The pot experiment results showed that inoculation with A1501 and A1513 could promote the growth and grain yield of rice. Comparison with the non\|inoculation, the grain yeild of rice treated with A1501 and A1513 increased by 8 5% and 10 3% respectively. And %Ndfa of rice shoot and grain estimated by 15 N\|isotope dilution method was 9 00% and 11 5%, respectively, which was consistent with the increment of the total N(8 5% and 11 6%,respectively).

盆栽结果表明，接种A.faecalis 显著提高了水稻的生长，接种A1501 和A1513 的水稻稻谷产量分别比未接种提高了85％和103％，用15N 同位素稀释法估测水稻地上部总氮中来源联合固氮的百分率达900％和115％，其结果与水稻地上部总氮量的增加幅度（86％和116％）基本一致。

Methods The present study included twelve undialyzed ESRD patients with anemia.The sera from the uremic patients were added to CFU-E and BFU-E culture in the concentrations ranging from 1.25% to 5%.In vitro CFU-E and BFU-E growth in the presence of sera from ESRD patients was compared with in the presence normal human subjects with the use of normal mice bone marrows.

选择12例尿毒症肾性贫血未透析患者为试验组，另选正常健康体检者12例为正常对照组，将实验组、正常对照组血清分别稀释成不同终浓度，采用甲基纤维素细胞培养的方法对小鼠骨髓细胞进行培养，对比不同浓度血清组红系集落形成单位、红系爆式形成单位的集落数。

objective to investigate the existence of the erythropoiesis inhibitors.methods the present study included twelve undialyzed esrd patients with anemia.the sera from the uremic patients were added to cfu-e and bfu-e culture in the concentrations ranging from 1.25% to 5%.in vitro cfu-e and bfu-e growth in the presence of sera from esrd patients was compared with in the presence normal human subjects with the use of normal mice bone marrows.results the effects of the sera from uremic patients on cfu-e and bfu-e colony growth in concentrations ranging from 1.25% to 5% were investigated to be dose-dependent.the effect increased with the concentrations increasing of the sera（p＜0.05）.there were not significant inhibitory effect on the cfu-e and bfu-e growth of mice bone marrow in vitro from sera of the normal subjects.conclusion the erythropoiesis inhibitors exist in uremic sera which has a dose-dependent inhibitive effects on the growth cfu-e and bfu-e of normal mice bone marrow cells.

选择12例尿毒症肾性贫血未透析患者为试验组，另选正常健康体检者12例为正常对照组，将实验组、正常对照组血清分别稀释成不同终浓度，采用甲基纤维素细胞培养的方法对小鼠骨髓细胞进行培养，对比不同浓度血清组红系集落形成单位、红系爆式形成单位的集落数。结果在实验组中，与血清浓度为0的浓度组相比，与各浓度组血清共同培养的小鼠骨髓cfu-e和bfu-e的集落数均明显减少，且随血清浓度的增加，小鼠骨髓cfu-e和bfu-e的集落数逐渐减少，各浓度组间差异有显著性（p＜0.05）。结论尿毒症患者血清抑制小鼠骨髓红系祖细胞集落形成，随患者血清浓度的增加，抑制作用增强，具有剂量依赖性。
