AIM: To investigate the effect of Gardenia jasminoides (G3) on cerulein-induced acute pancreatitis (AP) in mice. METHODS: C57BL/6 mice weighing 18-20 g were divided into three groups. (1) Normal saline-treated group, (2) treatment with GJ at a dose of 0.1 g/kg, (3) treatment with GJ at a dose of 1 g/kg. GJ was administered orally (η = 6 per group) for 1 wk. Three hours later, the mice were given an intraperitoneal injection of cerulein (50 ug/kg), a stable cholecystokinin (CCK) analogue, every hour for a total of 6h as described previously. The mice were sacrificed at 6 h after completion of cerulein injections. Blood samples were obtained to determine serum amylase, lipase and cytokine levels. The pancreas was rapidly removed for morphologic examination and scoring. A portion of pancreas was stored at -70℃ and prepared for the measurement of tissue myeloperoxidase (MPO) activity, an indicator of neutrophil sequestration, and for reverse-transcriptase PCR (RT-PCR) and real-time PCR measurements. RESULTS: Treatment with GJ decreased significantly.
