RESUMO
<p><b>OBJECTIVE</b>To study the metabolic changes of pancreatic extracts from insulin-resistant rats induced by fructose feeding using nuclear magnetic resonance ¹H spectroscopy (¹H NMR).</p><p><b>METHODS</b>Sixteen Wistar rats were divided equally into control group and model group and given water and 10% fructose water for 8 weeks, respectively. The pancreatic tissues were then obtained for H NMR spectra analysis and principal component analysis (PCA).</p><p><b>RESULTS</b>Compared with the control rats, the rats in the model group showed significantly increased creatine, betaine/TMAO, taurine, glycine and myo-inositol and decreased levels of lipids, lactate, glutamate, choline and GPC/PC.</p><p><b>CONCLUSION</b>¹H NMR and pattern recognition can define the metabolic characteristics of the pancreatic tissue extracts from insulin-resistant rats and provide reliable metabolic evidence for studying the mechanisms of insulin resistance at the molecular level.</p>
