We find that adding the effect from the one-pion exchange axial charge density and using the same scheme of calculations does not change situation to the value of g_P.8 pages, 1 figure, in Proceedings of the 7th Conference "Mesons and Light Nuclei '98", Prague-Pruhonice, Czech Republic, 31 August - 4 September 1998, eds.
