正常人口腔粘膜不同部位表面感觉的测试

目的 建立正常人口腔粘膜不同部位表面感觉的正常参考值，并测试各年龄组感觉值是否存在差异。方法 利用动静两点辨别觉试验，测试90例健康人口腔粘膜不同部位的表面感觉。结果 舌尖感觉功能最好，其次为舌背、舌腹、颊粘膜、口底和硬腭。健康人的口腔粘膜不同部位的表面感觉随着年龄增长有显著性变化。结论 口腔粘膜不同部位感觉辨别力存在差异，健康人口底、舌腹、舌背、颊和硬腭粘膜感觉功能有增龄性变化。     

Long-term follow-up of hypothalamic-pituitary function in patients with transsphenoidal pituitary herniation and midfacial anomalies.

OBJECTIVE: We wished to determine whether patients with transsphenoidal pituitary herniation were at risk of developing pituitary failure. DESIGN: We followed up hypothalamic-pituitary function annually in patients with midfacial anomalies and pituitary herniation. PATIENTS: Two patients who had transsphenoidal pituitary herniation and midfacial anomalies were included and the literature was reviewed. RESULTS: Both patients became gonadotrophin, TSH and growth hormone-deficient despite neurosurgical repair. CONCLUSION: We conclude that the early diagnosis and neurosurgical repair of transsphenoidal pituitary herniation may prevent central nervous system infection and rhinorrhoea. Surgical repair may not prevent pituitary failure as was evident in both of our cases. Periodic evaluation of the hypothalamic-pituitary axis is essential to determine whether early hormonal replacement therapy is necessary.     

京剧器乐的听力损伤（附55例调查报告）

本文对从事京剧打击乐的55人（110耳）进行了听力调查及动态观察。利用图表进行对比分析，发现110耳中高频听力损伤89耳，占81％；语频听力损伤32耳，占29.1%；其中伴有高频耳鸣78耳，占70．9％。动态观察30人（60耳），均为永久性听阈阈移。高频听力损伤最早出现的频率是4kHz，并见典型“V”谷，符合噪声性聋的诊断。     

癫痫持续状态大鼠的蓝斑组织化学与图像分析研究

作者用马桑内酯致大鼠癫痫持续状态,取蓝斑用荧光组织化学方法显示去甲肾上腺素(NA),并用显微摄影自动曝光时间和图像分析两种方法测定荧光强度。结果:均显示大脑皮质包埋马桑内酯微粒的大鼠癫痫持续发作6小时后,蓝斑中NA荧光增强。用单胺氧化酶组化和图像分析法观察到该处酶活性增强。观察到在癫痫持续状态时NA起了一定的调控作用。     

Concurrent quantification of tissue metabolism and blood flow via 2H/31P NMR in vivo. III. Alterations of muscle blood flow and metabolism during sepsis.

In the conclusion of this series of reports, the application of 31P/2H NMR to investigate the pathophysiology of sepsis in rat hindlimb muscle is demonstrated. Sepsis decreased muscle [PCr] by 18%, 18 +/- 4 SD vs 22 +/- 4 SD mmol/kg tissue wet wt (P = 0.01) in control rats but [ATP] was unchanged, 6 mmol/kg tissue wet wt (P = 0.2). The derived free cytosolic [ADP] in the two groups was similar, [ADP]septic = 0.023 +/- 0.004 SD and [ADP]control = 0.021 +/- 0.003 SD mmol/kg tissue wet wt, and not statistically different (P = 0.14). Likewise [Pi] in the septic and control groups was not statistically different, [Pi]septic = 1.1 +/- 0.5 SD and [Pi]control = 1.2 +/- 0.4 SD mmol/kg tissue wet wt (P = 0.2). Septic rats presented the symptom of respiratory alkalosis evidenced by elevated blood pH. Sepsis decreased muscle blood flow by 33%, P = 0.003, but examination of individual subjects did not demonstrate a correlation with the reduction in [PCr]. Thus, a metabolic energy deficit caused by cellular ischemia/hypoxia is not a likely cause of cellular abnormality in rat hindlimb muscle during sepsis.     

恒猴精索内注射长效局麻药后对睾丸和附睾的影响

在13只恒河猴精索内注射长效局麻药后,睾丸发生明显变化;而且给药剂量不同,睾丸曲精小管改变的程度和恢复正常的时间亦不同。睾丸间质细胞无明显变化;睾酮分泌不减少,无毒性反应。对临床男性节育应用及生殖生理研究均具有意义。     

305例老年死亡病例医院感染回顾性调查

本文结果表明,305例老年死亡病例医院感染的发病率为33.8％。感染最多部位为肺部(66.9％),其次为尿路感染(19.4％)。高龄患者,侵袭性操作、多种抗生素联合应用,激素疗法等是诱发医院感染的危险因素。58.8％的病原菌为革兰氏阴性杆菌,37.2％为真菌。31株病原菌药敏结果显示耐药率为33.3％。本文指出合理应用抗生素是预防医院感染的重要措施之一。

Overgrowth of a costochondral graft in reconstruction of the temporomandibular joint.

We report the case of a 3-year-old girl with temporomandibular ankylosis, which was treated with a costochondral graft and required two further resections because the grafted tissue had overgrown.     

隐睾患儿血清FSH、LH、T水平及其临床意义

目的研究隐睾患儿血中促卵泡激素(FSH)、促黄体激素(LID和睾酮(T)激素水平变化,探讨其临床意义及在隐睾症发病中的作用。方法应用化学发光免疫技术检测42例隐睾症和23例斜疝(对照组)患儿血清FSH、LH、T水平。结果单侧隐睾症组和斜疝组之间血清FSH、LH和T水平无显著性差异(P＞0．05)；(2)双侧隐睾组血清FSH水平高于斜疝组,差别有统计学意义(P＜0．05)；单侧隐睾症组血清FSH高于斜疝组,低于双侧隐睾症组,差别无统计学意义(P＞0．05)。结论(1)血清中性激素LH和T水平的变化在隐睾发生中并不起主要作用；(2)血清FSH水平的升高可能反映睾丸功能损害严重程度。
