To explore the inhibitive effect of artemether on glioma growth and angiogenesis in brain tumor bearing SD rat. MTT assay was used to evaluate the inhibitory effect of artemether treatment on C6 glioma cells. Forty SD rats which were subcutaneous planted with SD rat C6 glioma cell to establish SD rat orthotopic glioma model were divided resourcefully into 5 groups. each group was 8 rats. Length-path (a mm) and short-path (b mm) of tumor each rat was measured. Tumor volume was calculated using the following formula: V (mm(3)) = a(2)bpi/6. Microvessel density (MVD) in different therapy groups was significantly lower than that in normal saline control group and brain glioma volume in different therapy groups was significantly smaller than that in normal saline control group. There were remarkably inhibitory effects of artmeter on brain glioma growth and angiogenesis in SD rats and the mechanism that artemether inhibited brain glioma growth might be penetrating the blood-brain barrier and inhibiting angiogenesis.
探讨蒿甲醚对荷脑肿瘤SD大鼠胶质瘤生长和血管生成的抑制作用。采用MTT法评估蒿甲醚处理对C6胶质瘤细胞的抑制作用。将40只皮下接种SD大鼠C6胶质瘤细胞以建立SD大鼠原位胶质瘤模型的SD大鼠随机分为5组,每组8只。测量每只大鼠肿瘤的长径(a mm)和短径(b mm)。肿瘤体积采用以下公式计算:V(mm³)=a²bπ/6。不同治疗组的微血管密度(MVD)显著低于生理盐水对照组,不同治疗组的脑胶质瘤体积显著小于生理盐水对照组。蒿甲醚对SD大鼠脑胶质瘤生长和血管生成有显著抑制作用,蒿甲醚抑制脑胶质瘤生长的机制可能是穿透血脑屏障并抑制血管生成。
