Yet, over the past 10-15 years, a plethora of international researchers have established that individual and comprehensive lifestyle changes can prevent and potentially improve ED. We review the lifestyle evidence that should equate to grade A or level 1 evidence recommendations for ED. We also review the evidence for Panaxginseng, an over-the-counter （OTC） dietary supplement with a 35-year history of laboratory investigations, multiple positive randomized trials over approximately 15 years and several independent meta-analyses and systematic reviews. Perhaps it is time to at least discuss and even emphasize lifestyle and other non-conventional interventions in ED guidelines so that patients can explore a diversity of potentially synergistic choices with their physicians and can improve their quality and quantity of life. Ignoring the consistent, positive data on lifestyle modifications in ED guidelines, for example, is tantamount to ignoring diet and lifestyle changes to reduce the risk of or ameliorate cardiovascular diseases.展开更多
目的:筛选对人参黑斑菌、人参锈腐菌等人参致病菌有较好抑菌活性的微生物菌株,为人参病害生防防治提供参考依据。方法:采用平板稀释法从人参栽培土壤和菌剂产品中分离菌株;以人参致病菌为靶标,采用对峙培养法筛选拮抗菌;分别采用16S r ...目的:筛选对人参黑斑菌、人参锈腐菌等人参致病菌有较好抑菌活性的微生物菌株,为人参病害生防防治提供参考依据。方法:采用平板稀释法从人参栽培土壤和菌剂产品中分离菌株;以人参致病菌为靶标,采用对峙培养法筛选拮抗菌;分别采用16S r DNA和28S r DNA序列分析方法鉴定细菌和真菌菌株的分类学地位。结果:共计从人参栽培土壤中分离到66株菌,其中菌株X对人参致病菌表现较好抑菌活性;从商品化菌剂中分离出17株菌,其中菌株QM、BM2、HZ3、GG、HC和DD对人参致病菌表现较好抑菌活性。经鉴定,菌株X为解淀粉芽孢杆菌(Bacillus amyloliquefaciens),QM、BM2和HZ3为甲基营养型芽孢杆菌(B.methylotrophicus),GG为枯草芽孢杆菌(B.subtilis),HC为棘孢木霉(Trichoderma asperellum),DD为平展木霉(T.effusum)。结论:筛选出的7株拮抗菌对多种人参致病菌有较好抑菌活性,菌株X可用于生防菌剂开发,与菌株QM、BM2、HZ3、GG、HC和DD对应的商品化菌剂可用于人参病害防治。展开更多
