Objective: To investigate the changes of expressions of tubulin and endosome-lysosome in the neurons in hippocampus tissue of the mice after status epilepticus (SE), and to elucidate the change rule of microtubule and endosome-lysosome system in the process of delayed neuronal death. Methods: A total of 40 male ICR mice were divided into control group ( n= 7, given normal saline) and experiment group (w=33» give pilocarpine); the mice in experiment group met the SE standand were divided intoSE 1 d» SE 2 d, SE 3 d and SE 7 d groups according to the time after SE ( n=5). Nissl and Fluoro-Jade B (F-JB) staining methods were used to detect the damage of neurons in hippocampus tissue of the mice in various groups. The expression intensities of (3-tubulin? endosom protein Rab5 and lysosome constitutive protein LAMP1 and the percentages of (3-tubulin∗ Rab5 and LAMP1 positive areas in neurons in hippocampus tissue of the mice in various groups were detected by immunofluorescence method. The relationships between the expression of
