Objective: Pittosporum angustifolium Lodd. is used to treat a variety of pathogenic diseases and inflamma-tion by Australian aborigines. Practitioners of complementary medicine frequently use herbal medicines concurrently with conventional antibiotics. There is a need to evaluate their effects in combination. Methods: The bacterial growth inhibitory activity of P. angustifolium leaf extracts was assessed against a panel of pathogenic triggers of some autoimmune diseases by standard disc diffusion and liquid dilution minimum inhibitory concentration (MIC) methods. Combinational effects between the extracts and con-ventional antimicrobials were classified using the sum of the fractional inhibitory concentration. Synergistic interactions were further assessed across a range of ratios by isobologram analysis. The tox-icity of the individual samples and combinations was evaluated by Anemia lethality and 3-(4,5-dimethyl thiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) human dermal fibroblast cell viability assays. Results: P. angustifolium leaf extracts strongly inhibited the growth of several bacterial triggers of autoim-mune diseases. The methanolic, aqueous and ethyl acetate extracts were pwrticularly good inhibitors of Proteus mirabilis and Klebsiella pneumonia growth (MIC=26 and 57 ng/mL respectively). Some combinations of the extracts and conventional antibiotics signiflcantlv potentiated the combined inhibitory activity compared to the individual components. Of the 250 combinations studied, approximately 0.02% showed synergistic interactions, 49.6% were additive, 46.8% showed indifferent interactions and antago-nism occurred in only 0.02% of the combinations. Interestingly, all of the synergistic and antagonistic combinations contained tetracycline as their antibiotic component. Conclusion: P. angustifolium leaf extracts inhibit the growth of pathogenic triggers of some autoimmune diseases. Some extracts also potentiated the activity of co

为丰富具有产吲哚-3-乙酸(IAA)功能的植物根际促生菌(PGPR),开发高效微生物菌肥,从南疆克孜勒苏柯尔克孜自治州耐盐植物盐爪爪根际土壤中分离产IAA的菌株。结合16S rDNA的限制性片段长度多态性PCR技术(PCR-RFLP)与16S rDNA序列分析进行菌种鉴定,分析高产IAA菌株对玉米和小麦种子发芽的影响,并通过盆栽试验验证其对盐碱胁迫下植株幼苗生长(株高、茎粗、地上干重等)的影响。结果表明,共筛选到67株PGPR菌株,其分泌IAA能力为16.65~71.63 mg·L^(-1),尤以PM14、PM18分泌量较高。PM14和PM18菌株同时兼具解磷、固氮能力。所有菌株分属6个菌属,以肠杆菌属占绝对优势。接种PM14和PM18均促进了玉米和小麦种子萌发,但菌液浓度高低对种子发芽的影响有显著差异(P<0.05)。接种处理增加了玉米株高、鲜重、地上干重、茎粗和根干重,分别增加了4.7%~37.2%、28.8%~94.5%、15.8%~157.9%、4.4%~35.5%和23.5%~82.4%,但叶绿素含量无显著变化。接种处理增加了小麦株高、茎粗、鲜重和地上干重,分别增加了9.5%~33.1%、13.0%~49.6%、57.4%~112.8%和71.4%~114.3%。除接种灭活的PM14导致小麦根干重与对照相比无显著差异,其他处理均有积极作用,提高了52.8%~69.0%,而所有处理对叶绿素含量均无显著影响。综上,本研究筛选的产IAA菌株提高了植株在盐碱胁迫下的抗性,对开发适用于盐碱地区的微生物菌肥有重要意义。

Over the past decade there has been a dramatic change in the treatment of patients with Crohn’s disease and ulcerative colitis, which comprise the inflammatory bowel diseases (IBD). This is due to the increasing use of immunosuppressives and in particular the biological agents, which are being used earlier in the course of disease, and for longer durations, as these therapies result in better clinical outcomes for patients. This, however, has the potential to increase the risk of opportunistic and serious infections in these patients, most of which are preventable. Much like the risk for potential malignancy resulting from the use of these therapies long-term, a balance needs to be struck between medication use to control the disease with minimization of the risk of an opportunistic infection. This outcome is achieved by the physician’s tailored use of justified therapies, and the patients’ education and actions to minimize infection risk. The purpose of this review is to explore the evidence and guidelines available to all physicians managing patients with IBD using immunomodulating agents and to aid in the prevention of opportunistic infections.
