树鼩中脑腹侧被盖区向尾状核的DOPA能和AChE阳性纤维投射研究

应用荧光逆行标记分别与荧光组化(FAGLU)和AChE-药理组化相结合技术,研究了树鼩中脑腹侧被盖区向尾状核头部的DOPA能和ACHE-阳性纤维投射。结果表明:树鼩中脑腹侧被盖区除分别向同侧和对侧尾状核头部发出DOPA能纤维投射外,还向同侧尾状核头部发出AChE阳性投村纤维;此外,腹侧被盖区存在着向双侧尾核头部发出分叉投射纤维的DOPA能细胞。     

睫状体缝合复位术的临床观察及护理

目的:探讨适合睫状体缝合复位术病人的护理方法。方法:对34例(34只眼)因外伤致睫状体分离和脱离导致低眼压,随后行睫状体缝合复位术的病人进行观察和护理。结果:32只眼术后1周至6个月眼压恢复正常,其中5只眼术后2～5个月内分别进行第二次手术或氩离子激光光凝而痊愈。视力改善者21例,无变化者13例。结论:睫状体缝合复位术是治疗外伤性睫状体分离和脱离的有效方法。术前行超声生物显微镜(UBM)检查、术后密切观察眼压变化并给予正确处理、做好心理护理和出院指导是确保手术成功的重要措施。     

缝-脊5-羟色胺痛调制系统的形态学鉴定

<正> 在内源性痛调制系统中,中缝大核(NRM)及邻近结构的神经元轴突行向脊髓后角,其释放的5-羟色胺(5-HT)可能对后角内痛敏神经元,中间神经元以及初级传入     

Trephine craniotomy in neurosurgery]

For three years, we have performed craniotomy with a 5 cm diameter trephine through a linear incision. 53 craniotomies were done in 49 patients. This simple and time-saving method produced little bleeding and slight injury to the brain. The technique allowed the surgeon to spend most of his time at the management of lesion. Healing of wound was rapid and brain edema was minimal.     

Ketanserin降低清醒自发性高血压大鼠血压波动性的机理初探

应用计算机化清醒大鼠血流动力学测定技术，观察５－ＨＴ２受体阻滞剂Ｒｉｔａｎｓｅｒｉｎ（Ｒｉｔ）和α１受体阻滞剂哌唑嗪对清醒自发性高血压大鼠（ＳＨＲ）的血压、血压波动性（ＢＰＶ）和动脉压力感受性反射血压控制部分（ＡＢＲ－ＢＰ）的效应，旨在初步探讨兼具５－ＨＴ２受体和α１受体阻滞作用地新型抗高血压药Ｋｅｔａｎｓｅｒｉｎ降低ＢＰＶ的机制。结果表明：Ｒｉｔ对ＳＨＲ无降压作用，但侧脑室给药明显提高ＡＢＲ－Ｂ     

Does beta adrenergic blockade influence the prognostic implications of post-myocardial infarction exercise testing?

The influence of beta blockade on the ability of ST depression, during pre-discharge exercise testing, to predict coronary anatomy and subsequent complications was studied in 300 consecutive post-infarct patients, 125 of whom underwent cardiac catheterisation. At the time of exercise 62 patients were taking a beta blocker. The exercise test had a higher sensitivity in predicting multivessel disease in patients who were not taking beta blockers than in patients who were (95% v 76%). beta Blockade did not, however, influence the ability of the test to identify patients at risk of subsequent cardiac events (sensitivity 84% and 85% respectively). These results suggest that it is not necessary to stop treatment with beta blockers before predischarge exercise testing of patients who have had an acute myocardial infarction.
