It was typically indirect effect that the following variations induced in the progenies of endosperms implanted by heavy ion beams were discovered. 1 In comparison with control, there were very high differences in biological trait, anti-oxidation enzyme activity, MDA content and protein content, chromosome aberration rate and micro-nucleus rate in M1 generation. 2 Shorter stem variants and purple stem mutants were analyzed by RAPD and AFLP. The analytic results showed that the sequences of their DNA were changed, so those variations were not physiological damage only. And there were differences among M2 generation plants of the same sort of variants or mutants, it was indicated that M2 generation may be in disjunction.

M1代的生物学性状、幼苗的抗氧化酶活性、MDA含量、蛋白质含量和染色体畸变率及微核率等发生了较大的变化。2）对其矮杆变异株和紫色茎杆突变体（M2）做RAPD和AFLP分子鉴定等研究，结果显示了矮杆变异体和紫色茎杆突变体的DNA序列发生了改变，而非仅仅产生生理损伤；同一种变异体或突变体，在M2代单株间也存在着明显的差异，表明它们可能还处于分离状态。

Abstract］ objective to discuss the clinical meaning of the treatment of tibial plateau fracture by mipo and operation method.methods 34 cases of tibial plateau fracture with schatzker typeⅰ～ⅴ were treated by mipo during march 2005 to june 2007,then followed-up all the cases.results using mipo to treat the tibial plateau fracture in reducing bleeding and operating time,all cases had no tresis vulnus infection and necrosis,no fracture disunion,no loosening and breaking of internal fixations,etc.the knees function regained well.conclusion treating tibial plateau fractures with mipo has little obstructe in environment of fracture healing through minimally invasive,has fortes of minimally invasive,firm of internal fixations,low rate of infection,high rate of fracture healing,can reduce the complications,fit principle of biologic fixation.

目的 讨论应用微创接骨板固定术在治疗胫骨平台骨折中的临床意义及手术方法。方法运用mipo技术治疗2005年3月～2007年6月34例schatzkerⅰ～ⅴ型胫骨平台骨折，并对其进行随访观察。结果运用mipo技术治疗胫骨平台骨折，手术时间短，术中出血量少，没有发生伤口感染坏死、骨折不愈合和内固定松动、断裂等并发症，术后患者膝关节功能恢复良好。结论 mipo在治疗胫骨平台骨折时以微创来提供尽可能少受干扰的骨折愈合环境，具有创伤小、固定确实、感染率低、骨折愈合率高等优点，减少了并发症的发生，符合生物学固定的原理。
