高血压家系802人的高血压患病率、知晓率、治疗和控制状况调查

目的了解高血压家系人群高血压患病率、治疗率和控制率特点。方法用整群随机抽样调查的方法调查高血压家系高血压的流行和控制情况，分析比较相关指标的差异。结果家系成员高血压患病率为55．86％，存在危险因素聚集现象。高血压的知晓率、治疗率、控制率分别为79．46％、62．72％、19．64％。结论该地区高血压家系高血压患病率较高，遗传因素是重要原因。虽高血压控制水平较高，但需加强高血压的一级预防。     

阿昔洛韦联合胸腺肽抗乙肝病毒疗效观察

本文报道了阿昔洛韦联合胸腺肽对慢性乙型肝炎抗病毒疗效，阿昔洛韦１０ｇ，胸腺肽１６ｍｇ静滴，每日一次，连续治疗２月，共治疗３３例，治疗结束后，治疗组ＨＢｅＡｇ阴转１６例，阴转率５５１７％，ＨＢＶ ＤＮＡ阴转１８例，阴转率５４５４％。对照组ＨＢｅＡｇ阴转率９５２％（２／２５），ＨＢＶ ＤＶＡ阴转率９０９％（１／２５），两组比较有显著性差异（ｐ＜００１），表明阿昔洛韦联合胸腺肽是一种有效、价廉、使用方便的抗乙型肝炎病毒药物。

增产菊胺酯对雄性小鼠生殖激素的影响

为了探讨增产菊胺酯引起小鼠精了生成障碍的可能机理，本文研究了增产菊胺酯对雄性小鼠卵泡刺激素（ＦＳＨ）、黄体生成素（ＬＨ）及睾酮（Ｔ）的影响。小鼠经口染毒，隔天一次，连续１０次，第３５天处死。检验因清ＦＳＨ、ＬＨ没有明显变化，而睾丸组织睾酮含量出现剂理依赖性降低，高剂量组与对照组比较有显著性差异（Ｐ〈０．０５），结果表明，增产菊胺酯不影响ＦＳＨ、ＬＨ，而影响Ｔ的合成和分泌。这可能是增产菊胺酯对小鼠精     

组织扩张术皮肤胶原的代谢改变

目的：研究常规扩张（ＩＴＥ）和持续快速扩张（ＣＴＥ）对皮肤胶原代谢的影响。方法用白色小家猪制作组织扩张术动物模型，用Ｇｏｒｄｅｌａｄｚｅ法测定血清和扩张组织的羟脯氨酸（ＨＰ）含量，藻酸盐印模材膜片法测量标记区面积；光镜测量真皮厚度。结果：ＩＴＥ组血清ＨＰ含量升高，０．８倍，ＣＴＥ组升高１．２倍，ＩＴＥ和ＣＴＥ组皮肤含量与正常皮肤相同，组织中ＨＰ总量均明显升高，持续扩张皮瓣组（ＣＴＥＦ）术后４ｗｋ皮     

Distribution of glutathione and glutathione-related enzyme systems in mitochondria and cytosol of cultured cerebellar astrocytes and granule cells

The cellular and regional distribution of glutathione (GSH) and GSH-related enzyme systems involved in cellular defense against reactive oxygen species and electrophilic xenobiotics in the nervous system has been extensively studied. However, little is known about the subcellular distribution of GSH systems in brain tissue and cultured neural cells. The present study investigates the distribution of mitochondrial and cytosolic GSH and GSH-related enzymes in cultured cerebellar astrocytes and granule cells, and compares them with levels in the adult rat cerebellum. Cytosolic GSH levels and cytosolic activities of glutathione reductase (GR), glutathione peroxidase (GPx) and glutathione-S-transferase (GST) in astrocytes were 57, 153, 245, and 92% higher than those found in granule cells, respectively. In contrast, granule cells contained significantly higher mitochondrial GSH levels than astrocytes. Granule cells also demonstrated comparable mitochondria/cytosolic concentrations of GSH and GR, GPX and GST activities to those observed in the cerebellar tissue, whereas ratios in astrocytes were markedly lower. Although in vitro treatments with 100 μM ethacrynic acid depleted both cytosolic and mitochondrial GSH in cultured astrocytes and granule cells in a time-dependent fashion, cellular GSH in granule cells was more resistant to the GSH-depleting agent than astrocytes. These results suggest that although GSH and GSH-related enzymes are abundant in cytosolic compartments of astrocytes, mitochondrial pools are relatively small. Since brain mitochondria are sites of significant hydrogen peroxide generation, the mitochondrial localization of GSH and its associated enzymes in neural cells provide important defenses against toxic oxygen species in the nervous system. Differences in subcellular distribution of GSH systems in individual neural cell types may provide a basis for selective cellular and/or subcellular expression of neurotoxicity.

脊髓手术中体感诱发电位监测的临床研究

报告３０例脊髓手术中体感诱发电位（ＳＥＰ）连续监测的临床研究结果。ＳＥＰ记录包括脊髓ＳＥＰ（ＳＳＥＰ）和皮层ＳＥＰ（ＳＣＥＰ）。麻醉药物对ＳＥＰ有一定程度影响，ＳＣＥＰ相对较大。认为，至少术中ＳＥＰ潜伏期延长不超过８％和波幅降低不超过５０％，不会引起术后并发症，超过该范围由于病例较少，尚不能肯定与预后的关系，需进一步探讨。
