自体移植脾组织的血流量及形态学的变化

Dynamic observation on the morphology and regional blood flow of the autotransplanted splenic tissue

对自体移植脾的组织量和血流量以及形态学进行动态观察。实验用大鼠分别于术后３、５、７、１２月通过生物微球法对每只动物保留１／４原位脾和移植半脾进行检测。结果得出，自体移植牌组织各时相点的单位重量血流量、血容积和吞噬指数与原位保留的相差不显著、原位保留的残脾重量代偿性增加，但移植脾组织量明显减轻，因而移植脾的绝对血流量也相应减少，揭示移植脾组织应尽量增多。镜检移植脾组织随着时间推移显示正常结构。

The regional blood flow measurement and morphological observation of the autotransplanted splenic tissue were carried out in 20 Wistar rats, It was found that the regional blood flow,blood volume and phagocyte index of the implanted tissue at respective phase were similar to that of the spleen in situ. The weight of the implanted splenic tissue did not regenerate to the originally implanted amount but markedly decreased.So it's absolute blood flow relatively reduced. It suggests that amount of the autotransplanted splenic tissue should be large enough as possible. By microscopical dynamic observation on the implanted tissue the splenic follicles were seen again,profile of the red and white pulps was clear.Macrophages were increasing. It showed that the autotransplanted splenic tissue could gradually recover to normal.
