Abstract:
Objective To study the changes of endothelin-1(ET-1) and calcitonin gene-related peptide(CGRP) in plasma of cerebral vasospasm(CVS) after resection of skull base tumors and the effect of the two factors on cerebral vasospasm. Methods Totally 34 cases were divided into symptomatic cerebral vasospasm group,asymptomatic cerebral vasospasm group and nonvasospasm group after resection of skull base tumors.The blood specimens were obtained from the 34 patients on days 1,3,5,7 and 14 after the resection.The concentration of ET-1 and CGRP was detected by radioimmunoassay;meanwhile,transcranial doppler was recorded.Another 10 normal adult served as control group. Results ① Concentration of ET-1 in plasma elevated from the 1st day after resection of skull base tumors,reaching peak levels on day 5 to day 7,then decreased gradually and nearly recoverd on day 14.Concentration of CGRP in plasma decreased from day 3 after resection of skull base tumors,with the lowest concentration on day 7,then increased gradually and recoverd on day 14.② Concentration of ET-1 in plasma of the three groups was higher than that of normal adult group,while concentration of CGRP of the three groups was lower than that of normal adult group.③ Concentration of ET-1 in plasma in vasospasm groups was higher than that in nonvasospasm group(P
