Pharmacokinetic disposition and arthropathic potential of oral ofloxacin in dogs   总被引：2，自引：0，他引：2  

K. YOSHIDA  K. YABE  S. NISHIDA  N. YAMAMOTO  C. OHSHIMA  M. SEKIGUCHI  K. YAMADA  & K. FURUHAMA 《Journal of veterinary pharmacology and therapeutics》1998,21(2):128-132

We examined the relation between the pharmacokinetic disposition and arthropathic potential of ofloxacin, a new quinolone antibacterial agent, using both male immature (3-month-old) and mature (18-month-old) beagles. Ofloxacin was orally administered to these dogs at 20 mg/kg once daily for 8 consecutive days, and the animals were killed 2 h after the last treatment. Serum ofloxacin concentrations were repeatedly measured on days 1 and 7 by use of high-performance liquid chromatography (HPLC), and pharmacokinetic parameters were calculated. In addition, on day 8, the drug concentrations in the joint synovial fluid and humeral and femoral condyles were measured. Clinico-pathological tests of blood and serum or histopathological examination of bone specimens were also performed. Arthropathy was macroscopically observed in the cartilage surface of all immature dogs, but not in mature dogs. There were, however, no noticeable differences in pharmacokinetic parameters between the two age groups of dogs or between single and 7-day treatments. In contrast to the occurrence of arthropathic lesions, the synovial fluid and condylar drug concentrations in immature dogs was equal to or lower than those in mature dogs, suggesting that the pharmacokinetic disposition of ofloxacin may not be essential for cartilage lesions.  相似文献   

Shoot Blight and Leaf Spot of Blueberry Anthracnose Caused by <Emphasis Type="Italic">Colletotrichum acutatum</Emphasis>     

Shigenobu YOSHIDA  Takao TSUKIBOSHI 《Journal of General Plant Pathology》2002,68(3):246-248

Shoot blight and leaf spots were found on highbush blueberry trees in Tsukuba, Ibaraki, in 1999. The causal fungus was identified morphologically as Colletotrichum acutatum Simmonds ex Simmonds. This is the first report of blueberry anthracnose caused by C. acutatum in Japan. Received 16 November 2001/ Accepted in revised form 22 March 2002  相似文献

Effect of High β-Glucan Barley on Serum Cholesterol Concentrations and Visceral Fat Area in Japanese Men—A Randomized,Double-blinded,Placebo-controlled Trial     

Shimizu C  Kihara M  Aoe S  Araki S  Ito K  Hayashi K  Watari J  Sakata Y  Ikegami S 《Plant foods for human nutrition (Dordrecht, Netherlands)》2008,63(1):21-25

This study investigated whether the consumption of a diet in which high-β-glucan barley replaced rice would reduce the visceral fat area as well as the serum low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) in hypercholesterolemic Japanese men. A randomized, double-blinded, placebo-controlled intervention study was conducted in 44 hypercholesterolemic Japanese men with a body mass index (BMI) >22 kg/m². The subjects were randomly assigned to groups consuming either rice (placebo group) or a mixture of rice and pearl barley with a high β-glucan content (test group, 7.0 g β-glucan per day) for 12 weeks. Blood samples were taken, and CT scan obtained before the trial and every four weeks during the trial. The pearl barley intake significantly reduced serum concentrations of LDL-C (P = 0.041) and TC (P = 0.037) during the trial. Significant differences between the test and placebo groups were found for the visceral fat (P = 0.039), BMI (P = 0.015), and waist circumference (P = 0.011) at the end point. The consumption of pearl barley with a high β-glucan content reduces not only LDL-C but also visceral fat area.  相似文献   

Improvement of media for thermophilic ammonia-oxidizing bacteria in compost     

Chikako SHIMAYA  Tomoyoshi HASHIMOTO 《Soil Science and Plant Nutrition》2008,54(4):529-533

Thermophilic ammonia-oxidizing bacteria (AOB) have the potential to reduce ammonium emissions from commercial-scale animal waste composting operations. Two new media have been designed to culture and enumerate thermophilic AOB species. C-1 medium was designed to reflect compost composition. C-2 medium and CQ-2 medium were modified synthetic organic wastewater for the cultivation and enumeration of AOB, respectively. These new media have several advantages over the conventional medium. C-2 medium is effective for nitrification at 50°C, and C-1 and C-2 media support reasonable growth of thermophilic AOB. Furthermore, C-1 and CQ-2 media allow enumeration of thermophilic AOB during the composting process. This is the first report of the successful cultivation and enumeration of thermophilic AOB in compost. These results suggest the possibility of isolation and manipulation of novel thermophilic AOB species for environmental bioremediation.  相似文献   

Basic characterization of 90 kDa heat shock protein genes HSP90AA1, HSP90AB1, HSP90B1 and TRAP1 expressed in Japanese quail (Coturnix japonica)     

Kohji NAGAHORI  Shigehisa IWAMOTO  Akira MARUYAMA  Shingo SUZUKI  Kazuyoshi HOSOMICHI  Takashi SHIINA  Hiromi HARA  Yutaka YOSHIDA  Kei HANZAWA 《Animal Science Journal》2010,81(4):513-518

In the current study, we describe four novel members of the 90 kDa heat shock protein (HSP90) family expressed in Japanese quail, Coturnix japonica. The coding regions of the genes, CjHSP90AA1, CjHSP90AB1, CjHSP90B1 and CjTRAP1, exhibited more than 94% similarity to their related genes in chicken. The putative proteins encoded by these quail genes contained motifs considered essential for HSP90 gene function. In addition, the predicted proteins were more similar to HSP90AA1, HSP90AB1, HSP90B1 and TRAP1 proteins expressed in vertebrates than they were to other members of the HSP90 family. Exon numbers of CjHSP90AA1 (11), CjHSP90AB1 (12) or CjTRAP1 (18) are the same as the chicken and mammalian orthologs. Furthermore, gene order in the regions surrounding CjHSP90AB1 and CjTRAP1 has been preserved, providing evidence that the genomic regions were orthologous to HSP90‐containing regions in the chicken genome. The promoter regions of the genes also contained conserved motifs identified in related genes of chicken. However, the nucleotide sequences of the 5′‐flanking region of these genes were highly polymorphic. We also found that CjHSP90AA1 exhibited a robust response to heat shock treatment. Taken together, the data suggest that CjHSP90AA1, CjHSP90AB1, CjHSP90B1 and CjTRAP1 encode orthologs of HSP90AA1, HSP90AB1, HSP90B1 and TRAP1, respectively.  相似文献   

Bacteriological survey of feces from feral pigeons in Japan     

Tanaka C  Miyazawa T  Watarai M  Ishiguro N 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2005,67(9):951-953

Some public areas in Japan such as parks and gardens can be highly contaminated with pigeon feces. We examined levels of four bacterial contaminations in fecal samples from feral pigeons in 7 prefectures. We isolated Salmonella Typhimurium and S. Cerro from 17 (3.9%) of 436 samples, as well as Mycobacterium spp. including M. avium-intracellulare complex from 29 (19.0%) of 153 samples. The polymerase chain reaction detected Chlamydia psittaci and C. pecorum in 106 (22.9%) of 463 samples, but E. coli O-157 was not isolated from any of the samples. Our results indicate that pigeon feces are a source of several zoonotic agents for birds, animals and humans.  相似文献   

Response of plasma cortisol and progesterone after ACTH challenge in ovariectomized lactating dairy cows     

Yoshida C  Nakao T 《The Journal of reproduction and development》2005,51(1):99-107

Shortened and weakened estrous expressions could be one of the causes of poor heat detection rate. Non-specific acute stresses are assumed to depress expression of estrus by an increase of plasma progesterone which may originate from the adrenal cortex. The objective of the present study was to examine whether the adrenal cortex can secrete significant amounts of progesterone in response to exogenous adrenocorticotropic hormone (ACTH) in lactating cows. Four cows had estrus synchronized and were ovariectomized in the luteal phase. The cows were given 25 IU ACTH through an indwelling catheter 5 h after catheterization. Blood samples were collected at an interval of 30 min. In 3 of the 4 cows, plasma progesterone concentrations increased significantly 0.5-1.5 h after the first ACTH challenge with a mean peak value of 4.2 +/- 0.4 (S.D.) ng/ml. A similar response was also observed after the second ACTH challenge. Peak plasma progesterone concentrations in the 3 cows after first ACTH challenge were comparable with the progesterone values in the luteal phase of each cow. The results suggest that lactating cows have the capability to secrete a significant amount of progesterone from the adrenal cortex.  相似文献
