BACKGROUND Both simple transfusion (ST) of packed red blood cells and automated red cell exchange (RCE) are used in the treatment of acute chest syndrome (ACS). We report our experience using each of these modalities for the treatment of ACS. METHODS Retrospective chart review of patients with ACS treated with ST only (51 episodes, ST group) or RCE performed either at diagnosis (U-RCE group, ...

this study was done to determine whether high or low dose of anti-snake venom (asv) is better in coagulopathy in victims of envenoming by vipers. this retrospective study was conducted on the 154 patients (mean age ± sd, range) of viper snake bites who were referred to the emergency ward of razi hospital, ahvaz, iran over 2 years period (2004 - 2006). according to the treatment dosage the patie...

Costly disposal of uranium (U) contaminated sediments is motivating research on in situ U(VI) reduction to insoluble U(IV) via directly or indirectly microbially mediated pathways. Delivery of organic carbon (OC) into sediments for stimulating U bioreduction is diffusion-limited in less permeable regions of the subsurface. To study OC-based U reduction in diffusion-limited regions, one slightly...

A group of 28 uraemic patients on dialysis treatment were given daily supplements of histidine by mouth. Plasma amino-acid concentration, plasma iron, serum transferrin, packed cell volume, and reticulocyte count were all measured before and after two months of histidine supplementation. The treatment raised the plasma histidine concentration and at the same time there was a rise in transferrin...

AIM To determine if packed red blood cell transfusions contribute to the development of parenteral nutrition associated liver disease. METHODS A retrospective chart review of 49 premature infants on parenteral nutrition for > 30 d who received packed red blood cell (PRBC) transfusions was performed. Parenteral nutrition associated liver disease was primarily defined by direct bilirubin (db) >...

In order to describe two-dimensionally packed cells in epithelial tissues both mathematically and physically, there have been developed several sorts of geometrical models, such as the vertex model, the finite element model, the cell-centered model, and the cellular Potts model. So far, in any case, pressures have not neatly been dealt with and the curvatures of the cell boundaries have been ev...

Reduction of packed cell volume has been recommended as a therapeutic procedure in patients with polycythaemia secondary to hypoxic lung disease. We have investigated the effects of this policy on blood flow and oxygen carriage to the calf in 12 such patients. Packed cell volume was decreased from 0.61 to 0.51 (mean) by isovolaemic haemodilution on a cell separator, with significant reductions ...

sickle cell disease is a genetic haemoglobinopathy with consequent haemolysis and anaemia. it is of interest to study its effect on red cell indices beside haemoglobin concentration.the objective of the study is to determine the values of red cell indices in preschool-age children with sickle cell anaemia.we conducted a cross-sectional study including 97 children with sickle cell anaemia aged s...
