The homogeneous and isotropic cosmological models in Brans-Dicke theory have been discussed. Besides the cosmological term L(x ) to the Brans-Dicke Lagrangian using Robertson-Walker line element and energy tensor of a perfect fluid were also examined for the mass expansion of the universe. After correcting an error in their work, we also tried to extend our results by calculating cosmological term using Berman and Som [1] solution and showed the results obtained from the application of theory also satisfy uniform cosmological model.
