Abstract： Objective To observe the clinical effect of Ozagrel sodium with ultrasonic therapy in patients with acute cerebral infarction (ACI). Methods Eighty-three ACI patients were randomly divided into 2 groups: ultra-sortie therapy group(n=42) received Ozagrel sodium and ultrasonic therapy, whereas control group(n = 41) only ac-ecpted the Ozagrel sodium for injection. Both two groups were under conventional treatment. The level of laboratory in-dex and the neurological impairment were detected before and after treatment. And the clinical effect were detected in the end of the treatment. Results The neurological impairment and the clinical effect defected after therapy in both groups, had statistical difference(P < 0. 05), especially in the ultrasonic therapy group. Conclusion Ozagrel sodium with ultrasonic therapy in patients with ACI could promote recovery of the neurological function, thus increase clinical effect.
