The calculations lead to the determination of the anomalous dimension of these currents. I also discuss problems with different $γ_5$-schemes and their solution by the finite renormalization procedure.9 pages, 2 figures, talk given at the Triangle Graduate School in Particle Physics, Prague, Czech Republic, September 2--10, 1996High Energy Physics - Phenomenologytext
