【摘要】 脑出血是指非外伤性脑实质内出血,属中医中风病之范畴。其患病人数约占所有脑卒中病人的20%~30%,住院死亡率往往高达43%~51%。且现在发病年龄呈年轻化的趋势,因此对脑出血的治疗和实验方面的研究日益受到关注。对于脑出血的治疗,中医有着独特的疗效。传统医学认为脑出血为风火相煽,痰湿蕴盛,瘀血阻滞致气血逆乱,上犯于脑而发病。因此中医治疗拟予化痰通腑、解毒通络、泻火熄风开窍、活血化瘀等法。安宫牛黄丸具有清热解毒、镇惊开窍之功效,在临床上对于脑出血的治疗有很好的疗效。方中朱砂、雄黄由于含有重金属化合物,历来是大家争议的焦点。中医理论认为:雄黄具有清热解毒、化瘀消积的功效,朱砂具有清心镇惊,安神解毒的功效。从二者的功效上看,与中医治疗出血性中风的治法相一致,因此北京市科委立专项(项目编号:H040230130712)探讨含与不含朱砂雄黄的安宫牛黄丸在药效上的区别,以明确朱砂、雄黄在安宫牛黄丸方中存在的意义。本论文研究的主要内容包括两部分:第一部分采用大鼠脑出血损伤动物模型,从整体水平观察含与不含朱砂雄黄的安宫牛黄丸对大鼠脑出血损伤的保护作用并探讨其机制;第二部分从细胞水平观察含与不含朱砂雄黄的安宫牛黄丸含药血清和含药脑脊液对原代皮层神经元的保护作用并探讨其机制。第一部分含与不含朱砂雄黄的安宫牛黄丸对大鼠脑出血损伤的保护作用及机制研究建立胶原酶诱导大鼠脑出血损伤动物模型,观察安宫牛黄丸对大鼠脑出血损伤的保护作用,并探讨其可能机制,同时以不含朱砂雄黄的安宫牛黄丸与之对比,观察去掉朱砂雄黄之后作用与全方是否存在差别。1含与不含朱砂、雄黄的安宫牛黄丸对脑出血大鼠保护作用的研究目的:研究安宫牛黄丸对脑出血模型大鼠神经症状、脑系数、脑含水量、全血的血液流变性、抗氧化能力、病理形态学的影响。同时观察不含朱砂雄黄的安宫牛黄丸与之是否存在差异。方法:采用尾状核注射胶原酶(TYPEⅣ)脑出血模型大鼠,于术后第3天进行神经病学症状评分;称重法测定脑系数;干湿重法测定脑含水量;生化试剂盒检测脑组织匀浆中LDH、SOD活性,MDA含量;血流变仪进行血液流变学检测;HE染色进行病理形态学观察。结果:(1)模型组动物神经功能症状评分、脑指数、脑含水量增加;红细胞变形性降低;LDH活性升高,SOD活性降低,MDA含量增加;损伤侧脑组织可见出血、水肿,血肿周边脑组织呈大片变性、坏死,神经细胞肿胀等明显病理形态学改变。(2)安宫牛黄丸200mg/kg、400mg/kg可显著改善神经症状评分(与模型组比,p<0.01,

【Abstract】 Intra-cerebral hemorrhage （ICH） is also called non-wounded cerebral hemorrhage. It belongs to one of the category of stoke. Among all the stroke patients, the number of ICH patients is going up to 20%³0%, and the hospital mortality has reached 43%⁵1%. Nowadays, the onset age of ICH tends to be younger, therefore, more and more attention is attracted to the research on prevention and therapy of ICH. Generally speaking, ICH is caused by the attack of both wind and fire, and the dampness is more one bad factor.With regard to the therapy on ICH, Traditional Chinese Medicine （TCM） has its own unique curative effect. The basic principle of TCM is to apply different prescriotions to treat different patients, that is to say, disease and syndrome are taken into account all together when facing different patient.Angongniuhuang pill （AGNHW）, the fomous Chinese medicine has remarkable effects of removing heat and cleaning toxin, so it has good curative effect on ICH. But for a long time, it is argued whether it is necessary to add Cinnabaris and Realgar into the medicine because of their huge toxicity. Therefore, We design a series of experiments so as to clarify the difference of AGNHW with Cinnabaris and Realgar and AGNHW without Cinnabaris and Realgar （QZX-AGNHW）.

Methods: Using cell damage models induced by oxygen/glucose deprivation and GLU,the serum and cerebrospinal fluid pharmacological methods were determined, in order to observe the function of cinnabar and realgar. Results: （1） The damage of oxygen-glucose deprivation increased the leakage rate of LDH. （2）observe morphocytological chages and measure the LDH leak rate , cytoactive , intracellular concentration of MDA and SOD. In the cells injured by the oxygen/glucose deprivation,LDH leak rate was significantly increased, while the cytoactivty was inhibited. These changes were blocked effectively by serum and cerebrospinal fluid containing AGNHW, especialy by the dose of 800mg/kg,and the cerebrospinal fluid with the additive proportion of 20% is better than the same dose. The result indicated that the effection of AGNHW is better than that of QZX-AGNHW. After cells were injured by GLU,LDH leak rate was also significantly increased,meanwhile, the cytoactive was inhibited,and morphocytologic changes were observed obviously. AGNHW had the significant protective actions when the dose reached 640mg/kg,and the cerebro spinal fluid with the additive proportion of 20% was better using the same dose. Conclusion: AGNHW has significant effects of protecting cells.5 The effects on mitochondria membrane potential and intracellular Ca²⁺ concentration of rat cortical neurons injured by GLU of AGNHW and QZX-AGNHWObjective: To observe the effects of AGNHW and QZX-AGNHW on mitochondria membrane potential and intracellular Ca²⁺ concentration of rat cortical neurons injured by GLU. Methods: Using the method of flow cytometry（FCM）,mitochondria membrane potential and intracellular Ca²⁺ concentration of rat cortical neurons were measured, then the effects of AGNHW and QZX-AGNHW were compared on the basis of the above data. Results: In rats whose cortical neurons were injured by GLU,mitochondria membrane potential was observed to decrease,and the concentration of intracellular Ca²⁺ raised. The value of mitochondria membrane potential could be increased by AGNHW and QZX-AGNHW containing serum and cerebrospinal fluid. While the concentration of intracellular Ca²⁺ reduced evidently when acted by AGNHW containing cerebrospinal fluid and QZX-AGNHW containing serum and cerebrospinal fluid. Conclusion: AGNHW and QZX-AGNHW had the similar effects, which produced the protective effects on injuryed neurons through stabilizing mitochondria membrane potential and blocking calcium overload.6 Determination of Concentration of cinnabar and realgar in serum and CSF of AGNHW and QZX-AGNHWObjective: To determine whether As and Hg contained in cinnabar and realgar were absorbed into blood or cerebrospinal fluid （CSF） through BBB. And further to analyze if cinnabar and realgar play an important role in the protective effect of AGNHW. Methods: Inductively Coupled Plasma-mass was used to determine the concentration of As and Hg in serum and cerebrospinal fluid . Results:（ 1） As in AGNHW could be tested in blood and might be absorbed into the CSF through BBB. The content of As in serum is 5.26 times that of As in CSF.（2） Trace As could be tested in serum and CSF of normal control group and QZX-AGNHW group.（3） The content of Hg was very near the limit of detection of instrument, so it could not be detected exactly. that is to say, the content of Hg need more accurate methods to be detected. Conclusion: Both Serum and CSF Contaning Drug of AGNHW contained As and Hg,the difference of neuro protective effect of AGNHW and QZX-AGNHW had relationship with As and Hg.In summary, AGNHW alleviated the neurologic symptoms of rats after ICH; amelioration morphology changes induced by ICH; reduce cerebral index , improve erythrocyte deformability, all these results show its satisfactory protective effect to experimental ICH.

It has the function of anti-apoptosis by increasing the express of Bcl-2,and decreasing the express of Bax. It can surpression the expression of c-fos,c-jun,PKC,elevate the mRNA expression of ERK and decrease the mRNA expression of P38.their specific receptor. It can surpression the expression of AQP4,MMP9.Compaired with AGNHW , the function of QZX- AGNHW of increasing nerve symptoms, decreasing cerebral index was weakened .And the function of anti-apoptosis of QZX- AGNHW is not notable.In this experiment ,we studied the protective effect of AGNHW and QZX- AGNHW to ICH rats.1 In this study, the protective function of AGNHW and QZX-AGNHW on rats injured with ICH was analyzed. Accordingly entirety pharmacodynamics,serum phamacology and CSF phamacology , the effective differences of the two kinds of medicines were compared. The results show that cinnabar and realgar play an important role in the total prescription.2 Based on the experiments of the mechanism analysis, AGNHW and QZX-AGNHW have the similar effects, which produce the protective effects on injuryed neurons through anti-apoptosis and blocking calcium overload. 3 For the first time, it is reported that the effection of AGNHW and QZX-AGNHW on the pathway of signal transconduction of MAPK.更多还原
