Red Blood cells<br>are protected from lysis caused by complement via the complement regulatory proteins CD35 and CD55.<br>Aim of the study<br>To evaluate CD35 and CD5 in beta thalassemia cases and correlate the serum level of CD35 and CD55 with clinical and hematological<br>parameters.<br>Patients and methods<br>A case control study , included 60 patients who were a known case of β-thalassemia aged between 2_30 years and control group<br>of 20 participants who were healthy and age and sex matched with case group. All hematological parameters were done by automated<br>hematological analyzer.Serum level of CD35 and CD55wereestimated in both patients and control subjects by ELISA<br>technique.<br>Results<br>In this study, Mean RBC, Hb, PCV, MCH, and MCV were significantly lower in thalassemia cases. Serum level of CD35 was<br>significantly lower ,while CD55was significantly higher in patients with thalassemia .There were significant weak positive correlations<br>between CD35and both of RBC and PCV level.<br>Conclusion<br>A low level of CD35 in β thalassemia patients can accelerate the RBC lysis by permitting complement deposition on them<br>.CD35 level showed positive correlation with RBC and PCV and negative correlation with RDW. CD55 is high in thalassemia<br>but with no significant correlation with any of thalassemic patients’ characteristics.</p> 2019-06-01T00:00:00+00:00 Copyright (c) 2019 Iraqi Journal of Cancer and Medical Genetics Re-evaluation of cancer incidence for gender in Genetics Iraq 2023-05-07T06:35:56+00:00 Noah A. Mahmood N.A Thamer [email protected] <p>There has been a rapid increase in the number of computed tomography (CT) scans which utilized for the purpose of disease diagnosis. The radiation exposure can increase the probability of developing different type of cancers. This prospective study was carried out in the Computed Tomography Unit of Al-Imamain Al-Kadhimain Medical City and Al-yarmok teaching hospital in Baghdad Iraq in the period from 1 January to 31 October2018. About 3,758 adult patients (1743 male and 2015 female) with their age ranging from (10-79) who received a CT scan for different site of the body participate in this study. The main results obtained showing that the CT radiation correlated with the age and sex of the patient, with higher risks be expected of thyroid cancer among patients who were younger and female.</p> 2019-06-01T00:00:00+00:00 Copyright (c) 2019 Iraqi Journal of Cancer and Medical Genetics
