摘要:

A 12-year-old male of Chinese ancestry had life-long hemolytic anemia attributed to α-thalassemia. Restriction endonuclease mapping of his DNA revealed that in reality, he had three α-globin loci, but he was homozygous for pyruvate kinase deficiency. The new pyruvate kinase variant carried by this patient was characterized and designated PK Fukie

摘要:

The concentration of total glutathione (GSH + GSSG) and its depletion during oxidant stress were studied in neutrophils obtained from human neonates, their mothers and adult controls to determine if the previously reported increased susceptibility of infant neutrophils to oxidant damage could be related to glutathione deficiency. We found the basal level of glutathione to be lower and the oxidant-induced depletion of glutathione to be greater in infant neutrophils than in cells obtained from the blood of the infants’ mothers and adult controls. In studies reported earlier, neutrophils from infants were found to be deficient in the oxidant protective enzymes glutathione peroxidase and catalase. These abnormalities, in a fashion similar to that observed for patients with congenital defects of glutathione and catalase metabolism, may render infant neutrophils prone to oxidant damage and consequent dysfunctio

摘要:

HbA1 was determined in 15 G-6-PD-deficient subjects during a hemolytic crisis with hemoglobinuria due to ingestion of fresh fava beans. The same G-6-PD-deficient subjects were studied again 4 months after the crisis, when they were asymptomatic. 15 normal healthy children served as controls. A statistically significant decrease in HbA1 was observed in the favic subjects during hemolytic crises compared with their values 4 months later and those of the control group.

摘要:

We report a case of autoimmune hemolytic anemia, in a 28-year-old man with a warm-reacting IgG antibody with anti-Sdx activity. The unusual characteristics of the patient included the dramatic response to steroids and relapse after 1 year of treatment. This likely reflects the presence of an underlying autoimmune abnormality.

摘要:

We present here a case of chronic lymphocytic leukemia in association with both IgM kappa and IgM lambda gammopathy with apparent distinct localization. Detailed case presentation is included and discussion of the immunologic and clinical implications follows.

摘要:

In 83 children with acute lymphoblastic leukaemia (ALL) the immunological phenotype of the lymphoblasts was determined using E rosetting, monoclonal anti-T cell sera, surface immunoglobulin staining and common ALL antiserum. The data were compared with acid alpha-naphthyl acetate esterase (ANAE) and acid phosphatase (AP) cytochemical data. The vast majority of T-ALL cells proved to be ANAE-negative (30/31) and AP-positive (29/31). Null-ALL was always AP-negative (12/12), the ANAE reaction was sometimes positive (4/12). In common ALL, findings ranged from negative to positive for both enzymes. Two cases of B-ALL were ANAE-negative and AP-negative. Enzyme cytochemical determinations gave thus preferential patterns, especially for T-ALL and null-ALL. In common ALL, considerable heterogeneity was found, which may be a reflection of differences in maturation between different cases of common ALL.

摘要:

39 patients suffering from different subtypes of monocytic (M 5) and myelomonocytic (M 4) leukemia were analyzed retrospectively. In 8 cases a ‘transitional myelomonocytic variant’ was diagnosed; the leukemic cell in these patients is marked by morphological and cytochemical signs of monocytic and granulocytic precursors. As the correct diagnosis of this special subtype may be difficult, its place within the French-American-British (FAB) classification will be discus

摘要:

The construction of an artificial circulation for the study of thrombolysis allowing variation in fluid pressure and flow rate is described. The lysis of 125I-fibrin was not influenced by variation in pressure between 10 and 30 cm H2O, but was significantly faster at a flow rate of 25 ml/min than at 40 ml/min or 10 ml/min. At equivalent concentrations as assessed on fibrin plates tissue activator induced greater thrombolysis than urokinase. Thrombolysis by both activators was diminished in the presence of plasma.
