The ultramicrotome was then used to prepare thin sections, which were collected on a copper grid and stained with lead citrate and uranyl acetate Comparisons between variables were tested by Student t test of means, the paired Student t test or Mann-Whitney U test, as appropriate.

After dehydratation in a growing gradient of ethanol, 5 min for each step: 30, 50, 70 and 95\%, impregnation steps and inclusion were performed in Epon finally polymerized at 60°C for 48 h. 60-80 nm sections were obtained using an ultramicrotome RMC-MTX (Tucson), and contrasted with uranyl acetate and lead citrate.
