Effects of extremely low frequency electromagnetic fields on kidney functions of albino rats in vivo study

Abstract In the present study fifty male albino rats were equally divided into three groups namely A, B and C, group A used as control group, groups B and C were divided into two subgroups namely B 1 , B 2 and C 1 , C 2 respectively. B 1 & C 1 were exposed to 50Hz, 3KV/m electric field (EF) for the periods of 15, 30 days respectively; B 2 &C 2 were housed at normal environmental conditions for the periods of 15, 30 days respectively. Fresh samples of kidney and blood were collected for experimental investigations. The dielectric constant (έ) and electrical conductivity (σ) were measured to investigate any changes in kidney structure. Kidney function was studied through analysis of urea & creatinine after exposure to EF. The results show high significant changes in the value of έ and σ of kidney for all groups as compared with control. EF can induce significant increase in the levels of kidney profile creatinine & urea, these variations were recovered during two weeks after stopping exposure but they did not return to its original control values. Kidney histological section showed abnormal configuration of renal tubules, congested blood vessel and degenerated renal tubules, necrosis, glomerular shrinkage, and increase in space between glomerulus and Bowman's capsule
