Russia of dispatch United States forced business company on September 4 ridge sanitation and scientific university (OHSU) the method that researcher adopts gene transplanting to stimulate blood capillary to grow in the lab, audition hair cell is bred successfully inside the cochlea of experimental rat, the audition that is destroyed to restore the mankind provided important and scientific basis. This study the breakthrough makes clear, future can find new method treat the mankind successfully to break acute hearing, relevant research is published in newest first phase as a result " natural " on the magazine. Medicine considers to make clear, because cell of inner ear hair is damaged,deaf is normally, cannot transmit voice question mark to give cerebrum be caused by. Hair cell is like dirt imperceptibly, be located in inside cochlea Ke Di implement part, distributinging on its 15 thousand arrive cell of 20 thousand hair, after hair cell forms albumen fasciculus, these change sound wave signal into electric pulse. Medical bound thinks all the time, hair cell death can appear break acute hearing. In be in tremendous noise the growth of the age, for a long time, perhaps encounter certainDiseaseCan cause hair cell occurrence breakdown or death, because this is brought about,break gradually acute hearing. And these protein fiber inside ear are very fragile, although just be damaged partly, audition also will possible permanent break acute hearing, the cell of inner ear hair that then researcher decides to choose and employ persons is versed in the method restores to be damaged. Does the assistant that studies otolaryngology of research center of audition of college of medicine of university of chief, OHSU teach John? The crucial gene that Dr. Bulaigende and colleague carry the protein Atoh1 that is in charge of a kind forming hair cell transplants to produce hair cell into experimental rat inner ear, embedded time is to be in a few weeks before hair cell fiber has not begun to form inside. Form when plumule after 4 days when, researcher considers carefully on the electron microscope to discover when hair cell, the hair cell of new generation inside experimental mouse system compares cells of those not embedded hair to contrast proteinly group mice increased one times. Sequel considers to make clear, protein Atoh1 stimulated Ke Di not only implement of exterior cell grow, also stimulated the growth of its interior cell. Also discover at the same time, in the hair that normally the environment leaves these new generation the cell can change sound wave signal into electric pulse signal. Concerned expert points out, this is a very important scientific research result, that is to say, resume damage hearing completely likely with artificial method. Just need to consider to be clear about further, the duplicate talent that needs how many protein Atoh1 restores injured hair cell, and how these protein embedded arrive inside person ear. Bulaigende says, one of methods of repair audition function are to use
