Abstract
Double distilled water samples were exposed for 48 hr. to 50 Hz-powerline electromagnetic field (EMF) strength of 51.2 μT (36.2 RMS). This EMF exposed water was made available to experimental adult Charles-Foster male rats for drinking ad libitum for 30 days. On the 31st day the rats were anaesthetised with ether and then fixed by perfusion with 10% neutral formalin. The Kidneys were dissected out and further fixed in the same fixative. The corresponding control rats provided with unexposed triple distilled water were similarly treated. On gross examination, no anomaly was observed in the kidney of the exposed group. On histological examination, marked spongiform changes leading to degeneration and compensatory proliferation of the glomerular tufts and degeneration of the lining epithelia of the tubules was observed. This study adds a link in demonstrating that powerline exposure induces stable changes in water structures and effects biomechanisms of tissue fluid.
