Abstract Objectives Vanadium has been reported to possess relevant therapeutic properties such as anti-diabetic and anti-tumoral. This study aimed at determining the effects of vanadium on experimentally induced colitis in rats. Methods Forty-five male Wistar rats (103 ± 3.90 g, n=15) were used for this study and were divided into three groups. Group 1 (Untreated control) had nothing added to their drinking, while groups 2 and 3 received sodium metavanadate at a dose of 50 and 200 mg/L respectively in their drinking water for 10 weeks. Colitis was thereafter induced by intra colonic administration of 1.50 mL of 6% acetic acid. Animals were sacrificed on day 0 (pre-induction), three- and seven-days post induction. Blood samples were collected for haematological variables and the distal 8 cm of the colon was collected for macroscopic, histological and biochemical (malondialdehyde-MDA, superoxide dismutase-SOD, catalase-CAT, glutathione peroxidase- GPx and nitrite concentration- NO) assessment. Results Low dose vanadium proved beneficial in ameliorating acetic acid-induced colitis by improving both histopathological and haematological changes. Gross observation showed a faster healing rate in vanadium treated groups (50 and 200 mg/L) compared with untreated control at day 3 (40 and 26.20 vs. 2.50%) and day 7 (80 and 66.70 vs. 42%) respectively. Vanadium also appears to exert its beneficial effects on acetic acid-induced colitis via up regulation of antioxidant enzymes (SOD, CAT, GPx) and NO while decreasing the over production of MDA. Conclusions Vanadium at small concentration functions as an essential trace element and may be able to promote healing process during ulcerative colitis.

Cell proliferation and apoptosis in the remnant rat kidney after treatment with lowdose irradiation was investigated. Material and methods. In the first group (n=9), adult male Wistar rats underwent 5/6 nephrectomy (NPX); in the second group (n=9), NPX was combined with low-dose irradiation. Rats without surgery and irradiation formed the control group (n=9). Results. Hypertension and proteinuria induced by NPX were decreased by 3-Gy irradiation. The 5/6 NPX rats showed a dramatic increase in proliferating and apoptotic cells in the glomeruli and in the distal tubules at week 2, which was significantly decreased by low-dose irradiation. Conclusion. The data demonstrate that low-dose irradiation is a factor slowing the process of chronic renal injury.

Rutin is a flavonoid of the flavonol type found in many typical plants, such as buckwheat, passion flower, apple and tea. Acrylamide (ACR) is a known industrial toxic chemical that produces neurotoxicity characterized by progressive neuronal degeneration. Rats were randomly divided into Control, ACR, Pregabalin and Rutin treated groups. Male wistar rats were treated with ACR (50 mg/kg/ i.p.) for 4 weeks which produce typical symptoms of neuropathy in rats. Pregabalin (10 mg/kg) and Rutin (50 & 100 mg/kg) were administered orally for 4 weeks after one hour of ACR administration. ACR enhanced the production of reactive oxygen species (ROS). Treatment with Rutin significantly improved neurological score. Rutinsignificantly (p<0.001) attenuated acrylamide induced oxidative stress markers. The expression of Bcl-2 was up-regulated and TNF-α, IL-6 and Bax were down-regulated by rutin treatment. From our results, it can be concluded that rutinshowed an ameliorative effect against ACR induced neurotoxicity in rats through its antioxidant, anti-inflammatory and antiapoptotic actions.

Opuntia ficus indica(family Cactaceae) is used in the treatment of a variety of conditions including metal-induced toxicity. The study reports the protective effects ofOpuntia ficus indica(CCE) against lithium carbonate-induced toxicity in rats. Nephrocardiotoxicity was induced in male Wistar rats by single dose of lithium carbonate (25 mg/kg b.w twice daily for 30 days). Aqueous extract ofOpuntia ficus indicawas administered at the dose of 100 mg/kg of b.w by gavage for 60 days. Obtained results revealed that administration of lithium carbonate caused a significant increase in serum creatinine, uric acid, and urea levels. Additionally, a significant decrease in the level of renal and cardiac SOD, CAT, and GPx activities was associated with a significant increase of MDA levels in lithium carbonate group more than those of the control. However, the treatment of experimental rats with CCE prevented these alterations and maintained the antioxidant status. The histopathological observations supported the biochemical evidences of nephrocardioprotection. CCE supplementation could protect against lithium carbonate-induced renal and cardiac injuries in rats, plausibly by the upregulation of antioxidant enzymes and inhibition of MDA to confer the protective effect.

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.
