The specimen then cleared in three changes of propylene oxide 15

minute each. The specimens then impregnated in two successive mixtures of'

propylene oxide and epon {(1:1) for one hour, then, (2:3) for six hours} and

finally in epon alone for 12 hours at room temperature.

Tissue specimens were embedded with epon in a flat silicone rubber

molds and then polymerized at 60 ºc for 48 hours after appropriate orientation

using fine wooden stick.

2.8. Sectioning:

Rectangular flat blocks containing the specimens, were removed from

the moulds and trimmed by clean razor.

Both semi-thin (1-µm) and ultra-thin (~80nm) sections from the kidney

were cut using ultra microtome (Reichert-Jung, Licea Germany) using glass

knifes for semi-thin sectioning and diamond knife (Reichert-Jung, Licea

Germany) for ultra-thin sectioning.

The glass knifes were prepared by cutting triangular pieces with sharp

apical edge from 5 square inch glass plates of 6 mm thickness using glass

cutting device (Reichert-Jung, Licea Germany).

2.9. Staining:

The semi-thin sections were mounted on glass slide and stained with

Toluidine blue. Thin sections were mounted on cupper microgrids of 200

meshes (Reichert-Jung, Licea Germany) and stained with 0.2% lead citrate and

aqueous solution of uranyl acetate.
