The clinical details and neuropathological findings of a Coloured South African with multiple sclerosis are presented. The interest of this case lies in the fact that this is the first proven case of multiple sclerosis in a Coloured South African.

A two-parametric non-standard (Jordanian) deformation of the Lie algebra gl(2) is constructed, and then, exploited to obtain a new, triangular R-matrix solution of the coloured Yang-Baxter equation. The corresponding coloured quantum group is presented explicitly.
