136例阿片类药物依赖者SCL-90的评定结果分析

本文应用ＳＣＬ－９０对１３６例阿片类药物依赖者进行测评，并与正常人进行对照分析。结果显示研究组总分及各因子分与正常组相比差异有显著性。说明毒品滥用人群心理问题严重，突出表现在焦虑、抑郁等几方面，提示戒毒治疗仅进行临床脱毒治疗是远远不够的，还必须重视这一人群的心理问题，并加以矫正，才能提高工作成效

Benign intracranial hypertension and recombinant growth hormone therapy in Australia and New Zealand

Benign intracranial hypertension (BIH) is reported in three children from Australia and one from New Zealand, who were being treated with recombinant human growth hormone (rhGH). Three males and one female, aged between 10.5 and 14.2 y, developed intracranial hypertension within 2 weeks to 3 months of starting treatment. A national database, OZGROW, has been prospectively collecting data on all 3332 children treated with rhGH in Australia and New Zealand from January 1986 to 1996. The incidence of BIH in children treated with growth hormone (GH) is small, 1.2 per 1000 cases overall, but appears to be greater with biochemical GHD (<10IUml ^-1), i.e. 6.5/1000 (3 in 465 cases), relative risk 18.4, 95% confidence interval 1.9-176.1, than in all other children on the database. The incidence in patients with Turner's syndrome was 2.3/1000 (1 in 428 cases). No cases in patients with partial GHD (10–20 IUml ^-1) or chronic renal failure were identified. Possible causative mechanisms are discussed. The authors'practice is now to start GH replacement at less than the usual recommended dose of 14IUm-² week^-1 in those children considered to be at high risk of developing BIH. Ophthalmological evaluation is recommended for children before and during the first few months following commencement of rhGH therapy and is mandatory in the event of peripheral or facial oedema, persistent headaches, vomiting or visual symptoms. The absence of papilledema does not exclude the diagnosis.     

膜荚黄芪毛状根中异黄酮成分的反相高效液相色谱分析

对膜荚黄芪毛状根中6种异黄酮成分进行了反相高效液相色谱法测定。色谱柱为NucleosilC₁₈柱,流动相为甲醇—水(3∶2和3∶1,v/v),检测波长为254nm和280nm。6种异黄酮成分为:10-羟基-3,9-二甲氧基紫檀烷,(3R)8,2’-二羟基-7,4’-二甲氧基异黄烷,芒柄花素(7-羟基-4’-甲氧基异黄酮),8,3’-二羟基-7,4’-二甲氧基异黄酮,2’-羟基-3’,4’-二甲氧基异黄烷-7-O-葡萄吡喃糖甙,毛蕊异黄酮(7,3’-二羟基-4’-甲氧基异黄酮)。异黄酮浓度在2.5～12.5μg范围内与峰面积有良好的线性关系;加样回收率为96.47%～103.33%;精密度试验相对标准偏差为2.57%～6.52%;测得黄芪毛状根中6种异黄酮成分的含量在0.0005%～0.0065%之间。     

Quantitative analysis of the tomographic technetium-99m MIBI (99mTc-MIBI) myocardial bullseye display: Application to diagnosis of coronary artery disease

Summary In this study, the^99mTc-MIBI myocardial bullseye display of 31 healthy persons and 34 patients with myocardial ischemia and 17 patients with myocardial infarction were analyzed quantitatively, and compared with the results of myocardial tomography analysis and qualitative bullseye analysis. The sensitivities of the three methods were 88.2%, 91.2% and 94.1% respectively (P>0.05), and the specificities were 93.5%, 83, 9% and 83.9% respectively (P<0.05). On the other hand, the quantitative analysis obviously outperformed the other two methods in the detection of ischemic segments of myocardhum near infarction zone (P<0.01). The quantitative analysis of^99mTc-MLBI myocardial bullseye (quantitative bullseye) was an objective, specific and sensitive method for diagnosis of coronary artery disease.     

实验性糖尿病大鼠肝,肾,心,脑脂肪酸代谢的动态变化

报道对链脲佐菌素（STZ）诱导的实验性糖尿病大鼠几种重要脏器（肝、肾、心、脑）卵磷脂、脑磷脂中脂肪酸构成的变化。不饱和脂肪酸变化的模式（C18：2n-6，C20：3n-6，C22：5n-3，C22：6n-3增加，C20：4n-6降低）基本相同，改变的先后顺序是肝→心、肾→脑。     

氩激光治疗中心性浆液性脉络膜视网膜病变

应用氩绿激光光凝治疗中心性浆液性脉络膜视网膜病变36例41只眼。结果视力≥1.0者从术前的17.1％增加到术后的63.5％,而视力≤0.6者从术前的61％降低到术后14.6％,术后1周至1月,多数患眼视网膜下液全部吸收,部分患眼中心凹反光重显。结果还显示术后视力与病程长短有关,但术后视力与渗漏点的方位、渗漏点中心凹距离以及神经上皮脱离的大小无关。     

粮谷尘致肺损害的实验研究

粮谷尘为混合性粉尘，含游离ＳｉＯ２９．７７％，分离培养出普通高温放线菌。染尘动物肺脏早期病变主要为小灶性肺泡炎、灶性间质性肺炎、异物肉芽肿等，大、中支气管壁脱颗粒肥大细胞增多。９０ｄ以后，上述病变明显减少，但逐渐出现少数小的细胞结节，间质轻度纤维组织增生、支气管慢性炎症和小叶中央型肺气肿样病变，观察１ａ（年）未见明显纤维化。
