The thermodynamic quantities in some excited nuclei are investigated by using extrapolating the experimental level densities. The latest updated nuclear level density (NLD) data below the neutron binding energy $B_n$ is combined with the back-shifted Fermi-gas (BSFG) model for the energy region above $B_n$. The results obtained indicate that the heat capacities of even nuclei show a more pronounced S-shape than those in odd isotopes. The present work also suggests that the energy-dependent level density parameter in the BSFG formula should be used to obtain the best fit to the NLD data in the whole data range.
