objective:to investigate the expression and significance of rb in the occurrence, development and regression of infantile hemangiomas.methods:the expression of rb was examined in the proliferative stage and catagen of human hemangiomas and normal skin tissues by using immunohistochemical technique.immunohistochemical technique for factorⅷ-related antigen was used to prove that the cells which expressed rb were endothelium.image analysis system was applied to measure the expression level of rb at different stages of hemangiomas and in normal skin tissues.results:the expression of rb was significantly lower in proliferating hemangiomas than that in involuting hemangomas(p.05).conclusion:rb might play an important role in the regression of human hemangioma endothelial cells and anti-angiogenesis.

目的：探讨rb蛋白在血管瘤发生、发展及退化过程中的表达状况及其意义。方法：采用免疫组织化学方法检测人皮肤血管瘤增生期、退化期及正常皮肤组织中rb的表达水平，并结合第ⅷ因子相关抗原的免疫组织化学染色证实表达rb的细胞是血管内皮细胞。利用计算机图像分析技术测量不同时期血管瘤组织和正常皮肤组织rb表达的积分光密度和面积。结果：增生期血管瘤内皮细胞rb表达水平低于退化期，差异有显著性（p.05），退化期血管瘤内皮细胞rb表达水平与正常皮肤组织相比，差异有显著性（p.05）。结论：rb通过抑制血管瘤内皮细胞增殖和血管生成而在血管瘤的退化过程中起重要作用。

Shenyang Research Institute of Chemical Industry, Shenyang 110021, China Abstract: Spectrophotometric analysis showed that the peak absorbance for food dye of Allura Red and biological dye of Ponceau-G occurred at 501 and 510 nm. In sunlight after 2, 4, 6, 8, 10 hours, the decomposition rates of Allura Red and Ponceau G were between 2.4 to 5.8% and 3.4 to 10.8%, so they are stable in sunlight. The recovery rates on cottons and glasses were very high, so they are easily recoveried from targets. Further studies showed that the recovery rates of two dyes on the leaves of wheat, cabbage, cucumber and tomato were different, so it need previously determine the recovery rate of tracer on the target crop to adjust the result. Field experiment showed it was easy to measure the pesticide spray distribution of high volume spay and low volume spray to use Allura Red and Ponceau-G as tracers.

沈阳化工研究院，沈阳 110021 摘要：光谱分析表明，食品染色剂诱惑红和生物染色剂丽春红-G的最大吸收波长分别为501 nm和510 nm ；在连续2、4、6、8、10 h阳光照射下，分解率分别在2.4%~5.8%和3.4%~10.8%之间，见光稳定性良好；两种染色剂在棉花叶片和玻璃片上的洗脱回收率都很高，说明易于从靶标上洗脱下来；进一步测定表明，两种染色剂在小麦、甘蓝、黄瓜、番茄叶片上的洗脱回收率各不相同，所以对准备进行测试的作物应先做一次洗脱回收率试验，用以校正测试结果；田间应用表明，用两种染色剂做示踪剂，可以方便地测定常量喷雾和低容量喷雾过程中农药在麦田的沉积分布情况。

Polymorphism of Rb (intron 17) is relatively stable and rarely mutates, but poly morphism of Rb gene (intron 20) locus is characteristic in the old people. The r elation between Rb gene (intron 20) and ageing needs further study.

老年组Rb基因20内含子的位点多态性与青年组比较差异有显著性意义，是否该位点遗传标记与细胞的衰老有一定的相关性，值得进一步研究。
