The new method of transferring medicine to the cochlea helps to restore hearing

The new method of giving medicine to the cochlea helps restore damaged ear hair, regenerate synapses to treat hearing loss.

According to research results published in Bioconjugate Chemistry, scientists for a long time have tried to find ways to restore hearing to people with hearing impairment.

Recently, experts at the University of Southern California and Harvard University, USA, have realized how to repair damaged cells in the inner ear. This finding was done in laboratory experiments with animal tissue.

It is known that hair cells in the cochlea are extremely slender, gradually deteriorating over time, which can lead to hearing loss. The main problem is that any soluble drug used to restore hair cells is washed away by the liquid in the ear. However, researchers have realized how to solve this problem. The researchers created a new way to bring the drug to the cochlea, an inner ear structure that receives sound in the form of vibrations.

Thanks to a new drug delivery method, synapses have been recreated, leading to the recovery of hair cells and neurons. Scientists used a combination of 7,8-Dihydroxyflavone (7,8-DHF) , simulating an important protein for body growth and bisphosphonate (a drug that reduces osteoporosis) that sticks to the bone. Experts hope that the new method will help deaf people.

Professor McKenna and colleagues believe that they will soon conduct tests on the hearing impaired. Meanwhile, an Italian study found that hearing problems can be a warning sign of dementia in the elderly.
