Abstract:
Objective To investigate the chemical preventive effect of matrine on ethyl nitrate nitroguanidine nitrate induced gastric cancer in rats. Methods 100 male Wistar rats were selected and randomly divided into four groups,each had 25 rats ,treated with different drugs respectively.Rats in the negative control group (group A)freely drunk water;each rat in gastric carcer model group (group B)drunk ethyl nitrate nitroguanidine nitrate (ENNG)1.5 mg/d by themselves;gastric cancer model rats of experimental group (group C)drunk matrine 150 mg/(kg · d)ethyl nitrate nitroguanidine nitrate (ENNG)150mg/(kg·d)by themselves;negative control group (group D)rats drunk matrine for injection 150 mg/(kg·d)by themselves.Rats were killed after 24 weeks,rats were observed on gastric mucosa change by naked eye and microscope ,and detected proliferating cell nucleus antigen (PCNA)of stomach tissue ,levels of serum transforming growth factorβ1 (TGF-β1 )and B cell lymphoma/leukemia-2 (Bcl-2).Results Canceration rate [64.00% (16/25)]of the rat gastric mucosa in Group B was significantly higher than that in group C [12.00% (3/25)],and the difference was statistically significant (P<0.05 );PCNA,TGF-β1 and the Bcl-2 level of rats in group C was lower than those in group B,and the difference was statistically significant (P<0.05 );after raising 24 weeks,change rate of gastric mucosa atrophy and hyperplasia in group B were significantly higher than those of group C,and the difference was statistically significant (P<0.05 );after raising 24 weeks,there was no cancerous changes on gastric mucosa in group A and D ,and the change of gastric mucosa atrophy and hyperplasia had no obvious difference,there was no statistically significant difference.Conclusion Matrine could inhibit rat gastric cancer induced by ENNG by lowering PCNA,TGF-β1 and the Bcl-2 levels,which provides evidence for the potential chemical preventive effect on human gastric cancer.
