Pre-Clinical Evolutionary Study of Alpha-Pinene in L-Arginine Induced Acute Pancreatitis in Rat
نویسنده
چکیده
Objective: Screening of alpha-pinene on L-arginine induced acute pancreatitis model. Material and Methods: In this model the acute pancreatitis was determined at 24h by determination of pancreatic wet weight/body weight ratio, nitrate/nitrite levels, lipid peroxidation (thiobarbituric acid reactive substances (TBARS)], proinflammatory cytokines [tumor necrosis factor (TNF)-α, C-reactive proteins (CRP) and interleukin (IL)], pancreatic myeloperoxidase (MPO) activity and serum levels of amylase and lipase. Results: Administration of L-arginine had induced pancreatitis and this was characterized by pulmonary complication including altered pancreatic wet weight/body weight ratio, nitrate/nitrite levels, proinflammatory cytokines, TBARS, MPO and serum levels of amylase and lipase. Treatment with alpha-pinene (100 and 200mg/kg) dose significantly attenuated the L-arginine-induced pancreatitis and related complication. Conclusion: The histological findings proved the amelioration of pancreatic injury by alphapinene and biochemical parameters proved anti-inflammatory and antioxidant property of alpha-pinene.

Role of NO-ergic system of the he nucleus accumbens in metabolic disturbances under acute stress
Introduction: The aim of the study was to evaluate the involvement of nitricergic system within the shell part of the nucleus accumbens (NAc) by injection of L-arginine, a nitric oxide precursor, and L NAME, a nitric oxide synthase inhibitor in the metabolic disturbances induced by acute stress in the male rat. Materials and Methods: Male Wistar rats were cannulated unilaterally in the left par...

Background: Role of nitric oxide (NO) in morphine-induced conditioned place preference (CPP) has already been proposed in the rat medial septum (MS), but no molecular evidence has been provided to clear this fact. Methods: Effects of intraseptal injections of L-arginine and/or NG-nitro-L-arginine methyl ester (L-NAME) on morphine place conditioning in Wistar rats were examined. Morphine (2.5-7....

Introduction: Intra-hippocampal CA1 injections of L-arginine, a nitric oxide precursor and NG-Nitro-L-arginine Methyl Ester (L-NAME), a nitric oxide synthase inhibitor, on morphine-induced antinociception in rat formalin test were investigated. Method: To induce inflammation pain, male Wistar rats received subcutaneous (s.c.) injections of formalin (50 μl at 2.5%) once prior to testing. Morphin...
متن کاملThe effect of intraaccumbal injection of L-arginine and L-NAME on induction and removal of conditioned place preference in rat
Nucleus accumbens (Nac) has been considered as a center for the induction of drug dependence. Since a high concentration of the enzyme, nitric oxide synthase (NOS) has been found in the Nac, and this fact that the role of nitric oxide (NO) in acquisition and expression of drug dependence has become clear in recent years, therefore in this study the effects of intraaccumbal injections of L-argin...
