Soursop (Annona muricata L.) and gotu kola (Centella asiatica L.Urb) is a plant that can be used as a laxative medicine kidney stones. This is because of the content of bioactive compounds including flavonoids, especially the leaf section. The use of a combination of soursop leaf extract and gotu kola can improve their effectiveness in order to remove calcium kidney stones. Therefore, this study aims to determine the activity and to determine dose combination soursop leaf ethanol extract (SS) and gotu kola leaf (GK) which is effective for dissolving potassium kidney stones. Extracts prepared by maceration method using ethanol 96% then subsequently tested phytochemical screening and thin layer chromatography profiles on each extract. Results chromatogram showed the extract containing flavonoids. Testing the activity of the combination of soursop and gotu kola extract performed using seven treatments, combination 1 (SS 1% + GK 7.5% ), a combination of 2 (SS  0.5% + GK 3.75%), the combination of 3 (SS 0, 25% + GK 1.875%), single soursop leaf extract (1%), single gotu kola extract (7.5%), negative control (aquadest) and positive control (Batugin elixir). Kidney stones are then put as much as 100 mg in each treatment and incubated for 6 hours (37 ℃). Results filtrate then didestruksi and dissolved calcium levels measured using Atomic Absorption Spectrophotometer. The results showed the combination soursop leaf ethanol extract and gotu kola leaf extract with a combination of 2 (SS 0.5% + GK 3.75%) is an effective combination of the ability to dissolve calcium kidney stones in vitro.

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.

A study was carried out to screen for phytochemical constituents and assess the antioxidant and antimicrobial activities of Senna alata and Senna tora leaf extracts. The leaves were first dried at room temperature and 50°C in an oven prior to solvent extraction using ethanol and methanol. The in-vitro qualitative assays showed that both S. alata and S. tora leaf extracts contained bioactive and secondary metabolites components such as tannins, steroids, saponin, terpenoids, glycosides, flavonoids and phenols. The antioxidant activity and capacity test were carried out by conducting free radical of 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity and Ferric reduction antioxidant plasma (FRAP) assays. Both assays showed S. tora leaf extract has higher antioxidant capacity than S. alata leaf extract. The efficacy of these leaf extracts were tested against skin pathogens through agar well diffusion method. S. alata extract showed an inhibition zone (1.15 – 1.59 mm) against Pseudomonas aeruginosa while S. tora extracts exhibited a strong antimicrobial activity against S. epidermidis (inhibition zone of 12 – 16.94 mm) followed by P. aeruginosa (inhibition zone of 1 – 1.59 mm). Nonetheless, no inhibition zone was observed for S. aureus by both leaf extracts. The phytochemicals and antioxidant constituents as well as inhibitory potential on skin pathogens possessed by S. alata and S. tora leave highlighted their potential utilization in the development of natural drugs or cosmetics to treat skin related diseases or infections.

Streptococcus pyogenes is one of the pathogenic bacteria that causes pharyngitis. Natural treatment to overcome these problems is to use cardamom seeds. The purpose of this study was to test the antibacterial activity, determine the concentration of inhibitory zone and phytochemical compounds from  ethanol 96% extract of Java cardamom seeds (Amomum compactum Soland. Ex Maton) against Streptococcus pyogenes. The method is used   solid dilution and paper disc diffusion method. The solid dilution method is used for the Minimum Inhibitory Concentration (MIC) test with a concentration of 1.25%, 2.5%, 5% and 7.5% while the paper diffusion method is used for the Inhibition zone Diameter (IZD)  using five treatments namely three concentrations of ethanol 96% extract of Java cardamom seeds (7.5%, 10% and 12%), one positive control of amoxicillin 0.01 mg/mL and one negative control of sterile distilled water. IZD data were  analyzed using ANOVA with a confidence level of 95% and α = 0.05 and Duncan's further tests to determine differences between treatments. The results showed that the MIC  was at a concentration of 7.5% while for the IZD test which had the highest activity there was a concentration of 12% with an average inhibition diameter of 12.03 ± 0.14 mm. In addition, ethanol 96% extract of Java cardamom seeds contain alkaloids, flavonoids, terpenoids and tannins which function in antibacterial activity.
