In 2004 the dog became only the fifth mammal to have its entire genome fully sequenced. The canine genome was sequenced in the hope that it would help scientists understand the complex evolutionary mechanisms that shape genes and genomes and provide a powerful tool for identifying genetic factors that contribute to human health and disease. It is expected that over the coming years the genome of man's best friend will help in the understanding of the genetic cause of many inherited diseases that humans and dogs have in common. Not only of obvious benefit to humans, these studies will enable the development of DNA diagnostic tests that breeders can use to identify which of their dogs carry mutations that put them at risk of developing particular conditions and thus, over time, eliminate those diseases from the breed.  相似文献

A five-year-old, neutered male, Bernese Mountain Dog was referred because of a two-week history of hematuria and a one-week history of polydipsia and polyuria. Palpation of the dorsomedial mesogastrium revealed a mass on the left side, which was seen via radiography and ultrasonography to be attached to the left kidney. The left kidney and the attached mass were excised surgically, and the dog had an uneventful recovery. Histological examination of the mass revealed a dense proliferation of non-polymorphic spindle cells, which stained positive for smooth muscle actin via immunohistochemistry. Leiomyoma of the kidney was diagnosed. Postoperatively, there was mild azotaemia, which did not affect the general condition of the dog and was still present 15 months after surgery. Leiomyoma of the kidney is a benign tumor, and hematuria may be the only clinical sign.  相似文献

It should be emphasized that the primary function of the computer is information-handling and communication. It remembers who and when and why, organizes the information, and then communicates by reminders, letters, labels, word processing, and statements. The computer becomes a faithful employee, not altogether immune from physical illness but generally ready to work at the flip of a switch. Best of all, the computer never asks for overtime or a percentage of the profits.  相似文献

A severely comminuted fracture of the distal tibia, in a rabbit, was successfully treated by the application of Kirschner-Ehmer external fixator. The principles used in applying the apparatus are outlined, indicating its suitability of use in a variety of situations.  相似文献

Objective: To report open reduction and joint stabilization using a prosthetic capsule technique for treatment of a craniodorsal coxofemoral luxation in a lightweight pony. Study Design: Clinical report. Animals: Pony stallion (8 years old, 113 kg). Methods: A craniodorsal approach to the coxofemoral joint was performed under general anesthesia. After open reduction, a prosthetic capsule technique was used. Four 3.5 mm self‐tapping cortical anchor screws were implanted: 2 screws were inserted above the cranial aspect of the dorsal acetabular rim, and 2 screws were inserted into the femoral neck. Subsequently, a #5 USP ultra‐high molecular weight polyethylene suture was placed through these anchor screws in figure‐8 fashion to serve as a prosthetic capsule. Routine closure and a medial patellar desmotomy completed the surgical procedure. Postoperatively, the pony was cross tied for 4 weeks to prevent it from lying down. Results: Neither short‐term nor long‐term complications occurred and the pony was sound at the follow‐up examination performed 15 months postoperatively. Conclusions: A prosthetic capsule technique can be used successfully to stabilize the coxofemoral joint after open reduction of a craniodorsal luxation in a lightweight pony.  相似文献

A 14-year-old quarter horse mare had a 2-year history of infertility and the presence of a mass in the right uterine horn. Prior to surgery, the mass was determined to be invasive by using ultrasonography and hysteroscopy. A partial ovariohysterectomy was performed. The mass was diagnosed histologically as a uterine leiomyoma.  相似文献

Objective— To report repair of a right proximal tibial Salter-Harris type II fracture in a foal with a hybrid external fixator (HEF).
Study Design— Case report.
Animals— A 5-month-old male foal.
Methods— After open surgical reduction, an HEF built with wires, 2 half-rings, 3 half-threaded connecting rods, and Schanz pins was used to stabilize the fracture.
Results— Immediately after surgery, the foal had relatively good weight bearing. The HEF was removed at 60 days after radiographic confirmation of healing.
Conclusions— HEF can be used to stabilize a proximal tibial Salter-Harris type II fracture in a 5-month-old foal.
Clinical Relevance— HEF should be considered as another option for repair of proximal tibial Salter-Harris type II fractures in foals.  相似文献
