Abstract
Retardation of growth and development is a well-known late effect after radiotherapy for pediatric patients. The goal of the study was to examine the effect of proton beam therapy (PBT) on the growth of muscles included in the irradiated area. The subjects were 17 pediatric patients (age ≤ 5 years) who received PBT with a treatment field including a muscle on only one side out of a pair of symmetrical bilateral muscles and had imaging evaluations for at least 1 year after PBT. The thicknesses of the irradiated and non-irradiated (contralateral) muscles were measured retrospectively on CT or MRI axial images collected before and after PBT. The change of thickness divided by the period (years) for each muscle was compared between the irradiated and contralateral sides. Correlations of muscle growth with irradiation dose and age at the start of treatment were also evaluated. The median observation period was 39.2 months. The measurement sites included the erector spinae (n = 9), gluteus maximus (n = 5) and rhomboids + trapezius (n = 3) muscles. The average changes in muscle thickness were 0.24 mm/year on the irradiated side and 1.19 mm/year on the contralateral side, showing significantly reduced growth on the irradiated side (P = 0.001). Younger patients had greater muscle growth. Irradiation dose was not significant, but muscle growth tended to decrease as the dose increased, and muscles irradiated at >50 Gy (RBE) showed little growth. These results show that muscle growth is affected by PBT and that long-term follow-up is needed to evaluate muscle growth retardation.

Abstract
The purpose of this study was to analyze renal late effects after proton beam therapy (PBT) for pediatric malignant tumors. A retrospective study was performed in 11 patients under 8 years of age who received PBT between 2013 and 2018. The kidney was exposed in irradiation of the primary lesion in all cases. Kidney volume and contour were measured on CT or MRI. Dose volume was calculated with a treatment-planning system. The median follow-up was 24 months (range, 11-57 months). In irradiated kidneys and control contralateral kidneys, the median volume changes were -5.63 (-20.54 to 7.20) and 5.23 (-2.01 to 16.73) mL/year; and the median % volume changes at 1 year were -8.55% (-47.52 to 15.51%) and 9.53% (-2.13 to 38.78%), respectively. The median relative volume change for irradiated kidneys at 1 year was -16.42% (-52.21 to -4.53%) relative to control kidneys. Kidneys irradiated with doses of 10, 20, 30, 40, and 50 GyE had volume reductions of 0.16%, 0.90%, 1.24%, 2.34%, and 8.2% per irradiated volume, respectively. The larger the irradiated volume, the greater the kidney volume was lost. Volume reduction was much greater in patients aged 4-7 years than in those aged 2-3 years. The results suggest that kidneys exposed to PBT in treatment of pediatric malignant tumor show continuous atrophy in follow-up. The degree of atrophy is increased with a higher radiation dose, greater irradiated volume, and older age. However, with growth and maturation, the contralateral kidney becomes progressively larger and is less affected by radiation.

Abstract
A 22-year-old female with acute myeloid leukemia (AML) in complete remission received a conditioning regimen containing antithymocyte globulin for an unrelated bone marrow transplant (BMT). After BMT, the patient suffered from cytomegalovirus (CMV) pneumonitis with markedly high levels of CMV antigenemia, activated prothrombin time (APTT) prolongation, and subacute thyroiditis. Recovery of CD4+ cells was delayed as long as 1 year after BMT. An association between these three episodes and viral infection due to the delayed recovery of CD4+ cells is suggested.

Abstract
We conducted a pilot study on autologous peripheral blood stem cell transplantation (PBSCT) for 11 adults with B-lineage acute lymphoblastic leukemia (ALL) in first complete remission (CR) or even in those with more advanced stages. All patients achieved CR by induction therapy, of whom 10 were treated with anthracycline, vincristine and prednisolone-based regimens. After consolidation therapy, all patients except one received high-dose cytarabine followed by granulocyte colony-stimulating factor (G-CSF) administration to collect PBSCs. Ten patients received busulfan 4 mg/kg for 4 days, etoposide 20 mg/kg for 3 days and ranimustine 200 mg/m2 for 2 days as a conditioning regimen. One received a regimen consisting of etoposide, cyclophosphamide and total body irradiation. From day 1, G-CSF was given intravenously, and no additional chemotherapy was administered. At the median follow-up time of 30.8 months, four of six patients with standard-risk B-lineage ALL survived within the range of 19.7 to 85.4 months without relapse. In contrast, only one of five with high-risk B-lineage ALL survived for 36.3 months without relapse. Autologous PBSCT as post-remission therapy may prolong CR in adults with standard-risk B-lineage ALL.

Abstract
C-KIT, TIE and HKT expression on leukemic cells from patients were simultaneously analyzed using flow cytometry. Consistent with previous reports, leukemic cells from most patients with de novo acute myeloid leukemia (AML) were C-KIT-positive (28/35), while those from patients with B-lineage acute lymphoid leukemia (B-ALL) were C-KIT-negative (0/9). In the B-ALL patients, leukemic cells trom seven patients had one or more myeloid antigen such as CD13, CD15 and CD33. In contrast to C-KIT expression, leukemic cells from only one patient with acute monocytic leukemia were TIE-positive. Similarly, leukemic cells from only two patients (one, B-ALL with t(4;11)(q21;q23) and one, essential thrombocythemia in myeloblastic transformation (ET-MBT)) were HTK-positive. These results suggest that among the three receptor tyrosine kinases, C-KIT is the most useful marker for identifying AML.

Abstract
In Xenopus oocytes coinjected with poly(A)+ RNA derived from the rat cerebellum and cRNAs for the cloned G protein-gated inwardly rectifying K+ channel (GIRK), GIRK1 and GIRK2, the GABA-B agonist baclofen elicited inwardly rectifying K+ currents. The inward K+ currents elicited by baclofen were inhibited by the selective GABA-B antagonists 2-OH saclofen and CGP 35348, and by the GIRK inhibitor Ba2+. In contrast, baclofen caused no currents in oocytes injected with the cerebellar poly(A)+ RNA alone, the poly(A)+ RNA and cRNA for GIRK1 or GIRK2, or only cRNAs for GIRK1 and GIRK2. These findings indicate that GABA-B receptors in the rat cerebellum were functionally expressed in Xenopus oocytes and activated the cloned GIRKs composed of GIRK1 and GIRK2 as heteromultimers.

Abstract
A retrospective analysis was performed on 76 consecutive elderly patients with acute leukemia aged 60 years or more (48 men, 28 women). Forty patients were 60-69 years old, 28 were 70-79 years old and 8 were > or = 80 years old. There were 55 patients with acute myelogenous leukemia (AML), 13 acute lymphoblastic leukemia (ALL) and 8 AML from myelodysplastic syndrome (MDS/AML). Patients were treated with the JALSG protocol, CAG regimen, or low-dose Ara-C regimen for AML, and DVP/M-CHOP protocol for ALL. The complete remission (CR) rates were 52.7% (29 of 55) in AML, 61.5% (8 of 13) in ALL, and 0% in MDS/AML. The median CR durations were 226, 85, 0 days, and the median survivals were 204, 177, 99 days, respectively. CR rates were 65.3% for the JALSG protocol, 62.5% for the CAG regimen and 25.0% for low-dose Ara-C regimen. According to age, CR was obtained 62.5% in patients aged 60-69 years and 33.3% in patients over 70 years old. Our results indicated that patients aged 60-69 years should be treated with intensive chemotherapy.

Abstract
A 27-year-old female was diagnosed as having atypical aplastic anemia in 1979 because of hypercellular bone marrow with abnormal erythroblasts and megakaryocytes. Afterward the diagnosis was corrected to myelodysplastic syndrome (RA) due to the reevaluation of the bone marrow smears. In March, 1995, thirst and polyurea occurred. In April, 1995, bone marrow aspiration biopsy showed the proliferation of atypical blasts (28%), and two months later, the number of the blasts increased (30%) and leukemic progression was noticed. Only 0.5 percent of the blasts showed weak peroxidase activity, and most of the blasts had CD13, CD33 and several adhesion molecules as CD11a, CD11b, CD44, CD54 and CD56. Karyotype of the bone marrow cells was 45, XX, -7. Her polyurea was caused by central diabetes insipidus. She was also complicated by pleuritis, colon ulcer, sinusitis and hypothalamic dysfunction. The etiology of these signs was due to the leukemic cell infiltration. She died despite of receiving multi-drug chemotherapy.

Abstract
A 44-year-old Japanese man having aplastic anemia (AA)-paroxyamal nocturnal hemoglobinuria (PNH) syndrome was referred to our hospital because of purpuras due to thrombocytopenia in July 1994. He suffered from pneumonia after admission, complicated with cerebral, splenic, and left renal infarction. Pulmonary infaction was also confirmed by perfusion lung scan. He had a plasma plasminogen (PLG) functional activity of 54.4% with a normal level of PLG antigen. The gel isoelectrofocusing pattern of the plasminogen derived from the patient showed 10 normal bands and 10 additional doublet bands with slightly higher isoelectric points than the normal components. Abnormal PLG is converted by urokinase to an inactive two-chain plasmin molecule. These findings were similar to those of a case with dysplasminogenemia (PLG Tochigi) reported by Aoki et al. He was given warfarin for the prevention of thrombosis in December 1994. As of October 1995, these was no recurrence of thrombosis. The cause of thrombosis in the present case have been the association with PNH, predisposition to PLG Tochigi, or the complication of pneumonia. This is the first report of AA/PNH syndrome associated with dysplasminogenemia.
