چکیده مقاله:

Background: The authors today know the complication Ovarian Polycystic that is a cause of infertility. Drugs including morphine have been known to play effective role in the incidence of this complication, too. Naloxone is known a competitive inhibitor of morphine which connect with mu receptor at the central level, and the environment that has antagonistic effect on morphine. This study examined the interaction of morphine / naloxone in central hypothalamus of Wistar rats.Methods: Experimental animals were virgin female Wistar rats with Weight range of 250-200 g /. Morphine (0.001 to 0.4 micrograms / rat) was injected into ventro-medial hypothalamus of rat (nucleus coordinates: AP: -1.96). Naloxone (0.1 to 0.4 micrograms / rat) was injected alone or pre-microinjected. In the process of naloxone pre-injection, it (0.1 to 0.4 Micrograms / rat) was administered prior to morphine (0.4 micrograms / rat). The control group received only saline. After completion of the experiments, the animals were anesthetized and after surgery, the ovaries were collected and investigated.Result: Naloxone intervention in group receiving naloxone in presence of morphine significantly reduced the number of cysts in the ovaries of rats. Ovarian aspect in the naloxone groups was as the control group.Conclusion: According to the results the interaction of morphine with opioid receptors in the nucleus of the hypothalamus is necessary in the development of polycystic ovaries, the complication that is stopped by inhibiting of morphine-receptor interaction due to naloxone intervention.
