The present study investigated the protective effects of N-acetylcysteine (NAC), is widely known as an antidote to acetaminophen overdose, on carbosulfan (CB)-induced hematotoxicity and oxidative stress in male rats. CB was administered at a dose of 25 mg/kg or simultaneously administered with NAC (2 g/l) for 30 days. Results of hematological examination showed that red blood cells, hematocrite, hemoglobin, and reticulocytes levels were significantly lower in CB-exposed rats compared with those in the control. Administration of CB caused a significant increase in the superoxide dismutase and catalase activities. However, the glutathione (GSH) and thiols group (TSH) levels were significantly increased as well as GSH S-transferase activity and levels of glutathione peroxidase on erythrocytes of males rats compared with those in the control. Also, CB-treated rats showed significant elevation in lipid peroxidation (LPO) and acetylcholinesterase (AChE) on erythrocytes in comparison with the control. Co-administration with NAC exhibited chemoprotective effects against CB-mediated hematotoxicity, augmented erythrocyte antioxidant status, and prevented the induction of anemia.

Abstract Cadmium (Cd) is an environmental toxic metal implicated in lipid abnormalities. The present study was designed to elucidate the possible association between chronic exposure to Cd concentration and alterations in plasma lipid, lipoprotein, and oxidative stress indices in rats. Sixteen male rats were assigned to 2 groups of 8 rats each (test and control). The Cd-exposed group obtained drinking water containing cadmium chloride (CdCl2) in the concentration of 2.0 mg Cd/L in drinking water for 3 months. At the end of the experimental period, blood samples were obtained to determine the changes of serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), reduced glutathione (GSH), malondialdehyde (MDA) and also serum Cd contents. The results of the present study indicated that Cd administration significantly increased the serum levels of TG, TC, LDL-C, MDA and Cd with reduction in the HDL-C and GSH levels. In conclusion, evidence is presented that chronic exposure to low Cd concentration can adversely affect the lipid and lipoprotein profile via lipid peroxidation.

In this study we evaluated the possible protective effects of selenium (Se) on hematological and oxidative stress parameters in rats chronically treated with cisplatin (cisPt). Four groups of Wistar albino rats were examined: a control, untreated rats (I), rats treated with Se (II), rats treated with cisPt (III), and rats treated with Se and cisPt (IV). All animals were treated for 5 days successively and killed 24 h after the last treatment. Hematological and oxidative stress parameters were followed in whole blood and red blood cells (RBC). Results showed that the chronic application of Se was followed by a higher number of reticulocytes and platelets, increased lipid peroxidation and GSH content in the RBC. Cisplatin treatment induced depletion of RBC and platelet numbers and an elevation of the superoxide anion, nitrites and glutathione levels. Se and cisPt co-treatment was followed by an elevation of the hematological parameters and the recovery of the glutathione status when compared to the control and cisPt-treated rats.

Several strategies for discovering drugs from unexplored natural products continue to strengthen research and development with current commercial evidence supporting their applications. We assessed the effects of the hydroethanolic extract of Acridocarpus smeathmannii root (HEASR) against phenylhydrazine (PHZ)-induced haematotoxicity, biochemical changes, and oxidative stress in male Wistar rats. Groups 1 and 2 controls received normal saline (10 mL/kg/day) and PHZ (60 mg/kg, day 4 and 5), respectively, via oral gavage. Groups 3, 4, and 5 were administered dexamethasone (DXM, 0.014 mg/kg/day, p.o.), HEASR1 (50 mg/kg/day, p.o.) and HEASR2 (200 mg/kg/day, p.o.), respectively. Groups 6, 7, and 8 received HEASR2 (200 mg/kg/day), DXM (0.014 mg/kg/day), or their combination, respectively, and further received PHZ (60 mg/kg/day) intervention on day 4 and 5 only. Treatments lasted for 7 days. Phenylhydrazine toxicity manifested as lowered haemoglobin, white blood cells, lymphocytes, red blood cells, and platelet levels by 45.86%, 53.47%, 75.69%, 46.89%, and 30.29%, respectively, in rats. This was accompanied by an increase in serum alanine (ALT; 108.25%) and aspartate (AST; 78.79%) aminotransferases, urea (84.36%), total cholesterol (81.55%), and triglycerides (123.42%) levels. Similarly, malondialdehyde levels and serum cyclooxygenase-2 activity were elevated ( P < 0.05) in the rats liver and spleen, respectively. Just HEASR alone, or in combination with DXM, preserved haematological and biochemical parameters, cyclooxygenase-2 activity, and corticosterone levels during PHZ intoxication and restored renal histopathological alterations in rats. The HEASR was found to contain high flavonoid and phenolic phytochemicals and demonstrated better in vitro antioxidants inhibitory action.

This study was conducted to assess the antioxidant status and hypolipidemic role of purified diosgenin extracted from fenugreek seeds in hydrogen peroxide (H2O2) and atherogenic diet experimentally induced oxidative stress male rats. Hexane and chloroform were used for the extraction of diosgenin from ground fenugreek seeds. Purification of extracted fraction was carried out on Sephadex LH-20 column using ethyl acetate as eluent, homogenous symmetrical peak was obtained, and thin layer chromatography on silica gel confirmed that purified fraction is diosgenin in compression to standard diosgenin and the calculated Rf values. The antioxidant scavenging activity was carried out using 2, 2, 1 diphenyl- 1- picrylhydrazyl (DPPH) assay, the result showed that purified diosgenin has an antioxidant activity 13.68 μg/ml while the corresponding values for vitamin C and butylated hydroxyl toluene were 8.43 and 7.26 μg/ml respectively. Fifteen adult Albino male rats were randomly and equally divided into three groups, and treated for six weeks as follows; G1 group served as control, G2: Animals of this group were received drinking water containing 0.75% H2O2 and atherogenic diet, Group 3; Rats of this group were given drinking water containing 0.75% H2O2 and atherogenic diet plus 40 mg purified diosgenin/ kg B.W. dissolved in 0.5 ethyl acetate daily by gavages needle. Fasting blood samples were collected by cardiac puncture technique at 0, third and sixth weeks of experiment. The results revealed that rats in G2 exposed to oxidative stress (0.75% H2O2 plus atherogenic diet) showed a significant elevation (P<0.05) in serum total cholesterol (TC), triacylglycerol (TAG), low density lipoprotein- cholesterol (LDL-C) as well as in malondialdehyde (MDA), and significant suppression in serum high density lipoprotein- cholesterol (HDL-C) and glutathione (GSH) concentrations in comparison to the animals in the first group (G1 group). Intubation of 40 mg/kg B.W. of purified diosgenin was caused a significant alteration in the lipid profile of the treated group (G3), manifested by significant reduction (P<0.05) in serum TC, TAG, LDL-C and significant elevation in HDL-C. Antioxidant status also exhibits significant changes manifested by an elevation of serum GSH and reduction in MDA concentration in G3 group animals. This study has shown the significant role of diosgenin as hypolipidemic agent and its role in restores of the oxidative stress.

Abstract. Background: The pathophysiological basis of chronic kidney disease and its complications, including cardiovascular disease, are associated with chronic inflammation and oxidative stress. We investigated the effects of active vitamin D (calcitriol) and synthetic vitamin D analog (paricalcitol) on oxidative stress in hemodialysis patients. Methods: This cross-sectional study was composed of 83 patients with a minimum hemodialysis vintage of one year. Patients with a history of any infection, malignancy, and chronic inflammatory disease were excluded. Oxidative markers (total oxidant and antioxidant status) and inflammation markers (C-reactive protein and interleukin-6) were analyzed. Results: A total of 47% (39/83) patients were using active or analog vitamin D. Total antioxidant status was significantly higher in patients with using active or analog vitamin D than those who did not use (p = 0.006). Whereas, total oxidant status and oxidative stress index were significantly higher in patients with not using vitamin D when compared with the patients who were using vitamin D preparation (p = 0.005 and p = 0.004, respectively). On the other hand, total antioxidant status, total oxidant status, and oxidative stress index were similar between patients who used active vitamin D or vitamin D analog (p = 0.6; p = 0.4 and p = 0.7, respectively). Conclusion: The use of active or selective vitamin D analog in these patients decreases total oxidant status and increases total antioxidant status. Also, paricalcitol is as effective as calcitriol in decreasing total oxidant status and increasing total antioxidant status in patients with chronic kidney disease.

Background: The red-crowned crane (Grus japonensis) is one of the most vulnerable bird species in the world. Mycotoxins are toxic secondary metabolites produced by fungi and considered naturally unavoidable contaminants in animal feed. Our recent survey indicated that the mycotoxins had the potential to contaminate redcrowned crane’s regular diets in China. Objective: This experiment was conducted to investigate the protective effects of mycotoxin binder montmorillonite (Mont) on growth performance, serum biochemistry and oxidative stress parameters of the red-crowned crane. Methods: 16 red-crowned cranes were divided into four groups and fed one of the following diets; a selected diet, regular diet, or the selected diet or regular diet with 0.5% montmorillonite added to the diets. The cranes' parameters of performance, hematology, serum biochemistry and serum oxidative stress were measured. Results: Consuming regular diets decreased the average daily feed intake (ADFI), levels of haemoglobin (Hb), platelet count (PLT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT), but increased the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase (CK) and lactate dehydrogenase (LDH). The supplementation of 0.5% Mont provided protection for the red-crowned crane in terms of feed intake, serum biochemistry and oxidative stress. Moreover, Mont supplementation had no adverse effect on the health of red-crowned crane. Conclusions: Taken together, these findings suggested that the addition of dietary Mont is effective in improving the health of red-crowned crane.

Intestinal tissue is highly susceptible to ischemia/reperfusion injury in many hazardous health conditions. The anti-inflammatory and antioxidant glycoprotein fetuin-A showed efficacy in cerebral ischemic injury; however, its protective role against intestinal ischemia/reperfusion remains elusive. Therefore, this study investigated the protective role of fetuin-A supplementation against intestinal structural changes and dysfunction in a rat model of intestinal ischemia/reperfusion. We equally divided 72 male rats into control, sham, ischemia/reperfusion, and fetuin-A-pretreated ischemia/reperfusion (100 mg/kg/day fetuin-A intraperitoneally for three days prior to surgery and a third dose 1 h prior to the experiment) groups. After 2 h of reperfusion, the jejunum was dissected and examined for spontaneous contractility. A jejunal homogenate was used to assess inflammatory and oxidative stress enzymes. Staining of histological sections was carried out with hematoxylin, eosin and Masson’s trichrome stain for evaluation. Immunohistochemistry was performed to detect autophagy proteins beclin-1, LC3, and p62. This study found that fetuin-A significantly improved ischemia/reperfusion-induced mucosal injury by reducing the percentage of areas of collagen deposition, increasing the amplitude of spontaneous contraction, decreasing inflammation and oxidative stress, and upregulating p62 expression, which was accompanied by beclin-1 and LC3 downregulation. Our findings suggest that fetuin-A treatment can prevent ischemia/reperfusion-induced jejunal structural and functional changes by increasing antioxidant activity and regulating autophagy disturbances observed in the ischemia/reperfusion rat model. Furthermore, fetuin-A may provide a protective influence against intestinal ischemia/reperfusion complications.
