The present study was carried out to investigate the nephroprotective effect of the ethanolic extract of Allium saralicum R.M. Fritsch (ASRMF) in mice. Thirty-five male mice were divided into five groups (n=7). Group 1 (positive control) received 1 mL/kg olive oil intraperitoneally (i.p.) and 0.5 mL distilled water orally; Group 2 (negative control) received CCl4 (50% in olive oil, 1 mg/kg; i.p.); Groups 3, 4 and 5 received CCl4 and 200, 800 and 1600 ?g/kg of ASRMF extract, respectively. The renal volume and cortex in Groups 1 and 2 were increased by 55% and 62% (p?0.001) following CCl4 administration, respectively, and were improved after ASRMF administration. The volume of proximal convoluted tubules (PCTs), glomeruli, vessels and interstitial tissue increased 80%, 150%, 83% and 64% (p?0.05), respectively, in CCl4-treated mice, and decreased significantly with 800 and 1600 ?g/kg of ASRMF. The length of PCTs and vessels increased 51% and 45% and decreased (p?0.05) with 200, 800 and 1600 ?g/kg of ASRMF, respectively. CCl4-treated mice lost 22.5% of glomeruli; the loss was inhibited significantly (p?0.05) by ASRMF. Urea and creatinine concentrations were increased (p?0.05) in CCl4-induced nephrotoxicity as compared to the controls, whereas different doses of ASRMF restored the levels of these biomarkers compared to the negative controls. In conclusion, ASRMF has a potent nephroprotective property and can improve renal structural and serum biomarkers in CCl4-induced nephrotoxicity in mice.

Menopause is a hypoestrogenic condition due to decreased function of the ovary. During menopause there is no reserved ovum in the ovary, as a result the synthesis of estrogen by the follicles does not take place. Deficiency of estrogen can lead to discomfort and decrease in the women quality of life. Therefore, supplements from natural resources to reduce menopausal symptoms will be needed. The objectives of the study were to determine the effect of mahogany seeds ethanolic extract (MSEE) on the development of uterus, bone density, and mammae gland proliferation on ovariectomized rats. Extract was made by maceration using 96% ethanol as the solvent, then the study of estrogenic effect was carried out on 30 female rats which were divided into 6 groups. Group 1 (normal control), group 2 (positive control) given estradiol dose of 0.18 mg/kg body weight (BW), group 3 (negative control) given Na-CMC 1% and group 4, 5, 6 given MSEE orally for 14 consecutive days with doses of 50, 100, 200 mg/kg BW. Data were analysed using ANOVA then continued with Tukey HSD Post Hoc test to see the differences between the treatments. The results of the study showed that MSEE was able to increase the weight of the uterus, the length of estrus phase in the estrus cycle, bone density and the mammae gland proliferation of rats. The results concluded that MSEE has phytoestrogenic effect on ovariectomized rats.Keywords: phytoestrogen, ovariectomy, uterus weight, bone density, mammae proliferation

Benign prostatic hyperplasia (BPH) is the most common benign proliferative disease among men during aging. The herbal extract of P. africanus has been used for the treatment of BPH since time immemorial. However microstructural changes of this extract to the prostate of animal or human models are still elusive. Therefore, histological and histomorphometric changes in rats with testosterone-induced BPH due to P. africanus herbal extracts were investigated. Twenty-eight male Wistar rats (200 ± 50 g) were divided into four groups each with 7 rats. Group 1 (Negative control) was given 2 ml/day of olive oil subcutaneously and 2 ml/day of normal saline intragastrically for 28 days. Three groups were induced with BPH by subcutaneous injection of testosterone propionate 3 mg/kg body weight/day for 28 days. Thereafter Group 2 (BPH) was sacrificed, while Group 3 (Positive control) and Group 4 (Treatment group) were administered with finasteride 5 mg/kg/day and P. africanus extract 400 mg/kg/day intragastrically for 28 days, respectively. BPH group revealed thickening and hyperplasia of tubular epithelium with involutions with the stroma showing large spaces and dilated blood vessels. These features were restored with P. africanus extract administration. High epithelial height, large stromal area and lower luminal area observed in the BPH were greatly reversed with P. africanus extract comparable to negative controls. Generally, P. africanus extract restored and ameliorated histological and histomorphometrical changes of the BPH-induced rat’s prostates.

The aim of this study was to compare the vertical fracture resistance of roots obturated with different root canal filling materials and sealers. Crowns of 55 extracted mandibular premolar teeth were removed to provide root lengths of 13 mm. Five roots were saved as negative control group (canals unprepared and unfilled). Fifty root canals were instrumented and then five roots were saved as positive control group (canals prepared but unfilled). The remaining 45 roots were randomly divided into three experimental groups (n=15root/group) and obturated with the following procedures: in group 1, glass ionomer-based sealer and cone (ActiV GP obturation system); in group 2, bioceramic sealer and cone (EndoSequence BC obturation system); and in group 3, roots were filled with bioceramic sealer and cone (Smartpaste bio obturation system). All specimens were tested in a universal testing machine for measuring fracture resistance. For each root, the force at the time of fracture was recorded in Newtons. The statistical analysis was performed by using Kruskal-Wallis and post hoc test. There were no significant differences between the three experimental groups. The fracture values of three experimental and negative control groups were significantly higher than the positive control group. Within the limitations of this study, all materials increased the fracture resistance of instrumented roots.

OBJECTIVE: To evaluate the in vitro ionic degradation and slot base corrosion of metallic brackets subjected to brushing with dentifrices, through analysis of chemical composition by Energy Dispersive Spectroscopy (EDS) and qualitative analysis by Scanning Electron Microscopy (SEM). METHODS: Thirty eight brackets were selected and randomly divided into four experimental groups (n = 7). Two groups (n = 5) worked as positive and negative controls. Simulated orthodontic braces were assembled using 0.019 x 0.025-in stainless steel wires and elastomeric rings. The groups were divided according to surface treatment: G1 (Máxima Proteção Anticáries®); G2 (Total 12®); G3 (Sensitive®); G4 (Branqueador®); Positive control (artificial saliva) and Negative control (no treatment). Twenty eight brushing cycles were performed and evaluations were made before (T0) and after (T1) experiment. RESULTS: The Wilcoxon test showed no difference in ionic concentrations of titanium (Ti), chromium (Cr), iron (Fe) and nickel (Ni) between groups. G2 presented significant reduction (p < 0.05) in the concentration of aluminium ion (Al). Groups G3 and G4 presented significant increase (p < 0.05) in the concentration of aluminium ion. The SEM analysis showed increased characteristics indicative of corrosion on groups G2, G3 and G4. CONCLUSION: The EDS analysis revealed that control groups and G1 did not suffer alterations on the chemical composition. G2 presented degradation in the amount of Al ion. G3 and G4 suffered increase in the concentration of Al. The immersion in artificial saliva and the dentifrice Máxima Proteção Anticáries® did not alter the surface polishing. The dentifrices Total 12®, Sensitive® and Branqueador® altered the surface polishing.

Introduction: Discoloration can be caused by intrinsic or extrinsic factors. One of the discoloration treatments is teeth whitening. Teeth whitening process usually uses chemicals such as hydrogen peroxide or carbamide peroxide which can cause side effects, namely gingival irritation. Previous research has found that malic acid in strawberries can whiten teeth. Watermelons contain greater malic acid than strawberries. Objective: To analyze the  effectiveness of 100% watermelon (Citrullus lanatus) extract on teeth whitening. Methods: The study was a laboratory experimental study with a total of 15 anterior post-extraction teeth which were discolored using black tea, divided into 3 groups. Group 1 was immersed in 100% watermelon extract, group 2 was immersed in 10% carbamide peroxide as positive control and group 3 was immersed in sterile aquades as negative control, for 56 hours, measured using a shade guide and spectrophotometer. Data were analyzed using one way Anova. Results: The 100% watermelon extract was effective for teeth whitening. There was a significant difference between 100% watermelon extract compared to negative control (p < 0.05). However, there was also a significant difference between 100% watermelon extract, and 10% carbamide peroxide gel (p = 0.003). Conclusion: The watermelon extract has the ability as teeth whitening agent. However, further study is still needed to explore this result and determine the proper concentration for teeth whitening.
