The mass levels of vector octet (w, p, K*) and pseudoscalar octet (rr, K, rr01 ) are evaluated on the basis of the Fermi-Yang-Sakata model by the N/D method. We assume that x, w, p, rr, etc., are gluons of baryons and antibaryons, and, since they are also bound state of baryons and antibaryons (Regge poles), our theory is divergencefree. We also discuss the possibility that the masses and the coupling constants of bosons should be determined from the unsubtracted dispersion integral of baryon-antibaryon scat tering in a self-consistent way analogously to Chew-Mandelstam-Zachariasen's theory on the p-wave pion-pion resonance, if all bosons are a pure compound state of baryons and anti baryons.
