Abstract. During the period from 1965 to 1980, 263 Vibrio anguillarum strains from ayu, Plecoglossiis altivelis (Temminck & Schlegel), two from rainbow trout. Salmo gairdneri Richardson, and two from eel, Anguilla japonica (Temminck & Schlegel), were collected from fish suffering from vibriosis in various parts of Japan. On the basis of cross-agglutination and cross-absorption tests with thermostable (O) antigens, six distinct serotypes (A, B, C, D, E and F) were established among 12 selected strains of V. anguillarum . 241 strains isolated from ayu and two strains from rainbow trout belonged to serotype A, six strains from ayu and one strain from eel to serotype B, 12 strains from ayu to serotype C, three strains from ayu to serotype D, one strain from ayu to serotype E, and one strain from eel to serotype F. V. anguillarum strains belonging to serotypes D, E and F have not been detected from ayu, rainbow trout and eel since 1973; these serotypes appear to be minor types. V. anguillarum strain NCMB 6 and 1669 belong to our serotype A and V. anguillarum 813 to our serotype C. 相似文献

The effects of 1.0, 1.5, and 2.0 minimum alveolar concentration (MAC) of sevoflurane on hemodynamic, pulmonary and blood chemistry variables were measured during spontaneous and controlled ventilation in healthy horses. Sevoflurane was the only anesthetic drug administered to the horses. In a dose-dependent manner, sevoflurane significantly decreased ( P <.05) mean arterial blood pressure, cardiac output, and stroke volume. There was a progressive decrease in peripheral vascular resistance and an increase in heart rate as the concentration of sevoflurane was increased, but the differences were not significant. During spontaneous ventilation there was a dose-dependent decrease in respiratory rate that caused a decrease in the minute volume. As the dose of sevoflurane increased, the arterial carbon dioxide tension also increased ( P <.05). All blood chemistries remained within normal limits. Recovery from anesthesia was without incident. In conclusion, sevoflurane induces a dose-dependent decrease in hemodynamic variables and pulmonary function in horses that is not greatly different from that of other approved inhalant anesthetics. 相似文献

DENSIMETRIC FRACTIONATION OF SOIL ORGANO-MINERAL COMPLEXES 总被引:2,自引:0,他引:2

A rapid, simple, and precise density fractionation of soil mineral-organic complexes, suitable for routine work, is described. Special features of the method are: low sample weight, use of glass-fibre paper to collect the lighter fractions, and use of a modified Walkley-Black procedure to determine the carbon content of the light fraction in test tubes. Density-distribution curves of organo-mineral soil complexes are shown to yield useful basic information on degradation processes of soil organic matter caused by cultivation. The results suggest that complexes between clay and organic matter tend to build up preferentially with a certain proportion between the components. 相似文献

Anterior temporal lobectomy (ATL) is a surgical procedure for drug-resistant mesial temporal lobe epilepsy that is commonly performed in human medicine. The purpose of this study was to determine whether ATL-like surgery, i.e., removal of the amygdala and hippocampal head, is possible in dogs, and to investigate its safety and postoperative complications. Eight healthy beagles underwent ATL-like surgery and were observed for 3 months postoperatively. Samples from the surgically resected tissues and postmortem brain were evaluated pathologically. The surgical survival rate was 62.5%. The major postoperative complications were visual impairment, temporal muscle atrophy on the operative side, and a postoperative acute symptomatic seizure. Due to the anatomical differences between dogs and humans, the surgically resected area to approach the medial temporal structures in dogs was the ventrolateral part of the temporal lobe. Therefore, the ATL-like surgery described in this study was named “ventrolateral temporal lobectomy” (VTL). This study is the first report of temporal lobectomy including amygdalohippocampectomy in veterinary medicine and demonstrates its feasibility. Although it requires some degree of skill, VTL could be a treatment option for canine drug-resistant epilepsy and lesions in the mesial temporal lobe. 相似文献

Bacteriological properties and DNA-DNA homology values were compared among the pathogen causing bacterial shoot blight of
pear (BSBP) isolated in 1994–1996, Erwinia amylovora isolated outside of Japan, and other Amylovora group bacteria. Bacteriological properties of BSBP strains were identical
to those of E. amylovora in the majority of tests, but differed distinctively in several tests, including hydrolysis of esculin and acid production
from salicin, etc. BSBP strains differed from the others in the Amylovora group in many other tests. DNA homology among the strains of BSBP
ranged from 85 to 103% and from 83 to 110% among strains of E. amylovora. In contrast, the values between BSBP strains and E. amylovora strains were 55 to 81%, while those between BSBP strains and other Amylovora group strains were 42% or less. We consider,
therefore, that the BSBP pathogen may well be included in E. amylovora at the species level. E. amylovora, including BSBP strains, however, can be classified into four biovars based on differences in nine tests such as growth factor
requirements and crater formation on high sucrose medium. Namely, there are two biovars from Maloideae sources, one from Rubus idaeus, and one from the source of BSBP in Hokkaido. The presence of these biovars suggests a correlation with geographical, serological,
and pathogenic differentiations in the species of E. amylovora. The BSBP pathogen in Hokkaido was identified as E. amylovora bv. 4 which is distinct from E. amylovora bv. 1, 2 and 3 isolated in countries outside of Japan.

Ischemic acute kidney injury (AKI) is the most key pathological event for accelerating
progression to chronic kidney disease through vascular endothelial injury or dysfunction.
Thus, it is critical to elucidate the molecular mechanism of endothelial protection and
regeneration. Emerging evidence indicates that bone marrow-derived cells (BMCs) contribute
to tissue reconstitution in several types of organs post-injury, but little is known
whether and how BMCs contribute to renal endothelial reconstitution, especially in an
early-stage of AKI. Using a mouse model of ischemic AKI, we provide evidence that
incorporation of BMCs in vascular components (such as endothelial and smooth muscle cells)
becomes evident within four days after renal ischemia and reperfusion, associated with an
increase in stromal cell-derived factor-1 (SDF1) in endothelium and that in
CXCR4/SDF1-receptor in BMCs. Notably, anti-CXCR4 antibody decreased the numbers of
infiltrated BMCs and BMC-derived endothelium-like cells, but not of BMC-derived smooth
muscle cell-like cells. These results suggest that reconstitution of renal endothelium
post-ischemia partially depends on a paracrine loop of SDF1-CXCR4 between resident
endothelium and BMCs. Such a chemokine ligand-receptor system may be attributable for
selecting a cellular lineage (s), required for renal vascular protection, repair and
homeostasis, even in an earlier phase of AKI. 相似文献
