Ames test of nano-β-tricalcium phosphate /collagen artificial bone;

Methods Produce the nano-hydroxyapatite artificial bone and it s diffusion and test thediffusion through Ames test.

Study on the mutagenicity of phenolic compounds by the Ames test;

Study on mutagenicity of sulfur mustard by Ames test;

Evaluation of arginine esterase from Agkistrodon halys ussuriensis venom for gene mutation in Ames test;

Study on mutagenic effects of cosmetics by Ames assay;

Twelve vegetable extract samples covering four species (pakchoi, celery, spinach and leaf lettuce) cultivated in different industrial pollution areas in Shanghai suburbs were specially prepared to detect their mutagenecity by Ames assay.

Methods:The number of revertant colonies of positive contrast group in the presence of different dose of S9 were compared in Ames assay respectively,and mutant frequency of positive control were compared in chromosome aberration,content of protein was determined by the method of Lowry,and content of P450.

To detect the different mutagenicities,cytotoxicities of Fructus Aristolochiae(FA)and Long-Dan-Xie-Gan-Wan (LDXGW),single and compound prescriptions in Chinese Traditional Medicine(CTM)respectively,via the means of Ames Test and Mouse Lymphoma Assay(MLA).
