NERVE DEGENERATION IN POLIOMYELITIS

Archives of Neurology & Psychiatry, 1932
For purposes of comparison with the degenerating fibers of nerves and roots from monkeys killed during the acute stage of poliomyelitis, it was deemed advisable to study by physiologic and histologic methods normal nerves severed from their cells of origin.

Chemical degeneration of intestinal nerves

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1990
In 15 dogs, cobalt chloride solutions were infused close intra-arterially to perfuse a short segment of the jejunum. In an additional four dogs, the jejunum was perfused with the aqueous vehicle (perfusion control). All animals were killed after 1 mo and tissue samples from cobalt-treated and from nonperfused intestine (tissue comparison control) were

OPTIC NERVE DEGENERATION IN ALZHEIMERʼS DISEASE

Journal of Neuropathology and Experimental Neurology, 1986
Alzheimer's disease is a dementing disorder of unknown cause in which there is degeneration of neuronal subpopulations in the central nervous system. In postmortem studies, we found widespread axonal degeneration in the optic nerves of 8 of 10 patients with Alzheimer's disease.

Retrograde Degeneration of the Cochlear Nerve

Acta Oto-Laryngologica, 1975
Retrograde degeneration of the cochlear neurons has been studied in different types and degrees of peripheral cochlear damage such as acoustic trauma, intoxication, heredodegenerative deafness and others. It starts only when the peripheral dendrites to the inner hair cells are irreversibly damaged.

Ischemic Degeneration of Nerve Fibers

Archives of Neurology, 1960
Direct evidence that nerve fiber degeneration may follow occlusion of groups of regional vasa nervorum, although provided by the experiments of Okada 17 (1905), Adams 1 (1943), Durward 11 (1948), and Roberts 19 (1948), has been scanty, and the conclusions to be drawn from the highly variable, but mainly negative, results of these experiments are ...

Degeneration behaviour of the cochlear nerve

Archiv f�r Klinische und Experimentelle Ohren- Nasen- und Kehlkopfheilkunde, 1971
On the basis of the degeneration behaviour two different types of cochlear afferent neurons can be distinguished. About 95% of all cochlear neurons are of the common type I with large myelinated spiral ganglion cells. They show complete retrograde degeneration after transsection of the cochlear nerve and they are exclusively connected to the inner hair

Peripheral Nerve Glycolysis in Wallerian Degeneration

Archives of Neurology, 1967
Although lLTHOUGH no completely satisfactory explanation for the changes occurring in the transected nerve has been established, nevertheless, changes in some enzymes associated with experimental wallerian degeneration have been reported. Most prominent among these are acetylcholinesterase, phosphatases, succinic dehydrogenase, and β-glucuronidase. 1-8

Traumatic myxomatous degeneration of a peripheral nerve

Hand, 1974
Abstract A twenty-one-year-old man presented with an unresolved radial palsy of five months' duration. Surgical exploration revealed a cystic ganglion-like swelling within the radial nerve in the midarm. Histological examination of this mass demonstrated myxomatous degeneration of the nerve.

Chlorhexidine-induced degeneration of adrenergic nerves

Acta Neuropathologica, 1984
Possible toxic effects of chlorhexidine (CHX) on the sympathetic adrenergic ground plexus were studied in whole mounts of albino rat irides using Falck-Hillarp fluorescence histochemistry. CHX dissolved in an isotone , buffered sodium-acetate solution or in 70% alcohol was injected into the anterior chamber of eye.

NERVE DEGENERATION IN POLIOMYELITIS

Archives of Neurology & Psychiatry, 1933
The special predilection of the virus of poliomyelitis for the large anterior horn cells of the spinal cord is a well established and generally accepted feature of this disease. The cytopathologic changes occurring in these cells have been reviewed frequently.
