[Histopathology of spleen deficiency syndrome of chronic atrophic gastritis and its ultrastructural changes].
Pathologic change of gastric mucosa in 247 CAG patients of Spleen Qi (Yang) Deficiency (QYD) and Spleen-Stomach Yin Deficiency(YD) Syndrome were observed. The surface of gastric antrum mucosa of 26 patients with scanning electron microscope as well as the gastric mucosa of 34 patients with transmission electron microscope was observed for their intracellular structure. It was found that the CSAG and CAG I of Spleen QYD amounted to 165 cases (66.8%), and CAG II and III of Spleen-Stomach YD amounted to 34 cases (64.2%). It denoted that the Spleen QYD belonged to mild case, while the Spleen-Stomach YD belonged to severe case. The mitochondria of all kinds of gastric antrum mucosa cells showed retrograded degeneration, the pathologic basis of Spleen Deficiency of CAG, those of Spleen-Stomach QD had sparse broken and swollen mitochondria (82.3%), while the 53.3% of Spleen-Stomach YD displayed vacuolation as its predominant change. The different severity of retrograde degeneration and damage of mitochondria yielded various stage in atrophy of gastric mucosa which was the basis of Syndromes evolution from Defi. to QYD and then YD. Inflammatory change of the gastric mucosa was predominant in Spleen-Stomach YD (45.3%), and far less in QYD (27.1%), P < 0.01.
