    In ovo antiviral activity of Synadenium glaucescens (pax) crude extracts on Newcastle disease virus
    (2013-04-10) Mabiki, F.P; Mdegela, R. H.; Mosha, R.D; Magadula, J.J
    Investigation on the effect of root bark and wood, stem bark and wood, leaves and sap of Synadenium glaucescens extracts against Newcastle disease (ND) virus was done using an in ovo assay. Viable 9 days embryonated chicken eggs were arranged into 25 treatment groups (n = 5). Groups 1 to 21 were challenged with a 13C/SUA virulent strain of ND virus treated with extract at concentration of 0.2 mg/ml. Un-inoculated group saved as negative control and groups inoculated with virus and diluent saved as positive controls. Haemagglutination test was used to quantify the amount for ND virus units. Embryo survival and embryo weight were significantly higher (P ≤ 0.05) in groups treated with S. glaucescens extracts than the positive control. The root bark demonstrated significantly higher antiviral activities (P ≤ 0.05). Furthermore, treatments with ethanolic extract SE1 resulted into 100% embryo survival, 91.2% mean embryo weight and reduced viral load by 99.2%. The minimum dose of SE1 with the highest efficacy was 0.2 mg/ml. The percent mean embryo weight and haemagglutination test demonstrated negative correlation (R2 = 0.94). These findings validate the ethnoveterinary potential of S. glaucescens and the feasibility of its use for treatment and control of ND.

    Trade development of medicinal plants products in Tanzania: an overlooked research area?
    (TAJAS, 2022) Mpelangwa, E.M; Makindara, J.R; Sorensen, O.J; Bengesi, K.M.K; Mabiki, F.P
    The existence of trade of products of medicinal plants reflects their significance on health care and the local economy. Consumption trends have shifted medicinal plants from local consumptions to economic contexts. However, the engagement of medicinal plants products within the market economy necessitates the understanding of the trade system and management for economy, health and biodiversity securities. This paper used a systematic literature review to assess information on trade of medicinal plants in order to explore its structure and identify research gaps. About 377 research articles were identified where 46 of them were reviewed. The literature indicate the contexts of the trade are natural forests and health sectors which influence supply and demand sides, respectively. The supply chain differ among literatures. The results indicate that, despite the importance of the medicinal plant trade in Tanzania, its understanding rely on isolated bits and pieces of information from other research articles, the evidence of an overlooked research area. The identified research gap was lack of information on the trade like value chain and trade mechanisms. The study recommends further research to combine ethnomedicine, conservation and economics research domains which can ensure sustainable use of scarce resources of medicinal plants to meet the limitless demand of the healthy community.
