OBJECTIVE(S): 3,4-Methylenedioxymethamphetamine (MDMA) is one of the most popular drugs of abuse in the world with hallucinogenic properties that has been shown to induce apoptosis in liver cells. The present study aimed to investigate the effects of pentoxifylline (PTX) on liver damage induced by acute administration of MDMA in Wistar rat.
MATERIALS AND METHODS
Animals were administered with saline or MDMA (7.5 mg/kg, IP) 3 times with 2 hr intervals. PTX (200 mg kg, IP), was administered simultaneously with last injection of MDMA in experimental group.
RESULTS
The concomitant administration of pentoxifylline and MDMA decreased liver injury including apoptosis, fibrosis and hepatocytes damages.
CONCLUSION
Our results showed for the first time that PTX treatment diminishes the extent of apoptosis and fibrosis caused by MDMA in rat liver.
目的
3,4-亚甲二氧基甲基苯丙胺（MDMA）是世界上最受欢迎的滥用药物之一，具有致幻特性，已被证明可诱导肝细胞凋亡。本研究旨在探讨己酮可可碱（PTX）对 Wistar 大鼠急性 MDMA 给药引起的肝损伤的影响。
材料和方法
动物给予生理盐水或 MDMA（7.5mg/kg，IP），3 次，间隔 2 小时。PTX（200mgkg，IP）在实验组最后一次 MDMA 注射时同时给药。
结果
同时给予己酮可可碱和 MDMA 可减少肝损伤，包括凋亡、纤维化和肝细胞损伤。
结论
我们的结果首次表明，PTX 治疗可减轻 MDMA 引起的大鼠肝损伤中的细胞凋亡和纤维化程度。
