19 Section 3 Gastritis n Ga’stritis may be acute or chronic inflammation of mucosa of stomach. - ! Several different histologic forms of gastritis have been identified. Most are likely secondary to the ingestion of various substances that cause injury to the gastric mucosa. Continued mucosal damage may initiate an immune-mediated reaction. Other factors, including allergic reactions, immune mechanisms, and hormonal factors, may play a part in the etiology of chronic gastritis. Chapter 2 Diseases of Digestive System

Ø Chronic gastritis is caused by a variety of diseases, including chronic superficial gastritis, chronic atrophic(萎 缩的) gastritis, and chronic hypertrophic(肥厚性) gastritis. l Chronic superficial gastritis is characterized histologically by infiltration(渗透) of the superficial mucosa and lamina propria(固有层 ) with lymphocytes, plasma cells, and fibrosis.
