Morphology of the regenerative process of certain neural elements at the place where the medullar scar was forming after a lateral hemisection was studied in the cat spinal cord at the level of the 11th thoracic segment. The observations were performed for 3 days--1 year. Methods of light and electron microscopy were applied. It was states that most of conductive tracts are capable for regeneration, nevertheless, the restoration of their integrity does not occur, since regenerating fibres have a marked tendency to form collaterals of the terminal type. The regeneration is accompanied by the formation of axodendritic and axo-axonic synapses whose role is not clear. The neural fibres regeneration is completed for 1 month on the background of a decreased neuroglial reactivity and contributes to its activation and purposeful proliferation which prevents the connective tissue growth. The neural fibres and terminals forming in the regenerative process are preserved for a year without any definite sign of degeneration if a well pronounced glial membrane is present.
在第11胸段水平的猫脊髓中，研究了在侧半横切后形成延髓瘢痕处某些神经元件的再生过程形态。观察持续了3天至1年。应用了光镜和电镜方法。结果表明，大多数传导束能够再生，然而，它们的完整性并未恢复，因为再生纤维有明显形成终末型侧支的倾向。再生伴随着轴树突和轴-轴突突触的形成，其作用尚不清楚。神经纤维再生在神经胶质反应性降低的背景下1个月内完成，并导致其激活和定向增殖，从而阻止结缔组织生长。如果存在明显的胶质膜，再生过程中形成的神经纤维和终末可保存一年而无任何明确的变性迹象。
