Abstract:
OBJECTIVE:To study the effects of salvianolate on the expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9(MMP-9)in lung tissue of mice with lung cancer. METHODS:C57BL/6 mice were randomly divid-ed into model group (normal saline),positive control group (cyclophosphamide 50 mg/kg) and salvianolate low-dose,medi-um-dose and high-dose groups(20,40,80 g/kg)with 10 mice in each group. They were ig 1 000 mg/kg urethane,twice a day, for consecutive 4 weeks to establish lung cancer model. After modeling,they were given relevant medicine intragastrically once a day for consecutive 14 d. Mice behaviors,symptoms,body weight,tumor inhibition rate,spleen index,thymus index,and the ex-pressions of VEGF and MMP-9 in lung tissue among groups were compared. RESULTS:The activity of mice in model group disap-peared,dull coat color,preferred crowding together;the above-mentioned phenomenon improved in positive control group and sal-vianolate different dose groups. The body weight of mice in positive control group,salvianolate low-dose group,medium-dose group and high-dose group were(21.01±2.95)g,(20.89±3.14)g,(21.03±3.02)g,(21.24±3.17)g;and the tumor inhibition rates were(41.12±15.42)%,(36.92±10.42)%,(39.41±12.39)% and(37.19±10.39)%;compared with model group,spleen index,thymus index,and the expressions of VEGF (except for positive control group) and MMP-9 in other 4 groups decreased (P<0.05). CONCLUSIONS:Salvianolate shows obvious inhibitory effects on mice with lung cancer,which may be related to in-hibiting expressions of VEGF and MMP-9 in lung tissue.
