Abstract

BACKGROUND: The prelimbic area (PL) of the prefrontal cortex is susceptible to abnormal developmental stimuli that raises the risk of addiction. Glutamate receptors play a key role in opiate reinforcement and reward functions in this area. Therefore, we examined the effect of the DL-2-amino-5-phosphonopentanoic acid (AP5), as N-methyl-D-aspartate (NMDA) receptor antagonist into the PL on the phases of conditioned place preference (CPP) induced by morphine.METHODS: Male Wistar rats were divided into 12 groups (3 surgical groups for each dose of morphine in any phase of CPP) and anaesthetized with chloral hydrate. Cannula was implanted into the PL and the AP5 was injected into this area and morphine-induced CPP was investigated. Data were processed with the commercially available SPSS 22 software using one-way ANOVA and Tukey's test. p<0.05 were considered statistically significant.RESULTS: Our findings indicated, morphine in doses of 2.5 to 10 mg/kg induced CPP. Microinjection of various doses of the AP5 into the PL before the administration of the effective dose of morphine significantly reduced place preference in the acquisition and the expression phases of the CPP test compared to the sham group (p<0.001). In another set of our experiments was seen that, different doses of the AP5 with the ineffective dose of morphine only reduced the expression phase of the CPP (p<0.001) while, produced neither preference nor aversion effect on the acquisition phase (p=0.147).CONCLUSION: It seems that the glutamate NMDA receptors in the PL through memory formation and morphine-related reward signals play a critical role in addiction process during morphine-induced CPP.KEYWORDS: N-methyl-aspartate, morphine, glutamate receptor, prefrontal cortex, reward

Abstract

BACKGROUND: Busulfan, a chemotherapeutic drug, is an alkylating antineoplastic agent that belongs to the class of alkyl sulfonates and has some side effects on fertility. This research was aimed to investigate the effects of busulfan on testicular tissue and serum levels of anti-Mullerian hormone (AMH) and testosterone in adult mice.METHODS: Eighteen adult male Balb/C mice were collected randomly and were assigned in three groups including; control, azoospermia and spontaneous recovery. The groups, except for control group, received two injections of busulfan (10 mg/kg) intraperitoneally with 21-days interval in order to induce azoospermia. Thirty-five and 140 days after the last injection, the effects of busulfan on testicular tissue were evaluated by histologic, histomorphometric and hormonal changes. AMH and testosterone were measured by enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA) kits, respectively.RESULTS: Hormonal analyses showed no significant differences in AMH and testosterone serum levels. Histologic and histomorphometric evaluation showed disrupted spermatogenesis in azoospermia group, and restoration of spermatogenesis spontaneously in spontaneous recovery group.CONCLUSION: Busulfan at doses was used had no effect on AMH and testosterone serum levels. Busulfan can also induce azoospermia on a temporary basis however, in long term, spontaneous recovery can occur. The results indicated that some side effects are reversible and may depend on the dose applied.KEYWORDS: Busulfan, anti-Mullerian hormone, testosterone, mouse, testis
