Cabbage juice supplementation abrogates Lead acetate-induced haematological and haemorheological imbalances in male Wistar rat.

Lead is a hazardous naturally found heavy metal that has been reported to induce haematological alterations. Whether cabbage, a commonly consumed vegetable rich in antioxidants and anticancer compounds, can mitigate these alterations remains unknown. This study investigated the protective effect of cabbage juice against Lead-induced haematological changes. Twenty (20) male Wistar rats were randomly selected into four groups (n = 5) and given distilled water (1 ml/100 g b.wt), Lead acetate (25 mg/kg b.wt), Cabbage juice (1 ml/100 g b.wt), and Lead acetate with Cabbage juice. All treatments were given orally for 28 days. Lead exposure induces normocytic normochromic anemia with substantial leukocytosis, lymphocytopenia, and hyperfibrinogenemia. Lead-intoxicated animals had significantly higher haemolysis and prolonged clotting times. However, cabbage juice reverses these adverse haematological and haemorheological changes induced by Lead acetate. Conclusively, cabbage juice demonstrated antioxidant, anti-inflammatory, anti-thrombotic, and immunomodulatory properties, as well as the ability to protect the red blood cell membrane from damage caused by Lead-induced osmotic stress.

Cabbage (Brassica oleracea) mitigates lead (II) acetate-induced testicular dysfunction in Wistar rats via up-regulation of Bcl-2 protein expression, pituitary-testicular hormonal axis and down-regulation of oxido-inflammatory reactions.

Oxido-inflammatory stress has been involved in lead-induced testicular dysfunction and plants rich in anti-oxidants has been reported to be beneficial in combating heavy metal poisonings in animal studies. However, cabbage juice protective effect on lead-induced testicular dysfunction was investigated in this study. Twenty male Wistar rats were selected into four (n = 5) groups and given distilled water (1 ml/100 g body weight), lead acetate (25 mg/kg body weight), cabbage juice (1 ml/100 g body weight), and lead acetate with cabbage juice, respectively. All treatments were administered orally for 28 days. Sperm count, motility, viability, testosterone, luteinising hormone and follicle-stimulating hormone, testicular Bcl-2 expression, and enzymatic anti-oxidant capabilities were considerably (p < 0.05) decrease in lead-treated animals. However, cabbage juice significantly (p < 0.05) elevated these parameters. Testicular malondialdehyde, tumour necrosis factor-α, nitric oxide and interleukin-6 was elevated by lead acetate. When comparing cabbage juice-treated animals to lead-treated animals, all of these parameters were considerably (p < 0.05) downregulated in cabbage juice-treated animals. Following lead administration, the testes' histomorphological alterations were not totally recovered despite therapy with cabbage juice. Conclusively, this study suggest that cabbage juice mitigates testicular dysfunction associated with lead exposure via its anti-oxidant, anti-inflammatory, anti-apoptotic and androgenic properties.

Ginkgo biloba Supplement Reverses Lead (II) Acetate-Induced Haematological Imbalances, Hepatic and Renal Dysfunctions in Male Wistar Rat.

Lead is a heavy metal abundant in nature that causes haematological imbalances, and hepatic and renal dysfunction, and this imbalance has been linked to oxidative stress. Several reports have shown that natural products are implicated in ameliorating metal poisonings. Ginkgo biloba is a flavonoid-rich natural herbal supplement with several pharmacological properties. The present study investigated effect of Ginkgo biloba supplement (GBS) on lead-induced toxicity. Animals were given a lead dose of 25 mg/kg for 14 days orally and then given Ginkgo biloba supplements of 50 mg/kg and 100 mg/kg orally for 14 days. Animals given GBS had significantly improved haematological and rheological parameters. GBS showed a protective impact in terms of improved kidney and liver histology, anti-oxidant enzyme activity (CAT, SOD, GSH, and MDA), organ function indices, and a lower rate of erythrocyte osmotic fragility. Conclusively, Ginkgo biloba supplementation attenuated lead toxicity by normalization of haematological imbalances, and hepatic and renal dysfunction as well as maintaining erythrocyte membrane integrity.
