Formation of slightly soluble complexes between the small aggregates (dimers to tetramers) of bile salts and divalent cations, Cu 2/ , Cd 2/ , and Fe 2/ (Me 2/ ), have been studied using polarography to determine concentration of free aquo ions. Polarography has been proved to be useful for studying

The ability of trout to metabolize aniline in vitro in the presence of some divalent metal ions was investigated in the liver microsomes of rainbow trout, Salmo gairdneri. Trout liver microsomes were highly capable of catalyzing aniline hydroxylation to p-aminophenol with a specific activity of 0.06
## Abstract Changes in the conformation of poly(G), poly(C), poly(U), and poly(I) in the presence of divalent metal ions Mg^2+^, Ca^2+^, Mn^2+^, Co^2+^, Ni^2+^, Cu^2+^, Cd^2+^, and Zn^2+^ have been measured by means of ORD and u.v. spectra. Mg^2+^ and Ca^2+^ ions stabilize helical structures of all
