Conditions for the successful use of science     

Carter C 《Science (New York, N.Y.)》1983,219(4590):1295-1298

There is ground for concern that the British research and development effort, which is of considerable size, may not be well distributed. In some areas of intense scientific effort, commercial priorities tend to be forgotten. Too many of the units of the economic system are backward in understanding what science can offer and inefficient in using the opportunities which it provides. Evidence suggests that the successful use of science depends on the overall quality of management rather than specifically on its degree of scientific knowledge.  相似文献

Esophageal ectasia in a quarterhorse colt     

Barber SM  McLaughlin BG  Fretz PB 《The Canadian veterinary journal. La revue veterinaire canadienne》1983,24(2):46-49

A one month old Quarterhorse colt was presented after a week history of bilateral nasal discharge and respiratory difficulty. The cervical esophagus was greatly dilated, tortuous and filled with diluted milk. A nasogastric tube could not be passed beyond the base of the heart. An aspiration pneumonia was found at postmortem examination and the esophageal segment from the pharynx to the base of the heart was dilated, thin-walled, had degenerative muscular changes, and a reduction in size and number of ganglion cells of the myenteric plexus. Muscular hypertrophy of the terminal esophagus had reduced its lumen size. Some similarities and disparities of this condition to achalasia of man and megaesophagus of dogs are discussed.  相似文献   

Selenium levels of beef cattle in southeastern british columbia relative to supplementation and type of pasture     

Fenimore RL  Adams DS  Puls R 《The Canadian veterinary journal. La revue veterinaire canadienne》1983,24(2):41-45

Moderate to extremely low levels of selenium in hay were related to marginally deficient levels of selenium in sera from cattle in the Windermere Valley of southeastern British Columbia. Deficiency was most pronounced in cattle fed local hay during the winter or grazed on fertilized/irrigated pastures. Cattle on range had adequate levels of serum selenium. When sodium selenite was fed at 1.0 and 3.5 mg per head per day, serum selenium levels increased commensurate with the dose. Clinical observations indicated that a variety of clinical problems disappeared after injection or supplementation with selenium/vitamin E.  相似文献

Cervical intervertebral disc protrusion in two horses   总被引：2，自引：1，他引：1  

Foss RR  Genetzky RM  Riedesel EA  Graham C 《The Canadian veterinary journal. La revue veterinaire canadienne》1983,24(6):188-191

Two horses with ataxia of all four limbs were found to have cervical intervertebral disc protrusion. Severe pelvic limb ataxia, proprioceptive deficits and spasticity were present in both horses with similar but less severe signs in the thoracic limbs. Cerebrospinal fluid analysis was within normal limits. Metrizamide myelography allowed definitive diagnosis in one case when a compression of the spinal cord was demonstrated at the level of the second intervertebral space. In the second case, an intervertebral disc protrusion between cervical vertebrae 6 and 7 was found at necropsy. Fiber degeneration with poor myelin staining characterized the spinal cords histologically.  相似文献   

Exercise in electrocardiographic interpretation     

Allen DG  Downey RS 《The Canadian veterinary journal. La revue veterinaire canadienne》1983,24(6):199

The response of the heart to disease can be detected by assessing myocardial electrical activity. The electrocardiograph is a useful diagnostic tool which is widely available to the veterinary clinician. However, interpretation of the tracing often requires considerable experience.  相似文献
