Dillenia indica L. commonly known as elephant apple is distributed in the sub-Himalayan tract of India. The fruits of D. indica collected from Bhalukpong area of Sonitpur district of Assam (India) were dried, milled and extracted sequentially by Accelerated Solvent Extractor using four different solvents with increasing polarity (hexane < ethyl acetate < methanol < 50% aqueous methanol). Qualitative phytochemical analysis was carried out according to standard procedures. Total phenolic content (TPC) of all the extracts were determined by Folin-Ciocalteu’s method using UV-Vis spectrophotometer. Free radical scavenging activity were determined by measuring the decrease in the visible absorbance of 2,2-diphenyl-1-picrylhydrazyl (DPPH) on addition of the plant extracts and the mean inhibitory concentration (IC50) values were determined by plotting nonlinear regression curve. L-Ascorbic acid and gallic acid were used as standard in DPPH assay and TPC respectively. Phytochemical analysis confirms the presence of phenolic compounds in methanolic extract. The highest phenolic content (59.99±2.21 mg/g) was recorded in 50 % aqueous methanolic extract which also shows highest antioxidant activity with IC50...

Antimicrobial activity of compound (2) was investigated against pathogenic microorganisms: Staphylococcus aureus (Gram (+), Escherichia coli (Gram (-) and fungal strain, Candida albicans using the Well Diffusion and the Poison plate methods. Compound (2) was shown to inhibit pathogenic growth, and judging from the area of the zone of inhibition, the susceptibility of the microorganism against compound (2) follows the sequence: Staphylococcus aureus > Candida albicans > Escherichia coli. The area of zone of inhibition ranging from (4.64 mm2 to 6.47 mm2) and (4.64mm2 to 5.72 mm2) for the Well Diffusion and Poison plates respectively. Both methods indicate that the area of the zone of inhibition for compound (2) is more potent than reference antibiotics: Nystatin and...

Background: Enzyme catalysis is intermediate between homogeneous and heterogeneous catalysis. In general, it is similar to inorganic heterogeneous catalysis and sometimes it is called micro heterogeneous catalysis. Efficient enzyme catalysis depends on high specific nature of enzyme, pH, temperature, optimum temperature, colloidal nature, activator or co-enzyme, inhibitors or poisons. Immobilized β-galatosidase show high activity towards both pure lactose and lactose in skim milk, and a better thermal stability also. Methods: This study was done in CDRI, Lucknow. In this study β-galatosidase was extracted by Kluyveromyces lactis and enzyme assay done by GOD/POD method. Partial purification of enzyme was done by precipitation with ammonium sulphate, DEAE-cellulose column chromatography followed by SDS-PAGE. Immobilization of K. lactis cells was done by Entrapment method in which we agarose beads, plyacrylamide beads and alginate beads were used to analyze the catalytic activity of β-galatosidase on different parameters. Results: In this study the effect of temperature, pH, and amino acids on normal β-galatosidase and on immobilized β-galatosidase were analyzed. Immobilized enzyme showed the decreasing conversion level...

This study was undertaken to determine the prevalence and determinants of family self-medication in children in northeast India. A validated structured interview schedule was used in 487 caregivers of children attending the out-patient department and in-patient ward of the department of pediatrics, Regional Institute of Medical Sciences, Imphal, India. The study schedule included questions related to the socio-demographic profile of the participants and their practice of self-medication for their children for the last 6 months. Descriptive statistics like mean and percentage were used. Chi square test was used for significance. A p value of <0.05 was considered as significant. The prevalence of self-medication was found to be 56.1%. The preference of self-medication was significantly dependent on the age of children. The preference was, however, not significantly dependent on gender, birth order of children, or educational and socio-economic status of...

Inflammatory diseases including different types of rheumatic diseases are a major and worldwide problem. Now a day’s, world population moves towards herbal remedies for treatment. Several edible plants parts are used in traditional medicine for the treatment of inflammatory conditions. Amomum subulatum Roxb (Zingiberaceae), commonly known as large cardamom, is traditionally used for several medicinal purpose in India. The present study assessed anti-inflammatory activity of its fruits extracts (methanolic and aqueous) at a dose of 250 mg/kg and 500 mg/kg against carrageenan induced paw edema in rats. Both the extracts were able to show a dose dependent anti-inflammatory activity with compared to ibuprofen as a...
