Modulating effects of posttraining epinephrine on memory: Involvement of the amygdala noradrenergic system

These experiments examined the effects, on retention, of posttraining intra-amygdala administration of norepinephrine (NE), and propranolol. Rats were trained on a one-trial step-through inhibitory avoidance task and tested for retention 24 h later. Injections were administered bilaterally (1.0 microliter/injection) through chronically-implanted cannulae. Low doses of NE (0.1 or 0.3 microgram) administered shortly after training enhanced retention while higher doses (1.0 or 5.0 micrograms) were ineffective. Retention was not affected by NE administered 3 h after training. The effect of intra-amygdala NE on retention is blocked by simultaneous administration of propranolol (0.2 microgram). This finding suggests that the memory-enhancing effect of NE may be mediated by beta-receptors. Posttraining intra-amygdala NE also attenuated the retention deficit produced by adrenal demedullation. Further, intra-amygdala injections of propranolol (0.2 microgram) blocked the enhancing effect, on retention, of posttraining s.c. injections of epinephrine. These findings suggest that activation of noradrenergic receptors in the amygdala may be involved in memory processing and may play a role in the memory-modulating effect of peripheral epinephrine.     

膀胱癌的MRI诊断价值

目的:总结膀胱癌的MRI征象,探讨MRI对膀胱癌分期的作用及鉴别诊断要点。方法:对探讨经手术与病理证实23例膀胱癌的MRI回顾性对比分析。其中男性,19例,女性,4例,年龄50~90岁,平均年龄70岁。18例行MRI增强检查。结果:膀胱三角区及膀胱后侧壁是最常见好发部位,表现为膀胱壁突向腔内肿块和(或)膀胱壁局限性不规则增厚;肿瘤平扫T1WI等或略高信号,T2WI呈高信号,Gd-DTPA动态增强早期肿块显著强化。根椐肿瘤生长方式可分为:①小结节型,②广基肿块型,③浸润型。MRI对膀胱癌定位、定性诊断正确率分别为95.7%(22/23)、91.3%(21/23);术前MRI诊断与TNM分期符合率为82.3%(19/23),MRI较病理分期偏高。结论:膀胱癌的MRI表现具有独特性。T1加权主要用于肿瘤的定性诊断,T2加权主要用于肿瘤的术前分期;MRI检查多方位、多序列成像,是显示膀胱癌最理想的检查方法。     

保留盆腔植物神经对老年男性患者术后性功能及排尿功能的影响

目的:探讨保留盆腔植物神经的直肠癌手术对老年男性患者性功能及排尿功能的影响。方法:1999~2005年因直肠癌手术的170例老年男性患者分为PANP组(含规范的TME手术方法)和非PANP(TME规范情况不详),对两组术后性功能、排尿功能和局部复发率进行回顾性总结、比较。结果:PANP组性功能与排尿功能明显优于非PANP组,但统计学无显著差异(P<0.05)。而PANP组局部复发率低于非PANP组(P>0.05)。结论:老年直肠癌患者应重视性功能和排尿功能的保护。

去卵巢骨质疏松模鼠DPD及1,25-(OH)2D3与骨质量的相关性研究

目的：探讨雌性SD大鼠切除卵巢后机体尿DPD及血1，25-（0H）2D3变化与骨质量的相关性。方法：40X雌性SD大鼠随机分为卵巢切除组（OVX组）和假手术组（Sham组），分别于术后12、24周取材。运用双能X线骨密度仪测L1、股骨、股骨颈骨密度，ELISA法测尿DPD浓度，激素放免法测血1，25-（OH）2D3浓度，光测弹性仪测L1压缩强度极限、弹性模量及右侧股骨弯曲破坏栽荷，不脱钙骨切片技术观察胫骨上段骨组织形态结构并计量分析，对实验数据进行相关性分析。结果：术后OVX组除尿DPD／Cr明显升高外，其他检测指标均较Sham组低，且随术后时间推移持续下降，差异有统计学意义。相关分析显示：尿DPD／Cr与腰椎、股骨密度、椎体压缩强度极限、股骨弯曲破坏荷载和骨小梁面积均呈负相关。血清1，25-（OH）2D3水平与腰椎、股骨、股骨颈密度、骨小梁面积、椎体压缩强度极限和股骨弯曲破坏荷载呈正相关。结论：大鼠卵巢切除后尿DPD、血1，25-（0H）2D3水平变化与骨质量显著相关，可以通过检测尿DPD、血1，25-（0H）2D，水平变化预测骨质量。     

Case of acute urinary retention as a result of non-steroidal anti-inflammatory drugs

Abstract:   A 19-year-old woman presented at our hospital with acute urinary retention in September 2005. She had experienced the same chief complaint twice previously. She had used non-steroidal anti-inflammatory drugs before acute urinary retention. The results of physical examinations were unremarkable, and her neurologic signs were not remarkable. The basic laboratory test values were all normal and a psychiatric assessment indicated that her symptoms were not psychogenic. Magnetic resonance imaging was carried out, but revealed only a slight bulging in the L3/L4/L5 disk. Water cystometry showed acontractile detrusor. We made a diagnosis of acute urinary retention as a result of non-steroidal anti-inflammatory drugs because of her use of such drugs before the development of symptoms on multiple occasions. This patient was regularly followed up as an outpatient, and she could void smoothly in February 2006. This is the first report which acute urinary retention associated with non-steroidal anti-inflammatory drugs in Japan.
