| چکیده | ||
| فاکتور رشد شبه انسولین-یک (IGF-I) در ماهیان استخوانی دارای نقش مهمی در تنظیم رشد و تولید مثل از طریق تاثیر در متابولیسم, تقسیم سلولی، تخمک‌سازی، رسیدگی نهایی اووسیت‌ها و فعالیت‌های ترشحی است. این سیستم توسط چندین هورمون و شرایط متابولیکی تنظیم می‌گردد. در این مطالعه مقادیر سرمی IGF-I تیروکسین و کورتیزول در دو گروه از مولدین صید شده از دریا و رودخانه در طی مراحل انتهایی رسیدگی جنسی آنها و در سه مرحله رسیدگی جنسی (زمان صید, تزریق هیپوفیز و تکثیر مصنوعی) مورد بررسی قرار گرفت. از یک سیستم رادیوایمونوآسی نامتجانس با استفاده از پادتن پلی‌کلنال تهیه شده بر علیه IGF-I انسانی و IGF-I انسانی به عنوان پادگن، مقادیر سرمی IGF-I اندازه‌گیری شد. غلظت هورمون‌های تیروکسین و کورتیزول نیز با استفاده از روش رادیوایمونوآسی تعیین گردیدند. نتایج آزمایش تفاوت‌های معنی‌داری را در مقادیر سرمی هورمون‌های مورد بررسی بین دو گروه از مولدین، نشان نداد (05/0 <P). در هر دو گروه از مولدین، میانگین غلظت سرمی IGF-I در مراحل تزریق هیپوفیز و تکثیر مصنوعی بطور معنی‌دار بیش از مرحله صید بود (05/0 >P). در مولدین رودخانه‌ای مقادیر سرمی تیروکسین در زمان تکثیر مصنوعی بیش از دو مرحله قبل بود ولی این تفاوت در مولدین دریایی مشاهده نشد(05/0 >P). مقادیر کورتیزول سرم در مراحل نمونه‌برداری بجز مرحله تزریق هیپوفیز در مولدین دریایی تفاوت معنی داری را نشان نداد(05/0 <P). نتایج این تحقیق نشان می‌دهد که IGF-I سرمی دارای نقشی در طی مراحل انتهایی رسیدگی جنسی تاس‌ماهی ایرانی است، به علاوه ارتباطی بین مقادیر سرمی IGF-I با هورمون‌های تیروکسین و کورتیزول در هر دو گروه از مولدین وجود ندارد. | ||

| چکیده [English] | ||
| In teleosts the insulin-like growth factor-I, a member of IGF system, play an important role in the control of growth and reproduction including metabolism, cell division, oogenesis, final oocyte maturation and secretory activity. This system is controlled by several hormones and metabolic status. Serum IGF-I, thyroxine (T4) and cortisol levels were studied in two female brood stocks (caught from sea and from river during their up stream migration) during their late stage of sex maturation. Blood samples were taken from 6 individual in each brood stocks, and at three ovarian developmental stages (brood stock capture, pituitary injection and artificial propagation) based on their polarization index (IP). A heterologous radioimmunoassay system which used polyclonal anti-human IGF-I and human IGF-I as antigen, was used for IGF-I serum measurements. T4 and cortisol concentrations were also measured by radioimmunoassay. Our results did not show significantly differences in IGF-I, T4 and cortisol levels between two brood stocks. However, in both brood stocks the mean IGF-I serum concentrations were higher in the second and third sampling stages than the first one (p<0.05). In the river brood stock, T4 serum level was significantly higher during ovulation than the second stage, but it was not observed in sea brood stock (p< 0.05). Cortisol serum levels had not showed significantly differences between three sampling stages in both brood stocks, except at second sampling in sea water brood. These results could provide evidence for a possible role of IGF-I during final oocyte maturation of Persian sturgeon. The up regulation of serum IGF-I may have a role in the resumption of meiotic arrest during late stage of sex maturation. However, we could not found any relationship between IGF-I, T4 and cortisol serum levels in both brood stocks. | ||
