title: Comparison of the PCA titer and aerosol microshock time in guinea pigs made sensitive to ragweed.
abstract: Guinea pigs were sensitized either by intranasal dusting with ragweed (RW) pollen or by intranasal instillation of RW extract and subsequently challenged with a RW extract aerosol. It was relatively easy to determine the microshock time for animals which responded between 0 and 10 minutes. Sera from these sensitive guinea pigs were tittered by passive cutaneous anaphylaxis tests. Data from these two assays showed a semilogarithmic relationship with a correlation coefficient of -0.934.
