| Abstract: | The effect of disodium cromoglycate (DSCG) on antigen-evoked histamine release from IgE-sensitized human skin in vitro has been studied using breast skin from six donors. Concentrations of DSCG ranging from 10–200 μM did not produce any consistent effect on histamine release, the results ranging from moderate inhibition to moderate enhancement. With higher concentrations of DSCG (400–500 μM) enhancement of release occurred in nearly all experiments. Variation of antigen concentration did not modify the response to DSCG. These results do not support the possibility that DSCG may be effective in the treatment of immediate hypersensitivity reactions in human skin. |
