Protective effect of lactoferrin on caerulein-induced acute pancreatitis in rats.

In rats we studied the effects of lactoferrin on experimental acute pancreatitis caused by a single subcutaneous injection of 100 micrograms/kg body weight of caerulein. Lactoferrin isolated from human milk was given intraperitoneally to rats immediately after the injection of caerulein. The injection of 100 mg/kg body weight of lactoferrin significantly reduced the elevation of the serum amylase level and pancreatic wet weight; histological alterations of the pancreas were markedly suppressed. These results suggested that lactoferrin had a protective effect on the biochemical and histological alterations in this model.
