电针改善硬膜外吗啡用于术后镇痛所引起的免疫抑制

为观察硬膜外吗啡和电针对术后患者免疫功能的影响，检测自然杀伤细胞（ＮＫｃｅｌｌ）活性和ＰＨＡ诱导白细胞介素２（ＩＬ－２）水平在单纯胆囊切除术患者术前和术后第１、３、７天的动态变化情况。结果吗啡组ＮＫ活性在术后第１、３、７天抑制，手术组仅在术后第１、３天出现抑制，而抑制率低于同天的吗啡组，电针可拮抗吗啡引起的ＮＫ活性抑制加深状况。在术后第１天，手术组和吗啡组ＩＬ－２水平均下降，吗啡＋电针组无明显变化，术后第７天吗啡＋电针组ＩＬ－２升高接近正常人水平。表明电针能改善硬膜外吗啡引起的免疫抑制，促进术后机体的恢复。硬膜外吗啡结合电针是值得推荐的术后镇痛方法。     

大鼠心脏不同部位α1肾上腺素受体亚型的分布

用放射配体结合实验研究大鼠心脏不同部位α１肾上腺素受体（α１受体）及其亚型的分布。结果表明，大鼠心脏左、右心房及心室中α１受体的密度基本一致；不同部位的α１受体均包含α１Ａ与α１Ｂ两种亚型，左心房及心宝α１Ａ亚型占全部α１受体的３０％左右，α１Ｂ亚型占７０％左右；而在右心房中α１Ａ亚型的比例为１４％左右，显著低于左心房与心室。说明大鼠心脏不同部位的α１受体分布相同，但其亚型分布具有显著的区别。     

Sensory information—The major factor of ontogeny

On the basis of their own data the authors postulate that the increase in sensory input during early ontogeny results in a delay in the development of the sensory systems formed earlier. In connection with this, the sensory basis of behavioral patterns becomes ineffective, causing their reorganization and the appearance of new forms of behavior. Limitation of sensory input during the critical periods of development stimulates the accelerated manifestation of behavioral patterns. However, this acceleration also has long-lasting negative effects— alterations in the processes of learning and memory in adult animals.

Effects of synthetic C-terminal fragment of interferon-2α on Daudi cells

Synthetic fragment of human interferon-2α (124th–138th amino acid residue, laboratory code 2438) inhibits the growth of B lymphocytes (Daudi cell line) in a dose-dependent manner. Radiolabeled peptide 2438 binds to specific receptors on the cell surface and competes with interferon-2α for the common binding sites.

免疫抑制剂SIIA9268A的研究.Ⅰ.发酵、分离及理化性质

在用含ｒａｐａｍｙｃｉｎ结合蛋白基因（ＲＢＰ）的啤酒酵母ＲＳ１８８Ｎ及其变株ＲＳ１８８Ｎ△ｒｂｐ：：：ＬＥＵ筛选免疫抑制剂的过程中，得到活性菌株Ｎｏ．ＳＩＩＡ９２６８（鉴定为吸水链霉菌东湖变种）。应用硅胶柱层析和制备ＴＬＣ等方法从其发酵液中分离出活性化合物ＳＩＡ９２６８Ａ。经理化性质鉴定与ｒａｐａｍｙｃｉｎ同质。     

CT对眼球异物的诊断及定位

本文比较了11例眼球异物CT与X线影像，并经手术摘出异物证实，CT眼球异物检出及定位准确性均优于X线，尤其对球壁异物的定位，而且能显示断层眼球壁轮廓，具有直观效果，CT异物影像比异物明显扩大，应警惕CT伪影可能使球壁异物定位发生误差，CT目前尚不能完全取代眼球异物常规X线检查。

小儿腭裂修复术后麻醉恢复期的观察与护理

腭裂是口腔颌面外科常见的先天畸形，手术修复是唯一有效的治疗方法，术后护理直接关系到手术的成功与否，特别是全身麻醉恢复期，患儿易出现各种意外，故应加强护理，采取有效预防措施，以确保麻醉恢复期平稳度过，保证手术成功。我科2001年3月-2006年4月收治腭裂患儿396例，全部安全度过麻醉恢复期。现将护理体会总结如下。
