由于细胞 、组织和器官的功能依赖于正常的血液循环及血液灌流 ,因此 ,微循环障碍是引起器官功能障碍甚至衰竭的主要因素。研究表
明 ,高分子右旋糖苷(Dex tran 500)在导致大鼠微循
环障碍及血液流变性异常的同时 ,可引起大鼠肝 、
肾 、肺等器官组织形态学损伤[ 1] ;夏至草可明显改善
血瘀大鼠的血液和淋巴微循环障碍[ 2 , 3] 。为了进一
步探讨夏至草对急性微循环障碍大鼠器官损伤的干
预机制 ,本文观察夏至草醇提物对 Dex tran 500 致
大鼠急性微循环障碍时肝 、肾 、心肌 、肺组织一氧化
氮(NO)及其合酶(NOS)的影响 。
1 材料与方法
1.1 动物与分组
Wistar大鼠 20只 ,体质量 240 ~ 300 g(中国医
科院实验动物繁育中心提供),随机分为夏至草组(n
=8)、模型组(n=6)和对照组(n=6)。前二组以
Dex tran 500复制急性微循环障碍模型 。
1.2 夏至草醇提物制备
唇形科夏至草属植物夏至草[ mrrubium inci-
sum Benth]的全草(内蒙驻张家口医药站提供 ,经
河北北方学院中医系姜希强教授鉴定),按文献[ 4] 报
道方法 ,制备夏至草醇提物 ,经水煎醇沉 ,再经活性
炭脱色 、灭菌制成原生药含量为 5 g/ml的注射液
(pH 、澄清度 、溶血试验检测均为合格)。
1.3 急性微循环障碍模型的复制
所有大鼠均以 2%戊巴比妥钠溶液(北京化学
试剂厂生产 ,批号 20000919 , 50 mg/kg 体重)肌注
麻醉后 ,行颈部正中手术切口 ,剥离左颈静脉和右颈
总动脉 ,插管 ,备注射 、输液及放血用 。稳定 15 min
后 ,夏至草组及模型组大鼠应用 WZF-50F2双道微
量注射泵(浙江大学医学仪器有限公司)以 10%的
高分子右旋糖苷(Dex tran 500 ,瑞典 Pharmacia Bio-
tech ,10 ml/kg 体重)经左颈静脉缓慢匀速推注 , 1
min 注完 , 成功复制急性微循环障碍模型[ 5 , 6] 。6
min 后 ,夏至草组经微量注射泵由颈静脉缓慢推注
夏至草醇提物(6 g/kg 体重 ,以等量生理盐水稀
释);模型组输入与夏至草醇提物等量的生理盐水;
输液时间为 5 min。对照组以等量生理盐水代替
Dex tran 500和夏至草醇提物。
1.4 标本制备及指标检测
经夏至草醇提物治疗或相当于治疗 40 min后 ,
分别处死动物。选择各组大鼠的肝 、肾 、心肌 、肺组

高速分散均质机(FJ-200 ,上海标本模具厂)低温制
备 10%组织匀浆 ,应用高速低温离心机以 2 500 r/
min离心 10 min ,取上清液置于冰箱内-80℃冷冻
备测。应用硝酸还原酶法 、化学显色法分别检测各
组动物各脏器组织匀浆 NO -2 /NO -3 含量及 NOS 活
性(试剂盒购自南京建成生物工程研究所),严格按
照试剂盒说明书要求进行操作。各脏器组织匀浆蛋
白以考马斯亮兰法进行定量 。

3 讨 论
高分子右旋糖苷所导致的微循环障碍以及凝血
功能紊乱是引起肺 、肾 、肝等多个器官的功能障碍 ,
诱发多器官功能障碍综合征(Multiple Organ Dys-
function Syndrome , MODS)的主要因素之一[ 1] 。
因此 ,从改善微循环障碍以及血液流变性异常来寻
找药物和其他有效措施正成为医学研究的重要课题
之一。夏至草具有利水消肿 、活血化瘀作用[ 7] ,应用
夏至草可明显改善大鼠的淋巴微循环障碍[ 8] 。为
此 ,本研究从 NO角度观察夏至草醇提物对急性微
循环障碍大鼠器官损伤的影响 ,并阐明夏至草的药
理学作用 。
NO作为一种具有多重生理功能的介质 ,在参
与调节血管和气管平滑肌舒张 、机体免疫防御 、细胞
溶解等诸多方面发挥重要作用[ 9] ,降低 NO 的生成
释放可改善内毒素休克的低血压[ 10] 。本研究结果
表明 ,给予 Dex tran 500后 ,模型组肝 、肾 、心肌 、肺
组织匀浆的NOS活性及 NO 含量增高 ,其机制可能
为 Dex tran 500 在引起大鼠急性微循环障碍的同
时 ,加重了组织细胞的缺氧以及酸性产物潴留 ,刺激
组织诱导型一氧化氮合酶(iNOS)表达增强 , NOS
活性增高 ,诱导内皮细胞 、巨噬细胞 、中性粒细胞形
成大量的 NO ,从而引起 NO 的释放增多;大量的
NO 发挥其损伤作用 ,加重炎症反应 ,通过刺激中性
粒细胞产生呼吸爆发及脱颗粒 ,释放氧自由基和蛋
白水解酶 ,作用于内皮细胞 ,引起组织器官损伤 。输
入夏至草醇提物后 , 各脏器组织匀浆 NO 含量及
NOS活性均显著低于模型组 ,提示输入夏至草有效
地抑制了NOS 活性表达 ,从而减少 NO的产生和释
放 ,这主要是由于夏至草醇提物具有良好的改善微
循环作用 ,减轻了 Dextran 500致大鼠的急性微循
环障碍[ 3] ,从而缓解细胞的缺氧 ,抑制 NO 产生 ,减
轻 NO 引起的炎症反应 ,降低 NO 对组织细胞的损
伤 ,最终达到保护器官功能的作用。
综上所述 ,夏至草醇提物对 Dex tran 500 致急
性微循环障碍大鼠具有较好的保护作用 ,其机制与
夏至草可有效改善微循环流态[ 3] 、改善细胞缺氧状
态 ,从而抑制 NO 的产生 、减轻组织细胞的炎症损伤
有关 ,这为深入研究夏至草醇提物的药理学作用提
供了实验依据 ,也为以活血化瘀类中药为靶标治疗
微循环障碍类疾病治疗提供了新思路 。

国内外大量资料表明 ,脂质代谢的紊乱 ,尤其是
TC 的升高是动脉粥样硬化的重要原因[ 5 , 6] 。我们
对临床已确诊的中老年冠心病患者 ,经服用汤药治
疗后 ,其实验室观察指标表明 TC 、LDL-C 、ApoB 降
低 ,ApoA1升高 ,与治疗前比较差异有显著性意义 ,
表明此方经临证加减后能明显降低血胆固醇的水
平 ,有助于改善血脂代谢 ,而对 E2的代谢影响不大 。
有关资料也证实川芎 、赤芍 、益母草等活血化瘀中药
能降低血胆固醇 ,降低血小板聚集 ,改善血液粘稠度
和高凝状态[ 7] 。周建英等[ 8]对补阳还五汤进行拆方
研究 ,发现该方对高脂血症动物模型具有明显的降
脂作用 。近年来随着对补阳还五汤药理作用的不断
研究 ,发现该方在心血管系统有更广泛的应用 ,尤其
对治疗 CHD 取得了满意的疗效[ 9] ,值得进一步研
究 。

w as performed to ident ify risk factors for CHD in diabetic pat ients.The
predictive value of hemoglobin A (1c)and Lipoprotein-a for presence of
CHD in diabetic patients was calculated by constructing receiver-operating
characterist ic curves(ROC).Results:Serum level of hemoglobin A (1c)(7.5±1.4)% and Lipoprotein-a(0.25±0.19)g/ L in diabetic patients
wi th CHD w ere significant ly higher than those in patients with diabetes
only(6.9±1.4)% and(0.19±0.16)g/ L , P<0.05.Mult ivariate logi s-

may be useful in predicting the relative risk for CHD in patients wi th type
