Abstract
A relativistic formula is derived for the self-energy of $\ensuremath{\rho}$ meson in nuclear matter from a baryonic loop graph containing nucleon and $\ensuremath{\Delta}(1232)$. After identifying the Lindhard function, we find another term in it that contributes appreciably to the real part of the self-energy. We also note small errors that may appear in the numerical calculation owing to the use of incorrect $\ensuremath{\Delta}$ coupling with other fields and presence of quadratic distribution functions in the self-energy formula.
