Neem biodiesel is currently being explored as a future biofuel and was extracted chemically from the vegetable oil. Many of its properties are still under investigation and our aim was to study its noxious-gas emission profiles from blends with regular petroleum diesel. The distinct advantage of a real-time study is acquisition of in situ data on the combustion behavior of gas components with a...

We report an unusual case of neem oil poisoning in a previously normal 5 year old child. The child presented with refractory seizures and was having metabolic acidosis. Late neurological sequelae in the form of auditory and visual disturbances, and ataxia were present.

Liver weight and function also are often used as the “canary in the mine” to test for adverse effects of chemical compounds and drugs. The largest single gland in the body and the secondlargest organ, the liver filters about a quart of blood every minute, detoxifying blood by filtering toxins and other chemicals from it. When possible, it converts toxics to less harmful chemicals through variou...

activity of fresh neem leaf juice to immobilize, anaesthetize and fatal effect were studied against two live fish species, anabas testudineus and channa punctatus. the concentrations, 5, 10, 15 and 20% of neem leaf juice affected both the species, but a.  testudineus was found to be comparatively more susceptible to the treatment  than c.  punctatus . the time required to immobilize were 4 to >...

Antioxidants are compounds that protect cells against reactive oxygen cells – or free radicals -in the body. Although they are created as part of the body’s normal metabolic functions, free radicals react with other cells and may interfere with their ability to function. Free radicals are believed to play a role in many health conditions, ranging from cancer and atherosclerosis to wrinkles caus...

Morphological changes of a toxigenic isolate of Aspergillus parasiticus cultured in the presence of aqueous leaf and seed extracts obtained from neem, Azadirachta indica A. Juss (syn. Melia azadirachta L.), a potent inhibitor of aflatoxin biosynthesis, was studied. Mycelial samples obtained from A. parasiticus cultures exposed to an effective concentration of the leaf and seed extracts (50% v/v...

Department of Biotechnology, Gulbarga University, Gulbarga 585106, Karnataka, India. [email protected] and [email protected] ABSTRACT: In this experiment the seed oils of 30 Neem (Azadirachta indica. A. juss) biotypes were screened and evaluated for their physio-chemical parameters for oil content, biodiesel yield, density, viscosity, iodine value , free fatty acid, saponification ...

Drinking water is often the main source of fluoride intake by humans, especially in areas where their concentrations in groundwater and/or surface water is high. Endemic fluorosis is present in at least 20 states of India, affecting more than 65 million people including 6 million children. Fluoride ion (F) concentrations in India’s groundwater vary widely, ranging from 0.01 mg/L to 48 mg/L. Def...

Herbal drug development includes various steps, starting from a passport data on raw materials, correct identification, pharmacognistic and chemical quality, standardization, safety and randomized clinical trials. Addressing standardization is vital and needs broader consideration. Adulteration in market samples and availability of sub-standard products is one of the greatest drawbacks in promo...

Millingtonia hortensis Linn. (Bignoniaceae) commonly known as Cork tree, Akash neem, Neem chameli. It is an important medicinal plant in Southern Asia ranging from India, Burma, Thailand and Southern China. Cultivated in most parts of India in gardens and avenues. It can grow up to 25 meter tall. Flowers have very rich and pleasant scent, used in the treatment of asthma, sinusitis, cholagogue, ...
