Abstract

Parotid salivas were collected from rats following electrical stimulation of either the sympathetic or parasympathetic nervous supplies. 2. The protein compositions of these salivas were compared using high performance ion-exchange chromatography (FPLC), SDS electrophoresis and biochemical assay. 3. Chromatography and electrophoresis indicated differences between the protein compositions of sympathetic and parasympathetic salivas. 4. Protein secretion derived solely from the exocytosis of parotid acinar cells cannot account for these differences.

摘要

分别通过电刺激大鼠的交感神经或副交感神经来收集腮腺唾液。2. 使用高效离子交换色谱法（快速蛋白质液相色谱法）、十二烷基硫酸钠电泳和生化分析对这些唾液的蛋白质组成进行比较。3. 色谱分析和电泳结果表明交感神经和副交感神经唾液的蛋白质组成存在差异。4. 仅由腮腺腺泡细胞胞吐作用产生的蛋白质分泌无法解释这些差异。
