Abstract
We have shown that:
- Regional lymphadenectomy in guinea pigs markedly reduces the frequency of sensitization to contact allergens.
- Periumbilical application of allergen regularly results in lower frequencies of contact sensitization than similar exposures on the arm.
- Multiple simultaneous application of allergen to one extremity gives a greater frequency of contact sensitization than an equal number of exposures scattered over three extremities.
- Repeated application of allergen to one extremity produces a greater frequency of contact sensitization than the same number of exposures each on a different limb or body area.
- These findings verify the work of Frey and Wenk and support the idea that the regional lymph nodes play a crucial role in contact sensitization, especially to weak allergens. This concept can be used to advantage in planning predictive patch tests for industrial and cosmetic sensitizers.
