小剂量氯化汞对小鼠脂质过氧化物的影响

本观察小剂量１ｍｇ／ｋｇ）ＨｇＣｌ２对小鼠肝，脑组织中脂质过氧化物（ＬＰＯ）的影响，发现小剂量ＨｇＣｌ２可使肝组织中ＬＰＯ含量明显增高，与对照组比，差异有显性（Ｐ〈０．０２５），而脑组织中ＬＰＯ含量未见明显影响（Ｐ〉０．０５）。

慢性粒细胞白血病的核型及其预后意义

目的 :分析细胞遗传学在慢性粒细胞白血病 (CGL)的诊断、疗效及其预后中的临床意义。方法 :对 116例采用骨髓细胞直接法和 (或 )短期 ( 2 4h)培养法制备染色体标本 ,采用R显带技术进行核型分析。结果 :在 116例CGL中 ,发现 110例Ph( +) ,在病程各期 (慢性期、加速期、急变期 )均出现 ,占 94.8%。 6例Ph( -) ,占 5 .17%。其中 96例Ph( +)细胞为 10 0 % ,占 87.2 %。 14例Ph( +)细胞为 41.6%～ 93 .1% ,占 12 .7% ,核型呈嵌合状态。 12例除Ph( +)外 ,还出现额外染色体改变 ,占 10 .9%。分别为双Ph ,+8,-Y ,-7及超二倍体 ( >46条 )。绝大部分患者经干扰素、羟基脲治疗后Ph( +)阳性率不变。结论 :染色体核型分析不仅有助于CGL的诊断和鉴别诊断。还是监测病情缓解或复发的重要指标。     

立体定向技术治疗癫痫性精神病的体会

目的：探讨多靶点组合对癫痫性精神病的治疗效果。方法：采用立体定向技术，运用多元化定位和多靶点组合，射频热凝脑内核(团)治疗癫痫性精神病53例。术前、术后均进行总疗效评定量表(GAS)和癫痫的国际疗效评价进行疗效评定。结果：53例中显效37例，进步16例。结论：双侧胼胝体、杏仁核、内侧隔区及单侧红核前区多靶点组合治疗，对癫痫性精神病的治疗有明显作用。     

利培酮治疗与细胞色素P4502D6/C188T酶基因多态性的关联分析

目的　研究利培酮临床效应的个体差异与其代谢酶细胞色素P4 5 0 2D6 (cytochromeP4 5 02D6 ,CYP2D6 )酶基因多态性的相关性。方法　对 88例符合CCMD 3精神分裂症诊断标准的患者和 96例健康对照者作病例 -对照分析。精神分裂症患者给予利培酮治疗 8周 ,用阳性和阴性症状量表 (posi tiveandnegativesymptomscale ,PANSS)评分评价利培酮疗效。采用聚合酶链反应扩增及限制性片段长度多态性 (PCR RFLP)技术对CYP2D6exonⅠ的C188T位点突变进行检测 ,分析利培酮临床效应与其主要代谢酶CYP2D6 /C188T酶基因多态性的相关性。结果　中国上海地区人群的CYP2D6 /C188T突变率(弱代谢型 )为 36 .3% ,病例组和正常对照组间基因型频率总体分布比较无显著差异 (χ2 =1.15 ,df=2 ,P >0 .0 5 ) ,两组间的等位基因频率之间比较也无显著性差异 (χ2 =0 .78,df=1,P >0 .0 5 )。进行性别及有否家族史分组后分析 ,亦无差异存在 ,且CYP2D6 /C188T突变与利培酮临床效应之间并无相关性 (χ2 =1.12 ,df=2 ;χ2 =0 .0 3,df=1,P >0 .0 5 )。结论　未发现中国人CYP2D6 /C188T多态性与利培酮临床效应的个体差异有相关性。

Biologic effects of hyperthermia and radiation on gastric cancer cells (SGC-7901) in vitro. II. Ultrastructural changes of cells

Different characteristic damages of the SGC-7901 gastric adenocarcinoma cells were studied by electron microscopy 1, 36, 72, 96 and 120 hours after heating and radiation in vitro. The visible damages, such as the enlarged mitochondria, increase of lysosomes and perichromatin granules could be shown 1 hour after heating (43 degrees C for 30 min) but no visible damages of the cells were shown until 36 hours following radiation (500 rad). In order to study the ultrastructural changes of the gastric cancer cells in mitosis after heating and radiation, we have used the new method of ultrastructural research in selecting and observing the M cell in vitro and found loosened structure of chromosome and disappearance of microtubules 1 hour following hyperthermia. At the same time, no apparent abnormalities of the mitotic cells were observed after radiation. It is the chief cause of division delay in heat injured cells. However, the chromosomes and microtubules of the new mitotic cells could recover 36 hours after heating (43 degrees C for 30 min). After radiation, the giant cells and abnormal morphologic changes of cells gradually increase and the living cells decrease. Unexpectedly, the division of a few giant cells is observed 72 hours after heating and radiation.
