Abstract:The studies were carried out on the effect of La3+ exposed for 4 months on the mucous cells of Cyprinus carpio Linnaeus by method of AB-PAS combined staining. The results showed that La3+ treatment with resulted in obvious increasing of mucous cells densities in former intestines and middle intestines in the groups treated with 0.01, 0.1, 2 , 5 mg/L LaCl3 and in oral cavity and retrial intestine in 0.01, 0.1 mg/L and in gill in 0.1 mg/L (P<0.01 or P<0.05), however, expressed no significantly influence on mucous cells densities in oral cavity and retrial intestine in 2, 5 mg/L and in gill in 0.01, 2, 5 mg/L(P>0.05) in comparison with control group. La3+ could promote the formation of type Ⅱ mucous cells and inhibit typeⅠ, Ⅲ and Ⅳ.
