The trial model with chicken encephalomalacia was set up by using the feed of low congtent of V〓 and supplying excessive unsaturated fatty acid in feed for studying the molecular mechanism of chicken encephalomalacia in the study. On the basis of observing the symptom and postmortem examination in clinic and determining the content of V〓, the bodyweight, the weight of cerebrum and cerebellum, the focus of the study was on follows which were relative to neuropathic injury. The concentration of free radical and the function of antioxidant defense system of chicken with encephalomalacia were determined systematically.

A series of indexes reflecting free radical changes, anti-oxidations, Immune function, endocrine function was studied by Chemiluminescence method, immunoturbidimetry, ANAE dye method, micro-hemagglutination inhibition test and radio immunoassay in the chicken with encephalomalicia induced by giving the feed being deficient in VE and extra fish oil artificially. The pathological changes including microscopic and ultramicroscopic changes in the relative organs and tissues were observed.

本实验以一日龄150只海兰兰蛋鸡为实验动物，用低维生素E且添加鱼油日粮饲喂雏鸡，复制脑软化症动物模型，采用化学发光法、免疫浊度测定法、酸性α-醋酸萘脂酶染色法、微量血凝抑制试验、放射免疫测定技术等方法系统地检测了脑软化雏鸡的自由基代谢和抗氧化功能、红细胞免疫功能、细胞免疫功能、体液免疫功能及非特异性免疫功能等指标，并对患雏病理组织进行了显微及超微结构观察。

结论伽玛刀治疗脑软化灶导致的癫痫是有效的，而且无痛苦、无出血、无感染、无死亡、术后恢复快，其中以局限性发作效果最好；对脑软化灶导致癫痫的患者行SPECT检查，只有发作间期放射性分布减低和发作期增高在同一脑区才被确认为致痫灶；以上方法可明显缩小靶区体积。
