In the current study, we used STZ-treated diabetic rats with DN to assess the effects of whole-body exposure to 15 Hz ELFPMF whose peak magnetic flux density (MFD) was approximate 1.6 × 10−3 T on the development of renal changes in DN by using morphological examination and ELISA analysis for VEGF-A and CTGF. Here, VEGFA is linked to liver dysplastic nodule.
