BACKGROUND: In an attempt to obtain evidence of the beneficial effects of TJ-10, we investigated the gene expression of PAP, an acute phase protein specific for pancreatitis in rat spontaneous chronic pancreatitis.
METHODS: Four-wk-old male WBN/Kob rats were fed with MB-3 pellet diet containing herbal medicine. There were two administration groups for each drug: the prophylactic group administered from 4-12 wk, and the therapeutic group administered from 12-20 wk. Untreated control rats were fed with MB-3 alone. Histopathologic changes and PAP gene expressions were analyzed at 12 and 20 wk.
RESULTS: In the prophylactic group, TJ-10-treated WBN/Kob rats showed no evidence of pancreatitis, and there was the amelioration of pancreatitis in the pancreata of the rats treated with other herbal medicines except TJ-24 at 12 wk. PAP mRNA was not expressed in the TJ-10-treated rats, and PAP gene expression was suppressed in rats treated with other drugs except TJ-107. In the therapeutic group, the amelioration of pancreatitis was seen only in TJ-10-treated rats, but PAP gene expression was significantly suppressed in the rats treated with all herbal medicines tested, compared with that in untreated control rats.
CONCLUSION: An herbal medicine Saiko-keishi-to (TJ-10) delayed the onset of chronic pancreatitis in the WBN/Kob rat, and suppressed the pancreatitis-associated protein (PAP) gene expression more significantly than other herbal medicines.
