Many studies have documented that patterns of species composition change after gap creation, but few have addressed the processes responsible for this change. The idea of competitive reduction, that disturbance removes biomass, reducing competitive intensity and allowing competitively inferior fugitive species to colonize, has been widely accepted but rarely tested. We suggest an alternative hy...

My talk will focus on the brain mechanisms of addiction with a particular emphasis on the use of brain imaging [both PET and MRI]. I will discuss the latest research in relation to the neurotransmitter mechanisms of addiction and show how we can develop imaging techniques to explore the modes of actions of existing and novel treatments for addiction

The present study deals with the pharmacognostical studies on Morinda tinctoria.(Roxb). The leaves of M.tinctoria were shade dried and mechanically powdered after keeping them in an oven at 35oC for 24 hours. These powdered materials were used for further physiochemical, phytochemical and fluorescent analysis. The leaves contains total ash value is 31%, acid insoluble ash and acid soluble ash v...

Wrightia tinctoria is a constituent of several ayurvedic preparations against skin disorders including psoriasis and herpes, though not yet has been explored for anticancer potential. Herein, for the first time, we report the significant anticancer properties of a semi-purified fraction, DW-F5, from the dichloromethane extract of W. tinctoria leaves against malignant melanoma. DW-F5 exhibited a...

The objective of this study was to evaluate the free radical scavenging potential and high performance thin layer chromatography (HPTLC) fingerprinting of Indigofera tinctoria (I. tinctoria). Phytochemical analysis was carried out using standard methods, and free radical scavenging activity of the plant was determined using 2,2-diphenyl-1-picrylhydrazy (DPPH), nitric oxide (NO) and superoxide a...

Flavonoids are widely distributed in Plant Kingdom that act as free radical scavengers and play a vital role in combating various diseases through their antioxidant property. An attempt was made to evaluate the antioxidant property of free and bound flavonoids present in Wrightia tinctoria (Roxb) R.Br. leaves (Apocynaceae). An initial estimation of total phenolic and flavonoid content after met...

Effects of pre-treatment with the alcoholic extract of I. tinctoria (500 mg/kg body wt/day, p.o. for 21 days) on liver antioxidant defense system during acute hepatitis induced by D-galactosamine (D-GalN)/endotoxin (LPS extracted by phenol water method from E. coli serotype 0111.B4; 300 mg and 30 micrograms/kg body wt/day, i.p., 18 hr before the assay) were investigated on the activities of enz...

Purpose: Indigofera tinctoria Linn. of the Fabaceae family is claimed to be useful in the treatment of a variety of epileptic disorders in Indian traditional system of medicine. The present study was designed to verify this claim. Methods: Status epilepticus was induced in male albino rats of Wistar strain by administration of pilocarpine (30 mg/kg, i.p.) 24 h after injection of lithium chlorid...
