چکیده
تأثیر پرتوگیری مزمن بر ساکنین مناطق با پرتوزایی طبیعی بالا در شهر رامسر، با استفاده از روش سیتوژنتیک سنجش هستک­های متوقف شده در مرحله سیتوکینز و مقایسه­ی نتایج میان دو گروه مورد مطالعه و کنترل، مورد بررسی قرار گرفت. نتایج نشان داد اختلاف معنی­داری (001/0< P) در میانگین فرکانس هستک­های شمارش شده در لنفوسیت­های خون محیطی گروه مورد مطالعه (ساکن در منطقه­ی با پرتوزایی طبیعی بالای شهر رامسر) و گروه کنترل (ساکن در شهر تنکابن) وجود دارد. هم­چنین، بعد از پرتودهی نمونه­ها، گروه کنترل، افزایش بیش­تری را در فرکانس هستک­ها نسبت به گروه مورد مطالعه نشان داد و این امر، شاهدی بر وجود پدیده پاسخ تطبیقی پرتوی، در ساکنین مناطق با پرتوزایی طبیعی بالا در شهر رامسر می­باشد. همبستگی میان فرکانس هستک­ها و سن، در گروه کنترل بیش­تر از گروه مورد مطالعه مشاهده شد.

چکیده English

The effect of chronic exposure on Ramsar HBNRAs inhabitants' health was studied using Cytokinesis Blocked Micronucleus (CBMN) Assay. The results showed a significant difference (P <0.001) in the mean frequency of micronucleus of the study group, or resident in Ramsar HBNRAs, and the control group, which were selected from Tonekabon, a city near Ramsar. Significant differences (P <0.001) were observed between the mean micronucleus frequency after irradiation of blood samples, which means that after irradiation of blood samples, the control group showed a higher increase in micronuclei frequency than the study group that can be as a result of the existence of a radio adaptive response in Ramsar HBNRAs. The correlation was observed between the frequency of micronucleus and age in control groups but was not obtained for the study group.
