Due to kidney damage cadmium, this study was an attempt to investigate the protective effect of aqueous extracts of marjoram cadmium in kidney. 30 male Wistar rats divided into 5 equal groups randomly: control and treatment groups 1 to 4 (T1-T4), respectively. T1 group was administrated at 2 mg/kg cadmium chloride intraperitoneal and T2, T3 and T4 groups in addition to cadmium aqueous extract of marjoram at a dose of 125, 250, 500 mg/kg, respectively. On the last day, the animals were weighed and blood samples for serum preparation were isolated. So that the animals were euthanized with overdose of thiopental. The right kidney was used to measure malondialdehyde and the left one was fixed in formalin-buffer 10% to pathologic studies. The results showed that the T1 group had the lowest average body weight. The different weight between the T1 group and control, 250 and 500 mg/kg of extract was significant. The MDA difference between T1 Group, T4, and control group was significant (P=0.041). The TCA concentration in T4 group was the highest of 1198.91 ± 51.45 and in T1 was the lowest average 796.41 ± 40.76 µmol/ml and the difference was significant (P=0.036). The pathological damage was graded with the degeneration of tubules of kidney, necrosis and accumulation of inflammatory cells. The high to low scoring damage was found in Group T1, T2, T3, C and T4 respectively. According to the findings, 500 mg/kg of O. vulgaris extract can prevent kidney damage caused by cadmium chloride in rats.
