[wp-hackers] Change Word Throughout Installation in Admin Panel

[mailapera]

Hi,
I installed WP in Spanish and I am trying to change the word that
stands for "article" throughout the admin pages with another word. I
edited the language files searching and replacing all instances of the
translation given for article, but once I reload, clear cache and so
on no change appears.

How can I do this? Am I missing something? Do I need to change some
database entries also? Thanks
