The results showed that the growth of root tips in liquid medium was better than that in agar-solidified medium and solid-liquid two phase medium, for that increasing agar concentrations in medium will reduce the root growth; darkness was beneficial for Fraxinus mandshurica root tip culture in vitro; as the carbon sources, sucrose was better than glucose and maltose as the carbon ...

结果表明，不添加琼脂的液体培养基对根尖的生长较添加琼脂的固体培养基和固—液培养基好，原因是增加琼脂的量会抑制根的生长；暗培养比光培养更有利于水曲柳离体根尖的培养；蔗糖作为碳源的效果较果糖和麦芽糖好，其中以3%的蔗糖对离体根尖的生长效果最好。

Results ⑴ The cell proliferation was inhibited by TET. It showed thatdivision index and cell number during G0-G1 were decreased, while S and G2-M phases were lengthened with dosage and time dependency in dosages of TET from 2mg/L to 8mg/L; besides, oval-shap cells, karyopyknosis and fragmentation were observed under light microscope. The inhibitory effect in T2 group was statistically similar to that in triamcinolone.

结果⑴ TET在2mg/L~8mg/L之间呈剂量及时间依赖性地抑制瘢痕成纤维细胞的增殖，使生长曲线不同程度的压低、分裂指数降低、G0-G1期细胞数减少、G2-M期增多、S期与G2-M期延长，光镜下见细胞突起变短，细胞由梭形变成椭圆形，核固缩、碎裂。P.C的改变近似于T2组(4mg/L TET)。

Importantly, depletion of ARMS facilitated UVB-induced apoptosis in melanoma cells through inactivation of MEK/ERK pathway, which is not constitutively activated in most cases of acral lentiginous melanoma, the melanoma subtype found mostly in Asians.

更重要的是，减少ARMS在黑色素细胞癌细胞的表现，会促进紫外线B光诱发之细胞凋亡，其作用机转是透过MEK/ERK传递路径之抑制，此路径在多数亚洲人常见的肢端小痣型黑色素细胞癌并无自身活化之现象。

The results show that temperature does not have a significant impact on derivatization reaction; the derivatives are rapid degraded in sun light; the derivatization reaction is inhibited when the derivatization reagent is at high concentration; the reaction to produce the fluorescent derivatives is finished in 30 min, and the derivatives are stable for about 8 h at normal temperature and lightless.
