The lesions of histoplasmosis in dogs in Japan differ from those in dogs in North America. Affected dogs in Japan have had multiple granulomatous or ulcerated foci in skin or gingiva and have not had pulmonary or gastrointestinal lesions. The present report introduces a polymerase chain reaction (PCR) diagnosis of canine histoplasmosis and the characteristic of disease in Japan. The surgically removed skin ulcerate samples from a 5-years-old female Shiba-inu native to Japan without traveling out of the country were evaluated. Tissue samples had many yeast-like organisms in the macrophages. DNA was extracted from paraffin-embedded tissue samples. A nested PCR technique was applied. The detected sequence of the internal transcribed spacer of ribosomal RNA gene had 99.7% in homology with Ajellomyces capsulatus (the teleomorph of Histoplasma capsulatum). Clinical manifestations, historical background of equine epizootic lymphangitis in Japan, and a human autochthonous case of histoplasmosis farciminosi indicated that this dog might have been infected with H. capsulatum var. farciminosum as a heteroecism. 相似文献

The effect of linoleic acid-albumin (LAA) supplementation to the media for IVM, enucleation, and activation on the developmental potential of bovine embryos produced by nuclear transfer (NT) into frozen-thawed cytoplasts was investigated. Blastomeres derived from morulae was placed in the perivitelline space of frozen-thawed cytoplasts, which were then fused by a DC pulse. The proportion of fused embryos was similar between groups with and without LAA (87 vs. 90%). The proportion of development to blastocysts of NT embryos derived from the media with LAA (14%) was higher than that without LAA (4%), indicating that LAA treatment of bovine oocytes during IVM, enucleation and activation can improve the ability of such cytoplasts after freezing and thawing to develop into blastocysts after NT. 相似文献

Analyses of patrol videos that record the circumstances of race accidents was made. Many of the serious accidents that occur in the course of races involve fracture or dislocation of the component bones of the fetlock joint. A large percentage of these occurred on the leading leg, regardless of whether the horses were running clockwise or counterclockwise direction. Many of these accidents occurred during changes in lead, with the accidents occurring at the moment when a limb made contact with the ground. Differences in the location of musculoskeletal injuries were observed in accidents that occurred in the straightaway portion of the track, while moving out of turns to the straightaway; and while in the turn. 相似文献

Causative agent of rabbit haemorrhagic disease (RHD) was purified by CsCl density gradient centrifugation from the liver homogenate of rabbits infected with RHD virus which originated from Korea. The viral particles were 35-40 nm in diameter, and had hollow depressions on their surface. Protein A-gold immunoelectron microscopy clearly showed that the convalescent antisera of diseased rabbits reacted specifically with the virus particles. SDS-PAGE and Western blot analyses demonstrated that the structural protein of the virus was composed of a single major polypeptide of 63 kD. These findings indicate that the causative agent of RHD, tentatively named as picornavirus in Korea, belongs to calicivirus. 相似文献

The aim of this study was to determine whether 2,4-thiazolidinedione (2,4-TZD) influences the effects of peripheral insulin action in steers given recombinant bovine tumor necrosis factor (TNF) alpha (rbTNF). Steers were treated once daily for 9 d (d0 - d8) with either s.c. injection of rbTNF (2.5 microg/kg), rbTNF + i.v. injection of 2,4-TZD (2.0 mg/kg), or s.c. injection of saline (control). The plasma glucose, NEFA, and insulin concentrations in the rbTNF-treated group increased compared to those in the control and rbTNF + 2,4-TZD groups, whereas glucagon concentration decreased. A single i.v. injection of insulin (0.2 U/kg), glucose (112.5 mg/kg), or growth hormone (GH)-releasing hormone (GHRH) (0.25 microg/kg) was performed on d4, d6, and d8, respectively. In the insulin challenge, the net area under the glucose curve (AUC) was smaller in the rbTNF group than in the control and rbTNF + 2,4-TZD groups. In the glucose challenge, the net insulin AUC was smaller in rbTNF + 2,4-TZD group than in rbTNF group. In the GHRH challenge, there was no difference in GH responses to GHRH between the rbTNF and rbTNF + 2,4-TZD groups, respectively. We conclude that 2,4-TZD treatment partially reverses the impairment of peripheral insulin action caused by rbTNF injection in steers. 相似文献

This study aims to investigate recent practices on water allocation and cultivation in the Upper East Bank of the Chao Phraya Delta in Thailand, by using data collected by RID local offices, questionnaires, and analyses of satellite images. As a result, we have identified the advantage that upstream areas of irrigation canals have enjoyed, namely the preferential water allocation over the downstream areas. This advantage was strongly associated with the intensive cropping patterns of rice: the upstream areas were estimated to conduct almost continuous rice cultivation throughout a year. In addition, the intensive rice cultivation would partly be supported by water from private shallow wells, which were mostly concentrated in the upstream areas of main canals. Those shallow wells would be used at the beginning of the dry season and in drought years, when farmers could not expect water supply from irrigation canals. The result indicated that the conjunctive use of surface and ground water would be practiced in this region. 相似文献

Abstract – A segment of the Shibetsu River was restored to reconstruct the ecological condition of the previously canalized river stretch to a more natural, meandering state. In this study, we investigated the upstream migration of chum salmon ( Oncorhynchus keta ) using radio transmitters to track the horizontal position of fish and data loggers to detect the vertical swimming depth of fish, simultaneously. The monitored salmon travelled near the bottom of the water column and along the riverbanks, and tended to hold in deep, slow current areas in the canalized river. In the restored segment, the fish swam at more shallow depths and against stronger currents. Although the three tracked fish all reached the confluent point and chose to enter the restored segment, they did not remain in the segment for long. This indicates that the restored area facilitates the upward migration of the chum salmon. 相似文献
