Laryngeal adenocarcinoma was diagnosed in a 5-year-old golden retriever dog with no history of respiratory or pharyngeal difficulties. Radiographically the basihyoid bone was destroyed by the neoplasm, and extensive soft tissue mineralization ventral to the larynx was also present. Complete surgical resection was not possible due to diffuse involvement of the tongue and larynx. Cobalt-60 teletherapy was used for treatment of the tumor. There was no clinical evidence of tumor regrowth at approximately 12 months post treatment. This is an unusual example of primary laryngeal neoplasia due to the absence of clinical respiratory abnormalities and the aggressive destruction of the basihyoid bone. 相似文献

Gastric myoelectric activity was measured in 10 dogs with spontaneous gastric dilatation-volvulus (GDV). Myoelectric activity was recorded with temporary, retrievable wire electrodes placed on the serosal surface of the stomach after derotation and tube gastrostomy. Gastric myoelectric activity was recorded for 1 hour daily, beginning with the day of surgery (less than 24 hours), 24, 48, 72, 96, 120, 144, and 168 hours after surgery. Recordings were also obtained for 1 hour daily after feeding, beginning 24 hours after surgery. Bradygastria was the predominate dysrhythmia immediately after surgery and at hour 24. The mean slow wave frequency was more than normal at hours 48 to 168 due to an increase in tachygastria and arrhythmias. The slow wave frequency significantly decreased after feeding at hours 120 and 144. The overall mean percentage of dysrhythmias was significantly decreased after feeding at hour 72 only. The mean percentage of spike activity ranged from 37.7 +/- 12.5 to 75.7 +/- 6.2 throughout the 8-day study period. Thus, gastric myoelectric activity was disrupted in these dogs with spontaneous GDV and subsequent tube gastrostomy. Feeding did not greatly diminish these dysrhythmias. 相似文献

Serum concentrations of cefepime (BMY-28142), a broad-spectrum cephalosporin, in dogs. 总被引：1，自引：0，他引：1
Serum concentrations of cefepime (BMY-28142) were determined for four dosing regimes, 10 mg/kg or 20 mg/kg, given as single subcutaneous (SC) or intramuscular injections (IM) to dogs. Serial serum samples were analyzed for the presence of cefepime by high-performance liquid chromatography. In experiment 1, the overall mean (+/- SEM) serum concentration (for a 12-hour period) after a dose of 20 mg/kg for SC and IM routes (4.9 +/- 0.74 micrograms/ml and 5.5 +/- 0.63 micrograms/ml, respectively) was twice that for the 10 mg/kg dose given either SC or IM (2.2 +/- 0.31 micrograms/ml and 2.8 +/- 0.47 micrograms/ml, respectively). There was no significant difference (p greater than 0.05) in mean serum concentrations for SC and IM routes of administration at the same dosage. In subsequent experiments, 5 doses of cefepime (20 mg/kg) were administered IM at 12-hour (experiment 2) or 24-hour (experiment 3) intervals. The mean (+/- SEM) peak serum concentration was 12.1 +/- 1.59 micrograms/ml, 2 hours after the 2nd injection in experiment 2. In experiment 3, the mean (+/- SEM) peak serum concentration was 10.9 +/- 1.34 micrograms/ml, 4 hours after the 1st injection. Mean trough concentrations in experiment 2 were greater than or equal to 0.5 microgram/ml and less than or equal to 0.5 in experiment 3. Multiple IM doses produced transient edema at the injection site and mild lameness in all dogs. Cefepime was highly active against single canine isolates of Staphylococcus intermedius, Pseudomonas aeruginosa and Escherichia coli, with minimum inhibitory concentrations of 0.125 microgram/ml, 1 microgram/ml and 0.3 microgram/ml, respectively. 相似文献

A novel, yet simple and inexpensive, technique is described for the safe passage of suture material for closure of patent ductus arteriosus in small animals. The risk of haemorrhage is reduced by minimising dissection with forceps and by preventing inadvertent grasping of perivascular connective tissue. 相似文献

Transilial pins and paired plastic spinous-process plates were used to repair fracture-luxations of the sixth lumbar vertebra in 6 dogs. All dogs had signs of lumbar pain and variable lower motor neuron deficits to the hindquarters (including hind limbs, tail, and pelvic region). Lumbar pain was decreased or resolved the day after surgery in all dogs, and 3 dogs were able to walk without assistance. One dog initially deteriorated neurologically after surgery and 2 dogs with multiple concurrent orthopedic injuries had no improvement in neurologic function and remained nonambulatory. Pin migration associated with improper bending of the transilial pins and requiring early implant removal was the most common postoperative complication. Four dogs had no neurologic abnormalities 1 to 3 months after surgery. One dog had a resolving unilateral sciatic nerve deficit 9 months after surgery, and another dog was euthanatized 3 months after surgery because of continued paraparesis and urinary and fecal incontinence. These 6 cases illustrate the efficacy of plastic spinous-process plates in combination with transilial pins for the repair of fracture-luxation of the sixth lumbar vertebra. 相似文献
