An Ulcer is a sore which means an open painful wound in mucous membranes or mucosal linings of the body. Gastro intestinal ulcers frequently occur in the stomach and duodenum where acid and pepsin activity is greatest. Peptic ulcer disease can be prevented by strengthening the cytoprotection, the defensive mechanism of gastric mucosa, rather than attenuating factor of aggression causing ulceration. Michelia champaca Linn., a well known member of Magnoliaceae is known for its fragrant flowers and various pharmacological actions. Anti-ulcerogenic activity of Michelia champaca Linn. flower and leaves are evaluated against aspirin induced gastric ulcers in pylorus ligated rats. The anti-ulcer potential is determined by using gastric juice volume, total acidity, pH and ulcer index. Both aqueous and alcoholic extracts of Michelia champaca Linn. flower and leaves are evaluated for their anti ulcer potential at about a dose of 300mg/kg b.wt, and are compared with the standard drug Cimetidine (50mg/kg b.wt). All the four extracts are said to possess significant anti ulcer potential by decrease in gastric juice...

The Methanolic extract of leaves (LE) and Methanolic extract of flowers (FE) of Nerium indicum (Arali) was analysed for Antioxidant activity (AOA) in terms of DPPH free radicals, Total Phenolic Content (TPC) was measured in terms of Gallic acid equivalent and Flavonoid content was analysed in terms of Quercetin equivalent. The antioxidant activities of (LE & FE) were found to be 72.8% and 67 %. TPC of study extracts (LE & FE) were found to be 227 mg/100g and 449 mg/100g. The Total Flavonoid content of (LE & FE) were found to be 125 mg/100g and 199 mg/100g respectively. Superoxide anion radical scavenging activity of flowers was 66 % compared to leaves 25 %. Similarly Lipid Peroxidation showed higher activity in flowers than leaves. Enzymatic antioxidant activity such as Superoxide Dismutase, Glutathione peroxidase and Catalase of Nerium indicum flowers were around 10% to 30% higher than that of leaves. The results clearly indicate that the methanol extracts of Nerium indicum flowers have more potent antioxidant activity than...

The convenience of administration and improved patient compliance are important in the design of nasal drug delivery system which remains the preferred route of drug delivery in spite of various disadvantages. Therapy through intranasal administration has been an accepted form of treatment in the Ayurvedic system of Indian Medicine. Advances in biotechnology have made available a large number of protein and peptide drug for the treatment of a variety of diseases. These drugs are unsuitable for oral administration because they are significantly degraded in the gastrointestinal tract or considerably metabolized by first pass effect in the liver. Even the parenteral route is inconvenient for long term therapy. Of many alternate routes tried, intranasal drug delivery is found much promising for administration of these drugs. In this article, an overview on the design and development of intranasal drug delivery system is presented. Advantages of NDDS are Drug degradation that is observed in the gastrointestinal tract is absent, hepatic first pass metabolism is absent, Rapid drug absorption and quick onset of...

The present study was designed to determine the antidiabetic activity of the methanol: ethyl acetate (1:9) extract of flower buds of Peltophorum pterocarpum on alloxen and glucose indueced diabetic mouse model. The extract was given intraperitonially at a dose of 200 mg/kg body weight and the hypoglycemic effects compared with metformin, a standard drug. The extract reduced blood glucose level in alloxan-induced diabetic mice by 60.40%, and 65.48% reduced by metformin at 12 hours in 24 hours treatment period. Preliminary phytochemical screening of the extract revealed the presence of different types of compounds including flavonoids and steroids. Our results suggest that Peltophorum pterocarpum has potential antidiabetic activity and may provide new molecules for the treatment of...

Cyclocondensation of α-bromo ketones with thiourea afforded 4-substituted 1, 3-thiazole-2-amines. These compounds on further treatment with α-bromo ketones afforded 3, 6-disubstituted imidazo[2, 1-b][1, 3]thiazole (1a-1j). All the synthesized compounds were confirmed for their structure by FTIR, 1H NMR and GSMS spectra and tested in vitro for their anti-microbial activity by cup plate method against Gram-positive bacterial strains (Bacillus subtillis, Staphylococcus aureus) Gram-negative bacterial strains (Pseudomonas aerugenosa, Kleibsella pneumonia) and fungal strains (Aspergillus niger, Candida albicans). The analogues 1b, 1h and 1i showed promising antimicrobial activity against gram-negative Kleibsella pneumonia; where as analogues 1b, 1e, 1g and 1h showed promising antifungal activity against Candida...
