RAPID AXOPLASMIC TRANSPORT IN DYSTROPHIC MICE

Journal of Neurochemistry, 1977
Abstract— Rapid axoplasmic transport was studied in dystrophic mice of the 129/ReJ‐dy strain. Proteins transported in vivo through α‐motoneurons of the sciatic nerve were labeled by injections of [3H] or [35S] amino acids into the ventral horn of the lumbar spinal cord.

Low temperature slowing and cold-block of fast axoplasmic transport in mammalian nerves in vitro.

Journal of Neurobiology, 1975
1) Fast axoplasmic transport in mammalian nerve in vitro was studied using an isotope labeling technique. The rate of outflow in cat sciatic nerve fibers of 410 mm/day in vitro was reduced at temperatures below 38 degrees C with a Q10 of 2.0 in the range

Axoplasmic transport with velocities induced by pargyline

Journal of Neuroscience Research, 1980
AbstractThe axoplasmic transport of proteins in spinal motor neurons is altered by pargyline, a drug that causes increased release of monoamines. Two new peaks of transported protein were detected in the sciatic nerves of rats treated with pargyline (75 mg/kg/day ip for three days).

Axoplasmic transport in ocular hypotony and papilledema in the monkey.

A M A Archives of Ophthalmology, 1977
Orthograde and retrograde axoplasmic transport were studied in optic nerve heads of seven hypotensive Macaca fascicularis eyes. Orthograde transport was studied by radioautography after intravitreal radioisotope injections.

Anoxic block and recovery of axoplasmic transport and electrical excitability of nerve.

Journal of Neurobiology, 1978
Axoplasmic transport of cat sciatic nerves was studied in vitro in a chamber in which maximal alpha action potentials could also be elicited. After initiation of N2 anoxia, electrical responses fell to zero at an average time of 22 min. A shorter time to

Microtubule and neurofilament densities in amphibian spinal root nerve fibers: relationship to axoplasmic transport.

Canadian Journal of Physiology and Pharmacology, 1973
Dark-field microscopy of living myelinated nerve fibers from the spinal roots of Xenopus laevis revealed many spherical organelles moving in the axoplasm of fibers from the ventral roots and in fibers just distal to the dorsal root ganglion.

Optic nerve hydropic axonal degeneration and blocked retrograde axoplasmic transport: histopathologic features in human high-pressure secondary glaucoma.

A M A Archives of Ophthalmology, 2007
OBJECTIVE To describe histopathologic features of anterior optic nerves of 12 eyes enucleated for sustained high ocular pressure from iris-ciliary body melanomas in 10 and choroidal melanomas with chronic angle closure in 2.

Effect of vinpocetine on retrograde axoplasmic transport

Annals of Anatomy - Anatomischer Anzeiger, 2007
Vinpocetine, a derivate of vincamine, is widely used in the clinical pharmacotherapy of cerebral circulatory diseases. Herewith we report on a novel effect of vinpocetine: inhibition of retrograde axoplasmic transport of nerve growth factor (NGF) in the peripheral nerve.

The role of microtubules in axoplasmic transport in vivo

Brain Research, 1986
To verify whether microtubules are involved in the mechanism of axoplasmic transport in vivo, [3H]leucine was injected into ventral horns of rats, and 3 h later Ca2+ or other drugs injected into sciatic nerves. The injection of 50-200 mM Ca2+, raising intra-axoplasmic Ca2+ levels, blocked transport above the intraneural injecting site and decreased ...

Studies on the mechanism of axoplasmic transport in the crayfish cord.

Journal of Neurobiology, 1970
Following the injection of 3H-leucine into a crayfish ganglion, tritiumlabeled proteins were detected remaining in the ganglion and moving at a slow linear rate caudad along the nerve cord. The rate of movement increased linearly with temperature between
