摘要

Abstract

正

Objective: To study the correlation between aquaporin-4 （AQP4） expression and diffusion-weighted ima-ging （DWI） in the process of ischemic brain edema for the molecular biologic mechanism of DWI. Methods: A total of34 Wistar rats were divided into 8 groups randomly: Non-operated group （n=4）

sham-operated group （n=6）

andoperated group

receiving right midddle cerebral artery occlusion （MCAO） for 15 and 30 min

and 1

6 and 24 h re-spectively （6 subgroups

n=4）. All groups were imaged with DWI and T

WI. The apparent diffusion coefficient（ADC）

relevant density （rd） and relevant area （rs） of hyperintensity of the lesions on DWI and T

WI were meas-ured. Relevant ADC （rADC）

relevant area of immunohistochemical staining for AQP4 （rS）

optical density of AQP4hybridization （α） were calculated. After that the animals were sacrificed and perfused at different time intervals

cor-relations between DWI

ADC

and AQP4 expression （rS

α） in ischemic tissue was made. Results: There was a sig-nificant correlat
