After treatment of benzamide which is an inhibitor of poly polymerase,β-galactosidase activity assays and PCR analysis were performed to test the deletion of LacZ gene and c-Ha-T24ras gene. The results showed that:(1)LacZ gene was deleted from both A13.4-NIH3T3 cells and B12.7-NIH3T3 cells, but neigher from A13.4-HeLa cells nor B12.7-HeLa cells. So it is possible that there is cell line specificity in gene deletion induced by BA.(2) In A13.4-NIH3T3 cells, LacZ gene and c-Ha-T24ras gene were completely deleted at the same time.(3) The transcription activity of exgenous DNA fragment may have same effect on its sensitivity to the deletion induced by BA.

The structure and stability of all possible isomers of C50X(X=SiH2, PH, S) were investigated by ab initio HF/3-21G calculations. The calculation results indicate that the preferred position for cycloaddition of SiH2, PH, and S on C50 is consistent, i.e. on the C3-C4 and C4-C4 sites of C50, and the resultant most stable cycloaddition isomers are [5,6]-closed and [5,5]-closed structures. The main driving force governing the stability of the C50X(X=SiH2, PH, S) isomers is the strain, or the conjugative effect, or the combination of strain and conjugative effect, depending on the addition positions and the types of the attacked C-C bonds.

用从头算HF/3-21G方法研究了C50的环加成衍生物C50X(X=SiH2， PH， S)所有可能的异构体的结构与稳定性，计算结果表明，SiH2基团、PH基团与S原子在C50上环加成的优先加成位置相同，都为C3-C4类键和C4-C4类键，并且相应形成[5，6]-闭环和[5，5]-闭环结构的最稳定异构体；决定C50X(X=SiH2，PH，S)各异构体稳定性的主要因素，因加成位置以及发生加成反应的C-C键的单双键类型的不同，可能是张力、共轭效应或者二者的共同作用。
