Abstract
The CXCR3 ligands CXCL9, 10, and 11 play critical roles in the amplification of immune responses by recruiting CXCR3+ immune effector cells to the tumor site. Taking advantage of this property of CXCR3 ligands, we aimed to establish a novel approach to identify immunogenic mutated-antigens. We examined the feasibility of using CXCR3 ligand mRNAs as sensors for detection of specific immune responses in human and murine systems. We further investigated whether this approach is applicable for the identification of immunogenic mutated-antigens by using murine sarcoma lines. Rapid synthesis of CXCR3 ligand mRNAs occurred shortly after specific immune responses in both human and murine immune systems. Particularly, in CMS5 tumor-bearing mice, we detected specific immune responses to mutated mitogen-activated protein kinase 2 (ERK2), which has previously been identified as an immunogenic mutated-antigen. Furthermore, by combining this approach with whole-exome and transcriptome sequencing analyses, we identified an immunogenic neo-epitope derived from mutated staphylococcal nuclease domain-containing protein 1 (Snd1) in CMS7 tumor-bearing mice. Most importantly, we successfully detected the specific immune response to this neo-epitope even without co-administration of anti-cytotoxic T-lymphocyte protein-4 (CTLA-4), anti-programmed cell death-1 (PD-1) and anti-glucocorticoid-induced TNFR-related protein (GITR) antibodies, which vigorously augmented the immune response and consequently enabled us to detect the specific immune response to this neo-epitope by conventional IFNγ intracellular staining method. Our data indicate the potential usefulness of this strategy for the identification of immunogenic mutated-antigens. We propose that this approach would be of great help for the development of personalized cancer vaccine therapies in future.

Abstract
PURPOSE Preparative lymphodepletion, the temporal ablation of the immune system, has been reported to promote persistence of transferred cells along with increased rates of tumor regression in patients treated with adoptive T-cell therapy. However, it remains unclear whether lymphodepletion is indispensable for immunotherapy with T-cell receptor (TCR) gene-engineered T cells. EXPERIMENTAL DESIGN We conducted a first-in-man clinical trial of TCR gene-transduced T-cell transfer in patients with recurrent MAGE-A4-expressing esophageal cancer. The patients were given sequential MAGE-A4 peptide vaccinations. The regimen included neither lymphocyte-depleting conditioning nor administration of IL2. Ten patients, divided into 3 dose cohorts, received T-cell transfer. RESULTS TCR-transduced cells were detected in the peripheral blood for 1 month at levels proportional to the dose administered, and in 5 patients they persisted for more than 5 months. The persisting cells maintained ex vivo antigen-specific tumor reactivity. Despite the long persistence of the transferred T cells, 7 patients exhibited tumor progression within 2 months after the treatment. Three patients who had minimal tumor lesions at baseline survived for more than 27 months. CONCLUSIONS These results suggest that TCR-engineered T cells created by relatively short-duration in vitro culture of polyclonal lymphocytes in peripheral blood retained the capacity to survive in a host. The discordance between T-cell survival and tumor regression suggests that multiple mechanisms underlie the benefits of preparative lymphodepletion in adoptive T-cell therapy.

Abstract
We hypothesised that an in-vivo adjustment method and/or a newer sensor would increase the accuracy of non-invasive and continuous haemoglobin monitoring (SpHb) measurements. Two sensors, the R1-25 and R2-25a (the newer version), were used with laboratory total haemoglobin concentration (tHb) values simultaneously recorded. In-vivo adjusted SpHb (AdHb) was calculated by a simple formula: AdHb = SpHb - (1(st) SpHb - 1(st) tHb). The correlation coefficients between SpHb (or AdHb) and tHb were compared: SpHb in both sensors correlated strongly with tHb (p < 0.0001). In-vivo adjustment improved the correlation coefficient between SpHb and tHb from 0.86 to 0.95 for the R1-25 and from 0.83 to 0.93 for the R2-25a. There was no difference between the R1-25 and R2-25a sensors. The in vivo adjustment method improved the accuracy of SpHb measurements in both sensors.

Abstract
We investigated whether PSK (a polysaccharide from the mycelia of Coriolus versicolor) or OK-432 (a streptococcal preparation) can up-regulate inducible nitric oxide synthase (iNOS) gene expression and nitric oxide (NO) production in mouse peritoneal polymorphonuclear leukocytes (PMNs). Six hrs after intraperitoneal injection of mice with PSK (2,500 microg/mouse) or OK-432 (100 microg/mouse), mouse peritoneal PMNs were restimulated with PSK (500 microg/ml) or OK-432 (10 microg/ml) plus 100 U/ml of mouse interferon-gamma (IFN-gamma) in vitro. Northern blot analysis showed strong synergism between both PSK and OK-432 and IFN-gamma for the induction of iNOS gene expression. NO production by PMNs was increased up to 20 microM (2 microM/10(6) PMNs/24 hrs) as measured by the Griess reagent method when PMNs were restimulated with PSK or OK-432 plus IFN-gamma for 24 hrs, although tumor cell killing was not detected. NO concentrations of more than 80 microM were required for P815 tumor cell killing. These results suggest that PMNs produce NO after stimulation with PSK or OK-432 in combination with IFN-gamma and may regulate the immune system in vivo, although the NO production induced by these agents is insufficient for tumor cell killing in vitro.

Abstract
A 31-year-old pregnant woman with a history of several episodes of deep vein thrombosis was scheduled for Caesarian section. The patient had an increased risk of intraoperative pulmonary thromboembolism due to thrombi isolated from deep veins. This is because a thrombus can be formed easily in deep veins by the influence of hypercoagulability in the third trimester and by the disturbance of venous return due to the pressure of the enlarged pregnant uterus. A temporary IVC filter (Filtre Thery, France) was inserted preoperatively. The filter basket was set in the IVC cephalad from the left renal vein and caudad from the hepatic vein. The operation was completed without any trouble. Rehabilitation was safely initiated just after the surgery by insertion of the filter and then the filter was removed on the third postoperative day. We conclude that the preoperative insertion of a temporary IVC filter is a useful technique to prevent intraoperative pulmonary thromboembolism in a patient with a history of deep vein thrombosis.

Abstract
A 52-year-old male was scheduled for right upper lobectomy due to lung cancer. The patient was diagnosed as having stable idiopathic interstitial pneumonia (IIP) based on preoperative lung biopsy, physical examination and laboratory data. He received prophylactic steroids to prevent an acute exacerbation of IIP. However, he fell into severe hypoxia 5 days after operation, and died of respiratory failure 43 days after operation. It must be born in mind that the patients with IIP may suffer exacerbation even if their lungs have been diagnosed as in stable stage. Prophylactic use of steroids may cause a deterioration in IIP due to delayed healing and infection.

Abstract
We report on the first case of X-linked recessive myotubular myopathy (MTM1) coinciding with Duchenne muscular dystrophy (DMD). The muscle biopsy specimens of the patient show only the characteristic findings of MTM1, without the findings of DMD. We theorize that this was caused by the muscle fiber immaturity and inactivity.

Abstract
We investigated the efficacy of the streptococcal preparation OK-432 as an adjuvant for in vivo priming in induction of sensitized cells for adoptive immunotherapy of the poorly immunogenic B16-BL6 (BL6) melanoma. C57BL/6 (B6) mice were immunized subcutaneously (s.c.) with 3 x 10(6) viable BL6 tumor cells admixed with various doses of OK-432 ranging from 1 to 100 micrograms in the foot-pad. Draining popliteal lymph nodes (LNs) were harvested 7 days after immunization and LN cells were further sensitized with irradiated tumor cells in the presence of 60-300 IU/ml of IL-2 for 11 days. These in vitro sensitized (IVS) cells (2 x 10(6)) were transferred intravenously (i.v.) to B6 mice bearing 4-day pulmonary metastases established by i.v. injection of 2-4 x 10(5) viable BL6 cells. The mice were also received intraperitoneally (i.p.) 4 x 10(4) IU/day of IL-2 for 4 days after adoptive transfer. Transfer of IVS cells from mice immunized by s.c. injection of tumor cells admixed with 10 micrograms of OK-432 significantly reduced the numbers of BL6 pulmonary metastases compared with that of control IVS' cells without the administration of OK-432 (P = 0.003). These effective IVS cells also significantly prolonged the survival of treated animals (P = 0.003). Functional IVS cells required in vitro stimulation with tumor cells. However, addition of OK-432 in the vaccine resulted in no enhancement of in vitro cytotoxicity and no characteristic change of phenotype of IVS cells. These results suggest that in vivo priming of OK-432 facilitates the sensitization of tumor-reactive T-cells. The procedure of in vivo priming with OK-432 may be beneficial in the adoptive immunotherapy of melanoma.

The morphologic changes in PMNs induced by an i.p. injection of PSK, a polysaccharide from the mycelia of Coriolus versicolor, and tumor cells undergoing cell death, were evaluated by immunohistochemical staining and electron microscopy. Male C3H/He mice, 8-10 -weeks old, received an i.p. injection of 125 mg/kg of PSK. Their PMNs were obtained 6 h after the PSK injection by peritoneal lavage. N-CWS (Nocardia rubra cell wall skeleton) was added at the start of the chromium release assay using the MM46 mammary carcinoma cell line, which is syngeneic to C3H/He mice, as target cells. During the cytotoxic assay, the cells were fixed at various time points. The MM46 cells expressed ICAM-1 while the PMNs expressed both ICAM-1 and LFA-1 as determined by immunohistochemical staining and immunoelectron microscopy using anti-ICAM-1 and anti-LFA-1 antibodies. PMNs with ruffle-like microvilli adhered to the MM46 tumor cells 30 min after the addition of N-CWS. Immunoelectron microscopic findings suggested that the adhesion molecules were LFA-1 on the PMNs and ICAM-1 on the MM46 tumor cells, but cell fusion between the PMNs and tumor cells was not observed. The MM46 tumor cells gradually lost their microvilli, which showed cell damage, and died 6-7 h after the addition of the N-CWS. This time course of tumor cell death is compatible with the results of the cytotoxic assay. Pretreatment of PMNs by anti-LFA-1 antibody suppressed 1% lysis of MM46 tumor cells from 90% to 10% (p < 0.01). These data suggest that adhesion molecule on the surface of PMNs such as LFA-1 might play an important role on signal transduction of these PMNs cytotoxic function in this experimental system.

Abstract
We investigated the efficacy of intratumoral administration of biological response modifiers (BRM) in induction of in vitro sensitized (IVS) cells for adoptive immunotherapy of the poorly immunogenic MCA 102 sarcoma and B16-BL6(BL6) melanoma. We used the bacterial immunoadjuvant Nocardia rubra cell wall skeleton (N-CWS), and a streptococcal preparation, OK-432, for MCA 102 and BL6, respectively. After C57BL/6(B6) mice were inoculated subcutaneously (s.c.) with viable MCA 102 or BL6 tumor cells in the foot-pad, mice were injected intratumorally (i.t.) with N-CWS ranging from 10 to 400 micrograms or OK-432 ranging from 1 to 100 micrograms. Draining popliteal lymph nodes (LN) were harvested 7 days after i.t. administration of BRM, and LN cells were cultured with irradiated tumor cells in the presence of IL-2 for 11 days. These IVS cells (7.5 x 10(6) or 2 x 10(6)) were transferred intravenously (i.v.) to B6 mice with 4 day pulmonary metastases established by i.v. injection of viable MCA 102 cells (1 x 10(6)) or viable BL6 cells (3 x 10(5)). The mice were also received intraperitoneally 4 x 10(4) IU/day of IL-2 for 4 days after adoptive transfer. The transfer of IVS cells from mice immunized by i.t. injection of 100 micrograms of N-CWS 1 week after inoculation of tumor cells significantly reduced MCA 102 pulmonary metastases, compared with control IVS cells without administration of N-CWS. Moreover, the transfer of IVS cells from mice immunized by i.t. injection of 10 micrograms of OK-432 3 days after inoculation of tumor cells significantly reduced BL6 pulmonary metastases compared with control IVS cells without administration of OK-432. The administration of N-CWS resulted in no enhancement of in vitro cytotoxicity. Although the administration of 10 micrograms of OK-432 augmented in vitro cytotoxicity of IVS cells against BL6, cytotoxic activity was lower than that of IVS cells immunized with N-CWS. The major phenotype was CD8+ cells in IVS cells immunized with N-CWS or OK-432. These results suggest that i.t. administration of N-CWS and OK-432 facilitates the production of sensitized T-cells, and this administration route of BRM may be useful in the adoptive immunotherapy of human cancer.

Abstract
This study was undertaken to clarify the susceptibility to infection of patients with diabetes mellitus. The complement system is activated through the classical and/or the alternative pathways to produce many kinds of anaphylatoxins in the inflammatory process. One of the anaphylatoxins, C5a, possesses both the strong biological activity of a chemotactic factor and the increasing effect of CR1 and CR3 expression on polymorphonuclear leukocytes (PMNs). It is well known that the complement receptors, CR1 and CR3, on PMNs play important roles in the phagocytosis. We studied the changes of the expression of these receptors on PMNs in non-insulin dependent diabetes mellitus after the stimulation with recombinant human C5a. PMNs from 11 patients with non-insulin dependent diabetes mellitus and 11 normal controls were tested. There was no significant difference of CR1 and CR3 expression on PMNs after the addition of 10 ng/ml C5a between patients with diabetes mellitus and normal controls. However, by the stimulation with 50 ng/ml C5a, the increase of the CR3 expression on PMNs of patients with diabetes mellitus was significantly smaller than normal controls (p < 0.02). The increase of the expression of CR1 on PMNs was not significantly different the two groups. It is suggested that the small increase of the CR3 expression on PMNs by the stimulation with C5a is one of the factors of the susceptibility to infection in patients with diabetes mellitus.

Abstract
The dystrophin gene was examined by PCR analysis in 30 Japanese patients with Becker muscular dystrophy (BMD). Fifteen PCR of these patients had exon deletion, generally, less than three exons. Muscle biopsies were also performed in 20 BMD patients (10 with sequence deletions, and 10 without detectable sequence deletions) in order to correlate PCR findings with immunoblot and immunostaining data. A patchy, heterogeneous membrane immunostaining pattern of reduced intensity was found, irrespective of the presence or absence of deletions. Immunoblotting studies demonstrated dystrophin of low molecular mass and quantity in BMD patients with deletion mutations, while a low quantity of dystrophin with an apparent wild type molecular mass was observed in nearly half the BMD patients without detectable deletions. However, these dystrophins were also found to have slightly abnormal molecular masses when the standard electrophoresis time was prolonged. This suggests that immunoblots and PCR data correlate well in patients with BMD. Additionally, it is suggested that immunoblot assays can detect abnormalities in dystrophin in the absence of detectable PCR deletions.

Abstract
Polymorphonuclear leukocytes (PMNs) recovered from the peritoneal cavity of mice treated with the streptococcal preparation OK-432, exhibited strong cytotoxicity after the in vitro addition of Nocardia rubra cell wall skeleton (N-CWS). In this study, we investigated whether recombinant human granulocyte colony-stimulating factor (rhG-CSF) could augment the cytotoxicity of OK-432-induced PMNs after the addition of N-CWS in vitro. PMNs recovered from the peritoneal cavity of 8- to 10-week-old, male C3H/He mice induced by intraperitoneal (i.p.) injection of 50 KE/kg (1 KE = 0.1 mg) of OK-432 were used in a 51Cr release assay against MM46 mammary carcinoma cells. While addition of rhG-CSF in vitro did not augment the cytotoxicity of OK-432-induced PMNs, marked augmentation of the cytotoxicity of OK-432-induced PMNs was observed following a single subcutaneous (s.c.) or i.p. injection of 125 micrograms/kg of rhG-CSF. The effect of in vivo administered rhG-CSF was dependent on the timing of the injection with respect to OK-432 administration and differed from s.c. or i.p. injections. Interestingly, the cytotoxicity of OK-432-induced PMNs was rather weak following consecutive s.c. or i.p. administration of rhG-CSF for 7-14 days. H2O2 is likely involved in mediating the cytotoxicity of OK-432-induced PMNs since activity was significantly reduced by the in vitro addition of low concentration of catalase. Generation of H2O2 by the PMNs correlated with cytotoxicity. These results suggest that in vivo administration of rhG-CSF augments the cytotoxicity of OK-432-induced PMNs in a time dependent fashion and that H2O2 plays an important role in mediating their cytotoxicity.

Abstract
Currently available techniques used to recognize point mutations in genetic disease are time consuming and are capable of screening only small pieces of DNA. Moreover, they detect all sequence differences including phenotypically silent changes. Consequently, they are not convenient to analyse mutations in large, multi-exonic genes, where a large fraction of pathological point mutations arises from early termination, as is the case for the one third non-deletion/duplication cases of Duchenne Muscular Dystrophy. We have developed a rapid and sensitive method, the Protein Truncation Test (PTT). PTT is based on a combination of RT-PCR, transcription and translation and selectively detects translation-terminating mutations. We demonstrate its effectiveness to detect point mutations in DMD-patients and carrier females. PTT should be widely applicable diagnostically in any disease where early terminations contribute substantially to the disease cause.

Abstract
A 70-year-old man with Hashimoto's disease had selective IgM deficiency, while other immunoglobulin levels were normal. In vitro mixing experiments were carried out in which B cells and T cells from the patient and from a healthy control donor were co-cultured in the presence of pokeweed mitogen, in order to investigate the etiology of IgM hypoproduction. The results indicated that the patient had B-cell dysfunction, involving the impairment of B-cell differentiation. In addition, both IgG of the healthy control donor and thyroid hormone may play important roles in the pathogenesis of this case.

Abstract
We investigated whether recombinant human granulocyte colony-stimulating factor (rhG-CSF) enhanced the cytotoxicity of PSK-induced polymorphonuclear leukocytes (PMNs) in the peritoneal cavity. Male C3H/He mice, 8- to 10-week-old, received single subcutaneous (s.c.) or intraperitoneal (i.p.) injection of 2.5 micrograms/animal of rhG-CSF at different time points before or after an i.p. administration of PSK. In other experiments, mice were s.c. or i.p. treated with the same dosage of rhG-CSF every day for 7 or 14 consecutive days and i.p. injected with 2.5 mg/animal of PSK on the last day. Peritoneal PMNs were harvested 6 hrs after the administration of PSK and purified to more than 95% by Ficoll-Paque for in vitro cytotoxic assay. In vitro cytotoxic assays with 51Cr labeled MM46 mammary carcinoma cells were added with 5-20 micrograms/ml of Nocardia rubra cell wall skeleton (N-CWS) at the beginning of the assay to augment the cytotoxic activity of PMNs. In vitro addition of rhG-CSF to the assay did not enhance the cytotoxicity of PSK-induced PMNs. However, the cytotoxicity was significantly increased when rhG-CSF was s.c. administered 12 hrs before a PSK injection or 2 or 5 hrs after that. On the other hand, the cytotoxicity was rather weak when mice s.c. or i.p. received consecutive injections of rhG-CSF. This cytotoxicity may be mediated by H2O2, since H2O2 production of PMNs during the cytotoxic assay appears to correlate with the levels of cytotoxicity under suppressed H2O2 generation by catalase or enhanced generation by rhG-CSF. These results suggest that rhG-CSF augments the cytotoxicity of PSK-induced PMNs when administered in vivo timely.

Abstract
A case of secondary myelodysplastic syndrome (MDS) following chemotherapy for lung cancer is reported. A 78-year-old man, with a smoking history of 20 cigarettes/day for 55 years, was incidentally, diagnosed as having stage IV squamous cell carcinoma of the lung in 1987 during admission for transurethral resection of bladder cancer. He received combination chemotherapy of mitomycin C, vincristin, and cisplatin for his lung cancer between July and September 1988. His clinical course remained almost stable until October 1989, when his blood count showed severe anemia and thrombocytopenia. He was diagnosed as having secondary MDS induced by cytotoxic agents used for the treatment of lung cancer, based on the dysplastic findings of precursor cells in the bone marrow and the chromosome abnormality of 51XY, +8, +9, +21, 3p-, 5q-, +2mar. He died of infection with the progression of MDS in March 1990.

Abstract
Peritoneal polymorphonuclear leukocytes (PMNs) were collected from the peritoneal cavity of C3H/He mice 6 hrs after intraperitoneal (i.p.) injection of 2.5 mg/head of PSK, 1 KE (100 micrograms)/head of OK-432 or 200 micrograms/head of Nocardia rubra cell wall skeleton (N-CWS). Without in vitro stimulation, these PMNs did not show cytotoxicity to syngeneic MM46 mammary carcinoma cells in 51Cr release assay. Cytotoxicity of these PMNs was augmented by the addition of 25 micrograms/ml of N-CWS but not of PSK or OK-432 to cultures for the assay at the beginning of the culture. H2O2 production of PSK-induced PMNs was increased by the in vitro addition of 25 micrograms/ml of N-CWS but not of PSK. These results suggest that PSK as well as OK-432 and N-CWS can induce PMNs capable of responding further to N-CWS as the second stimulant.

Abstract
The role of superoxide and lipid peroxidation for anti-tumor effect of intra-arterial injection with degradable starch microspheres (DSM) was investigated in rabbits. The anti-tumor effect of intra-arterial injection with DSM was studied in rabbits with VX2 carcinoma of the hind leg. The tumor growth in rabbit treated with DSM 5 times was completely suppressed, and thiobarbituric acid (TBA)-reactive substances in the tumor tissue treated with DSM were significantly increased. But the anti-tumor effect of DSM and the increase in TBA reactive substances in the tumor tissue treated with DSM were significantly inhibited by treatment with superoxide dismutase combined with catalase. These results suggest that the anti-tumor effect of intra-arterial injection with DSM may be due to ischemia-reperfusion injury and that active oxygen species and lipid peroxidation may play an important role in the anti-tumor effect of intra-arterial injection with DSM.

Abstract
The expression of complement receptor type 1 (CR1) and type 3 (CR3) on polymorphonuclear leukocytes (PMNs) and generation of complement fragments, C3a, C5a, C4d, iC3b and Bb, were studied in patients during hemodialysis using cuprammonium rayon (Cu) membranes. Furthermore, the relation between the expression of CR1 and CR3 on PMNs from healthy donors and complement fragments was investigated. The expression of CR1 and CR3 on PMNs increased during hemodialysis. Plasma C3a, C5a and iC3b levels increased in the first 15 minutes and then decreased at 120 minutes of dialysis. But plasma Bb level remained high until the end of hemodialysis. Purified Bb had no effect on the expression of CR1 and CR3 on PMNs, but C5a augmented those expression in vitro. Nafamostat mesilate, an artificial proteinase inhibitor, inhibited augmentation of complement receptors on PMNs in concentration dependent fashion. C5a generated through the activation of complement was thought to take an important role in the increased expression of CR1 and CR3 on PMNs.

Abstract
Transcatheter chemoembolization using degradable starch microspheres (DSM) was performed in 17 patients with liver metastases of colorectal cancer. DSM, 45 microns in diameter, which are easily degraded by serum amylase, and therefore obstruct arterial blood flow temporarily at the arteriolar capillary bed. DSM mixed with mitomycin C were administered through the catheter introduced by Seldinger's method in 13 cases, and through subcutaneously implanted drug delivery system (Port-A-Cath) in 4 cases. The treatment was repeated 5 times on the average at intervals of 2 to 4 weeks. The therapeutic effect of this chemoembolization was evaluated by the change in tumor size measured by angiography or computed tomography. Tumor regression of over 50% was observed in 9 of 17 cases (53%). Elevated serum CEA levels (greater than 10 ng/ml) decreased in 10 of 15 cases (67%). One-year survival rate was 48% in 17 cases, and among them it was 100% in 7 cases with the extent of several liver metastases (H2). Extrahepatic metastasis was observed in 3 of 17 cases (18%) before the treatment, and in 8 cases (47%) after the treatment. Abdominal pain occurred in 36% of the cases by the administration of DSM, but the pain disappeared within 2 hours. No major side effects such as bone marrow suppression or hepatotoxicity were observed. Our results suggest that chemoembolization using DSM is effective and safe in the treatment of liver metastases from colorectal cancer.

Abstract
Using a murine acute serum sickness model caused by cationized bovine gamma-globulin (CBGG), the histological findings, accumulation of CBGG in the organs and the effect of decomplementation for the clearance of immune complex (IC) were investigated. The accumulation of CBGG increased in the lungs in the presence of anti-CBGG antibody 1 hour after injection of CBGG, but did not change in the kidneys. This suggests that CBGG forms IC in situ in the kidneys, and that circulating IC accumulates in the lungs. Decomplementation did not influence the uptake of CBGG immediately after challenge but delayed the clearance of CBGG in the kidneys, lungs, liver and spleen. A beneficial role of the complement system in the clearance of IC even for those formed in situ was recognized. Histological changes, cellular infiltration and microvascular destruction, evoked in the lungs in this experimental model immediately after challenge, were not seen in the kidney, suggesting the different modes of complement activation in these organs.

Abstract
Blood vessels in muscle biopsy specimens from 6 Fukuyama type congenital muscular dystrophy (FCMD) patients were examined by electron microscopy and compared with ones in non-diagnostic biopsy specimens from age-matched controls and patients with childhood neuromuscular disorders. The most striking feature was the blister-like swelling of vascular endothelial cells in the biopsied muscle specimens from 5 of the 6 patients with FCMD. Morphometric analysis of capillaries in biopsied muscles showed the extremely greater capillary, endothelial and pericyte areas in the FCMD patients than in controls. These phenomena are quite similar to those found in Duchenne muscular dystrophy (DMD) at the preclinical stage and suggest an as yet undetermined process in blood vessels in FCMD as well as DMD. An immunohistochemical study involving dystrophin antibodies showed positive staining in FCMD.

Abstract
An autopsy case of infantile osteopetrosis complicating neuronal ceroid-lipofuscinosis is reported. Autopsy revealed generalized sclerosis and thickening of cortical and spongy bones, formation of mineralized cartilagenous tissues, and narrowing of the marrow cavities associated with decreased hematopoietic cell components. Around the thickened bone trabecles, osteoclasts lacked a ruffled border and clear zone along the cell membrane facing the bone matrix surface. The brain was markedly atrophic with neuronal cell loss and focal gliosis, and the remaining neuronal cells accumulated brown granular pigments, which were confirmed histochemically and electron-microscopically to be ceroid and lipofuscin. In the cerebral medulla, the development of myelin sheaths was extremely poor. Also, the occurrence of Lex type glycolipids and GM3 and the apparent absence of cerebroside and cerebroside sulfate were proved by biochemical analysis, suggesting that the brain was still in a stage of embryonic development or still in the process of differentiation. Except for one suggestive case, this is the first case of complicating neuronal ceroid-lipofuscinosis in infantile osteopetrosis.

Abstract
From the result that the activated form of C1-s(C1-s) prolonged the kinetics of hemolysis via complement, this assay was applied to assess C1 esterase inhibitor (C1INH) function. In the kinetic assay, the complement hemolytic activity was evaluated by the time which required to cause 50% reduction of the initial turbidity of sensitized sheep erythrocytes, and was expressed as T1/2. (1) T1/2 of pooled normal human sera (p-NHS) showed dose-dependent prolongation by the addition of various amounts of C1-s. (2) Preincubation of various amounts of functionally pure C1INH with the constant amounts of C1-s inhibited dose-dependently the prolongation of T1/2 by C1-s. (3) The C1INH activity of NHS was 840 +/- 80 units/ml (n = 6) and that of the C1INH deficient serum was 80 units/ml, which were calculated from the standard curve established by the addition of various amounts of purified C1INH. This test requiring only C1-s and sensitized sheep erythrocytes is simple technically and high in sensitivity, and seems to be useful for the routine assay for C1INH function of human sera.

Abstract
The role of superoxide and lipid peroxidation in liver injury induced by ischemia-reperfusion was investigated in rats. Ischemic condition of the liver was created by applying small clamps to the right branch of portal vein and the right hepatic artery for 15 min. Clamping of hepatic artery and portal vein could decrease the hepatic blood flow to about 30% of that measured before the clamping. Levels of serum GPT and thiobarbituric acid (TBA) reactive substances in the liver tissue were significantly increased 30 min after the reperfusion following 15 min of ischemia. The increase in serum GPT and TBA reactants in the liver tissue was significantly inhibited by the treatment with superoxide dismutase combined with catalase. The treatment with allopurinol significantly inhibited the elevation of serum GPT levels and showed a tendency to inhibit the increase in TBA reactants in liver tissue. These results suggest that active oxygen species and lipid peroxidation may play an important role in the pathogenesis of ischemia-reperfusion injury in the liver, and hypoxanthine-xanthine oxidase system may be one of the main sources of active oxygen species.

Abstract
The role of oxygen-derived free radicals and lipid peroxidation in the pathogenesis of acute gastric mucosal erosion was investigated in rat models produced by burn shock stress, by treatment with regional hyperthermia, platelet activating factor, and compound 48/80, and by ischemia-reperfusion. In all experimental models, the increase in the gastric erosions and in TBA reactants in the gastric mucosa were significantly inhibited by the treatment with superoxide dismutase (SOD) and/or catalase. Pretreatment with allopurinol, a competitive inhibitor of xanthine oxidase, prevented considerably the gastric injury (a) induced by burn shock, (b) produced by treatment with compound 48/80, and (c) caused by ischemia-reperfusion. By the treatment with anti-rat neutrophil antibody, the gastric mucosal injuries induced by regional hyperthermia, platelet activating factor, and compound 48/80 were significantly inhibited; however, burn shock and ischemia-reperfusion injuries were not inhibited. These results suggest that oxygen-free radical and lipid peroxidation contribute to the formation of gastric mucosal lesions, and that the sources of oxygen radicals seem to be different among these experimental models.

Abstract
The kinetics of hemodialysis-induced leukopenia and generation of complement fragments including C3a, C5a, C4d, iC3b and Bb were investigated in 14 patients during hemodialysis using cellulose acetate (CA), cuprophan (Cu) and ethylenevinyl alcohol (EVA) membranes. A marked leukopenia in the first 15 minutes was observed in CA and Cu. Plasma C3a levels were higher in CA than in Cu and EVA. Plasma C5a levels were higher in CA and Cu than in EVA. There was a negative correlation between the white blood cell counts and plasma C5a levels at 15 minutes (gamma = -0.85, p less than 0.001). Plasma C4d levels showed no increase in all membranes. Plasma iC3b levels were higher significantly in Cu than in CA and EVA. Plasma Bb levels in the first 15 minutes increased significantly in all membranes, and furthermore continued to increase till the end of hemodialysis in CA and Cu. This study revealed that all the membranes tested activated the complement via the alternative pathway to produce Bb, iC3b, C3a and C5a. C5a was thought to take an important role in transient leukopenia. Furthermore, Bb was accumulated during hemodialysis in CA and Cu, and its biological effects on patients undergoing hemodialysis should be studied.

Abstract
Ischemia and reperfusion is of the greatest importance in the pathology of various diseases. This study was designed to investigate the role of oxygen-derived free radicals and lipid peroxidation in gastric mucosal injury induced by ischemia-reperfusion in rats. Clamping of the celiac artery in rats reduced the gastric mucosal blood flow to 10% of that measured before the clamping. Gastric mucosal injury, such as spotty and linear hemorrhagic erosions, was seen in rats 60 min of the reperfusion following 30 min of ischemia. Thiobarbituric acid (TBA) reactants in the gastric mucosa were increased after the reperfusion. The increase in gastric mucosal lesions and TBA reactants were significantly inhibited by the treatment with SOD+ catalase and allopurinol. These results suggest that oxygen-derived free radicals and lipid peroxidation may play an important role in the pathogenesis of acute gastric mucosal lesions induced by ischemia-reperfusion.

Abstract
Two siblings with interstitial deletion of chromosome 14 not associated with ring formation were reported. Clinical features of the patients included failure to thrive, severe mental retardation, microcephaly, round face, hypertelorism, micrognathia and high-arched palate. They were common also in five previously reported cases. Other peculiar finding was hyperthyrotropinemia in their neonatal periods; mild hypothyroidism was found in the elder sister, and hyperthyrotropinemia was only transient in the younger sister. By a high-resolution G-banding analysis, the maternal origin of the chromosome with the deletion was noted.

Abstract
This study consisted of 1) molecular deletion analyses in patients with Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) using the entire cDNA for the DMD gene as hybridization probes, 2) RFLP analyses in a large number of Japanese normal women using 11 DMD-linked cloned DNAs as probes, and 3) segregation analyses with these RFLP data in 17 DMD families in which prenatal or carrier diagnosis was required. The deletion study showed that 18 (43%) of 42 male DMD patients had a deletion within the DMD gene, while no detectable deletion was found in 3 BMD patients. These deletions were preferentially observed at the 5' end of the DMD gene, while no deletion was found in the 3' portion of the gene. Of a total of 15 RFLPs detected with the 11 probes, one was a new RFLP (probe/enzyme: P20/MspI). In 6 RFLPs, the allele frequencies in the Japanese were statistically different from those in the Caucasian. Based on the RFLP data combined with the result of the deletion study, an estimated diagnostic rate for prenatal diagnosis and/or carrier detection in the Japanese DMD families was 63%. The real diagnostic rate obtained from the prenatal and carrier diagnoses, which were practically performed in 17 families, corresponded to the estimation. A protocol useful for the diagnosis in Japanese DMD families is presented.

Abstract
Complement system takes an important role in the pathogenesis of immune complex glomerulonephritis. In this study the precise changes of serum complement and its deposition in the glomeruli were investigated in the mice models induced with cationized bovine gamma-globulin (CBGG). Balb/c mice preimmunized with CBGG were injected intravenously with CBGG three times every 24 hours. Proteinuria and hypoalbuminemia have developed from day 3 until the death on day 9-13 of progressed azotemia. This nephritis resembled to mesangial proliferative glomerulonephritis histopathologically. Immunofluorescent study revealed granular deposits of CBGG, IgG, A, M and C3 along the glomerular capillary loop. Serum C3 decreased to about 50% of normal controls within 1 hour after challenge of antigen and plasma C3 conversion evaluated by crossed-immunoelectrophoresis, occurred in accordance with C3 reduction and then decreased. Immunofluorescent study showed a big difference in the mode of deposition among IgG, CBGG and C3. The most intense deposits of C3 in the glomeruli were seen 12 hours after challenge of CBGG, and then gradually decreased until the next challenge. IgG and CBGG antigen deposited most intensely soon after the challenge of antigen, and gradually decreased. These results led us to conclude that there existed two phases of complement activation in this immune complex induced mice glomerulonephritis; an early phase activation of complement by antigen-antibody complexes in the circulation and later phase activation of complement by immune complexes after deposition of them in situ glomeruli.

Abstract
Transcatheter chemoembolization using Degradable Starch Microspheres (DSM) was performed in 17 patients with liver metastases of colorectal cancer. Mitomycin C mixed with DSM was injected into the proper hepatic artery. Tumor regression of over 50% was observed in 9 of 17 cases (53%). Elevated serum CEA levels (greater than 10 ng/ml) decreased in 10 of 15 cases (67%). One-year survival rate was 50% in 17 cases. One-year survival rate was 100% in 7 cases with several liver metastases (H2). Abdominal pain occurred in 36%, mostly disappearing within 2 hours. No major side effects such as bone marrow suppression or hepatotoxicity were observed. Our results suggest that chemoembolization using DSM is effective and safe in the treatment of liver metastases from colorectal cancer.

Abstract
After K-18 was contacted with various kinds of tumor cell lines in vitro, the binding pattern was examined. K-18 bound on the surface of K-562 cells showed the maximum levels 1 hr later and maintained the binding activity for 24 hrs in the analysis by flowcytometry. K-18 also bound to HeLa S3, KB, RPMI8226, P815, YAC-1 and L1210 cells. Fluorescent intensity on K-562 cells was stronger with whole molecules of K-18 than with F(ab')2 conjugated with melphalan. Normal human IgG could bind more on the surface of K-562 cells than F(ab')2 of IgG. These results suggest that K-18 might bind on tumor cells via IgG Fc receptors on their surface.

Abstract
Antitumor effects and prognosis of the patients with unresectable hepatocellular carcinoma were investigated in the treatment of chemo-embolization using degradable starch microspheres (DSM) and regional hyperthermia. Twenty-six cases were treated with chemo-embolization using DSM alone (Group A) and eighteen cases were treated with combination of chemo-embolization and hyperthermia (Group B). Tumor regression rates over 50% were 42% (11/26) and 56% (10/18) in Group A and Group B, respectively. In the patients with tumors over 7 cm in diameter, no favorable response was obtained in Group A (0/11), but the response rate was increased to 56% (5/9) by the combination of hyperthermia. In the patients with arterio-portal shunt, therapeutic effects were observed in 17% (1/6) and 50% (1/2) of Group A and Group B, respectively. In the patients with portal invasion (Vp2 and Vp3), no favorable response was demonstrated in Group A (0/4), but tumor response was demonstrated in one out of 3 cases in Group B. One- and two-year survival rates were 59% and 53%, respectively, in Group A, and 93% and 45%, respectively, in Group B. The DSM, temporary embolus, is suitable for the combination of hyperthermia because chemo-embolization using DSM can be performed many times. Therefore, these results suggested that chemo-embolization using DSM should be beneficial as combination therapy for unresectable hepatocellular carcinoma.

Abstract
The influences of anti-allergic drugs on superoxide generation from the hypoxanthine-xanthine oxidase system or polymorphonuclear leukocytes (PMN) were studied by an electron spin resonance assay using 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) as a spin trapper. The intensity of DMPO-OOH signal generated from the hypoxanthine-xanthine oxidase system was not influenced by the presence of azelastine, ketotifen, disodium cromoglycate, mequitazine, or methylprednisolone, but it decreased in the presence of AA-673. A kinetic study showed that the second order rate constant for reaction between AA-673 and superoxide anion at pH 7.4 was 2.9 x 10(8)M-1S-1. The relative intensity of DMPO-OOH spin adduct generated from PMN stimulated with phorbol myristate acetate (PMA) or opsonized zymosan (OZ) significantly decreased in the presence of azelastine: from the PMN-PMA system, with 10.7 microM concentration of molar concentration causing 50% reduction of the signal intensity (IC50), while from the PMN-OZ system, with 10.5 microM concentration of IC50, and also decreased in the presence of mequitazine: from the PMN-PMA system, with 10.8 microM concentration of IC50, while from the PMN-OZ system, less than 2.0 microM concentration of IC50. These results suggest that some anti-allergic drugs may have anti-inflammatory and anti-oxidative actions due to scavenging superoxide radicals or due to inhibiting superoxide production.

Abstract
Duchenne muscular dystrophy (DMD) is an X-linked recessive disorder. Recently it has been suggested that the protein named "dystrophin" is not produced in the DMD muscle because of their mutant of defective DMD gene. Recent molecular studies using subclones from the DMD-cDNA as probes revealed a DNA deletion in about a half of the DMD patients. Since not all patients showed deletion, segregation analysis with restriction fragment length polymorphisms (RFLPs) is still necessary and important for diagnosis not only patients but female carriers as well. Therefore, we tried to detect RFLPs with the use of many probes localized within and/or flanked with the DMD gene and made a protocol for the diagnosis with our RFLP data. Among 50 normal Japanese females, the frequencies of rare alleles which identified with enzyme/probe combinations in each were as follows (RFLPs practically available for diagnosis are underlined): 0.38 for p782/EcoRI; 0.14 for p99-6/Pst I: 0.45 for pJ66-HI/Pst I: 0.16 for pERT87-30/Bgl II; 0.44 for 87-15/Xmn I: 0.07 for 87-15/Taq I; 0.33 for 87-8/Taq I; 0.44 for 87-1/Xmn I; 0.45 for 87-1/Mva I; 0.43 for Xj-1.1/Taq I; 0.34 for 754-11/EcoR I; 0.41 for 11.28/Taq I. Some of our results were different from the Caucasian both on the allele frequencies and the restriction fragment length. We proposed a diagnostic protocol of DMD and it's carriers in Japan. Firstly, segregation analysis should be performed with five different combinations of double probe/enzyme, such as Yj-1,.1/L1.28/Taq I, ERT87-1/87-15/Xmn I, 87-1/Mva I, J66-HI/99-6/Pst I, and 782/754-11/EcoR I.(ABSTRACT TRUNCATED AT 250 WORDS)
