Wow.
Researchers started experimenting on guinea pigs. They first isolated and compressed a segment of the rodent’s spinal cord. Subsequently, they applied the chemical and a fluorescent dye that could only enter the cells through damaged membranes. Scrutinizing the tissues under the microscope, the investigators noted that all the neurons in the spinal cord tissue remained unstained by the dye. Moreover, while measuring the guinea pigs’ brain response, they observed that the signals failed to reach the brain because of the damaged spinal cord. Thirty minutes after injecting the sugar mixed with sterile water into the bloodstream of the animals the researchers found that the damaged cells had been repaired.
The experts stated, “However, 30•min after injecting chitosan into the rodents, the signals miraculously returned to the animals’ brains.” Researchers theorize that the injected sugar migrates to the spinal cord injury where it plugs holes in the coating of the nerve cells.
Borgens added, “Science has moved in a new direction. Previously we have been looking at drugs which would potentially reduce damage. Now we are looking at complete repair.”
