ABSTRACT
Objective:
To probe into the long-term effect of La(NO3)3 fed orally on gast ric mucosa of rats.Methods:
The gastric mucosa of rats was studied after La(NO3)3 was administe red orally for a long-term,by the use of ordinary histological technology and m orphometry.Results:
In the groups of 20 mg·kg-1 and 10 mg·kg-1,the cytopl asma of more parietal cells lying in the top of the gastric gland was loose.Proporti on of cell types of the gastric gland was related to the doses. The acid mucus l evel of the mucous neck cells of male rats in the groups of 20 mg·kg-1 an d 10 m·kg-1 decreased. In the groups of 2 mg2kg-1, 0.2 mg·kg -1 and 0.1 mg*kg-1,the acid mucus level of the mucous neck cells of both male and female rats increased.Conclusion:
La(NO3)3 fed orally for a long-term could injure gastric muc osa in higher dose (20 mg·kg-1,10 mg·kg-1) but promote the protect ive action of the gastric mucosa in lower dose (0.2 mg·kg-1,0.1 mg·kg- 1).
