The Antioxidant Polysaccharide from Semiaquilegia adoxoides (DC.) Makino Adjusts the Immune Response of Mice Infected by Bacteria. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:2719483.

Abstract
Semiaquilegia adoxoides (DC.) Makino is a herbal medicine and it is recorded that its water extract can be used to treat acute diseases caused by bacterial infections. In order to understand the polysaccharide of Semiaquilegia adoxoides (DC.) Makino (SMP), FT-IR and HPLC methods were performed to determine the basic chemical structure and monosaccharide compositions of SMP. The antioxidant capacity of SMP was analyzed by monitoring both the scavenging rate of DPPH and ABTS free radical. To investigate the effects of SMP on the acute bacterial disease, minimum inhibitory concentrations (MICs) of SMP on E. coli or S. aureus were detected; meanwhile, mice were administrated with SMP for 7 days and then infected with E. coli or S. aureus, and the parameters were measured at the 9th day. Results showed that SMP was a furanose which was mainly composed of glucose (60.3%) and had certain antioxidant activities. Both MIC values of SMP on E. coli and S. aureus were 250 ml/mL, which means that SMP has no direct antibacterial effects. The mice experiments revealed that SMP had potential effects on immunomodulatory by reducing WBC and the expression of serum IL-1, IL-6, and TNF-α and increasing IgM of E. coli or S. aureus infected mice. These findings supported the effect of Semiaquilegia adoxoides (DC.) Makino in folk use with scientific evidence.

Effects of a natural multi-component compound formulation on the growth, morphology and extracellular matrix production of human adult dermal fibroblasts. Exp Ther Med 2019; 18:2639-2647. [PMID: 31572512 PMCID: PMC6755435 DOI: 10.3892/etm.2019.7872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Accepted: 07/16/2019] [Indexed: 12/05/2022] Open
Abstract
The extracellular matrix (ECM) creates a tissue microenvironment able to regulate cellular signaling. The loss of ECM plasticity is associated with several pathologies, especially those involving chronic inflammation, therefore, the ECM represents a potential therapeutic target for certain conditions. The present study investigated the effects of a natural multi-component compound formulation, Galium-Heel®, on the growth, morphology and ECM production of human dermal fibroblasts (HDF). The effects of the formulation on HDF growth and morphology were assessed by sulforhodamine B assay, trypan blue exclusion staining, FACS and ultrastructural analyses. The effect of the compound on reactive oxygen species production by HDF was performed by dichlorofluorescin diacetate assay. The expression of ECM components, matrix metalloproteinases (MMPs) and signaling molecules was analyzed by western blot analysis. The present results demonstrated that Galium-Heel® did not significantly affect HDF growth, survival, cell cycle or morphology indicating the biocompatibility of the formulation. The formulation demonstrated antioxidant activity. Galium-Heel® was able to modulate ECM by regulating collagens (type I and III) and MMPs-3 and −7 expression. In addition, the formulation was able to regulate molecules involved in TGF-β signalling, including mitogen activated kinase-like protein, GLI family zinc finger 2 and pro-survival proteins such as AKT. The present results demonstrating the effects of a natural multi-component compound on ECM composition, highlighted the possibility of pharmacologically modulating ECM molecules. The recovery and the maintenance of ECM homeostasis might be considered as a potential therapeutic goal to ameliorate pathological conditions.
