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

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   

A strategy for control of bovine leukemia virus infection: test and corrective management   总被引：2，自引：2，他引：0       下载免费PDF全文

Test and corrective management was applied in one dairy herd (130 milking cows) to control bovine leukemia virus infection. It consisted of: raising uninfected calves in order to establish a pool of uninfected replacement heifers, preventing transmission of bovine leukemia virus through transfer of blood from animal to animal and closing the herd. Regular herd testing was combined with selected changes in herd management. These procedures have been followed since January 1979. Prevalence of antibodies (as determined by gel-immunodiffusion) has declined markedly since the program was implemented.  相似文献   

The duration of immunity to an inactivated adjuvanted canine parvovirus vaccine. A 52 and 64 week postvaccination challenge study   总被引：1，自引：1，他引：0       下载免费PDF全文

Dogs were successfully isolated for a period of either 52 or 64 weeks following vaccination with an inactivated, adjuvanted canine parvovirus-2 vaccine. Antibody persisted in all ten vaccinated dogs, although in one case by 52 weeks postvaccination only virus neutralizing antibody, and not hemagglutination-inhibiting antibody, could be detected. Sentinel unvaccinated dogs housed alongside the vaccinated dogs throughout the study remained free of canine parvovirus-2 antibody until challenged. Upon oral challenge with canine parvovirus-2 infected material all unvaccinated dogs developed one or more signs of canine parvovirus-2 disease, shed virus and developed antibody. None of the vaccinated dogs became overtly sick. Of the five vaccinated dogs challenged 52 weeks after vaccination, three shed virus and one showed a significant rise in antibody. At 64 weeks after vaccination only one of the five challenged dogs shed virus and showed a boost in antibody titer.  相似文献
