ABSTRACT
Objective:
To study the protective e ects and dosage-e ect relationship of Naomaitong on focal cerebral ischemia reperfusion in aged rats.Methods:
Focal cerebral ischemia model ( ischemia 3h and I/R12d)was duplicated with MCAO.The changes of the nervous dysfunction score ,the water content of cerebral constitution and the expression of TNF-?,VCAM-1,ICAM-1and its mRNA were observed.Results:
The nervous dysfunction score ,the water content of cerebral constitution, the expression of TNF-?,VCAM-1,ICAM-1and its mRNA in aged model group were higher than those of the sham-operated group;but all of these were decreased in three Naomaitong groups and Nimodipine group compared with that of aged model group;the nervous dysfunction score and the expression of VCAM-1,ICAM-1 mRNA in Naomaitong group(0.9g?kg-1) were lighter than that of the Nimodipine group;the nervous dysfunction score,the water content of cerebral constitution, the expression of TNF-?,VCAM-1,ICAM-1and its mRNA in Naomaitong group(0.9g.g-1.d-1) were higher than that of Naomaitong group(0.45g?kg-1?d-1).Conclusion:
Naomaitong could protect brain cell from damage after focal cerebral ischemia reperfusion injury by inhibiting the expression of TNF-?,VCAM-1,ICAM-1, with the middle dose of Naomaitong being more e ective.
