Methods: The N-methyl-N-nitro-N-nitroso-guanidine transformed eternalized human gastric mucosa epithelium GES-1 cell line was used in vitro as a model of gastric precancerous lesion. The medicated canine serum was prepared by feeding to the adult Beagle dog with Radix notoginseng extracts and obtaining the serum after 2-hour medication. MC cells were cultured with medicated canine serum or non-medicated canine serum for 72 hours.
