fa بررسی اثر مصرف دوز‌های پایین الکل بر کبد جنین موش صحرایی- مطالعه‌ی بافت‌شناسی کارآزمایی بالینی Clinical Trials <p style="text-align: justify;"><strong><em>Background and Objective:</em></strong> Alcohol is a teratogenic agent for humans and can easily pass through the placenta. Low doses of alcohol are commonly found in alcoholic drinks, therefore the purpose of this study was to investigate the histological changes of fetal rat livers influenced by low doses of alcohol consumption.</p> <p style="text-align: justify;"><strong><em>Materials and Methods:</em></strong> In this experimental study, pregnant female rats were divided into a control group and three experimental groups which were on a diet of 5%, 10% and 20% of alcohol in their drinking water. The specified doses of alcohol were delivered from the 8^thday of pregnancy until the 20^th day. On the 21^st day of pregnancy, the fetuses were surgically removed from the mother&#39;s uterus and the livers of the fetuses were removed with the help of a stereo microscope. Following fixing, processing and sectioning, the fetal livers were stained using H&E and were studied under a light microscope. Data were analyzed by SPSS software and ANOVA.</p> <p style="text-align: justify;"><strong><em>Results:</em></strong> Alcohol doses of 10% and 20% significantly increased histopathological liver factors (p<0.001). But a 5% dose of alcohol didn&#39;t have a significant effect on liver histology.</p> <p style="text-align: justify;"><strong><em>Conclusion:</em></strong> Alcohol usage during pregnancy, even at low doses, may lead to pathologic changes in the liver of a developing rat fetus. A 5% dose of alcohol does not lead to significant pathologic changes in the histology of the fetal rat liver, while doses of 10% and 20% of alcohol significantly increases inflammatory factors in histological studies.</p> <p></p><p></p> Alcohol, Pregnancy, Fetus, Liver, Histology 29 40 http://journal.zums.ac.ir/browse.php?a_code=A-10-4-1021&slc_lang=fa&sid=1 Maziar Bahrami مازیار بهرامی 5200319475328460053255 5200319475328460053255 Yes Dept. of Biology, Faculty of Biological Sciences, Islamic Azad University, North Tehran Branch, Tehran, Iran دانشکده‌ی علوم زیستی، دانشگاه آزاد اسلامی واحد تهران شمال، تهران Mehrdad Ghorbanlou مهرداد قربانلو 5200319475328460053256 5200319475328460053256 No Dept. of Anatomy, Faculty of Medicine, Zanjan University of Medical Sciences, Zanjan, Iran دانشکده‌ی پزشکی، دانشگاه علوم‌پزشکی زنجان، زنجان Ahmad Farrokhi احمد فرخی 5200319475328460053257 5200319475328460053257 No Dept. of Anatomy, Faculty of Medicine, Zanjan University of Medical Sciences, Zanjan, Iran دانشکده‌ی پزشکی، دانشگاه علوم‌پزشکی زنجان، زنجان Reza Nejatbakhsh رضا نجات بخش 5200319475328460053258 5200319475328460053258 No Dept. of Anatomy, Faculty of Medicine, Zanjan University of Medical Sciences, Zanjan, Iran دانشکده‌ی پزشکی، دانشگاه علوم پزشکی زنجان، زنجان
