Abstract
Hibiscus sabdariffa (HS) is native to tropical and subtropical regions, and its enrichment as a source of antioxidants and phytoestrogen has been documented. The present study investigated effects of HS on ovarian toxicity induced by cadmium. Adult female Wistar rats were grouped into 4 (n=5/group): Group A received HS (100 mg/kg), group B received cadmium sulphate (5 mg/kg), group C received cadmium sulphate and HS, and group D (control) received 1 ml of distilled water. Cadmium sulphate was administered for five days (i.p) followed by oral administration of HS for 28 days. Results showed distortion in the cytoarchitecture of the follicular cells in the ovary of cadmium-treated rats while there was mild or no distortion recorded for the ovary of the rats treated with cadmium and HS. There was also a significant reduction in the serum level of Luteinizing and follicle stimulating hormone of the rats treated with cadmium (group B) when compared with control rats. However, these alterations were attenuated when treated with HS. We concluded that HS has an ovarian protective effect in cadmium-treated adult female rats. Hence the present results suggest that HS extract would be a potential therapeutic agent in ovarian dysfunction.

Abstract
Cadmium exposure contributes to internal organ dysfunction and the development of chronic diseases. The aim of the study was to assess the alleviating effect of α-lipoic acid and/or magnesium on cadmium-induced oxidative stress and disorders in bone metabolism, kidney and liver function, and hematological and biochemical parameters changes. Male rats were exposed to cadmium (30 mg Cd/kg of feed) for three months. Some animals exposed to Cd were supplemented with magnesium (150 mg Mg/kg of feed) and/or with α-lipoic acid (100 mg/kg body weight, four times a week). Cd intake inhibited body weight gain and lowered hemoglobin concentration, whereas it increased the activities of liver enzymes, as well as the level of oxidative stress, CTX-1 (C-terminal telopeptide of type I collagen, bone resorption marker), and CRP (C-reactive protein, marker of inflammation); it decreased vitamin D3, GSH (reduced glutathione), and the serum urea nitrogen/creatinine index. Mg and/or α-lipoic acid supplementation increased the antioxidant potential, and partially normalized the studied biochemical parameters. The obtained results show that both magnesium and α-lipoic acid decrease oxidative stress and the level of inflammatory marker, as well as normalize bone metabolism and liver and kidney function. Combined intake of α-lipoic acid and magnesium results in reinforcement of the protective effect; especially, it increases antioxidant defense.

Effect of fatty acids from ethanol extract of Moringa oleifera seeds on kidney function impairment and oxidative stress induced by gentamicin in rats. Biomed Pharmacother 2019; 117:109154. [PMID: 31387184 DOI: 10.1016/j.biopha.2019.109154] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2019] [Revised: 06/15/2019] [Accepted: 06/19/2019] [Indexed: 02/01/2023] Open
Abstract
Gentamicin, an aminoglycoside drug, used for the treatment of Gram-negative bacterial infections. Despite its potency against bacterial infections, its clinical use is limited owing to nephrotoxicity effect. However, the study investigated the nephroprotective effect of fatty acids from ethanolic extract of Moringa oleifera seeds (EEMOS) against gentamicin-induced kidney injury in rats. Forty-five male Wistar rats, 100-160 g, were divided into 5 groups as follows: Group 1 (control), 5 rats, received 0.2 ml/100 g/day of propylene glycol orally for 28 days. Group 2, 10 rats, received 100 mg/kg/day (i.p) of gentamicin (GENT) for 8 days. Group 3-5, 10 rats each, treated with EEMOS orally for 28 days at graded doses of 100, 200 and 400 mg/kg respectively after GENT treatment. Twenty four after treatment, five rats from each group were sacrificed. The remaining 5 rats were sacrificed after 2 weeks recovery period from the drugs. The result showed that GENT elicited polyuria, elevated plasma creatinine, urea, and lower plasma electrolytes and creatinine clearance levels. Measurements of 24 h urinary output demonstrated marked decrease in creatinine and potassium levels in the GENT-treated group, whereas sodium level remain unchanged. Also, GENT caused significant decrease in superoxide dismutase and an increase in malondialdehyde levels in the kidney of the rats. Histopathological examination revealed evidence of necrosis of the kidney. Treatment with EEMOS significantly ameliorated the alterations caused by GENT in the plasma, urine and kidney homogenate of the rats. Hence, the mono- and poly-unsaturated fatty acids present in EEMOS were responsible for its renoprotective ability.

Abstract
Exposure to cadmium (Cd), even at low doses, is of serious health concern because it does not undergo metabolic degradation to less toxic metabolite. Liver injury/disease, with a world-wide increasing incidence, is one of the consequences of exposure to Cd toxicity. This study aimed at determining the effects of acetonic extract of Vernonia amygdalina leaf (AEVAL) in a Wistar rat model of Cd-induced liver injury. Phytochemical screening of the extract was carried out and its oral LD50 was determined to guide the choice of therapeutic doses. Thereafter, thirty male Wistar rats were recruited for this study. The experimental groups received 4 weeks oral graded doses of the extract (100, 200 and 400 mg/kg) following Cd-induced liver injury. Cd-induced liver injury (5 mg/kg i.p for 5 consecutive days) was characterized by deleterious alterations in the levels of AST, ALT, ALP, total bilirubin and hepatic total protein (p ˂ 0.05). Also, deleterious alteration of oxidative stress indicators (GSH, SOD and CAT) and lipid peroxidation index (TBARS) was observed in the liver homogenates. Histopathological examination showed evidence of degenerated hepatocytes as well as inflammation with disseminated steatosis. These conditions were significantly attenuated (p ˂ 0.05) following treatment with graded doses of the extract, with the highest dose expressing least therapeutic effects. This study concluded that AEVAL attenuated Cd-induced liver injury and is, potentially, a suitable option in adjuvant therapy for heavy metal toxicity.

Abstract
Proximal tubule protein take-up is interceded by 2 receptors, megalin and cubilin. These receptors rescue an assortment of filtered ligands including fundamental vitamins and hormones. The objective of this study was to investigate the potential relation of megalin receptor injury with nuclear factor-kappa B (NF-κB) upregulation in acute kidney injury rat model. Twenty four rats were allocated into two groups: control group received saline, while the second group was intoxicated with cadmium chloride (2.4 mg Cd/kg/day i.p) for 30 days. Blood urea nitrogen, serum creatinine, tissue oxidant-antioxidant parameters (malondialdehyde [MDA] and reduced glutathione [GSH]) and expression levels for NF-κB, toll like receptor-2 (TLR2), toll like receptor-4 (TLR4), and megalin receptor were estimated. Noticeable downregulation of megalin receptor versus upregulation of NF-κB, TLR2, and TLR4 were observed in AKI rat model together with significant elevation in MDA as well as significant reduction in GSH. The study concluded that the oxidative stress in kidney tissue leads to megalin receptor damage, which indeed motivates upregulation of NF-κB through TLRs 2 and 4 pathways.

Abstract
The effects of aqueous extract of Ocimum gratissimum leaf (AOGL) on the renal function of rats with gentamicin-induced nephrotoxicity were investigated. This study involved the use of forty five (45) adult male Wistar rats (housed in separate metabolic cages) such that graded doses of OAGL were administered to the experimental groups (p.o.) for 28 days after exposure to gentamicin toxicity (100 mg/kg i.p.) for 1 week. At the end of the study, comparisons of some indices of renal function as well as antioxidant status (GSH and TBARS) were made between the control, toxic and AOGL-treated groups at P < 0.05. The result showed that gentamicin treatment caused significant increase (P < .05) in urine output, urea, creatinine, total protein, relative kidney weight, and TBARS, as well as significant decrease (P < .05) in urine creatinine and GSH levels. Post-treatment with graded doses of AOGL caused significant increase in food consumption, GSH, urine, and plasma creatinine, as well as significant decrease (P < .05) in relative kidney weight, TBARS, and urine total protein. There was an appreciable difference in the kidney histology of the AOGL-treated groups when compared with the toxic control. Hence, the extract has therapeutic potential in the management of gentamicin-induced kidney injury, although a risk profile of renal dysfunction is not unlikely from 28 days of administration as evident by the decrease in creatinine clearance.
