Cold stress may result in development of neuro-psychiatric symptoms such as depression, cognitive impairment, cardiovascular and respiratory diseases, immune suppression, gastrointestinal mucosal damage & potential dysfunction to adrenal glands, kidney & lungs. Present study investigates the changes in metabolic profiles of kidney tissue in rats due to prolonged cold stress using NMR & multivariate statistical analysis. Results shows marked increase in metabolites viz. Lactate, Creatine, Myoinisitol, Glycine & Glucose from day 1 to 5 & decrease on further exposure upto day 15 indicating increased anaerobic glycolysis, altered glomerular filtration rate & osmotic imbalance. Correlation with other parameters can detect early biomarkers for cold stress injuries & organ specific dosimetry.
