髓形成

ABSTRACT］ Objective To observe the efficacy and side effects of combined therapy with alltrans retinoic acid, arsenic trioxide (As2O3) and chemotherapeutics for newly diagnosed acute promyelocytic leukemia.

急性早幼粒细胞白血病是急性髓系白血病中的一种独特类型(M3型)，以特异的染色体易位t(15，17)(q22，q21)为特征，形成PMLRARa融合基因，该融合基因是APL发病的分子基础和分子标志。

In DM group, decreasing of density of axoplasm, deposition of fat droplets, swelling and vacuolization of mitochondria and separation or disintegration in lamellar of myelin sheath of the sciatic nerve fiber could be observed, which could be partially improved by EA and KBK.

电镜形态学分析见造模两个月的糖尿病大鼠坐骨神经髓鞘板层有分离现象，线粒体嵴紊乱，有的线粒体嵴完全消失形成空泡线粒体，轴浆内有大量脂肪颗粒沉积；经电针和渴痹康治疗后能减轻这些病理改变。4。无论是电针治疗还是渴痹康治疗均无明显降血糖作用。

Trama The inner tissue of the gills in basidiomycete fungi that is made up of loosely packed hyphae.

In practice, this is because just before the out of teeth, root is not fully formed, the pulp cavity and apical foramen are large, thin apical cementum caused.

实际上，这是因为之前出牙，根尚未完全形成，牙髓腔和根尖孔大，薄根尖牙骨质造成的。

The expression level of metabolitic enzyme (CYP1A1, CYP1B1) and its correlation with cell differentiation /apoptosis were studied as well. The influence of resveratrol in cell cycle was determined with FCM. Results 1 Resveratrol not only suppresses the growth of medulloblastoma cells in a dose and time related fashion but also induces cell differentiation and apoptosis. Resveratrol promotes differention of UW228-1,-2 cells to forward glia, UW228-3 and Med-3 cells to neuron. A treatment of resveratrol in the concentration of 100μM for 48hrs comit most of cells die of apoptosis. 2 Among the four cell lines Fas and Caspase-3 were constantly expessed, whereas FasL was absent irrespective to the drug treatment. 3 ICC, RT-PCR, Western-blot hybridization and EROD enzymatic activity assay demonstrated that expression of CYP1A1 is different after treatment with resveratrol in four cell lines, up-regulated in three UW228 cell lines in a dose dependent manner but down-regulated in Med-3 cells. Suppressive effect of resveratrol on CYP1B1 expression is the same among four medulloblatoma cell lines. 4 Cell cycle distribution of UW228-3 was greatly changed after treatment.

结果：1、白藜芦醇以时间和剂量依赖性方式抑制髓母细胞瘤细胞生长，同时促进细胞的分化和凋亡：白藜芦醇促使UW228-1、-2靶细胞向神经胶质细胞方向成熟分化，UW228-3、Med-3细胞向神经元细胞方向成熟分化，以100μM作用48小时效果显著；2、四个细胞系均有Fas和Caspase-3表达，但无Fas-L基因表达和蛋白活性产生，因此难以形成Fas相关性死亡通路；3、白藜芦醇处理前后CYP1A1基因的表达在各细胞系略有不同：UW228-1，-2，-3三个细胞系白藜芦醇以剂量相关性方式上调CYP1A1的表达，而Med-3细胞系，白藜芦醇却抑制CYP1A1的表达；四个细胞系在白藜芦醇处理后CYP1B1的表达均受到抑制；4、UW228-3细胞系经白藜芦醇作用后细胞周期有较大改变，表现在G0/G1期在整个细胞周期中所占的比例增加，而其它时期则相应减少。

In immature permanent teeth, devitalization and root canal treatment are not advisable until full apex formation and closure have occurred.

在未成熟恒牙，根尖形成和闭合之前，不宜行失活及根管治疗术，而应行去髓术并氢氧化钙安抚。
