麻木局部或全身的痛觉缺失，知觉或有或无，由麻醉药引起

The latter group showed marked pain, in particular, severe mechanical hyperalgesia, and predominantly small myelinated and unmyelinated fiber loss.

后一组突出表现为疼痛，特别是严重的机械性痛觉过敏，主要是小的有髓纤维和无髓纤维缺失。

The mean probability ofno response to pressure algometry was 23%± 35% whenpatients required fentanyl for pain control.

病人接受芬太尼来控制疼痛时对压力痛觉测定无反应的平均可能性是23%± 35%。

The patient was a 66-year-old male who presented with paraparesis. On examination, strength was 5/5 in both upper extremities and 3-4/5 in both lower extremities. Pricking sensation was relatively retarded below the sixth thoracic vertebra on both sides. Fine-touch sensation was limited below the ninth thoracic vertebra on the right side and below the eleventh thoracic vertebra on the left side. Responses to vibration and joint position sense were well preserved. Deep tendon reflexes were increased in his legs. He had voluntary anal contraction and preserved anal and bulbocavernous reflexes. MRI revealed dissection of the descending aorta from T4 to T10 levels with thrombus present in the false lumen, and the thoracic cord was marked atrophy, especially from T6 to T8 levels. To the best of our knowledge, no such case had been reported so far.

这是一位66岁的男性病患，到院时以下半身轻截瘫来表现，检查后发现其双上肢肌力为5/5而双下肢肌力则为3-4/5，刺痛觉在两侧第六胸椎以下异常，轻触觉在右侧第九胸椎与左侧第十一胸椎以下异常，震动觉与本体感觉则皆属正常，深肌腱反射在两下肢均有异常增强的情形，肛门的主动收缩正常且肛门反射与球体海绵体肌反射均正常，核磁共振影像显示降主动脉在T4到T10处有剥离的情形并於伪腔内发现血栓，此外，病患之胸部脊髓则有明显萎缩的现象，以T6到T8处最为明显，就目前可见的文献资料，并无类似的报告被提出。

E. , ACTH antagonizes the analgesia mediated byμand δ opioid receptors, but notκreceptor;(2) The antagonizing effect of ACTH on opioid analgesia is proposed to be mediated by ACTH receptors, although the latter has not been characterized;(3) A contradictory interaction on intracellular cAMP content may constitute one of the postreceptor mechanisms underlying ACTH antagonism of opioid analgesia;(4) Another proposed mechanism of the anti-opioid effect of ACTH is that ACTH can modulate opioid-induced suppression of calcium influx;(5) ACTH has been shown to induce Fos protein expression in selected areas of the rat brain including the nuclei involved in pain regulation as well as the ependyma of the third ventricle and the aqueduct.

根据以上实验结果，本论文首次提出以下论点：（1）ACTH在脊髓水平对抗阿片镇痛具有受体选择性，即ACTH可对抗μ受体和δ受体介导的镇痛，不对抗κ受体所介导的镇痛；（2）由于ACTH与阿片μ受体的肽类配体的结合位点仅有很低的亲和力，与μ受体的非肽类配体的结合位点以及δ受体无亲和力，推测ACTH是通过中枢内的ACTH受体介导发挥抗阿片效应的；（3）ACTH抗阿片作用的受体后作用机制之一是在cAMP信使通路水平与阿片发生相互作用；（4）ACTH抗阿片作用的另一受体后机制是在〓水平影响阿片的效应；（5）通过Fos蛋白的诱导揭示：ACTH可以作用于脑内多个核团，其中包括许多与痛觉调制有关的核团，推测ACTH可能通过激活这些核团的神经元而发挥其中枢效应。

Capsaicin excites nociceptive afferent nerves to produce warmth when initially applied, but with repeated application it desensitizes unmyelinated nerve fibers to produce hypalgesia without also causing patients to experience a reddening or blistering.

最初辣椒素刺激疼痛传入神经产生温暖，但通过它的反复刺激，使无髓神经纤维不敏感，从而产生痛觉迟钝，也没有造成患者能够体验到发红或者起泡。

"Sleep disruptions were similar in the NR and RD conditions, but did not involve REM sleep; the effects on pain threshold observed in the RD condition were therefore due specifically to the loss of REM sleep, not to the disruption of sleep per se," noted Dr. Roehrs."We found that REM loss itself was hyperalgesic."

Roehrs博士强调，在无快速眼动睡眠的因素下，NR及RD的睡眠干扰情况皆类似；在RD状态时，疼痛感受值会受到影响，这主要是因为丧失快速眼动睡眠的关系，而不是睡眠本身受到影响；我们发现，快速眼动睡眠的丧失，本质上就是痛觉过敏。

BACKGROUND: Spinally administered non- N -methyl-d-aspartate, but not NMDA, receptor antagonists block primary (1°) and secondary (2°) mechanical hyperalgesia and spontaneous pain after plantar incision.

背景：鞘内给予非 N-甲基-d-天冬氨酸受体拮抗剂可阻断足底切皮后原发性（1°）和继发性（2°）机械痛觉过敏和自发痛，而鞘内给予 NMDA 受体拮抗剂并无此作用。

Background: Oesophageal acid infusion induces enhanced pain hypersensitiity in non-acid exposed upper oesophagus in patients with non-cardiac chest pain, thus suggesting central sensitisation contributes to isceral pain hypersensitiity in functional gut disorders.

背景：非心源性胸痛的患者，在无酸暴露的上段食管因食管酸灌注可诱导痛觉高敏感，这提示在功能性肠道机能紊乱中，中枢致敏可导致内脏痛觉高敏感。

RESULTS: There were no significant differences in the median pinprick sensory block height [T4 (T4–2) vs T3 (T4–1)] or CSF pressures [6 (4–12) vs 9 (8–12) mm Hg] between the SSS and CSE groups.

结果： SSS 组和 CSE 组中位数痛觉阻滞平面高度[T4 (T4–2) vs T3 (T4–1)]或脑脊液压力[6 (4–12) vs 9 (8–12) mm Hg]无显著差异。

analeptic：兴奋剂

analbuminemia 无白蛋白血症 | analeptic 兴奋剂 | analgesia 痛觉缺失

anencephaly：无脑

analgesia 痛觉缺失 | anencephaly 无脑 | anesthesia dolorosa 痛性感觉缺失

Anesthesia：麻醉

这种使用是不够严谨的,麻醉(anesthesia)一词是1846年Holmes提出的,它的本意是使无知觉. 在医学中,麻醉的具体含义包括了镇痛、遗忘和意识丧失,就是指在麻醉药的影响下失去知觉,痛觉的暂时性消失是其主要目的. 所以,

Spinal Anesthesia：脊髓麻醉

下半身手术时常用的脊髓麻醉(Spinal Anesthesia)是把针穿过硬膜,再把麻醉剂注射进入脊髓液内. 常用在治疗背痛或无痛分娩接生用的硬膜外(Epidural)麻醉,针是停在硬膜外,所以注射时麻醉药是分散在外面邻近的神经纤维,使之麻痹及无痛觉.

Anacusis ; Anacousia：听觉缺失,聋

dysesthesia：感觉倒错

起强烈感觉感觉倒错(dysesthesia) 非疼痛刺激诱发出痛觉感觉过度(hyperpathia) 感觉的刺激阈增高感觉异常(paresthesia) 无外界刺激而发生的疼痛(pain) 任何过强的刺激均可引起疼痛瘫痪(paralysis)是指随意肌活动能力的减退或丧失,
