In this study, we aimed to investigate the protective effects of melatonin (MEL) and S-methylisothiourea (SMT) on mechlorethamine (MEC) induced nephrotoxicity. A total of 36 male Sprague-Dawley rats were divided into four groups: control, MEC, MEC+MEL, and MEC+SMT. Three groups received single dose of MEC (3.5 mg/kg) via transdermal route. Control animals were given saline only via transdermal route. MEL (100 mg/kg) was administered intraperitoneally 30 min after the application of MEC, and after the same dose of MEL was given every 12 h for a total of six doses. SMT (50 mg/kg) was also given intraperitoneally 30 min after the application of MEC. The tissue TNF-α, IL-1β, and NOx levels were found significantly different for all groups (P < 0.001). MEC application resulted in severe histopathological changes. Melatonin showed meaningful protection against kidney damage. But protection by SMT was weaker. TNF-α and IL-1β levels increased significantly with MEC application, and MEL and SMT ameliorated these increases in kidney tissue. MEC also elevated NOx levels in kidney tissue. Both inflammation and oxidative stress may have an important role in the MEC induced nephrotoxicity. MEL and SMT may also have anti-inflammatory properties, as well as anti-oxidant properties.
