In the expected chirally symmetric phase effective electromagnetic anomalous couplings for e.g. $πσ\to γγ, ~ γ\to πππσ, $ etc., are derived by applying functional methods.6 pages, LaTeX, Talk at the workshop on QCD: Confinement, Collisions, and Chaos, AUP Paris 1996High Energy Physics - Phenomenologytext
