BACKGROUND: In order to know the relationships between mugwort pollinosis and oral allergy syndrome (OAS), an etiological study was performed at Muroran City, where mugwort is the most frequent cause of pollinosis. METHODS: Allergic rhinitis patients positive to serum IgE to birch, mugwort or grass pollen visited to the outpatient-clinic of Otorhinolaryngology of Muroran City General Hospital from 1998 to 2002, were studied by a questionnaire concerning a past-history of OAS. RESULTS: The prevalence of OAS was significantly higher in patients positive to serum IgE antibody specific to birch pollen or mugwort pollen than those negative to each pollen-specific antibody (birch; 54.5 vs 23.5%, p<0.0001, mugwort; 41.0 vs 21.5%, p<0.01). The main causative foods were fruits of rose family in patients with only birch pollen-specific IgE antibody, and were those other than rose family, such as kiwi, melon, orange, celery and onion in those with only mugwort pollen-specific IgE antibody. The patients group with high Lumiward score to mugwort pollen tended to include severe OAS cases. CONCLUSION: A close relationship was suggested between mugwort pollen sensitization and OAS. 相似文献

PURPOSE: To analyze the effect of total higher-order aberrations (HOAs) on the range of accommodation in pseudophakic eyes and the size of near-vision optotypes. SETTING: Department of Ophthalmology, Nara Medical University, Nara, Japan. METHODS: The study comprised 30 patients (44 eyes) who were diagnosed with cataract at Nara University of Medical Science Hospital and Municipal Oyodo Hospital. Inclusion criteria included no other eye disorder and a best corrected distance acuity of 20/20 or better 1 month after cataract surgery. All patients had small-incision phacoemulsification followed by in-the-bag implantation of a monofocal intraocular lens (SA60AT, Alcon). All incisions were self-sealing. Accommodation in pseudophakic eyes was measured by the lens-loading method in an examination room under constant illumination. Ocular HOAs were measured using the KR-9000PW Hartmann-Shack wavefront analyzer (Topcon). RESULTS: The mean patient age was 75.8 years +/- 5.4 (SD) (range 64 to 83 years). The Pearson correlation coefficient (r) showed a significant positive correlation between the range of accommodation and Z7 (vertical coma) for a 4.0 mm pupil using the 1.0 near-vision optotype. There was a significant negative correlation between the range of accommodation and Z12 (spherical aberration) for a 4.0 mm pupil using the 1.0 near-vision optotype (r = .311, P = .040 for Z7;r = -.365, P = .015 for Z12). No other parameter was significantly correlated with the range of accommodation. CONCLUSIONS: Measurement of accommodation in pseudophakic eyes by the lens-loading method using the 1.0 near-vision optotype showed that eyes with larger vertical coma aberrations achieved a larger range of accommodation. In contrast, eyes with larger spherical aberrations had smaller amounts of accommodation. The size of the near-vision optotype may affect accommodation analysis in pseudophakic eyes. 相似文献

Microtubule disassembling agents (MDAs) such as colchicine (COL) and vincristine sulfate (VCR) are known to be cardiotoxic. However, few attempts have been made to histopathologically examine cardiac lesions induced by MDAs. In this study, we endeavored to induce myocardial injury in rats by administering MDAs and to clarify the morphological features of these myocardial lesions. Male rats were intravenously administered COL (1.00 or 1.25 mg/kg for 2 days at single daily doses) or VCR (0.50 or 0.75 mg/kg for 2 days at single daily doses). The day after administration, hearts were excised and examined histopathologically, immunohistochemically and electron microscopically. Degeneration and necrosis of myocardial cells with vacuolation were observed in rats administered COL at 1.25 mg/kg or VCR at 0.75 mg/kg. Electron microscopic examination revealed vacuoles in swollen mitochondria. Moreover, there were cells showing pyknosis and karyorrhexis in the interstitium. TUNEL and immunohistochemical staining for endothelial cells and electron microscopic examination identified the apoptotic cells in the interstitium to be vascular endothelial cells. These vascular endothelial lesions were induced by lower doses of MDAs than were myocardial lesions. Furthermore, common sites of cardiac lesions induced by MDAs had almost the same distribution as areas positive for pimonidazole, a marker of hypoxia. These findings indicate that MDAs occasionally damage mitochondria in myocardial cells, and suggest that these changes involve microcirculatory dysfunction induced by endothelial cell injury. 相似文献

Objective
To determine the influence of the Kuchi-kara Taberu (KT) index on rehabilitation outcomes during hospitalized convalescent rehabilitation.Design
A historical controlled study.Setting and Participants
A rehabilitation hospital.Participants
Patients who were admitted to a convalescent rehabilitation ward from June 2014 to May 2017.Measures
Patients’ background characteristics included age, sex, nutritional status, activities of daily living (ADL) assessed using the Functional Impedance Measure (FIM), dysphagia assessed using the Functional Oral Intake Scale (FOIS), and reasons for rehabilitation. The following values before (control group) and after initiation of the KT index intervention period (intervention group) were compared: gain of FIM, length of stay, accumulated rehabilitation time, discharge destination, gain of FOIS, gain of body weight (BW), and nutritional intake (energy and protein).Results
Mean age was 76.4 ± 12.3 years (n = 233). There were no significant differences in the baseline characteristics of the patients at admission between the control and intervention groups, except for reason of rehabilitation. The intervention group demonstrated statistically higher values for the total (P = .004) and motor FIM gain (P = .003), total (P = .018) and motor FIM efficiency (P = .016), and FOIS gain (P < .001), compared with values in the control group. The proportion of patients returning home was statistically more frequent in the intervention group compared with that in the control group (73.4% vs 85.5%, odds ratio 2.135, 95% confidence interval [CI] 1.108-4.113, P = .022). Multivariate analyses indicated that intervention using the KT index was a significant independent factor for increased FIM gain (β coefficient = 0.163, 95% CI 1.379-8.329, P = .006) and returning home (adjusted odds ratio 2.570, 95% CI 1.154-5.724, P = .021).Conclusions/Implications
A rehabilitation program using the KT index may lead to improvement of inpatient outcomes in post-acute care. Further prospective research is warranted to confirm the efficacy of this program. 相似文献8.

OBJECTIVES: The aim of this study was to investigate the effects of rapid electrical stimulation (RES) of contraction on the expression of connexin (Cx)43 gap junction in neonatal rat cultured ventricular myocytes and the consequent changes of conduction properties. BACKGROUND: The expression and distribution of gap junctions in cardiac muscle can be changed readily under a variety of pathological conditions because of dynamic turnover of Cxs. The effects of RES of contraction on gap junction remodeling are not well understood. METHODS: Neonatal rat ventricular myocytes cultured for five days were subjected to RES (field stimulation) at 3.0 Hz for up to 120 min. RESULTS: Rapid electrical stimulation resulted in a significant upregulation of Cx43 (by approximately 1.5-fold in protein and by approximately 1.9-fold in messenger ribonucleic acid at 60 min). Immunoreactive signal of Cx43 was also increased. Angiotensin II (AngII) content was increased significantly by RES >15 min. Phosphorylated forms of extracellular signal-regulated protein kinase (ERK), c-Jun NH(2)-terminal kinases, and p38 mitogen-activated protein kinases (MAPKs) were all increased dramatically by RES with peaks at 5 - 60 min. Propagation of excitation was visualized by extracellular potential mapping by using a multiple electrode array system. Conduction velocity was increased significantly by RES for 60 to 90 min (25% - 27% increase). Treatment of myocytes with losartan (100 nmol/l) prevented most of these effects of RES; RES-induced upregulation of Cx43 was also prevented by specific inhibitors for ERK and p38 MAPKs. CONCLUSIONS: A short-term RES causes upregulation of Cx43 in cardiomyocytes and a concomitant increase of conduction velocity, mainly through an autocrine action of AngII to activate ERK and p38 MAPKs. 相似文献

Acaryochloris marina is a unique cyanobacterium that is able to produce chlorophyll d as its primary photosynthetic pigment and thus efficiently use far-red light for photosynthesis. Acaryochloris species have been isolated from marine environments in association with other oxygenic phototrophs, which may have driven the niche-filling introduction of chlorophyll d. To investigate these unique adaptations, we have sequenced the complete genome of A. marina. The DNA content of A. marina is composed of 8.3 million base pairs, which is among the largest bacterial genomes sequenced thus far. This large array of genomic data is distributed into nine single-copy plasmids that code for >25% of the putative ORFs. Heavy duplication of genes related to DNA repair and recombination (primarily recA) and transposable elements could account for genetic mobility and genome expansion. We discuss points of interest for the biosynthesis of the unusual pigments chlorophyll d and α-carotene and genes responsible for previously studied phycobilin aggregates. Our analysis also reveals that A. marina carries a unique complement of genes for these phycobiliproteins in relation to those coding for antenna proteins related to those in Prochlorococcus species. The global replacement of major photosynthetic pigments appears to have incurred only minimal specializations in reaction center proteins to accommodate these alternate pigments. These features clearly show that the genus Acaryochloris is a fitting candidate for understanding genome expansion, gene acquisition, ecological adaptation, and photosystem modification in the cyanobacteria. 相似文献
