Nypa fruticans Wurmb. (NF) has been used as a folk remedy to treat inflammatory diseases in Asia. In this study, we aimed to investigate the protective effect of NF water extract on cerulein-induced acute pancreatitis (AP). To measure the protective effects of NF on AP, AP was induced via intraperitoneal injection of cerulein (50 ㎍/kg) hourly for 6 h in mice. NF water extract (100, 250, or 500 mg/kg) or saline was administrated to intraperitoneal injection 1 h before the first injection of cerulein. The mice were sacrificed at 6 h after the final injection of the cerulein. Pancreas, and blood sample were taken for further analysis. Administration of NF water extract inhibited the pancreatic injury, the elevation of pancreatic weight/ body weight ratio, and the elevation of serum digestive enzymes such as amylase and lipase during cerulein-induced AP in mice. Also, pancreas MPO activity, which represents neutrophil infiltration, was inhibited by administration of NF water extract. Taken together, administration of NF water extract reduces the severity of cerulein-induced AP, which suggests a clinical basis that NF could be a potential agent to prevent AP.

Objectives: Terminalia chebula Retzins (TC) has been used as a traditional remedy to treat gastrointestinal infectious and inflammatory diseases. However, the protective effect of TC on acute pancreatitis (AP) has not been studied. In this study, we tried to investigate the protective effect of TC water extract on cerulein-induced AP. Methods: To measure the protective effect of TC on AP, mice were injected with cerulein (50 ㎍/kg) hourly for 6 times. TC water extract (200 or 400 mg/kg) or saline was administered orally 1 h before the first injection of cerulein. The mice were sacrificed at 6 h after the last injection of cerulein. Pancreas tissues were taken for further analysis. Results: The administration of TC water extract showed an inhibitory effect on the increase of pancreas weight/body weight ratio and mitigated pancreatic damage in mice. Also, mRNA level of pro-inflammatory cytokines was inhibited by administration of TC water extract. Conclusion: Taken together, we found that administration of TC water extract ameliorates the severity of cerulein-induced AP, which suggests the potential to be an effective treatment on AP.

An English bulldog, three years old, hospitalzed as vomitting, severe abdominal pain and intermittent body tremor. In blood examination, WBC, amylase, alkaline phosphatase value showed higher than normal value, so we diagnosed as acute pancreatitis. The bulldog was treated with fluid therapy as Ringer's solution, saline and 5% dextrose, and antibiotics as mixed penicillin with streptomycin, and cephazolin. To prevent shock, dexamethasone was medicated in early time. Also the bulldog was medicated as banamine, vitamine K, atropine and cimetidine. When the English bulldog showed improvement we gave him hill's i/d continuously. Through these procedure, the English bulldog recovered completely.

In this study, we aimed to investigate the effect of GamiChungYi-tang(GCY-t) on caerulein-induced acute pancreatitis (AP). It is performed by detecting oxidative stress markers and observing histopathological examination. Thirty adult male rats(Sprague-Dawley) were divided into six groups as follows: normal (NOR,n=5), caerulein-induced (CON,n=5), caerulein+Cefotaxime Sodium(CT,n=5), caerulein+GCY-t (130 mg/kg, CHA,n=5), caerulein+GCY-t (260 mg/kg, CHB,n=5) and caerulein+GCY-t (520 mg/kg, CHC,n=5) groups. Pancreatic tissues of rats from all groups were removed for apoptosis and light, and electron microscopic examination. Blood of rats from all groups were collected for oxidative stress markers inspection and pathological examination. Pancreatic oxidative stress markers were evaluated by the measurements of leukocyte, serum amylase and platelet activating factor (PAF), Interleukin-6 (IL-6) levels were determined spectrophotometrically. CON group has a significant increase (p<0.05) in amylase compared with NOR, but CT and CHA, CHB, CHC groups reduced the levels of these enzyme. The levels of Platelet activating factor (PAF) were increased in CON compared with NOR, but decreased in CT and CHA, CHB, CHC groups compared with CON. Interleukin-6 (IL-6) levels were increased significantly in CON compared with NOR, but reduced in CT and CHA, CHB, CHC groups. In the observations of Optical microscopy and electron microscopy, The experimental groups showed the significant decreases in pancreatic tissue inflammation, edema, vacuolization, necrosis compared to the control group. After all, GCY-t is potentially capable of limiting pancreatic damage produced during AP by restoring the fine structure of acinar cells and tissue.

Objectives : This study was designed to investigate the effects of SuJeom-san(SJS) extract in rats with caerulein-induced acute pancreatitis (AP). Methods : We examined changes of pancreatic weight, histological, immunohistochemical and gene expression of cyclooxygenase (COX-2). Thirty-six adult male Sprague-Dawley rats were divided into six groups as follow: normal(Nor), caerulein-induced (Con), caerulein + cefotaxime sodium(CT), caerulein + SJS 3 mg/kg(SJSA), caerulein + SJS 6 mg/kg(SJSB) and caerulein + SJS 12 mg/kg(SJSC) groups. Pancreatic tissues of rats from all groups were removed for histological observation and light, and electron microscopic examination. Platelet activating factor(PAF) and Interleukin-6(IL-6) levels were determined spectrophotometrically. Results : The ratio of pancreas/body weight was significantly(p<0.05) increased in the Con compared with Nor, but significantly(p<0.05) decreased in SJSA, SJSB, SJSC and CT groups compared with Con. Caerulein administration significantly increased(p<0.05) the levels of amylase, but SJSA, SJSB, SJSC and CT significantly(p<0.05) reduced the levels of these enzymes. The levels of platelet activating factor(PAF) increased in Con compared with Nor, but decreased in SJSA, SJSB, SJSC and CT groups compared with Con. Interleukin-6(IL-6) levels increased significantly in all groups compared to Nor at 6 hrs, but significantly(p<0.05) reduced in SJSA, SJSB, SJSC and CT groups compared with Con at 24 hrs. The levels of tumor necrosis factor(TNF)-${\alpha}$ levels increased in all groups compared to Nor at 6 hrs, but significantly(p<0.05) reduced in SJSA, SJSB, SJSC and CT groups compared with Con at 24 hrs. The COX-2 positive materials were observed in the pancreas of the Con, but these positive materials were decreased in the SJS extract treatment group. Conclusion : SJS is potentially capable of limiting pancreatic damage during AP by restoring the fine structure of acinar cells and tissue; therefore, we conclude that SJS may have beneficial effects in the treatment of caerulein-induced AP.

We performed this study to evaluate the potential clinical marker of urinary trypsinogen-2 together with amylase, lipase and urinary amylase creatinine clearance ratio (ACCR) for the diagnosis of acute pancreatitis in dogs. In the experiment on daily changing patterns of amylase, lipase and ACCR measurements in experimentally induced pancreatitis dogs, compared to values measured in pre-induction state, significant difference was seen in amylase until 5th day of induction, and for lipase significant difference was found during the 7th day of observation period (p < 0.05). No significant difference was found in ACCR for the study period (p > 0.05). On SDS-PAGE analysis of urine from experimentally induced pancreatitis dog, The 26kd band was markedly increased compared with that of normal state and that band was confirmed trypsinogen-2 using substrate interaction and isoelectric focusing assay after being eluted. When assessing the appearance of 26kd band on urine SDS-PAGE 87.1% (range: 50~100%) of experimentally induced pancreatitis dogs showed positive results, whereas no corresponding band was seen in dog without pancreatic disorders. With this result, determination of urinary trypsinogen-2 assay was found to have a high diagnostic value with a 70% of sensitivity and 100% of specificity as a routine test for pancreatitis, although the detection of trypsinogen-2 in urine can be varied on the progression stage of pancreatitis at the initial visit to animal clinic. We therefore suggest that the promising results in this study be used for the development of dipstick test for detecting acute pancreatitis in the future research.

Objectives : In this study, we investigated the effects of Daehwangmokdanpitang-gagambang(DMG) on treatment for cholecystokinin-octapeptide(CCK)-induced acute pancreatitis(AP) in rats. Methods : Male Wistar rats weighing 200 to 250 g were divided into three groups. The first was normal untreated group, the second was in treatment with DMG group; DMG was administered orally, followed by 75 ${\mu}g/kg$ CCK subcutaneously three times, after 1, 3 and 5 h. This whole procedure was repeated for 5 days. The third was in treatment with saline group, the protocol was the same as in treatment group with DMG. We determined the pancreatic weight/body weight ratio, the levels of pancreatic HSP60, HSP72, ERK, p38 MAPK and the secretion of pro-inflammatory cytokines. Repeated CCK treatment resulted in the typical laboratory and morphological changes of experimentally induced pancreatitis. Results : DMG was significantly decreased the pancreatic weight/body weight ratio in CCKinduced AP and DMG increased HSP60 and HSP72 compared with CCK-induced AP. DMG suppressed ERK and p38 MAPK activation. Additionally, the secretion of $IL-1{\beta}$ and $TNF-{\alpha}$ and the levels of amylase and lipase were lower than that saline. Conclusions : DMG has an effect to treatment for CCK-induced AP.

Objectives : In this study, we aimed to investigate the effect of Eunhoebanchong-san (EBS) on caerulein-induced acute pancreatitis (AP) by detecting oxidative stress markers and performing histopathological examination. Methods : Thirty adult male Sprague-Dawley rats were divided into five groups as follows: normal (NOR), caerulein-induced (CON), caerulein+EBS (130 mg/kg, EA), caerulein+EBS (260 mg/kg, EB) and caerulein+EBS (520 mg/kg, EC) groups. Pancreatic tissues of rats from all groups were removed for apoptosis, and light, and electron microscopic examination. Blood of rats from all groups was obtained for oxidative stress markers and pathological examination. Pancreatic oxidative stress markers were evaluated by the measurements of serum amylase, and interleukin-6 (IL-6) levels were determined spectrophotometrically. Results : The ratio of pancreas/body weight increased significantly in the CON compared with the NOR, but decreased significantly in the EA, the EB, the EC groups compared with the CON. Caerulein administration resulted in a significant increase in amylase, but EBS reduced the levels of these enzymes. Interleukin-6 (IL-6) levels increased significantly in CON compared with NOR, but reduced in EA, EB, and EC group at 24 hrs. In the observations of optical microscopy and electron microscopy, the experimental groups showed significant decreases in pancreatic tissue inflammation, edema, vacuolization, necrosis compared to the control group. Altogether, this indicates EBS is potentially capable of limiting pancreatic damage produced during AP by restoring the fine structure of acinar cells and tissue. Conclusions : We concluded that EBS may have beneficial effects in the treatment of caerulein-induced AP.
