Liposome-encapsulated fish oil protein-tagged gold nanoparticles for intra-articular therapy in osteoarthritis.

AIM: To provide multilayered combination therapies encompassing nanoparticles and organic peptides and to assess their efficacy in the treatment of arthritis. MATERIALS & METHODS: Fish oil protein (FP) was isolated from fish oil glands and tagged with spherical gold nanoparticles (GNPs). Tagged GNPs were encapsulated in DPPC liposomes (FP-GNP-DPPC) and characterized. RESULTS & CONCLUSION: FP increased the hydrophilicity of GNP, while encapsulation of FP-GNP within liposomes increased the hydrophobicity. In vitro release studies of FP-GNP-DPPC exhibited sustained release of FP in simulated synovial fluid. FP-GNP-DPPC injected into intra-articular joints of rats displayed anti-osteoarthritic effects in osteoarthritic rat model. This is the first study to report the anti-osteoarthritic activity of FP and DPPC encapsulated FP-GNP liposomes.

Factors influencing the place of delivery in rural Meghalaya, India: A qualitative study.

BACKGROUND: In Meghalaya, only 51.4% expectant mothers go for any institutional delivery with a wide rural-urban gap causing morbidity and mortality in the mothers and the neonates. OBJECTIVES: The objective of this study is to find out the factors influencing the choice of the place of delivery in rural women. METHODOLOGY: The present qualitative cross-sectional study was conducted from October to December 2016 in Bhoirymbong community health center (CHC) and the area catered to by it. This CHC was selected by purposive sampling. Data collection methods included focused group discussions and in-depth interviews. The data were analyzed manually using thematic content analysis. RESULTS: Most of the women in the study area opted for home delivery by traditional birth attendants (TBAs), on whose skills the community had strong faith. Financial constraints, fear of out-of-pocket expenditure, ignorance of available schemes, unavailability of transport, bad roads, and distant hospitals were found to be important causes of this choice. Home delivery apparently offered the women privacy and the opportunity to attend to their household chores and older children. Illiteracy, increasing age, and parity were risk factors for home delivery. Perceived need for institutional delivery was low. Staff attitudes and unnecessary referrals had an impact on the choice of place of delivery. CONCLUSION: In the rural areas of this study, home deliveries are the preferred norm. The wide range of factors identified in this study for the preference of TBA and home deliveries could help policy makers and program implementers to adopt socially and culturally appropriate community-based interventions that can contribute to the reduction of maternal, fetal, and neonatal mortality and morbidity and increase service utilization.

Anti-rheumatoid and anti-oxidant activity of homeopathic Guaiacum officinale in an animal model.

BACKGROUND: Homeopathy is a popular form of complementary and alternative medicine. Guaiacum extract is said to be useful for pain and inflammation, but there appears to be no scientific evidence to support this. AIMS: The aim of the present study was to evaluate the anti-rheumatic and anti-oxidant activity of homeopathic preparations of Guaiacum officinale (Gua) on experimental animal model. DESIGN: Rheumatoid arthritis (RA) was induced in male albino rats by Freund's complete adjuvant (FCA) at a dose of (0.25 mg heat killed Mycobacterium tuberculosis/ml of emulsion). Gua mother tincture (MT) (prepared from the latex part of the plant) (MT), Gua 30cc and 200cc were purchased commercially from King Company, Kolkata, India. Male albino Wistar rats (130 ± 10 g) were divided into 6 groups: Sham control; Arthritis control; Standard treatment indomethacin (0.25 mg 100 g(-1) p.o. × 5 alternative days), Gua MT (1 ml kg(-1) p.o. × 5 days) treated; Gua (30c 1 ml kg(-1) p.o. × 5 days) treated; Gua (200c; 1 ml kg(-1) p.o. × 5 days) treated. Anti-rheumatic activity was examined through physical, urinary, serum parameters. All the results were expressed in terms of mean ± SEM (statistical error of mean n = 6) at each dose level. The level of significance was determined through one-way analysis of variance (ANOVA), p < 0.05 was considered significant. RESULTS: It was observed that body weight, ankle and knee diameter, urinary parameters (hydroxyproline (OH-P), glucosamine, calcium (Ca(2)(+)), creatinine (CRE), phosphate (PO4(3)(-))), serum ACP (acid phosphatase)/ALP (alkaline phosphatase)/Ca(2+)/CRE/PO4(3-)/gamma-glutamyl transferase (GGT)/Lipid peroxidation (LPO)/Glutathione (GSH)/Superoxide dismutase (SOD)/Catalase, serum GGT, serum interleukins like IL-1ß/CINC-1/PGE2/TNF-α/IL-6, IL-12/IL-4/IL-6 levels were significantly affected. After treatment with Guaiacum in all 3 regimes was associated with normalization of these parameters compared to control group. CONCLUSION: These findings suggest that homeopathic G. officinale possesses anti-rheumatic and anti-oxidant activity in experimental animal and these activities may be more significant in higher potencies.
