目的:寻找快速、便捷有效的靶向中枢给药方法,为脑梗死治疗提供新的思路。方法线栓法制作大鼠大脑中动脉闭塞( Middle cerebral artery occlusion,MCAO)脑缺血再灌注模型,采用ELISA法测定经鼻( IN)和静脉( IV)注射CGRP后30 min时,各脑区的CGRP浓度,并观察IN和IV给予CGRP对局灶性脑梗死的治疗效果。结果 IN给药组脑部各区域、颈髓和脑脊液(Cerebro-sPinal fluid,CSF)中CGRP浓度较IV组显著增高(P<0.01),与IV组相比较,IN给药组梗死体积减小,脑血流量增加( P<0.01)。结论 CGRP经鼻靶向中枢给药可以避开血脑屏障阻碍,并对大鼠局灶性脑梗死有预防和保护作用。
目的:尋找快速、便捷有效的靶嚮中樞給藥方法,為腦梗死治療提供新的思路。方法線栓法製作大鼠大腦中動脈閉塞( Middle cerebral artery occlusion,MCAO)腦缺血再灌註模型,採用ELISA法測定經鼻( IN)和靜脈( IV)註射CGRP後30 min時,各腦區的CGRP濃度,併觀察IN和IV給予CGRP對跼竈性腦梗死的治療效果。結果 IN給藥組腦部各區域、頸髓和腦脊液(Cerebro-sPinal fluid,CSF)中CGRP濃度較IV組顯著增高(P<0.01),與IV組相比較,IN給藥組梗死體積減小,腦血流量增加( P<0.01)。結論 CGRP經鼻靶嚮中樞給藥可以避開血腦屏障阻礙,併對大鼠跼竈性腦梗死有預防和保護作用。

Objective To develoP a convenient and effective method for delivering CGRP to the central nervous system byPassing the blood-brain barrier( BBB),and to exPlore whether it had Preventive and Protective effects on cerebral in-farction in rats. Methods The MCAO model was made by nylon strand. CGRP concentration was measured IN and IV in-jection of CGRP after 30 min in different brain areas using enzyme-linked immunosorbent assay( ELISA),and exPlored the treatment IN and IV CGRP in rats with focal cerebral infarction. Results CGRP demonstrated a much higher delivery of IN than IV CGRP to the brain regions. Intranasal administration CGRP had significant Preventive and Protective effect to focal cerebral infarction which showed the brain infarction decreased and cerebral blood flow increased( P<0. 01 ). Conclusion CGRP intranasal administration targeting central administration can avoid the blood-brain barrier block,and had Preven-tive and Protective effects on the rats with focal cerebral infarction. Intranasal administration CGRP had definite Preventive and Protective effect to focal cerebral infarction in rats.
