[A case of malignant lymphoma successfully diagnosed using Sasada transbronchial angled biopsy forceps].

A 68-year-old man was referred to our hospital due to general fatigue, fever and weight loss. His chest radiograph showed a nodule (2.8 cm) in the right middle lobe.

Hb Nishinomiya [Leu-Gly-inserted between codons 69(E13) and 70(E14) of beta]: a novel unstable hemoglobin with reduced oxygen affinity found in a patient with spherocytic hemolysis.

Substantially decreased oxygen saturation levels were incidentally detected by pulseoxymetry in a patient with spherocytic hemolysis who was undergoing laparoscopic splenectomy. Molecular analysis revealed that he was carrying hemoglobin (Hb) Nishinomiya, a novel Hb variant [Leu-Gly-inserted between codons 69(E13) and 70(E14) of beta]. Amino acid substitutions around positions 70-73(E13-17) of the beta chain are likely to change stability and oxygen affinity, as has been demonstrated in several Hb variants including Hb Seattle.

Successful treatment of relapsed T-cell non-Hodgkin's lymphoma with allogeneic peripheral blood stem cell transplantation with double conditioning.

We report a patient with T-cell non-Hodgkin's lymphoma (NHL) who relapsed after treatment with relatively intensive third-generation chemotherapy, VACOP-B, and who was safely and effectively treated with allogeneic peripheral blood stem cell transplantation (allo PBSCT) with double conditioning. The first conditioning consisted of carboplatin and etoposide. Twenty-one days later, the second conditioning was performed with cytosine arabinoside, cyclophosphamide, and total body irradiation (AraC/Cy/TBI).

High incidence of chemotherapy-induced acral erythema in female patients with non-Hodgkin's lymphoma treated with the VACOP-B regimen.

Seven patients, all females out of 29 with non-Hodgkin's lymphoma (NHL) (16 males and 13 females) treated with the VACOP-B regimen utilizing granulocyte-colony-stimulating factor (G-CSF) support developed chemotherapy-induced acral erythema (CAE). In contrast, none of 32 patients with NHL who were treated with CHOP, MACOP-B, or biweekly CHOP regimens without G-CSF developed CAE. Total dose intensities of VACOP-B regimen were higher than those of the three other regimens.

Absence of fetal liver hematopoiesis in mice deficient in transcriptional coactivator core binding factor beta.

Core binding factor beta (CBF beta) is considered to be a transcriptional coactivator that dimerizes with transcription factors core binding factor alpha 1 (CBFA1), -2, and -3, and enhances DNA binding capacity of these transcription factors. CBF beta and CBFA2, which is also called acute myeloid leukemia 1 gene, are frequently involved in chromosomal translocations in human leukemia. To elucidate the function of CBF beta, mice carrying a mutation in the Cbfb locus were generated.

[The analysis of leukemic relapse after allogeneic bone marrow transplantation].

This report presents the analysis of leukemic relapse of 52 patients who received allogeneic bone marrow transplantation between July 1984 and May 1990. Conditioning regimen consisted of TBI + CY and GVHD prophylaxis consisted of cyclosporin-A and methotrexate. The relapse ratios of chronic myelogenous leukemia (CML) (21 in chronic phase, 1 in accelerated phase, 1 in blastic crisis), acute nonlymphocytic leukemia (ANLL) (all 17 in 1st CR), acute lymphocytic leukemia (ALL) (all 12 in 1st CR) were 13%, 18%, 25%, respectively, and 3 year disease free survival (DFS) was as follows, CML 68%, ANLL 72%, ALL 49%.

Clinical effect of granulocyte colony-stimulating factor on neutrophils and leukemic cells in myelogenous leukemia: analysis.

Clinical experiences with recombinant granulocyte colony-stimulating factor (rhG-CSF) in 13 acute (AML) and four chronic (CML) myelogenous leukemia patients are reported. Sixteen patients received rhG-CSF in support of treatment for life threatening infections and one CML patient in support of induction chemotherapy. After their first induction chemotherapy, six out of eight AML patients showed a rapid increase of neutrophils, recovered from infections and achieved complete remission (CR).

[A case of CA19-9 producing adenocarcinoma of the lung associated with idiopathic interstitial pneumonia].

A 63-year-old female, who had been suffering from idiopathic interstitial pneumonia (IIP) since two years and four months previously, was admitted with general fatigue, body weight loss, bloody sputum and progression of dyspnea. Chest roentgenogram on admission showed diffuse coarse ring shadows in the right middle and lower lung fields and in the left middle lung filed. Chest CT clearly showed honeycombing in bilateral dorso-basal segments of the lung.
