ABSTRACT
Objective: To explore the effect of Plastrum Testudinis on the three subtypes of NOS (nNOS,iNOS,eNOS) expression in rats with focal cerebral ischemia. Methods:Rat model of focal cerebral ischemia was set up by inserting nylon thread into the internal carotid artery . The expressions of nNOS, iNOS and eNOS was detected by immunohistochemical method to observe the effects of Plastrum Testudinis. Results: Expressions of nNOS and iNOS in cerebral cortex and caudate-putamen of Plastrum Testudinis treatment group were significantly lower than those of model control group (P
ABSTRACT
Objective To investigate the effect of Plastrum Testudinis on neural stem cell after focal cerebral ischemia.Methods Rat models of focal cerebral ischemia were established by inserting nylon thread into the anterior cerebral artery.Immunohistochemical method was used to detect the expression of the neuroepithelial stem cell protein(Nestin),neurologic deficit and histological features were also observed.Results Plastrum Testudinis can decrease the neurologic dificit score and promote the expression of Nestin.Conclusion Plastrum Testudinis can alleviate the neurological symptoms and promote the proliferation of neural stem cell after focal cerebral ischemia.
