A study of Helicobacterium pylori and prevention and treatment of chronic atrophic gastritis.

The rate of detection of helicobacterium pylori (HP) in chronic atrophic gastritis (CAG) is 67%, HP being a slightly aerobic Gram-negative bacterium. Some drugs of traditional Chinese medicine (TCM) for clearing away heat and for removing blood stasis have significant effect on inhibition of HP. The drugs in both the recipe for nourishing yin, clearing away heat and invigorating blood circulation and the recipe for clearing away heat and invigorating blood circulation have inhibitory action on HP in vitro. All patients with CAG have symptoms of damp-heat and blood stasis. Radix et Rhizoma Rhei and Rhizoma Coptidis Decoction for Purging Stomach-Fire ([symbol: see text]) as the basic recipe and "Huo Wei" ([symbol: see text]) No. 2 recipe as the supplementary have good inhibitory effect on HP in inhibition tests. The results show several forms of the medicine all resulted in significant good therapeutic effect.
