In a weak acid medium, when an isopoly-tungstic acid reacts with berberine to form an ion-association complex, strong resonance Rayleigh scattering (RRS) appears and obvious frequency-doubling scattering (FDS) as well as second-order scattering (SOS) come into being. The scattering peaks

Anionic activation of rod outer segment phosphodiesterase by vanadate, molybdate and tungstate is demonstrated. Comparisons are made to adenylate cyclase, which is known to be activated by vanadate and molybdate but not by tungstate. In view of the differences in
