When the toxin of Clostridium botulinum is administered to three (Mr.) nerve that tells the central nervous system the perception of the region of face, associate professor Yoshizo Matsuka of the Okayama University

When the toxin of Clostridium botulinum is administered to three (Mr.) nerve that tells the central nervous system the perception of the region of face, associate professor Yoshizo Matsuka of the Okayama University graduate school (implant regeneration prosthetics) et al. are the Rattus norvegicus var. albinus experiments and confirmation linguas as for there is a possibility of softening the prosopalgia.
As for this toxin, there is a benefit such as producible at a low price compared with morphine etc. , and practical use is expected as a new alternative of the soreness relaxation of the cancer.

Two professor Megumi Oguma of a large this graduate school (pathogenic bacterium study) used only the neurotoxin from the complex of a neurotoxin and a nontoxic protein in the botulinal toxin and the plutonium separation and purifying what were used.

Associate professor Matsuka et al. Rattus norvegicus var. albinus's bind) nerve with the silk thread, generate the prosopalgia artificially, and are ..tip (.. shots as for the toxin.
It was suppressed to about 1/2 compared with the mouse that did not inject the toxin, and the effect continued for about two weeks when it stimulated and the degree of pain was measured to the face with the provision.

In addition, about 1/3 of the Rattus norvegicus var. albinus that the amount of the neurotransmitter that told the soreness had not injected with the toxin when the trigeminal ganglion cell was examined.
