Pregestational Obesity-Induced Embryopathy.
2016
Introduction:Several epidemiologic studies in humans have shown a relationship between pregestational obesity and congenital malformations in offsprings. However, there are no experimental evidence in animal models of obesity and pregnancy that reproduce the teratogenesis induced by this pathological condition.Objective:To evaluate the effect of monosodium glutamate-induced obesity on embryonic development.Methods:Female rats received subcutaneously (4 mg/g body weight) monosodium glutamate (MSG) solution or saline solution 0.9% (vehicle control) at days 2, 4, 6, 8, and 10 of life. At 90 days of age, all animals were mated, and on day 11 of pregnancy, the animals were killed. Biochemical variables (glucose, triglycerides, total cholesterol, and insulin) were determined in plasma of dams and embryo homogenates (DNA and protein content, advanced oxidation protein products). Embryos were evaluated for malformations, crown-rump length, and somite number.Results:Obese rats presented higher triglyceride levels ...
