Regeneration of Axis Cylinders in Vitro
نویسنده
چکیده
It has been shown for the first time that nerve fibers grow out from pieces of cerebellum of young cats and guinea pigs, when cultivated in coagulated plasma. The same phenomenon has been observed in cultures of spinal ganglia. The nerve fibers do not anastomose and they extend into the plasma unaccompanied by structures of any kind.

Studies of the Degeneration and Regeneration of Axis Cylinders in Vitro
1. The brains of chick embryos, of cats six weeks old, of rabbits two months old, and of dogs three weeks old, when cultivated in vitro, develop long filaments which, according to their growth and their anatomical and tinctorial characters, must be considered as true axis cylinders. 2. Similar structures develop from spinal ganglia of rabbits seven months old, and from the spinal cord of cats s...
متن کاملA Computational Approach to the Flow of Walter’s Liquid B′ through Annulus of Coaxial Porous Circular Cylinders for High Suction Parameter (RESEARCH NOTE)
The present investigation studies the behavior of steady flow of visco-elastic liquid between two porous coaxial circular cylinders, where both the cylinders are rotating with different uniform angular velocities about the common axis. In addition, the inner cylinder has uniform velocity along the axis and the visco-elastic fluid, which is a Walters liquid B′, is allowed to flow in the annulus....

1. The Wallerian degeneration occurring in peripheral nerves by incubation in Ringer solution and serum does not occur in plasma. 2. Peripheral nerves incubated in plasma give rise to no growth. The same is true of peripheral nerves in a Wallerian degeneration up to the 4th day. 3. Peripheral nerves in Wallerian degeneration from the 5th day give rise to a growth of the syncytium of Schwann. In...
متن کاملThe Peripheral Theory of Nerve Regeneration with Special Reference to Peripheral Neuritis
nerve fibres growing downwards into the peripheral segment, either as (i) the result of the original nerve fibres themselves growing downwards, or (2) the result of the parent axiscylinders dividing into a number of young axis-cylinders, probably, it was thought, at the first node of Ranvier above the part of the nerve fibre damaged by the lesion (Strcebe). In the latter case the young axis-cyl...
متن کاملIndirect in vitro regeneration of lentil (Lens culinaris Medik.)
Establishment of an efficient and reproducible regeneration protocol is one of the basic prerequisites for genetic transformation of any crop plant. In vitro culture of lentil has proven to be difficult. In spite of a number of reports on the regeneration of this plant, very few satisfying and reproducible protocol has yet been reported. This study carried out for investigation of diff...
