چکیده
W i n t r o d u c e d a n e w t y p e o f blood bags from two different manufacturers at our center with diversion pouch and sampling device. Stripping of tube segments was also introduced to have anticoagulated blood in satellite tube. During component preparation, we observed 11 blood bags were showing pinkish to red colored plasma immediately after first centrifugation which was suggestive of hemolysis [Figure 1]. These bags were collected during outdoor blood donation camps and in‐house collection on different occasions over 2‐month period out of total collection of approximately 10,000.

Platelet-Stored Angiogenesis Factors: Clinical Monitoring Is Prone to Artifacts
BACKGROUND The analysis of angiogenesis factors in the blood of tumor patients has given diverse results on their prognostic or predictive value. Since mediators of angiogenesis are stored in platelets, their measurement in plasma is sensitive to inadvertent platelet activation during blood processing. METHODS Variants of blood withdrawal and plasma preparation were evaluated by ELISA for the...
متن کاملThe many ways to cleave hyaluronan.
Hyaluronan is being used increasingly as a component of artificial matrices and in bioengineering for tissue scaffolding. The length of hyaluronan polymer chains is now recognized as informational, involving a wide variety of size-specific functions. Inadvertent scission of hyaluronan can occur during the process of preparation. On the other hand, certain size-specific hyaluronan fragments may ...
متن کاملTransplant-Associated Thrombotic Microangiopathy in Childhood
Vascular endothelium is damaged by toxic agents during the preparation regimen for stem cell transplantation. Microthrombi develop in small arterioles and capillaries and cause partial obstruction. Erithrocytes are subjected to mechanical trauma, and as a result, to hemolysis and fragmentation. Patients have clinical symptoms similar to thrombotic thrombocytopenic purpura (TTP) and Hemolytic Ur...

ABSTRACT Glucose -6-phosphate dehydrogenase (G6PD)deficiency is the most common inheritory enzyme defect in human. With this deficiency, red blood cells are susceptible to hemolysis induced by oxidants .Drage and foods (esp. fava beans) are the most common oxidants that cause acute hemolysis (Favism). Vitamin E.that is an potent antioxidant,was studied in chronic hemolysis of these patients. ...
متن کاملHemolytic Events in Rh Positive Neonates Born to Rh Negative Mothers
Background One of the most important cause of severe neonatal hyperbilirubinemia is hemolysis including Rh incompatibility. The aim of this study was to assess the rate of hyperbilirubinemia due to hemolysis in Rh positive neonates born to Rh negative mothers. Methods In this retrospective study from March 1998 to February 2003, 60 icteric Rh positive newborns that were born to Rh negative m...
