Abstract
OBJECTIVES Mesenchymal stem cells (MSCs) have shown an obvious protective effect on systemic inflammation. The purpose of this study is to assess the effect and possible mechanism of bone marrow MSCs (bmMSCs) on acute pancreatitis (AP). METHODS BmMSCs of SD rats were isolated and cultured in vitro. L-Arginine-induced acute pancreatitis was used as AP model in vivo. Pancreatic injury was assessed by serum amylase, lipase, cytokines and pancreatic histology. RT-PCR was applied to investigate mRNA expression of pancreas tissue. Western-blot and immunohistochemistry (IHC) were applied to test the role of NF-κB p65 signaling pathway. Tracking and Positioning of CM-Dil labeled bmMSCs in vivo was further studied. RESULTS Treatment with bmMSCs attenuated acute pancreatic injury and AP-associated lung injury obviously, with decreased serum IL-1β, IL-6, TNF-α, down-regulated expressions of IL-1α, IL-6, TNFα in pancreas tissue and reduced nuclear translocation of NF-κB p65 in AP. Localization of bmMSCs in vivo was due to being passively trapped in related organs, but not actively homing to inflammatory sites of pancreas during the early phase of AP. CONCLUSIONS Taken together, the results showed that bmMSCs played a protective role in AP in many aspects, which might protect against experimental pancreatitis partly by regulating release of inflammatory cytokines by an exocrine secretion.

Diosmetin ameliorates the severity of cerulein-induced acute pancreatitis in mice by inhibiting the activation of the nuclear factor-κB. Int J Clin Exp Pathol 2014; 7:2133-2142.

Abstract
Diosmetin (3', 5, 7-trihydroxy-4'-methoxyflavone), the aglycone part of the flavonoid glycosides diosmin occurs naturally in citrus fruit, was considered to exhibit anti-inflammatory and antioxidant properties. Our study aimed to investigate the effect of diosmetin in a murine model of cerulein-induced acute pancreatitis (AP). Experimental AP was induced in mice by seven intraperitoneal injection of cerulein (50 ug/kg) at hourly intervals. Diosmetin (100 mg/kg) or vehicle was pretreated 2 h before the first cerulein injection. After 6 h, 9 h, 12 h of the first cerulein injection, the severity of acute pancreatitis was evaluated biochemically and morphologically. Pretreatment with diosmetin significantly reduced serum levels of amylase and lipase; the histological injury; the secretion of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6; myeloperoxidase (MPO) activity, trypsinogen activation peptide (TAP) level, the expression of inducible nitric oxide synthase (iNOS); and the nuclear factor (NF)-κB activation in cerulein-induced AP. This study showed that administration of diosmetin demonstrated a beneficial effect on the course of cerulein-induced AP in mice. Therefore, diosmetin may become a new therapeutic agent in future clinical trials for treatment of AP.
