Visnagin attenuates acute pancreatitis via Nrf2/NFκB pathway and abrogates associated multiple organ dysfunction.
    Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie, 2019, Volume: 112

    Acute pancreatitis (AP) is an exocrine dysfunction of the pancreas where oxidative stress and inflammatory cytokines play a key role in induction and progression of the disease. Studies have demonstrated that antioxidant phytochemicals have been effective in improving pancreatitis condition, but there are no clinically approved drugs till date. Our study aims to assess the preventive activity of visnagin, a novel phytochemical isolated from Ammi visnaga against cerulein induced AP. Male Swiss albino mice were divided into six groups (n = 6, each group) comprising of normal control, cerulein control, seven day pre-treatment with visnagin at three dose levels; visnagin low dose (10 mg/kg), visnagin mid dose (30 mg/kg), visnagin high dose (60 mg/kg) and visnagin control (60 mg/kg). AP was induced by six injections of cerulein (50 μg/kg, i.p.) on the 7

Early organ-specific mitochondrial dysfunction of jejunum and lung found in rats with experimental acute pancreatitis.
    HPB : the official journal of the International Hepato Pancreato Biliary Association, 2011, Volume: 13, Issue:5

    Multiple organ dysfunction is the main cause of death in severe acute pancreatitis. Primary mitochondrial dysfunction plays a central role in the development and progression of organ failure in critical illness. The present study investigated mitochondrial function in seven tissues during early experimental acute pancreatitis.. Twenty-eight male Wistar rats (463 ± 2 g; mean ± SEM) were studied. Group 1 (n= 8), saline control; Group 2 (n= 6), caerulein-induced mild acute pancreatitis; Group 3 (n= 7) sham surgical controls; and Group 4 (n= 7), taurocholate-induced severe acute pancreatitis. Animals were euthanased at 6 h from the induction of acute pancreatitis and mitochondrial function was assessed in the heart, lung, liver, kidney, pancreas, duodenum and jejunum by mitochondrial respirometry.. Significant early mitochondrial dysfunction was present in the pancreas, lung and jejunum in both models of acute pancreatitis, however, the Heart, liver, kidney and duodenal mitochondria were unaffected.. The present study provides the first description of early organ-selective mitochondrial dysfunction in the lung and jejunum during acute pancreatitis. Research is now needed to identify the underlying pathophysiology behind the organ selective mitochondrial dysfunction, and the potential benefits of early mitochondrial-specific therapies in acute pancreatitis.

    Inflammation, 2004, Volume: 28, Issue:5

    The investigation of the effects of the celecoxib as a cylooxygenase-2 (COX-2) inhibitor on the course of the acute necrotising pancreatitis (ANP) in rats. ANP was induced in 72 rats by standardized intraductal glycodeoxycholic acid infusion and intravenous cerulein infusion. The rats were divided into four groups (six rats in each group): Sham + saline, sham + celecoxib, ANP + saline, ANP + celecoxib. Six hours later after the ANP induction, celecoxib (10 mg/kg) or saline was given i.p. In the 12th hour, routine cardiorespiratuar, renal parameters were monitored to assess the organ function. The serum amylase, alanine amino transferase (ALT), interleukin 6 (IL-6), lactate dehydrogenase (LDH) in bronchoalveolar lavage (BAL) fluid, the serum concentration of the urea, the tissue activity of myeloperoxidase (MPO) and malondialdehyde (MDA) in pancreas and lungs were measured. The pancreas histology was examined. In the second part of the study, 48 rats were studied in four groups similar to the first part. Survival of all the rats after the induction of ANP was observed for 24 h. The induction of the pancreatitis increased the mortality from 0/12, in the sham groups to 4/12 (30%) in the acute pancreatitis with saline group, 5/12 (42%) in the acute pancreatitis with celecoxib group respectively, heart rate, the serum activities of amylase, ALT, the tissue activities of MPO, MDA in the pancreas and lung, and LDH in BAL fluid, the serum concentration of the urea and IL-6, the degree of the pancreatic damage and decreased the blood pressure, the urine production, pO(2) and the serum concentration of calcium. The use of celecoxib did not alter these changes except the serum IL-6 concentration, urine production and MPO, MDA activities in the tissue of the lungs and pancreas. Serum urea concentration and pancreatic damage in ANP + celecoxib group were insignificantly lesser than ANP + saline group. Whereas treatment with celecoxib improves lung and renal functions, the degree of pancreatic damage partially and the serum IL-6 level completely, it does not improve the cardiovascular and liver functions, the mortality rate and the calcium level. Celecoxib may be useful for the support of some organ functions during ANP in rats.

Hepatocyte growth factor increases in injured organs and functions as an organotrophic factor in rats with experimental acute pancreatitis.
    Pancreas, 2000, Volume: 20, Issue:1

    We previously reported that serum hepatocyte growth factor (HGF) levels are elevated in patients with acute pancreatitis and that pancreatitis-associated ascitic fluid (PAAF) contains cytotoxic factor(s) inducing apoptosis on Madin-Darby canine kidney (MDCK) cells. In this study, plasma HGF levels and HGF tissue distribution were investigated in rats with experimental acute pancreatitis, and the effects of HGF on the cytotoxic activity and apoptosis-inducing activity of PAAF also were examined. Plasma HGF levels were elevated in rats with two experimental pancreatitis models of different grades of severity. The degree of its elevation was correlated with the severity and the organ dysfunctions. In rats with severe pancreatitis, HGF protein and messenger RNA (mRNA) levels significantly increased in liver, kidney, and lung, which were injured organs. When anti-HGF neutralizing antibody was administered in severe pancreatitis, liver dysfunction worsened, and apoptotic cells increased in kidney. Recombinant HGF inhibited the cytocidal activity of PAAF on MDCK cells in a dose-dependent manner. Moreover, recombinant HGF prevented the apoptotic cell death (DNA fragmentation, nuclear fragmentation, and caspase-3 activation) induced by PAAF. These results suggest that HGF is produced in injured organs and may function as an organotrophic and antiapoptotic factor against the organ injuries in acute pancreatitis.

Extrapancreatic organ impairment in caerulein induced pancreatitis.
    Annales chirurgiae et gynaecologiae, 1999, Volume: 88, Issue:2

    Multiorgan function failures are the major fatal complications in acute pancreatitis. In this experiment, we studied 1) the manifestation and time course of extrapancreatic organ damage in an acute pancreatitis model and 2) whether the obstructive liver damage in this model is caused by the obstruction of common biliopancreatic duct compressed by oedematous pancreas.. 80 male Wistar rats were divided into two groups: control and caerulein groups (five subgroups in each group). In the caerulein group, the acute pancreatitis was induced by caerulein intraperitoneal injections. In the controls equal volume of saline was injected. Two subgroups, one in caerulein and one in control groups, had an intrapancreatic bile duct stent inserted transduodenally before the injections. The pancreas, liver, lung and kidney tissues and blood samples were obtained for the measurement or analysis of interstitial oedema, plasma amylase, alanine aminotransferase, bilirubin, urea, creatinine, alkaline phosphatase, lactate dehydrogenase, blood gas and electron microscopy at 1, 6, 12 and 24 hours after the last injection in unstented animals, and at 6 hours in stented animals.. Lungs and kidney remained unchanged. Liver damage was found during the first 6-12 hours, manifest as increased plasma alanine aminotransferase and bilirubin and dilatation of bile canaliculi and hepatocyte damage in electron microscopy. The intrapancreatic bile duct stent did not resolve these changes.. The liver may be the first evolved extrapancreatic organ in the early stage in this mild oedematous pancreatitis model and the hepatocyte damage is not caused by the obstruction of common biliopancreatic duct compressed by the oedematous pancreas.

Protective effects of a PAF receptor antagonist and a neutrophil elastase inhibitor on multiple organ failure induced by cerulein plus lipopolysaccharide in rats.
    Naunyn-Schmiedeberg's archives of pharmacology, 1998, Volume: 358, Issue:2

    The inhibitory effects of YM264, a selective platelet activating factor (PAF) receptor antagonist, and 2-(3-methylsulfonylamino-2-oxo-6-phenyl-1,2-dihydro-1-pyridyl)-N-( 3,3,3-trifluoro-1-isopropyl-2-oxopropyl)acetamide (compound 1), a neutrophil elastase inhibitor, on mortality, and pancreatic, hepatic, renal and pulmonary dysfunction were evaluated in a rat model of multiple organ failure (MOF) accompanying acute pancreatitis. MOF was produced by intraperitoneal injection of lipopolysaccharide (LPS, 30 mg/kg) in rats with cerulein-induced pancreatitis. LPS dose-dependently increased the mortality in rats with or without pancreatitis. The threshold dose which produced death in rats without pancreatitis was 30 mg/kg. This same dose evoked death in more than 40% of rats with pancreatitis. Time-course changes in serum enzyme and organ myeloperoxidase (MPO) levels were first examined in rats with induced MOF, and the results were compared with those in rats treated with only LPS or cerulein. Pancreatic weight, and serum amylase and lipase levels significantly increased in rats with cerulein-induced pancreatitis despite the presence or absence of LPS, but recovery of these pancreatic dysfunctions was slower in the group given LPS. However, serum GOT, GPT, BUN and creatinine levels were significantly elevated only in MOF rats. In the MOF rats, the MPO level in the lung was significantly elevated and arterial oxygen pressure was decreased, indicating that infiltration of neutrophils into the lung might be involved in pulmonary dysfunction. However, the MPO levels in the pancreas and kidney in the MOF rats were not remarkably different from those in normal rats. The inhibitory effects of YM264 and compound 1 on mortality and organ dysfunction were examined in this MOF model. The 24-h survival rate for rats prophylactically and therapeutically treated with an intravenous infusion of YM264 at 0.1 mg/kg h was significantly higher than that of controls. The 24-h survival rate for rats treated prophylactically by intravenous infusion of 2 mg/kg h of compound 1 was significantly higher than that of control, whereas a beneficial dose of compound 1 was 5 mg/kg h in therapeutically treated rats. Prophylactic treatment with YM264 (0.1 mg/kg h) and compound 1 (2 mg/kg h) ameliorated organ dysfunction in rats with MOF. In conclusion, pancreatic, hepatic, renal and pulmonary dysfunctions are observed in this rat MOF model. The PAF receptor antagonist and neutrophil elastase

The role of tumor necrosis factor-alpha in the aggravation of cerulein-induced pancreatitis in rats.
    International journal of pancreatology : official journal of the International Association of Pancreatology, 1993, Volume: 14, Issue:2

    Severe acute pancreatitis is often complicated by intraperitoneal infection, resulting in multiple organ failure (MOF). It is known to elevate serum tumor necrosis factor (TNF-alpha) in patients with sepsis and/or MOF. In order to study the role of TNF-alpha in the aggravation of acute pancreatitis, we investigated TNF-alpha production by peritoneal macrophages in acute pancreatitis rat using the cerulein-induced pancreatitis model. TNF-alpha production by isolated peritoneal macrophages following lipopolysaccharide (LPS) stimulation was significantly increased in pancreatitis rats as compared with nonpancreatitis control rats (p < 0.001). Serum TNF-alpha activity was elevated following intraperitoneal administration of LPS as the septic challenge both in pancreatitis rats and in control rats, being significantly higher in the former (p < 0.05). Histological findings and liver function tests revealed that LPS induced more severe liver damage in pancreatitis rats than in control rats within 24 h after LPS administration. These results indicate that increased TNF-alpha production by peritoneal macrophages in acute pancreatitis augmented LPS-induced liver injury and suggest the possibility that TNF-alpha may play a role in the development of MOF during acute pancreatitis complicated by intraabdominal sepsis.
