In addition to Fe+(54Fe+, 56Fe+, 57Fe+), other fragment ions were detected in bacteriogenic pyrites, such as 27 Al+, Si+(28Si+, 29Si+, 30Si+), 40Ca+, Cu+(63Cu+, 65Cu+), Zn+(64Zn+, 66Zn+, 67Zn+, 68Zn+), Ni+(58Ni+, 60Ni+, 62Ni+), and C3H7+.

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.

用聚ADP核糖聚合酶的NAD位点抑制剂苯甲酰胺分别处理四种转化细胞后，检测细胞中整合的外源LacZ基因与c-Ha-T24ras基因的删除情况，结果如下：BA诱导的基因删除可发生于NIH3T3转化细胞系，但不能发生于HeLa转化细胞系；位于同一外源表达载体上的LacZ基因与c-Ha-T24ras基因的删除过程是同步的；外源整合DNA片段的转录强度可能直接影响其被BA诱导删除的敏感性。

Replacement of one benzimidazole fragment with benzothiazole or benzoxazole and optimization of the structure to create the new frame of the compounds were also carried out with the exception to find more potent compounds.

The total RNA was abstracted from the larvae of Boophilus microplus, and a 1982bp Bm86 gene was amplified by RT-PCR. The target gene was subcloned into T vector. The sequencing showed that the nucleotide sequence of the cloned Bm86 gene shared 97.4% homology with the data published in and this fragment contained the complete open reading frame of Bm86 gene.
