Himalayan honey loaded iron oxide nanoparticles: synthesis, characterization and study of antioxidant and antimicrobial activities.

Background: Himalayan honey, a natural product of wild honey bees found in the Himalayan mountains of Nepal, has been used in medicine for many years. The successful development of nanotechnology and beneficial effects of honey would bring a new opportunity to synthesize hybrid nanomaterials for biomedical applications. Thus, the purpose of this study was to load Himalayan honey onto iron oxide nanoparticles (IO-NPs) and study their antioxidant and antimicrobial activities. Methods: Himalayan honey loaded iron oxide nanoparticles (HHLIO-NPs) were synthesized and X-ray diffraction (XRD) and scanning electron microscope (SEM) analyses were performed for characterization. UV-VIS spectra confirmed the loading of honey onto nanoparticles. The antioxidant activity of these nanoparticles was studied against 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical system. We also tested antimicrobial activity of HHLIO-NPs using well diffusion method towards both Gram-positive and Gram-negative bacterial strains of Staphylococus aureus & Escherichia coli. Results: From XRD analysis, the average particle size was found to be 33-40 nm. The SEM images show needle shape porous structures of HHLIO-NPs compared to free IO-NPs indicating the surfactant-like behaviour of honey. In DPPH radical system, the scavenging activities of Himalayan honey (HH), free IO-NPs and HHLIO-NPs ranged 7.93-35.99%, 11.02-52.02% and 16.10-80.52% respectively, with corresponding IC50 values of 1.36 mg/mL, 1.09 mg/mL and 0.52 mg/mL. The antimicrobial property of all test samples showed a noteworthy inhibition on both bacterial strains. However, the HH and HHLIO-NPs exhibited strong antibacterial activity against E. coli. Conclusion: This work reveals that the biological activity of HH is enhanced significantly after loading into IO-NPs. Thus, the HHLIO-NPs would be a promising alternative for antioxidant and antimicrobial agents.

A new experimental community pharmacy internship module for undergraduate pharmacy students in western Nepal: overview and reflections.

Community pharmacies in Nepal and other South Asian countries are in a mediocre state due to poor regulation and the fact that many pharmacies are run by people with insufficient training in dispensing. This has led to the inappropriate use of medicines. The problems due to poor regulation and the mediocre state of community pharmacies in South Asia encompass both academia and clinical practice. In this paper, a 2-week community pharmacy internship programme completed by 2 graduating pharmacy students of Pokhara University (a Nepalese public university) at Sankalpa Pharmacy, Pokhara, Nepal is illustrated. During the internship, they were systematically trained on store management, pharmaceutical care, counselling skills, the use of medical devices, pharmaceutical business plans, medicine information sources, and adverse drug reaction reporting. An orientation, observations and hands-on training, case presentation, discussion, and feedback from 2 senior pharmacists were used as the training method. A proper community pharmacy internship format, good pharmacy practice standards, and a better work environment for pharmacists may improve the quality of community pharmacies.
