Lipopolysaccharides (LPSs) are a component of certain types of bacteria and can induce an inflammatory response in the body, including in the pancreas. Cannabidiol (CBD), a nonpsychoactive compound found in cannabis, has been shown to have anti-inflammatory effects and may offer potential therapeutic benefits for conditions involving inflammation and damage. The aim of this study was to investigate any potential preventative effects of CBD on experimental LPS-induced pancreatic pathology in rats. Thirty-two rats were randomly divided into four groups as control, LPS (5 mg/kg, intraperitoneally [i.p.]), LPS+CBD, and CBD (5 mg/kg, i.p.) groups. Six hours after administering LPS, the rats were euthanized, and blood and pancreatic tissue samples were taken for biochemical, polymerase chain reaction (PCR), histopathological, and immunohistochemical examinations. The results indicated that LPS decreased serum glucose levels and increased lipase levels. It also caused severe hyperemia, increased vacuolization in endocrine cells, edema, and slight inflammatory cell infiltrations at the histopathological examination. Insulin and amylin expressions decreased during immunohistochemical analyses. At the PCR analysis, Silent Information Regulator 2 homolog 1 and peroxisome proliferator-activated receptor gamma coactivator-1 alpha expressions decreased and tumor protein p53 expressions increased in the LPS group. CBD improved the biochemical, PCR, histopathological, and immunohistochemical results. The findings of the current investigation demonstrated that LPS damages both the endocrine and exocrine pancreas. However, CBD demonstrated marked ameliorative effects in the pancreas in LPS induced rat model pancreatitis.
脂多糖 (LPSs) 是某些类型细菌的组成部分,可在体内引起炎症反应,包括胰腺。大麻中的非精神活性化合物大麻二酚 (CBD) 已被证明具有抗炎作用,并可能为涉及炎症和损伤的疾病提供潜在的治疗益处。本研究旨在探讨 CBD 对实验性 LPS 诱导的大鼠胰腺病变的潜在预防作用。
32 只大鼠随机分为对照组、LPS(5mg/kg,腹腔内 [i.p.])组、LPS+CBD 组和 CBD(5mg/kg,i.p.)组。给予 LPS 后 6 小时处死大鼠,采集血液和胰腺组织样本进行生化、聚合酶链反应(PCR)、组织病理学和免疫组织化学检查。
结果表明,LPS 降低了血清葡萄糖水平并增加了脂肪酶水平。它还导致严重的充血、内分泌细胞空泡化增加、水肿和轻微的炎症细胞浸润。免疫组织化学分析显示胰岛素和胰淀素表达减少。在 PCR 分析中,沉默信息调节因子 2 同源物 1 和过氧化物酶体增殖物激活受体γ共激活物-1α的表达减少,肿瘤蛋白 p53 的表达增加。CBD 改善了生化、PCR、组织病理学和免疫组织化学结果。
本研究结果表明,LPS 损伤了胰腺的内分泌和外分泌功能。然而,CBD 在 LPS 诱导的大鼠胰腺炎模型中对胰腺表现出明显的改善作用。
