山莨菪碱对急性脑微循环障碍的防治作用

本实验采用显微摄像技术观察了山莨菪碱（６５４—２）对高分子右旋糖苷（ＨＭＷＤ）诱发的大鼠急性脑微循环紊乱的防治效果。结果显示，６５４—２可明显防止ＨＭＷＤ引起的软脑膜微血管痉挛，血流减慢、淤滞甚至停灌，并能维持严重低血压状态下的脑血流。本发现为临床应用６５４—２预防、抢救缺血性脑血管疾病提供了新的实验依据。     

珊瑚人工骨的研究现况

珊瑚的主要成份是碳酸钙,具有类似人类骨骼的多孔结构。近年来人们将其作为一种新型种植材料进行了不少实验和临床应用研究,证实了珊瑚是一种较为理想的生物活性材料。本文就珊瑚的种类、结构与理化特性,珊瑚的生物学特性,实验研究和临床应用作了综述。

重用仙鹤草治疗腰椎间盘突出症

仙鹤草，味苦、涩，性平。归肺、肝、脾经。功能收敛止血，止痢，杀虫，补虚。《滇南本草》称其可治“腰痛”，《本草纲目拾遗》言其能疗“闪挫”。笔者在临床重用仙鹤草45～60g治疗腰椎间盘突出症多例，疗效较佳，现举例介绍如下。     

兔动静脉短路环法诱导组织工程骨支架材料血管生成的初步研究

Objective To compare the effects of 2 vascular carriers, arteriovenous loop and arteri-ovenous bundle, on inducing angiogenesis in coral scaffold of vascularized tissue-engineered bone in animal models.Methods Thirty-six adult male New Zealand rabbits were randomized into 2 even groups.In group A, an arteriovenous loop (AVL) was formed by microsurgical anastomosis at the proximal ends between the femoral poptiteal artery and vein, and placed in the circular side groove of the coral block (6 mm × 8 mm × 10 mm) .In group B, flow-through vessels bundles of both femoral artery and vein were placed in the side grooves of the coral block.All the implants in 2 groups were wrapped by a micro-porous expand-ed-polytetrafluoroethylene (ePTFE) membrane, and fixed subcutaneously by suturing.Evaluation methods included gross morphological observations, histological examinations, India ink perfusion and vascular casting after 2, 4, 6 weeks.The density of blood vessels was analyzed by the statistical software SPSS 10.0.Results All the corals were encased by newly formed fibrovascular tissues in 2 groups.Ink-stained vessels distributed the surfaces and side grooves, and invaded the interspaces of corals.The degree of vascularization increased over the course of experiment.Blood vessel density demonstrated a significant continuous increase between 2 and 6 weeks after implantation in group A.The mean value of blood vessel density in group A (2 weeks 276.60±4.67, 4 weeks 517.20±10.66, 6 weeks 707.00 ±11.87) was significantly higher than in group B (2 weeks 153.60 ±7.16, 4 weeks 269.40±6.80, 6 weeks 279.20±6.53) (P <0.01).Vascular casting showed that in group A, significant blood vessels sprouted from all areas of the loop, espe-cially at the entrance of the arteriovenous pediele where the small tubes were densely interconnected.In group B, however, no blood vessels sprouted from the arteriovenous bundles and only some small vessels grew from the entrance and exit.Conclusions A vascularized coral model can be constructed by inserting an ar-teriovenous loop or an arteriovenous bundle, useful in vascular bone tissue engineering.The former, however, have stronger abilities to induce angiogenesis than the latter.
