Fasciola hepatica releases large amounts of proline into the bile of its host. Significant increases in the levels of other amino acids in the bile also occur. The present investigation examines whether proline and these other amino acids may play a role in inducing the anemia that frequently
A secondary anemia is characteristic of infections with the liver fluke, Fasciola hepatica, and previous studies had suggested that proline released by the worm might be involved in producing this condition. In the current study the effect of fascioliasis on erythropoiesis was compared to the
BACKGROUND
Anemia is common in patients with chronic heart failure (CHF) and is associated with a poor prognosis. However, only a minority of patients with CHF have impaired renal function or underlying hematinic deficiencies. It has been shown that inhibition of the renin-angiotensin system is
A hitherto undescribed, unstable hemoglobin was discovered in a four-year-old Japanese girl with relatively severe hemolytic anemia requiring monthly blood transfusion. Although no abnormal hemoglobin was detectable by electrophoresis at pH 8.6 and 7.0, heat denaturation and isopropanol tests gave
OBJECTIVE
Fanconi Anemia, an autosomal recessive disorder, is characterized by chromosomal abnormality leading to birth defects, progressive bone marrow failure, and a high probability of developing malignancy at an early age. Head and neck squamous cell carcinoma and myeloid leukemia are the major
PRP, administered intraperitoneally into NZB mice, twice a week, at doses 0.01-1 microgram per mouse, significantly lowered the incidence of positive Coombs' reaction and prolonged the mean age of the mice. The effect of PRP on survival of mice was better when the treatment with PRP started early
BACKGROUND
Oral Submucous Fibrosis (OSMF) is a premalignant condition with potential malignant behaviour characterized by juxta-epithelial fibrosis of the oral cavity. In the process of collagen synthesis, iron gets utilized, by the hydroxylation of proline and lysine, leading to decreased serum
gamma-Glutamylcysteine synthetase (GCS) catalyzes the initial and rate-limiting step in the biosynthesis of glutathione. gamma-GCS consists of a heavy and a light subunit encoded by separate genes. Hereditary deficiency of GCS has been reported in 6 patients with hemolytic anemia and low erythrocyte
In fascioliasis, anemia is a well-recognized symptom but its etiology is controversial. There is disagreement on whether hematophagia occurs, and if it does, whether it is sufficient to produce the anemic symptoms observed. Another opinion is that a toxic substance emanating from the fluke causes
OBJECTIVE
To confirm the mutation of ALAS2 gene is the cause of sideroblastic anemia in a family.
METHODS
Polymerase chain reaction (PCR) was used to amplify the microsatellite DXS 991, DXS 1199 in the chromosome Xp11.22 linked gene ALAS2 and haplotype analysis was performed in a kindred with 2
Hb Madrid, in which the alanine residue at beta115 (G17) is replaced by proline, results in a moderately severe hemolytic anemia due to the disruption of an alpha helical region and the weakening of an alpha1 beta1 contact (1,2). It was first discovered in a single Spanish patient, by protein
More than 80 variants of glucose-6-phosphate dehydrogenase (G6PD) are associated with chronic nonspherocytic haemolytic anaemia (CNSHA); however, the molecular basis of this association is not fully understood. We have used the polymerase chain reaction and nucleotide sequence analysis to
