The halide complex salts of platinum, chloroplatinites and chloroplatinates, are highly reactive with proteins, with particular affinity for sulphydryl bonds. They can also be histamine liberators (Parrot et al. 1967,1969). These salts thus represent a polar example of a chemical molecule with most of the features which complicate study as allergens. Many of the problems have been resolved and the findings will be given in extenso . Examples of the relevant platinum salts (molecular weight 444 daltons) are ammonium hexachloroplatinate (NH4)2 [Pt Cl ] and te-trachloroplatinate (NH4)2 [PtCm.
