Fipronil (FPN) is a relatively new and broad spectrum insecticide that induces toxic effects to animals and humans through induction of oxidative stress. Ginseng is a medicinal plant that has antioxidant, anti-inflammatory, and anti-apoptotic activities. Thus, the current study was conducted to evaluate the anti-toxic potential of ginseng aqueous extract (GAE) against FPN-induced hepatorenal toxicity in rats. Thirty-two male Wistar albino rats were randomly allocated into four equal groups. Rats of the control group received distilled water. The second group was administrated with GAE at a dose of 200 mg/kg b.w. orally day by day for 6 weeks. The third group was intoxicated with FPN at a dose of 4.85 mg/kg b.w. orally day by day for 6 weeks. The fourth group was administrated with GAE 2 h before FPN intoxication. Intoxication of rats with FPN significantly elevated the activities of serum alanine aminotransferase and aspartate aminotransferase and serum levels of urea and creatinine, as well as increased malondialdehyde level and protein expressions of caspase-3 and cyclooxygenase-2 in hepatic and renal tissues. However, it significantly decreased hepatic and renal GSH content and catalase activity. In addition, it induced histopathological alterations in hepatic and renal tissue architectures. Conversely, concomitant oral administration of GAE ameliorated the FPN-induced biochemical, pathological, and histochemical alterations in both hepatic and renal tissues. This study indicated that ginseng attenuates FPN-induced hepatorenal toxicity, possibly via its antioxidant, anti-apoptotic, and anti-inflammatory properties. Graphical Abstract CAL ABSTRACTPHIRAG

The current study was carried out to evaluate the ameliorative effect of fucoidan against aflatoxicosis-induced hepatorenal toxicity in streptozotocin-induced diabetic rats. Sixty-four Wister albino male rats were randomly assigned into eight groups (8 rats each) that received normal saline, fucoidan (FUC) at 100 mg/kg/day orally for 4 weeks, streptozotocin (STZ) at 50 mg/kg/i.p. single dose, STZ plus FUC, aflatoxin B1 (AFB1) at 50 μg/kg/i.p. after one month of the beginning of the experiment for 2 weeks, AFB1 plus FUC, STZ plus AFB1, or STZ plus AFB1 and FUC. Injection of rats with STZ induced hyperglycemia. Rats with STZ-induced diabetes, with or without AFB1 intoxication, had significantly elevated activities of serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase, and levels of serum urea, creatinine, cholesterol, 8-oxo-2′-deoxyguanosine, interleukin-1β, interleukin-6, and tumor necrosis factor-α. In addition, these rats exhibited increased lipid peroxidation and reduced glutathione concentration and activities of superoxide dismutase, catalase, and glutathione peroxidase enzymes in the hepatic and renal tissues. In contrast, administration of FUC to diabetic rats, with or without AFB1 intoxication, ameliorated the altered serum parameters, reduced oxidative stress, DNA damage, and inflammatory biomarkers, and enhanced the antioxidant defense system in the hepatic and renal tissues. These results indicated that FUC ameliorated diabetes and AFB1-induced hepatorenal injuries through alleviating oxidative stress, DNA damage, and inflammation.

The current study was conducted to evaluate the ameliorative and protective potentials of Moringea oleifera leaves ethanolic extract (MOLE) against thioacetamide (TAA) toxicity. A total of 58 male albino rats were randomly assigned into six experimental groups. G1, rats received distilled water. G2, rats were injected with a single dose of TAA (200 mg/kg BW) i.p. G3, rats were given MOLE (300 mg/kg BW) orally for 26 days. G4, rats were injected TAA as in G2 and treated with MOLE as G3. G5, rats were kept for 26 days without treatment then on day 27 injected with TAA as in G2. G6, rats were given MOLE for 26 days then on day 27 injected with TAA. Phytochemical analysis of MOLE indicated the presence of kaempferol, kaempferol malonylglucoside, kaempferol hexoside, kaempferol -3- O -glucoside, kaempferol-3- O -acetyl-glucoside, cyanidin -3-O-hexoside, ellagic acid, quercetin, quercetin-3- O -glucoside, and apigenin glucoside. Intoxication of rats with TAA significantly elevated activities of serum AST, ALT, and ALP; concentrations of malondialdehyde, nitric oxide, and hepatic tissue protein expression of caspase 3 and COX2 with alteration of the histological structures of hepatic tissues, while it decreased serum levels of total protein, albumin, and hepatic tissue contents of reduced glutathione. Also, TAA intoxication resulted in 62.5% mortality in rats of G5. Treatment of TAA intoxicated rats (G4) with MOLE ameliorated the toxic effects of TAA on hepatic tissue structure and function. It decreased serum activities of AST, ALT, and ALP; enhanced hepatic GSH concentration; reduced pathological alterations and lipid peroxidation; and downregulated caspase 3 and COX2 proteins expression in hepatic tissue. In addition, MOLE protected rats of G6 from TAA-induced hepatic tissues injury and dysfunction, and increased survival rate of rats. In conclusion, MOLE had both ameliorating and protecting potentials against TAA-induced rats liver damage through regulation of antioxidant, anti-apoptotic, and inflammatory biomarkers.

The current study investigated the protective potential of Azolla pinnate ethanolic extract (APE) against lead-induced hepatotoxicity in rats. Sixty male Wistar albino rats were randomly allocated into six groups (n = 10). The control group was orally administrated with saline. The second group received lead acetate (100 mg/kg body weight (BW) orally for 60 days). The third group was fed with APE (10 mg/kg BW orally for 60 days). The fourth group was administrated with lead acetate like the second group and APE like the third group, concomitantly, for 60 days. The fifth group was administrated with APE like the third group for 30 days, then orally administrated with the lead acetate like the second group for another 30 days. The sixth group was administrated with lead acetate like the second group for 30 days, then with APE like the third group for a further 30 days. Phytochemical analysis of APE indicated the presence of peonidin 3-O-glucoside cation, vitexin, rutin, thiamine, choline, tamarixetin, hyperoside, astragalin, and quercetin. The latter has been elucidated using one- and two-dimensional nuclear magnetic resonance (1D and 2D NMR) and liquid chromatography–mass spectrometry (LC–MS-MS). Lead acetate increased the serum levels of alanine and aspartate aminotransferases and that of urea, creatinine, tumor necrosis factor alpha, and interleukin 1β, hepatic tissue malondialdehyde contents, and caspase 3 protein expression, as well as altering the hepatic tissue architecture. However, it decreased the serum levels of interleukin 10 and glutathione (GSH) contents, and the activities of catalase and superoxide dismutase in hepatic tissue. In contrast, the administration of APE ameliorated the lead-induced alterations in liver function and structure, exemplifying the benefits of Azolla’s phytochemical contents. Collectively, A. pinnate extract is a protective and curative agent against lead-induced hepatotoxicity via its antioxidant, anti-inflammatory, and anti-apoptotic impacts.

This study assessed prophylactic potentials of silymarin against lead-induced hepatorenal toxicity in rats with the respect to its antioxidant and anti-apoptotic activities. Forty male albino rats were distributed into four groups. Control group is provided with distilled water. Lead acetate group was given lead acetate (100 mg/kg bwt) orally for 10 weeks. The third and fourth groups administered silymarin at doses of 50 or 100 mg/kg bwt, respectively, 1 h before administration of lead acetate for 10 weeks. Lead acetate altered liver structure and function that represented by significant elevation of the activities of serum aspartate and alanine aminotransferases and serum levels of urea and creatinine. Hepatic and renal tissues’ malondialdehyde concentrations were increased, while reduced glutathione content and superoxide dismutase and catalase activities were reduced in the lead acetate group. Also, lead acetate increased caspase-3 mRNA expression and inhibited alpha-fetoprotein mRNA expression in hepatic tissues, as well as it altered liver and kidney tissues’ architectures. In contrast, silymarin ameliorated in a dose dependent mannar the toxic effects of lead acetate on the liver and kidneys through modulation of lead acetate which altered liver and kidney function and structures via reducing lipid oxidation and pathological changes of hepatic and renal tissue structure, improving antioxidant defense system of liver and kidneys, and decreasing pro-apoptotic gene expression in hepatic tissue. This study indicated that silymarin ameliorated lead acetate-induced hepatorenal toxicity via its antioxidant and cytoprotective potentials. Graphical abstract

This study evaluates the antitumor efficacy of hesperidin (Hesp) versus cisplatin (Cis) in Ehrlich ascites carcinoma (EAC)-bearing mice, as well as its protective effect against Cis-triggered nephrotoxicity. Seventy female mice were allocated into control, Hesp, EAC, Hesp-protected, Hesp-treated, Cis-treated, and Cis+Hesp-treated groups. The inoculation of mice with EAC cells significantly reduced the mean survival time, while significantly increased the body weight, abdominal circumference, ascitic fluid volume, viable tumor cell count, and serum carcinoembryonic antigen, urea and creatinine levels, besides various hematological changes. Additionally, kidney tissue of EAC-bearing mice showed a significant increase in the malondialdehyde level, significant decreases in the reduced glutathione content and catalase activity, marked pathological alterations, and a strong Ki-67 expression with a weak caspase-3 expression in neoplastic cells infiltrating the renal capsule. Conversely, the administration of Hesp and/or Cis to the EAC-bearing mice induced, to various degrees, antitumor responses and alleviated the cytotoxic effects of EAC. In addition to the potent antitumor effect of the concomitant administration of Hesp and Cis, Hesp minimized the renal adverse side effects of Cis. In conclusion, Hesp may open new avenues for safe and effective cancer therapy and could be valuable for enhancing the antitumor potency and minimizing the renal adverse side effects of chemotherapeutic drugs.

This study evaluated the protective potentials of Moringa oleifera leaf alcoholic extract (MOLE) against bisphenol A (BPA)-induced stomach ulceration and inflammation in rats. Control rats received olive oil. Second group administered MOLE (200 mg/kg bwt) by oral gavage. Third group was given BPA (50 mg/ kg bwt) for 4 weeks. Fourth group administrated BPA and MOLE simultaneously. Fifth group was given MOLE for 4 weeks then administered BPA and MOLE for another 4 weeks. Bisphenol A induced gastric ulceration and decreased the volume of gastric juice, prostaglandin E2 (PGE2), reduced glutathione (GSH) and interleukin 10 (IL-10) contents, superoxide dismutase (SOD) activity, and proliferating cell nuclear antigen (PCNA) protein in stomach tissues, while increased the titratable acidity, malondialdehyde (MDA), tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) contents, and caspase-3 and NF‑κB proteins in stomach tissue. However, MOLE ameliorated BPA-induced gastric ulceration and significantly increased the volume of gastric juice, PGE2, GSH and IL-10 contents, SOD activity, and PCNA protein while significantly decreased titratable acidity, MDA, TNF-α and IL-6 contents, and of NF‑κB and caspase-3 proteins in gastric tissue. This study indicated that MOLE protected stomach against BPA-induced gastric injury via its anti-oxidant, anti-apoptotic, and anti-inflammatory activities.

This study evaluated the ameliorative potential of grape seed extract (GSE) against Ehrlich solid tumor (EST)–induced hepatic tissue alterations in mice. The control group was infused with physiological saline. The second group received GSE (50 mg/kg day by day orally) for 2 weeks. The third group was subcutaneously injected with 2.5 million of EST cells. The fourth group was injected with EST cells and treated with GSE extract simultaneously. The fifth group was injected with EST cells and kept for 2 weeks until the appearance of a solid tumor, then treated with GSE for 2 weeks. The phytochemical analysis of GSE revealed the presence of total phenols (17.442 mg GAE/g) and total flavonoid (6.687 mg CE/g) with antioxidant activity of 81.506 mg TE/g DPPH. The Ehrlich solid tumor significantly raised the activities of ALT, AST, and ALP; the level of alpha fetoprotein (AFP) in serum; and the protein expressions of hepatic proliferating cell nuclear antigen (PCNA) and tumor suppressor protein (P53), as well as induced DNA damage and pathological alterations in liver tissue. However, it significantly reduced serum albumin and total protein levels. In contrast, the co- or post-treatment of EST-bearing mice with GSE reduced the activities of ALT, AST, and ALP; the level AFP in serum; and hepatic P53 and PCNA protein expressions. In addition, it reduced EST-induced hepatic DNA damage and pathological alterations, while it increased serum albumin and total protein levels. This study suggested that GSE is a potent hepatoprotective agent and both co- and post-treatment of EST-bearing mice with GSE almost had the same effects. Graphical abstract

The present research was set out to delineate the protective and therapeutic potency of hesperidin (Hesp) versus cisplatin (Cis) against the deleterious consequences of Ehrlich ascites carcinoma (EAC) on the liver and the prospective mitigative effect of Hesp against Cis-mediated hepatotoxic side-effects. A total of 70 female mice were randomly assigned into control, Hesp, EAC, Hesp-protected, Hesp-treated, Cis-treated, and Cis + Hesp-treated groups. Mice inoculated with EAC cells exhibited significant reductions in the serum total protein and albumin levels, along with significant elevations of the serum aminotransferases, lactate dehydrogenase, amylase, and lipase activities, and alpha-fetoprotein level. A significant increment in malondialdehyde level concomitantly with significant declines in reduced glutathione concentration and catalase activity were also observed in the liver of EAC-bearing mice. Additionally, marked hepatic pathological changes as well as a strong Ki-67 expression and a weak caspase-3 expression in the neoplastic cells infiltrating hepatocytes were observed. In contrast, the administration of Hesp and/or Cis to the EAC-bearing mice reversed, to varying degrees, the cytotoxic effects of EAC. Besides, Hesp minimized the harmful hepatic chemotherapeutic side-effects of Cis. Overall, Hesp could be a promising phytochemical against EAC-induced cytotoxicity with its potential to improve the antitumor efficacy of chemotherapeutic drugs and minimize their hepatic adverse side-effects.

Ehrlich ascites carcinoma induces hepatorenal injuries while acridine derivatives have antioxidant, anticancer, and anti-inflammatory. Thus, this study evaluated the protective potential of a newly synthesized the 9-diaminoacridine derivative (9-DAAD), N1-(acridin-9-yl) propane-1, 3-diamine hydrochloride, against Ehrlich ascites carcinoma (EAC) induced hepatorenal injury in female mice. Forty female mice were allocated into 4 groups. Group I was injected with 0.1% DMSO subcutaneously and kept a control. Group II received 9-DAAD (30 mg/kg bw/2 days) subcutaneously for 2 weeks. Group III was injected interaperitonealy with 2.5 × 10 6 cells of EAC/20 g bw. Group IV was injected with EAC as the third group and administered with 9-DAAD as the second group for 2 weeks after induction of EAC. EAC significantly elevated total leukocytes and platelets counts; activities of serum AST, ALT, and ALP; serum levels of alpha-fetoprotein; carcinoembryonic antigen; urea and creatinine; and expression of vascular endothelial growth factor protein in hepatic and renal tissues. Meanwhile it decreased red blood cells count, hemoglobin concentration and hematocrit value. At the same time, it significantly reduced serum levels of total protein and albumin and altered hepatic and renal tissues structures. Also, EAC decreased apoptosis and DNA synthesis in hepatic and renal cells. However, treatment of EAC-bearing mice with 9-DAAD improved liver and kidney structures, functions and modulated EAC altered parameters, as well as it reduced hepatic and renal cells proliferation and DNA synthesis. This study indicated that 9-DAAD had a potential ameliorative effect against EAC-induced hepatorenal injury.
