ABSTRACT
This study was undertaken to investigate the optimal conditions for challenge testing with DNCB in 3 vehicles applied to guinea pigs in standardized amount/ area (pg/cm2) The results are sumrnarized as follows 1) All test reactions were negative when tested in 10 unsensitized animals. 2) There were significant difference in positive rate between 0. 05%, DNCB in alcohol and 0.1% DNCB in alcohol, but there were no significant difference between 0. l%, DNCB in alcohol and 0, 2% DNCB in alcohol. Same results were obtaincd when DNCR was dissolved in acetone. 3) Acetone gives the significantly higher degree of positive reactions, indicating that alcohol may be the safer vehicle in eliciting a response than acetone. 4) With DNCB in olive oil, relatively few animals reacted compared to the results obtained with alcohol and acetone. Furthermore, olive oil is slippery and difficult to utilize when attempting to delineate surface area. 5) With alcohol, we obtained a good correlation between the amount applied and the resulting response, showing that this vehicle might be a superior vehicle in eliciting contact allergy.
