A dog with visceral leishmaniasis developed rear limb edema, and distension of the caudal epigastric veins. Glomerular disease with nephrotic syndrome and hypercoagulable state was diagnosed. Sonographically there was massive thrombosis of the caudal vena cava.  相似文献   

Gonadotrophin-releasing hormone treatment in cattle: a meta-analysis of the effects on conception at the time of insemination   总被引：1，自引：0，他引：1  

WF MORGAN  IJ LEAN 《Australian veterinary journal》1993,70(6):205-209

SUMMARY Data from 40 trials described in 27 published papers were analysed by meta-analysis (pooling of data from numerous trials into a single analysis) to evaluate the effects of injecting gonadotrophin-releasing hormone (GnRH) In cattle at the time of Insemination on the risk of pregnancy. A total of 19 019 cows were involved In these studies. Analyses were stratified by trial and by the effects of dose of GnRH, type of GnRH and Insemination number (first, second or third and greater). Mantel-Haenszel analysis revealed that use of GnRH at Insemination significantly Increased the overall risk of pregnancy by 12.5% In treated cows (P < 0.05). However, Increases In risk of pregnancy were greatest (22.5%) when repeat breeders were treated. Results for use of GnRH or analogue at first service were similar, with Increased risks of pregnancy in treated cows of 5.2 and 8.0%, respectively. The risk of pregnancy tended to be higher (11.1%) when the dose of GnRH was 250 μg and when used at second Insemination (9.9%). The analyses demonstrated that while treatment at Insemination with GnRH and GnRH analogues Increased conception rates In dairy cattle, some variation In study results was attributable to the number of Inseminations after calving at which GnRH Is administered. Further efforts should be made to determine characteristics of populations of cows that have good fertility responses to GnRH and to determine the mode of action of GnRH in Increasing fertility. Meta-analysis proved to be a useful technique for evaluating the apparently conflicting results from trials and in evaluating the effect of factors such as Insemination number, dose and type of GnRH on responses to treatment.  相似文献   

Canine protothecosis: review of the literature and report of an additional case   总被引：2，自引：0，他引：2  

G Migaki  R L Font  R M Sauer  W Kaplan  R L Miller 《Journal of the American Veterinary Medical Association》1982,181(8):794-797

A review of protothecosis in dogs revealed that this malady usually begins in the gastrointestinal tract and progresses to systemic involvement. Clinical signs generally include bloody diarrhea or blood-stained feces as well as blindness, ataxia, and polyuria. Histologically, myriads of protothecal organisms in different stages of development are found in the granulomatous lesions. Two main species have been culturally identified: Prototheca zopfii and P wickerhamii. In the absence of cultural studies, species identification can be accomplished readily by immunofluorescence. The present case involved P zopfii infection in a 5-year-old female Cocker Spaniel that had bloody diarrhea, with a history of bloody diarrhea 6 months earlier.  相似文献   

Biological implications of recreational shore angling and harvest in a marine reserve: the case of Cape Creus     

Toni Font  Josep Lloret 《水产资源保护:海洋与淡水生态系统》2011,21(2):210-217

• 1. Recreational shore fishing along the coast of the marine reserve of Cap de Creus (NW Mediterranean) was studied in 2007 and 2009 based on roving creel surveys (on‐site angler surveys during which anglers' harvests are examined by the survey clerk). The study aimed to assess the biological impacts of this leisure activity on coastal fish stocks and the potential risks arising from the use of exotic baits.
• 2. Recreational shore fishers employ seven different fishing techniques, of which the bottom fishing rod (a fishing rod whose hooks, together with the bait, lie on the bottom or near it by means of a heavy weight) is by far the most widely used method (nearly 90% of observations). In total, 25 fish species were identified in the catch from the bottom fishing rod.
• 3. The estimated annual shore fishing catches (c.3 tons) are much lower than those obtained by recreational boat and spear fishing (c.20 tons each), and those from commercial (artisanal) fishing (c.50 tons). The weighted mean vulnerability index and trophic level values in the catch from the bottom fishing rod are 52.2 and 4.03, respectively.
• 4. A minimum of 43% of the baits used by the shore anglers were live, non‐native species (mostly polychaetes).
• 5. Overall, results highlight the impact of shore angling on coastal fish communities of a protected area and the increasing environmental risks arising from the use of exotic marine baits, which constitute a potential and unregulated vector of introduction of non‐native species in the Mediterranean.

Renal dysplasia in a Brie sheepdog     

A. Font  L. Ferrer  J. M. Closa  J. Mascort 《The Journal of small animal practice》1991,32(12):640-642

Renal dysplasia was diagnosed in a five-month-old female Brie sheepdog. Clinical signs included vomiting, diarrhoea, coughing, polyuria/ polydipsia, bone pain, carpal and tarsal deviation and small, irregular kidneys. Non-regenerative anaemia, azotaemia, isosthenuric urine and hyperphosphataemia were the most prominent laboratory abnormalities. Juvenile renal disease was diagnosed. Histopathological evaluation of the kidneys showed lesions of renal dysplasia.  相似文献   

Acute intrinsic renal failure and blood coagulation disorders after a snakebite in a dog     

J. Puig  M. Vilafranca  A. Font  J. Closa  M. Pumarola  J. Mascort 《The Journal of small animal practice》1995,36(7):333-336

Acute intrinsic renal failure was diagnosed in a two-year-old, male, German shepherd dog following a Vipera aspis bite. Clinical signs included depression, hypersalivation, vomiting, tachypnoea, abdominal pain, splenomegaly, oliguria with haematuria and haemolysed serum. Leucocytosis with a shift to the left, thrombocytopenia, prolonged coagulation times (activated partial thromboplastin time, prothrombin time and thrombin time), hypofibrinogenaemia, azotaemia and hyposthenuria were the most prominent laboratory abnormalities. Histopathological evaluation of the kidneys showed a discrete glomerular hypercellularity, mesangial lysis and renal tubules filled with many hyaline casts and some necrotic cells.  相似文献   

The measurements of acid detergent fibre in rapeseed by visible and near-infrared spectroscopy   总被引：1，自引：0，他引：1  

R. Font    B. Wittkop    A. G. Badani    M. Del  Río-Celestino  W. Friedt    W. Lühs  A. De  Haro-Bailón 《Plant Breeding》2005,124(4):410-412

Visible and near‐infrared spectroscopy (NIRS) calibrations for acid detergent fibre (ADF) in intact rapeseed (Brassica napus L.) were performed for two different sample volumes (10 ml, 500 seeds approximately; and 1 ml, 50 seeds approximately). The inclusion of brown and yellow‐seeded cultivars in this work has allowed the whole range of ADF currently described in the literature for this character to be covered. Chemometric techniques have been used for developing calibration equations for both procedures when measuring the two different seed sample volumes. On the basis of the coefficient of determination in the cross‐validation (R²cv) obtained for the 10 and 1 ml assays (0.80 and 0.73), and SECV/SEL ratios (2.30 and 2.57), respectively, both equations showed an accuracy sufficient for screening purposes in an ADF range from 6.80 to 13.46% dry wt, which is presented in this work.  相似文献   

Congenital hypothyroidism in Scottish Deerhound puppies     

WF ROBINSON  SE SHAW  B. STANLEY  RS WYBURN 《Australian veterinary journal》1988,65(12):386-389

Two Scottish Deerhound puppies had clinical and pathological features consistent with the diagnosis of congenital non-goitrous hypothyroidism. They were from separate litters, but were the progeny of the same sire and dam. The puppies were smaller, had shorter limbs and shorter, broader heads than their littermates. They also had histories of weakness, difficulty in walking and somnolence. A characteristic radiographic feature was the absence of epiphyseal growth centres. Both had depressed serum thyroxine (T4) levels and one did not respond to exogenous thyroid stimulating hormone. On necropsy, the thyroid glands were small, the follicles varied in size and contained little or no colloid. The adenohypophysis contained many cells with markedly vacuolated cytoplasm. It is suggested that the clinicopathological pattern is the result of a primary thyroid abnormality. Possible mechanisms include either primary thyroid hypoplasia or an unresponsiveness to thyroid stimulating hormone.  相似文献   

Pharmacokinetics of azithromycin after i.v. and i.m. administration to sheep   总被引：1，自引：0，他引：1  

Cárceles CM  Font A  Escudero E  Espuny A  Marín P  Fernández-Varón E 《Journal of veterinary pharmacology and therapeutics》2005,28(5):475-479

The pharmacokinetics (PK) of azithromycin after i.v. and i.m. injection at a single dosage of 20 mg/kg bodyweight was studied in sheep. Blood samples were collected from the jugular vein until 120 h after dosing for both routes. Plasma concentrations of azithromycin were determined by bioassay. The plasma concentration-time data of azithromycin best fitted a three-compartment model after i.v. administration and a two-compartment model with first-order absorption after i.m. administration. The elimination half-life (t(1/2lambdaz)) was 47.70 +/- 7.49 h after i.v. administration and 61.29 +/- 13.86 h after i.m. administration. Clearance value after i.v. dosing was 0.52 +/- 0.08 L/kg.h. After i.m. administration a peak azithromycin concentration (C(max)) of 1.26 +/- 0.19 mg/L was achieved at 1.24 +/- 0.31 h (t(max)). Area under the curve (AUC) were 38.85 +/- 5.83 mg.h/L and 36.03 +/- 1.52 mg.h/L after i.v. and i.m. administration respectively. Bioavailability obtained after i.m. administration was 94.08 +/- 11.56%. The high tolerability of this i.m. preparation and the favourable PK behaviour such as the long half-life and high bioavailability make azithromycin likely to be effective in sheep.  相似文献
