Abstract:
Objective To explore the effect of sulbactam on brain tissue injury in rats with focal cerebral ischemia-reperfusion.
Methods Thirty male SD rats were selected and randomly divided into a sham group, a model group and a sulbactam group, with 10 rats in each group. The right cerebral ischemia-reperfusion model was prepared by thread embolism method. Thirty minutes after cerebral ischemia, the model group was intraperitoneally injected with 10 μL normal saline, the sulbactam group was intraperitoneally injected with 10 μL sulbactam, and the sham group was not given any intervention. Longa score was used to evaluate the neurological function of rats, Image-ProExpress imaging was used to analyze cerebral infarction volume, and immunohistochemical staining was used to detect serum glial glutamate transporter-1 (GLT-1) levels. Thirty days after surgery, Morris water maze was used to test learning and memory function, and the escape latency on days 1, 2, 3, 4, and 5 was compared.
Results The neurological function score and cerebral infarction volume in the sham group were 0, while those in the sulbactam group were significantly lower than those in the model group (P<0.05). The serum GLT-1 levels of the three groups were statistically significant (P<0.05), the serum GLT-1 levels of the sulbactam group and the model group were significantly higher than those of the sham group, while the sulbactam group was significantly lower than the model group (P<0.05). On the first day of test, the escape latency of the three groups was not statistically significant (P>0.05). On the 2nd to 5th day of testing, the escape latency of the three groups was statistically significant (P<0.05), the escape latency of the sulbactam group and the model group was significantly higher than that of the sham group (P<0.05), and the escape latency of the sulbactam group was significantly lower than that of the model group (P<0.05).
Conclusion Sulbactam can effectively improve nerve function, learning and memory function, reduce cerebral infarction volume and serum GLT-1 level in rats with focal cerebral ischemia-reperfusion.
