مقدمه

هدف مطالعه حاضر بررسی اثر عصاره درمنه ایرانی بر تشنج و مشکلات رفتاری ناشی از PTZ در موش‌های سوری بود.

مواد و روش‌­ها

70 موش به 7 گروه کنترل (نرمال‌سالین)، مدل (PTZ در دوز 35 میلی‌گرم بر کیلوگرم با فواصل 48 ساعت و در روز دهم در دوز 60 میلی‌گرم بر کیلوگرم)، گروه‌های مداخله (PTZ با فواصل 48 ساعت و عصاره در دوزهای 100، 200 و 400 میلی‌گرم بر کیلوگرم بصورت روزانه) و گروه فلومازنیل و دیازپام ( PTZ، عصاره در دوز 400 میلی‌گرم بر کیلوگرم و فلومازنیل یا دیازپام در روز دهم) تقسیم شدند. آزمون‌های معلق ماندن دم (TST)، روتارود، مازبعلاوه‌ای مرتفع (EPM) و صفحه باز جهت ارزیابی اختلالات رفتاری استفاده شدند.

یافته‌­ها

تیمار موش‌های کیندلینگ شده توسط PTZ با عصاره درمنه و دیازپام سبب افزایش معنی‌دار زمان تاخیر شروع تشنج شد. در موش‌های کیندلینگ شده توسط PTZ کاهش معنی‌دار دفعات ورود به مرکز در آزمون صفحه باز و افزایش معنی‌دار مدت زمان بی‌حرکتی در آزمون معلق ماندن از دم مشاهده شد و تیمار توسط دوزهای مختلف عصاره درمنه سبب بهبود جزئی و غیرمعنی‌دار آن‌ها شد. PTZ همچنین سبب افزایش دفعات ورود و مدت زمان سپری شده در بازوی بسته و کاهش دفعات ورود و مدت زمان سپری شده در بازوی باز EPM شد و عصاره درمنه سبب بهبود جزئی و غیرمعنی‌دار آن شد.

نتیجه­‌گیری

دوزهای مختلف عصاره گیاه درمنه ایرانی در برابر تشنج و افسردگی و اضطراب ناشی از PTZ در موش‌های سوری اثرات معنی داری نداشته است و پیشنهاد می‌شود مطالعات آتی بر ترکیبات گیاه تمرکز کنند.

Introduction

The aim of this study was to investigate the effect of Artemisia persica (AP) extract on seizure and behavioral problems induced by PTZ in male rats.

Materials and Methods

70 male mice were randomly divided into the seven groups including control (normal saline), model (PTZ at a dose of 35 mg/kg with 48h intervals and at 60 mg/kg on the 10th day), intervention groups (PTZ with 48h intervals and extract at doses of 100, 200 and 400 mg/kg daily) and flumazenil and diazepam groups (PTZ, extract at 400 mg/kg and flumazenil or diazepam on the 10th day). Tail suspension test (TST), rotarod, elevated plus maze (EPM) and open -filed were used to evaluate behavioral disorders.

Results

Treatment of PTZ-kindled mice with Artemisia persica extract and diazepam caused a significant increase in a seizure onset time (P<0.05). A significant reduction in the center square entrance in the open-field test and a significant increase in the duration of immobility time in the TST were observed in the PTZ-kindled mice (P <0.05). Treatment with different doses of Artemisia persicaextract resulted in minor and non-significant improvement of these parameters. PTZ also increased the number of entries and the time elapsed in the closed arm and reduced the number of entries and the time elapsed in the open arm of the EPM. The Artemisia persicaextract caused a minor and non-significant improvement.

Conclusion

Different doses of Artemisia persica extract showed no significant effect against seizure, depression, and anxiety caused by PTZ in mice. It is suggested that future studies focus on plant compounds.​
