Abstract:
Objective To discuss the effects of utero placental ischemia on the body and nervous system development in fetal rats Methods By clamping the unilateral uterine artery of the rat, we produced a utero placental ischemia model The opposite uterus of the rat with normal uterine artery supply served as control We compared the body weight, weight of brain, and the expression of growth associated protein 43(GAP 43) mRNA in cerebral tissue by RT PCR in the 13 day (group 1) and 17 day(group 2) old fetal rats respectively Results The body weight and weight of brain in group 1 were 3 2 g and 0 16 g respectively, significantly lower than those of control 1 of 3 6 g and 0 18 g respectively ( P 0 05) However, GAP 43 mRNA in cerebral tissue of the group 2 (1 06) was significantly decreased compared with that of its control(1 21 )( P
