The purpose of this study was to compare the antibacterial properties of Azadirachta indica (neem) or Curcuma longa (turmeric) against Enterococcus faecalis with those of 5% sodium hypochlorite or 2% chlorhexidine as root canal irrigants in vitro. The activity of neem, chlorhexidine, sodium hypochlorite, or turmeric against E. faecalis was measured on agar plates using the agar diffusion method...

The present study was designed to investigate the effect of Azadirechta indica (Neem) leaf extract on restraint-induced behavioral deficits and changes in serotonin metabolism in rats. Exposure to a single stress decreased food intake, growth rate and elicited anxiogenic-like behavior on an elevated plus maze. Prior administration of neem leaf extract @ 1 ml/kg for 5 days attenuated stress indu...

Static renewal bioassay tests were conducted to evaluate the acute toxicity of two neem based biopesticides, applied widely on tea plantation namely, Nimbecidine and Neem Gold either separately as well as, in combination to the fingerlings (mean body length- 4.46 +/- 0.15 cm; mean body weight- 0.49 +/- 0.15g) of a fresh water loach, Lepidocephalichthys guntea (Hamilton Buchanan) acclimatized to...

The efficacy of different concentrations of aqueous neem leaf extract (3.12 to 50 mg/mL) on growth and citrinin production in three isolates of Penicillium citrinum was investigated under laboratory conditions. Mycotoxin production by the isolates was suppressed, depending on the concentration of the plant extract added to culture media at the time of spore inoculation. Citrinin production in f...

The National Research Institutes’ 1992 report on neem anticipated that continuing research into the components of a tree known in India as a ―village pharmacy‖ would demonstrate useful cures for various ailments, but it’s unlikely that even the most optimistic researcher could have predicted the potentially life-saving treatments being identified now for preventing or treating multiple types ca...

The Present studies was carried to evaluate the antimicrobial activity against soil microbes which causes corrosion on buried metal in acidic mediated soil by agar well diffusion using aqueous and ethanol extract of Neem leaves. These plants were subjected to solvent extraction with water and ethanol on increasing the polarity to identify and isolate the antimicrobial active materials. Crude aq...

The present study was carried out to screen and evaluate antimicrobial activity of leaf and bark extracts of Azadirachta indica. Ethanol and aqueous extract of leaves and barks of A. indica (Neem) were tested against Escherichia coli and Staphylococcus aureus which are known to be resistant to various antibiotics. Neem materials which were used during this study were collected from Bugesera dis...

Herbal medicine is an increasingly common form of alternative therapy through out the world. Consequently, herbal medicines are finding their more and more usefulness in the arena of dentistry and their armamentarium. Earlier they were limited to as an important ingredient of tooth pastes, mouthwashes and as pain reliever, but now a days they are increasingly being used in all possible treatmen...

TRIFONOVA, Z. and A. ATANASOV, 2011. Control of potato cyst nematode Globodera rostochiensis with some plant extracts and neem products. Bulg. J. Agric. Sci., 17: 623-627 An experiment was conducted under glass-house conditions to test the effects of five plants products in the form of drenches on the growth of potato and population density of potato cyst nematode Globodera rostochiensis. All t...

In a two-year study, aqueous seed extracts of the neem tree Azadirachta indica A. Juss (Meliaceae) and Bacillus thurigiensis (Bt) were evaluated in the field for the management of pests of okra, Abelmoschus esculentus (L.) Moench. The aqueous neem seed extracts were applied at the rate of 30, 50, 75 and 100 g/l and B.thurigiensis was applied at the rate 1.0 g/l of water. Actellic 25 EC, a synth...
