Increased numbers of bone marrow mast cells were found in 45 (2.2%) of 2,000 bone marrow specimens obtained from patients who had hematologic disorders. Mast cells were most frequently seen in the marrows of patients who had preleukemic syndromes, lymphoproliferative disorders, and acute leukemia. The 16 patients who had preleukemic syndromes included those with refractory sideroblastic and megaloblastic anemia (with or without an excess of blasts), idiopathic pancytopenia or pure erythrocytic aplasia, paroxysmal nocturnal hemoglobinuria, idiopathic refractory neutropenia, agranulocytosis or thrombocytopenia, and persistent eosinophilia. Five of the seven patients who had acute leukemia had nonlymphoblastic leukemia; two had blastic crisis of chronic granulocytic leukemia. Of the 13 patients who had lymphoproliferative disorders, eight had chronic lymphocytic leukemia, three had macroglobulinemia, and two had non-Hodgkin's lymphoma. Three patients who had chronic renal failure associated with severe anemia and two who had chronic liver disease, splenomegaly, or hypersplenism were also encountered. In this study there appeared to be a consistent relationship between the presence of increased numbers of mast cells and the lymphocyte and plasma cell counts in the bone marrow. The significance of the presence of secondary mastocytosis in premalignant lesions, neoplasia, and, in particular, lympho- and myeloproliferative disorders, is still unclear.

A novel 16,23-epoxy-5 beta-cholestane triglycoside (1) was isolated from the bulbs of Ornithogalum saundersiae (Liliaceae). The structure was determined by extensive spectroscopic analysis. The conformation of the E-ring part of 1 was studied through molecular mechanics and molecular dynamics calculation methods. Compound 1 potently inhibited proliferation of peripheral blood lymphocytes provided from a chronic renal failure patient without causing any cytotoxicity in the lymphocytes and HL-60 human leukemia cells.

We report here a case of acute lymphoblastic leukemia (ALL) which occurred in a 34-year-old female with chronic renal failure (CRF). Although she was placed on chronic hemodialysis therapy (HD), she achieved complete remission (CR) with the use of chemotherapy. Our therapeutic regime was as follows. 1. The full dose of the Japan adult leukemia study group (JALSG)-ALL90 protocol was given and consisted of vincristine, cyclophosphamide, doxorubicin, mitoxantrone and predonisolone at the stage of CRF (serum creatinine concentration equal to/or less than 5.6 mg/dl). 2. The full dose of etoposide and 80% dose of cyclophosphamide, aclarubicin and vindesine used for consolidation therapy may be toxic when they are given after HD. 3. The dose of Enocitabine should be divided in every 12h in the context of toxicity to bone marrow and the mechanism of action. In conclusion, to induce remission in the case of acute lymphoblastic leukemia, we suggest that it is possible to give 80% to a full dose of JALSG-ALL90 protocol, despite the complication of CRF or HD.

We report five cases of cytomegalovirus infection in immunocompromised patients which were detected by either cytomegalovirus antigenemia assay or in situ hybridization. Four cases had leukemia and the other had chronic renal failure. All the three BMT recipients suffered from GvHD. Interestingly, there was an unique case of CMV disease without a history of BMT, which reminded us that CMV could attack immunocompromised patients who had not undergone transplantation, too. Four out of five cases died. We think that cytomegalovirus infection or disease should not be regarded as a minor problem in post-transplantation infection in Korea.

Eleven patients with chronic subdural hematoma (CSDH) with bleeding tendency (BT) were surgically treated in the last 12 years. To study the clinical problem of CSDH with BT, 11 surgical cases were divided into 3 groups, Group A; CSDH with primary BT (1 case of hemophilia A), Group B; CSDH with BT secondary to a basic disease (3 cases of leukemia, 2 cases of malignant tumor with DIC, 1 case of chronic renal failure and 1 case of liver cirrhosis), Group C; CSDH with BT by anticoagulants (warfarin) (2 cases of replacement of mitral valve, 1 case of A-C bypass). Evacuation of the hematoma was performed by means of one or two burr holes with irrigation of the hematoma cavity and a drainage tube was placed in the subdural space. The outcome was excellent in Groups A and C. In Group B, two patients with DIC due to gastric cancer and prostatic cancer died, and 3 patients with leukemia recovered dramatically from CSDH, but the poor course of the disease itself resulted in death. The outcome of other patients in Group B was excellent. Since CSDH with BT is often fatal, those patient had usually been treated conservatively. However, from this analysis, we stress that CSDH with BT should be surgically treated after checking the blood conditions carefully to determine whether or not the patient has need for surgery.

Pathologies of serial sections of 9 temporal bones from 6 patients without caloric response were studied. The patients died of epipharyngeal cancer, middle ear cancer, chronic renal failure with DIC, pancreatic cancer with DIC, multiple brain metastasis of pancreatic cancer, and leukemia. Under light microscopy, 8 ears showed pathologies in the vestibular end organs and the nerves. Possible causes of the lack of caloric responses in the 8 ears were endolymphatic hemorrhage, labyrinthitis, leukemic infiltration in the labyrinth, degeneration or disappearance of the vestibular sensory cells, reduction in the number of vestibular nerve fibers, and/or brainstem lesions. The remaining one ear did not show abnormal findings in the vestibular end organs or the nerves, but the patient had brainstem lesions. Four types of temporal bone pathologies were observed according to the lesion site responsible for the lack of caloric response; i) sensory type, ii) neural type, iii) mixed type and iv) central type.

Cytokines are multifunctional signaling peptide molecules which regulate a plethora of cellular activities in the immune system. Cytokines provide a means of communication between the immune system and its non-immune neighbours. Several clinical entities have been recognized as targets for clinical applications including interaction with malignant cell growth, host defence against infectious agents, negative regulation of autoagressive disorders and regulation of tissue and cell regeneration. Interferon-alpha (IFN-alpha) can effectively regulate malignant growth in hairy-cell leukaemia, the first example of a biological treatment modality which tames a malignant disease and noramlizes life expectancy, although cure is not achieved. INF-alpha can also control myeloid hyperplasia in approximately two-thirds of the patients with chronic myelogenous leukaemia. In 30% of the patients, treatment is accompanied by partial or complete restoration of normal haematopoiesis. Such cytogentic responses have not been observed with conventional chemotherapy. INF-alpha is also effective in infectious viral hepatitis B, C and D. A long-term beneficial response is observed in 25-40% of the patients. Promising results have also been seen with INF-gamma and interleukin-2 for the treatment of chronic leishmania infection and lepromatous leprosy. Activation of monocytes or macrophages induces these cells to intracellularly destruct leishmania parasites. Growth factors have been identified which influence erythrocyte, granulocyte and macrophage production. Their clinical use has been studied in patients with bone marrow failure, chronic renal failure, acquired immunodeficiency syndrome and in patients with cancer undergoing chemotherapy or bone marrow transplantation. Additional work is needed to appreciate the immunnodulation effect of cytokines and their role in wound healing and tissue regulation.

Adult T cell leukaemia-lymphoma (ATL) was first discovered and reported in Japan, where it has a high incidence in the south-west region. The first human retrovirus HTLV-I (human T-cell lymphotropic virus type I) is considered to be related to its aetiology. In ATL endemic areas, HTLV-I carriers form a fairly high percentage of the population, even among healthy individuals. ATL shows diverse clinical features. It can be divided into four subtypes: acute, chronic, smouldering and lymphoma type. ATL cells originate from the CD4-positive subset of peripheral T cells; they show a characteristic notch in the nucleus and a tendency to lobulation. ATL resists chemotherapy, and patients with acute and lymphoma types have a fairly poor prognosis. A definite diagnosis of ATL is made by documenting the presence of HTLV-I proviral DNA in the DNA of tumour cells. HTLV-I infection is caused by transmission of live lymphocytes via three routes (from mother to child, from males to females, and by transfusion). Familial occurrence of ATL is frequently seen. HTLV-I infection is seen in other countries, but its incidence is highest in Japan. Infection with HTLV-I is a direct cause of ATL. Furthermore, infection with this virus can indirectly cause many other diseases via the induction of immunodeficiency, such as chronic lung disease, opportunistic lung infection, cancer of other organs, monoclonal gammopathy, chronic renal failure, strongyloidiasis, non-specific dermatomycosis, HTLV-I-associated lymphadenitis, HTLV-I uveitis and HTLV-I-associated myelopathy-tropical spastic paraparesis (HAM/TSP).

Mucormycosis is an opportunistic fungal infection that commonly begins by invading the respiratory tract. The purpose of the present study was to define the clinical presentation of pulmonary mucormycosis and to evaluate current treatment regimens. Thirty patients treated at our institution and 225 cases reported in the literature were reviewed. For the combined groups, the mean age at presentation was 41 +/- 21 years and associated medical conditions included leukemia or lymphoma (37%), diabetes mellitus (32%), chronic renal failure (18%), history of organ transplantation (7.6%), or a known solid tumor (5.6%). The in-hospital mortality was 65% for patients with isolated pulmonary mucormycosis, 96% for those with disseminated disease, and 80% overall. The mortality in patients treated surgically was 11%, significantly lower than the 68% mortality in those treated medically (p = 0.0004). The most common causes of death were fungal sepsis (42%), respiratory insufficiency (27%), and hemoptysis (13%). Pulmonary mucormycosis has a high mortality; however, antifungal agents appear to improve survival. In addition, surgical resection may provide additional benefit to patients with pulmonary mucormycosis confined to one lung.
