attenuates chromium-induced nephrotoxicity via antioxidant and anti-inflammatory activities in mice.

Chromium (Cr) is a common environmental pollutant that has wide-ranging toxic manifestations. () is an herbal medicine with anti-inflammatory properties and antioxidant activity. This study aims to evaluate the protective role of (whole plant) in attenuating Cr-induced nephrotoxicity in Swiss mice. Swiss albino mice were divided into five groups (10 mice in each): group I (control); group II (-treated); group III (Cr-intoxicated); group IV (Cr- and saline-intoxicated); and group V (Cr-intoxicated and -treated). Blood samples were drawn after sacrifice for biochemical examinations. Kidney specimens were collected to examine antioxidant activities and conduct histological and immunohistochemical studies for all groups. Mice intoxicated with Cr at 15 mg/kg/b.wt showed a decrease in superoxide dismutase (SOD), glutathione S-transferase (GST), and glutathione peroxidase (GSH-Px) levels compared to the control group, followed by an elevation in the serum IL-6 level. The data revealed severe damage to the renal tubular epithelial cells as well as marked congestion and positive, diffuse, and strong expression of caspase-3 in the dilated tubules. Additionally, the data disclosed an increase in the serum level of blood urea nitrogen (BUN) and creatinine in group III compared with group I. Group V, treated with at a selected dose of 120 mg/kg/b.wt, showed an improvement in antioxidant activity, attenuation of the IL-6 level, fewer histopathological disturbances, and a statistically significant decrease in the serum level of BUN and creatinine compared with group III. Such changes may be attributed to the antioxidant and anti-inflammatory effects of . Therefore, our investigation revealed that effectively protects against Cr-induced nephrotoxicity.
