[Study of 125I-interleukin-8 distribution in mice].

IL-8 was radiolabeled with 125I via Bolten-Hunter agent and the distribution of 125I-IL-8 in mice was determined in order to understand IL-8 behaviors in vivo. The percentage of 125I-IL-8 in blood, heart, liver, lung, kidneys, bone and spleen was obtained. The half-clearance of fast phase T1/2 alpha and slow phase T1/2 beta were 0.32 h and 8.01 h respectively. Most of 125I-IL-8 was excluded by kidneys.
