摘要

Tendency to utilize Ephedra contain product are increasing due to its favorable properties such asenergetic, fat burning, decongestant etc. Present of cardiovascular agonism and adrenergic compound andlack of systematic research on this issue, we conduct this study to determine the Ephedra major Host.The present work aimed to study the effect of hydroethanolic extract of Ephedra major plant on vascular systemand its mechanism of action. Isolated aorta from 48 male Wistar rats (Body weight 220±30 g) were tested inorgan bath. Rats were anesthetized and aorta isolated and placed in Krebs-Ringer bicarbonate solutioncontinuously bubbled with 95% O2 and %5 CO2Carbogene then cut into ring segment 4mm in width which thenmounted in organ bath and contractive response recorded in 8 groups. Statistical compression made by studentT test and ANOVA (SPSS Ver.19). A P value of =0.05 was considered as statically significant. Half MaximalEffective concentration calculated by Lab Chart Ver.7 software. The result were shown E. major extract haveconstriction effect on rat aorta.The Contractile mechanism, wasn't only through agonistic adrenergicmechanism of aorta induced by extract is releasing internal calcium sources mediated by metabotropic G protein.This constriction effects is due to a adrenergic agonistic mechanism accompanied with other possiblemechanisms including depolarizing the calcium channels or by mediating the release of vasoconstrictive agentand or inhibition the release of endothelium relaxant.
