  The self-consistent treatment of real and imaginary renormalizations in the
dynamic spin susceptibility for the frustrated Heisenberg model reproduces for
cuprates at low doping: a spin spectrum, a saddle point for q near (pi/2,pi/2),
nearly constant q-integrated susceptibility for energy less than 150 meV and a
scaling law. Frustration increase (optimally doped case) leads to a stripe
scenario with a saddle point at q near (pi,pi/2) and $\chi_{2D}(\omega)$ peak
near 30meV. The obtained $\chi (\mathbf{q},\omega)$ describes neutron
scattering results and leads to well-known temperature transport anomalies in
doped cuprates.
