Recently, it has been found that some inducers such as retinoids acid and yeast containing Se can prevent and reverse PLGC of rats to some extent. But all of these data are obtained from animal experiments, information of clinical research has not been reported. Natural β-carotin and folic acid can reverse dysplasia and intestinal metaplasia of gastric mucosa to some extent, but these effects are required to be further investigated.

晚近发现维甲酸类诱导分化剂及硒酵母对大鼠PLGC演变至胃癌有一定阻抑预防和逆转治疗作用，但均仍停留在动物实验阶段而未用之于临床；天然β-胡萝卜素和叶酸干预治疗后能一定程度地逆转胃粘膜异型增生和肠化生，值得进一步深入。

Objective: To study osteogenic capability of rabbit bone marrow stromal cells and biological characteristical identification in vitro in order to explore the appropriate methods of osteoblast culture in vitro and to select an idea source of seed cells for bone tissue engineer.

目的：研究兔骨髓基质细胞在体外培养条件下的成骨能力及生物学特性，探讨简便易行的成骨细胞体外培养方法，为组织工程选择理想的种子细胞来源。方法：取新西兰白兔骨髓液经离心后得骨髓单个核细胞，以1× 106／ml的细胞浓度进行培养，经传代培养，选择条件培养液培养(1640完全培养液中加入地塞米松10-8Smol／l，β-甘油磷酸钠10mmol／l，VitC 50μg／ml)作为骨髓基质细胞增殖和成骨的调节因子，通过倒置显微镜、HE染色、扫描电镜、碱磷酸酶(alkaline phosphatase，ALP)测定、Ⅰ型胶原免疫组化染色和四环素荧光钙染色等手段对获得的细胞进行生物学特性研究。

Well," he said to me, cheerily, when we met in the first laboratory hour the semester,"we're going to see cells this time, aren't we?""

The results indicated that LVPO might play a role in respiratory responses to CO〓, and also suggested that LVPO might participate in the mechanism of central chemoreception.

实验表明损毁LVPO后能明显地减弱呼吸中枢对CO〓的反应性，提示LVPO在吸入CO〓所引起的兴奋反应中起着一定的作用，为LVPO参与中枢化学感受性机制提供了另一佐证
