ABSTRACT
Objective To observe the effects of Xifeng Tongnao capsules on the content of TNF-α and IL-1β in brain tissue of rats with focal cerebral ischemia-reperfusion injury. Methods A total of 120 adult SD rats were randomized into 6 groups Xifeng Tongnao low-, middle- and high-dose groups, model control group, Buchang Naoxintong group and sham-operated group.Buchang Naoxintong group were treated with Buchang Naoxintong capsules at 0.864 g??kg-1.Xifeng Tongnao high-, middle-and low-dose groups were treated with 3.456, 1.728, and 0.864 g??kg-1 Xifeng Tongnao capsules, respectively;sham-operated group and model control group were treated with equal volume of purified water. Medications were administered intragastrically once daily for 7 days. The acute transient focal cerebral ischemia-reperfusion model was established by middle cerebral artery occlusion ( MCAO) 1 h after the final dose, and rats in the sham-operated group only received anesthesia and stripping without occlusion.All rats were sacrificed after reperfusion for 24 h, and expression levels of TNF-α and IL-1β in the brain tissue were detected by ELISA. Results TNF-αcontent in Xifeng Tongnao capsutes low-, middle-and high-dose groups were (35.34±8.95), (33.75±6.92), and (40.95±5.39) ng??L-1, respectively.IL-1β content were (1.44±0.47), (1.45± 0.23), and (1.61±0.33) ng??L-1 in low-, middle- and high-dose groups, respectively.TNF-α and IL-1β were (38.96±9.84) and (1.56±0.31) ng??L-1, respectively in Buchang Naoxintong group, (52.74±6.76) and (2.79±0.45) ng??L-1in the model control group, and (32.54±4.00) and (1.32±0.22) ng??L-1 in sham-operated group.TNF-αand IL-1βcontent were significantly higher in Buchang Naoxintong group than in sham-operated group ( P<0. 05 ) . TNF-α and IL-1β content were significantly decreased in Xifeng Tongnao high-, middle- and low-dose groups (all P<0.05). Conclusion Xifeng Tongnao capsules can protect brain tissue by supressing TNF-α and IL-1β and alleviating inflammatory injury from ischemia.
