On the termination date, the cultured explants were all examined by Western blot, HE and transmission electron microscope. Our results showed that after 12-days in culture, the cultivation treated with AS-ODN reduced the synthesis of AMBN and had a deformed dental cusp with thinner enamel matrix. Ultrastructure analyses showed that there was hardly any cisternae of the rough endoplasmic reticulum in the ameloblasts at the tip of the cusp of AS-ODN treatedexplants. However, on average the enamel matrix was thinner compared with that in the control group. Furthermore, the collagen fibers in extracellular matrix were found disorganized. These findings seemed to provide a direct experimental evidence that tended to indicate that the arrested AMBN translation in cultured tooth germs might result in the delay of the tooth development.

经用Western蛋白印迹检测表明，所设计的反义核酸对AMBN InRNA具有良好的封闭效果并成功阻断了牙胚对AMBN的表达；在缺乏AMBN情况下，与对照组相比，实验组牙胚在体外可以继续生长发育至钟状晚期，出现成釉细胞和成牙本质细胞的分化，成釉细胞可以分化成为分泌期型成釉细胞，胞浆中缺少合成蛋白质所必需的粗面内质网和高尔基氏体，缺乏溶酶体，表明对蛋白合成和脚的能力降低；实验组牙胚有牙尖形成和基质分泌，但牙尖形态异常，基质形成减少，牙尖周围基质最厚处为O.6卜m，明显薄于对照组的5.spin，基质中胶原纤维粗细不等，排列稀疏， 3 第四军医大学硕士学位论文未见钙化现象，充分证明了AMBN在牙胚发育中参与釉质基质形成和矿化过程，影响胶原纤维和牙本质基质的合成，促进成釉细胞对蛋白质的合成和釉质基质蛋白降解。

Pparent amino acid digestibilities and true amino acid digestibilities of six feedstuffs (barley,cooking blood meal,fermented blood meal,protein hydrolysate mixed feed,heatextruded collagen protein and local fish meal) and their mixed feeds(J1 and J2) were determined with intact and caecectomized cockerels,using Sibbaled "TME" method,and their additivities were also tested.

本研究以去盲肠鸡和正常鸡按Sibbald的&TME&方法分别测定了皮大麦、蒸煮血粉、发酵血粉、水解复合蛋白、热喷胶原蛋白、国产鱼粉及其配合饲料J1和J2的氨基酸表观消化率和真消化率。并对两种试鸡所测上述饲料原料氨基酸的消化率及其可加性作比较。结果表明：（1）6种饲料原料的某些氨基酸表观消化率和真消化率，去盲肠鸡和正常鸡测值间存在显著差异（P＜0.05）。（2）去盲肠鸡内源氨基酸排出量显著高于正常鸡（P＜0.05）。

Methods: A 6-mm unilateral femoral segmental defect was surgically created in 120 Sprague-Dawley rats, internally stabilized with a polyacetyl plate and 6 Kirschner wires, and contaminated with 104 colony-forming units of Staphylococcus aureus.
