The results show that ·O - 2 can destroy structure and function of chloroplast, and cerium protects those of the cell organelle by cleaning ·O - 2 . The higher the concentration of cerium is, the stronger the protective effects of cerium is on chloroplast treated by ·O - 2 in the condition of the certain lower concentration of cerium. The function of cerium is as the same as SOD in scavenging ·O - 2 , and the effective time of protective effect is longer. This effect is more important as chloroplast is in photostage.展开更多
目的:利用16S r RNA基因测序技术,对慢性萎缩性胃炎的腻苔患者中舌苔的微生物优势菌群类型和含量进行分析。方法:采集慢性萎缩性胃炎49例腻苔患者的舌苔,对舌苔中微生物进行DNA提取后,采用Illumina Hi Seq测序方法对微生物的DNA测序。结...目的:利用16S r RNA基因测序技术,对慢性萎缩性胃炎的腻苔患者中舌苔的微生物优势菌群类型和含量进行分析。方法:采集慢性萎缩性胃炎49例腻苔患者的舌苔,对舌苔中微生物进行DNA提取后,采用Illumina Hi Seq测序方法对微生物的DNA测序。结果:获得慢性萎缩性胃炎的腻苔微生物的总片段为3 014 144,平均片段为70 357±8 960,有效片段为62 083±7 906,OTUs数目为1 472±384;在慢性萎缩性胃炎中,微生物在门水平上的优势菌群是分别是厚壁菌门、变形菌门、拟杆菌门、梭杆菌门、放线菌门等。结论:通过16S r RNA基因测序技术可以获得慢性胃炎腻苔的微生物组成,这种微生物的组成可能与疾病的发生、发展密切相关。展开更多
