| 目的 :观察补阳还五汤 (消栓口服液 )对饲料所致动脉粥样硬化兔模拟经皮冠脉腔内血管成形术 (PTCA)后再狭窄有无防止的作用。方法 :动物随机分中药组 2 4只和对照组 2 0只 (另 4只术中死亡 )。中药组术前 1周至术后 4周喂药 2ml/ (kg·d) (含生药 8 4 g/ml) ;对照组喂同量生理盐水。两组均在腹主动脉用球囊法模拟PTCA。结果 :术后 60天中药组和对照组受损血管内膜增生发生率分别为 2 9 2 %、85 0 % ;内膜增生面积分别为 ( 0 54± 0 2 1)mm2 、( 1 67± 0 75)mm2 ;内膜增生百分比为 ( 18 0± 7 2 ) %、( 56 0±17 1) % ;管腔相对面积比为 ( 0 74± 0 0 3) %、( 0 35± 0 0 7) %。以上差异均有显著性 (P <0 0 1)。含药血清对血管平滑肌细胞培养的3H TdR掺入有显著抑制作用 ,中药组和对照组分别为 ( 4 110 14± 1977 0 1)cpm、( 7960 14± 2 80 2 59)cpm(P <0 0 5)。 结论 :补阳还五汤 (消栓口服液 )对饲料所致动脉粥样硬化兔模拟PTCA后再狭窄有显著防止作用。 |

| Objective: To examine the preventive effect of Buyang Huanwu Decoction (BYHWD) on imitative restenosis after percutaneous transluminal coronary angioplasty (PTCA) in diet induced atherosclerotic rabbits.Methods: Diet induced atherosclerotic rabbits were randomly allocated into group 1 (n=24, fed with BYHWD one week before and 4 weeks after the operation, 2ml/kg per day, containing herbal drug 8.4 g/ml) and group 2 (n=20, as control). Balloon angioplasty was performed in the abdominal aorta to mimic coronary angioplasty. Results: Sixty days after operation: (1)Incidence of hyperplasia of the intima was 7/24 (29.2%) in group 1 vs 17/20 (85.0%) in group 2, P<0 01; (2) Comparison of area of hyperplastic intima was (0 54±0 21)mm 2 vs (1 67±0 75) mm 2, P<0 01;(3)Area of hyperplastic intima/area of lumen (limited by the internal elastic membrane was (18 0±7 2)% vs (56 0±17 1)%, P<0 01; (4) Intact lumen/dilated lumen was (0 74±0 03) vs (0 35±0 07), P<0 01; (5)Effect of serum taken from group 1 on cultured smooth muscle cells showed by 3 H TdR method was (4110 14±1977 01) cpm, which was significantly less than that of serum taken from group 2 〔(7960 14±2802 59) cpm,P<0 05〕. Conclusion: BYHWD has significant preventive effect on the imitative post PTCA restenosis in diet induced atherosclerotic rabbits. |
