Nitrification inhibitors may be potential management strategy to reduce N2O emissions in irrigated rice (Oryza sativa L.). A field experiment was conducted to evaluate chemically synthesized as well as locally available neem plant products on N2O emissions, from an irrigated rice at New Delhi, India. Emission of nitrous oxide (N2O) was monitored during 70 days by closed chamber method in rice (...

This study examines the controlled release behavior of both water-soluble (acetaminophen, caffeine, theophylline and salicylic acid) and water insoluble (indomethacin) drugs derived from Caesalpinia pulcherrima seed Gum isolated from Caesalpinia pulcherrima kernel powder. It further investigates the effect of incorporating diluents such as microcrystalline cellulose and lactose on caffeine rele...

We have previously shown that the flowers of neem tree (Azadirachta indica A. Juss, family Meliaceae), Thai variety, strongly induced the activity of glutathione S-transferase (GST) while resulting in a significant reduction in the activities of some cytochrome P(450)-dependent monooxygenases in rat liver, and possess cancer chemopreventive potential against chemically-induced mammary gland and...

An experiment was carried out in the field laboratory, Department of Entomology, Bangladesh Agricultural University to find out the efficacy of different botanicals and chemical insecticides against rice stem borer during the period from July to December 2013. The treatments included Neem oil, Mahogany oil, combination of Neem and Mahogany oil, Bishkatali leaf extract, Lantana leaf extract, com...

To study the effect of neem extract on the growth and viable count of foodborne and contaminated bacteria and determine its active inhibitors. Different concentrations of methanolic extracts (200 mg/ml, 150 mg/ml, 100 mg/ml, 50 mg/ml and 25 mg/ml) were prepared. One-hundred microliters of standardized test organisms was treated with solvents or extract. The extract was tested against Gram-posit...

Neem oil is often used externally as a traditional medicine in India. Its ingestion, even in small doses produces toxic effects like severe metabolic acidosis, seizures, renal failure and encephalopathy. Management is supportive and prognosis is generally good but fatalities may occur. Herein we report an unusual case of neem oil toxicity in a previously normal adult.

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...

Addictive tobacco habit, both oral use and smoking, continues to be a major public health problem despite the availability of pharmacotherapeutic cessation aids. Long lasting abstinence rates following tobacco cessation measures remain less than optimal Several alternative treatments have been studied for tobacco cessation including natural products, such as Avena sativa1, lobeline2, mint snuff...
