چکیده

پیشینه مطالعه و هدف: اعتیاد به تریاک در جامعه بسیار ایرانی شایع است‌. در طی دو دهه گذشته، در کنگره 60 که یک سازمان غیر دولتی است، روش درمان تدریجی تریاک (DST) که مرتبط با کلاس‌های گروهی درمان‌های روانشناختی است اجرا شده است‌. اثر بخشی متد کاهش تدریجی تریاک، تایید شده است‌. اما مکانیسم‌های مولکولی این روش درمان اعتیاد به طور کلی روشن نشده است‌. ژن BDNF فاکتور نوروتروفیک مشتق گرفته از مغز است که با چندین مکانیسم مولکولی مغز شامل حافظه مرتبط است.
روش مطالعه: ابتدا نمونه‌های سلول‌های خون از 21 نفر از بیماران مراجعه کننده به مرکز ترک اعتیاد کنگره شصت قبل و بعد از 5 ماه درمان تهیه شد. RNA استخراج شده از هر نمونه به وسیله روش RT به cDNA تبدیل و با استفاده از آغازگرهای اختصاصی برای ژن BDNF، تکثیر گردید؛ همچنین تولید درون سلولی پروتئین BDNF به وسیله روش وسترن بلات مورد بررسی قرار گرفت.
نتایج: کاهش قابل توجه بیان ژن BDNF در دربیماران معتاد در مقابل افراد سالم نشان داده شد‌. همچنین به طور قابل ملاحظه‌ای افزایش بیان ژن BDNF در بیماران بعداز 5 ماه دوره درمانی مشاهده شد (01/0>p ). بنابراین سوء مصرف مواد و روش درمان تدریجی بر روی بیان BDNF اثر ‌می‌گذارد‌.
نتیجه‌گیری: مطالعات حاضر می‌تواند به فهم بهتر مکانیسم‌های نورولوژیکی و مولکولی تریاک و روش درمان تدریجی کمک نماید‌. همچنین BDNF به عنوان مارکرهای بالقوه برای آزمایش و اثر بخشی انواع مختلف درمان اعتیاد باشد.‌

چکیده [English]

Introduction and Aim: Opium addiction is one of the most prevalent addiction in Iranian society. Throughout the last two decades, congress 60; a nongovernmental organization; has been operated a taper off treatment of opium associated with a package of psychological treatment group classes. Although the effectiveness of the taper off method in opium addiction has been verified, molecular mechanisms involved in this treatment have not explained. BDNF gene is a brain-derived neurotrophic factor that is associated with numerous molecular mechanisms of the brain including memory.
Methods: In this research, peripheral blood samples from 21 patients were collected from Congress 60. RNA was extracted from each sample, reverse transcribed and amplified via RT-PCR technique, utilizing specific primers for BDNF. The production of BDNF protein was also analyzed employing the western blotting technique.
Results: Our results exhibited considerable down expression of BDNF in addict persons vs. non-psychiatric persons (p < /em><0.01). Furthermore, BDNF expression levels in addicts increased significantly after the therapy period. Findings showed the effect of opium abuse and taper off treatment on the expression of BDNF.
Conclusion: The present study could help to a better understanding of molecular and neurological mechanisms of opium and taper off treatment. Additionally, BDNF level detection could be a potential marker for screening the effectiveness of various types of addiction treatment.
