OBJECTIVE: To determine whether hyperbaric oxygen treatment (HBOT) would affect incorporation of an autogenous cancellous bone graft in diaphyseal ulnar defects in cats. ANIMALS: 12 mature cats. PROCEDURE: Bilateral nonunion diaphyseal ulnar defects were created in each cat. An autogenous cancellous bone graft was implanted in 1 ulnar defect in each cat, with the contralateral ulnar defect serving as a nongrafted specimen. Six cats were treated by use of hyperbaric oxygen at 2 atmospheres absolute for 90 minutes once daily for 14 days, and 6 cats were not treated (control group). Bone labeling was performed, using fluorochrome markers. Cats were euthanatized 5 weeks after implanting, and barium sulfate was infused to evaluate vascularization of grafts. Ulnas were evaluated by use of radiography, microangiography, histologic examination, and histomorphometric examination. RESULTS: Radiographic scores did not differ between treatment groups. Microangiographic appearance of grafted defects was similar between groups, with all having adequate vascularization. Differences were not observed between treated and nontreated groups in the overall histologic appearance of decalcified samples of tissue in grafted defects. Mean distance between fluorescent labels was significantly greater in cats given HBOT than in nontreated cats. Median percentage of bone formation in grafted defects was significantly greater in cats given HBOT. CONCLUSIONS: Hyperbaric oxygen treatment increased the distance between fluorescent labels and percentage of bone formation when incorporating autogenous cancellous bone grafts in induced nonunion diaphyseal ulnar defects in cats, but HBOT did not affect revascularization, radiographic appearance, or qualitative histologic appearance of the grafts. 相似文献

Complications associated with femoral capital physeal (CP) fractures in 34 dogs were evaluated. Fractures were surgically repaired, using divergent K-wires or lag screws; radiographic follow-up was available for 21 CP fractures. In all cases, radiographic abnormalities such as degenerative joint disease and resorption of the femoral neck and/or head were seen. Changes were more severe when fracture occurred at an early age. For 4 of 21 dogs (20%), femoral head and neck excision was performed because of complications associated with CP fracture repair. Prognosis for femoral CP fractures is guarded, although affected dogs should be able to function as pets. 相似文献

Unilateral cryptorchidism and Sertoli cell tumor in the descended testis were provisionally diagnosed by use of ultrasonography in a 7-year-old Keeshond. The left testis was thought to have degenerated, but ultrasonography of the scrotum did not reveal evidence of testicular or epididymal tissue. The contralateral testis contained a hypoechoic mass believed to be a testicular tumor. Surgery and histopathologic findings confirmed the diagnosis. Ultrasonography of the scrotum and its contents should be considered for use in animals with suspected testicular neoplasia and/or degeneration. 相似文献

The life cycle of Paragonimus kellicotti was studied in dogs fed 25 or 50 metacercariae obtained from the hearts of naturally infected crayfish. Young flukes excysted in the intestines and appeared in the peritoneal cavity within 7–14 days after inoculation (DAI) and in the pleural cavity from 7 to 43 DAI. Immature flukes penetrated the pulmonary parenchyma between 7 and 10 DAI and became sexually mature between 28 and 35 DAI. Virtually all growth of the flukes occurred in the lungs. Eggs first appeared in feces 30 DAI. Pulmonary lesions were caused by the penetration and growth of flukes and the lesions were first detected by thoracic radiography 3 weeks after inoculation. Clinical signs were generally mild and consisted of an intermittent cough. Two dogs died suddenly of pneumothorax due to the rupture of cysts 32 and 35 DAI, respectively. 相似文献

A 9-year-old sexually intact male Boxer with a history of multiple episodes of syncope and various cardiac arrhythmias was determined radiographically to have a large mass in the heart-base region and was subsequently euthanatized upon worsening of clinical signs. Histologic and ultrastructural examination of tissue from the heart-base mass indicated that the tumor was most likely a chemodectoma derived from the aortic body (aortic body tumor, extra-adrenal paraganglioma). Macroscopic and/or microscopic evidence of metastasis of the tumor was seen in the lungs, myocardium, spleen, liver, kidneys, and dura mater over the cerebellum. 相似文献
