T-cell function in atopic dermatitis. Controlled examination of concanavalin A dose-response relations in cultured...

The Concanavalin A (Con A) stimulation response of peripheral lymphocytes in vitro was found to be decreased statistically significant (alpha = 0.005) in patients with light atopic dermatitis, Strictly matched pairs were examined. Using ten graded concentrations of Con A, dose-response relations of the pairs were demonstrated, differences were more evident at lower suboptimal concentrations. Background DNA-synthesis of the patients was elevated.
