CA II and AQP5 expression levels were determined by immunofluorescence and immunoblotting, while CA activity and Na, K-ATPase activity by a colorimetric assay. Anhidrotic mice treated by topiramate did not differ from controls in average secretory coil diameter, CA II expression, CA activity and Na, K-ATPase activity.

应用免疫荧光和western blot技术发现：小鼠在托吡酯处理后泌汗减少，碳酸酐酶同功酶II型(carbonic anhydraseII，CAII)蛋白表达未出现显著变化，但汗腺组织胞膜的水通道蛋白-5(aquaporin-5，AQP5)表达量下调。

In summary, our results indicate that hypohidrosis is a frequent adverse effect in children with topiramate therapy. Younger age and hot weather rather than drug dosage are independent risk factors for topiramate-associated hypohidrosis. The resultes also rule out the possibility that topiramate act on its known mechanisms of action, such as potentiating GABA activity at GABAA receptors and antagonizing the AMPA/KA subtype of glutamate receptor in the secretory cells of sweat glands to inhibit sweat secretion. Our data also suggest that topiramate impairs sudomotor function in mice and leads to a significant reduction in AQP5 expression in sweat glands of anhidrotic mice, thus raising the possibility that dysregulation of AQP5 may contribute to topiramate related hypohidrosis. CA inhibition may not be an important contributor since CA II expression and CA activity was intact in anhidrotic mice treated with topiramate.

综合全部实验结果，本研究提示：夏季和低龄是托吡酯引起泌汗障碍的主要危险因素，而托吡酯剂量对泌汗功能的影响较小；托吡酯可以抑制小鼠汗液的分泌，小鼠的年龄并不影响这种抑制作用，但托吡酯对小鼠体温无明显影响；托吡酯并不是通过对GABAA受体及AMPA和KA两种谷氨酸受体亚型的作用而在汗腺分泌细胞抑制泌汗；托吡酯不影响汗腺形态及Na，K-ATP酶活性；汗腺分泌细胞的AQP5功能失调可能与托吡酯引起的泌汗障碍密切相关，而碳酸酐酶抑制作用并不是泌汗功能损害的主要原因。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
