  Fluctuations on de Sitter solution of Einstein-Cartan field equations are
obtained in terms of the matter density primordial density fluctuations and
spin-torsion density and matter density fluctuations obtained from COBE data.
Einstein-de Sitter solution is shown to be unstable even in the absence of
torsion.The spin-torsion density fluctuation is simply computed from the
Einstein-Cartan equations and from COBE data.
