Morphological changes and proliferative activity of the neural retina cells after the neural retina detachment were studied in the newts subjected to microgravity in a clinostat. According to theoretical calculations, simulated microgravity could vary from 3.21 x 10(-2) to 8.05 x 10(-3) g. These conditions had a positive effect on morphological and functional restoration of the neural retina according to various criteria. Specifically, the increased number of Mullerian glial cells, increased relative volume of the plexiform layers, decreased mortality of the detached neural retina cells and increased redifferentiation of the retinal pigment epithelium and reattachment of the neural retina were observed. These changes were mainly found in the dorsal and central areas of the neural retina.
在回转器中对蝾螈进行微重力处理后,研究了神经视网膜脱离后神经视网膜细胞的形态变化和增殖活性。根据理论计算,模拟微重力可在3.21×10⁻²至8.05×10⁻³g之间变化。根据各种标准,这些条件对神经视网膜的形态和功能恢复有积极影响。具体而言,观察到米勒胶质细胞数量增加、神经纤维层相对体积增大、脱离的神经视网膜细胞死亡率降低、视网膜色素上皮细胞再分化增加以及神经视网膜重新附着。这些变化主要发生在神经视网膜的背侧和中央区域。
