槲皮素磷酸酯钾对实验性心肌梗塞的影响

iv10～20mg/kg(木解)皮素磷酸酯钾使兔急性心肌梗塞范围明显缩小,ST段明显降低,并能对抗冠脉结扎后引起的血清CPK含量增加及心律失常,这些作用与普萘洛尔相似。但iv40mg/kg后作用不明显。

单向中频电加助透液防治瘢痕增生

为防治瘢痕增生，寻求有效治疗方法，我们采用单向中频电加助透液治疗瘢痕增生患者３３例，痊愈显效率为６４％，总有效率为８８％。结果表明，单向中频电加助透液能增强导入作用，是防治瘢痕增生的有效方法。     

Validation in the sheep of an ultrasound velocity dilution technique for haemodialysis graft flow

BACKGROUND: A simple, rapid, inexpensive method for measuring the flow in a patient's vascular access would permit routine monitoring during haemodialysis, and hence provide information of access graft deterioration sufficiently early to increase the success of minimally invasive remedial procedures. This paper reports the validation of such a method in animals. METHODS: A PTFE graft was implanted in sheep between the carotid artery and the jugular vein. While the sheep was under general anaesthesia and on an haemodialysis circuit, ultrasound velocity in its blood was perturbed by the injection of a 5-10 ml bolus of isotonic NaCl. The pump tubing flow was measured by a transit-time blood flow meter. This flow was combined with the areas of perturbation generated by the injection before and after mixing in the access flow to estimate graft flow. The calculated graft flow was compared to flow measured directly by a transit-time probe on the same carotid artery. RESULTS: Over a 10-fold range, 120-1260 ml/min, graft flow measured by ultrasound velocity dilution agreed well with graft flow measured directly with a scatter of 76 ml/min about the regression line. CONCLUSION: Ultrasound velocity dilution provides a method for measuring flow in the graft accurate enough for clinical evaluation of patients on dialysis.

D4S1647、D6S2414基因座在中国汉族、蒙古族、藏族的遗传多态性

目的 调查D4S1647、D6S2414基因座在中国汉族、蒙古族、藏族群体中的遗传分布规律。方法 采集308份血及唾液标本应用PCR技术，扩增产物用非变性聚丙酰胺凝胶电泳分离，银染显色分析。结果 两位点各群体基因型频率分布均符合Hardy-Weinberg平衡，每一位点等位基因频率分布在各群体间无显著差异；通过对10个汉族家系的遗传模式分析，证实了两位点等位基因传递遵循孟德尔遗传规律。结论 D4S1647、D6S2414基因座在中国汉族，蒙古族，藏族群体均具有高度遗传多态性。     

131例小儿心律失常的临床分析

分析1977～1986年因各种疾病住院伴有心律失常病例131份表明:小儿心律失常的发生、病因、预后等方面与成人相比均有其特点。本组原发疾病共计22种,首位是感染中毒性心肌炎,占50.4％。发作类型以单纯性心律失常为最多见,占42.5％。全部病例采用综合治疗,大多预后良好。
