OXO (10 μM) stimulated ACh release in human NB-, OAB-, and DFMO + MGBG-treated NB and DFMO + MGBG-treated OAB BUC, ACh release from OAB BUC was significantly increased at hour 6 during the OXO stimulation compared with NB BUC, while the release was significantly decreased in DFMO + MGBG-treated NB and DFMO + MGBG-treated OAB BUC. ++P < 0.05 vs. NB, *P < 0.05, **P < 0.01 vs. OAB, #P < 0.05 vs. NB, cells were from 3 OAB and 3 NB subjects.
