conclusions based on our results, it seems that there were no cases of obi among chronic hcv-infected patients with thalassemia and bleeding disorders, particularly hemophilia. however, to improve decisions concerning obi screening, especially in transfusion centers, and concerning the use of comprehensive screening methods, more original studies with more precise laboratory techniques and larg...

Routine hematological tests were performed in a family which was at risk for sickle cell disease. Cellulose acetate electrophoresis and Triton PAGE were employed to differentiate between various variants of hemoglobin. Based on the data a pedigree was constructed which indicated that few members of the respectively had received the S gene, some of them were sickle cell disease while few were si...

The efficiency and the viability of three hemoglobin screening programs were investigated. They were offered on a voluntary basis to a Brazilian population and started with the analysis of blood donors, pregnant women and students. The hemoglobin screening was done through optional exams which included electrophoresis of hemoglobin and complementary hematological tests. A total of 13,670 people...

a bstract background: the improved physical action following administration of supplements to bodybuilders was supported by changes in laboratory parameters. despite the fact that these supplements are sometimes associated both advantage and side effects, this study were conducted for the purpose of evaluating the possible effects of some commonly used supplements in bodybuilders on the hematol...

three hundred and fifteen day -old chickens were used to test the relationship between oxygen-derived free radicals and the biochemical, hematological and pathological alterations(associtd with ascites). they were randomly divided into three experimental groups and ascites were developed in two groups of animals by exposing them to low temperature or administration of triiodothyronine (t3,), an...

Styrene monomer is a high volume chemical used chiefly in production of polystyrene. A clinical survey of 493 production workers was undertaken at the oldest and largest monomer production, polymerization, and extrusion facility in the U.S. Relative exposure durations and levels were obtained from occupational histories. Significant differences between the high and low exposure groups were foun...

Microcytosis is a common hematological finding, usually related to iron deficiency or beta-thalassemia. When both of these conditions are excluded, alpha-thalassemia must be considered in the differential diagnosis. No simple biochemical test is able to diagnose the alpha-thalassemia trait. Using PCR amplification of the breakpoint in deletional forms, and amplification of the alpha 2 gene and ...

Viral infections remain one of the most frequent complications in patients with hematological malignancies, especially in those receiving an allogeneic stem cell transplantation. Viral infections result from reactivation of latent infection rather than from acquisition of new infection. Infections caused by herpes viruses, including cytomegalovirus and Epstein-Barr virus, respiratory viruses an...

In the recent article(l), authors have diagnosed vitamin A toxicity after measles immunization on the basis of bulging anterior fontanelle within 24 h of intake of 1,00,000 IU of Vitamin A given along with measles vaccine. They have not estimated vitamin A levels or demonstrated any other change of vitamin A toxicity such as liver enzymes, hematological indices or tests for bone changes. Withou...
