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...

BACKGROUND: The ABO blood groups result from DNA sequence variations, predominantly single nucleotide and insertion/deletion polymorphisms (SNPs and indels), in the ABO gene encoding a glycosyltransferase. The ABO blood groups A(1), A(2), B and O predominantly result from the wild type allele A1 and the major gene variants that are characterized by four diallelic markers (261G>del, 802G>A, 803G...

BACKGROUND Data on frequency distribution of ABO-Rh blood groups in cardiac syndrome X (CSX) patients are not available. We aimed to investigate the distribution of ABO-Rh blood groups in these patients. MATERIALS AND METHODS A total of 247 CSX patients' records were reviewed in a cross-sectional study from 2006 to 2010. One hundred forty six patients (59.1%) were female, and the mean patient...
