Exposure of adult male Periplaneta americana to electromagnetic radiation (EMR) emitted by mobile phones has resulted in sharp changes in the various enzymes systems of fat body and haematological profile. Sharp decline in the protein content of fat body together with increase of total free amino acids was observed. While the activity of glutamate oxaloacetate transaminase showed a significant decrease, that of glutamate pyruvate transaminase showed a sharp increase. The content of glucose and uric acid of fat body showed a sharp increase as well. A proteolytic enzyme, leucine amino peptidase showed significant decrease at the third hour of treatment, but a sharp increase at the sixth hour. Another proteolytic enzyme, cathepsin-D showed significant increase in activity both at third and sixth hour. Content of acetylcholine in the central nervous system showed a sharp increase, and organisms were found to be inert and lethargic after the third hour of EMR treatment. Total haemocyte count showed a sharp decline at the third hour, but a sharp increase at the sixth hour, together with imbalance and fluctuations on differential count. Cytopathological changes evidenced by lack of membrane integrity on plasma membrane and nuclear membrane, particularly on granulocyte were also observed. The present study revealed that continuous exposure to EMR of cell phones can result in widespread effects on the brain, neurons, developing cells and enzyme systems.

Abstract


Exposure of adult male Periplaneta americana to electromagnetic radiation (EMR) emitted by mobile phones has resulted in sharp changes in the various enzymes systems of fat body and haematological profile. Sharp decline in the protein content of fat body together with increase of total free amino acids was observed. While the activity of glutamate oxaloacetate transaminase showed a significant decrease, that of glutamate pyruvate transaminase showed a sharp increase. The content of glucose and uric acid of fat body showed a sharp increase as well. A proteolytic enzyme, leucine amino peptidase showed significant decrease at the third hour of treatment, but a sharp increase at the sixth hour. Another proteolytic enzyme, cathepsin-D showed significant increase in activity both at third and sixth hour. Content of acetylcholine in the central nervous system showed a sharp increase, and organisms were found to be inert and lethargic after the third hour of EMR treatment. Total haemocyte count showed a sharp decline at the third hour, but a sharp increase at the sixth hour, together with imbalance and fluctuations on differential count. Cytopathological changes evidenced by lack of membrane integrity on plasma membrane and nuclear membrane, particularly on granulocyte were also observed. The present study revealed that continuous exposure to EMR of cell phones can result in widespread effects on the brain, neurons, developing cells and enzyme systems.
