3 Terms and Definitions

GB/T 27830-2011 define the following terms and definitions apply to the text element. 3.1 Cell activity celviability Index measuring overall cell population viability [e.g. mitochondrial dehydrogenase reducing activity tetrazolium dye (3- (4,5-dimethyl-thiazol-2) - 2,5-diphenyl tetrazolium bromide, MTT) (CASN o.298-93-1) capacity], depending on the endpoint measured and the indicators used in the design Program, and with the total number of cells and/or the number of active cells. [GB/T 27830-2011, Definition 2.2] 3.2 The median effective time medianeffectivetime; ET50 Given concentration, resulting in decreased cell viability by 50% the time required. 3.3 IC50 halfmaximalinhibitoryconcentration; IC50 Under certain exposure time, the concentration of cells resulting in reduced activity by 50%. 3.4 Skin irritation skinirritation 4h after contact with the test substance, causing irreversible damage skin. Skin irritation is a local non-immunogenic reaction, stimulated After a short time it will happen. The main features are reversible, including inflammation and irritation associated with the inflammation process of clinical symptoms (red Plaques, edema, itching and pain). 3.5 Optical density opticaldensity; OD The ratio of the intensity of incident light and the transmitted light intensity of the common logarithm. It represents the optical density of the absorption of the test substance. A specific wavelength, with One kind is the concentration of the test object and the energy is absorbed into the quantitative relationship.
