          <datacite:description descriptionType="Abstract">Dopamine(DA)の前駆物質L-3,4-dihydroxyphenylalanine(L-DOPA)
の神経伝達物質遊離機構に対する機能解明を目的に,in vivo microdialysisを用いてDA,serotonin (5-HT),acetylcholine(ACh)遊離に対する,細胞外DOPA濃度依存性効果を検討した.同時にmaximal electroshock seizure(MES)を用いたけい
れん閾値に対するL-DOPAの効果も検討した.細胞外DOPA濃度が100nM以下では濃度依存性にDA,5-HT,ACh遊離を亢進したが,100nM以上では逆にDA,5-HT,ACh遊離を抑制した.同様にDA,5-HT,ACh遊離亢進作用を有する100nM以下の細胞外DOPA濃度ではMESを軽度抑制し,100nM以上ではMESを亢進した.以上の結果は,L-DOPAの神経伝達物質あるいは神経修飾物質様作用の存在を示唆するものである.</datacite:description>
