Effect of miglitol on BAT temperature. A shows representative infrared thermal image of normal chow diet mice (NC), miglitol-treated normal chow diet mice (NCM), high-fat diet mice (HF) and miglitol-treated high-fat diet mice (HFM). B: Interscapular temperature was measured. Values are means ± SE for 4–5 mice. aP < 0.05, vs mice fed normal chow diet (NC). bP < 0.05, vs mice fed normal chow diet plus miglitol (NCM). cP < 0.05, vs mice fed high-fat diet alone (HF).
