Propranolol alleviated postischemic brain inflammation. Rats receiving a normal saline vehicle or a propranolol (2 mg/kg) intraperitoneal injection were subjected to permanent cerebral ischemia for 24 h. Proteins were extracted from the contralateral and ipsilateral cortical tissues and subjected to Western blot (A) with the indicated antibodies or ELISA for the measurement of TNF-α (B). * p < 0.05 vs. the contralateral tissues of the vehicle group and # p < 0.05 vs. the ipsilateral tissues of the vehicle group, n = 6.
