Healthy male Wistar rats were prepared as model of precancerous lesion of gastric mucosa. The tongue, pH of tongue surface, dropped cells from tongue fur, histology of tongue. and corresponding gastric mucosa, pH of gastric juice, mucosal histological changes in both groups were observed. Results revealed that, in the rats with precancerous lesion, the tongues were bare or only with little fur, dark purplish tongue with petechia. pH of both tongue and gastric juice were high, which were both coincided with the syndrome type of asthenic gastric - qi and blockage of collaterals by stagnant blood.

Objective:To investigate the suppressed e ects of total hedysarum polybotrys saccharide(THPS) alone and THPS combined with Cytoxan(CTX) on tumor-bearing mice and its mechanisms.Method:Kunming mice inoculated with S180 were given low,moderate and high dose THPS and THPS combined with CTX by intraperitoneal injection.Fourteen day later,tumor weight,inhibition rate,thymus index and spleen index were observed.CD4+ and CD8+ lymphocyte were counted though the ow cytometer.Results:Compared with the control,the moderate dose THPS showed signi cantly suppressed e ect on the growth of S180 tumor(P
