In situ detection of gliosis and apoptosis in the brains of young rats exposed in utero to a Wi-Fi signal

Pregnant rats were daily whole-body exposed or sham-exposed to a Wi-Fi signal in a free-running reverberation chamber at 0, 0.08, 0.4, and 4 W/kg for 2 h during the last 2 weeks of gestation (5 days/week). Following this in utero exposure, the pups were divided into two groups and 1 group continued...

Summary:Pregnant rats were daily whole-body exposed or sham-exposed to a Wi-Fi signal in a free-running reverberation chamber at 0, 0.08, 0.4, and 4 W/kg for 2 h during the last 2 weeks of gestation (5 days/week). Following this in utero exposure, the pups were divided into two groups and 1 group continued exposure for 5 weeks after birth. Several brain areas were examined for gliosis and apoptotic cells. Comparison among sham and exposed groups revealed no significant differences, suggesting that in utero and post-natal exposure to Wi-Fi did not damage the brains of the young rats. Des rates gestantes ont été exposées corps-entier à un signal Wi-Fi, sans contrainte de mobilité, dans une chambre réverbérante à des niveaux d'exposition de 0 ; 0,08 ; 0,4 et 4 W/kg et ce, durant les deux dernières semaines de gestation. Suite à cette exposition in utero quotidienne (2 h, 5 jours/semaine), chaque portée obtenue a été divisée en deux groupes dont un, poursuivant l'exposition jusqu'à 5 semaines après la naissance. La détection de gliose et de cellules apoptotiques a été réalisée au niveau de différentes régions du cerveau des jeunes rats. Aucune altération n'a été observée suite à l'exposition Wi-Fi in utero et post-natale.
