Abstract:

Purpose: The aim of this study was to investigate the effects of dimenhydrinate on neural tube development in an early chick embryo model. Materials and Methods: 32 fertile, specific pathogen free eggs were used in the study. All eggs were divided into four groups with 8 eggs in each group. At the 28th hour of the incubation, three different doses of dimenhydrinate (0.7, 1.4, 2.1 mg/kg) were injected into the experimental groups and physiological saline was injected into the control group. At 48th hour of incubation, all embryos were dissected and evaluated histologically under the light microscope. Results: When the control, low, medium and high dose group embryos were evaluated morphologically, their mean craniocaudal lengths were 8493.73±1342.90 µm, 5743.61±770.3 µm, 5572.62±315.32 µm, 5306.55±1135.99 µm respectively, mean of somite numbers were 15.91±1.62, 15.38±1.19, 15.13±0.83, 10.63±5.15 respectively. Craniocaudal lengths and somite numbers decreased depending on the increase in the dimenhydrinate dose. The incidence of open neural tube increased due to the increase in dimenhydrinate dose. Conclusion: Neurogenesis and morphological development were negatively affected due to the increase in dose in the groups treated with dimenhydrinate in the early chick embryo model.
