Our previous observation revealed that bovine colostral Lf is transported into the systemic circulation and cerebrospinal fluid from gut-lumen through receptor-mediated transcytosis in calves. Diarrhea caused by Escherichia coli is one of the important causes of infant morbidity and mortality in developing countries. We investigated the effects of bovine lactoferrin (BLf) on lipopolysaccharide (LPS)-induced diarrheogenic activity, gastrointestinal transit (GIT), and intestinal fluid content in mice. LPS accumulated abundant fluid in the small intestine in a dose-dependent manner, induced diarrhea, but decreased the GIT. Pretreatment with BLf significantly attenuated the effects of LPS on the diarrheogenic activity and intestinal content, but reversed the GIT when compared with NG-nitro-L-arginine-methyl ester (L-NAME, a non-selective NOS inhibitor) or indomethacin (an inhibitor of prostaglandin synthesis). Both plasma NO and PGE2 in enterocytes were found to increase in LPS-treated mice and were reversed by BLf. These findings demonstrate that the action of BLf against LPS was specific and it exerts antidiarrheal activity through modulating the cyclooxygenase [NO and PGE2] pathway in the gut. ------>tmu_sno=None ------>sno=3686 ------>authors2=None ------>authors3=None ------>authors4=None ------>authors5=None ------>authors6=None ------>authors6_c=None ------>authors=Tsai S-Y., Liu H.-J., Yang C-P., Tseng C-C., and Tsai LH. ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=None ------>publish_area=None ------>updateTitle=Bovine lactoferrin protects lipopolysaccharide-induced diarrhea modulating nitric oxide and prostaglandin E2 in mice. ------>language=2 ------>check_flag= ------>submit_date= ------>country=None ------>no= ------>patent_SDate=None ------>update_bywho= ------>publish_year=1999 ------>submit_flag= ------>publish_month=None |
