YY/T 0870 reference to OECD test method basic principle, and in accordance with medical Characteristics of equipment/material test methods were appropriate modifications, provides detailed test procedure can be used as GB/T 16886.3 of the left Biography supplement standard toxicity test method. Under YY/T reference in this section OECDNo.471 0870 (1997) method, with or without metabolic activation system, the observation by doctors Sudden treatment equipment/materials induce histidine auxotrophic strains of Salmonella typhimurium (his-) and tryptophan auxotrophic E. coli strain Change in order to assess its potential mutagenicity. Point mutation is the cause of many human genetic diseases. There is positive evidence that points somatic gene oncogenes and tumor suppressor Mutations in human and experimental animal tumor formation. Many test strain due to the many feature, such as a DNA sequence, locus fine reply Increased cell permeability to large molecules, deletions or DNA repair DNA repair system to improve the process of mismatches, etc., and make their projections Become more sensitive detection. Wherein the bacterial reverse mutation test have a quick, inexpensive and relatively easy to operate advantages, etc., can be used to detect DNA base pair substitutions, additions or deletions, providing useful information for genetic mutations induced by toxic substances. Medical Devices genetic toxicity tests Part 1. bacterial reverse mutation assay1 ScopeYY/T 0870 provisions of this part of the Medical Devices/Materials bacterial reverse mutation assay methods. This section is recommended plate incorporation method. NOTE.
