实验目的口腔粘膜白斑在老年口腔粘膜病中较常见,早期由于症状不明显,常被忽视。由于未及时有效防治,有少数可以癌变,其发病机制尚不十分清楚,如何防治也有待研究探讨。本实验的目的是试图在动物口腔内利用各种不同刺激,作为诱发因素,以造成类似人类口腔粘膜白斑病变的模型,以便密切观察此病的发生和发展规律,探讨其发病机理。 The purpose of the experiment Oral leukoplakia is more common in elderly oral mucosal diseases. Early symptoms are often overlooked due to insignificant symptoms. Due to the lack of timely and effective prevention and treatment, a few can be cancerous, and its pathogenesis is not yet clear. How to prevent and treat it remains to be studied. The purpose of this experiment is to try to use a variety of different stimuli in the mouth of animals as a predisposing factor to create a model similar to human leukoplakia in the oral mucosa so that the occurrence and development of the disease can be closely observed and the pathogenesis can be explored.
