neutralization effects of acorus calamus and withania somnifera root extracts were tested against echis carinatus venom. both plant extracts were effectively neutralized the various pharmacological activities induced by echis carinatus venom. about 0.14 mg of acorus calamus and 0.16 mg of withania somnifera root extracts were able to completely neutralize the lethal activity of 2ld 50 of echis ...

Neutralization effects of Acorus calamus and Withania somnifera root extracts were tested against Echis carinatus venom. Both plant extracts were effectively neutralized the various pharmacological activities induced by Echis carinatus venom. About 0.14 mg of Acorus calamus and 0.16 mg of Withania somnifera root extracts were able to completely neutralize the lethal a...

In a study of human yawning Robert Provine (1986) remarked that yawning is a prominent stereotyped action pattem and releasing stimulus which “does not deserve its current status as a minor behavioural curiosity”. Indeed, “yawning may have the dubious distinction of being the least understood, common, human behaviour”. In contrast, a large body of experimental data has been collected during the...

Isothiocyanates (ITCs) are naturally occurring molecules belonging to highly reactive organosulphur synthons, with the general structure R–N=C=S. The precursor molecule glucosinolate anions are hydrolyzed enzymatically (under the effect of myrosinase enzymes) or unenzymatically to produce nitriles or isothiocyanates depending upon conditions such as pH and temperature. Brassicaceae  Family is k...

Quantum chemical (MNDo)caleulations have beenused toelucidate the molecular properties and structure - activity relationships of dihydropyridine (DHP) type calcium antagonists. There is a good corielation between the net atomic charges on various atoms of the 4 - phenyl ring of dihydropyridines and pharmacological activity. .Also, activity decreases with increasing free rotation of the phen...

Ginger is a medicinal plant that has been widely used in Chinese, Ayurvedic and Tibb-Unani herbal medicines all over the world and has a long history of use in traditional systems of medicine. The primary pungent agents are due to the presence of phenylalkylketones or vanillyl ketones. Gingerol and shogaol are two most active constituents of ginger based preparations. They are reported to demon...
