The behavior of η and η' in hot strange quark matter in weak equilibrium with temperature, is investigated within the SU(3) Nambu-Jona-Lasinio [NJL] model. Possible manifestations of restoration of symmetries, by temperature or density, in the behavior of η and η' are discussed. The role played by the combined effect of temperature and density in the nature of the phase transition and meson behavior is also analyzed.
