2 FIG. 1 Representative histologic findings of mite allergen-induced dermatitis. A, Control. B, Six hours after patch test. Note epidermal spongiotic changes. C, Forty-eight hours. Epidermal vesicle consisting of eosinophils. D, Two hours. Several perivascular small mononuclear cells. Note the presence of eosinophils attached to the vascular endothelium. E, Six hours. Perivascular eosinophil infiltration along with occasional small mononuclear cells. F, Forty-eight hours. Note the prominent eosinophil infiltration.

8 FIG. 2 Detection of cytokine mRNA by RT-PCR. As for IL-4, IL-5, and TNF-α, the products after two cycles of PCR are shown. The band corresponding to IL-4 is visible at 12 and 24 hours after application of mite antigen. Expression of IL-5 and TNF-α is increased during the time course.

9 FIG. 3 Staining patterns with anti-IL-4 antibody. A, Two hours after the patch test. B, Six hours. C, Twenty-four hours. D, Two hours. Positive cell is presumably mast cell. E, Six hours. F, Twenty-four hours. Majority of infiltrating cells remain unstained. Journal of Allergy and Clinical Immunology  , DOI: ( /S (95) ) Copyright © 1995 Mosby, Inc. Terms and Conditions
