چکیده مقاله :
Effect of ethanol consumption on fear response in human and conventional animal models (rodents) is controversial. The present study aimed to investigate the effect of ethanol administration on fearfulness in poultry as an alternative animal model.Being a reliable measure in avian species, tonic immobility was used to evaluate the fear response in 60 roosters orally administered with ethanol. Duration of tonic immobility was higher in alcohol-exposed birds compared to the control birds (P<0.05), suggesting that dosing the roosters with ethanol was associated with an increased fear response which makes poultry as a plausible alternative model in behavioral studies.
آثار مصرف اتانول بر پاسخ ترس در انسان و مدل‌های حیوانی متداول (همچون جوندگان) بحث برانگیز است. هدف از این پژوهش بررسی اثر دوز مصرفی اتانول بر پاسخ ترس ماکیان به عنوان مدل حیوانی جایگزین بود. برای پاسخ ترس در ماکیان، مدل بی‌تحرکی تونیک در 60 خروس تیمار شده با اتانول استفاده شد. مدت زمان بی‌تحرکی تونیک در پرنده‌های تیمار شده با الکل در مقایسه با گروه شاهد به طور معنی‌دار بیشتر بود (05/0>P)، که مشخص می‌کند که مقدار دوز خورانده شده اتانول به خروس‌ها با پاسخ ترس همبستگی مثبتی داشت که این موضوع ماکیان را به عنوان مدل مناسب جایگزین برای مطالعات رفتاری معرفی می‌کند.
