Abstract Objective The history of the studies on blood groups dates back to early 20th century. More than 600 antigenic structures were detected among 29 blood groups. However, ABO and Rh antigenic structures were taken into consideration in transfusion medicine. Frequency of the blood groups in a community helps the individuals in need and blood bank employees, which could be related to some...

The influence of blood group types on development of brain tumors is unclear since there are conflicting reports from surveys regarding the distribution of ABO blood groups and primary intracranial neoplasms. The present descriptive, retrospective study was therefore made of 907 patients with reliable records for ABO blood groups and proven histological diagnosis who were hospitalized with brai...

Many investigations have proved relations between ABO blood groups with some diseases and factor VIII and von willebrand level in plasma. In this study we investigated a relation between ABO blood groups and factor VIII and IX inhibitors in 102 patients with haemophilia A and 48 patients with haemophilia B.

Therefore, we present regional Veterans Administration Medical Center’s (...
