The present study is an effort to identify a potent chemopreventive agent against various diseases (including cancer) in which oxidative stress and cell proliferation plays an important causative role. This study was designed to investigate the effect of gallic acid against ferric nitrilotriacetic acid (Fe-NTA)-induced carcinogen/drug metabolizing phase I and phase II enzymes, anti-oxidative parameters, kidney markers, tumour promotion markers and lipid peroxidation (LPO) in kidney of male Wistar rats. Fe-NTA (9 mg Fe/kg body weight, intraperitoneally) caused significant depletion in the detoxification and antioxidant enzyme armoury with concomitant elevation in renal LPO, serum creatinine, blood urea nitrogen, hydrogen peroxide generation, ornithine decarboxylase activity and [3H]thymidine incorporation into renal DNA. However, pretreatment of animals with gallic acid (10 and 20 mg/kg body weight) resulted in a significant decrease in the levels of the parameters measured (P < 0.001). Renal glutathione content (P < 0.001), glutathione metabolizing enzyme (P < 0.001) and antioxidant enzyme levels were also recovered to a significant level (P < 0.001). The enhanced reduced glutathione level and enzyme activities involved in xenobiotic metabolism and maintaining antioxidant status of cells are suggestive of a chemopreventive efficacy of gallic acid against Fe-NTA-mediated oxidative stress, toxicity and cell proliferative response in Wistar rats.

Lead is a heavy metal found in earth’s crust. It is a widespread and insidious environmental toxin known as a severe and aggressive contaminant to human and animal organisms’ health status. This work is aimed at evaluating the effect of aqueous extract of Ocimum gratissimum (OG) on lead induced changes in the thymus of adult albino wistar rats. Thirty five male Wistar rats were used in the study and were randomly divided into seven groups with five rats in each group. The rats in Group one (G1) served as the Control and received distilled water. Group 2 received 120 mg/kg body weight (bwt) of lead acetate, G3 received 375 mg/kg bwt of OG only. G4 received 120 mg/kg bwt of lead acetate and OG extract at 375 mg/kg bwt., G5 received 120 mg/kg bwt of lead and OG at 750 mg/kg bwt. G6 received 375 mg/kg bwt of OG in two weeks followed by 120 mg/kg bwt of lead acetate for one week, while G7 received 120 mg/kg bwt of lead acetate and Vitamin C at 11900 mg/kg. All the administrations were carried out orally for twenty one (21) days. At the end of the administration, the rats were fasted for 24 hours. They weighted and humanely sacrificed via cervical dislocation. The thymus were harvested in all the groups and prepared for histological studies using routine haematoxylin and eosin (H&E) staining techniques. The result of the present study shows that lead possessed a distortive effect in the histoarchitecture of thymus of the wistar rat in G2 when compared with G1. Treatment of these experimental animals with vitamin C prove to posses more ameliorative effect in restoring the histoarchitecture on lead toxicity in the thymus closed to normal than OG. Therefore, it is suggested that aqueous extract OG can act via the same pathway as vitamin C, in maintaining the normal histological structures of the thymus of adult albino wistar rat exposed to lead toxicity.

Background: Trevo is a nutritional supplement with numerous bioactive natural products, with detoxifying and antioxidant properties. The purpose of this study was to investigate the ability of Trévo to protect against oxidative stress induced by lead in the kidneys of male Wistar rats. Methods: Thirty-five healthy male Wistar rats were divided into five groups of seven rats each, using a randomized design. I=control; II=15 mg/kg of lead acetate (PbA); III=2 ml/kg of trevo+PbA; IV=5 ml/kg of trevo+PbA; V=5 ml/kg of trevo. Animals were treated with trevo for five days before co-administration with lead intraperitoneally for 10 consecutive days. Animals were sacrificed 24hr after the last administration, blood samples were collected via cardiac puncture, and processed for assessment of urea, creatinine, and uric acid (UA), while the kidney samples were excised and processed for the following biochemical assays: Malondialdehyde (MDA), Glutathione-S-Transferase (GST), Catalase (CAT), Superoxide Dismutase (SOD), and Reduced Glutathione (GSH). Results: Injection of PbA caused a significant increase in the serum levels of urea, creatinine, and uric acid, and a significant increase (P<0.001) in the MDA concentration, and decreases in GSH concentration, CAT, SOD, and GST activities (P<0.05) as compared to the controls. Pretreatment with trevo prevented the oxidative stress induced by lead acetate in the kidney tissue samples and improve the renal function. The protective effect was evident at 5 ml/kg of trevo. Conclusion: The results showed that trevo was nephroprotective against lead toxicity and the activity might be linked to the presence of numerous antioxidant phytochemicals present in trevo.

AbstractObjectivesAdansonia digitata L. is popularly known for the management of various neurological diseases in ethno-medicine. Studies have shown that lead toxicity is a possible risk factor for early onset of neurodegenerative disease. Hence, this study was designed to evaluate the effect of A. digitata aqueous leaf extract (ADALE) against lead-induced oxidative stress and histo-architectural changes in the prefrontal cortex of adult Wistar rats.MethodsSaline (10 mL/kg), ADALE (500 and 1000 mg/kg) and EDTA (55 mg/kg) were pretreated orally 30 min prior to lead acetate (LA) (120 mg/kg) administration to male Wistar rats (n=7) for 21 days. Thereafter, standard biochemical (superoxide dismutate, catalase, glutathionxe and malondialdehyde), histological (H&E) and histochemical assessment (crystyl fast violet stain for nissil substance) were carried out in the prefrontal cortex.ResultsADALE significantly (p<0.05) reversed LA-induced oxidative stress, as evidenced by increased catalase, superoxide dismutase and oxidized glutathione levels, and decreased malondialdehyde concentration in the prefrontal cortex. Also, the increase chromatolysis and neuronal pyknosis of the pyramidal neurons of the prefrontal cortex were significantly attenuated by ADALE.ConclusionsThe result of this study showed that A. digitata aqueous leaf extract attenuated lead acetate-induced cortical neurodegeneration via inhibition of oxidative stress.

Progressive Renal Insufficiency

Under experimental conditions severe reduction of renal mass results in the hyperfiltration of the remaining nephrons leading to a progressive renal insufficiency. Similar changes are observed in patients with various renal disorders associated with a loss of the functioning nephrons. The progression of renal damage is accelerated by high protein and phosphate intake, and may be modified by the dietary restrictions.We studied 50 five-sixth nephrectarrized male Wistar rats on a standard diet (Rodent Laboratory Chow 5001 Ralston Purina Co., Richmond, Indiana; containing 23.4% protein) over a 20 week period.

Abstract. Physical exercise increases free radicals production; antioxidant supplementation may improve the muscle fiber’s ability to scavenge ROS and protect muscles against exercise-induced oxidative damage. This study was designed to examine the effects of all-trans resveratrol supplementation as an antioxidant to mediate anti-oxidation and lipid per-oxidation responses to exercise in male Wistar rats. Sixty-four male Wistar rats were randomly divided into four equal number (n = 16) including training + supplement (TS), training (T), supplement (S) and control (C) group. The rats in TS and S groups received a dose of 10 mg/kg resveratrol per day via gavage. The training groups ran on a rodent treadmill 5 times per week at the speed of 10 m/min for 10 min; the speed gradually increased to 30 m/min for 60 minutes at the end of 12th week. The acute phase of exercise protocol included a speed of 25 m/min set to an inclination of 10° to the exhaustion point. Superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) activity, non-enzymatic antioxidants bilirubin, uric acid, lipid peroxidation levels (MDA) and the total antioxidant capacity (TAC) were measured after the exercise termination. The data were analyzed by using one-way ANOVA. The result showed that endurance training caused a significant increase in MDA level [4.5 ± 0.75 (C group) vs. 5.9 ± 0.41 nmol/l (T group)] whereas it decreased the total antioxidant capacity [8.5 ± 1.35 (C group) vs. 7.1 ± 0.55 mmol/l (T group)] (p = 0.001). In addition, GPx and CAT decreased but not significantly (p > 0.05). The training and t-resveratrol supplementation had no significant effect on the acute response of all variables except MDA [4.3 ± 1.4 (C group) vs. 4.0 ± 0.90 nmol/l (TS group)] (p = 0.001) and TAC [8.5 ± 0.90 (C group) vs. 6.6 ± 0.80 mmol/l (TS group)] (p = 0.004). It was concluded that resveratrol supplementation may prevent exercise-induced oxidative stress by preventing lipid peroxidation.
