Figure 3

Lack of effect of storage time upon extent of erythema induced by methylnicotinate. 10 mM aqueous solutions of methylnicotinate prepared from stock solutions which had been stored for various lengths of time at 4°C were applied to the forearm of 8 healthy volunteers and the induced erythema assessed visually at 5, 10 and 15 minutes post-application using a 4-point scale. Values shown are mean erythema; bars indicate the standard deviation.
