人间脑内部微血管构筑一组织化学显示法研究

应用碱性磷酸酶组织化学显示方法血管内皮进行染色,光镜观察7例人间脑內部的微血管构型。结果,发现动脉由前、后、内、外进入脑实质;由内侧进入的绝大多数动脉,进入丘脑申线核群形成终动脉;在动脉分布密度方面,丘脑前核群最少,而背外侧核、腹后外側核、中央正中核最多。依据核团形态及纤维方向,毛细血管也勾画出不同的轮廓。

A STUDY OF MICROANGIOARCHITECTURE OF THE HUMA NDIENCEPHALON WITH THE ENZYME HISTOCHEMICALIMETHOD

Micrcangioarchtecture of the human dieneephalon was studied by the enzyme histochemieal method (staining for alkalne Phosphatase activity). The results are as follows: Arteries Penetrate into the thalamus from the anterior, Posterior, lateral and medial surface; All these arteries send out branches to form a dense vascular network which can demonstrate the outline of the dorsalmedial nucleus and intraminar nuclear group; Many of these arteries are distributed over dorsolateral nucleus, ventral Fosterolateral nucleus and centromedian nucleus and a few over anterior nuclear group; Most of arteries Penetrating from the medical surface enter the midline nuclear group where they become terminal arteries.
