目的 探讨提高6-羟基多巴胺帕金森病大鼠模型成功率的方法 ,并从行为学、黑质多巴胺神经元形态学角度对模型进行评价.方法 取SD大鼠90只,将6-羟基多巴胺立体定向微量注射于左侧黑质区及黑质纹状体通路,观察大鼠的行为及黑质细胞形态学变化.结果 ①90只大鼠中经阿朴吗啡诱导后有64只(占71.1%)恒定转向右侧且结果 稳定,旋转圈数>210r/30min,被认为是成功的帕金森病大鼠模型;②除旋转行为外,部分大鼠还出现震颤、活动迟缓、嗅探、觅食、竖尾等异常表现;③随机选取10只不同时期的成功帕金森病大鼠模型,免疫组化下观察发现注射侧黑质区多巴胺能神经元较对侧明显减少(P<0.001),电镜观察发现大鼠中脑黑质神经细胞普遍存在变性坏死及不同阶段的凋亡样改变.结论 用6-羟基多巴胺选择性损毁黑质多巴胺能神经元可较快建立稳定的成功率较高的类似于人类中晚期帕金森病行为和病理的大鼠模型,但在病程和行为学等方面同帕金森病人仍有许多差异.  相似文献

王健  彭国光 《重庆医学》2003,32(6):729-731
目的 初步观察培高利特对大鼠黑质多巴胺神经元的保护作用,并探讨其可能的机制。方法 通过立体定位注射6—羟基多巴胺(6-OHDA)制作帕金森病大鼠模型,观察预先注射培高利特对阿朴吗啡诱发的旋转行为及受损侧黑质病理变化的影响。结果 大鼠持续注射培高利特7d后可明显减轻PD大鼠的旋转行为,并对抗6-OHDA所致只质多巴胺神经元的减少。而选择性D2受体桔抗剂氨黄酰基苯甲酰胺化合物(Sulpiride)可阻断培高利特的保护效应。结论 培高利特对多巴胺神经元具有保护作用,其机制可能与刺激多巴胺D2受体有关。  相似文献

CASE HISTORY A female patient, 46 years old, head of the foreign affairs department of a certain university in Beijing, paid her first visit on October 9, 2006, with the chief complaint of vomiting for one month. She got vomiting after meals in early September. Before that, she had discomfortable sensation in the stomach due to angry with others, but she didn't pay much attention. Later, it developed into vomiting after eating. After the vomiting, the discomfort would be relieved, but with slight hypodynamia. She was once diagnosed as having 'neurogenic vomiting'. Having taken some western and Chinese drugs, the above symptoms were a little bit improved, but she would have nausea upon eating and with regurgitation. Because of the fear for vomiting, she did not dare to have food intake, with body weight reduction of 6 kilos in one month.  相似文献

OBJECTIVE: To observe therapeutic effects of the comprehensive therapy of acupuncture-moxibustion and Chinese Tuina for treatment of insomnia due to deficiency of both the heart and spleen. METHODS: 92 cases were divided randomly into the treatment group (treated by acupuncture-moxibustion and Chinese Tuina) and the control group (treated by acupuncture-moxibustion). RESULTS: The therapeutic effect of the treatment group was obviously superior to that of the control group (the CHI2 test showed P < 0.01). CONCLUSIONS: The comprehensive therapy of acupuncture-moxibustion and Chinese Tuina can give marked therapeutic effects for treatment of insomnia due to deficiency of both the heart and spleen.  相似文献

Evidence obtained from randomized controlled trials (RCTs) has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine (TCM) and results have shown that there is an urgent need for higher quality RCTs on TCM.  相似文献
