Multi-modality MRI Study on Effect to Collateral Circulation and Blood Perfusion of Acute Cerebral Infarction by Human Urinary Kallidinogenase

• Status: Completed
• Trial end date: 2014-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Human urinary kallidinogenase can promote the establishment of collateral circulation in the ischemic penumbra due to the stenosis or occlusion of middle cerebral artery and then increase the perfusion.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: XuanwuH 2
• Treatments: Kallikreins
