Nonsurgical management of canine obstructive urolithopathy     

C A Osborne  D J Polzin 《Veterinary Clinics of North America: Small Animal Practice》1986,16(2):333-347

Obstruction to urine outflow is a common complication of urolithiasis. However, varying degrees of recovery of renal function may occur following examination of the cause of obstruction. Therefore, in the absence of conclusive evidence of irreversible dysfunction, one should consider efforts to decompress the urinary tract and to eliminate the cause of obstruction. Nonsurgical methods that may be used for management of obstructive urolithiasis include cystocentesis, palpation, urohydropropulsion, and catheterization.  相似文献

Malignant Sertoli Cell Tumour in a Young Simmenthal Bull – Clinical and Pathological Observations     

KL Jensen  L Krag  GB Boe‐Hansen  HE Jensen  H Lehn‐Jensen 《Reproduction in domestic animals》2008,43(6):760-763

Tumours are rare in the bovine testicle. A case of malignant Sertoli cell tumour in a 29‐month‐old Simmenthal bull that was hospitalized with a history of severe unilateral scrotal swelling is reported. On inspection and palpation, the scrotal sac was found enlarged with fluctuant content in the right side. The right testicle was enlarged, hard and indolent. Also the right plexus pampiniformis and funiculus spermaticus were enlarged. Sonograms revealed severe changes in the right testicle with a loss of homogeneity and multiple hyperechogenic areas. After slaughter, the scrotum with testicles were removed and evaluated pathologically. On section, the right testicle contained areas of necrosis, haemorrhage, and mineralization. Histology showed Sertoli cells in tubular structures surrounded by dense fibrous stroma replacing normal testicular tissue. Both lymphatic and blood vessels were infiltrated by neoplastic cells. Immunohistochemically, the neoplastic cells stained positive for vimentin and negative for cytokeratin and S‐100. Based on the pathological observations a diagnosis of right‐sided malignant Sertoli cell tumour with vascular invasion and hydrocele was established.  相似文献

A clinical trial of a topical preparation of miconazole, polymyxin and prednisolone in the treatment of otitis externa in dogs   总被引：3，自引：0，他引：3  

VP STUDDERT  KL HUGHES 《Australian veterinary journal》1991,68(6):193-195

A topical preparation containing miconazole, polymyxin and prednisolone was shown to be more effective in the treatment of otitis externa in 167 dogs than 2 other ear preparations containing antibiotics, an antimycotic and a corticosteroid. With miconazole, polymyxin and prednisolone, the recurrence rate was 26.7% compared with 72.6% and 54.3% when the other products were used. The mean duration of treatment required to achieve resolution of clinical signs was 9.6 days, compared with 12.2 days and 13.0 days and no cases failed to respond to treatment, compared with 17.7% and 14.3%. Malassezia canis alone (71%) or in association with bacteria (18%) was recovered from 44 of 49 ears cultured.  相似文献

Enhanced diapycnal mixing by salt fingers in the thermocline of the tropical Atlantic   总被引：1，自引：0，他引：1  

Schmitt RW  Ledwell JR  Montgomery ET  Polzin KL  Toole JM 《Science (New York, N.Y.)》2005,308(5722):685-688

Diapycnal mixing plays a significant role in the ocean's circulation and uptake of heat and carbon dioxide, but has not been quantified in salt finger-driven thermohaline staircases. We recently performed a tracer release experiment in the western tropical Atlantic staircase at approximately 400 m depth. The observed dispersion implies an effective diapycnal diffusivity for tracer and salt of 0.8 to 0.9 x 10(-4) m2/s. Temperature microstructure data interpreted in terms of a vertical production-dissipation balance yields a smaller effective diffusivity for heat of 0.45 (+/- 0.2) x 10(-4) m2/s, consistent with salt fingers and well above the mixing ascribable to mechanical turbulence.  相似文献

Serum chlortetracycline concentrations in parrots fed medicated seed diets     

KL WARD 《Australian veterinary journal》1997,75(8):558-560

Various seed diets containing chlortetracycline were fed to large and small parrots to evaluate serum chlortetracycline concentrations. The substitution of dehulled sunflower seed for whole sunflower in the seed mix may have resulted in higher chlortetracycline concentrations in cockatoos and parrots. The serum chlortetracycline concentration achieved for all diets was less than the goal of 1 μg/mL, but the concentrations attained may be useful for therapy.  相似文献
