Abstract:: |
Objective To evaluate the different detection methods of blood brain barrier(BBB) disruption, and to explore the protection effect of basic fibroblast growth factor(bFGF) on the BBB disruption. Methods 60 rats were classified into radiation group, bFGF intravenous injection group and contol group. The water content of brain was measured by wet-dry weight formula and Evans blue(EB) concentration was detected after intravenous injection(3 mg/kg) after 2,7 and 30 days post irradiation in each group. The data were collected and analysed to evaluate the degree of BBB disruption. Results Both of EB concentration and water content in brain increased after irradiation, which were lower in bFGF injection group than those in radiation group (P<0.05). Statistic difference (P<0.05) was found at different days following exposure for EB concentration but not for water content in brain. Conclusions It's more effective of EB concentration to represent the BBB disruption than of water content. Intravenous injection of bFGF may have some protective effects on BBB disruption induced by radiation. |
