NANOSUSPENSION: AN ATTEMPT TO ENHANCE BIOAVAILABILITY OF POORLY SOLUBLE DRUGS
Most of the new chemical entities coming out from High-throughput screening in drug discovery process are failing due to their poor solubility in the water. Poorly water-soluble drugs show many problems in formulating them in conventional dosage forms. One of the critical problems associated with poorly soluble drugs is too low bioavailability. The problem is even more complex for drugs belonging ...
TRANSGENIC ANIMALS: PRODUCTION AND APPLICATION
Organisms containing integrated sequences of cloned DNA (transgenes), transferred using techniques of genetic engineering (to include those of gene transfer and gene substitution) are called transgenic animals. The development of transgenic animals has been part of biotechnology research which has been expanding rapidly. Transgenic animals produced with the purpose of producing better and good qua...
A REVIEW ON ETHANOMEDICINAL USES AND PHYTO-PHARMACOLOGY OF ANTI-INFLAMMATORY HERB VITEX NEGUNDO

PHARMACOLOGICAL SCREENING OF ANTIULCER AGENTS: A REVIEW
Gastric hyperacidity and gastro duodenal ulcer is a very common global problem today. Among various causes of gastric ulceration lesions caused by stress, alcohol consumption, H.pylori infection and use of NSAIDs have been shown to be mediated largely through the generation of reactive oxygen species (ROS), especially hydroxyl radical (*OH). Hyper secretion of gastric acid is a pathological condit...

ANTI-ALLERGIC AND ANTICATALEPTIC ACTIVITY OF AQUEOUS EXTRACT OF LEAVES OF AILANTHUS EXCELSA ROXB.
The anti-allergic of an aqueous extract of the leaves of Ailanthus excelsa Roxb.(AELAq) was evaluated by using milk induced leucocytosis and eosinophilia in mice, passive paw anaphylaxis in rats models while the anticataleptic properties was evaluated by Clonidine induced catalepsy in mice mode. The extract significantly (*p<0.05, **p< 0.01) decreased the leucocytosis and eosinophilia along ...
MINOCYCLINE DECREASES ACETYLCHOLINESTRASE ACTIVITY IN INTRA-CEREBROVENTRICULAR STREPTOZOTOCIN INFUSED RATS
Alzheimer’s disease, a synonym for life threatening dementias is characterized by oxidative stress and neuroinflammation induced neuronal loss, impaired energy metabolism, and cholinergic deficit leading to severe cognitive impairments and other abnormal neuropsychiatric changes. Cholinergic hypothesis is the most accepted theory explaining pathology of AD and Acetylcholinestrase inhibitors are ...
