Figure 3. Examples of renal histology obtained from mice in the ‘juvenile’ vs. the ‘mature’ mouse groups that were subjected to the maleate (A, B) or glycerol (C, D) model.

Maleate treated ‘juvenile’ mice maintained essentially normal histology (A). Conversely fulminant tubular necrosis with cast formation was observed in the ‘mature’ group subjected to maleate injection (B). Glycerol had a minimal effect on renal histology in ‘juvenile’ mice (C). However, glycerol induced marked tubular necrosis and cast formation when administered to ‘mature’ mice (D).
