Resumen Antecedentes: El ácido ursólico se encuentra en numerosas plantas y se ha informado que tiene efectos antiproteasas, antioxidantes, antiinflamatorios, antimicrobianos, nefroprotectores, hepatoprotectores y cardioprotectores. Objetivo: Este estudio tuvo como objetivo investigar los efectos del ácido ursólico en la pancreatitis aguda inducida por ceruleína. Material y métodos: Treinta y dos ratas albinas Wistar fueron asignadas aleatoriamente a cuatro grupos iguales: grupo simulado, grupo de pancreatitis aguda, grupo de tratamiento y grupo de ácido ursólico. Resultados: Los niveles de amilasa sérica en los grupos de pancreatitis aguda y de tratamiento fueron significativamente más altos que en los otros grupos (p < 0.05). Además, los niveles séricos de IL-1β, IL-6 y TNF-α fueron significativamente más altos en el grupo de pancreatitis aguda en comparación con el grupo de tratamiento. Aunque la actividad oxidante total del tejido pancreático en ambos grupos fue similar, la capacidad antioxidante total del tejido pancreático en el grupo de tratamiento fue significativamente mayor. Conclusión: Se observó que el ácido ursólico reduce el daño al páncreas y órganos remotos en la pancreatitis aguda, al igual que el estrés oxidativo.

Abstract Background: Ursolic acid (UA) is found in many plants, and has been reported to have anti-protease, antioxidant, anti-inflammatory, antimicrobial, nephroprotective, hepatoprotective, and cardioprotective effects. Objective: The purpose of this study was to investigate the effects of ursolic acid in cerulein-induced acute pancreatitis (AP). Materials and methods: Thirty-two Wistar albino rats were randomly assigned to 4 equal groups: Sham, acute pancreatitis, treatment, and ursolic acid group. Results: Serum amylase levels in the AP and treatment groups were significantly higher than in the others (p < 0.05). In addition, serum IL-1β, IL-6, and TNF-α levels were significantly higher in the AP group in comparison with the treatment group. Although pancreatic tissue total oxidant activity in the AP and treatment groups was similar, pancreatic tissue total antioxidant capacity was significantly higher in the treatment group than in the AP group. Conclusions: Damage to the pancreas and remote organs in AP was observed to be reduced by UA. In addition, oxidative stress was observed to be decreased by the effect of UA.

ABSTRACT PURPOSE: To investigate the therapeutic effects of ellagic acid on L-arginin ınduced acute pancreatitis in rats. METHODS: Thirty-two were split into four groups. Group 1 (control) rats were performed only laparotomy, no drugs were administered. Group 2 (control+EA) rats were administered 85mg/kg EA orally. Rats were sacrificed by cardiac puncture 24 hours after the administration. Group3 (AP) 24 hours after intraperitoneal L-arginine administration, rats were sacrificed by cardiac puncture. Group 4 (EA)-(AP): 85mg/kg EA was administered orally after the L-arginine administration. 24 hours later, rats were sacrificed by cardiac puncture. Serum TNF-α, IL-1β, IL-6, total oxidative status (TOS), total antioxidant capacity (TAC), amylase levels were determined in all groups. RESULTS: Group 3 (AP) rats showed significantly raised TOS level as compared to Group1 (control) rats (p<0.001). Following the EA therapy, a decrease in TOS was observed in Group 4 (AP+EA). TAC levels were significantly raised in the Group 4 (AP+EA) compared to the Group 3 (AP) (p=0.003). Group 3 (AP) showed significantly increased TNF-α, IL-1β and IL-6 serum levels as compared to Group 4 (AP+EA). Histopathological changes were supported our result. CONCLUSION: The healing effects of ellagic acid on inflammatory and oxidative stress were confirmed by histopathological and biochemical evaluations of the pancreatic tissue.
