I have upgraded magento C.E 1.5 to 1.8.1.0 through magento connect after the upgrade, I logged in to the magento admin panel and all the menus are disappeared.
I am unable to track as there is no error but none of the menus are shown.
Please help if anyone have already gone through with the same problem.
Thanks in advance.

Looks like you don't have permissions for your admin user. Try to delete the cookies for that domain to get a new php session.
Or recreate the tables for admin users/roles. Have a clean install of Magento 1.8 and import those clean good tables. Do this on a test/developing server first. And backup the database and code first of all, even if it's a test server.
