Methods Seven herbs of BYHWD were selected as the influencing factors, and they were Radix Astragali, Radix Paeoniae Rubra, the carda part of Radix Angelicae Sinensis, Pheretima Asiatica, Rhizoma Chuanxiong, Semen Persicae, and Flos carthami. Two levels were designed for each factor, and the experiment was arranged according to L8 ( 27) orthogonal test table. Apoptosis of PC12 cells induced by OGD was detected by serum pharmacology method and flow cytometry techniques. With apoptotic rate as the evaluation index, visual analysis and variance analysis were used for the comparison of apoptosis of PC12 cells in the blank control group ( oxygen + sugary medium + blank serum) , model group (oxygen-glucose-free medium + blank serum) and drug groups (oxygen-glucose-free medium +serum containing BYHWD or the separate recipe of BYHWD ) . Results Compared with the blank control group, apoptotic rate was increased in PC12 cells of the model group, the difference was statistically significant ( P<0.01) . Compared with the model group, the apoptotic rate was decreased in BYHWD group, and the differences was statistically significant (P<0.01) . The results of orthogonal analysis showed that Semen Persicae, Flos carthami and Radix Paeoniae Rubra were the main active ingredients of BYHWD on depressing apoptosis of PC12 cell induced by OGD ( P<0.01). The apoptotic rate of serum containing the prescription with Radix Paeoniae Rubra was lower than that of the prescription without Radix Paeoniae Rubra. Conclusion BYHWD could inhibit OGD-induced PC12 cell apoptosis, and Radix Paeoniae Rubra is the main active herb on depressing apoptosis in BYHWD.

    • 摘要: Objective To compare the effect of the decoction and capsule of Buyang Huanwu Recipe ( BHR) on protecting and repairing the neurons with global cerebral ischemia-reperfusion injury, and to explore the anti-oxidization mechanism. Methods Sprague-Dawley male rats were randomized into pseudo-operation group, model group, BHR decoction group (in the dosage of 10 g o kg-1 o d-1 ), and high-, moderate- and low-dosage BHR capsule groups (in the dosage of 7. 56, 3. 78, and 1. 89 g o kg-1 o d-1). Four-vessel occlusion method was used to establish the rat model of global cerebral ischemia-reperfusion injury. The effect of the decoction and capsule of BHR on the repair of pathological morphological structure of the hippocampal CA1 was observed. Meanwhile, serum and cerebral superoxide dismutase (SOD) activity and malondialdehyde content as well as the cerebral water content were measured. Results The decoction and capsule of BHR improved the pathological morphological structure of the hippocampal CA1 , and the effect of the capsule was better. Serum and cerebral SOD activity was increased and MDA content was decreased in the decoction group and the capsule groups (P <0. 01 compared with the model group), and the effect was better in moderate-dose BHR capsule group. Cerebral water content was decreased in the decoction and capsule of BHR groups (P<0. 01) , and the decrease was obvious in high-dosage BHR capsule group. Conclusion The decoction and capsule of BHR can protect the neurons from global cerebral ischemia-reperfusion injury, and the capsule has more reliable effect.%[目的]比较补阳还五汤复方胶囊与原方汤剂保护和修复大鼠全脑缺血再灌注损伤神经细胞的作用,并从抗氧化角度探讨其作用机制.[方法]选用SD雄性大鼠,随机分为假手术组,模型组,补阳还五汤原方汤剂组(剂量为10 g·kg-1·d-1),复方胶囊高、中、低剂量组(剂量分别为7.56、3.78、1.89 g· kg-1·d-1);采用4血管闭塞法复制全脑缺血再灌注模型,比较补阳还五汤复方胶囊和原方汤剂对海马CA1区病理形态结构的修复程度,并对血清及脑组织超氧化物歧化酶(SOD)活性、丙二醛(MDA)含量及脑组织含水量进行测定.[结果]原方汤剂组及复方胶囊各剂量组对海马CA1区神经元细胞病理形态变化均有康复改善作用,且复方胶囊中剂量组作用最为显著;在血清和脑组织中,原方汤剂组及复方胶囊组均可使SOD活性显著升高,MDA含量显著下降(P<0.01),且以复方胶囊中剂量组作用最为明显;原方汤剂组及复方胶囊各剂量组均可显著降低脑组织含水量(P<0.01),其中复方胶囊高剂量组作用最明显.[结论]补阳还五汤原方汤剂及复方胶囊对大鼠全脑缺血再灌注损伤均有保护作用,但复方胶囊疗效更为确切.

    • 摘要: [目的]观察补阳还五汤预干预对全脑缺血大鼠皮层神经元L型Ca2+通道的影响,探讨Ca2+信号异常参与缺血性神经元损伤的机制及补阳还五汤抗脑缺血的分子机制.[方法]72只SD大鼠随机分为12组,即假手术组(2组)、模型组和补阳还五汤组(此2组各分为缺血再灌注后2、12、24、48、72 h5个时间点组);补阳还五汤各组按0.64 g/kg剂量灌胃,每天2次,连续5 d.除假手术组外,各组均参照改良的Pulsinelli4血管闭塞法复制全脑缺血大鼠模型,缺血后的大鼠分别在存活2、12、24、48、72 h后进行皮层神经细胞急性分离,单通道电流经EPC-9膜片钳放大器放大,采用Pulse&Pulsefit采集入计算机,检测各组大鼠血流再灌注后不同时间点的L型Ca2+通道的平均开放时间和开放概率.[结果]模型大鼠皮层神经元L型Ca2+通道因缺血激活而开放,其开放时间在再灌后各时间点均比假手术组延长,开放概率分别在再灌注2 h和24h时出现高峰;而补阳还五汤组的皮层神经元L型Ca2+通道的开放时间在再灌72 h时比模型组降低(P<0.01),其开放概率在模型组出现第1个高峰时(再灌2 h)被显著性地降低至与假手术组相仿水平(与模型组比较P<0.01,与假手术组比较P>0.05).[结论]补阳还五汤在缺血再灌早期(再灌2 h),主要通过降低L型Ca2+通道开放概率,即影响L型Ca2+通道的可利用性以减少Ca2+内流.而在缺血再灌后期(再灌72 h),主要通过降低L型Ca2+通道开放时间,即影响L型Ca2+通道开放特性以减少Ca2+内流.
