Abstract：
:A predictive test using mice for the identification of contact sensitizing chemicals was developed. Contact sensitizing activity is measured as a function of draining lymph node activation following application of test chemical. Experimental conditions for assessment of induced lymph node cell (LNC) responses have been optimized. BALB/c mice were initially treated with intradermal injections of test chemical in Freund's complete adjuvant emulsion. Five days after intradermal injection, mice were exposed topically to chemical in vehicle on the ears daily for 3 consecutive days. Next day following the final exposure, changes in lymph node weight, total cell number in the draining lymph nodes and LNC proliferation for 24 h culture were assessed. The performance of the method was evaluated with ten sensitizing chemicals and a non-sensitizing irritant, sodium lauryl sulfate (SLS). The LNC proliferation induced by combination of intradermal injection and topical application of sensitizing chemicals was more clearly increased than that following only topical application. With the single exception of sulfanilic acid, the method developed was able to detect the sensitizing capacity of chemicals that failed to induce sensitization in the local lymph node assay. Under the conditions used, SLS did not induce measurable lymph node responses. These results suggest that the mouse lymph node assay can provide a sensitive screening test for weak to moderate sensitizers. In addition, the assay offers the advantages of objective and quantitative endpoints, and is suitable for the evaluation of colored or irritant chemicals.
