Llna Ec3 Classification Essay

Recently, an alternative approach for evaluating LLNA dose response data has been proposed which uses non-linear regression analysis of the data. When assigning allergenic potency categories to chemicals with the ECETOC classification scheme it is important to remember that the EC3 cut-off values were derived empirically and that EC3 values themselves, while proven to be robust measures of.

The basic principle underlying the Local Lymph Node Assay (LLNA) in mouse is that sensitizers induce a primary proliferation of lymphocytes in the auricular lymph nodes draining the site of chemical application. This proliferation is proportional to the dose applied and provides a measurement of sensitisation. The method described is based on the use of radioactive labelling to measure cell.

Among the animal tests, the Local Lymph Node Assay (LLNA) is generally used as the gold standard against which the performance of alternative methods is compared (e.g. Piroird et al., 2015, Urbisch et al., 2015). The LLNA provides quantitative information on sensitisation potency expressed as an EC3 value (i.e. the concentration of test chemical required to induce a 3-fold increase in lymph.

The local lymph node assay is deficient in detecting sensitisation by low grade to moderate contact sensitisers, some metals, and organometal compounds. The LLNA was less sensitive compared to the GPMT with types of agents as metals, benzocaine, 4-chloroaniline, neomycin sulfate, streptomycin sulfate, and sulfanilic acid. All were positive in the GPMT. The peer review panel was concerned that.

First, when using the local lymph node assay (LLNA), consider whether an exposure concentration (EC3 value) lower than 100% can be defined and used as a threshold criterion for classification and.

These concentrations were then assessed in terms of how they directly compared to the LLNA EC3 value as well as how they matched the range of the EC3 value (under 1%, 1-10% and over 10%). Finally, clear quantitative relationships between the EC values at 1 mg and the EC3 values were observed using various statistical regression models. These results indicate that results obtained using the.
