Detailed Description:

The study tested - all by skin tests - in the same group of 20 trial subjects, one positive control (histamine solution), one negative control (placebo saline) and five experimental peptides called T1, T2, T3, T4 and T5. Results of the skin prick tests were scored as negative (no reaction) or positive (wheal diameter > 4 mm with erythema)
