We investigate the existence of positive solutions of a Dirich let problem for the system
$$ - \Updelta u = f(v),\,\Updelta v = g(u) $$
in a bounded convex domain Ω of
$$ {\mathbb{R}}^{N} $$
with smooth boundary. In particular
L

a priori bounds are obtained in the same spirit as in De Figueiredo—Lions—Nussbaum [7].
