Abstract Background The objective of this study was to evaluate protective effect of grape and apple juices against toxicity induced by cadmium in the kidney of rats. Methods A total of 20 male-Wistar rats were distributed into four groups (n=5): Control group: animals received an intraperitoneal (i.p.) injection of 0.9% saline solution and after 15 days, 1 mL of water was administered for 15 days, via gavage; Cadmium group: animals received an intraperitoneal injection of cadmium chloride (1.2 mg/kg) and after 15 days, 1 mL of water was administered for 15 days via gavage; Cadmium+Grape Juice: animals received an i.p. injection of cadmium chloride (1.2 mg/kg), and after 15 days, 0.8 mL of grape juice was administered for 15 days, via gavage; Cadmium+Apple Juice: animals received i.p. injection of cadmium chloride (1.2 mg/kg) and after 15 days, 1.0 mL of apple juice was administered for 15 days, via gavage. Results Histopathological analysis revealed severe tubular lesion and necrosis in the group exposed to cadmium, while animals exposed to grape or apple juices showed a significant reduction of tissue injury. 8-OHdG immunoexpression, DNA damage, cytochrome C and catalase gene expressions and Toll like signaling pathway (TLR2, and pIKKα/β) decreased in animals treated with grape juice when compared to cadmium group. Conclusion Taken together, we conclude that grape and apple juices had a protective effect by means of antioxidant, antigenotoxic actions and for promoting tissue regeneration in the kidney of rats following cadmium intoxication.

PURPOSE: To analyze the action of gangliosides in peripheral nerve regeneration in the sciatic nerve of the rat. METHODS: The sample was composed of 96 male Wistar rats. The animals were anaesthetized and, after identification of the anaesthesic plane, an incision was made in the posterior region of the thigh, followed by skin and muscle divulsion. The right sciatic nerve was isolated and compressed for 2 minutes. Continuous suture of the skin was performed. The animals were randomly divided into two groups: the experimental group (EG), which received subcutaneous injection of gangliosides, and the control group (CG), which received saline solution (0.9%) to mimic the effects of drug administration. RESULTS: No differences were observed between the experimental and control groups evaluated on the eighth day of observation. At 15 and 30 days the EG showed an decrease in Schwann cell activity and an apparent improvement in fibre organization; at 60 days, there was a slight presence of Schwann cells in the endoneural space and the fibres were organized, indicating nerve regeneration. At 15 and 30 days, the level of cell reaction in the CG had diminished, but there were many cells with cytoplasm in activity and in mitosis; at 60 days, hyperplastic Schwann cells and mitotic activity were again observed, as well as nerve regeneration, but to a lesser extent than in the EG. CONCLUSION: The administration of exogenous gangliosides seems to improve nerve regeneration.

Background and Objectives: Radiation enteritis is a common side effect after radiotherapy for abdominal and pelvic malignancies. The aim of the present study was to investigate the protective effect of melatonin, known for its free radical scavenging ability, against radiotherapy-induced small intestinal oxidative damage. Materials and Methods: Thirty male Wistar rats were randomly assigned to six groups (5 rats in each) as follows: Group I (control group) rats received neither radiation nor melatonin; group II rats received only 8 Gy single dose of gamma radiation to their abdomen and pelvis regions; group III (administered with only 50 mg/kg melatonin); group IV (administered with only 100 mg/kg melatonin); group V (50 mg/kg melatonin + 8 Gy radiation), group VI (100 mg/kg melatonin + 8 Gy radiation). All rats were sacrificed after 5 days for biochemical assessments of their intestinal tissues. Results: Treatment with melatonin post irradiation significantly reduced malondialdehyde (MDA) levels as well as increased both superoxide dismutase (SOD) and catalase (CAT) activities of the irradiated intestinal tissues. In addition, melatonin administration with different doses pre irradiation led to protection of the tissues. Moreover, the 100 mg/kg dose was more effective compared to 50 mg/kg. Conclusions: The results of our study suggest that melatonin has a potent protective effect against radiotherapy-induced intestinal damage, by decreasing oxidative stress and increasing antioxidant enzymes. We recommend future clinical trials for more insights.

Background:Ganoderma lucidum (Leyss. Ex. Fr) Karst is a basidiomycete mushroom that has been used for many years as a food supplement and medicine. In Brazil, National Health Surveillance Agency (ANVISA) classified Ganoderma lucidum as a nutraceutical product. The objective of the present work was to observe the effects of an extract from Ganoderma lucidum in rats treated with streptozotocin, and an agent that induces diabetes. Method: Male Wistar rats were obtained from the animal lodging facilities of both University Nove de Julho (UNINOVE) and Lusiada Universitary Center (UNILUS) with approval from the Ethics Committee for Animal Research. Animals were separated into groups: (1) C: Normoglycemic control water; (2) CE: Normoglycemic control group that received hydroethanolic extract (GWA); (3) DM1 + GWA: Diabetic group that received extract GWA; and (4) DM1: Diabetic group that received water. The treatment was evaluated over a 30-day period. Food and water were weighted, and blood plasma biochemical analysis performed. Results: G. lucidum extract contained beta-glucan, proteins and phenols. Biochemical analysis indicated a decrease of plasma glycemic and lipid levels in DM rats induced with streptozotocin and treated with GWA extract. Histopathological analysis from pancreas of GWA-treated DM animals showed preservation of up to 50% of pancreatic islet total area when compared to the DM control group. In plasma, Kyn was present in diabetic rats, while in treated diabetic rats more Trp was detected. Conclusion: Evaluation from G. lucidum extract in STZ-hyperglycemic rats indicated that the extract possesses hypoglycemic and hypolipidemic activities. Support: Proj. CNPq 474681/201.

Diabetes mellitus is the most common endocrine disorder worldwide and it is usually along with complications such as retinopathy, neuropathy, nephropathy, and cardiovascular disease. The prevalence of diabetes is increasing and its treatment has created concerns in society. The use of herbal medicine can be helpful in the management of diabetes mellitus. The aim of this study was to investigate the protective effect of marigold hydroalcoholic extract under diabetes condition. A total of 36 male Wistar rats were randomly divided into four groups: normal control group, diabetic control group, and groups treated with 250 or 500 mg/kg hydroalcoholic extract of marigold flower during four weeks. At the end of the study, the rats were anesthetized with ketamine/xylazine, and sampling was performed through cardiac puncture. The results showed that treatment with marigold improved body weight. In addition, we determined that marigold normalized the level of CK-MB, total CK, amylase, and lipase in a dose-dependent manner. Probably these effects resulted from antioxidant property of marigold; thus we suggest that marigold flower can be useful for reduction of diabetes complication.

Experimental Periodontitis

The resveratrol is a polyphenol known for its health benefits, which includes the ability to interfere in the osteoblastogenesis, which may foster adverse immunomodulators effects in the host response to periodontal disease. In the present study we evaluated the appearance of periodontal tissues of rats with experimentally induced periodontitis, by using resveratrol. Twenty-four male Wistar rats were used, in which half of the animals received a ligature around the first lower molars, then forming the groups with experimental periodontitis. Next, four groups were created: 1) Control Group (CON); 2) The Ligature Group (LIG); 3) Group Resveratrol (RSV); 4) Ligature-Resveratrol Group (LIG-RSV). The animals of the Resveratrol groups were daily dosed with 10 mg/kg of body weight of polyphenol orally, during four weeks. After 105 days of experimental period, euthanasia was performed. The results showed a significantly lower alveolar bone loss (p<0.05) in animals that received resveratrol, and still, the polyphenol was able to reduce concentration of interleukin 17 (IL-17) in the groups dosed with it. Our conclusion is that dosing rats with experimental periodontitis with resveratrol could cause a protective effect on the alveolar bone loss, in addition to act positively on the IL-17.

The aim was to study the protective effect of ethanolic extract of Achillea millefolium on acute vascular injuries induced by cisplatin in liver, heart and renal tissues 24 hour after administration and using histopathological surveys in wistar rats. 24 adult male wistar rats were randomly divided into four groups. Group I (control group) received physiological saline for 10 days. Animals of group II had single dose of injection of CP (cisplatin) (6 mg/kg, IP) on the ninth day. Group III received Achillea millefolium extract (250 mg/kg, gavage) for 10 consecutive days. Group IV had both Achillea millefolium extract (250 mg/kg, gavage) for 10 consecutive days and a single dose of injection of CP (6 mg/kg, IP) on the ninth day. Kidney, liver and heart organs were collected on 10th day from sacrificed rats and subjected to histopathological analysis. Then the possible histopathological vascular effects of cisplatin on liver, heart, kidney tissues and the protective effect of Achillea millefolium extract was analysed. Obtained data showed the vascular injuries in CP group as congestion of cardiac capillaries (p=0.00) and interstitial edema (p=0.03). In the kidney, shrinkage of glomeruli (p=0.04), widening of Bowman's space (p=0.04), dilatation of cortical capillaries (p=0.01) were significantly altered. The findings of liver organ were increased sinusoidal space (p=0.00) and infiltration of neutrophils in portal space (p=0.01). Pretreatment with ethanolic extract of Achillea millefolium could attenuate these vascular injuries. Briefly, 24 hour after single injection of cisplatin the inflammatory process was seen in vital organs and administration of Achillea millefolium could mitigate these side effects.

In recent years more attention has been given to herbal drugs in the treatment and prevention of drug toxicity because of the harmful effects of chemical drugs. In this study, directed for this purpose, research was conducted on the protective effect of hydro-ethanolic extract of saffron petals (SPE) against acetaminophen (APAP) induced acute nephrotoxicity. Twenty-four male Wistar rats were distributed into four groups of six each. Group I, as a control group, received normal saline (0.09%) orally (PO). Group II, as an intoxicated group was treated with APAP, PO (600 mg/kg). In the groups III and IV, SPE in a dose of 10 and 20 mg/kg along with APAP (600 mg/kg) was administered, respectively. At the end of the trial (8th day), blood was taken from the heart of rats for assessment of biochemical parameters and the right kidney was placed in 10% buffered formalin for histopathological evaluations. In the APAP treatment group, higher serum creatinine and uric acid were observed. SPE in a dose of 20 mg/kg significantly reduced serum creatinine and uric acid. In pathologic evaluation, a dose of 20 mg/kg of SPE prevented the kidney injuries induced by APAP. Tissues changes were in accordance with biochemical findings. It is likely that the SPE contributed to the prevention of acute nephrotoxicity induced by APAP.

Background: The protective effect of mistletoe extract (Helixor®, HLX) against methotrexate (MTX)-induced acute oxidative stress and nephrotoxicity in rats was evaluated by histological and biochemical methods as well as the comet assay. Material and Methods: 32 female Wistar albino rats were divided into 4 groups: control group, HLX group (5 mg/kg body weight (bw), days 1-10, intraperitoneally (i.p.)), MTX group (10 mg/kg bw, days 7, 8, and 9, i.p.), and MTX + HLX group (10 mg/kg bw, days 7, 8, and 9, i.p. + 5 mg/kg bw, days 1-10, i.p.). At the end of the experiment, the glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), nitric oxide (NO), and myeloperoxidase (MPO) levels were measured, and a histopathological analysis and comet assay were carried out. Results: MTX induced renal oxidative stress and nephrotoxicity in the rats. Pretreatment with HLX significantly improved the renal GSH-Px and SOD activities in the MTX + HLX group compared to the MTX group. The decrease in the NO and MPO levels in the rat groups pretreated with HLX was not significant. The histochemical evaluation revealed that HLX provided significant improvement in the MTX-induced renal degenerative changes, including tubule distension, interstitial inflammation, perirenal inflammation, glomerular congestion, glomerular degeneration, and parenchymal hemorrhage, in the MTX + HLX group compared to the MTX-administered group. According to the comet assay, pretreatment with HLX lowered the MTX-induced DNA damage in endogenous lymphocytes, although not significantly. Conclusion: This study demonstrated that HLX administration markedly reduced the MTX-induced acute oxidative stress and nephrotoxicity in rats through its antioxidant and anti-inflammatory properties.

Background. This study was performed to evaluate the anti-hyperthyroidal effects and action mechanism of Scutellaria baicalensis Georgi (SB), a medicinal herb, on levothyroxine (LT4)-induced hyperthyroidal rats. Methods. Male Wistar rats were divided into five groups, namely, euthyroidal normal group (Normal), hyperthyroidism control group (Control), hyperthyroidism plus PTU-treated group (PTU) as a positive control, hyperthyroidism plus 400 mg/kg SB-treated group (SB400), and hyperthyroidism plus 800 mg/kg SB-treated group (SB800). The rats in groups other than Normal were injected with LT4 for 2 weeks to induce hyperthyroidism and then were administrated each treatment for 2 weeks. Clinical symptoms and biomarkers related to hyperthyroidism were examined, and the gene expressions related to the regulation of thyroid hormone were determined. Results. Compared with the Control group, pulse rate, serum T3, T4, triglyceride, thyroid follicle size, and the deiodinase 1 (Dio1) gene expression were significantly reduced in the SB and PTU groups. Serum TSH and the thyroxine-binding globulin (Tbg) gene expression were significantly increased in the SB and PTU groups. Conclusions. These results suggest that SB might suppress T3, T4, and adrenergic activity by modulating Dio1 and Tbg expression, and therefore, SB could be an alternative therapy for hyperthyroidism.
