The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

Results The choroid plexus, hypophysis, area postrema and pineal body, namely, circumventricular organs and ependyma as well as pia mater layers were stained by the HRP reaction products.The HRP reaction products were observed in the tissue space of membrane mucosa nasi, around the fila olfactoria and venules, and within the venules under the light microscopy and electron microscopy, also. Scintillation count showed that the radioactivity of the CVOs was higher than that of the background. The radioautography showed that the scattered grains of silver existed within the cells of neurocyte layer also.

This is a retrospective analysis of 194 patients with primary malignant brain tumor, who registered between January 1, 1970 and December 31, 1979 in cancer registration, Cancer Therapy Center, Veterans General Hospital, Taipei, Taiwan, R.O.C. There were 36 cases of glioblastoma multiforme, 86 cases of malignant astrocytoma (grade Ⅲ and a few grade Ⅱ), 22 of medulloblastoma, 12 of oligodendroglioma, 11 of ependymoma or ependymoblastoma and 27 cases of other types. There were 141 male cases with ages ranging from ito 81 years with a mean of 33.3±19.3 and median of 34 years.

自1970年1月至1979年12月台北荣民总医院癌病治疗中心癌病登记组共登记了194例原发恶性脑瘤其中多形神经胶母细胞瘤有36例，第二级及第三级星细胞瘤有86例，神经管胚细胞瘤有22例，间胶质母细胞瘤有12例，室管膜瘤或室管膜胚细胞瘤(ependy-moblastoma)有11例，其他有27例。

About 48%(90/194) were below 29 years of age. Ninety-nine of 194 cases had either radiotherapy alone or supplementary treatment with radiotherapy following surgery. We analyzed multiple prognostic factors. The factors of importance included postoperative radiotherapy; female in glioblastoma multiforme; the primary tumor dose above 5000 rads and/or whole brain irradiation in malignant astrocytoma and glioblastoma multiforme; the primary tumor dose above 4500 rads in ependymoma, medulloblastoma and oligodendroglioma; and spinal axis irradiation above 2000 rads in ependymoma and medulloblastoma that produced a better prognosis than in other groups.

While the tissue spaces surrounding a few blood vessels wasAl and Fg positive,no Al or Fg positive cells were observed.In antemortem injurygroup,diffuse subarachnoid hemorrhage,cerebral edema,swelling or pyknotic neu-rons could be observed.The axons showed irregular swelling and disconnection at1～3h,marked swelling and disconnection at 6h,and retraction ball at 15h whichwas more remarkable at 24h after injury.The space between myelin sheaths andaxons was increased at 3～6h after injury.Tortuous and wavelike myelin sheathswhich adhered on axons incompletely,or even peeled off could be found from 15hto 24h after injury.Perinuclear lysis of Nissl bodies began at 24h after injury.Thenumber of GFAP positive cells in cerebrum and brain-stem increased significantlyfollowed by decrease,and then increased again,but the time courses of the changesin different areas of brain were not same.Al and Fg positive neural cells,mainlysurrounded blood vessels,with diffuse or peripherally distributed positive matter incytoplasm could be observed at 0.5h after injury.The number of Al or Fg positivecells and the intensity of immunoreaction increased with the time of injury.The areaof SYN positivity in medulla oblongata and pons decreased notably 3～6h afterinjury,then return to normal levels and continued to 24h after injury.

生前损伤组，可见广泛蛛网膜下腔出血，脑组织水肿，神经细胞肿胀，晚期神经元固缩；伤后1～3h见部分神经轴突不规则增粗、断裂，伤后6h断端膨大，伤后15h可见收缩球，至伤后24h更为明显；伤后3～6h可见部分神经髓鞘与轴突之间的间隙增宽，伤后15h髓鞘明显曲折，不完全附着在轴突两侧，甚至剥脱，持续到伤后24h；核周尼氏体减少在伤后24h才开始出现；同一部位的GFAP阳性细胞数目随损伤时间发生改变，先增多（最早在伤后0.5h），达到高峰后减少，其后又有增多趋势，但不同部位的GFAP阳性细胞数目增减的时间过程不尽相同，同时，大脑中的GFAP阳性细胞数目也有改变；伤后0.5h，可在脑干组织中见到Al和Fg阳性神经细胞，主要位于血管周围，阳性物在胞浆中呈弥散性分布，但部分细胞的阳性物仅分布于靠近胞膜的胞浆中而呈环状，随损伤时间延长，阳性细胞数目增多，反应强度增加；伤后3～6h，延髓及桥脑中的SYN阳性物面积减少，其后恢复到正常水平，并持续到伤后24h。

Results The results showed hyper fluorescence was located in tectorial membrane, spiral ganglion, organ of corti. There were less intensity of fluorescesce among the atria vascularis.
