Changes in the heparin neutralising activity of platelet poor plasma after immunisation.
نویسندگان
چکیده
Acute myocardial disease, which may be associated with abnormal platelet activity, has been reported after routine immunisation. Thirty-two army apprentices undergoing immunisation were studied for changes in the heparin neutralising activity (HNA) of platelet poor plasma. HNA increased after immunisation. This increase in HNA may represent an increase in platelet activation but may also relate to changes in acute phase proteins. These changes were not observed in elderly subjects undergoing immunisation with influenza vaccine.

Efficacy of a New Autologus Platelet Gel: in Vitro Study
Abstract Background Autologus platelet gel is easy to prepare and is relatively low cost. The aim of this study was to prepare and evaluate in vitro efficacy of autologus platelet gel. Materials and Methods In this experimental study, platelet concentrate and platelet poor plasma were prepared with aphaeresis method. Thrombin was prepared by mixing the plasma with calcium. Thrombin activity...
متن کاملChanges in thrombin-stimulated platelet malondialdehyde production during the menstrual cycle.
Forty normal women had thrombin-stimulated platelet malondialdehyde (MDA) production measured during their menstrual cycle. Twenty women in this group were taking the combined oral contraceptive pill (OCP). Platelet MDA production was found to fall by 30% during normal menstruation and the week when the subjects were not taking a combined OCP, but it remained constant throughout the remainder o...
متن کاملInhibitory activities of platelet-rich and platelet-poor plasma on the growth- of pathogenic bacteria
Background:The utility and efficacy of novel materials in tissue regeneration and antimicrobial therapy are contingent upon the employment of either blood derivatives rich in platelets or platelet-poor-plasma (PPP). This effect is largely mediated by the increased or decreased concentration of platelets in the plasma. The current study aimed t...
متن کاملIn vitro Evaluation of the antibacterial activity of Platelet-rich Plasma against Selected Oral and Periodontal Pathogens
Background: Despite the availability of a wide range of antibiotics, bacterial infections are among important challenges for the healthcare system. Therefore, the introduction of new antimicrobial preparations such as platelet-rich plasma (PRP) could be suggested theoretically as a preventive measure for bacterial infections. We aimed to evaluate the in vitro antibacterial activity of PRP again...
متن کاملAntithrombotic potential of dihomo-gamma-linolenic acid in man.
The effects of orally ingested dihomo-gamma-linolenic acid (DHLA), the natural biosynthetic precursor of prostaglandin E1 (PGE1), were assessed in human volunteers. Single doses of DHLA (0.1--2g) increased the proportion of DHLA relative to arachidonic acid in plasma and platelets and also increased the ex-vivo capacity of platelets to produce PGE1 and PGE2. More pronounced effects were observe...
