Outline of Final Research Achievements

The purpose of our study is to investigate whether mild thermal stimulation (MTS), which causes rectal temperature elevation of approximately 2ºC, would influence on renal ablation model mice. Two weeks after the preparation of 5/6 nephrectomy in mice of the 129x1/SvJ strain background, they were exposed to once-daily MTS for 4 weeks. Serum creatinine and urine albumin levels were reduced significantly in MTS group. Lipocalin-2(NGAL) mRNA and Urine N-acetyl-beta-D-glucosaminidase (NAG) level was decreased without significance. Renal tubular damages were milder in MTS than in non-MTS. MTS exerted protective effects on tubular injury after renal ablation. These results suggest the possibility of systemic thermal stimulation as a potential non-pharmacological therapy against renal failure.
