AIM The relationship between psychological stress and platelet activation has been widely studied. It is well known that platelets may reflect certain biochemical changes that occur in the brain when different mental conditions occur. Platelet 5-hydroxytryptamine (5-HT) is also extensively studied in psychiatry. The mean platelet volume (MPV), the accurate measure of platelet size, has been con...

Introduction. Mean platelet volume (MPV) has been thought as a useful index of platelet activation. It is supposed that MPV is also associated with several inflammatory and infectious diseases. Korea still has a high incidence of tuberculosis (TB). The aim of this study was to investigate MPV as an inflammatory marker in TB patients. Materials and Methods. MPV were determined in 221 patients wi...

OBJECTIVE Increased mean platelet volume (MPV) has been reported in various atherosclerotic diseases. The aim of our study was to investigate the relationship between the atherosclerotic renal artery stenosis (ARAS) and various hematological parameters including MPV. METHODS This study was performed with a retrospective review of the angiographic images of patients who underwent renal angiogr...

An increased mean platelet volume (MPV), measured by the Coulter counter model S plus, was found in 13 of 25 patients with proven septicaemia but in none of 25 patients with localised bacterial infection and negative blood cultures. The increase in MPV was found both in patients with normal and low platelet counts and was not related to a particular micro-organism. Patients who responded favour...

Background: The platelet volume parameters have been widely available as part of full blood count profile on automated haematology analyzers. However, the mean platelet volume (MPV) and other platelet indices are used less often and are poorly understood. Platelet volume data is generated at no extra cost as part of full blood count profile. Low platelet counts can have myriad cause which can b...
