Aim: The aim of the study was to employ cumin oil in the synthesis of silver nanoparticles and check the antioxidant activity of the cumin oil mediated silver nanoparticles. Background: The introduction of Nanoparticles (NPs) has revolutionized every field including medicine, nutrition and energy. The use of nanotechnology in medicine especially for drug delivery is shown to have various benefits. Nanoparticles are being used to reduce toxicity and side effects that drugs may impose to the patient. Cumin (Cuminum cyminum) is a common spice used for its distinct aromatic effect. Plant mediated biological synthesis of nanoparticles has been gaining importance due to its simplicity and eco friendliness. This study therefore was aimed to synthesize cumin oil mediated silver nanoparticles and assess its antioxidant activity. Materials and Methods: Cumin oil mediated silver nanoparticles were initially synthesised and characterised by UV-Visible spectrophotometer and TEM. Further the cumin oil mediated AgNPs were subjected to DPPH assay to determine the antioxidant activity. Results: Cumin oil mediated AgNPs were biosynthesised with ease and showed good antioxidant activity compared to standard. Conclusion: This study conclude that cumin seed oil mediated silver nanoparticles have the potential to be used as an effective antioxidant. Hence, it may be employed in large scale production and may be used in many medicinal applications where there is a need for antioxidant.

Background: Lutein is a carotenoids vitamin rich in many fruits and vegetables and also available in multivitamin products. It is consumed for its effect on eye disease, cancer, diabetes and other health conditions. Recently, herbal preparations are increasingly used in healthcare systems and concomitant administration of synthetic medications may cause pharmacokinetic or pharmacodynamic interactions leading to very serious medical problems. Understanding the ability of herbal extracts and preparations to modulate the metabolizing enzymes can help the health system for proper treatment of patients and thereby can avoid many adverse effects associated with it. The aim of the study was to find the effect of lutein isolated from Tagetes erecta L on cytochrome P450 isoform CYP3A4. Materials and Methods: The different concentrations of lutein (5 \– 100\μg/ml), potassium phosphate buffer, CYP450 reagent and substrate 7-Benzyloxy-4-trifluoromethylcoumarin (BFC) were added to a 96-well plate. The fluorescent intensities of the products were measured by Perkin Elmer Enspire fluorescence reader using an excitation and emission wavelength of 405 nm and 460 nm, respectively to examine the effect of lutein on Cytochrome P 450 isoform CYP3A4 and the IC50 was calculated by plotting concentrations of lutein against the corresponding percent inhibition. Results: All the tested concentrations of lutein showed potent inhibition against CYP3A4 in a dose \– dependent manner. The IC50 value was found to be 35.27\μg/ml. Conclusion: The inhibitory effect of lutein indicates the possibilities of herb-drug interaction if it is co \– administered with prescribed drugs that are normally metabolised by CYP3A4 enzyme.

Background: Advanced glycation end products(AGEs) are formed by non-enzymatic glycation of proteins that enhance vascular permeability in both micro and macro vascular structures by binding to specific macrophage receptors. AGEs affect nearly every type of cells and molecule in the body and play causative role in the vascular complication in diabetes mellitus. Materials and Method: AGE reaction solution was constituted with 10mg/ml bovine serum albumin in 50mM sodium phosphate buffer (pH 7.4) and 0.02\% sodium benzoate into 0.2M fructose and 0.2M of glucose. 2.5 ml of the reaction mixture was treated with lutein (10, 20, 40, 60, 60, 80, 100, 120, 140 \μ g/ml in methanol). Amino guanidine was used as the positive control. After incubating at 37\°C for 7 days, the fluorescence intensity of the reaction was determined at excitation and emission wavelength of 350 nm and 450 nm, respectively, using a multimode reader. The percentage activity was calculated with respect to solvent control. Result: 7 days of exposure to lutein showed a maximum inhibition of 89.27\±0.24 \% at 140\μg/ml and Amino guanidine exhibited 90\% of inhibition. The IC50 of Lutein for AGE inhibition was found to be 77.78\μg/ml and for AG, 72.66\μg/ml.Conclusion: The non-enzymatic adduct formation between the keto group of sugar and amino group of proteins is one of the molecular basis of diabetic complications in hyperglycaemic state. Inhibition of this process will be useful in the management of diabetic complications. Lutein showed dose dependent inhibitory effect on the protein glycation.Hence, it may be used for the management of diabetic complication.

Aim: To determine the prevalence of complementary and alternative medicine among pharmacists. Materials and method: This survey was a cross sectional study. A set of 30 questionnaires containing 15 questions where given to various pharmacists of different colleges. Datas were collected and statistics was done using SPSS software and represented in graph form. Background: Use of complementary and alternative medicine (CAM) by the U.S. population increased significantly in the past 2 decades. The purpose of this study was to determine, among the Indian community, the prevalence and utilisation patterns of complementary and alternative medicine (CAM), attitudes associated with CAM use and communication patterns of CAM users. Conclusion: The knowledge about and use of CAM is wide among pharmacists . In- depth studies on the knowledge and use of CAM among other health care professionals and among ethnic minorities are urgently needed and may help to better manage the treatment of minor disorders as well as chronic diseases.
