Molecular makers such as thrombin-antithrombin complex (TAT), prothrombin fragment 1+2 (F1+2), soluble fibrin (SF), and D-dimer, are useful markers in the diagnosis and assessment of various thrombotic conditions. These markers are measured in plasma after blood sampling. Difficult blood sampling is known to falsely elevate plasma TAT levels. However, it is(More)
A 43-year-old patient with rice-induced bronchial asthma was first admitted to our hospital for developing bronchial asthma induced by mite and house dust. At that time, there was no sign of allergic response to rice. Two years later, he was readmitted in an emergency state, with a severe attack of bronchial asthma. This time, however, the result of(More)
Patients with unresectable non-small-cell lung cancer (NSCLC) usually have undergone chemotherapy; however, such problems as resistance to chemotherapeutic agents occur during the treatments. Recent studies have indicated that glutathione S-transferase-pi (GST-pi) may play an important role in the resistance of cancer cells to alkylating agents, including(More)
OBJECTIVES Some patients with myelodysplastic syndrome (MDS) show a marked increase in the percentage of immature platelet fraction (IPF%) despite the absence of severe thrombocytopenia. To determine the significance of such an unbalanced increase in the IPF%, we investigated the IPF% and other laboratory findings of 51 patients recently diagnosed with MDS.(More)
Telomerase is a ribonucleoprotein that synthesizes telometric DNA on chromosome ends, and may be related to the aging and immortality of cells. Recently, a telometric repeat amplification protocol (TRAP) assay for telomerase activity, using the polymerase chain reaction, was developed. We examined the limitations of TRAP assay by applying it to a cultured(More)
We describe a 35-year-old woman with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) who received allogeneic sibling donor peripheral blood stem cell transplantation (PBSCT) and entered a second complete remission. Upon detection of BCR-ABL transcripts after PBSCT, the patient received imatinib, leading to molecular remission.(More)
Two patients with advanced renal cell carcinoma underwent allogeneic hematopoietic stem cell transplantation and received cyclosporine (CSP) as part of their immunosuppressive therapy. Despite adequate renal function, both patients developed hyperkalemia. CSP was the only pharmaceutical agent to which this electrolyte abnormality could be attributed.(More)
We examined a 63-year-old female, who was referred to our hospital for a thorough examination of abnormal findings on the X-ray which were first detected in May, 1992, and suggested a tumor. After hospital admission, a bracheobronchial lymph node biopsy was performed, and the results suggested a pseudo-lymphoma. However, because the possibility of a(More)
