應(yīng)用半固體瓊脂培養(yǎng)法和MTT法研究了極大螺旋藻胞內(nèi)多糖對(duì)人血癌細(xì)胞U397和HL-60的影響。實(shí)驗(yàn)結(jié)果顯示,對(duì)體外生長(zhǎng)的U937細(xì)胞有促進(jìn)生長(zhǎng)的作用,而對(duì)體外生長(zhǎng)的HL-60細(xì)胞有抑制生長(zhǎng)的作用。提示極大螺旋藻胞內(nèi)多糖對(duì)人的血癌細(xì)胞的生長(zhǎng)有明顯的影響。

The effects of polysaccharides from Spirulina ma.zima on the growth of human leukemia cells were studied by semi-solid agar culture and MTT staining. The results showed that the polysaccharides could significantly promote the growth of U937 cells and retard the growth of HL-60 cells,especially at concentraions of 60 and 15 nmol/L, which suggested that the polysaccharides from Spirulina maxima could obviously affect the growth of human leukemia cells.
