A 67-year-old womanwith pulmonary embolism was suspected to have /J-thalassemia based on microcytosis, hemolysis and a negative red cell stability test. The DNAsequencing analysis of /3-globin gene, however, revealed the deletion of three nucleotides within codon 127-128, leading to substitution of glutamine and alanine residues at 127 and 128 by proline, namely Hb Gunma. This mutant is charact...

BACKGROUND Shock absorbing insoles are effective in reducing the magnitude and rate of loading of peak impact forces generated at foot strike during running, whereas the foot impact force during running has been considered to be an important cause of intravascular hemolysis in long distance runners. Objective of this study was to evaluate the intravascular hemolysis during running and compare t...

We report hemolysis due to glucose-6-phosphate dehydrogenase (G-6-PD) deficiency in two Egyptian monozygotic brothers, at the onset of diabetes type 1. Hemolysis occurred following the treatment of hyperglycemia and ketoacidosis (one twin). It was related to unknown G-6-PD deficiency. The fall in glucose availability after the treatment of hyper glycemia is proposed as a possible etiology for h...

Sickle cell disease (SCD) is a monogenetic disorder caused by single amino acid change in the beta globin gene. This mutation facilitates the production of unstable sickle hemoglobin (Hb S) which upon deoxygenation forms higher order aggregates which cause erythrocyte rigidity. These rigid cells block the microvasculature resulting in vaso-occlusion, tissue ischemia, organ damage, pain and deat...

The literature indicates that acute pancreatitis is a complication of massive hemolysis with a prevalence of about 20%. We describe an experimental model of hemolysis-induced acute pancreatitis. Hemolytic anemia was induced in rats by a single ip injection of 60 mg/kg of 20 mg/ml acetylphenylhydrazine (APH) in 20% (v/v) ethanol on the first experimental day (day 0). One hundred and fifty Wistar...

We studied the influence of low doses of γ radiation (from 0.04 to 1.8 mGy) on the stability of human red blood cells (RBC) from healthy donors and diabetic patients using absorption spectroscopy. Because of the alteration of many enzymatic pathways in diabetic RBCs resulting in strong modification of the lipid and protein membrane components one could expect that the ionizing γ-radiation shoul...

Ten consecutive patients with myeloysis. One patient had a positive sucrose fibrosis were examined for the following hemolysis test and low red cell ACHE. signs of PNH: Ham’s test, the sucrose The remaining patients had no signs of hemolysis test, low red cell acetylcholinPNH. In two of the patients, the PNH esterase (ACHE) activity and intrasigns disappeared after splenectomy. The vascular hem...

Morganella morganii is a facultative gram-negative and anaerobic rod. It may be a cause of devastating infections in neonates and immunocompromised hosts. Some bacterial infections such as Clostridium and Vibrio are associated with hemolysis. However, massive hemolysis caused by M. morganii sepsis has not yet been reported. We observed a 59-yr-old man who had chemotherapy-induced neutropenia an...
