A one-year-old, castrated male domestic short hair cat was admitted with a history of
anorexia, regurgitation and pyrexia for two days. Fever and leukocytosis were identified.
There were a large soft tissue density oval mass in the caudal mediastinum on thoracic
radiographs, a fluid-filled oval mass in the caudal mediastinum on ultrasonography, and
left-sided and ventrally displaced and compressed esophagus on esophagram. On esophageal
endoscopy, there were no esophageal abnormalities. CT findings with a fluid filled mass
with rim enhancement indicated a caudal mediastinal paraesophageal abscess. The patient
was treated with oral antibiotics, because the owner declined percutaneous drainage and
surgery. The patient was admitted on emergency with severe respiratory distress; and
ruptured abscess and deteriorated pleuropneumonia were suspected. With intensive
hospitalization care and additional antibiotic therapy, the patient had full recovery. 相似文献

Abstract. In the spring of 1992 and 1993, an epizootic with severe mortality occurred among cultured goldfish. Carassius auratus (L.), in Aichi and Nara Prefectures in Japan. A herpes-virus was isolated from moribund goldfish that induced cytopathic effects in FHM and EPC cells. The isolate was sensitive to IUdR (5-iodo-2-deoxyuridine), acid (pH 3) and ether. Transmission studies confirmed the pathogenicity of the viral isolate for goldfish while it was not pathogenic for fancy carp, Cyprinus carpio L. Diseased fish had no visible external signs except for listlessness, but internally there was softening and discolouration of the spleen and kidney, and necrotic foci in the haematopoietic tissue, splenic pulp, pancreas, and lamina propria and submucosa of the intestine. Electron microscopy revealed enveloped visions ranging from 170 to 220nm in diameter with hexagonal nucleocapsids (115–117nm edge-to-edge diameter). The disease has been designated as herpesviral haematopoietic necrosis (HVHN), and to date, is the only herpesvirus infection to be described in goldfish. 相似文献

Biotite and bentonite are phyllosilicate minerals that were originally used in
industrial applications. Several beneficial activities of them have recently been
reported, especially regulation of the immune system and antimicrobial effects. Therefore,
we investigated the immune-enhancing and bacterial clearance effects of a biotite and
bentonite mixture (BBM) on experimental infection of Salmonella enterica
serovar Typhimurium (S. Typhimurium) to determine whether the BBM could
be used as an alternative antibiotic. We administered 1% or 2% BBM as a feed supplement.
We then evaluated the bacterial clearance effects of the BBM against S.
Typhimurium. We also evaluated the immune-enhancing effect of the BBM through several
immunological experiments that included examination of the lysozyme activity,
CD4+/CD8+ T lymphocyte ratio and the T-helper type 1 (Th 1)
cytokine profile. The clinical signs of S. Typhimurium and the number of
viable bacteria in feces and tissues were significantly decreased in both BBM groups,
especially in the 2% BBM group. The BBM also markedly enhanced the lysozyme activity,
CD4+/CD8+ T lymphocyte ratio and expression levels of IFN-γ and
IL-12 in S. Typhimurium-challenged pigs. Therefore, the BBM could be a
good candidate as an alternative antibiotic that improves Th 1-specific immune responses
and the bacterial clearance effect. 相似文献

The objective of our study was to determine individual and global glomerular filtration rates (GFRs) using dynamic renal computed tomography (CT) in Beagle dogs. Twenty-four healthy Beagle dogs were included in the experiment. Anesthesia was induced in all dogs by using propofol and isoflurane prior to CT examination. A single slice of the kidney was sequentially scanned after a bolus intravenous injection of contrast material (iohexol, 1 mL/kg, 300 mgI/mL). Time attenuation curves were created and contrast clearance per unit volume was calculated using a Patlak plot analysis. The CT-GFR was then determined based on the conversion of contrast clearance per unit volume to contrast clearance per body weight. At the renal hilum, CT-GFR values per unit renal volume (mL/min/mL) of the right and left kidneys were 0.69 ± 0.04 and 0.57 ± 0.05, respectively. No significant differences were found between the weight-adjusted CT-GFRs in either kidney at the same renal hilum (p = 0.747). The average global GFR was 4.21 ± 0.25 mL/min/kg and the whole kidney GFR was 33.43 ± 9.20 mL/min. CT-GFR techniques could be a practical way to separately measure GFR in each kidney for clinical and research purposes. 相似文献

This study was carried out to investigate the effects of bamboo charcoal and bamboo vinegar as alternatives of antibiotics in the diet of fattening pigs and their influence on growth performance, immune responses and fecal microflora populations. Crossed pigs (n = 144, 79 kg body weight) were divided into 12 heads per pen, four diets and three replications. The basal diet (negative control: NC) was supplemented with 0.3% antibiotics (positive control: PC), 0.3% bamboo charcoal (BC) and 0.3% bamboo vinegar (BV). Average daily weight gain and feed efficiency were higher (P < 0.05) in PC, BC and BV. The concentration of lactate dehydrogenase and cortisol were lower (P < 0.05), but the concentration of immunoglobulin G (IgG) and IgA were higher (P < 0.05) in PC, BC and BV. Counts of coliform bacteria and Salmonella spp. were lower (P < 0.05), while the counts of fecal anaerobic total bacteria and lactic acid bacteria were higher (P < 0.05) in PC, BC and BV. A reasonable inclusion of bamboo charcoal or bamboo vinegar as antibiotics in the diet of fattening pigs leads to a better growth performance, immune responses and fecal microflora populations. The results of the present study suggest that bamboo charcoal or bamboo vinegar could be a potential additives in animal production as an alternative to antibiotics. 相似文献

An analytical method was developed and validated for the measurement of the novel analgesic and anti-inflammatory drug robenacoxib in blood and plasma of dogs and cats. To prevent nonreproducible carry-over effects, an initial solid phase extraction procedure was followed by high pressure liquid chromatography analysis for samples with concentrations in the range 500 to 20 000 ng/mL. To improve accuracy, samples of concentration 3 to 100 ng/mL were analyzed by liquid chromatography-mass spectrometry. Applying these methods, blood concentration-time profiles and pharmacokinetic variables of robenacoxib in dogs were determined in a four-phase cross-over study, which compared different routes of administration of the drug, including intravenous (i.v.) injection, oral application with and without feed, and subcutaneous (s.c.) application. After i.v. administration the mean clearance from blood was 0.81 L/kg/h, the volume of distribution was 0.77 L/kg for the elimination phase and 0.24 L/kg for steady-state, and the terminal half-life in blood was 0.63 h. Maximum blood concentrations were obtained in less than 1 h following oral or s.c. application. Absolute bioavailability was 88% after s.c. injection, 84% after oral administration to fasted dogs, but was reduced to 62% when applied orally to fed dogs. In canine and feline plasma the degree of binding of robenacoxib to plasma protein in vitro was greater than 98%. The blood:plasma concentration ratio was 0.44:1 in the dog and 0.65:1 in the cat. In conclusion analytical methods for the quantification of robenacoxib in blood and plasma in the dog and cat were developed and validated. In dogs, robenacoxib has good bioavailability after oral (84%) and subcutaneous (88%) administration. 相似文献

The aim of the present study was to investigate the effect of Eucommia ulmoides leaf (EUL) supplementation on the growth performance, blood and meat quality parameters in growing and finishing pigs. Ninety gilts (L × LW × D, 20 kg initialBW) were housed 10 per pen in a front‐open building with three replicate pens per treatment. Experimental treatment was started from the beginning of the growing stage (20 ± 3 kg) by supplementing EUL at 0(C), 3(T1) and 5% (T2) to the growing and finishing diet. Pigs were slaughtered by electrical stunning at 105 ± 3 kg live weight. Average daily feed intake (ADFI, kg/day) decreased (P < 0.05) by addition of EUL in growth performance, average daily gain (ADG, kg/day) was lower (P < 0.05) in T1 and T2 than in C. In hematology, leukocytes (WBC, 103/mm3) decreased (P < 0.05) in T1 and T2 than in C. Erythrocytes (RBC, 106/mm3), hemoglobin (HGB, g/dL) and hematocrit (HCT, %) increased (P < 0.05) in T1 and T2 than in C. Platelet (PLT, 103/mm3) was lower (P < 0.05) in T2 than in C and T1. In biochemical composition of serum, total protein (g/dL), r‐GTP (μ/L), total cholesterol (mg/dL) and triglycerides (mg/dL) were lower (P < 0.05) in T1 and T2 than in C. On longissimus dorsi muscle, crude protein was higher (P < 0.05) in T1 than in C. Crude ash was higher (P < 0.05) in T1 and T2 than in C. Yellow to blue color scale (CIE b*) in meat color was higher (P < 0.05) in T2 than in C. CIE b* in back fat color was higher (P < 0.05) in T2 than in the other treatments. In sensory evaluation scores for fresh meat, the values of meat color, fat color, drip loss and marbling were not significantly affected by addition of EUL. In cooked meat, the values of chewiness and overall acceptability were higher (P < 0.05) in T1 and T2 than in C. The results indicate that the addition of EUL affected growth performance, blood parameters and meat quality parameters in growing and finishing pigs. 相似文献
