TY - JOUR ID - 23715 TI - یافته های هیستوپاتولوژیک در مغز جنین های سقط شده و ارتباط احتمالی آنها با عوامل ایجاد کننده سقط جنین در گوسفند، بز و گاو JO - مجله تحقیقات دامپزشکی (Journal of Veterinary Research) JA - JVR LA - fa SN - 2008-2525 AU - صیفوری, پروانه AU - ساسانی, فرهنگ AU - نجفی, جمال AD - گروه پاتوبیولوژی ،دانشکده دامپزشکی دانشگاه تهران AD - گروه پاتوبیولوژی مرکز تشخیص سازمان دامپزشکی کشور Y1 - 2008 PY - 2008 VL - 63 IS - 3 SP - 177 EP - 181 DO - N2 - The histopathological findings include as following: Gliosis (52%), Neuronal necrosis (37%), Perivascular cuffing (5.4%), hyperemia and hemorrhage in cerebral tissues (32.9%), hyperemia and hemorrhage in meninge(19.2%), prevascullar and preneuronal edema (52%), Meningial edema (16.4%), Vacuole in neurons (2.7%), Vacuoleinneuropil( 8.2% ),protozoal cyct(5.4%). Frequency of fetal brain lesions consists of: meningitis (9.6%), encephalitis (50.7%), (non suppurative encephalitis 38.3%, suppurative encephalitis 12.3%), meningoencephalitis (8.2%), Encephalomalacia (1.4%), congenital anomalies (6.8% )(hydrocephaly andhydranencephaly). Non purulent encephalitis was the most common lesion in fetal brains that could be caused by viral and protozoal agents. 71 % of non-supporative encephalitis consisted of multifocal necrotic encephalitis which are mostly caused by protozoa. The etiology of abortion should be considered in future studies. UR - https://jvr.ut.ac.ir/article_23715.html L1 - https://jvr.ut.ac.ir/article_23715_1d4eadcd03aba5a3b10022fed88fbde3.pdf ER -
