Methods: The telomerase activity in breast cancer cells and MRC-5 cell line were detected semi-quantitively by TRAP-ELISA assay. Virus proliferation as- say and cell viability assay were used to evaluate the proliferation and cytolysis selectivity of CNHK300, and the results were compared with those of wtAd5. The breast cancer cells were treated with CNHK300 combining paclitaxel to evaluate the killing effect of the combined regimen.

用TRAP-ELISA方法检测乳腺癌细胞株(MDA-MB-453、SK-BR-3)和正常成纤维细胞株MRC-5的端粒酶活性；进行病毒增殖实验和细胞生长抑制实验，并与野生型腺病毒wtAd5进行对比，验证CNHK300选择性复制和选择性杀伤能力；用细胞生长抑制实验进一步考察CNHK300与化疗药物紫杉醇联合应用对乳腺癌细胞的杀伤作用；用Western blot检测腺病毒E1A在细胞中的表达。

Because different cell lines may show various levels of susceptibility to adenovirus infection and virus production, non-selectively replicating wtAd5 was used to be a comparison with the tested conditionally replicating adenovirus CNHK500.ONYX-015, the first replication-competent adenovirus entered into clinical trials was also used to be a comparison. We used virus proliferation assay, cell viability assay and western blot to evaluate the proliferation and cytolysis selectivity of CNHK500. Results demonstrated that the CNHK500 virus proliferation multiples in breast cancer cell lines after 48 hours is similar to that of wtAd5, ONYX-015 virus proliferation ability is less than that of CNHK500 in cancer cells.

然后，通过与ONYX-015（E1B 55 KD a蛋白缺失的2型和5型嵌和型腺病毒，美国ONYX生化制药公司研制）、wtAd5进行对比，利用病毒增殖实验和细胞生长抑制实验，验证了CNHK500选择性增殖能力和肿瘤特异性杀伤作用；利用Western Blot检测CNHK500腺病毒E1A和E1B在乳腺癌细胞和正常成纤维细胞中的表达差异，揭示了腺病毒肿瘤靶向性的机制；利用携带绿色荧光蛋白的CNHK500-EGFP感染乳腺癌细胞株和正常成纤维细胞株，直观地观察其感染乳腺癌细胞的能力和在乳腺癌细胞中的增殖过程。

Now the research on HPL focus on dicotyledon, and the research on HPL of monocotyledon still havent been reported. In this paper, the research on cloning of rice HPL and enzyme activity assay were carried out and several result were obtained.1. Enzyme activity assay of rice HPLBased on the method of measure HPL Enzyme activity in other plants, the means on preparation of hydroperoxides and measurement rice HPL activity were set up. The 9-HPL arid 13-HPL activity of several rice varieties with different storability and different dormancy were tested.
