Figure 3. Oxidation rate of lipoprotein triacylglycerol-fatty acid in isolated working hearts from lean and obese ZDF rats perfused with triacylglycerol (TAG)-rich lipoproteins.

Isolated rat hearts were perfused with very-low-density lipoprotein (VLDL) or chylomicrons (CM) (0.4 mm TAG) prepared from lean control or obese diabetic rats together with [¹⁴C]glucose (11 mm); for further details see text. Results are expressed as means ±s.e.m. (n= 7 per group). Statistically significant differences between diabetic and control hearts are indicated: **P < 0.01; significant differences between diabetic and control lipoproteins are indicated: ^#P < 0.05; significant differences between VLDL and CM are indicated: ⁺P < 0.05; significant differences between diabetic hearts perfused with diabetic lipoproteins and control hearts perfused with control lipoproteins are indicated: ‡P < 0.05.
