          Objective: Electroacupuncture (EA) has been used to treat myalgia, adiposis and gastroenteropathy in Korea. EA as a complementary and alternative medicine has been accepted worldwide mainly for the treatment acute and chronic pain and inflammation. The aim of this study was to investigate the effects of EA on acute pancreatitis induced by cholecystokinin octapeptide (CCK) in rats. Methods: Animals were divided into four groups: (1) a normal group; (2) a CCK-induced acute pancreatitis group; (3) a CCK-induced acute pancreatitis group treated with 100-Hz EA, and (4) a CCK-induced acute pancreatitis group treated with 2-Hz EA. High-frequency (100-Hz) and low-frequency EA (2-Hz) stimulations were applied to an acupoint equivalent to Zusanli (ST36) in rats, followed by 75 µg/kg CCK subcutaneously three times, after 1, 3 and 5 h. The entire procedure was repeated over 5 days. Repeated CCK treatment resulted in typical laboratory and morphological changes in experimentally induced pancreatitis. Results: EA significantly decreased the pancreatic weight/body weight ratio in CCK-induced acute pancreatitis, increased the pancreatic levels of HSP60 and HSP72, and decreased the β-amylase and lipase levels associated with CCK-induced acute pancreatitis. Furthermore, the release of ACTH was increased in the blood serum of the EA-treated group. Conclusion: EA may have protective effects against CCK-induced acute pancreatitis through the release of ACTH.

              Anti-inflammatory actions of acupuncture.

              Acupuncture has a beneficial effect when treating many diseases and painful conditions, and therefore is thought to be useful as a complementary therapy or to replace generally accepted pharmacological intervention. The attributive effect of acupuncture has been investigated in inflammatory diseases, including asthma, rhinitis, inflammatory bowel disease, rheumatoid arthritis, epicondylitis, complex regional pain syndrome type 1 and vasculitis. Large randomised trials demonstrating the immediate and sustained effect of acupuncture are missing. Mechanisms underlying the ascribed immunosuppressive actions of acupuncture are reviewed in this communication. The acupuncture-controlled release of neuropeptides from nerve endings and subsequent vasodilative and anti-inflammatory effects through calcitonine gene-related peptide is hypothesised. The complex interactions with substance P, the analgesic contribution of beta-endorphin and the balance between cell-specific pro-inflammatory and anti-inflammatory cytokines tumour necrosis factor-alpha and interleukin-10 are discussed.
