从人体粪便中分离一株粪链球菌,并研究了它与动脉粥样硬化症之间的关系。实验结果表明,用粪链球菌免疫或口服粪链球菌可降低血清胆固醇或甘油三酯水平。粪链球菌免疫对HDL-ch有增加倾向,但无统计学意义;它可降低全血表观粘度和血浆表观粘度,但与对照组表观粘度比较则无差异。实验未发现粪链球菌免疫可减轻动脉粥样硬化病变。 A strain of Streptococcus faecalis was isolated from human feces and its relationship with atherosclerosis was studied. The experimental results show that immunization with Streptococcus faecalis or oral administration of Streptococcus faecalis can reduce serum cholesterol or triglyceride levels. Streptococcus faecalis immunization had an increased tendency for HDL-ch, but it was not statistically significant; it could reduce the apparent viscosity of whole blood and apparent plasma viscosity, but there was no difference compared with the apparent viscosity of the control group. The experiment did not find that immunization with Streptococcus faecalis could reduce atherosclerotic lesions.
