The purpose of our study is to assist in understanding the effects of wireless electromagnetic waves on carbonic anhydrase (CA) and acetylcholinesterase (AChE) enzymes activities in the different tissues of the rats. For this purpose, two different groups each of which contains eight rats (n=8) were formed as being control group and wireless electromagnetic wave-administered group. The rats were necropsied after 60min from the injection of chemicals into the rats intraperitoneally. The different tissues of the rats were extracted. CA and AChE enzymes activities were measured for each tissue. All the experimental results were provided in mean +/- S.D. Statistical significance was identified to be P<0.05. It was observed that there were significant changes of enzyme activities in wireless-administered group in salivary gland, stomach, colon, liver, and striated muscle tissues.
