Graves病患者血清及头发微量元素测定分析：附24例报告

测定了３０例健康对照及２４例Ｇｒａｖｅｓ病患者血清及头发锌、硒、钒、锂及锗的含量。结果Ｇｒａｖｅｓ病患者血清及头发５种微量元素含量均较对照组低，有统计学差异。血清与头发锌、钒、锗含量呈正相关关系。经抗甲状腺药物治疗后，血清及头发５种微量元素均较治疗前上升，有统计学差异。     

经皮肺动脉瓣狭窄球囊导管扩张术的方法和疗效评价(附7例报告)

应用经皮球囊导管扩张术治疗先天性肺动脉瓣狭窄7例(男3例,女4例,年龄5～32岁),均获成功。球囊直径较肺动脉瓣环大30～50％。扩张前后右室收缩压分别为65mmHg和46mmHg,下降19mmHg(P<0.05);扩张前后跨瓣压力阶差分别为45mmHg和21mmHg,降低24mmHg(P<0.05)。术后平均随访36个月,患者症状改善,活动耐受性增加,杂音减轻,提示近期疗效良好。

A803饮水消毒效果

A803是巯基吡啶-N-氧化钠盐的简称,为饮水消毒剂,用本品进行实验室、现场饮水消毒及致突变试验。试验微生物有:大肠菌群、E·coli-f~2噬菌体。 结果表明:A803用于饮水消毒,实验室最小有效剂量为17.5mg/L;pH值、温度对消毒效果无明显影响。现场实验选用多种水源,用A803 23.75～30mg/L,SM-92号混凝剂8mg/L,消毒30分钟可使细菌总数由5.5～8.4×10~3个/mL下降到0,大肠菌群由23800个/mL下降到<3。致突变实验结果表明TA98、TA100两个菌株的回变菌落数与阴性对照相近,从饮水消毒角度是安全的。     

An experimental study of intravascular stent in abdominal aorta of atherosclerotic miniature pigs.

To study the effects of nitinol alloy stent in the treatment of atherosclerotic arterial stenosis, eight miniature pigs were subject to abdominal aortic balloon denudation and high-fatty food. Then 8 nitinol alloy stents were implanted into each abdominal aortas of pigs. The pigs were equally divided into two groups. One group was given captopril (3 mg / kg / d). All animals were sacrified) for pathological examination 6 to 10 months after stent implantation. The degree of arterial intima proliferation in the areas of stent implantation not significantly different from that of areas of balloon denudation alone; the atherosclerotic lesions were found at the arterial surface of stent implantation sites. The intima layer was rich in smooth muscle cells, with atherosclerotic plaque formed around the stent wire. On the other hand, significant decrease in arterial intima proliferation was found in group Ⅱ with no atherosclerotic plaque. The arterial stenosis resulting from atherosclerotic lesion could not be
