Immunohistopathologic demonstration of deleterious effects on growing rat testes of radiofrequency waves emitted from conventional Wi-Fi devices.

[Immunhistopathologische Demonstration nachteiliger Wirkungen hochfrequenter Wellen, emittiert durch konventionelle Wi-Fi-Geräte, auf das Wachstum von Ratten-Hoden].

Veröffentlicht in: J Pediatr Urol 2013; 9 (2): 223-229

Ziel der Studie (lt. Autor)

Es sollten die Wirkungen einer Hochfrequenz-Befeldung, emittiert durch WiFi-Geräte, auf die Hoden von Ratten untersucht werden.
Hintergrund/weitere Details: 10 Ratten wurden in eine Expositions-Gruppe und eine Kontrollgruppe aufgeteilt (jede Gruppe n=5).

  • nicht spezifiziert
  • ADSL 2 + gateway
Kammer rats were housed in acrylic-glass cages (20 x 30 x 40 cm)
Aufbau three cages were placed in a row with 1 - 2 animals each; two commercial ADSL 2 devices + gateways were located at a distance of 25 cm at both longitudinal sides of the middle cage; gateways were wirelessly bridged to each other
Scheinexposition Eine Scheinexposition wurde durchgeführt.
Zusatzinfo ADSL 2 contains of hard disk and network storage link; data transmission was performed after each hard disk was assigned as a network drive

Hauptergebnis der Studie (lt. Autor)

Die Autoren fanden signifikante Erhöhungen der 8-Hydroxy-2-Desoxyguanosin-Werte im Serum und in den Hoden der exponierten Gruppe. Zusätzlich waren die Katalase- und Glutathionperoxidase-Enzymaktivitäten bei den exponierten Tieren vermindert.
Die Autoren kommen zu dem Schluss, dass eine anhaltende WiFi-Exposition oxidativ die Hoden wachsender Ratten beeinflusst.
