Complex Carbohydrate Histochemistry of the Surface and Gastric Pit Epitheliums of the Japanese Macaque

Abstract

Summary: Complex carbohydrate histochemistry of the surface and gastric pit epitheliums of the Japanese macaque was performed and the following conclusions were made:
1. Reactions to neutral and acid mucopolysaccharides are generally moderate, however, reactions to neutral mucosubstances in the body and pylorus are fairly clear.
2. Neutral mucopolysaccharides do not surpass weak acid ones.
3. Reactions to strong acid mucopolysaccharides are extremely faint.
4. Complex carbohydrates in the surface and gastric pit epitheliums bear some resemblance to those of type H mucous cells (Imai et al.).
5. There is no difference in the degree of reaction between the surface and gastric pit epithelium; however, Tsujimura recognized such a difference in the dog.
