“…is fall in the antioxidant enzymes' activities may signify the decrease of the antioxidant activity due to the oxidative stress caused by NaNO 2 . NaNO 2 has inhibitory effects on the SOD and CAT enzymes and other antioxidant enzymes in erythrocytes [30,31]; hence, the levels of O 2 and hydrogen peroxide (H 2 O 2 ) are elevated and cause oxidative stress [7] that can destruct other biomolecules, such as protein, lipid, and DNA [7,11,30,32]. O 2 can irreversibly oxidize non-sulfur centers of the antioxidant enzymes during protein oxidation, leading to their inactivation [33].…”

“…e current study indicated an increase in peroxidation of the PUFA [20] due to oxidative stress. NaNO2 causes hypoxia and the production of free radicals [31] that target the side-chain methylene carbon of PUFA to remove a hydrogen atom from it to start a destructive chain reaction [43]. e decrease of the MDA and F2-isoprostanes in the red okra-treated mice, especially those given 100 mg/ kg BW indicated a decrease in lipid peroxidation.…”

Vegetables, drinking water, and preserved meats may contain sodium nitrite (NaNO2), which causes liver disease by inducing oxidative stress. Phytochemicals are highly recommended as an alternative to synthetic drugs and affordable medicines to treat liver disease because they have fewer or no side effects. Therefore, this study aims to determine the antioxidant and hepatoprotective potential of red okra fruit ethanol extract against NaNO2-induced liver damage. Thirty-six male mice were separated into six groups. The normal control group (WA) was given distilled water only, and the NaNO2 (SN) group was given only 50 mg/kg BW NaNO2. The other four groups (P1, P2, P3, and P4) were given NaNO2 and red okra ethanol extract at doses of 25, 50, 75, and 100 mg/kg BW, respectively. Gavage was administered orally for 21 consecutive days. Commercial kits define all biochemical parameters according to the manufacturer’s instructions. Liver tissue staining followed standard protocols using hematoxylin and eosin. The study revealed that NaNO2 induction causes oxidative stress and damages the liver. The activity of antioxidant enzymes (superoxide dismutase and catalase) significantly increased in the groups treated (P2–P4) with ethanol extract of red okra ( p < 0.05 ). Besides, the oxidants (malondialdehyde, F2-isoprostanes, and nitric oxide) in the liver homogenate significantly decreased in the P4 group, which were given red okra ethanol extract ( p < 0.05 ). Likewise, red okra pods decreased significantly for the serum biochemical parameters of liver damage (aspartate aminotransferase, alkaline phosphatase, and alanine aminotransferase) in the P3 and P4 groups ( p < 0.05 ). Then, it led to a restoration of the histological structure compared to exposed mice (SN), as the pathological scores decreased significantly in the P3 and P4 groups ( p < 0.05 ), as well as the number of the necrotic and swollen liver cells was reduced. Hepatocytes returned to normal. The results showed that the ethanol extract of red okra fruit could be helpful as an affordable medicine. It is an antioxidant and hepatoprotective agent to protect the liver from damage caused by NaNO2.
