ABSTRACT
3,4- Methylenedioxymethamphetamine [MDMA or "Ecstasy"] is a psychoactive and hallucinogenic drug of abuse. MDMA has been shown to produce neurotoxicity both in animals and humans. Recently, the vasodilator drugs such as pentoxifylline is one of the new strategies which have been considered as neuroprotector. In this study effect of pentoxifylline on bcl-2 gene expression changes in hippocampus of rat following long- term use of ecstasy was investigated. 30 male Wistar rats weighing 250-300g were randomly divided into 5 groups control [normal], sham [MDMA injection], experimental 1[MDMA and then PTX injections], experimental 2[PTX injection and after 1 week, MDMA injection] and vehicle [saline injection] groups. All drugs were injected intraperitoneally. Two weeks later, the hippocampi were removed for studying the changes in bcl-2 gene expression. We used quantitative real time PCR for detection of bcl-2 gene expression in treated groups and then compared them to control samples. The results showed the gene dosage ratio of 0.49, 0.78 and 1.17 for sham, experimental 1 and experimental 2 groups, respectively. The results also showed the bcl-2gene expression declined in sham group as compared to the experimental groups. Furthermore, we observed a significant difference in the bcl-2 gene expression between sham and experimental 2 groups. We conclude that quantitative real time PCR could be used as a direct method for the detection of bcl-2 gene expression in tested and normal samples
