摘要:

通过在Zarrouk培养基中添加亚硒酸钠的方法获得了硒含量达758.6 μg/g的富硒螺旋藻。采用量子共振技术检测富硒螺旋藻的主要氨基酸、维生素及抗癌能力、免疫功能、抗高脂血症相关功能性指标的量价值,发现富硒螺旋藻以上各项指标的量价值均高于普通螺旋藻。同时考察富硒螺旋藻对急性高脂血症小鼠血脂水平的影响,给予小鼠连续2 周灌胃富硒螺旋藻,通过尾静脉单次注射400 mg/kg的Triton WR-1339建立急性高脂血症小鼠模型,18 h后检测小鼠血清中血脂水平。结果表明:与Triton WR-1339对照组相比较,富硒螺旋藻高剂量组小鼠的血清中甘油三酯(triglyceride,TG)、总胆固醇(total cholesterol,TC)、低密度脂蛋白胆固醇(low density lipoproteincholesterol,LDL-C)含量明显降低(P<0.01),高密度脂蛋白胆固醇(high density lipoprotein cholesterol,HDL-C)含量明显升高(P<0.01)。与普通螺旋藻高剂量组相比,富硒螺旋藻高剂量组小鼠的血清中TG、LDL-C含量显著降低(P<0.05),HDL-C含量显著上升(P<0.05)。富硒螺旋藻对急性高脂血症有良好的保健功效。

Abstract:

The enrichment of 758.6 μg/g selenium in Spirulina platensis was obtained by adding Na2SeO4 into Zarrouk
culture medium. Selenium-enriched Spirulina platensis was detected using quantum resonance spectrometer (QRS) to
analyze the major amino acids, vitamins, and measures of anticancer capacity, immune benefits and antihyperlipidemic
activity. The values of these parameters in selenium-enriched Spirulina platensis were higher than in the normal one. In
order to explore the effects of selenium-enriched Spirulina platensis on serum lipid levels of acute hyperlipidemic mice, we
established acute hyperlipidimic mouse model by single intravenous injection of 400 mg/kg Triton WR-1339 after the mice
were gavaged with selenium-enriched Spirulina platensis for two weeks. At 18 h after the injection, the mice were killed
and blood samples were collected for analysis. The results showed that the serum levels of TG, TC and LDL-C in mice
given high dose of selenium-enriched Spirulina platensis were significantly reduced whereas HDL-C concentration was
significantly increased compared with the model control group (P < 0.01). In the high-dose group, serum TG and LDL-C
values were also significantly reduced and HDL-C concentration was increased compared with the ordinary Spirulina
platensis group (P < 0.05). The above results indicate that Se-enriched Spirulina platensis gavaged to acute hyperlipidemic
mice has a significant hypolipidemic effect.

Key words: selenium-enriched Spirulina platensis, quantum resonance, acute hyperlipidemia
