Abstract:
Objective To explore the relationship between immunohistochemistry of LN,FN,p53 and TIMES in human brain glioma(BG). Methods Transmission electronic microscope(TEM) and immunohistochemistry were used to investigate the morphological characteristics of micrangiums in BG and the expression of LN,FN,p53 in BG and intracranial metastatic tumors. Results 1.It was found that base laminas beneath endothelial cell with locally or extensively thickened were intact and continuous in BG.The increasing thickness of BM was consistent with the staining of LN and FN and related to p53 immunostaining.BM of p53-protein positive cases grew thicker than that of p53-protein negative ones.2.Micrangiums BM in all BG were positive for LN and FN.The more malignant the BG was,the stronger the LN and FN staining became and the thicker the blood vessel walls grew(P0.05).Conclusion One of the reasons that BMs in TIMES in BG thicken may be the over expression of LN and FN of brain micrangium endothelial cells.Also,the influence of p53 on TIMES is associated with the functional state of endothelial cells.Micrangiums endothelial cells may be play a role in regulating TIMES.
