BACKGROUND E. faecalis is the predominant micro-organism recovered from root canal of the teeth where previous endodontic treatment has failed. Thorough debridement and complete elimination of micro-organisms are objectives of an effective endodontic treatment. For many years, intracanal irrigants have been used as an adjunct to enhance antimicrobial effect of cleaning and shaping in endodontic...

Pseudomonas aeruginosa is well known for its ability to form biofilm on indwelling medical devices. These biofilms are difficult to remove because of their high tolerance to conventional antibiotics. Therefore, there is a need to look for alternative agents such as medicinal plants, which can eradicate or inhibit biofilm effectively. This study evaluated the role of neem in inhibiting biofilm f...

This study was conducted to investigate the preliminary environmental and mammalian toxicology of neem oil, temephos and chlorpyriphos-methyl/fenitrothion. Culex pipiens, Daphnia magna and Gambusia affinis were used to study environmental impact. A high level of toxicity was observed, with slight differences between organisms. The emulsifiers individually also displayed toxicity towards the tes...

Fish and other organisms are affected by pesticides which pollute the natural water through agricultural runoff. The aim of this study was to determine the acute toxicity of botanical pesticide, neem gold, and two synthetic pesticides, permethrin and monocrotophos, which are extensively used in agricultural farms. The mortality rate of Cyprinus carpio was monitored under laboratory conditions f...

In present study, the comparative in vitro free radical scavenging activities of methanol extracts from three indigenous medicinal plants viz. Amla, Bitter gourd and Neem were evaluated by 1, 1-diphenyl-2-picryl-hydrazil (DPPH) radical scavenging method. Ascorbic acid was used as the reference. All of the plant extracts exhibited promising antiradical effects in a concentration dependent manner...

The losses of nitrogen (N) fertilizer applied to the soil microenvironment reduce its efficiency. Different strategies like use polymer coating and chemical nitrification inhibitors had been employed N losses. But these are very expensive. Thus, a study was conducted investigate effects different concentrations Parthenium extract, neem oil, acidulated cow dung compost extract on dynamics in soi...

Root-knot nematode is one of the significant plant-parasitic nematodes in cucumber (Cucumis sativus L.). Considering its destructive potential, studies were carried out on effect organic amendments and their integration with chemicals upon root-knot pots (2016–17) infested field (2017–18), at research farm Punjab Agricultural University, Ludhiana, Punjab. Among amendments, mustard cake treatmen...

Neem (Azadirachta indica L.) leaf has been widely used in ayurvedic system of medicine for fertility regulation for a long time. The molecular mechanism by which neem leaf regulates female fertility remains poorly understood. Animal studies suggest that aqueous neem leaf extract (NLE) induces reactive oxygen species (ROS) - mediated granulosa cell apoptosis. Granulosa cell apoptosis deprives oo...

the present work aimed at studying growth pattern and carcass traits in pearl grey guinea fowl fed on dietary neem (azadirachta indica) leaf powder (nlp) over a period of 12 weeks. day old guinea fowl keets (n=120) were randomly assigned to four treatment groups, each with 3 replicates. the first treatment was designated as control (t0) in which no supplement was added to the feed, while in tre...

PURPOSE To determine the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) for the extracts of the leaves and seeds of the plant Azadirachta indica against various dermatophytes. METHODS Clinical isolates of dermatophytes(Trichophyton rubrum, Trichophyton mentagrophytes and Microsporum nanum) were treated with extracts of leaves and seeds of the plant Azadirach...
