Abstract:
Objective To study whether hyperthermia and ionizing radiation could produce combined effects on the neurobehaviors of neonatal rats.Methods These rats who were pregnant for 8 or 9 days received respectively total body irradiation by 60Co-rays .When the rats were pregnant for 10 days,the temperature of rat anus was kept at (37?0.5) ℃,(41?0.5) ℃,(42?0.5) ℃,respectively in warming boxes and lasted for 2,3,4,5 minutes.The neurobehaviors of neonatal rats were observed.Results In contrast to control group and 37 ℃group ,when pregnant rats were exposed to high temperature.the neonate rats were delayed for the appearance of four physiologic markers,the age of acquisition for four reflexes and the time of learning and memory(P
