The genes of hammerhead ribozymes targeting against two and three sites on negative strand of potato spindle tuber viroid were designed, synthesized and cloned according to the action manner of hammerhead ribozyme.

根据锤头型核酶的作用模式，设计、合成并克隆了特异切割马铃薯纺锤形块茎类病毒负链RNA不同区域位点的双价和三价锤头型核酶基因。通过体外转录，将PSTVd负链RNA分别与双价和三价核酶混合，37℃温育 2h。

Hammer-flake grinder uses the energy that the high-speed rotary, hammer-flake schleps to hit the raw materials, and makes them luther grinde when gear plate and sieve plate hit together.

锤片粉碎机利用高速旋转的锤片所携带的能两撞击物料，使物料破碎并能高速与齿板碰撞后进一步破碎，此过程反复进行，直到物料小于筛板孔径后穿过筛板排出机外。

In conclusion, our results suggest the possibility of the hammerhead ribozymes RzA and RzC to be used for the gene therapy of HBV infection.

结果指出，锤头状核酶RzA和RzC能介导细胞内抑制HBV的复制和表达，以及RzC通过抑制HepG2.2.15细胞中HBV的复制显示抗病毒感染的能力。表明锤头状核酶有可能作为HBV基因治疗的一种手段。
