Hell, a sharepoint DB...
Because of the way sharepoint stores the structure of the site in the tables, repairing a sharepoint DB with repair_allow_data_loss can result in an unusable site.
You did take a backup before starting to repair?
I'd honestly suggest restore that pre-repair backup, see if sharepoint will load and then export any and all libraries from sharepoint that will export and then recreate the site.
