Three cases of depression fractures of the equine facial bones are described. Treatment consisted of operative exposure using large skin flaps and elevation of the fragments with and without transosseous wiring. In all cases, cosmetic and functional results were considered excellent. 相似文献

Two mares with multiple carpal bone fractures, malarticulation and degenerative joint disease were successfully treated with unilateral arthrodeses of the antebrachiocarpal, middle carpal, and carpometacarpal joints. Arthrodesis was achieved by removal of articular cartilage, autogenous cancellous bone graft, and double dynamic compression plating. In one horse, wedge ostectomy corrected the severe, acquired angular limb deformity. External coaptation supplemented the internal fixation. Postoperative complications were limited to cast sores that healed with treatment, although protracted in one horse. Both mares adapted to the "peg leg" condition and ambulated without pain by 3 months. The first mare treated survived for at least 2 1/2 years after surgery and has had at least one foal. The most recently treated mare will be bred next year. 相似文献

Infectious bovine keratoconjunctivitis (IBK) is an acute disease caused by Moraxella bovis (Mb). Several factors may predispose animals to an IBK outbreak; one commonly observed is infection with bovine herpes virus type 1 (BHV-1). The aim of this study was to investigate the dynamics of BHV-1 virus infection and its relation with clinical cases of IBK in weaned calves from a beef herd with a high prevalence of lesions caused by Mb. Sampling was carried out in six stages and included conjunctival swabs for isolating Mb as well as blood samples for identifying antibodies specific for BHV-1. A score for IBK lesions after observing each eye was determined. The findings of this study showed a high prevalence of BHV-1 virus infection (100% of animals were infected at the end of the trial); 67% of animals were culture-positive for Mb, but low rates of clinical IBK (19% of calves affected) were detected at the end of the trial. These results suggest that infection with BHV-1 did not predispose these animals to IBK, and that Mb infection produced clinical and subclinical disease in the absence of BHV-1 co-infection. 相似文献

Anti‐Müllerian hormone (AMH) is produced in the ovary, and thus, it is an excellent marker of follicle pool in females. Current interest is the clinical use of this parameter as a biomarker to assess presence or absence of an intact ovary and to diagnose ovarian remnant syndrome (ORS) following incomplete ovariohysterectomy (OHE) in bitches. The aim of this study was to evaluate serum AMH concentrations in bitches (n = 34) before and after OHE using two different commercial ELISA kits, one of which is based on detecting human AMH and the other is based on detecting human AMH and the other specified for canine AMH. Furthermore, serum AMH levels were also measured in six ORS cases to compare the diagnostic utility of the two different ELISA kits. Serum AMH concentrations measured using the human and canine kit prior to and after OHE were 0.32 ± 0.24, 0.006 ± 0.22 ng/ml (p < .001) and 12.08 ± 22.81, 9.55 ± 15.42 ng/ml (p = .868), respectively. Thus, the canine‐based kit was not able to reveal the significant drop in serum AMH levels. In conclusion, the human‐based ELISA kits successfully detected the drop in serum AMH concentrations. Reliable results can only be achieved from well‐designed ELISA kits, and AMH levels might be a useful diagnostic tool for the evaluation of presence or absence of ovaries as well as for the detection of ORS cases in bitches. 相似文献

Planting of genotype mixtures is a major strategy for the non‐chemical control of willow rust in short‐rotation coppice willows grown for biomass. In 1997 and 1998, the relative severity and spatiotemporal distribution of stem canker damage by Melampsora spp. on Salix viminalis `Bowles Hybrid' in a field trial containing monocultures and two design mixtures (random or regular) of three or five genotypes were assessed. Sphaerellopsis filum, a hyperparasite of Melampsora spp. was detected in all plots during the summer (1998) between the time of the two canker assessments. The percentage of rust pustules with this hyperparasite was initially greater in monoculture plantings than in mixtures in June, but by July, more than 92% of pustules were parasitized, irrespective of plantation design. The stem rust assessments showed that, in general, there were fewer cankers per stool in plots containing mixtures of willow genotypes compared with monoculture plantings. The distribution of rust cankers was different between monocultures and willow mixture designs, with differences between years for monocultures. 相似文献

This study examined the pharmacokinetics of steady-state phenylbutazone and single bolus intravenous gentamicin when administered together in the horse. The trial design was completed as a cross-over with seven thoroughbred horses. In the first phase each horse received 2.2 mg/kg gentamicin intravenously. After a 2-week washout, each horse received 4.4 mg/kg phenylbutazone intravenously every 24 h for 5 days. On the fourth day each horse received gentamicin as before. Plasma was harvested for gentamicin concentration determination by fluorescence polarization immunoassay and for phenylbutazone concentration determination by high-performance liquid chromatography. All gentamicin data were best approximated by a two-compartment open model using sequential, weighted non-linear regression. Pharmacokinetic parameters were calculated using model-dependent formulae. Phenylbutazone data were analysed by non-compartmental methods. Phenylbutazone induced a 49% increase in the rate of gentamicin return to the central compartment from peripheral tissues (k21 ) (P<0.05) and there was a trend to a 24% increase in k12 (P = 0.052). The gentamicin elimination half-life was decreased 23% and the Vd (area) was reduced by 26%. No induction by gentamicin of changes in phenylbutazone pharmacokinetics were detected. In summary, phenylbutazone induced changes to the rate and extent of distribution and elimination of gentamicin. Therefore, care should be exercised in the use of aminoglycosides in equine patients concurrently maintained on phenylbutazone. 相似文献

Between August 1976 and April 1980, a total of 132 canine total hip replacements using a commercially available prosthesis, were performed on clinical patients at The Ohio State University Veterinary Hospital and Berwyn Veterinary Hospital, Chicago. The technique for total hip replacement is described. Details of preoperative evaluation, the operative procedure, and postoperative care are presented. 相似文献
