Materials and Methods: The mice received a single IP injection of Cis (20 mg/kg) on the first day of the experiment. Suma treatment (0.1 and 0.3 mg/kg/day, IP) was started on day 1 and continued for 3 consecutive days.

Results: Creatinine (Cr), blood urea nitrogen (BUN) and malondialdehyde (MDA) levels were elevated and glutathione peroxidase (GPx) as well as superoxide dismutase (SOD) activities were decreased in Cis-treated mice. Suma (more potently 0.3 mg/kg) reduced Cr, BUN and MDA levels and increased SOD and GPx levels. Suma also reduced the acute renal injury (tubular degeneration, tubular cells vacuolation, tubular necrosis and cast), which corresponded to kidney damage in Cis-treated mice.

Conclusion: These findings demonstrate that Suma mitigates Cis-induced renal injury by inhibition of oxidative stress and enhancing the antioxidant enzymes activities.
