DC.(AL)is extensively used in Chinese,Thai,and Japanese traditional medicines as crude extracts/decoctions or a component in various herbal formulations.Various pharmacological activities of Al.and its major constituents have been demonstrated in ritro.ex ciro.and in animal models.Results from the toxicity studies in animal models suggest safety profile of AL,and its active constituents.Despite extensive use with positive impression in many diseases,there has not been a clinical study that can conclusively support its efficacy and safely profile in human.This review comprehensively summarizes current information on the pharmacological activities of AL and their active constituents including anticancer,anti-inflammatory,antimicrobial and antipyretic activities,as well as activities on central nervous,cardiovascular,and gastrointestinal systems.展开更多

In the present study, we determined the effects of polysaccharides extracts from these two herbs on IEC-6 cell migration and explored the potential underlying mechanisms. A migration model with IEC-6 cells was induced using a single-edged razor blade along the diameter of cell layers in six-well polystyrene plates. The cells were grown in control--media or media containing spermidine(5 μmol·L^(-1), SPD), alpha-difluoromethylornithine(2.5 mmol·L^(-1), DFMO), 4-Aminopyridine-(40 μ-mol·L^(-1), 4-AP), the polysaccharide extracts of RA or RAM(50, 100, or 200 mg·L^(-1)), DFMO plus SPD, or DFMO plus polysaccharide extracts of RA or RAM for 12 or 24 h. Next, cytosolic free Ca^(2+)([Ca^(2+)]cyt) was measured using laser confocal microscopy, and cellular polyamine content was quantified with HPLC. Kv1.1 mRNA expression was assessed using RT-qPCR and Kv1.1 and RhoA protein expressions were measured with Western blotting analysis. A cell migration assay was carried out using Image-Pro Plus software. In addition, GC-MS was introduced to analyze the monosaccharide composition of both polysaccharide extracts. The resutls showed that treatment with polysaccharide extracts of RA or RAM significantly increased cellular polyamine content, elevated [Ca^(2+)]cyt and accelerated migration of IEC-6 cells, compared with the controls(P < 0.01). Polysaccharide extracts not only reversed the inhibitory effects of DFMO on cellular polyamine content and [Ca^(2+)]cyt, but also restored IEC-6 cell migration to control level(P < 0.01 or < 0.05). Kv1.1 mRNA and protein expressions were increased(P < 0.05) after polysaccharide extract treatment in polyamine-deficient IEC-6 cells and RhoA protein expression was increased. Molar ratios of D-ribose, D-arabinose, L-rhamnose, D-mannose, D-glucose, and D-galactose was 1.0:14.1:0.3:19.9:181.3:6.3 in RA and 1.0:4.3:0.1:5.7:2.8:2.2 in 展开更多
