The clinical significance of ABO and Rhesus blood group systems has been well documented. The objective of this study was to determine the frequency of ABO and Rhesus blood groups in blood donors in Lahore, Pakistan, with a view to generate data with multipurpose future practicalities in the field of medicine. Blood groups of 3000 blood donors were determined by commercially available standard ...

the abo and rh blood groups of 9753 pregnant women were determined in the amin maternity hospital, isfahan, iran, from march 23, 1976 to july 11, 1977. their abo blood group frequencies were calculated as follows: 0=38.20%, a=30.67%, b=23.84% and ab=7.26%. also, 90.02% of the women were rh positive and the rest, namely, 9.98% were rh negative.

psoriasis is an common, chronic, recurrent, inflammatory disease of the skin, characterized by red scaling plaques on the skin surface. the morphology of psoriatic lesions allows classification of the different types of psoriasis that included plaque type, pustular type and erythrodermic type. i have studied the relationship between distribution of rh and abo blood groups in 110 psoriatic patie...

ABO histo-blood group antigens have been postulated to modify pathogen spread through the action of natural antibodies and complement. The antigens are generated by a polymorphic glycosyl-transferase encoded by 2 dominant active and a recessive inactive allele. In this study we investigated whether ABO sugars are incorporated into the envelope of HIV-1 virions. HIV vectors derived from cells ex...

In thepresent study, an attempt was made to find the distribution ofblood types in patients with pemphigus vulgaris and chronicplaque type psoriasis.Method: Fifty patients with chronic plaque type psoriasis, 50patients...

In the century since the discovery of the ABO blood groups, numerous associations between ABO groups and disease have been noted. However, the selection pressures defining the ABO distributions remain uncertain. We review published information on Plasmodium falciparum infection and ABO blood groups. DNA sequence information dates the emergence and development of the group O allele to a period o...
