Abstract

Introduction: Previous studies have shown that MORPHINE administration could inhibit neural tube DEVELOPMENT in rat embryos and produce behavioral defects in human and animals. In the present study, the effects of maternal MORPHINE consumption on embryonic NEURAL PLATE DEVELOPMENT in Wistar rats were investigated.Methods: Twenty-four female Wistar rats (250-300 g) were crossed with males. After pregnancy, the treatment group received 0.1 mg/ml of MORPHINE in drinking water daily (14 ml water/100 g of body weight for each rat), while the control group received tap water. Eight days and 12 hours after the onset of pregnancy, the animals were anesthetized by chloroform and the embryos were taken out surgically. Lengths of embryos were determined by a Caliper. Embryos were fixed in formalin 10% and tissue was processed, sectioned and stained with H&E. The sections were examined for NEURAL PLATE DEVELOPMENT by a light microscope and the MOTIC software. Results: Embryonic length in the treatment group was significantly decreased compared with the control group. NEURAL PLATE was observed in the control group. DEVELOPMENT of NEURAL PLATE and other EMBRYONIC LAYERS (ectoderm, mesoderm and endoderm) were delayed in the treatment group. The ectoderm layer group was poorly developed in embryos exposed to MORPHINE.Conclusion: MORPHINE consumption during pregnancy could cause a delay in the DEVELOPMENT of the NEURAL PLATE as well as the EMBRYONIC LAYERS and especially the ectoderm.
