The histopathological changes of the central nervous system and clinical disease of rats infected with two related BDV variants, CRP3 (rat-adapted variant) or CRNP5 (mouse-adapted variant) in Fischer 344 rats were investigated for 20 days. Infected rat pups were scored for incidence and severity of BD (the severity of disease in rats ranked on a scale of 0 to 3+) and examined histopathologically. In addition, we selected the protocol design and testing procedures for assessing behavior of BDV infected rat neonates. Compared to newborn rats inoculated with CRP3, newborn rats inoculated with CRNP5 had more severe histopathological changes in the central nervous system, mainly in the hippocampus. There was no evidence of encephalitis in either CRP3 or CNRP5 infection. In CRNP5 infection, there were severe degeneration of the pyramidal neurons of the hippocampus and extensive hippocampal gliosis. On the contrary, CRP3-inoculated newborn rats had little histopathological changes in the hippocampus by day 20 p. i.. As for the severity of BD, all neonatal rats inoculated with CRNP5 were scored 1+ by day 12 p. i.. On the day 16 p. i., six out of eight rats were scored 2+. By day 20 p. i., all rats were ranked 2+ or 3+, and one infected rat died. On the other hand, CRP3-inoculated newborn rats showed no apparent neurological signs by day 20 p. i.. In addition, we chose a) body lighting, b) negative geotropism, c) grasping response, d) fore limb and hind limb placing and e) bar holding test for the behavioral tests by postnatal days (PND) 20. From rats at PND25-28 onwards, beam walking (bar crossing) tests and open field tests were selected for assessment of the abnormal behavior., P(論文), 特集, application/pdf, FEATURE ARTICLES}, pages = {196--198}, title = {ボルナ病ウイルス感染動物を用いたヒト内因性精神疾患モデル動物の作出}, volume = {11/12}, year = {2006}, yomi = {マダラメ, ヒロオ and ニシノ, ヨシイ and イノウエ, マキ} }
