异叶青兰对高原实验家兔骨髓幼红血岛影响的体视学研究

STEREOLOGICAL STUDY OF THE EFFECT OF DRACOCEPHALUM HETEROPHYLLUM BENTH ON THE BONE MARROW'S ERYTHROBLASTIC ISLANDS OF THE EXPERIMENTAL RABBITS AT HIGH ALTITUDE

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。

The bone marrow's erythroblastic islands (BMEI) of the experimental rabbits which were moved from plain to pl8teau (3900m) were studied by means of the stereological method. The experimental rabbits were divided into three groups: the plain group, the plateau-herb group and the plateau-contral group. The results showed that the volume and numerical density of BMEI of the plateau-herb group was higher,the avernge layer and the volume of BMEI of the plateau herb group were decreased than that of the plateau-control group which had the statistically remarkable (P＜0. 01). These results showed that the number of BMEI increased a Iots and the volume decreased after being given the herb for the experimental rabbits at high altitude. It was impy of BMEI and showed some protecting effection for BMEI of the plateau experimental rabbits.
