Design outcomes

Primary

MeasureTime frame
Main Objective: In-vivo determination of the biological activity of pollen extracts of Artemisa vulgaris, Platanus acerifoia and Dermatophagoides farinae.;Secondary Objective: In-vivo determination of the biological activity of pollen extracts of Artemisa vulgaris, Platanus acerifoia and Dermatophagoides farinae.;Primary end point(s): Planimetry: The size of the wheal was calculated by planimetry in Bial SA Pharmaceutical Industry and measured in units of mm2. The test is considered positive if the wheal diameter is 3mm, if the diameter is <3 mm the test is considered negative.;Timepoint(s) of evaluation of this end point: 15 minutes after prick test

Secondary
