| dc.description.abstract | In this study, we determine the curative effects of okra pods (Abelmoschus esculentus L.) extract against lead acetate toxicity in
mice kidney. n-Hexane, ethyl acetate, and methanol solvent were used for extracting okra pods. 1e role of the extract as an
antioxidant was tested by DPPH and FRAP methods. 1e methanol extract was used for experiments in animals. A total of 30 male
BALB/c mice were randomly divided into six equal groups: normal control, negative control (lead-induced), and treatment groups
(lead-induced for 28 days and administration of methanol extract at doses of 50, 100, 200, and 400 mg/kg BW for the 28 days). 1e
following were analyzed in all groups: activity of the antioxidant enzymes, namely, superoxide dismutase (SOD) and catalase
(CAT); oxidant level, namely, malondialdehyde (MDA) and nitric oxide (NO); and markers of kidney injury, namely, blood urea
nitrogen (BUN) and creatinine (Cre). Kidney histopathology was also evaluated. 1is study showed that the methanol extract
showed the highest antioxidant activity (IC50 is 35.21 µg/mL, and FRAP is 57.58 µM Fe2+/g). 1e CATand SOD activities increased
significantly in okra-treated groups (P < 0.05). 1e okra administration groups experienced a significant decrease in MDA, NO,
BUN, and Cre levels (P < 0.05). 1ickness of the epithelial proximal tubule, diameter of the proximal tubule, and percentage of
necrotic cells in proximal tubule decreased, but the diameter ratio of glomerular Bowman’s capsule in mice treated with okra was
optimally improved and repaired like normal control (P < 0.05). 1e results of this study reveal that methanol extract has a very
strong antioxidant effect and can reduce the influence of toxicity induced by lead acetate in mice kidney | en_US |
