You need to run the following on that database and post the results here:

DBCC CHECKDB({your database}) WITH all_errormsgs, no_infomsgs;

What you posted before does not show the errors and we need to see all of the errors to determine what needs to be done. I would start by identifying a clean backup and start getting prepared to restore from that backup. In most cases, the easiest and best way to recover from an integrity problem is to restore.
