The current study was aimed at evaluating the antihyperalgesic effects of lignans (phyllanthin and hypophyllanthin) and tannin (corilagin) rich three standardized extracts of Phyllanthus amarus in a model of chronic musculoskeletal inflammatory pain. Three percent carrageenan injected in the gastrocnemius muscle produced hyperalgesia to mechanical and heat stimuli ipsilaterally, which spreads to the contralateral side within 7 to 9 days. ⋯ In conclusion, we strongly suggest that the observed antihyperalgesic and antiinflammatory effects of P. amarus in current pain model are mediated via spinal or supraspinal neuronal mechanisms, mainly by inhibition of PGE2. Modulation of chronic muscular inflammation may be due to presence of phytoconstituents like phyllanthin, hypophyllanthin, and corilagin, which offers a promising means for treatment of chronic muscle pain.

Randomized Controlled Trial
Effect of Silymarin Administration on Cisplatin Nephrotoxicity: Report from A Pilot, Randomized, Double-Blinded, Placebo-Controlled Clinical Trial.
Despite several introduced preventive modalities, cisplatin nephrotoxicity remains a clinical problem. Some in vitro and in vivo studies have addressed the protective effects of silymarin against cisplatin nephrotoxicity. This study evaluated the effects of silymarin administration on cisplatin nephrotoxicity as the first human study. ⋯ Incidence of AKI and the magnitude of urinary magnesium and potassium wasting did not differ between silymarin and placebo groups. No adverse reaction was reported by silymarin administration. Prophylactic administration of conventional form of silymarin tablets could not prevent cisplatin-induced urine electrolyte wasting or renal function impairment.

In the absence of any known therapeutically useful drug or vaccine available to combat Ebola, the disease has emerged as one of the most globally important crisis of the year. In the affected West African regions, no one seems to know what drug to use or even try on Ebola patients, while in the West, the debate on discovering new drugs versus repurposing old ones is heating up. Because Ebola affected countries are highly reliant on traditional medicines, we herewith suggest recording plants used by Ebola survivors as they may serve as sources of novel therapeutic agents in the future.

Review Meta Analysis
Dang shen [Codonopsis pilosula (Franch.) Nannf] herbal formulae for chronic obstructive pulmonary disease: a systematic review and meta-analysis.
This systematic review and meta-analysis assessed the efficacy and safety of Dang shen [Codonopsis pilosula (Franch.) Nannf., root] formulae for the treatment of chronic obstructive pulmonary disease (COPD). English and Chinese databases were searched, and 48 randomized controlled trials were included. Dang shen formulae improved lung function forced expiratory volume in 1 s compared with conventional pharmacotherapy (CP) [mean difference (MD) 0.22 L, 95% confidence interval (CI) 0.13-0.31, p < 0.001, I(2) = 5%] and quality of life (St. ⋯ Dang shen formulae appear to improve some aspects of the included COPD outcomes. However, owing to methodological flaws, the current evidence is inadequate to support the routine use of Dang shen formulae outside of Chinese medicine practice. However, these results justify further investigation.

Saponins are a diverse group of biologically functional products in plants. Soyasaponins are usually glycosylated, which give rise to a wide diversity of structures and functions. In this study, we investigated the effects and molecular mechanism of soyasaponins Aa and Ab in regulating adipocyte differentiation and expression of adipogenic marker genes in 3T3-L1 adipocytes. ⋯ In addition, soyasaponins Aa and Ab suppressed the transcriptional activity of peroxisome proliferator-activated receptor γ (PPARγ) in HEK 293T cells. Furthermore, we confirmed that the expression of PPARγ and of CCAAT-enhancer-binding protein α (C/EBPα) was suppressed at both the mRNA and protein levels in 3T3-L1 adipocytes by treatment with soyasaponins Aa and Ab. Taken together, these findings indicate that soyasaponin Aa and Ab markedly inhibit adipocyte differentiation and expression of various adipogenic marker genes through the downregulation of the adipogenesis-related transcription factors PPARγ and C/EBPα in 3T3-L1 adipocytes.
