摘要(Abstract)：
观察了海狗油脂肪乳对大鼠妊娠晚期、分娩期、哺乳期及胚胎和胎仔出生后生长发育、学习能力以及生殖能力的影响.于大鼠妊娠D15至哺乳D21,连续皮下注射给予250、500和1000mg·kg-1剂量的海狗油脂肪乳,同时设0.9%氯化钠注射液为对照组,观察各组大鼠和胎仔的生长、发育、生殖能力等项指标.结果表明:给药后F0代母鼠体重增长明显减慢,摄食量显著减少,未见生殖、胚胎毒性反应;F1代仔鼠的出生体重和哺乳期体重增长减慢,生理达标、新生反射等发育迟缓;停药后F1代大鼠的体重增长、摄食量、脏器系数、同笼交配率、妊娠率及胚胎发育全过程未见明显生殖、发育等毒性变化.由此结论,海狗油脂肪乳可使母鼠和F1代仔鼠体重增长缓慢,生理发育迟缓,但不影响F1代仔鼠器官发育、生殖能力以及停药后体重增长和摄食量.
