摘要: 将肾上腺髓质组织块植入同种拟震颤麻痹大鼠模型脑内,移植物成活并发挥功能,受体大鼠的不正常行为获得改善。应用诱发荧光组化技术(SPG法)检查出植入的肾上腺髓质嗜铬细胞含儿茶酚胺。在成活的移植细胞中,有些仍保留典型的正常嗜铬细胞形态,而其他的却向着肾上腺素能神经元的形态变化,有的呈椭圆形甚或发出短粗的突起。应用荧光分光光度计分析受体脑组织各部的儿茶酚胺含量,移植区脑组织的多巴胺含量很高。移植物分泌的多巴胺不间断地弥散入纹状体,直接作用于多巴胺受体起作用。所谓“过量移植”比较常量移植更有效地校正动物的异常行为。本文结果对于将肾上腺髓质脑内移植术过渡到临床应用治疗震颤麻痹具有重要意义。

Abstract: Homotypic adrenal medulla were grafted into the denervated caudate nucleuses of the rats. It has been shown that the graft implanted into the rat brain survives and improves behavioral abnormalities.These grafted adrenal chromaffin cells contained catecholamines,as indicated by SPGmethod.Some cells retained the typical appearance of normal chromaff in cells,while other cells had undergone varying degrees of transformation toward the adrenergic-neuron phenotype.Most of those cells had become somewhat elongated or developed short coarse processes.Concentration of CA were studied by a spectrophotofluorometer using dissected host brain tissue. Concentration of dopaminc(DA)in the grafts were very high.So called “overamount”transplants were found to provide a more extensive behavioural recovery as compared with that receiving“anormalamount” The results of present paper were very significant for the future clinical application.
