Nigella sativa oil attenuates chronic nephrotoxicity induced by oral sodium nitrite: Effects on tissue fibrosis and apoptosis.

Objectives: Sodium nitrite, a food preservative, has been reported to increase oxidative stress indicators such as lipid peroxidation, which can affect different organs including the kidney. Here, we investigated the toxic effects of oral sodium nitrite on kidney function in rats and evaluated potential protective effects of Nigella sativa oil (NSO).

Methods: Seventy adult male Sprague-Dawley rats received 80 mg/kg sodium nitrite orally in the presence or absence of NSO (2.

Cod liver oil ameliorates sodium nitrite-induced insulin resistance and degradation of rat hepatic glycogen through inhibition of cAMP/PKA pathway.

Aims: Sodium nitrite is used to inhibit the growth of microorganisms and is responsible for the desirable red color of meat; however, it can be toxic in high quantities for humans and other animals. Moreover, glycogen, a branched polysaccharide, efficiently stores and releases glucose monosaccharides to be accessible for metabolic and synthetic requirements of the cell. Therefore, we examined the impact of dietary sodium nitrite and cod liver oil on liver glycogen.

Chemopreventive and hepatoprotective effects of Epigallocatechin-gallate against hepatocellular carcinoma: role of heparan sulfate proteoglycans pathway.

Objective: Epigallocatechin-gallate (EGCG) claims a plethora of health benefits including protection against neoplastic diseases. Meanwhile, heparan-sulfate proteoglycans (HSPGs) have defensive role against tumour cell invasion. Therefore, the chemopreventive and hepatoprotective effects of EGCG were studied in hepatocellular carcinoma (HCC) in vivo and in vitro and compared with strong water soluble antioxidant, sodium ascorbate.

Hepatoprotective effects of cod liver oil against sodium nitrite toxicity in rats.

Context: Exposure to high levels of nitrites for a prolonged time have adverse health effects on several organs especially the liver due to oxidative properties. Meanwhile, cod liver oil has been reported to ameliorate organ dysfunction in animal models that involve oxidative stress.

Objective: Examine the impact of dietary cod liver oil on sodium nitrite-induced liver damage.

Novel chemotherapeutic and renal protective effects for the green tea (EGCG): role of oxidative stress and inflammatory-cytokine signaling.

Background: The green tea catechin, epigallocatechin-gallate (EGCG) is a superb nature's medicine candidate. We evaluated the chemotherapeutic/chemoenhancing effects of EGCG in mice bearing the solid Ehrlich ascites carcinoma (EAC) tumor, and jointly monitored levels of serum C-reactive protein (CRP), lipid peroxidation (as malondialdehyde: MDA) and leukocytosis (LC). Besides, we verified whether; and how then, EGCG would protect against a devastating CP-induced nephrotoxicity in rats.

Prominent chemopreventive and chemoenhancing effects for resveratrol: unraveling molecular targets and the role of C-reactive protein.

Background: Resveratrol (RSVL) claims health benefits that pertain to the consumption of red wine/grapes. We currently evaluated the chemopreventive effects of RSVL, as well as its possible chemoenhancing effects when given with cisplatin (CP), in the Ehrlich ascites carcinoma (EAC) solid tumor model. Further, we monitored concomitant changes in serum levels of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-alpha), leukocytic count (LC) and lipid peroxidation (measured as malondialdehyde, MDA).

Chemopreventive and renal protective effects for docosahexaenoic acid (DHA): implications of CRP and lipid peroxides.

Background: The fish oil-derived omega-3 fatty acids, like docosahexanoic (DHA), claim a plethora of health benefits. We currently evaluated the antitumor effects of DHA, alone or in combination with cisplatin (CP) in the EAC solid tumor mice model, and monitored concomitant changes in serum levels of C-reactive protein (CRP), lipid peroxidation (measured as malondialdehyde; MDA) and leukocytic count (LC). Further, we verified the capacity of DHA to ameliorate the lethal, CP-induced nephrotoxicity in rats and the molecular mechanisms involved therein.
