygenation
hyperbaric Platelet aggregation Platelet
2009/6/8
The aim of the study was to investigate the acute and chronic effects of hyperoxygenation on platelet aggregation and adenosine triphosphate (ATP) release. To observe the acute effects of hyperbaric o...
Effects of platelet-activating factor and hyperbaric oxygenation on antioxidant defense and duodenal contractility
hyperbaric superoxide dismutase platelet antioxidant
2009/6/5
Platelet-activating factor (PAF) is a phospholipid mediator with potent biological effects on organisms. Some investigators have previously postulated that PAF exerts its effects by producing oxygen f...
Environmental stress on diving-induced platelet activation
decompression air platelet activation Environmental stress diving
2009/6/5
Platelet activation has been suggested to play an important role in the pathogenesis of prethrombotic states and thus may be responsible for decompression illness during compressed air (scuba) diving....
Platelet function in humans is not altered by hyperbaric oxygen therapy
Hyperbaric Oxygenation platelet ATP Osteoradionecrosis Humans
2009/6/2
A pilot survey of platelet function was performed on 6 patients undergoing hyperbaric oxygen therapy (2.0 ATA O2 for 2 hours, 6 days/week) for prophylaxis against osteoradionecrosis. Blood was drawn i...
Effects of hyperbaric oxygen and platelet derived growth factor on medial collateral ligament fibroblasts
Hyperbaric Oxygenation collagen collagen fibrils platelet-derived growth factor-BB platelet medial collateral ligament fibroblast animal rabbit
2009/6/2
This study investigated hyperbaric oxygen (HBO2) and platelet-derived growth factor-BB (PDGF-BB) to determine their combined effects on fibroblasts from rabbit medial collateral ligament (MCL). METHOD...
Induction of platelet aggregation in vitro by microbubbles of nitrogen
nitrogen platelet aggregation drug human
2009/3/26
Microbubbles of nitrogen gas act as a platelet agonist, but the biochemical mechanisms involved in bubble-induced platelet activation are not well known. One characteristic property of a platelet ago...
