NO3-N is the most popular and safest nitrogen source to Spirulina, the suitable concentration is about 11mmol/L, which can speed the growth rate and reduce the cost of cultivation as well. NH4-N of the suitable concentration can enhance the growth of Spirulina,but overhigh concentration will cause the ammoniac toxicosis, the suitable concentration of NH4-N is about 1.27～2.57mmol/L.

NO3-N对螺旋藻是最为通用和安全的氮源，但添加浓度以11mmol/L左右最为适宜，既可满足藻体的最佳生长需求又可降低养殖成本；适宜浓度的NH4-N可促进螺旋藻的生长，浓度过高则会造成NH3中毒，NH4-N的添加量以1.27～2.57mmol/L范围最为适宜。

After treatment for 4 weeks, the parameters, including blood glucose, glycosidase, maltase, total cholesterol, triglyceride, were determined.

复方中药糖脂清各剂量组，给药前与给药4周后相比各剂量组均可降低血糖，同时降低KK-Ay小鼠小肠的蔗糖酶与麦芽糖酶的活性、血清中总胆固醇和甘油三酯的含量。
