本文应用体视学方法，对平原移居高原（海拔3900m）实验家兔骨髓幼红细胞造血岛的形态进行了研究，实验动物分子原组，高原给药组和高原对照组。结果发现：高原给药组骨髓幼红细胞造血岛作积密度（Vv）和数密度（Nv）均高于高原对照组；而高原给药组幼红细胞血岛平均层次和体积均低于高原对照组；差别有显著意义（P＜0．01）。这些指标说明用药后红血岛数量增多，体积减小。结果提示，异叶青兰对低氧环境动物骨髓幼红血岛有一定的作用，可使幼红细胞造血岛增殖或减少的变化波动较平缓。
In this paper, the morphology of the hematopoietic islands of rabbit bone marrow erythroblasts in the plateau (3900m above sea level) was studied using stereological methods. The experimental animals were of the primitive group, the plateau administration group and the plateau control group. The results showed that the hematopoietic islands of platelet-treated group had higher Vv and Nv than that of the plateau control group, while the average level and volume of the blood islands of plateau treated group were lower than that of the plateau control group. The difference was significant (P<0.01). These indicators indicate that the number of red blood islands increased and the volume decreased after administration. The results suggest that C. heterophylla has a certain effect on juvenile red blood islands in hypoxic environment, and can make the change of proliferation or decrease of hematopoietic islands of erythrocytes more gentle.
