The aim of this study was to investigate if there is an association between ABO blood group and severity of chronic periodontitis. Data were collected from 161 chronic periodontitis patients. Medical history, dental history, and periodontal parameters (such as probing depth, clinical attachment loss, and distance from cemento-enamel junction to gingival margin, furcations, and mobility and miss...

ABO blood groups and secretor status are important in clinical and forensic medicine and in relation to some diseases. There are geographic and racial differences in their frequencies, but the frequency of secretor status in different ABO blood group systems has not been determined yet. Therefore, the aim of this study was mainly to determine this point. Blood and saliva from 762 randomly selec...

BACKGROUND Blood is man's complete and unchangeable identity. The ABO and Rh groups are recognised as major and clinically significant blood groups. Blood group antigens are not only important in relation to blood transfusion and organ transplantation, but also have been utilised in genetic research, anthropology and tracing ancestral relation of humans. The objective the present study is to ex...

Antigens of the ABO blood group system (i.e., A, B, and H antigens) and Rhesus factor were discovered more than one century ago by karl & steiner [1,2] who is considering the father of transfusion medicine, and with this discovery he enabling physicians to transfuse blood without endangering the patient′s life. The ABO antigens are defined by carbohydrate moieties on the extracellular surface o...

Hepatitis B and HIV infection are two viral infections that represent real global public health problems. In order to improve their management, some hypotheses suggest that genetic predispositions like ABO and Rh blood groups would influence the occurrence of these diseases. The aim of the present study was to examine the association between ABO and Rhesus blood groups and the susceptibility to...

OBJECTIVE To document the distribution of the ABO and rhesus (Rh) blood groups in a random sample of Saudi students from the King Khalid University, Abha, Kingdom of Saudi Arabia, and to compare our results from that of other studies in the Kingdom and elsewhere. METHODS The subjects included in this study were 944 males from the southwest region of Saudi Arabia including Aseer, Jizan, and Na...

Since the work of Boorman, Dodd and Trinick (1949), incompatibility in the ABO system has been recognized with increasing frequency as a cause of haemolytic disease. Robinson, Phillips and Prystowsky (1951), Shumway, Miller and Young (1955), Davidsohn (1956) and others have written on this condition. And yet haemolytic disease due to ABO incompatibility is much less widely known than that due t...

BACKGROUND There is a large amount of evidence that the ABO blood group system may play a role in disease etiology. A relationship between ABO and Rhesus blood groups and cancer risk has been demonstrated in a number of studies. However, in relation to gynecological malignancies, these findings are inconsistent and contradictory. AIM To perform a case-control study for analysis of the distrib...

statement of the problem recent studies have shown a relation between some abo blood types and increased susceptibility to fungal infections. purpose the aim of this study was to determine the frequency of blood groups in patients with denture stomatitis. materials and methods in this descriptive cross-sectional study, diagnosis of denture stomatitis in 100 patients with complete denture, was m...
