Abstract
Feline infectious peritonitis virus (FIPV) infection of feline macro-phages is enhanced by mouse anti-FIPV monoclonal antibody (MAb). This anti-body-dependent enhancement (ADE) of FIPV infection is dependent on mouse MAb subclass, and MAb of IgG2a subclass has a strong ADE activity. Furthermore, MAb showing strong neutralizing activity in Felis catus whole fetus (fcwf-4) cells and Crandell feline kidney (CrFK) cells shows strong enhancing activity in feline macrophages, indicating that the neutralizing epitope and the enhancing epitope are closely related. In this study, we prepared MAb FK50-4 that showed a strong neutralizing activity in feline macrophages, despite the fact that the MAb belonged to the IgG2a subclass. However, MAb FK50-4 did not exhibit neutralizing activity in CrFK cells or fcwf-4 cells, thus showing a very unusual property. MAb FK50-4 recognized FIPV small integral membrane glycoprotein (M protein). Even when feline macrophages were pretreated with MAb FK50-4 prior to FIPV inoculation, this antibody prevented FIPV infection. This reaction disappeared after treatment of FK50-4 with protein A. The neutralizing activity of FK50-4 was also effective on feline macrophages after the cells were inoculated with FIPV. These findings indicated that the FIPV replication mechanism differs between feline macrophages and CrFK/fcwf-4 cells and that a neutralizing epitope that can prevent FIPV infection of feline macrophages after viral absorption is present on M protein.

Abstract
Lipid hydroperoxides (LOOH or oxidized oils) are known as unfavorable food components. Molecular details of the fate and mechanisms of LOOH to exert adverse effects in vivo are, however, little understood. In the present study, we demonstrated that LOOH generated alkylperoxyl radical (LOO*) after reaction with various heme compounds such as myoglobin, cytochrome c, hemin, hematin, etc., but little formation of other radical species was noticed such as L* or LO*. It was also shown that LOO* thus formed exhibits cytotoxicity and caused DNA damages including strand breakage and abasic site formation. This highly toxic LOO* is effectively scavenged by hot water extracts of vegetable (soup), flavonoids, polyphenols as well as tocopherols. Another important finding is that crude vegetable oils are rich in potent-LOO* scavenging activity, which exhibits potent anti-oxidant activity as well; whereas highly purified oils are scanty in such components and LOO* scavenging activity. These findings imply that a considerate processing in the refining of oils should be needed to retain such potent endogenous anti-oxidative radical scavenging-components.

Abstract
Sweet's syndrome occurring during the course of interstitial pneumonitis in a 70-year-old woman was encountered. She was admitted because of dyspnea on exercise, dry cough and interstitial shadow on chest x-ray. Lung biopsy, together with other findings confirmed interstitial pneumonitis. Five days after admission, genital ulcer and aphtha on the oral mucosa were detected and exudative erythema appeared on her right shoulder, chest and back. Histological examination of the skin lesions demonstrated numerous nutrophilic infiltration in the upper dermis, indicating Sweet's syndrome. The skin eruption rapidly disappeared on treatment with colchicine. Although six months after admission interstitial pneumonitis caused respiratory failure, treatment with prednisolone and cyclophosphamide was effective. Serological and immunological tests demonstrated hyper-gammaglobulinemia and positive reaction for anti SS-A antibody. Pathological examination of the lip revealed numerous lymphocyte infiltrates around the duct of the minor salivary gland, suggesting Sjögren's syndrome as the background disease of Sweet's syndrome and interstitial pneumonitis. This evidence indicating that even in elderly patients, skin lesions of Sweet's syndrome may reveal the background disease.

Abstract
Coagulation factor XIII consists of two A- and two B-subunits, and either gene mutation can cause a complete deficiency. In a newborn patient with persistent bleeding from the umbilical cord stump, the plasma A-subunit protein was not detectable. Direct PCR sequencing revealed an nt 389 (ins G) frameshift mutation in exon 4 resulting in a new stop codon and a Ser 413 Leu missense mutation in exon 10 in either allele. His mother and father were heterozygous for the nt 389 (ins G) and the Ser 413 Leu, respectively, with about 50% reduction of the plasma A-subunit proteins. In all family members examined only those with either mutation showed the reduced subunit A protein levels. Thus, this complete deficiency of factor XIII was due to a novel compound heterozygous mutation in the A-subunit gene.

Abstract
Laboratory-made sludge for a biogas based anaerobic biodegradability test was prepared as an alternative for digested sludge from wastewater treatment plants (WWTPs). Biodegradation activities and background gas productions of digested sludge from various WWTPs were found to vary significantly depending on the source, which adversely affected test reliability. Subsequently, test conditions such as sludge concentration and sludge washing were examined with the laboratory-made sludge and a sludge concentration of 1.0 g-SS/L without washing was determined to be most suitable. Under these conditions, biodegradability tests were conducted for 13 select chemicals and their relative toxicities to methanogenic bacteria were evaluated. The results of biodegradability tests showed that chemicals with -OH and -CH2OH radicals were readily biodegraded and those with -Cl, -NO2, -NH2, -SO3H and -CH3 had inhibited degradation responses m-nitriphenol and 2,4,6-trichlorophenol were highly toxic to methanogenic bacteria, with m-nitrophenol completely inhibiting methane fermentation as low as 20 mg/L.

Abstract
Chronic obstructive pulmonary disease (COPD) is more important as a cause of morbidity than as a cause of mortality but estimates of its frequency and distribution are inadequate and incomplete. According to annual report of World Health Organization, in 1998 there were estimated to be 52.2 millions deaths in the world, among them 2.9 millions were due to respiratory diseases and almost of them were COPD. Estimates of prevalence COPD vary depending on the diagnostic criteria used, the age and sex composition of the population, their exposure to cigarette smoke and possibly to other harmful environmental influences. In the present review, we discuss the problems arising in the data of morbidity and mortality of COPD in Japan.

Abstract
An acute exacerbation of chronic obstructive pulmonary disease (COPD) is characterized by an acute worsening of symptoms accompanied by an impairment of lung infection. In severe cases, an acute exacerbation may cause respiratory failure and death. Successful management of acute exacerbation of COPD in either the inpatient or outpatient setting requires attention to a number of key issues. In this review, we discuss the issues regarding the management of COPD which is based on especially characteristics of pathophysiology.

Abstract
The type II feline infectious peritonitis virus (FIPV) epitopes for neutralizing and enhancing antibodies are present on large spike glycoprotein (S) protein. In this study, we established monoclonal antibody-resistant mutant viruses resistant to three different monoclonal antibodies with neutralizing activity in Felis catus whole fetus cells and enhancing activity in feline macrophages, recognizing distinct epitopes on type II FIPV S protein. By comparing the nucleotide sequences of these mutant viruses with that of wild-type virus, we attempted to identify the neutralizing epitopes. The mutations were localized in the region of amino acid residues from 480 to 649 from the N terminal of the S protein.

Abstract
We tested the hypothesis that serum IgE concentrations may be influenced by the severity of respiratory symptoms, impairment of pulmonary functions, and smoking history in elderly patients with bronchial asthma and/or chronic obstructive pulmonary disease (COPD). A total of 325 elderly outpatients aged over 65 years were enrolled in the study: 112 (22 men, 90 women) with bronchial asthma (BA), 135 (118 men, 17 women) with COPD, and 78 (56 men, 22 women) with both COPD and asthma (COPD/BA). The mean ages for the 3 groups were 74.3,76.0 and 76.6 years, respectively; the age differential was not significant. As a group, the male subjects displayed higher serum IgE concentrations than the female subjects. Also, ex-smokers and current smokers showed higher serum IgE concentrations than patients who had never smoked, and patients in the BA group had higher serum IgE concentrations than those in the COPD or COPD/BA groups. Although serum IgE concentrations were increased in BA patients with decreased FEV1.0 levels, the reverse was observed in the COPD patients. Peripheral blood eosinophil counts for men and women were higher in the BA group than in the COPD group. A positive correlation between serum IgE concentration and eosinophil count was observed in the BA group. Although bronchial asthma and COPD in the elderly have been considered to be pathologically similar, the findings of our study suggested they are probably different in terms of serum IgE concentration, pulmonary function, and smoking history.

Abstract
A 61-year-old female who had shown Raynaud's phenomenon and articular swelling for 10 years, was admitted to hospital because of fever of unknown origin (FUO) and dry cough. She was diagnosed by skin biopsy to have a collagen disease or overlap syndrome. Anemia developed rapidly and FUO persisted, but blood culture was negative. Although indomethacin and prednisolone were administered for the progression of clinical signs and symptoms, severe dyspnea developed, resulting in bradycardia, followed by recurrent episodes of ventricular tachycardia. In spite of extensive treatment for her arrhythmia she died on the 9th hospital day. An autopsy revealed generalized Wegener's granulomatosis with extensive cardiac involvement. Necrotizing angitis and severe granulomatous inflammatory foci affected characteristically the common bundle of His and right bundle branch in addition to the ordinary myocardium.

Abstract
A 66-year-old man was admitted with dyspnea on exertion and an abnormal shadow on chest roentgenogram. Transbronchial biopsy yielded a diagnosis of large cell carcinoma of the lung. His dyspnea improved following irradiation and corticosteroid treatment and one month later, he was admitted again for chemotherapy. Because occult blood in stool was detected, upper gastrointestinal endoscopy was performed. Gastric submucosal large cell carcinoma was diagnosed, and this was considered to be metastatic from the lung. Such cases diagnosed prior to death are rare.

Abstract
The killing activity of cord blood mononuclear cells (cMNC) against cytomegalovirus (CMV)-uninfected and -infected fibroblasts was comparable to that of adult peripheral blood mononuclear cells (aPBMC). The killing activity of cMNC against K562 cells was significantly lower compared with that of aPBMC. Treatment of cMNC and aPBMC with interleukin-2 (IL-2), IL-12 or IL-15 significantly enhanced killing activity against K562 cells and CMV-uninfected and -infected cells. By comparison of cMNC with aPBMC, killing activity against the K562 cells of cMNC was augmented to the level of aPBMC when cultured with IL-2, IL-12 or IL-15. The killing activity of cMNC against CMV-uninfected and -infected fibroblasts did not increase to the level of adult PBMC by treatment with IL-2, IL-12 or IL-15. These data suggest that cord blood contains a functionally different NK cell subpopulation than that among adult NK cells.

Abstract
The purpose of this study was to estimate daily energy expenditure (EE) and daily activity factor (DAF: EE/basal metabolism - 1) of junior high school students in Japan using heart rate (HR) monitoring method. Daily activity recording and 24 hour HR monitoring were measured in all the subjects. The relational formulas between HR and oxygen consumption were obtained from bicycle ergometer test. Subjects were 112 junior high school students (68 male and 44 female) from the 1st to the 3rd year. The averages of EE (kcal/kg) of the 1st, 2nd, and 3rd year students were 54.3, 46.7, and 44.5 (kcal/kg) for males and 50.1, 44.4, and 40.5 (kcal/kg) for females respectively. In the same way DAF were 0.80, 0.61, and 0.59 for males and 0.77, 0.65, and 0.51 for females. It was shown that EE (kcal/kg) and DAF have a tendency to decrease as school year increases in both male and female students.

Abstract
Responses to a questionnaire regarding 1) dying at home, 2) being told of a diagnosis of cancer, and 3) hydration and nutrition, uses of narcotics for pain and dyspnea, oxygen treatment, antibiotics, transfusion and surgery in a near-vegetative state was obtained from 562 outpatients (73.4 +/- 8.6 years:mean +/- SD, men:women = 1.0:1.7). Dying at home was preferred by 64% and hospital death by 24%. Sixty and 65% of patients chose to be told of the diagnosis either in the last 3 months or at the early curable stage of the disease respectively, while only 53% wanted to be told precisely about their remaining estimated survival. If their spouse had terminal stage disease, 42% chose to inform the spouse of the diagnosis. Eighty percent chose palliative care, while 9.3% wished for intensive life-sustaining treatment. In a near vegetative state, tube feeding was desired by 8.7% and intravenous drip infusion by 39%; narcotics for pain or dyspnea were desired by 40 and 52%; oxygen or tracheostomy plus a respirator for dyspnea was chosen in 56 and 11% respectively; antibiotics for treatment of infection was desired by 38%; surgery for intestinal obstruction by 36 percent; transfusion for bleeding by 29%; and no treatment in any situation by 21%. Commonly expressed wishes were for a natural death, dying at home, and being told of the status of their disease, while details of palliative care were not well recognized.

Abstract
A diet high in fat and iron is known as a risk factor in cancer epidemiology. However, the details of the molecular mechanism remains to be elucidated. We examined the possible implication of lipid peroxyl radicals generated from fatty acids and heme-iron in DNA damage, and hence in the possibility of colon cancer. F344 female rats were given N-nitroso-N-methylurea six times during a 2-week period and then fed diets containing different amounts of safflower oil and hemoglobin (rich in iron) for 36 weeks; the occurrence of colon cancer was determined by H&E staining. In this animal model, simultaneous feeding of a fat diet and heme-iron produced a significant increase (P < 0.05) in the incidence of colon cancer compared with a diet without hemoglobin. Electron paramagnetic resonance and chemiluminescence studies revealed that oxidized refined vegetable oils, particularly safflower oil, readily generated lipid peroxyl radicals in the presence of various heme compounds, and the peroxyl radicals did effectively cleave DNA. Unpurified native vegetable oils contain a high amount of peroxyl radical scavengers, whereas conventional refining processes seem to reduce the levels of many valuable anti-peroxyl radical compounds abundant in plant seeds. In conclusion, lipid peroxides and heme components generate peroxyl radical species that exert DNA-cleaving activity. A plausible explanation is that lipid peroxyl radicals thus generated, which originated from routine dietary components such as fat and red meat, may contribute, at least in part, to the high incidence of colon cancer.

Abstract
Bioelectrical impedance analysis (BIA) and skinfold thickness (SF) (triceps and subscapular) methods were applied to 436 Japanese school children (228 boys and 208 girls) aged from 9 to 11 years with a one-year follow-up to determine changes in body composition. By BIA oneyear increment (Δ) of lean body mass (LBM) for boys increased significantly (p<0.01) and Δ LBM was almost equivalent to that for Δ weight (Wt). Δ Wt and Δ fat mass (FM) between the age 10 (from ages 10 to 11) and age 11 (from ages 11 to 12) groups in girls achieved statistical significance (p<0.01 and p<0.001, respectively) and Δ Wt was almost completely comprised of the Δ FM in these age groups. Δ FM in die age 11 group for girls was statistically higher than that in the age 10 group, and this obvious increase of FM in the age 11 group was presumed to be die effect of menses in consideration of die maximum oneyear increment of Ht (Δ Ht) in die age 10 group.These results of the assessment of body composition by BIA supported those of previous reports, and therefore BIA can be considered as a useful mediod to estimate changes in body composition of school children because it is simple and non-invasive and can be performed rapidly.

Abstract
PURPOSE To study a comparison of problems arising in pulmonary rehabilitation programs in North America, Europe, and Tokyo. METHODS The survey instrument was a 13-item questionnaire sent in December 1994 to institutions in North America (n = 178), Europe (n = 179), and Tokyo (n = 399). RESULTS Response rates were 51%, 40%, and 51% for North America, Europe, and Tokyo, respectively. Pulmonary rehabilitation programs were available at 56% of hospitals in North America and 74% in Europe, but at only 20% of hospitals in Tokyo. Most PRPs were conducted in an outpatient setting in North American (98%), whereas both outpatient (55%) and inpatient programs (65%) were adopted in Europe. Although the type of lung disease for which patients in both North America and Europe were referred to PRPs was mainly chronic obstructive pulmonary disease, this accounted for only 34% of referrals in Tokyo. However, referrals for primary tuberculosis sequelae (P = 0.028) and bronchiectasis (P = 0.021) were more common in Europe, similar to the situation in Tokyo. The following PRP items were available at significantly higher rates in North America than in Europe, and most were unavailable in Tokyo: family education, psychological support, nutritional instruction, treadmill, bicycle ergometer, walking training, and increasing the activity of daily living. CONCLUSION Pulmonary rehabilitation programs in North America are more multidimensional. However, target diseases differ among North America, Europe, and Tokyo. Pulmonary rehabilitation programs in Tokyo differed from those in North America and Europe and were poorly programmed. Problems arising in PRPs in the three regions include lack of staff and insufficient reimbursement.

Abstract
BACKGROUND Previous reports on experimental islet transplantation in animal models of human insulin-dependent diabetes mellitus show that islet grafts are susceptible to autoimmune destruction similar to that seen in native pancreatic islets. In this study, we demonstrated a lack of disease recurrence in diabetic BioBreeding (BB) rats after syngeneic and allogeneic islet transplantation. METHODS Four hundred to 1200 islets from BB (RT1u) and Lewis (RT1(1)) donors, isolated with stationary collagenase digestion and Ficoll density purification, were intraportally transplanted into spontaneously diabetic BB rats. The recipients received no immunologic manipulations before or after islet transplantation. RESULTS When more than 900 syngeneic islets or when more than 600 allogeneic islets were transplanted, BB recipients remained normoglycemic for over 280 days, irrespective of age at onset, duration of exogenous insulin treatment, or age at transplantation. When at least 500 islets were transplanted, the recipients survived for a long period with normoglycemia or in a noninsulin-dependent diabetic state. Upon histological examination, mononuclear cell infiltration was observed in every islet graft examined, but the severity of infiltration in most of the grafts was mild to moderate. These results indicate that the islet grafts in the BB recipients were destroyed extremely slowly. CONCLUSIONS It is conceivable that in our BB colony, a state of immunologically low responsiveness that allows diabetic animals to accept syngeneic or allogeneic islet grafts, occurs around the onset period and becomes more pronounced with aging. Our BB rat colony can be considered to be a novel substrain with unique immunological characteristics.

Abstract
The pleura is not only a mechanical envelope for the lung but also represents a crossroad for the exchange of cells and fluids. We studied ultrastructural differences in the visceral pleura of male mice in a young age group (aged 1 day, 1 week (wk), 2 wks) and an old age group (10 months (mos), 16 mos, 18 mos, 28 mos, and 30 mos), by both scanning and transmission electron microscopy. Surface microvilli (SMV) of mesothelial cells appeared to be sparse at day 1, then gradually increased in density and reached a plateau at approximately 10 mos. The length of the SMV changed in parallel with density which was confirmed by a morphometric study. After 28 mos, the SMV was partially loose, with an irregular and thin appearance. The morphological properties of pleural connective tissues, including collagen, elastin, and fibroblasts, changed in morphology with the changes in mesothelial cells; the elastic layer beneath mesothelial cells formed at 2wks and was maintained until 28 mos; collagen bundles increased in volume density throughout life, whereas cellular components including mesothelial cells, fibroblasts, and alveolar epithelial cells became atrophic with aging. From these observations, we concluded that although SMV do not have any known functions in the pleura, they change with age in a manner that likely corresponds to the changes in pleural connective tissue as well as structural changes in lung parenchyma.
