Metabolism of peripheral nerve myelin in experimental diabetes.
Previous in vitro studies of the metabolism of the peripheral nerve have been based on incorporation of radioactive precursor into components isolated from whole nerve. In this study we have determined incorporation secifically into myelin components of peripheral nerve by isolating myelin after incubating whole nerves with lipid or protein precursors and by determining the specific activity of...
متن کاملIncorporation of glycoproteins into peripheral nerve myelin
Peripheral nerve myelin contains a dominant low molecular weight glycoprotein called Po. To study the metabolism of this glycoprotein, tritiated fucose was injected into the peripheral nerves of adult mice and developing rats, and the temporal distribution of label was examined by autoradiography and gel electrophoresis. Mice and rat pups, injected with fucose, were sacrificed from 1 h to 98 da...
متن کاملExperimental myelin intrusion in the nerve head.
On the assumption that myelin intrusion into the papilla and peripapillary region might occur with traumatic lesions of the optic nerve, a study was made of the clinical and histopathologic changes that might be expected. Nine monkey eyes were subjected to hemostat compression of the nerve close to the globe and studied over variable periods up to 28 days. Myelin was demonstrable ophthalmoscopi...
متن کاملIncorporation of newly formed lecithin into peripheral nerve myelin
Radioactive choline was used to study the metabolism and movement of choline-containing phospholipids in peripheral nerve myelin of adult mice. Incorporation at various times after intraperitoneal injection was measured in serial segments of sciatic nerve as well as in myelin isolated from those segments. At no time (1 h to 35 days) could a proximal-distal difference in the extent of labeling b...
متن کاملRadioautographic Studies of Choline Incorporation into Peripheral Nerve Myelin
This radioautographic study was designed to localize the cytological sites involved in the incorporation of a lipid precursor into the myelin and the myelin-related cell of the peripheral nervous system. Both myelinating and fully myelinated cultures of rat dorsal root ganglia were exposed to a 30-min pulse of tritiated choline and either fixed immediately or allowed 6 or 48 hr of chase incubat...
