大鼠帕金森氏病动物模型的建立 总被引:2,自引:0,他引:2
采用SD大鼠30只,25只为试验组,5只为对照组。在三维立体定向仪上用微量注射器将6-OHDA32μg分两点注射入右侧纹状体,每周检测动物的旋转行为,第1周动物没有出现旋转行为,第2周动物出现明显的旋转行为,随后缓慢上升;至术后5周才升至较高的水平并保持平稳。其中有15只动物达到或超过了7r/min这一通常采用的标准,模型成功率达60%。酪氨酸羟化酶免疫组化显示:术后第1周至第5周右侧黑质TH免疫反应细胞逐渐砬少,各个时期的右侧黑质TH免疫反应细胞较对侧明显减少。采用此方法建立的大鼠帕金森氏病模型更加符合临床PD病人的病程进展并明显提高成功率。 相似文献

The present study was conducted to evaluate some of the components of antioxidant defense system and oxidative damage in 20
male patients of alcoholic liver disease (ALD). The results were compared with 20 healthy male smokers and 20 healthy male
non-smokers volunteers. Patients were subjected to detailed clinical examination and laboratory investigations. Blood samples
were collected for estimating reduced glutathione (GSH), total thiols (T-SH) malondialdehyde (MDA), transaminases (AST, ALT),
glutathione-S-transferease (GST) and gammaglutamyl transferase (GGT). Serum aspartate amino transferase (AST)/alanine amino
transferase (ALT) ratio was significantly (p<0.01) reduced in ALD patients as compared to the controls. However, the core
of utility of MDA and GST was found to be significantly (p<0.01) increased in ALD patients compared to controls. There was
a significant negative correlation of MDA with both GSH and TSH. Plasma GGT levels were significantly (p<0.01) increased in
alcoholics and the enzyme showed a significant positive correlation with MDA. These results give enough evidence of increased
oxidative stress and compromised antioxidant defense system in patients with ALD. 相似文献

选择46岁以上的高血压(HBP)、冠心病(CHD)、卒中及其它内科住院病人共140名进行了血浆纤维蛋白原(FG)、血压、甘油三酯(TG)和吸烟等因素的观察.结果表明高血压、冠心病和车中患者FG值升高,逐步回归分析看出吸烟,HBP和TG水平升高明显影响FG的含量,提示FG水平升高同HBP,CHD和年中存在着紧密的联系。 相似文献

学生课业负担的许多客观事实显示,课程编制过程中存在着两级落差。从改革初衷到课程标准的第一级落差,主源自各自追求本学科可能发展区间的最大化以及总体协商、调控机制的缺乏;从课程标准到教科书的第二级落差,主源自某些标准的引申、充实、拓展失度,目标把握失当,教材都挤内容拓展一条道。控制落差的主对策是:降低课程编制的决策风险,加强实证研究,改进与完善评估机制。 相似文献

Objectives
There is much evidence showing that childhood adversities have considerable effects on the mental and physical health of adults. It could be assumed therefore, that the disease burden of childhood adversities is high. It has not yet been examined, however, whether this is true.Method
We used data of a large representative sample (N = 7,076) of the general population in the Netherlands. We calculated the disability weight (DW) for each respondent. The DW is a weight factor that reflects the severity of a disease or condition on a scale from 0 (perfect health) to 1 (equivalent to death). We used an algorithm based on the SF-6D to estimate DW. Because the DW indicates the proportion of a healthy life year that is reduced by the specific health state of the individual, it also possible to calculate the total number of years lost due to disability (YLD) in the population. We calculated the years lived with disability (YLD) for 9 different childhood adversities (in the areas of parental psychopathology; abuse and neglect; major life events), as well as for major categories of mental disorders and general medical disorders.Results
All 9 adversities resulted in a significantly increased DW, except death of a parent before the age of 16. Adversities in the category of abuse and neglect are associated with the highest DWs (0.057), followed by parental psychopathology (0.031) and life events during childhood (0.012). All adversities (46.4% of the population reports one or more adversity) are associated with 20.7 YLD/1,000, which is more than all mental disorders together (12.9 YLD/1,000). The category of abuse/neglect has the highest YLD/1,000 (15.8), which is also higher than all mental disorders together. Adjustment for the presence of mental and general medical disorders resulted in comparable outcomes.Conclusions
Childhood adversities are more important from a public health point of view than all common mental disorders together, and should be a priority for public health interventions. 相似文献58.
人体组成学是人体生物学的分支学科之一,主要研究人体内诸多组分的含量与分布、组分之间的数量关系、在活体中测定人体组分的方法、以及体内外各种因素对组分含量的影响。研究人体组成不仅具有生物学意义,也与提高国民体质、增进健康、治疗疾病密切相关。进入21世纪以来,海峡两岸对人体组成的研究呈快速发展的态势,每年平均发表58篇论文,约占全世界此领域论文总数的3.9%。这表明两岸的人体组成学研究,已在世界上占有一席之地。中国对人体组成的研究主要集中在3个方面:对中国人群身体组成特点的研究、对运动与身体组成关系的研究、以及对疾病与身体组成关系的研究。未来,两岸的人体组成研究应该在多方位发展,特别是研究更多的身体组分(如骨骼肌与内脏脂肪组织)、应用先进的测定方法、以及探讨黄种人的身体组成特点。第9届国际人体组成学研讨会于2011年在杭州举行,这必将进一步促进海峡两岸人体组成学研究的发展。 相似文献

Organic acidurias are an important class of inherited metabolic disorders arising due to defect in intermediary metabolic
pathways of carbohydrate, amino acids and fatty acid oxidation. This review summarizes the current knowledge about the important
organic acidurias in the Indian population. Specifically, diagnosis and principles of treatment of organic acidurias are covered.
The salient features of common organic acidurias as well as their prevalence in various parts of the world are reviewed in
some detail. 相似文献
