刺五加对~(60)Co-γ射线照射后小鼠胸腺效应的实验研究

采用180只成年小白鼠(雌雄各半),其中168只经一次总剂量为4Gy的~(60)Co—γ射线照射,造成造血放射损伤,再从其中随机选出56只膜腔注射刺五加注射液作为实验用药组,其余小白鼠随机分为盐水对照组(56只),空白对照组(56只)及正常对照组(12只)。实验结果显示。实验用药组的胸腺细胞超微结构的恢复比同期对照组快,胸腺组织DNA含量比同期对照组高。因此,我们认为刺五加可促进辐射损伤后小白鼠胸腺细胞结构的恢复。     

磁场对家兔急性实验性高血压的影响

目的 :探讨内关穴敷磁的降压效应。方法 :40只清醒家兔和 40只麻醉家兔 (其中 2 0只去减压神经 ) ,静脉注射去甲肾上腺素或苯肾上腺素引起急性实验性高血压 ,并于内关穴敷磁 (0 .1～ 0 .2T) ,记录血压、心率和敷磁前及 1h后的血液粘度的变化。结果 :敷磁 1h后各实验组平均动脉压 (MAP)显著下降 (P <0 .0 1)。麻醉和清醒家兔MAP降幅无差异 (P >0 .0 5 ) ,但显著高于去减压神经家兔MAP的降幅 (P <0 .0 1或 0 .0 5 ) ,各实验组全血比粘度显著下降 (P <0 .0 1或 0 .0 5 ) ,实验组与各自对照组心率敷磁前后无差异 (P >0 .0 5 )。结论 :磁场具有降压作用 ,但对心率无影响 ,其降压效应与减压神经的抑制和全血粘度的降低有关 ,与化学感受性升压反射无关     

肋骨骨折与肺挫伤

本文总结48例肋骨骨折合并肺挫伤。其中43例为多根多处肋骨骨折伴肺挫伤．5例为单处骨折伴肺挫伤。临床资料表明多根多处肋骨骨折（连枷胸）的伤员之呼吸窘迫症状并不经常和肋骨骨折数目成正比。连枷胸所见的呼吸窘迫，低氧血症及肺内分流增加。主要是肺挫伤导致的肺实质性损害引起，而非胸壁反常运动造成。早期充分的止痛是有效的治疗方法。     

驼背二种截骨术远期效果对比

作者对６３２例强直性脊柱炎并驼背畸形施行二种脊柱截骨矫治术，对其中１３５例病人进行了６～１０年观察，结果表明：７１例椎弓椎体联合截骨效果较好，驼背复发平均３．２°。而６４例椎板截骨效果略差，驼背平均复发１３．５°。经统计学处理，两者对比有显著的统计学意义（ｐ＜０．０１）。作者认为病变未完全静止，截骨术式的选择，术中身体重心前移未彻底纠正，以及外固定时间过短等是影响远期效果的因素。     

Irreversible drop of systemic vascular resistances in patients implanted with a Jarvik total artificial heart

Maintenance of the body's perfusion by a total artificial heart (TAH) may result in physiological alterations to the circulatory system. Little has been said about modifications to systemic vascular resistances (SVR) during TAH assistance. This paper reports on two patients implanted with a Jarvik - 70 cc TAH, who died after 1 and 3 days, both with an irreversible drop of SVR related to a complete loss of vascular tone but not related to sepsis. Activation of multiple cascades of inflammation, triggered by the extracorporeal circulation (ECC), is maintained during TAH support. Desperately sick patients might not be able to face the vaso-active situations created by the inflammatory response.     

光照黄斑部试验的临床研究─—眼底病患者MPT的改变及其机理的探讨

７９只眼底病患眼的光照黄斑部试验（ＭＰＴ）结果显示：中心性浆液性脉络膜视网膜病变、老年性黄斑变性渗出型和Ｒｉｅｇｅｒ型中心性渗出性脉络膜视网膜病变患眼的光照黄斑恢复时间显著延长，其它黄斑部病变患眼也有不同程度的延长。本文结合眼底荧光血管造影和黄斑视野域值试验对光照黄斑部试验的机理进行了探讨。     

应用低严格度—单引物聚合酶链反应对问号钩体中国参考株的…

Ｇ１、Ｇ２引物是对问号钩体具有特异性引物。分别用Ｇ１或Ｇ２单引物对问号钩体中国参考株进行前４个低严格度循环的ＰＣＲ扩增，扩增带谱显示赖型、犬型、致热型、秋季型、澳洲型、临海型、乌尔夫型、溶血型为一类，而爪哇型、拜伦型、波摩那型、七日热型、巴叶赞型塔拉索夫型、曼耗Ⅱ型是不与以上赖型等血清型本为一类，双曲钩体ａｔｏｃ型及伊利尼细丝体伊利尼型的扩增带谱与问号钩体截然不同。应用苯酚法提取的高纯度钩体ＤＮＡ     

Study on Tongkuaixiao Babu plaster in treating cancer pain

Objective: To explore the efficacy of Tongkuaixiao Babu plaster (TKXBBP) in treating cancer pain.Methods: In the clinical observation, sixty-five patients with moderate or severe cancer pain were randomly divided into two groups: 32 in the treated group (TKXBBP group) and 33 in the control group (Bucinnazine group). The therapeutic effects in relieving pain, improving quality of life (QOL), and the rate of satisfaction the patients felt of the two groups were compared respectively. Results: TKXBBP was effective in treating cancer pain. There wasn’t any statistically significant difference in total effective rate (P>0.05), but the statistical difference was significant in obvious remission rate (P<0.05) between the treated and control group, and the effect on serious pain shown in the treated group was better than that of the control group (P<0. 05). The difference in the initiation time of relieving cancer pain was insignificant (P>0.05), while in the remission period, the treated group showed its treatment was obviously superior to that of the control group (P<0.05). TKXBBP showed better effect in the improvement of QOL (P<0.05) and satisfaction rate, with significant difference between the treated and the control groups (P<0.01).Conclusion: TKXBBPs effect in treating cancer pain was obvious, its application was safe and convenient. It was shown that the external treatment with this kind of Chinese medicine had great advantage in treating cancer pain.
