Furthermore there are more apoptosis cells in inner root sheath than in outer root sheath. Conclusion When we culture human hair follicle in vitro, Williams E serum-free medium is a suitable choice.This model is a fine model also, which is used for screening drug that may accelerate or inhibit the hair growth.Cryo-section can simplify procedure of paraffin section in histology detection of culture human hair follicle in vitro.We can observe the ultrastructural change of human hair follicle in vitro by transmission electron microscope,which can assist to observe apoptosis cells. The eyepiece micrometer is a simple tool for measuring length of hair follicle in vitro.

在离体培养人头皮毛囊时，Williams E无血清培养基是合适的选择，该模型也是筛选促进或抑制毛发生长药物的良好模型；离体培养毛囊组织学检测用冰冻切片可以简化步骤；透射电镜可以用来观察离体培养的毛囊的形态和超微结构的变化，也可以用来协助观察细胞凋亡的状况。

XD-2003 strap machine is changed from XD-2002 machine which has a cast aluminium on the bed,making the screw,screwtube and speed reducer keeping concentric.the V-model manger on the bed is lower than the flat on which the speed reducer is fixed,the components are finished machining by machine tool.guaranteeing perpendicularity, degree of balance.speed reducer,screw and screwtube is fixed on the base,and the screwtube is in the mini-manger,then ensuring axis keeping concentric with sheath,screwtube feed opening has a chromium hard-wearing sheath,which can improve the lifetime of the screw and screwtube to threefold or to fourfold.

XD-2003 型塑料打包带机组，是在XD-2002型机组的机座上安装了一个铸铁机座，使螺杆，螺筒和减速机保持同心，座上的V型槽比安装减速机的平面低，其部件都是经过机床精加工完成的，保证了垂直度和平衡度。减速机和螺杆、螺筒置于底座上，且螺筒卡在微型槽内。确保轴与套保持同心，螺筒下料口处设有高铬耐磨衬套，这样可使螺杆、螺筒的寿命提高3-4倍。

With conventional PCR primer pair XBFF/R,the same 352bp bands appeared by amplifying all the DNA samples from the eight races,and no bands appeared by amplifying all the DNA samples from the 9 plant pathogen species(Cucumber powdery mildew,wheat yellow rust,wheat leaf rust,wheat stem rust,wheat scab,wheat sheath blight,wheat loose smut,maize sheath blight and maize head smut)and control.

3用常规PCR和实时荧光PCR两种方法对温室接种的小麦白粉病进行了检测，并在时间上与自然显症的观察进行了比较，结果表明：在温室条件下，小麦白粉病菌在接种后第5d时开始出现小麦白粉病病斑，而利用常规PCR引物XBFF/R可在接种第3d检测到小麦白粉病菌，比自然显症观察能够提前了2d检测到白粉病菌；实时荧光PCR法可在接种后1d即能检测到小麦白粉病菌，比自然显症观察能够提前了4d检测到白粉病菌，这可为白粉菌的预测或预警检测提供依据，更可为白粉病在流行前制定防治决策赢得宝贵时间。4。
