Extracts of both Curcuma longa (CL) and Nigella sativa extract (NS) are reported to have protective effects on renal damage. In this study, we investigated the protective effect of a combination of NS and CL on Adriamycin (ADR)-induced renal damage. Forty eight rats were divided into six groups as: Control (CO), ADR, Vitamin C + ADR, CL + ADR, NS +ADR, and CL + NS + ADR. ADR was injected intravenously on the 7th day of the study. 24-hour urine and orbital blood samples were collected on day 0, 48 hr after ADR injection and at the end of weeks 2, 3, 4, and on the 35th day. Glomerular filtration rate (GFR) was calculated on each sample, and on the 35th day, renal index and histological changes were also evaluated. In the ADR-treated rats, significant renal pathological changes were demonstrated compared to CO group. The renal index and urine protein excretion significantly increased, and serum albumin and GFR in the ADR-treated rats were significantly decreased compared to CO group. In NS + ADR group, the serum albumin significantly decreased compared to ADR group. In CL + NS + ADR group, the urine protein excretion was lower than ADR group, and serum albumin concentration was significantly higher than ADR group. In addition, in CL + ADR and NS + ADR groups also, the urine protein was significantly lower compared to ADR group. This study shows that the mixed extracts of N. sativa and CL have positive synergistic effects on renal damage in nephropathy induced by ADR in rats.
