Study Type		In Vivo
Model		20 kHz exposure to rats and analysis of cancer and pathology (long-term bioassay)
Details		Sprague Dawley rats (n = 40, half male, half female) were exposed to 20 kHz triangular magnetic fields at 6.25 microT for 8 h/day, 12 or 18 months. Urinalysis [pH, glucose, protein, ketone bodies, red blood cells (RBC), nitrogen, bilirubin, urobilinogen, and specific gravity], hematological analysis (RBC, hemoglobin, hematocrit, thrombocyte count, and leucocyte count), blood biochemistry (total protein, blood urea nitrogen, creatinine, glucose, total bilirubin, total cholesterol, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase), and organ weight and histopathological analysis of organs (thymus, stomach, intestine, liver, kidney, testis, ovary, spleen, brain, heart, and lung) was performed. The authors report a slight increase in neutrophil and lymphocyte count of exposed female rats on the 12th and 18th month of exposure, respectively, but no other significant effects.
