Abstract:
Objective To discuss the changes of the S100B protein concentration in serum and cerebral spinal fluid(CSF) after subarachnoid hemorrhage(SAH) in rabbit model and their significance.Methods Rabbit SAH model was induced by the cisterna magna puncture and injection two times of autogeneic blood into the cisterna magna.The animals were divided randomly into SAH group,saline group,puncture group and blank group.The serum and CSF were taken in blank group after 3 days' breeding.At 1 h,3 d,5 d,7 d and 10 d after the first infusion,the serum and CSF of the other groups were taken.ELISA method was used to detect S100B protein concentration in serum and CSF.The result data was analyzed by software SPSS13.0.Results S100B protein concentration in serum and CSF of SAH group was much higher than that in the other three groups(P=0).S100B protein concentration in serum ascended from 1 h after SAH,reached the peak at 3～5 d after SAH,and then descended slowly.S100B protein concentration in CSF ascended from 1 h after SAH,then slightly descended,ascended and reached the peak at 5～7 d after SAH,and then descended slowly.S100B protein concentration in serum and CSF of saline group was higher than that in puncture group and blank group from 1 h after model establishment(P
