Histological preparation was performed as described in Materials and Methods. Values (number of cells per mm2) are expressed as mean ± SEM of 60 fields analysed per animal with a high power objective (40×). Alcian-blue (AB+), safranin (SAF+) and alcin-blue/safranin positive cells (AB+SAF+). * P < 0.05 vs. group I; # < 0.05 vs. I and III-MT; & P < 0.01 vs. II; π P < 0.05 vs. II.
