Scanning electromicrograph in renal tissue showing a control group with normal ultrastructure (× 1500), b CS-treated group without deviation from control group (× 1300), c Li-treated group with obvious lesions represented by deep irregular cracking with cellular bridging (× 1300), d CS pre-treated group without alterations or deviation from control group (× 1000), e CS simultaneous-treated group with severe ultrastructural alterations represented by deep irregular cracking with cellular bridging (× 1700), and f CS post-treated group with ultrastructural variations represented by irregular cracking with cellular bridging in addition to cellular lose (× 1000)
