RÉSUMÉ
Aim: The focus of this work was to investigate any relationship between ABO blood types and malaria parasitaemia among students of a private University based in Western Delta, Nigeria. Study Design: Whole blood samples were obtained from a randomly sampled number of students and dispensed into ethylene-diamine-tetra-acetic acid (EDTA) containers which were appropriately labelled. Collected blood samples were tested for ABO blood types and malaria parasites by standard methods. Data obtained were statistically analyzed. Place and Duration of Study: The study was carried out in the Microbiology and Biotechnology laboratory of Western Delta University, Oghara, Nigeria between May, 2013 to October, 2013. Methods: Venous blood of 2ml volume was obtained by venepuncture from 360 students made up of 150 (41.7%) males and 210 (58.3%) females of 28years average and who were both symptomatic and asymptomatic for malaria due to Plasmodium falciparum. Malaria parasite screening was done by both P. falciparum antigen rapid (Micropoint, USA) test and Giemsa staining. ABO blood typing was done using Monoclonal Antisera A, B and D. Results obtained were analyzed for any association by chi-square statistical method. Results: One hundred and forty one (41.6%) male and 198 (58.4%) female samples were rhesus positive. Nine (42.9%) and 12 (57.1%) males and females respectively were rhesus negative. ABO blood group frequency occurrence was 55.8 %( O), 22.5 %( A), 18.3 %( B) and 3.4 %(AB). A total of 255 (70.8%) students were infected with P. falciparum parasites of which 55.3% and 44.7% were females and males respectively. ABO blood group malaria parasitaemia frequencies were 76.4 %(O), 56.3% (B), 52.4% (A) and O.O% (AB) for non-severe malaria and 70.5% (O), 58.3% (A), 55.6% (AB) and 50.0% (B) for severe plasmodiasis. Whereas there was significant association between malaria infection and gender (P<0.05), there was no significant association between severe and non-severe malaria parasitaemia in relation to ABO blood types (P>0.05). Conclusion: The presence of rhesus negative factor up to 5.8% suggested a gradual and steady rise in the frequency occurrence of the factor when compared to reports of earlier studies. ABO blood groups O and AB recorded the highest and lowest frequencies respectively. The highest parasitaemia rate was observed among group O individuals and also among female O individuals compared to male O individuals. More female than male students suffered from both severe and non-severe forms of plasmodiasis. There was no significant association of all ABO blood types with severe and non-severe malaria parasitaemia clinically implying that all ABO blood types are equally at risk and therefore, available malaria prophylactic and therapeutic strategies should be directed at subjects of all groups.

[Objective] To investigate the relevant factors of neonatal hemolysis, especial y the association between maternal health and neonatal hemolysis. [Methods]O and Rh positive pregnant women in late pregnancy in 497 cases, make physical identification, and track whether the newborn hemolysis. [Results] There were significant differences in different physical pregnant women in the postpartum hemolysis newborn during pregnancy, the partial repletion heat, phlegm dampness postpartum hemolytic disease of the newborn was a high incidence of pregnancy, the lowest incidence rate and quality of postpartum hemolytic disease of the newborn. [Conclusion]The constitution(partial phlegm, partial heat) pregnant women for health care, to achieve peace and reduce neonatal ABO hemolytic was significant.
RÉSUMÉ
Cervical cancer is one of the leading causes of death from cancer among women worldwide and is the most common female cancer in developing countries. In Jamaica, at 27.5 per 100, 000 it is second only to breast cancer as a cause of cancer death in women. Several studies have suggested an association between blood type A and cervical dysplasia/cancer. The aim of this study was to determine whether presence of cervical dysplasia/cancer is associated with blood type A in Jamaican women. Blood was collected from 319 women, 234 cases (abnormal Pap smears) and 85 controls (normal Pap smears). Blood type was determined by the determination of isoagglutinins (anti-A and anti-B). The frequency of types A, B, AB and O in the controls and cases was similar to the Jamaican population. There was a slightly association between blood group O and cervical dysplasia/ carcinoma in Jamaican women when compared with others blood groups. Cervical dysplasia/ carcinoma was strongly associated to the number of sexual partners, number of biological fathers, number of children and the use of hormonal contraceptive.
