Methods A retrospective analysis was performed for images of CT,MRI and DSA of 12 patients with intracranial venous angiomas.In all cases,7 cases male,5 cases female,age ranged from 8 years old to 72 years old.All patients underwent the examinations of CT,MRI and/or DSA.Results All 12 patients had single lesion.In these cases,there were 6 cases （50%） located in cerebella,6 cases （50%） located in cerebra including 3 cases （25%） in lobus frontalis and 3 cases （25%） in lobus parietalis.Most patients had slight clinical symptoms and were detected the lesions accidentally when they were examined for other diseases.Compared the imaging features of CT,MRI and DSA,conventional CT scan was negative,but there were characteristic images which was "dendritic" sign in contrast-enhanced CT and MRI,and typical findings of "caput medusae"sign in venous phase of DSA.

结果 颅内静脉血管瘤均为单发；6例（50%）位於幕下小脑实质内，6例（50%）位於幕上额叶（3例25%）、顶叶（3例25%）脑实质内；患者临床症状轻微，多为合并其他病变检查时偶然发现；CT、MRI及DSA的影像比较，CT平扫为阴性，CT增强扫描与MRI平扫呈特征性表现，即树枝征，DSA静脉期可见典型表现蛇头征。

By immunohistochemistry and semiquantitative RT-PCR analysis, we were the first to demonstrate that AdM mRNA and immunoreactive AdM exists in the rat brain distributed in cerebral cortex, paraventricular tissues, hypothalamus, mesencephalon, medulla oblongata and cerebellum, and AdM mRNA was also found in the human brain.

We introduced improved primary mixed glial culture and different-attachment method to isolate and purify the OPCs, the cells were proliferated in serum-free medium, flow cytometry and immunohischemistry methods were employed to estimate the purity of cultured OPCs. Their abilities of differentiation and expression of trophic factors were identified by RT-PCR and immunostaining. Several methods including TUNEL and MTT were adopted to estimate the protective effects of conditioned culture medium from oligodendrocyte lineage cells on the primary cultured cerebellar granule neurons. Intravitreal transplant of OPCs, combined with retrograde fluorescent labeling the superior colliculus and intraorbital optic nerve transection, were used to investigate the protective effects of OPCs on the axotomized RGCs in vivo. Intravitreal transplantof OPCs or NSCs on the newborn rats, and retinal transplant of OPCs on the young rats were performed, to observe the myelin formation in the retina at different stages after cellular transplantation. Optic nerve transection was carried out on some rats with myelinated retinae, to study the influence of myelination on the injuried RGCs.
