Thirty 3-week-old male SD rats were assigned into 3 groups of 10 for the 4-week study. Difference between groups was statistically analyzed by Fisher's PLSD. P value less than 0.05 was considered significant. Plasma EPO concentration of zinc-deficient group was significantly decreased compared with control group, and pair-fed group was marginally decreased compared with control group (P=0.056). Kidney cortex EPO concentration was decreased in zinc-deficient group compared with pair-fed group. Kidney cortex EPO concentration in pair-fed group was higher than that of control group but the difference was not significant. No significant difference was observed in kidney medulla EPO concentration.

将30只3周龄雄性SD大鼠随机分为3组，每组10只，每组10只。组间差异采用Fisher‘s PLSD进行统计学分析。P值<0.05为显著。缺锌组大鼠血浆促红细胞生成素浓度较对照组显著降低(P=0.056)，成对喂养组较对照组略有下降(P=0.05)。缺锌组大鼠肾皮质EPO含量较对饲组降低。成对喂养组大鼠肾皮质EPO浓度高于对照组，但差异不显着。肾髓质促红细胞生成素浓度无显著差异。
