1. Lacking a myelin sheath. Used of a nerve fiber.

2. At the same time following surgery, the myelin sheath thickness and the cross section area of myelinated nerves in the experimental groups were significantly greater than that in the controls.

3. To destroy or remove the myelin sheath of a nerve fiber, as through disease.

4. Most neurons are insulated by a myelin sheath formed by cells ( Schwann cells ) surrounding the axons.

5. Conclusion: Myelinated nerve fiber positive area and myelin sheath area are the more sensitive markers of the course and therapeutic outcome of DPN.

6. This myelin sheath is, basically, electrical tape, which is one reason that myelin, along with its associated cells, was classified as glia (Greek for "glue").

7. The neuropathies in myelin sheath and Nissl body were markedly attenuated in group K.

8. Conduct the pathological observation on area of myelin sheath, extramedullary fiber and the cross section of myelin sheath of sciatic nerves.

9. Myelin sheath of sciatic nerve and Nissl bodies in neurons were demonstrated with staining of solechrome cyanin and buffered methylene blue, respectively.

10. Brain biopsy revealed severe damage to the myelin sheath. Question is, why?

10. try its best to gather and make good sentences.

11. It forms the myelin sheath of nerve fibres which facilitates the transmission of nerve impulse and insulates against cross-talks.

12. And wide gaps appeared between axon and myelin sheath, and between layers of myelin shea.

13. Result:The regenerated nerves of decimeter wave sides had more medullated fibers, larger mean axons diameters and thicker myelin sheath than those of control sides.

14. Results Bad protein was positively expressed in the normal optic nerve myelin sheath and residual myelin portions of optic nerve tissues from traumatic atrophic eyes.

15. Conclusions The myelin was progressive damage in morphine dependent rats, and histomorphologic changes of myelin sheath in VTA might contribute to the development of morphine dependence.

16. Number and diameter of mean nerve fibre in unit area of transverse plane, diameter of axon and depth of myelin sheath were calculated.

17. CONCLUSION:The degree of denervation is a marker for rehabilitative diagnosis of FP, and is related to the destruction degree of myelin sheath and axon.

18. Multiple sclerosis occurs when the body launches an immune system attack against itself, destroying the myelin sheath and leading to immobility among sufferers.

19. Results: After 2 and 4 weeks in the experimental group, a large amount of myelinated nerve fibers, Schwann cells were observed with light microscopy, and thickness of myelin sheath increased.

20. Filamentous neurofibrils and mitochondria were observed in axons. Axons were enveloped by myelin sheath, presented alternately dark and bright lamellae concentric configuration.

21. RESULTS: After trauma, some neurons displayed histopathologic changes of necrosis and apoptosis, axon myelin sheath internalization and disconnection.

22. The electron microscope was used to study the histomorphologic changes of myelin sheath in VTA.

23. "Because there is no myelin damage at birth, we assumed prions are needed to maintain the quality of the myelin sheath, which diminishes throughout life, " says Aguzzi.
