Abstract
Abstract
Spindle cell lipoma (SCL) is a subtype of lipoma first defined by Enzinger; it accounts for ~1.5% of all fatty tumors. Most cases occur in the posterior neck and shoulders of middle-aged men and rarely in women or the occiput. A 41-year-old woman presented to us with complaints of a mass on her left occiput which had slowly grown in size over six years. We excised the tumor, and pathological findings confirmed the diagnosis of SCL. There was no recurrence one year after the surgery.

Abstract
The T cell-lineage marker CD2 is sometimes expressed in acute promyelocytic leukemia (APL), and CD2 expression is reported to correlate with some clinical characteristics. However, the significance of CD2 expression in APL has not been fully elucidated. We evaluated CD2 expression in APL treated by the same treatment strategy in a single institute, and whether it had any special characteristics. Among 29 APL, 6 were positive for CD2. Patients with CD2+ APL tended to have a higher leukocyte count than CD2- APL (34.5 +/- 13.1/l vs. 6.8 +/- 2.1/l), morphological characteristics as variant-APL (50 vs. 0%). They also showed poor clinical prognosis. The CR rate of CD2- APL was 87.0% while that of CD2+ APL was 50 %. The mortality was 13.0 and 66.7%, respectively, and the survival rate was significantly lower in CD2+ APL. CD2 expression was proven to be a risk factor associated with death in addition to the morphological characteristics of variant-APL and leukocytosis. These results indicated that CD2 expression might have a significant impact on the prognosis of APL. Whether CD2+ APL should be characterized as a special clinical entity should be discussed in a larger patient population.

Abstract
Activation of Na(+)/H(+) exchanger (NHE) may have an important role in the ischemia/reperfusion injury by producing intracellular calcium overload. Recent studies have shown a beneficial effect of an NHE inhibitor on the ischemia/reperfusion injury in the heart. In this study, we examined the effect of FR183998, a potent NHE inhibitor, in porcine pancreas allotransplantation from non-heart-beating Landrace pig donors (NHBDs). The four experimental groups included: untreated with no preservation (group 1; n = 3), treated with no preservation (group 2; n = 5), untreated with preservation (group 3; n = 6), and treated with preservation (group 4; n = 4). The preservation was made in ice-cold University of Wisconsin (UW) solution for 24 hours. The groups treated received 1 mg/kg FR183998 before donor cardiac arrest and 10 mg in the UW solution flush in situ. Serum blood glucose, insulin, and amylase were measured daily. An intravenous glucose tolerance test (IVGTT) was performed on the postoperative day (POD) 7 when pigs were sacrificed for histological examination. Graft survival rates on that day in groups 1,2,3, and 4 were 3 of 3; 5 of 5; 3 of 6; and 4 of 4, respectively. The mean K values of IVGTT in groups 3 and 4 were 0.78 +/- 0.10 and 1.27 +/- 0.16, respectively, which were significantly different (P < .05). Upon histological examination, pancreatic tissue in group 3 showed more severe edema and necrosis than other groups. FR183998 may be considered beneficial for ischemia/reperfusion injury to pancreatic grafts from NHBDs.

Abstract
We investigated the effects of portocaval shunt (PCS) on excessive portal flow in producing sinusoidal microcirculatory injury in small-for-size liver transplants in pigs. The posterior segment of a whole liver (25%) was transplanted orthotopically. The pigs were divided two groups: group A, graft with PCS (n = 11), and group B, graft without PCS (n = 11). The PCS was a side-to-side anastomosis of the portal vein and the inferior vena cava. In group A, eight pigs survived for more than 4 days; all pigs except for one died of graft nonfunction within 24 hours in group B. The portal flow after reperfusion decreased in group A, but increased about three times greater in group B than that before the operation (P < .01). In group B, destruction of the sinusoidal lining and bleeding in the periportal areas were observed after reperfusion, findings that were not recognized in group A. These results suggest that graft nonfunction after small-for-size liver transplantation may be attributable to excessive portal flow producing sinusoidal microcirculatory injury.

Abstract
There are only a few studies of the relationship between hemostatic abnormalities and intraarterial pressure, so the present study investigated the association of various newer lipid and hemostatic variables with intraarterial pressure levels. Levels of total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, triglyceride, lipoprotein-(a), remnant-like particle cholesterol, cholesteryl ester transfer protein, uric acid, blood glucose, fibrinogen, free form of tissue factor pathway inhibitor (TFPI), C-reactive protein, serum amyloid A protein, anti-Chlamydia pneumoniae immunoglobulin G and immunoglobulin A, and apolipoproteins (apo) A-I, B, and E were measured in 176 patients who underwent diagnostic coronary angiography. Intraarterial blood pressure was determined from central aortic pressure using a standard fluid-filled catheter-external transducer system. Multivariate regression analyses showed that TFPI level was the only independent factor associated with aortic diastolic pressure. The linear regression equation demonstrated a significant negative correlation of TFPI level with aortic diastolic pressure (r=-0.395, p=0.0011). With respect to the association with other parameters, the TFPI level showed significant correlations between the HDL-C level and the apo A-I level, both in the overall patients and in the patients with coronary artery stenosis. This is the first evidence that the level of the plasma free form of TFPI is inversely correlated to aortic diastolic pressure.

Abstract
A 45-year-old woman was referred to our hospital because of hyperthyroidism complicated by atrial fibrillation and heart failure. Laboratory data revealed pancytopenia, with a white blood cell count of 2,600/microliter, red blood cell count of 330 x 10(4)/microliter, and platelet count of 6.2 x 10(4)/microliter. The patient had normal transaminase levels, but tests for hepaplastin and cholinesterase showed values of 34% and 1.4 U/ml, respectively, indicating liver dysfunction. There was also decreased excretion of indocyanine green. After initiation of treatment with 30 mg thiamazole and 20 mg propranolol daily, the patient's thyroid function normalized and the other abnormal laboratory findings such as pancytopenia and liver dysfunction also disappeared. Pancytopenia is a rare complication of hyperthyroidism. In this case, various laboratory abnormalities were normalized by antithyroid therapy alone, indicating that the hyperthyroidism itself was closely related to the pathogenesis of pancytopenia and liver dysfunction.

Abstract
A 55-year-old Jehova's Witness was treated for acute myelogenous leukemia (AML) by intensive chemotherapy with enocitabine, 6-mercaptopurine and daunorubicin. G-CSF, M-CSF and EPO were subsequently administered. Even though no blood transfusion was given for religious reasons, complete remission was achieved without serious infection and hemorrhage. The total cost for induction chemotherapy was less expensive than is the case for elderly AML patients. This case indicates that the administration of cytokines might reduce the incidence of infection and the necessity for blood products, which would result in favorable cost effectiveness for the treatment of elderly patients with AML.

Abstract
OBJECTIVE We designed the present study to evaluate the association of various lipid and fibrinolytic components with coronary artery stenosis with respect to the triglyceride (TG) level. METHODS Levels of TG, remnant-like particle cholesterol (RLP-C), total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), lipoprotein-(a), uric acid, blood glucose, tissue plasminogen activator (t-PA), t-PA inhibitor type 1, antithrombin III, and protein C were measured in 208 patients who underwent diagnostic coronary angiograms. PATIENTS Of these 208 patients, 59 were hypertriglyceridemic (150 mg/dl or higher) and 149 were normotriglyceridemic. RESULTS Both LDL-C and HDL-C showed significant differences between patients with and those without coronary artery stenosis in both hypertriglyceridemic and normotriglyceridemic patient subgroups. However, RLP-C showed a significant difference in the normotriglyceridemic patient subgroup (p=0.012) but not in the hypertriglyceridemic patient subgroup (p=0.736). CONCLUSION Our current retrospective study disclosed that RLP-C levels are closely associated with coronary artery stenosis in patients with normal TG levels.

Abstract
BACKGROUND Limited information is available as to whether there is a difference in the association of lipid and fibrinolytic variables with coronary artery disease according to the presence or absence of elevated serum total cholesterol. We examined the levels of various lipid and fibrinolytic variables including remnant-like particle cholesterol (RLP-C). RLP-C is a recently established simple assay method for the estimation of triglyceride-rich lipoprotein remnants. METHODS AND RESULTS Levels of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), triglyceride, lipoprotein(a), RLP-C, uric acid, blood glucose, tissue plasminogen activator, tissue plasminogen activator inhibitor type 1, antithrombin III, and protein C were measured in 208 patients who underwent diagnostic coronary angiograms. Of these 208 patients, 57 were hypercholesterolemic (> or =220 mg/dL) and 151 were normocholesterolemic. HDL-C showed significant differences between patients with and those without angiographically determined coronary artery stenosis in both hypercholesterolemic and normocholesterolemic patients (P =.0025 and P =.0003, respectively). Both RLP-C and uric acid showed significant differences only in the normocholesterolemic subgroup (P =.0006 and P =.0060, respectively). This difference in uric acid was not significant by multivariable analysis. The ratio of RLP-C/HDL-C was demonstrated to be highly significantly (P <.0001) associated with coronary artery stenosis in patients with normal total cholesterol, whereas there was no statistically significant association in the hypercholesterolemic patient subgroup. CONCLUSIONS Our current study disclosed that RLP-C levels are strongly associated with coronary artery disease, especially in patients with normal total cholesterol levels. Moreover, RLP-C/HDL-C ratio may be even more significantly associated with the presence of coronary artery stenosis in normocholesterolemic patients.

Abstract
A 60-year-old woman was admitted to our hospital in February 1993 due to dizziness, dyspnea, abdominal pain, and high susceptibility to bleeding. Physical examination revealed livedo reticularis of the foot, but did not detect hepatosplenomegaly. Examination of the peripheral blood detected pancytopenia, leukoerythroblastosis, and tear-drop erythrocytes. Primary myelofibrosis (PMF) was diagnosed on the basis of bone marrow biopsy findings. Antiphospholipid syndrome (APS) was confirmed by positive response to anti-cardiolipin antibody and recurrent splenic infarction. Because of factor XIII deficiency, the patient experienced severe gingival bleeding after tooth extraction. Her condition was complicated by mesenteric arterial thromboembolism and she died of sepsis 5 years after onset. Although the incidence of immunopathy in PMF patients is high, few studies to date have focused on APS patients presenting with a variety of severe embolic symptoms. Our patient required careful monitoring due to bleeding tendency and thromboemboli.

Abstract
There is an increasing incidence of the evolution of myelodysplastic syndrome (MDS) from aplastic anaemia (AA) with immunosuppressive treatment. In paediatric patients G-CSF is also reported to increase MDS evolution, but this process is not precisely understood in children or in adults. Therefore risk factors of MDS evolution in adults are evaluated here. Of 72 patients, five developed MDS. In 47 patients without cyclosporine (CyA) or antithymocyte globulin (ATG) therapy, only one developed MDS with trisomy 8, 242 months after diagnosis. But of 25 patients treated with either CyA or ATG, four developed monosomy 7 MDS within 3 years. Of these 25 patients, 18 were treated with G-CSF and the four patients (22.2%) who developed MDS were found in this group. The cumulative dose and the duration of G-CSF administration were significantly elevated in patients who developed MDS when compared with those who did not, 822.3 +/- 185.0 v 205.4 +/- 25.5 microg/kg (P<0.05) and 187.5 +/- 52.5 v 72.0 +/- 24.6 d (P<0.002), respectively. However these two values for CyA did not differ significantly. Statistically, treatment with CyA, G-CSF and combined G-CSF and CyA were significantly related to MDS evolution. The administration of G-CSF for more than a year was the most important factor (P=0.00). These results suggested that a close relationship exists between G-CSF and subsequent monosomy 7 MDS from AA in adults who receive immunosuppressive therapy. Long-term administration of G-CSF should be prohibited in order to prevent MDS evolution.

Abstract
BACKGROUND There is as yet no definite consensus on the predictive value of the various lipid profiles and fibrinolytic parameters that became available in clinical use recently for coronary artery disease. METHODS Levels of lipoprotein(a), high-density lipoprotein cholesterol (HDL-C), remnant-like particles cholesterol (RLP-C), tissue plasminogen activator (TPA), TPA inhibitor, antithrombin III, and protein C were measured in 124 patients who underwent diagnostic coronary angiograms. RESULTS Of these patients, 37 had no significant stenoses (group N) and 87 had significant stenoses (group S). There were no significant differences in patient characteristics between the two groups. HDL-C was significantly lower (p = 0.0071 ) and RLP-C was significantly higher (p = 0.0022) in group S. When a product and a ratio of each of two factors were calculated, RLP-C/HDL-C was demonstrated to be a highly significant predictor for coronary artery stenoses (p < 0.0001). There were also significant increases in RLP-C/HDL-C levels with increasing number of vessels involved (r = 0.359, p < 0.0001 ). CONCLUSION Our present study disclosed the predictive value of RLP-C/HDL-C ratio as a new indicator of coronary artery disease.

Abstract
An 80-year-old woman was referred to our hospital because of irregular genital bleeding. An abnormal mass was found in the uterine cervix, and diagnosed as non-Hodgkin's lymphoma, diffuse large B cell type. Soon after admission, the patient became anuric and was given a diagnosis of acute renal failure due to obstruction of the ureter. She was immediately placed on dose-reduced CHOP and radiotherapy of 15 Gy. As a result, not only did the malignant lymphoma go into remission, but diminished renal function was alleviated. Because malignant lymphoma of the uterus is extremely rare, it exact biocharacteristics are not well understood. We are unaware of any previous report concerning uterine lymphoma complicated by renal failure.

Abstract
An extremely unusual case of gastric outlet syndrome, otherwise known as Bouveret's syndrome, caused by a large gallstone impacted in the duodenum due to a cholecystoduodenal fistula (CDF), is described herein. Another large gallstone impacted in the CDF itself was also detected. As endoscopic extraction of the gallstone from the duodenum proved unsuccessful, and a laparotomy was required. Our patient, being 88 years old, is probably the oldest patient recorded in the literature of this syndrome. The methods of establishing a correct diagnosis by endoscopy and recent therapeutic strategies are discussed following the case report.

Abstract
A 55-year-old man had rhabdomyolysis and myocardial damage induced by palytoxin. Weakness and myalgia of four extremities occurred five hours after eating a fish. Rhabdomyolysis developed and the serum creatine phosphokinase (CK) was elevated to 40,000 IU/l on the 3rd day. Gastric lavage with activated charcoal and forced mannitol-alkaline diuresis therapy were performed. The patient recovered with no complication such as renal failure. In this case, palytoxin was suggested to induce myocardial damage which was demonstrated by an elevation of the myosin light chain level and a change in electrocardiogram.

Abstract
The direct causal relationship between dermatomyositis-polymyositis (PM) and malignancy remains controversial. We describe herein the case of a patient who underwent surgical treatment for colon cancer, which had preceded the onset of PM with tumor relapse. The PM markedly improved following the initiation of steroid therapy, and has remained under control, probably as a result of chemotherapy. The current concepts of variable clinical courses and the possible mechanism for the association of PM with malignancy are discussed following this case report.

Abstract
A 74-year-old woman presented with anal bleeding and a protuberant mass. A biopsy of the mass revealed the proliferation of spindle-shaped cells with melanin pigments, and an abdominoperineal resection was performed, the histology of which confirmed malignant melanoma. Surgery was absolutely noncurative because massive metastases were encountered in the pelvic and paraaortic lymph nodes. However, postoperative chemotherapy, composed of decarbazine (DTIC), vincristine (VCR), and nimustine hydrochloride (ACNU), achieved satisfactory results. The patient has been well without any evidence of recurrence for more than 3 years.

Abstract
Hemophagocytic syndrome (HPS) presents with fever, pancytopenia, liver dysfunction and increase in hemophagocytic histiocytes in various organs. Although there are two major classifications of HPS in adults, malignant and reactive histiocytosis, it is often very difficult to distinguish between these disorders. We analyzed the laboratory data of patients with HPS to evaluate prognostic factors. Of 34 patients, 14 survived, and 20 died. The median age of survivors was 29.6+/-11.5 yr significantly younger than those who died (54.7+/-17.8 yr). Twenty patients had no obvious underlying disease, the other 13 had hematological malignancies or viral infections. Comparison of laboratory data revealed that nonsurvivors had significantly lower Hb and platelet values on admission. During treatment, worsening of anemia and thrombocytopenia, increase of transaminase and biliary enzymes were similarly more prominent. Risk factors associated with death were: age over 30 yr, presence of disseminated intravascular coagulation, increased ferritin and beta2-microglobulin, anemia accompanied by thrombocytopenia and jaundice. Our data suggests that patients with HPS and any of these risk factors should be treated aggressively with sufficient chemotherapy and supportive care.

Abstract
Primary extranodal malignant lymphoma frequently occurs in the gastrointestinal tract: however, it is rarely encountered in the rectum. We report herein the case of an 85-year-old man who underwent abdominoperineal resection for primary malignant lymphoma of the rectum, and 1 year later, developed hematemesis caused by gastric metastasis. To our knowledge this is the first case report of such distant metastasis developing from malignant lymphoma of the rectum.

Abstract
Severe anemia A 37 year-old male with therapy resistant multicentric Castleman's disease (MCD) anemia was treated by subcutaneous injection of erythropoietin. Although immunoglobulin and CRP concentration increased, anemia obviously improved with hemoglobin levels increasing from 4.8 g/dl to 8.5 g/dl without any side effects. Colony assay revealed that the bone marrow mononuclear cells responded to erythropoietin in a dose dependent manner. The mechanism of anemia of MCD is not clearly understood, and treatment is sometimes very difficult. There is no other previous report concerning erythropoietin as a treatment for anemia in MCD.

Abstract
Severe aplastic anemia was diagnosed in a 58-year-old female because of pancytopenia with leukocyte count 700/microliters, hemoglobin 3.4 g/dl, platelet count 4.2 x 10(4)/microliters and fatty hypoplastic bone marrow in August 1992. In January 1993, she was admitted with an abdominal skin infection caused by pseudomonas aeruginosa. After treatment of the infection, antilymphocyte globulin was given at a dose of 2,000 mg/day for four consecutive days in July 1993. This resulted in a gradual but steady improvement in her hematological data. In February 1995, her leukocyte count increased to 2,000/microliters, hemoglobin to 15.2 g/dl and platelet count to 11.0 x 10(4)/microliters. Although no splenomegaly or myelofibrosis was found previously, from April 1993, the spleen enlarged and was palpable 10 cm below the costal margin. Her bone marrow biopsy in June 1993 revealed prominent myelofibrosis. Thereafter no changes were found in these features. Splenomegaly and myelofibrosis are characteristic of primary myelofibrosis and although the relationship is uncertain, there is no previous report on aplastic anemia with splenomegaly and myelofibrosis.

Abstract
A 59-year-old man was admitted to our hospital because of fever in August 1991. Bone marrow showed normocellularity with 41.5% of CD13, 14, 33 positive blasts, and a diagnosis of AMMoL was made. Laboratory investigation revealed hyponatremia and elevated serum ADH level, indicating the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Intensive chemotherapy successfully induced hematological complete remission and his serum sodium level became normal. In February 1992, he developed proteinuria and findings were consistent with nephrotic syndrome (NS). Renal biopsy specimen showed membranous proliferative glomerulonephritis and massive infiltration of macrophages, and his serum interleukin 6 level was elevated. Five months later, he suffered from pancytopenia and elevation of biliary enzymes with increase of hemophagocytic histiocytes in his bone marrow (hemophagocytic syndrome). He transiently responded to low dose chemotherapy but he died due to severe infection. It is interesting that association between macrophages and/or cytokines with these various complications was suggested in AMMoL.

Abstract
Ideally, in preoperative intra-arterial infusion chemotherapy (regarding advanced breast cancer) is to obtain the most significant effects concerning histological features. Intra-arterial infusion chemotherapy using epirubicin (EPI), used in conjunction with daily doses of 1,200 mg medroxyprogesterone acetate (MPA), have recently been performed. This procedure has shown remarkable histological effects in the metastatic lymph nodes as well as in the primary lesions. These results were especially remarkable in the patients who were administered MPA (daily) two weeks prior to EPI infusion. These patients showed a complete disappearance of tumor cells. The results were interesting in view of the mechanism of action. Intra-arterial infusion chemotherapy combined with MPA may also be valuable in treating metastatic liver tumors and recurrent lesions in the regional lymph nodes such as supraclavicular tumors. A high response rate was obtained in the chemo-endocrine therapy when combined with MPA as a pretreatment. Thus, MPA may be expected to be available as a systemic therapy, too. In the future, a new development in the field of intra-arterial infusion chemotherapy may be achieved by utilizing a combination of angiogenesis inhibitors and peripheral blood stem cell transplantation.

Abstract
A case with autoimmune hemolytic anemia (AIHA) induced by interferon-alpha (IFN-alpha) is presented. A 40-year-old male who had a previous history of autoimmune hemolytic anemia, agranulocytosis and thrombocytopenia was admitted to our hospital because of chronic C type hepatitis. Liver biopsy was performed, which diagnosed chronic active hepatitis and IFN-alpha was administrated at a dose of 3 Meg unit per day. 11 days after the initiation of the therapy he developed hemolytic anemia, but Coombs tests were negative. Although IFN was withdrawn 15 days later, anemia became progressively more serious. 20 days later, both direct and indirect Coombs tests became positive. He was diagnosed as AIHA and treated with methylprednisolone pulse therapy, then he recovered soon afterward. Further analysis of Coombs tests revealed that he had both cold type and warm type (IgG) autoantibodies which was the same type of antibodies for AIHA he suffered 10 years ago. In conclusion, latent AIHA may be reactivated by the treatment with IFN-alpha.

Abstract
A 19-year-old male who suffered from severe aplastic anemia had been treated with granulocyte colony stimulating factor (G-CSF) from September 1991. Marked increase of hematopoietic cells in his bone marrow was observed, and maintenance administration of G-CSF was continued. 15 months later, myeloblasts with nuclear abnormality increased, and 22 months later, myeloblasts with chromosomal abnormality presenting 46, XY, -7, +21 exceeded 20%, and aplastic anemia seemed to be transformed into refractory anemia with excess of blasts in transformation (RAEB in T). The usefulness of G-CSF in the treatment of aplastic anemia is now established, but there are some reports questioning the effect of long-term administration, especially transformation to MDS with monosomy 7. Leukemic transformation from aplastic anemia is very complex, but in some cases, long term administration of G-CSF may affect the natural course and may lead to the earlier development of leukemia.

Abstract
Bilateral ankle skin ulcers developed in a 61-year-old man in the chronic phase of chronic myelogenous leukemia receiving hydroxyurea therapy. The circulating immune complex (anti-C3d antibody) was high in this case, but vasculitis was not observed in the pathological findings of biopsied skin materials. This association has been reported in patients who had chronic myelogenous leukemia or other myeloproliferative disorders and were treated with hydroxyurea. It is likely that skin ulcers are caused by hydroxyurea.

The present study was done to identify and characterize the isoenzymes of cyclic nucleotide phosphodiesterase (PDE) and to determine their intracellular distribution in human kidney and heart. The in vitro effects of new cardiotonic agents, namely, NSP-805 (4,5-dihydro-5-methyl-6-[4-[(2-methyl-3-oxo-1-cyclopentenyl)amino] phenyl]-3(2H)-pyridazinone), TZC-5665 (6-[4-[2-[3-(5-chloro-2-cyanophenoxy)-2-hydroxypropylamino]- 2 -methylpropylamino]phenyl]-5-methyl-4,5-dihydro-3(2H)-pyridazinone ) and its metabolites, OPC-18790 ((+/-)-6-[3-(3,4-dimethoxybenzylamino)-2 -hydroxypropoxy]-2-(1H)-quinolinone), MS-857 (4-acetyl-1-methyl-7-(4-pyridyl)-5,6,7,8-tetrahydro-3(2H)-isoquinolinone ) and E-1020 (1,2-dihydro-6-methyl-2-oxo-5-(imidazo[1,2-a]pyridin-6-yl)-3-pyridine carbonitrile hydrochloride monohydrate), on these human PDE isoenzymes were also investigated. PDE isoenzymes were separated from cytosolic and particulate fractions of homogenates of human kidney and heart by DEAE-Sepharose chromatography. PDE isoenzymes were identified by their elution characteristics, substrate specificities, sensitivities to regulation by effectors and by the use of isoenzyme-specific inhibitors. In a cytosolic fraction from kidney, Ca2+/calmodulin-dependent PDE (CaM-PDE), cyclic GMP-stimulated PDE (cGS-PDE), cyclic GMP-inhibited PDE (cGI-PDE) and two forms of cyclic AMP-specific PDE (cAMP-PDE) were resolved. One form of cAMP-PDE (cAMP-PDE alpha), which was eluted at a lower ionic strength than cGI-PDE during DEAE-Sepharose chromatography, was newly recognized in human tissues, though the other form (cAMP-PDE beta), which eluted later than cGI-PDE, had been previously isolated.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Arterial infusion therapy with anticancer drugs is now attracting attention as a valuable modality for locally advanced breast cancer. Since 1977, we have used this therapy in 122 patients with primary breast cancer. The present report mainly discusses the clinical and histological response as well as the prognosis. The anticancer drugs were mainly given by two routes, infusion into the internal mammary artery and the subclavian artery. Continuous infusion of 5-FU and intermittent injections of MMC, ADR, 4'-epi-ADR and THP-ADR were jointly or individually made in each artery. Clinical response, defined as CR + PR, was noted in 48.4% of 5-FU group and 72.7% of ADR-MMC group. Histological response according to Shimosato Criteria, defined as grade IIb or better, appeared in 45.2% of main tumors and 25.4% of metastatic lymph nodes in the 5-FU group, and 70.9% main tumors and 46.3% of metastatic lymph nodes in the ADR-MMC group. The non-infusion group contained 27.7% of stage IIIb, against 72.2% in the infusion group. The 5-year overall survival rates were non-infusion group 62%, 5-FU group 34.1% and ADR-MMC group 66.2%. A significant difference was seen between the 5-FU infusion group and the ADR-MMC group (p = 0.03). Administration of high dose medroxy progesterone acetate for two weeks and 4'-epi-ADR infusion chemotherapy resulted in an excellent histological response. This combination therapy is a promising neoadjuvant chemo-endocrine therapy for advanced breast cancer.

Abstract
A theoretical equation of state (EOS) for chain molecule fluids is presented based on an improved hole and cell model in which the geometries of both the cells and the mers are defined as the dodecahedrons and reasonably related with the Lennard-Jones potential. Furthermore the number of configurations is treated to contribute to the EOS by means of minimizing the Helmholtz free energy to determine the cell size. This study may be regarded as the improved theories about the hole and cell model proposed by Simha et al. and the hole model by Sanchez and Lacombe. The present EOS has three characteristic parameters per pure fluid, which can lead to a corresponding-state principle for pure polymeric fluids. The validity and applicability of the equation were investigated by correlating the experimental PVT data for some common polymers and predicting the thermal expansion coefficient and isothermal compressibility of PVAc.

Abstract
A case of pure red cell aplasia (PRCA) with various complications polyarthritis, angitis, acute renal failure and DIC was successfully treated with steroid pulse therapy was described. A 55-year-old woman was hospitalized with a 9-month of intermittent but progressive joint pain, morning stiffness, general fatigue, and fever. Her initial laboratory evaluation revealed a hemoglobin of 4.4 g/dl and absence of reticulocyte. Her bone marrow aspirate showed no erythroblast which was compatible with a diagnosis of PRCA. Marked leukocytosis and thrombocytosis, positive antinuclear antigen, elevation of gammaglobulin and C-reactive protein and the presence of polyarthritis and angitis which was confirmed by renal angiography, indicated an underlying autoimmune disorders. Steroid pulse therapy was administered at 500 mg/day for 3 days, resulting in the complete response in both red cell aplasia and above findings. PRCA is known to be associated with systemic lupus erythematosus and rheumatoid arthritis very rarely, but this case did not fulfill the criteria of known collagen diseases, and there is no previous report representing PRCA with various complications such as polyarthritis, angitis and acute renal failure. This case may help us to understand more about the relationship between PRCA and autoimmune disorders.

Abstract
We describe an autopsy case of severe intracranial hemorrhage which occurred during the infusion of tissue plasminogen activator (t-PA) for acute myocardial infarction. A 75-year-old man was admitted with substernal chest pain of 3-h duration and electrocardiographic changes consistent with an acute inferior myocardial infarction. Physical examination was unremarkable, except for an initial blood pressure reading of 160/96 mmHg. The patient received 3,000 IU intravenous heparin followed by a 2.4 x 10(6) IU bolus dose of tissue plasminogen activator (t-PA) (Alteplase). This was followed by a drip infusion of 21.6 x 10(6) IU of t-PA over 1 h (total dose 41 mg). Thirty minutes after the infusion of t-PA was initiated, the patient suddenly lost consciousness and began to have violent convulsions, followed by cardiac arrest. Autopsy revealed massive hemorrhage in the bilateral cerebrum and brain stem. To our knowledge, this is the first case of sudden death during t-PA infusion therapy.

Abstract
Two cases of hypereosinophilic syndrome (HES) that seemed to be myeloproliferative disorders were treated with interferon-alpha (IFN-alpha). Case 1 was a 45-year-old man with HES who was unresponsive to prednisolone. Because Flaum's hematologic grading score was 8 points, he was diagnosed as a myeloproliferative variant of HES. Although his condition was well controlled by hydroxyurea (HU), cardio-pulmonary insufficiency with refractory eosinophilia developed after 4 years. Instead of HU, IFN-alpha dramatically decreased eosinophil counts, and the clinical situation has stabilized since. Case 2 was a 30-year-old man with HES whose grading score was 9 points. IFN-alpha therapy was started when an accelerated phase of neutrophil dominant with chromosomal abnormality (8 trisomy) occurred. However, he died because of no response to IFN-alpha and other chemotherapy. In both cases, studies of eosinophil colony formation revealed no excess of eosinophil colony-stimulating factor from their lymphocytes. Flaum's hematologic grading score was useful for the diagnosis of myeloproliferative variants of HES. IFN-alpha successfully induced hematologic remission in one case, and this therapy may be beneficial for these patients as a first line agent.

Abstract
Ciclosporine (CS) caused rapid improvement of anemia and increase of CD 4/8 ratio in two patients with pure red cell aplasia (PRCA). One case was a 45 year old female who were unresponsive to steroids, plasmapheresis and high dose cyclophosphamide, and another was a 61 years old man with diabetes mellitus (DM) without any treatment for PRCA. In both cases hemoglobin increased soon after the initiation of CS and CD 4/8 ratio also rose from 0.80 to 1.47 and 1.78 to 1.98, respectively. There was no side effects to interrupt the course of the therapy. CS seems to inhibit the production of cytokines such as IL-2 and IFN-gamma, and it damages the activated suppressor/cytotoxic T cells. CS is an effective drug for not only refractory cases but the first step therapy for the untreated patients.

Abstract
We examined the inhibitory effects of vesnarinone, a new cardiotonic agent, on human cyclic nucleotide phosphodiesterase (PDE). Vesnarinone selectively inhibited the activity of human cardiac cGMP-inhibited PDE with a Ki value of 8.5 microM. The inhibition of human cardiac cGMP-inhibited PDE by vesnarinone was not competitive but was of the mixed type with respect to cAMP. Although the activities of the cGMP-inhibited PDE from human heart, aorta, platelets, and kidney were inhibited to the same extent by cGMP, enoximone, and cilostazole, vesnarinone inhibited the activities of cardiac and kidney cGMP-inhibited PDE with 10 times greater potency than those of platelet and aorta cGMP-inhibited PDE. These results suggest that there exist, in human tissues, two isoforms of cGMP-inhibited PDE that can be distinguished by reference to the inhibitory effects of vesnarinone.

Abstract
A case with multiple myeloma complicated with hemophagocytic syndrome (HS) is presented. Because pancytopenia, liver dysfunction and increase of mature histiocytes in the bone marrow appeared rapidly a diagnosis of HS was made. The patient died of multiple organ failure, despite steroid therapy. Autopsy revealed marked invasion of hemophagocytic histiocytes not only into the bone marrow but also into many other organs such as the liver, lymph nodes and kidneys. HS is a histiocyte proliferative disorders, which is likely to be seen in immunocompromised hosts, but there is no previous report about HS and multiple myeloma.

Abstract
The authors evaluated the efficacy of a daily administration of recombinant human alpha 2a interferon (IFN), given at a dose of 300MU for 12 consecutive days, in patients with steroid-nonresponsive or -dependent idiopathic thrombocytopenic purpura (ITP). Nine patients received courses of IFN therapy. Mean platelet counts rose from 1.39 to 10.9 x 10(4)/microliters and PAIgG decreased from 151.7 to 59.7 ng/10(7) cells. The maximum rise in platelet counts occurred from 10 to 42 days (mean 19.1) after the initiation of IFN. Complete response (CR) was achieved in 3 of 13 courses (23.1%), and partial response (PR) in 8 (61.5%). One CR case continued for longer than 20 months without further treatment, but intermittent IFN therapy was necessary for the other. The increment of the platelet counts was transient in all of the partial responders. No severe side effect requiring interruption of the course of IFN was experienced. Both serum IgG and PAIgG significantly correlated with the increment of platelet counts, therefore the mechanism of IFN on ITP was presumed to be associated with the inhibition of autoantibody production. Daily administration of IFN appears to be an effective and safe treatment protocol for refractory ITP.

Abstract
We observed the changes of molecular markers for hemostatic activation in a patient with acute pulmonary embolism treated with 2 x 10(7) unit tissue plasminogen activator (t-PA). Blood samples were obtained before, just after, at 30 min, 1, 2, 6, and 24 hours after the infusion. Molecular markers included thrombin-antithrombin III complex (TAT), plasminogen-alpha 2 plasmin inhibitor complex (PIC), and thrombomodulin (TM). Marked elevation of TAT was observed from immediately after the t-PA infusion to 6 hours after, although it had been observed for only 1 hour in our previous report on the cases of acute myocardial infarction. PIC level was significantly increased during t-PA infusion but returned to almost baseline value 6 hours after the end of t-PA infusion. This finding was almost the same as the one previously reported concerning acute myocardial infarction cases. TM level increased throughout the evaluation, and remained so, even on the 7th day after t-PA infusion. Our present data revealed a clear difference between the reactive TAT increases after t-PA therapy in acute myocardial infarction cases and in acute pulmonary embolism cases. Our present data also revealed a prolonged elevation of TM during the acute period of pulmonary embolism. It is therefore necessary to keep an eye on the changes of molecular markers for hemostatic activation after t-PA therapy in acute pulmonary embolism.

Abstract
A 38-year-old woman presented with ear pain and vertigo. No hepatosplenomegaly or lymphadenopathy were found, but her platelet counts markedly rose to 414 x 10(4)/microliters with an increase of megakaryocytes in the bone marrow (859/microliters). Cytogenetic assay revealed positive Ph1 chromosome and rearrangement of the break point cluster region (bcr). Although platelet counts remained under 100 x 10(4)/microliters after the administration of carboquone, a high fever and pancytopenia appeared 31 months later. Bone marrow biopsy showed marked myelofibrosis which was improved by low dose etoposide. This case was thought to be Ph1 positive ET, but it was more compatible with CML megakaryocytic predominance type according to the newly proposed "Hannover criteria for myeloproliferative disorders" and cytogenetic assay.

Abstract
Clinical efficacy of oral high-dose cepharanthin (40-60 mg/day) was evaluated in nine patients with idiopathic thrombocytopenic purpura who were unable to discontinue the administration of adrenocorticosteroids or immunosuppressive drugs. Mean platelet counts significantly (p less than 0.05) rose from 4.5 +/- 0.9 x 10(4)/microliters to 8.9 +/- 4.2 x 10(4)/microliters without any side effects. Two to five months after the initiation of this therapy, 4 patients, including 3 who could discontinue adrenocorticosteroids, kept their platelet counts over 10 x 10(4)/microliters. It was suggested that the oral administration of cepharanthin could be a beneficial and safe strategy for ITP.

Abstract
We report an autopsy case of acute erythremia which terminated in generalized infiltration of immature blasts similar to proerythroblasts. A 61-year-old man was admitted because of general fatigue and fever in June, 1990. Mild anemia and severe thrombocytopenia were noted. The bone marrow was hypocellular with 25.5% blasts similar to proerythroblasts and 36.5% erythroblasts, many of which were polynuclear and megaloblastoid. The blasts were cytochemically negative for POX, but positive for PAS staining. Therefore he was diagnosed as having acute erythremia. Partial remission was achieved by BHAC-EV therapy. But three months later, his marrow was replaced by 52.7% blasts as seen in admission. Those blasts were negative for lymphoid, myelocytic, megakaryocytic markers and antiglycophorin A, but positive for OKT 9. Electron microscopy revealed that some of blasts had characteristics of immature erythroblasts. In spite of low dose Ara-C therapy, he died of sudden gastrointestinal bleeding in December, 1990. The autopsy disclosed widespread infiltration of blasts, involving liver, spleen, lung, kidney and stomach. It was interesting that dysplasia had been confined to erythroid lineage throughout his clinical course. He seemed to be a rare case of blastic form of acute erythremia which should be distinguished from erythroleukemia.
