Assessment of pioglitazone effects on peripheral tissues. A) Heart (left axis, white bars) and adrenal weights (right axis, black bars) were normalized to body weight (mg/gr) in animals fed either control diet (CTRL) or PIO-enriched diet (PIO). B) Left, representative examples of liver sections stained with oil red O and hematoxylin from a CTRL and PIO-treated animal. Right, data showing percent of sections stained for lipids (% area stained) in both groups. Data represent Mean ± SEM, *p < 0.05, T-test.
