Abstract: Objective T o observe the chem ical groups changing in rat kidney w ith regard to fatal hyper-therm ia by Fourier transform infrared m icrospectroscopy (FT IR-M SP ) and to provide a new m ethod to diagnose fatal hypertherm ia. Methods R ats w ere sacrificed by hypertherm ia, brainstem injury, m assive hem orrhage and asphyxiation and divided into groups. T he renal sam ples w ere dissected im m ediately af-ter death. T he data of infrared spectroscopy in glom erulus w ere m easured by FT IR-M SP. Results T he absorbances of 3 290, 3 070, 2 850, 1 540 and 1 396 cm -1 significantly increased (P<0.05),and the ratios of A1650/A3290 and A1650/A1540 significantly decreased (P<0.05) in group of hypertherm ia. Conclusion FTIR-M SP can analyze the changes of chem ical groups of kidney as an auxiliary diagnosis for discrim inating hyper-therm ia w ith other causes of death.
