Short term effect of Salvia miltiorrhiza in treating rat acetic acid chronic gastric ulcer and long term effect in preventing recurrence.
AIM:To study the short-term effect of Danshen (Salvia miltiorrhiza) on acetic acid induced chronic gastric ulcer in rats and its long-term effect in preventing recurrence.METHODS:Rats with acetic acid-induced gastric ulcer were treated with Danshen and cimetidine for 30 days.Traditional gastric mucosal auto-radiography and (3)H-TdR incorporation into gastric mucosa in vitro were employed to study the effects of Danshen in rat acetic acid-induced chronic gastric ulcer, including ulcer index (UI), ulcer inhibitory rate (IR) and label rate (LR).RESULTS:On the day 5, 30 and 126 of ulcer-making, the UI in the Danshen group was obviously lower than that in the cimetidine group and the control group (42.3 ± 3.9, 3.6 ± 1.2, 4.4 ± 2.3; 49.1 ± 3.6, 5.9 ± 1.4, 9.2 ± 1.3; 61.0 ± 3.8, 8.9 ± 2.5, 12.4 ± 2.4, respectively, P < 0.01), the IR (%) in the Danshen group was obviously higher than that in the cimetidine group (31, 59, 64.8; 19, 33, 26, respectively), and the LR in the Danshen group was obviously higher than that in the cimetidine group and the control group (10.0 ± 0.5,16.2 ± 0.8, 15.0 ± 0.6; 9.0 ± 0.5, 13.9 ± 0.6, 10.8 ± 0.7; 6.5 ± 0.7, 10.1 ± 0.5, 8.0 ± 0.7, respectively, P < 0.01). There was no obvious difference in UI in the Danshen group on day 30 as compared with that on day 126.CONCLUSION:Danshen is effective in promoting ulcer healing and preventing recurrence. The mechanism of action is to strengthen the gastric mucosal barrier and to promote the gastric mucosal cell proliferation along the edge of the ulcer.
