摘要: 通过口腔滴注表皮生长因子(EGF),观察小鼠舌上皮细胞生长和表皮生长因子受体(EGF-R)的表达,研究EGF影响舌苔形成的分子机制。舌组织经HE染色、EGF-R SABC免疫组化染色和图像分析数据处理系统(CMIAS-98A多功能图象分析仪)进行分析。结果表明,EGF可能通过EGF-R机制进行信号传导促进小鼠舌上皮细胞增生、舌粘膜增厚、EGF-R表达增多。

Abstract: To research the signal mechanism between epidermal growth factor (EGF) and tongue-coating formation,the mice tongue mucosa cell growth with EGF-R expression was observed after droping EGF to mice mouth cavity.HE、EGF-R immuno-histochemistry (SABC) and by data handles system (CMIAS-98A) to proceed the image analysis were used. The results showed that EGF promotes the thickening of tongue mucosa in experiment mice,and the base layer cells and the EGF-R expression of tongue mucosa were increased.The EGF might influence the tongue-coating formation by the signal conduct mechanism of EGF-R.
