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 ...

background: blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. consequently, damage to erythrocytes by free radicals may occur. so it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

the evolution of human blood groups, without doubt, has a history as old as man himself. there are at least three hypotheses about the emergence and mutation of human blood groups. global distribution pattern of blood groups depends on various environmental factors, such as disease, climate, altitude, humidity etc. in this survey, the collection of main blood groups abo and rh, along with some ...

background: safety of blood products and plasma derivates is one of main concerns in transfusion sector. screening of donated blood became an emerging item to large extent because of hepatitis c and b virus, (hcv, hbv) and hiv epidemics especially in blood donation campaign following disasters. in this study we aim to evaluate the pattern of variation of viral infection markers donated at three...

background: determining of gene frequencies of a, band 0 genes from abo blood group system and d and d genes from rhesus system are objectives of the present study. methods: the study was a cross sectional descriptive study. all the voluntary blood donors, 7361 people, attending to the hamadan, iran, blood bank during 1996 were studied. primary information from the sex of blood donors and their...

introduction: it seems that improvement in care and new treatment and screening methods along with better control of diabetes mellitus (dm) has led to a change in incidence of diabetic complications, especially diabetic retinopathy .this study was performed to assess the 4 years incidence rate of diabetic retinopathy in patients with type ii diabetes and factors affecting its progression. metho...

background : magnesium is the second most abundant intracellular cation. it plays an important role in insulin homeostasis and glucose metabolism through multiple enzymatic reactions. with increasing data on magnesium deficiency in diabetic patients and epidemiological studies demonstrating magnesium deficiency as a risk factor for diabetes, it is logical to search for its possible beneficial e...

conclusions our case highlights the fact that the tip of the pulmonary artery catheter can easily advance into a peripheral branch of the pulmonary artery and cause pulmonary venous blood to be sampled instead of pulmonary arterial blood. a variety of monitoring techniques are needed to confirm accurate catheter placement. background pressure and waveform at the catheter tip are continuously mo...

background: the most appropriate route of tranexamic acid administration is controversial. in the current study, we compared the efficacy of intravenous (iv) and topical intra-articular tranexamic acid in reducing blood loss and transfusion rate in patients who underwent primary total knee arthroplasty. methods: one hundred twenty 120 patients were scheduled to undergo primary total knee arthro...
