چکیده

مقدمه و هدف: مرفین احتمالاً با تغییر سطح گلوتامات در هسته های هیپوتالاموسی باعث القایPCOS) Polycystic ovary syndrome )  می‏شود. در این پژوهش اثر تداخلی دوزهای پایین کتامین با PCOS ناشی از مرفین بررسی شد.
مواد و روش ها: 48 سر موش ماده نژاد ویستار باکره در محدوده وزنی 220-250 گرم انتخاب و به طور تصادفی در هشت گروه دسته بندی شدند. گروه اول مرفین (5 میلی گرم بر کیلوگرم) به صورت داخل صفاقی دریافت کرد. گروههای دوم تا چهارم کتامین دریافت کردند (1، 2، 4 میلی گرم بر کیلوگرم). در گروههای 5 تا 7، کتامین (1، 2، 4 میلی گرم بر کیلوگرم) 20 دقیقه جلوتر از مرفین (5 میلی گرم بر کیلوگرم) تزریق شد. گروه کنترل فقط سالین (1 میلی لیتر بر کیلوگرم) گرفت. پس از 48 ساعت، نمونه‏های خون و سرم برای تعیین سطوح هورمونی تهیه گردید و تخمدان و رحم حیوانات بیومتری و به کمک هماتوکسیلین-ائوزین رنگ آمیزی شدند. تجزیه و تحلیل آماری با آنالیز واریانس (ANOVA) تحت 05/0=α انجام شد.
نتایج: مرفین و کتامین تنها موجب القای PCOS شدند. با این حال، تجویز کتامین قبل از مرفین، باعث کاهش معنی دار تعداد کیست در تخمدان گردید. همچنین در گروه دریافت‏کننده مرفین، افزایش نسبی قطر رحم مشاهده شد که این امر به دلیل پیش تیمار کتامین متوقف شد. این اثرات با کاهش سطح FSH و تغییر مقادیر استروژن و پرولاکتین ارتباط نشان داد.
نتیجه‌گیری: اثر تداخلی کتامین با مرفین کاملاً به تغییر در سطح هورمون گنادوتروپین بستگی دارد.

چکیده [English]

Background and Objective: Morphine can induce PCOS (Polycystic ovary syndrome) probably by changing glutamate level at the hypothalamic nuclei. This study used low doses of ketamine to survey the interaction of ketamine with morphine-induced PCOS.
Materials and Methods: 48 female Wistar rats were selected as virgins in the weight range of 220-250 g, and categorized randomly into eight groups. The first group received morphine (5 mg/kg) intraperitoneally. The second to fourth groups received ketamine (1, 2, and 4 mg/kg). In groups 5 to 7, the ketamine (1, 2, and 4 mg/kg) was pre-injected to morphine (5 mg/kg) over a period of 20 min. Control group received only saline (1 ml/kg). After 48 h, the blood and serum specimens were provided to record hormone levels, and the animals’ ovaries and uteri were biometrically examined and stained by H & E. Statistical analysis was performed by analysis of variance (ANOVA) under α=0.05.
Results: The morphine as well as single ketamine induced the PCOS. However, taking ketamine prior to morphine caused a meaningful reduction in the number of cysts in the ovary. There was also a relative increase in uterine diameter in the group receiving morphine, which was stopped due to ketamine pre-treatment. These effects showed correlation with decreased levels of FSH, and change in estrogen, and prolactin amounts.
Conclusion: The interference effect of ketamine with morphine is completely dependent on changes in gonadotropin level.
