The purpose of the study reported here was to discuss the level of intelligibility of three-dimensional computed tomography
(3D-CT) images of clinical patients for persons who are lacking veterinary knowledge. 143 undergraduate students were participated
in this study. They were entirely unfamiliar with veterinary anatomy. A survey was conducted using the visual analog scale
method with a focus on the level of intelligibility of the 3D-CT images compared to that of the two-dimensional CT images
or radiographs. As a result, the mean value of the intelligibility of the 3D-CT image was 88.4 ± 17.8 points out of 100 points.
In clinical cases, it is very difficult for pet owners lacking veterinary knowledge to understand the clinical status of their
pets even with explanations using illustrations, radiographs, and transverse CT images. It is considered that better informed
consent and patient satisfaction will be obtained provided veterinarians make an effort towards intelligible patient education
by using 3D-CT images. 相似文献

In 2004, a damping-off symptom was found on southern star, Oxypetalum caeruleum, in Kochi Prefecture, Japan. Two Phytophthora strains with different colony patterns on potato dextrose agar were isolated, and their pathogenicity was confirmed by inoculation
of southern star plants and their reisolation from symptomatic plants. Both fungi were identified as Phytophthora palmivora based on morphology, physiology, and sequence analysis of the internal transcribed spacers of nuclear ribosomal DNA. This
is the first report of Phytophthora blight of southern star in the world. 相似文献

This study evaluated the osteoanagenetic effects of administering biodegradable gelatin β-tri calcium phosphate sponges containing mesenchymal stem cells (MSCs) and bone morphogenetic protein-2 (BMP-2) on equine bone defect. Six healthy Thoroughbred horses were used in this study. Horses were anesthetized, and skin incisions were made on all the limbs. Splint bones were exposed and a 1-cm bone defect was created in each exposed bone. Gelatin β-tri calcium phosphate sponges containing MSC and BMP-2 (MSC + BMP-2 sponge), MSC only (MSC sponge), BMP-2 only (BMP-2 sponge), or saline (saline sponge) were implanted into each bone defect at random. Defects were monitored for 16 weeks by radiography followed by computed tomography (CT) and histologic analyses. At 16 weeks, radiographic scores of MSC + BMP-2 sponge-treated defects were significantly higher than those of saline-treated defects (P = .027). Moreover, the CT value of the MSC + BMP-2 sponge group was significantly higher than that of the other groups (P = .027; P = .046; and P = .027, respectively), and the histologic score of the MSC + BMP-2 sponge group was significantly greater than that of the saline sponge group (P = .041). We conclude that MSC + BMP-2 sponge administration to bone defects accelerates bone regeneration in equines. 相似文献

Radical scavenging activities of extracts and constituents in Cornus capitata adventitious root cultures were evaluated by using 1,1-diphenyl-2-pycrylhydrazyl (DPPH) and superoxide anion radicals. Inhibitory activity against peroxidation of linoleic acid was assayed by using the thiobarbituric acid (TBA) method. Ethyl acetate and aqueous fractions were prepared from adventitious roots cultured in Murashige-Skoog liquid medium with 0.1 microM Cu(2+) (0.1CuMS) or 10 microM Cu(2+) (10CuMS). The highest scavenging activities on DPPH and superoxide anion radicals were observed in the ethyl acetate fraction from 0.1CuMS. In the inhibitory activity against linoleic acid oxidation, the ethyl acetate fraction from 10CuMS was highest among the fractions tested. The ethyl acetate fraction of adventitious roots cultured in 0.1CuMS contained mainly galloylglucoses (1,2,3,6-tetragalloylglucose and 1,2,3,4,6-pentagalloylglucose). The ethyl acetate fraction of adventitious roots cultured in 10CuMS contained mainly ellagic acid derivatives [3,3'-di-O-methylellagic acid 4-(5"-acetyl)-alpha-L-arabinofuranoside and stenophyllin H1]. Aqueous fractions prepared from both media contained iridoid glycosides (dihydrocornin and cornin). Tetra- and pentagalloylglucoses showed strong inhibitory activities (61.9 and 85.2%, respectively) against linoleic acid oxidation relative to those of butylated hydroxytoluene (BHT) (91.1%) or alpha-tocopherol (49.5%) at 50 microM concentration. Although both ellagic acid derivatives had weak activities (<50%) on DPPH and superoxide anion radical scavenging, 3,3'-di-O-methylellagic acid 4-(5"-acetyl)-alpha-L-arabinofuranoside was stronger (74.7%) than alpha-tocopherol (49.5%) in inhibiting linoleic acid oxidation at 50 microM concentration. Iridoid glycosides exhibited little activity against DPPH and superoxide anion radicals or against oxidation of linoleic acid. 相似文献

In order to introduce the Canine Behavioral Assessment and Research Questionnaire (C-BARQ), which is a standardized system for evaluating the behavioral traits of dogs, to Japan, where the environment with respect to dog ownership is thought to differ from those of the United States and Europe, we compared demographic information on dogs in the United States and Japan and examined whether similar factors could be extracted from both countries using questionnaire items of the C-BARQ. The C-BARQ was completed by 11,410, and 734 dog owners respectively in the United States and Japan, and some demographic differences were found, such as breed and neuter status. Data from completed questionnaires were subjected to factor analysis, and the resulting factors were tested for reliability. In the United States, factor analysis yielded 11 factors from 63 items that accounted for 52.9% of the common variance. In Japan, 15 factors were extracted, and these accounted for 57.0% of the common variance. The present factors for the United States were almost identical to the factors identified in a previous study, and similar factors were extracted in both countries. Therefore, the C-BARQ can function effectively as a fundamental behavioral evaluation system for dogs in Japan. 相似文献

The aim of the study was to assess the effects of changing acquisition parameters used for high-resolution in vivo magnetic resonance (MR) microscopy on image quality and scan time. The head or abdomen of 11 normal and 1 glioblastoma-bearing anesthetized BALB/c mice were imaged using a high-resolution 7.0-Tesla magnet. Scan parameters such as matrix size (MTX), slice thickness (ST), number of excitations (NEX), pulse sequence type including repetition time (TR) and echo time (TE), respiratory gating, and intraperitoneal contrast medium administration were altered to assess their actual effect on signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) as compared to calculated effects. As expected, SNR increased with increasing ST or NEX and with decreasing MTX. However, although the empirical increase in SNR was similar to that expected for increased ST, it was less than that anticipated for increasing NEX or decreasing MTX. Increasing NEX and applying respiratory gating both increased SNR and reduced the image degradation associated with respiratory motion in images of the abdomen. Intraperitoneal contrast medium administration produced a marked increase in CNR in the subject with the implanted glioblastoma, suggesting that this route is satisfactory for the enhancement of lesions disrupting the blood-brain barrier. The consequence of improving image quality in terms of spatial and contrast resolution is increased scan time. However, the actual increase in SNR when altering acquisition parameters may not be as much as predicted by theory. 相似文献
