The injury of intestinal mucosa of mice with zinc-deficiency was inhibited by the Chinese herbal medicine (_??__??_, _??__??_, _??__??_, _??__??_, _??__??_, _??__??__??_), while the concentration of serum zinc in zinc deficient mice was not increased after administrations of the Chinese herbal medicine.

The Chinese herbal medicine (_??__??_, _??__??_, _??__??_, _??__??_, _??__??_, _??__??__??_) suppressed the injury of intestinal mucosa in mice with excess zinc administrations. The increase of serum zinc concentration with excess zinc administrations was also inhibited by administrations of the Chinese herbal medicine.

In recent years, the technological innovation and progress of endoscopic equipment have been remarkable, and various endoscopic observation techniques have been developed. Among them, representative techniques are magnified observation and narrow-band imaging. Magnifying endoscopy with narrow-band imaging (M-NBI) can visualize superficial microanatomies in the stomach. The normal morphology of the microanatomy visualized using M-NBI differs according to the part of the stomach. The vessel plus surface (VS) classification system has been developed as a diagnostic criterion for early gastric cancer using M-NBI, and its usefulness has been proven. Based on the VS classification system, a magnifying endoscopy simple diagnostic algorithm for early gastric cancer (MESDA-G), a simplified algorithm used for early gastric cancer diagnosis, was created. We aimed to describe the anatomic structure of the stomach that can be viewed using M-NBI and outline the principles and clinical application of the VS classification system and MESDA-G.
