目的:探讨帕金森病(PD)患者运动功能障碍的影响因素。方法:93例PD患者接受了调查。采用PD统一评分量表(UPDRS)评估患者各项运动功能障碍如震颤、肌强直、动作缓慢、面部表情、语言表达和中轴(步态和姿势)损伤。分析患者的性别、年龄、发病年龄、病程、受教育情况、治疗情况与UPDRS评分的相关性。结果:患者的UPDRS评分与认知水平和年龄显著相关;震颤与病程相关。回归分析显示患者年龄是影响UPDRS评分及中轴损伤的主要因素。结论:PD患者中轴损伤症状可能源于正常衰老和疾病本身共同作用的结果,在治疗中应重视老年患者的中轴运动损伤症状。 相似文献

为了观察16Hz、130dB次声对SD大鼠记忆功能的影响及依达拉奉对其脑损害的防治作用。依达拉奉干预组在次声作用前3d开始连续给药(3mg/kg)直至次声作用7d后停止。次声作用7d后,测Y型电迷宫评定大鼠记忆功能,用单链DNA(single-stranded DNA,ssDNA)免疫标记法检测海马内ssDNA阳性细胞(凋亡细胞)数,并通过透射电镜观察脑超微结构。结果发现次声作用后大鼠学习记忆功能下降、海马ssDNA阳性细胞数明显增多(与正常对照组相比,P<0.05);电镜下可见神经细胞出现较严重缺血、缺氧性改变,并可见不同时期凋亡细胞。依达拉奉干预组大鼠学习记忆成绩与空白对照组相比无差异;海马ssD-NA阳性细胞数较次声对照组明显减少,但仍较正常对照组多,差异均有统计学意义;电镜下细胞变性改变程度较轻。由此得到结论16Hz、130dB次声可引发大鼠的脑损伤、细胞凋亡、记忆功能受损,依达拉奉可明显减轻次声引发的这些损害。 相似文献

Objective: To investigate the effects of Lycium barbarum polysaccharide (LBP) on experimental gastric ulcers in rats. Methods: The ulcers were induced by water-immersion restraint stress, acetic acid and pylorus-ligation in rats. In each model, animals were divided randomly into 4 groups and administrated with LBP of 100 mg/kg and 300 mg/kg, ranitidine 100 mg/kg (as a reference standard) and saline respectively. Mucosal lesions were scored as ulcer index. In the pylorus-ligation model, we also compared the gastric juice volume, total acidity, acid output and pepsin activity among groups. Results: Oral administration of LBP inhibited the formation of the acute gastric lesions induced by physical stress such as water-immersion restraint (P＜0.05), and accelerated the healing of chronic gastric ulcer model induced by acetic acid (P＜0.05 to P＜0.01). In the pylorus-ligated rats, significant decrease was also seen in ulcer index (P＜0.05 to P＜0.01), total acidity (P＜0.05), acid output (P＜0.05 to P＜0.01). LBP 300 mg/kg even showed marked reduction of the volume (P＜0.05) and pepsin activity (P＜0.05) in the gastric juice. These effects were in a dose-dependent manner. Conclusion: LBP has protective effects on treating gastric ulcer and this action may relate to the reduction of acid output and pepsin activity in the gastric juice. 相似文献
