Key words: differentiation of precursor cell , proliferation of spleen lymphocyte, purplish black glutinous rice

摘要： 选用紫黑糯米代表品种紫香糯861的皮层提取物，采用小鼠骨髓祖细胞分化试验，脾淋巴细胞增殖试验, 耐缺氧试验及游泳试验,评价其药理功能。紫黑米皮层提取物对骨髓抑制后的造血细胞有促进增殖、加快造血恢复的作用。紫黑糯米皮层提取物对环磷酰胺抑制后小鼠骨髓造血祖细胞CFU-GM 有促进早期恢复的作用,而这种作用可能是通过细胞直接作用而发生的。紫黑糯米种皮层有一定的镇静之功效，有促进机体免疫功能的作用。而对小鼠缺氧都无保护作用，对增强人体耐力方面没有显著的作用。
