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.

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(来源：A44B8787C论文网www.abclunwen.com)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。

Under the optimum conditions, the analytes could be separated within 17 min in a 75 cm length capillary at a separation voltage of 18 kV in a 10 mmol/L borate buffer (pH 8.2). A 300 μm diameter carbon disk electrode generated a good response at+ 0.95 V vs. saturated calomel electrode (SCE for all analytes. The relationship between peak currents and analyte concentrations was linear over about three orders of magnitude with detection limits (S/N=3) ranging from 78 μg/L to 110 μg/L for all analytes.
