摘　　要：利用阿新蓝过碘酸雪夫试剂染色方法,研究了La3+长期暴露4个月对鲤鱼粘液细胞的影响。结果表明,La3+0.01、0.1、2、5mg/L组前肠和中肠粘液细胞密度,0.01、0.1mg/L组口腔上皮和后肠,以及0.1mg/L组鳃丝上粘液细胞密度与对照组相比均显著增加(P<0.01或P<0.05),而2、5mg/L组口腔上皮和后肠,0.01、2、5mg/L组鳃丝上粘液细胞密度与对照组相比,均无显著性差异(P>0.05)。镧能促进Ⅱ型粘液细胞、抑制Ⅰ、Ⅲ、Ⅳ型粘液细胞的形成。The studies were carried out on the effect of La^3 ＋ exposed for 4 mouths on the mucous cells of Cyprinus carpio Linnaeus by method of AB-PAS combined staining. The results showed that La^3 ＋ treatment with resulted in obvious increasing of mucous ceils 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 significant influence on mucous ceils 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. La^3＋ could promote the formation of type Ⅱ mucous cells and inhibit type Ⅰ , Ⅲand Ⅳ.
