Obstruction of the common bile duct is associated with hepatic paranchymal damage and increased susceptibility to subsequent bacterial infections. Erythropoietin has antiinflammatory and cytoprotective effects and it induces antiinflammatory cytokines and suppresses the production of proinflammatory cytokines. In this study, we aimed to investigate the effect of Erythropoietin on bacterial translocation, inflammation and tissue damage in rats with obstructive jaundice.
Thirty-two Wistar albino rats (200-250 g) were divided into 4 groups as follows: Group 1 (Sham); only hepatoduodenal ligament dissection, Group 2 (Erythropoietin); hepatoduodenal ligament dissection and given 500 IU/kg Erythropoietin subcutaneously, Group 3 (Obstructive jaundice); complete hepatoduodenal ligament ligation, Group 4 (Obstructive jaundice + Erythropoietin); complete hepatoduodenal ligament ligation and given 500 IU/kg Erythropoietin subcutaneously. After 7 days, the rats were sacrificed by taking blood from the heart for biochemical analyses. Peritoneal swab culture, liver, mesenteric lymph nodes, spleen and ileum were collected for microbiological and histopathological examinations.
Erythropoietin reduced the secretion of inflammatory cytokines, oxidative damage and bacterial translocation, prevent the formation of inflammatory changes in intestine and liver after obstructive jaundice.
The treatment of EPO in rats with OJ reduces bacterial translocation, inflammation and tissue damage.
胆总管梗阻与肝实质损伤以及随后细菌感染易感性增加有关。促红细胞生成素具有抗炎和细胞保护作用,它可诱导抗炎细胞因子并抑制促炎细胞因子的产生。在本研究中,我们旨在探讨促红细胞生成素对梗阻性黄疸大鼠细菌移位、炎症和组织损伤的影响。
32只Wistar白化大鼠(200 - 250克)分为以下4组:第1组(假手术组);仅进行肝十二指肠韧带解剖,第2组(促红细胞生成素组);进行肝十二指肠韧带解剖并皮下注射500 IU/千克促红细胞生成素,第3组(梗阻性黄疸组);完全结扎肝十二指肠韧带,第4组(梗阻性黄疸 + 促红细胞生成素组);完全结扎肝十二指肠韧带并皮下注射500 IU/千克促红细胞生成素。7天后,通过心脏采血处死大鼠进行生化分析。采集腹腔拭子培养物、肝脏、肠系膜淋巴结、脾脏和回肠进行微生物学和组织病理学检查。
促红细胞生成素减少了炎性细胞因子的分泌、氧化损伤和细菌移位,防止了梗阻性黄疸后肠道和肝脏炎症变化的形成。
