To explore therapeutic effects of Erigeron breviscapus and mechanisms of cerebral vascular spasm(CVS) after exper2 imental Subarachnoid hemorrhage(SAH) . METHODS
Forty - eight SD rats were divided randomly into four groups : control group ,cerebral vasospasm group , Erigeron breviscapus group and Nimotip group . Experimental SAH in SD rats was made by injecting blood for two times. Basi2 lar artery diameter changes were monitored by stereotype microscopy. The levels of ET - 1 in plasm and NO in serum were measured by ra2 dioimmunoassay ,enzymology ,respectively at different times. RESUL TS
Compared with cerebral vasospasms group ,basilar artery diameters in Erigeron breviscapus group dilated significently( P < 0. 01) . The levels of ET - 1 in plasma were increased ,yet NO were decreased in cerebral vasospasm group compared with control group ( P < 0. 01) . In Erigeron breviscapus group ,the levels of ET - 1 were decreased and NO in2 creased compared with cerebral vasospasm( P < 0. 01) . CONCL USION
Eigeron breviscapus can inhibit increase of ET - 1 and decrease of NO to prevent and treat CVS following SAH.
