Dillenia indica linn fruit, commonly known as elephant apple has indigenous use in various culinary dishes of Assam and it has a history of being used as traditional medicine. The present study was undertaken to evaluate its antioxidant and chemopreventive properties. Ethanolic extract of Dillenia indica fruit was used as experimental sample. Antioxidant activity was studied in vitro, at concentrations (20µg/ml, 40µg/ml ,60µg/ml, 80µg/ml, 100µg/ml) where it showed significant (p<0.05) inhibition of free radicals formation, hydroxyl radical and nitric oxide scavenging property and also reducing ability when compared with a standard antioxidant, ascorbic acid. Chemopreventive potential was evaluated in 8-10 weeks old swiss albino mice by giving a single tropical application of initiator- 7,12-dimethylbenza(α)anthracene (DMBA) at a concentration of 100µg/100µl acetone and promotion after 14 days by repeated application of croton oil (1% in acetone) thrice a week for 15 weeks. Oral application of D.indica at dose of 250 mg/kg body weight of mice selected after acute oral toxicity test, showed significant (p<0.05) reduction in DMBA induced mice skin...

Flavonoids are the natural compound widely distributed in plant kingdom, it is responsible for the various colors exhibited by bark, leaves, flowers, fruits and seeds of plants. They are the secondary metabolites of plant with significant antioxidant properties. Flavonoids have antioxidant, sedative, antidepressant, anticonvulsant, anti-proliferative, anti-inflammatory, anti-microbial, anticancer, cardioprotective, antihypertensive, antiulcerogenic, antidiabetic and hepatoprotective activity. Many researchers have revealed that the above mentioned pharmacological actions are mainly due to its antioxidant property. Flavonoids have effect on mammalian enzymes like protein kinases, alpha-glucosidase and aldose reductase, thereby regulate multiple cellular signaling pathway that were altered during disease conditions. Various researches on flavonoids are in progress due to its versatile health benefits. En number of flavonoids are available in the market as pharmaceutical products because of its cost effective bulk production and health benefits. The present review is focused on the classification, metabolism, pharmacological and biological actions and flavonoid supplement available in...

Bromhexine hydrochloride, mucolytic agent used in the treatment of respiratory disorders. Azithromycin is use in wide variety of bacterial infections. The aim of this present work is to formulate dual drug delivery system containing azithromycin as immediate release and bromhexine hydrochloride as sustained release action. The sustained release part as core tablet of bromhexine prepared because of the frequent daily dosing is required for therapy. The floating formulation of core tablet was prepared because it dissolved in the pH range of 1 to 4. The core tablets of bromhexine hydrochloride were prepared by wet granulation technique. The prepared core tablets were evaluated for different parameters for selection of formula for floating the tablets. The core compressed tablets were evaluated for quick release of coat layer containing disintegrants. The various formulations of core tablets were prepared using HPMC K4M and K15M in different concentration. The prepared tablets were evaluated for physical parameters, disintegration time, floating lag time and drug release study. All the batches show around 70 sec disintegration time,...

Asthma is obAdd Newstructive disease characterized by bronchoconstriction and inflammation for which beta 2 (β2) agonists that act through the β2 adrenoceptor are the first line agents of choice. Glycine16Arginine (Gly16Arg) is a common single nucleotide polymorphism (SNP) of β2 adrenoceptor whose effects on treatment response remain inconclusive. Hence the study aims to understand and determine the effect of the Gly16Arg SNP on β2-agonist binding and treatment responsiveness. Structure guided mutagenesis was performed with discovery studio tool, energy minimization was performed using Chemistry at Harvard Macromolecular Mechanics(CHARMM) force field, protein confirmation was studied using Ramachandran plot, Molecular docking analysis was performed using Autodock 4.2 and statistical analysis was performed using Graph pad prism 6.0. Statistically significant difference was observed between the binding energies of Glycine16 (Gly16) and Arginine16 (Arg16) groups. Further, the binding energies of β2 agonists were found to be comparatively less in Arg16 group than the Gly16 group suggesting that the Arg16 variant carriers may be poor responders of β2 – sympathomimetic therapy. Presence of functional non...

Man has been dependent on plants for the treatment and cure of different diseases since time immemorial. Plants have served not only as a source of food and shelter but also as a very important source of different “portions” used for the treatment and cure of diseases. These portions are herbal or plant based mixtures made by traditional healers; who are individuals having a knowledge of medicinal plants of that particular area. In India, there are several thousands of medicinal plants, known to be used for specific diseases. Canavalia virosa is one such plant, known to be used for different curative purposes. However, it is more popular as a food plant as it is a tribal pulse. Canavalia virosa is a flowering plant belonging to the family Fabaceae. It is one of the lesser know vines from the genus Canavalia. It is not only important as an alternative protein source but also a promising medicinal plant as indicated by traditional medicine systems. This paper brings together some of the...
