Última Maternal Chronic Stress Induces Premature Telencephalic Vesicles Development International Journal of Morphology Mugnaini,María Teresa; Soñez,Carlos Alberto; Rolando,Alicia Nélida; Romanini,María Cristina; Bozzo,Aída Andrea; Pastorino,Isabel Cecilia; Gauna,Héctor Fernando; Paz,Dante Agustín. Exposure to physical or psychological stress causes brain damage ranging from minimal behavioural alterations to different neurodegeneration degrees implying the overproduction of oxidative-nitrosative compounds, apoptosis and cell proliferation. In the present investigation, we have analysed the effect of the chronic stress by immobilisation applied to pregnant rats over the forebrain development of the embryos. The morphometric analyses showed an accelerated evagination of the telencephalic vesicles in 12 days old fetus from stressed mothers. The forebrain perimeter and the thickness showed significative differences in relation to age-matched controls. This stress effect seemed reversible during subsequent gestational stages. This is the first work... Tipo: Journal article Palavras-chave: Telencephalic vesicle; Chronic stress; Morphometric analysis; Rats.

Chronic stress by immobilization during gestation can alter several mechanisms that maintain homeostasis in adrenal gland. The aim of this work was to quantify the apoptotic index of adrenal cortex during mid-pregnancy and to prove cytological characteristics by electron microscopy. The apoptotic index did not present significant differences between the adrenal cortex areas of control and experimental rats in any of the three ages studied. The day of gestation influenced significantly on the apoptotic index in both groups. This index increased as gestation progressed. It may be concluded that chronic stress by immobilization might induce the increase of apoptotic index in adrenal cortex as gestation progresses which might be related variations of plasmatic...
