  • Descrição: Objetivo: Objective: Fetal alcohol exposure can disturb neuronal development. However the lacking of adequate methods for quantification does not allow a detailed analysis of the impairment. The present work analysed the effects of chronic alcohol consumption during pregnancy on the development of substance P (SP) and tyrosine hydroxylase (TH) central nervous system neurons using the advantage of quantitative image analysis in combination to imunohistochemistry. Métodos e Resultados: Method and Results: Female Wistar rats were divided into two weight-matched groups. One group was given a high protein liquid diet ad libitum containing 37.5% ethanol-derived calories (6.7% v/v) during 21 days. Another group received the same volume of liquid diet containing isocaloric amount of the maltose-dextrin substituted for ethanol. On gestation day 19, embryos were removed and their brains processed for substance P and tyrosine hydroxylase immunohistochemistry. Every five section was systematically sampled and analysed using a Kontron/Zeiss KS-400 Image Analyser. The SP immunoreactive area of the subplate cortical of the cingulate cortex decreased [616.34±51.75 (pair-fed offspring), 446.80±44.5 (EtOH-exposed offspring), p<0.05, n=7 (unpaired t-Test)] The hippocampus of the embryos of the diet alcohol group showed significant lower SP immunoreactive area [887.99±31.75(pair-fed offspring), 607.28±11.87(EtOH-exposed offspring), p<0.001, n=7 (unpaired t-Test)]. The TH
    immunoreactive area of the striatum decreased [4080.62±283.2 (pair-fed offspring), 2053.77±202.4 (EtOH-exposed offspring), p<0.001, n=7 (unpaired t-Test)] and pars compacta of the substantia nigra also decreased [8348.65±178.06 (pair-fed offspring), 6395.29±297.13 (EtOH-exposed offspring), p<0.001, n=7 (unpaired t-Test)] Conclusões: Conclusion: The data indicated that quantitative image analysis method combined to immunohistochemistry are powerful tools to study the neurotoxicity in the central nervous system. Chronic alcohol consumption during pregnancy impairs the development of specific neurotransmitter systems
