Abstract

Background: When left unchecked, dental pathogens cause chronic diseases like periodontitis and dental caries that lead to the irreversible loss of tooth structure. However, with proper prophylactic measures, we can inhibit the excessive proliferation of pathogenic oral flora. The aim of this study was to examine the plausible antibacterial potential of silver nanoparticles synthesized using neem and Aloe vera against four dental pathogens - Streptococcus mutans, Staphylococcus aureus and the Enterococcus and Pseudomonas species.

Materials and Method: Leaves of Azadirachta indica and Aloe vera were made into a filtered herbal formulation. A metallic solution of silver nitrate was added to it and the conjunction was kept in an orbital shaker for the synthesis of nanoparticles. After centrifugation, the resultant pellet was powdered. The agar well diffusion method was used to determine the antibacterial efficacy of Ag-NPs. Fresh bacterial suspensions of Staphylococcus aureus, Streptococcus mutans, the Enterococcus and the Pseudomonas species were dispersed on the surface of Muller-Hinton agar containing plates. Ag-NP concentrations of (25, 50 & 100) μl were incorporated into the wells and the plates were then incubated at 37°C for 24 hours. Antibiotics were used as a positive control. The zone of inhibition was recorded for each plate

Results: A colour change was observed after the synthesis of Ag-NPs. The prepared particles were then characterised by a peak seen at 425 nm in UV-vis-spectroscopy. The zone of inhibition increased in size with an increase in Ag-NP concentration. They increased in the order of: Staphylococcus aureus, the Enterococcus species, Streptococcus mutans and the Pseudomonas species - with Staphylococcus aureus being the smallest and the Pseudomonas species being the largest.

Conclusion: Ag-NPs synthesized using neem and Aloe vera is an effective antibacterial agent against Streptococcus mutans and the Pseudomonas species. It is eco-friendly, rapid, easy to synthesize and effective. These Ag-NPs are a non-toxic solution for multiple-drug resistant bacteria.

Abstract

Introduction: Acacia catechu has a great importance due to its medicinal properties. It is a historical plant; widely used in traditional medicine especially in Asia. The bark of this plant is strong antioxidant, astringent, anti-inflammatory, anti-bacterial and antifungal in nature. It is used as mouthwash for mouth, gum, sore throat, gingivitis, dental and oral infections. It is also helpful in numerous women related problems. It also has abundant anti-microbial properties. This study aims at evaluating the physicochemical profile of Acacia catechu bark extract in order to make optimum use of the extract for therapeutic purposes.

Materials and Method: The plant material of Acacia catechu was shade dried at a temperature range of 20° to 30° C for about 2 weeks. The dried sample was then powdered in a grinding mill. The obtained powder was used for physico chemical analysis and for extraction using solvents.

Results: Ash value was found to be 12.7%. Acid insoluble & soluble content of the plant material was found to 1.67 & 6.26 %. The percentage weight of loss on drying or moisture content was found to be 7.245%. Extractive values found, are tabulated for different solvent systems. Ethanol 95 % showed 2.436 %.

Conclusion: Acacia catechu was characterized on the basis of the physicochemical parameters. The present work will, thus, provide helpful information on the quality of these herbal materials to ensure genuineness, safety and efficacy prior incorporation in pharmaceutical formulations.

Abstract

Aim: The aim is to study the interaction of Indole alkaloids against 2 oral carcinoma drug target by insilico docking using iGemdock tool.

Background: In this generation, technology has become so advanced that we are able to now achieve what was believed 20 years ago to be impossible. One such advancement is the in silico interactions. It is a virtual screening which enables us to bind two compounds and check the affinity of the binding. This helps us to first screen the activity of the two compounds before money, time and energy is spent in manually performing the activity and then arriving at a failure. We will be able to concentrate on the compounds which show us positive results in the in silico interactions, thus helping us in conserving time, expenditure and energy. Materials &

Method: The Oral carcinoma drug targets were identified by literature search and its 3D structure was downloaded from RCSB PDB (Protein Data Bank), which is a crystallographic database for the three-dimensional structural data of large biological molecules.

Results: From the above analysis it shows that ajmalicine shows good interaction with both the receptors also shows best fitness energy.

Abstract

Introduction: Drug abuse is an extreme desire to obtain and use increasing amounts of one or more substances. Drug abuse indicates the following risk factors for developing drug abuse problems include poor relationships with parents, inadequate supervision over adolescent activities, poor achievement in schools and so on.

Materials & Method: An online survey comprising 17 questions was administered to the participants of age group 14-19.The results are statistically analysed.

Results and Discussion: From the survey conducted, it is analysed that 67%of the adolescents have attended many drug awareness programmes. 45% of them say that alcoholism and drug addiction are genetically inherited.

Conclusion: The abuse of alcohol and drugs has resulted in significant morbidity and mortality among adolescents worldwide.School-based health centers should have the capacity to counsel students who are in need of such treatment plans and connect students to available community resources.
