To elucidate the effect of a large dose of di (2-ethylhexyl) phthalate (DEHP), a plasticizer and peroxisome proliferator-activated receptor-α (PPARα) agonist, on hepatic peroxisomes, we orally administered 1,000 mg/kg/day, once daily, to 3 male and 4 female cynomolgus monkeys for 28 days consecutively. Light-microscopic and electron microscopic examinations of the liver were carried out in conjunction with measurement of the hepatic fatty acid β-oxidation system (FAOS), carnitine acetyltransferase (CAT) and carnitine palmitoyltransferase (CPT) activities, which are peroxisomal and/or mitochondrial enzyme activities. Electron microscopically, enlargement of the mitochondria was observed with lamellar orientation of the cristae along the major axis. Although the number of peroxisomes showed a tendency to increase when compared with those in a biopsied specimen before treatment, no abnormality in morphology was observed. A slight increase in CPT activity was noted at termination. No changes were noted in hepatic FAOS or CAT activity. In conclusion, although repeated oral treatment of cynomolgus monkeys with a large dose of DEHP induced a subtle increase in the numbers of peroxisomes with slight enlargements of the mitochondria, this low-sensitivity response to peroxisome proliferators in cynomolgus monkeys was considered to be closer to the response in humans than that in rodents. 相似文献

A 5-month-old female Citron-crested Cockatoo (Cacatua sulphurea citrinocristata) that was born and hand-reared in Japan died with suspected proventricular dilatation disease (PDD). Macroscopic and microscopic examinations of the bird revealed characteristic features of PDD, i.e., distention of the proventriculus and infiltration of lymphocytes and plasma cells in ganglia of various organs and in central and peripheral nerves. A linkage of this PDD case to infection with avian bornavirus (ABV) was documented by RT-PCR amplification of the virus genomes from the affected bird. Phylogenetic analysis revealed that the ABV identified in this study clustered into the genotype 2, which is one of the dominant ABV genotypes worldwide. To the best of our knowledge, this is the first report of a natural case of PDD associated with ABV infection in Japan. 相似文献

This study aimed to investigate the effects of whey protein hydrolysate (WPH) on the growth and immunity of mouse pups in artificial rearing (AR) system. Mouse pups were reared in the AR system with artificial milk including 5% WPH (AR with WPH) or not (AR without WPH), and the remaining pups were reared by their mother (dam) for 14 days after birth. The body weight change and body weight gain rates in the AR with WPH group were significantly higher than those observed in the AR without WPH group and similar to those in the dam group. Moreover the feed and protein efficiencies in the AR with WPH group were significantly higher than those of the AR without WPH group. In addition, the supplement of WPH in the AR system was shown to significantly elevate the number of CD3+CD8+, B220+CD19+, IA/IE+CD11c+, and CD11b+ in the thymocyte and/or splenocyte, and the thymus weight. Furthermore, MALDI‐TOF/MS analysis identified the amino acid sequences corresponding to some peptides, and indicated that VRTPEVDDE had the highest relative intensity among the peptides from tested WPH. Therefore, WPH would be required to not only promote growth, but also exert immunomodulatory activities in mouse pups in AR system. 相似文献

Botrytis aclada and Botrytis allii, associated with onion gray-mold neck rot and isolated in Hokkaido, were tested for sensitivity to benzimidazole. Of the B. aclada strains, 59% were highly resistant and the remaining 41% were sensitive; all strains of B. allii were sensitive. Resistant strains were widespread in Hokkaido. We analyzed the sequences of the β-tubulin gene of resistant strains and detected the replacement of glutamic acid (GAG) by lysine (AAG) at codon 198. This is the first report of benzimidazole resistance in B. aclada. This study revealed a difference in fungicide sensitivity between the two Botrytis species.

Lactate dehydrogenase (LDH) in blood is measured using the Japanese Society of Clinical Chemistry (JSCC) method in Japan and the International Federation of Clinical Chemistry (IFCC) method in other countries. In human clinical practice, the IFCC method replaced the JSCC method due to international standardization. Moreover, veterinary LDH measurement will also eventually shift to the IFCC method. However, the relationship between the IFCC and JSCC methods for LDH in various animals and whether they can be equated or not have not yet been investigated. This study aimed to present the changes in measurements in canines and felines after switching to the IFCC method. The plasma LDH activity of canines (N=177) and felines (N=115), who visited a secondary care veterinary clinic, was measured using the JSCC and IFCC methods. The IFCC/JSCC ratio was <1.0 in 85% of canines and 88% of felines, indicating that the IFCC method tended to show lower values than the JSCC method, presumably because LDH5 is dominant among the LDH isozymes in canines and felines. The increase in the systematic errors of both assays was in the high value range, with some samples exceeding the error tolerance from near the upper end of the reference range. When switching to the IFCC method for LDH measurement in canines and felines, each institution should consider whether the reference range and clinical diagnostic values established by the JSCC method are appropriate for continued use. 相似文献
