Protective Effects of Rhubarb in Rats with Acute Pancreatitis and the Role of Its Active Compound Rhein on Mitochondria of Exocrine Cells

Da-Cheng-Qi-Decoction (DCQD) has been used in the treatment of acute pancreatitis (AP) in China for many years. The aim of the current study was to examine the principal ingredient rhubarb of DCQD and its potential link to the pancreatic repair effects in rats with AP. The pancreatitis was induced in SD rats by intraperitoneal injections of cerulein. The results showed that rhubarb significantly increased blood perfusion of pancreatic tissue, reversed mitochondrial damage, and promoted pancreatic acinar and stellate cell proliferation. In addition, the rhein (from rhubarb) had high distribution in pancreas tissue and protected mitochondria in AR42J cells via the activation of PI3K/AKT/mTOR signaling pathway and activity inhibition of AMPK (P
