The stereological analysis (3-d) of electromagnetic field effects on kidney tissue in male rats
Abstract:   (14802 Views)

 

  ABSTRACT

  Background and Aim: Stereological methods are used for measuring different parts of the kidney and can serve as useful guides for diagnosis and assessment of improvement of this organ. Several instruments produce electromagnetic waves at home or work place and the effect of these waves on human body have attracted many researchers` attention.

  Materials and Methods: This was a descriptive study. 16 rats of wistar race with an average weight of 135 gr were chosen and were randomly divided into two groups. Each group consisted of 8 rats. Experimental group were exposed to electromagnetic field with an intensity of 0.1m tesla for 6 hours a day for one month and control group had the same situation with the instrument turned off. After one month under deep anesthesia kidneys of the rats were extracted, processed and cut into 5-micron slices which stained with H & E. Finally the total volume of kidney, medulla, cortex and glomeruli were measured on the basis of Cavalier principal. The data introduced into SPSS win soft ware and analyzed by means of t-test.

  Results: According to this study the mean values for volumes of kidney and cortex in both control & experimental groups didn’t show any significant difference (p>0.05). There was a significant difference between mean medullary volumes and also between the mean ratios of glomeruli volume to the total kidney volume.

Conclusion: The results of this study showed that electro magnetic field can produce either detrimental effect on kidney volume or histo-pathological impacts on kidney tissue. However, the effect on kidney is different in the presence of variable intensities of electro- magnetization
