Replication errors 8951,8955

Hi,
I made some schema changes to my publication database, and now I get the following errors when I run DBCC CHECKDB:
Server: Msg 8951, Level 16, State 1, Line 1
Table Corrupt: Table 'sysarticles' (ID 16). Missing or invalid key in index 'unc1sysarticles' (ID 2) for the row:
Server: Msg 8955, Level 16, State 1, Line 1
Data row (1:258:0) identified by (RID = (1:258:0) ) has index values (artid = 42 and pubid = 1).

I tried to remove the replication, and reset it, but I cannot do this. The reason I did this was because the error numbers have no recommended course of action in the sql server books online. Any thoughts would really help, or possibly a better place to research errors! Thanks,
Jason
