Although the exact mechanism of action of platelets is miot entirely known, there are evidences that they play a role imi the first stages of hemostasis by agglutinatimig at the woumid and later...

Blood platelets are considered to be a peripheral marker in schizophrenia and other psychiatric disorders. Oxidative stress in schizophrenia may be responsible for changes in platelet metabolism and function; therefore, the aim of this study was to examine and compare the generation of superoxide anions and activity of an antioxidant enzyme (glutathione peroxidase [GPx]) in blood platelets in p...

HIV (human immunodeficiency virus) belong to family of human retroviruses lentivirus subfamily. This virus hits the patient’s immune system by destroying important cells that fight against disease and infection. Different parameters like Total Leucocytes count TLC, Hb level, platelets among male female were observed.Study different in patientsfrom areas Punjab, Pakistan. Complete blood (CBC), L...

BACKGROUND Cocaine ingestion has been associated with thrombosis of coronary as well as peripheral arteries, but the mechanism by which cocaine promotes thrombus formation is unknown. Accordingly, we determined whether cocaine activates human platelets by flow cytometric analysis of whole blood to which cocaine was added. METHODS AND RESULTS Activated platelets were detected by "two-color" fl...

Background: Excessive ordering of blood components imposes heavy costs to blood transfusion centers and increases the amount of blood product wastage due to lack of their use. In recent years, attempts have been made against unnecessary blood and blood product requests in our country. We aimed to investigate the frequency of blood and blood product wasting in healthcare centers of Yazd city in ...

IPID SYNTHESIS by platelets and white cells is veII established. White cells can incorporate fatty acids into neutral lipid and phospholipid esters.1’2 Acetate is incorporated into neutral lipids and phospholipids of human blood by leukocytes and platelets, but only to an insignificant extent, if at all, by red blood cells.3 However, oxidation of fatty acids by the formed elements of human bloo...

1. A new fixing solution is described, which preserves the platelets and prevents contact hemolysis of the erythrocytes, so that counts of both corpuscles may be made in the same preparation. 2. Comparative counts of platelets in arteries and veins show that arterial blood contains a larger number of platelets than venous blood. This difference is accentuated under experimental conditions that ...

In this paper, we discuss an application of the method Digital Laser Speckle Image Correlation (DIC) for studying aggregation function platelets in whole blood with maximum standardization pre-analytical and analytical stages study. Materials images are provided, methods explained.

Basis and Objectives: Platelets and/or red blood cells transfusion usually are performed in patients with Immune Thrombocytopenic Purpura (ITP) who are submitted to splenectomy. The purpose of this study is to test if preoperative embolization of splenic artery is able to prevent platelets and/or red blood cells transfusion. Patients and Methods: All patients submitted to splenectomy for purpur...
