| Research Abstract |
For the study of eradication herpes simplex virus (HSV) persistence in the ganglion, A new rat model was established using the trigeminal ganglion and mental nerve. After intraneural injection of 2-3 micron of F strain of HSV, persistent infection was established in more than 80% of rats where viral DNA was detactable by in situ hybridization with biotinilated cDNA up to 502 after virus inoculation although no viral antigens were detectable 5 day after virus inoculation. A single injection of doxorubicin into the mental nerve reduced the incidence of virus isolation from cultured ganglion tissue from 31/37 (control) to 3/37. Therefore, retrograde axoplasmic transport of appropriate drugs can be used for the treatment of persistent virus infection in the ganglionic cells. Potential use of retrograde axoplasmic flow for acute infection of the CNS after neural spread of virus was explored in experimental rabies in rats.
