Lead poisoning was diagnosed in four primates by the finding of toxic amounts of lead in tissues. Abnormalities in the brain and spinal cord were characterized by vascular lesions and demyelination. These findings suggest a new animal model for the study of demyelination and strengthen the supposition that lead may be a factor in some idiopathic demyelinating diseases.  相似文献

Transverse sections of the thorax of the Beagle were prepared, photographed, and compared with computerized tomographic scans and dissection specimens. Anatomical features were identified by these means with the aid of anatomical texts. A series of labeled photographs was produced to aid in the interpretation of computerized tomography and nuclear magnetic resonance scans.  相似文献
