Localized lesions of the central nervous system do occur in cattle. Those affecting the cranial nerves and focal lesions of the spinal cord are most easily recognized by careful neurologic examination. Once the lesion has been anatomically localized, likely etiologic causes can be pursued. Probably the most common cause of cranial nerve deficits in cattle is listeriosis. Important differential diagnoses include brain and pituitary abscesses and extensions of ear infections. Other possible causes include PEM, TEME, hypovitaminosis A, and several rare, sporadic causes. In young cattle, spinal trauma and vertebral body abscesses are the most common causes of progressive paresis resulting from spinal cord lesions. Congenital abnormalities must be considered in the differential diagnoses for very young calves. Non-neurologic conditions, including fractures of the limbs and especially nutritional muscular dystrophy, must be ruled out. In older cattle, compressive neoplasms, most notably lymphosarcoma, are primarily responsible for progressive paresis. Differential diagnosis should include other neurologic conditions such as delayed organophosphate neurotoxicity; early progressive diffuse neurologic diseases such as rabies, pseudorabies, and botulism; plant toxicities; and non-neurologic conditions resulting in recumbency, such as hypocalcemia and musculoskeletal trauma.

It is shown that E-hypovitaminosis-induced muscular dystrophy in rabbits is accompanied by a sharp decrease in the body mass, an increase in the urine creatine-index, a decrease in the vitamin E and ubiquinone contents in the liver and skeletal muscle tissues. In the myocardium mitochondria a decrease in the vitamin E content and an increase in the ubiquinone content are observed. The activity of NADH-cytochrome c-, NADH-ubiquinone- and succinate-ubiquinone-reductase also varies in mitochondria of the studied tissues. In myocardium organellas a direct dependence is found between the content of ubiquinone, NADH- and succinate-ubiquinone-reductase activity and an inverse one-between its content and the activity of the NADH-cytochrome c-reductase system. It is established that p-oxybenzoic acid as well as vitamin E prevents development of muscular dystrophy and causes changes analogous in direction in the activity of the ubiquinone-dependent enzymic systems of mitochondria. Ubiquinone-9 is less efficient in preventing the development of muscular dystrophy.
