Salt balance is essential for the survival and functioning of all organisms. The factors that control salt and water balance in freshwater mussels are under investigation here. These organisms have a simple control system involving nervous and local cellular control mechanisms. There is evidence that serotonin, a common nervous system transmitter substance, stimulates sodium and calcium transport. The gills in mussel are the principal sites of transport and will be used in this study. The transport of nervous transmitters (including serotonin), prostaglandins, and arachadonic metabolites will all be examined under various conditions. The data obtained in this research will shed light on the cellular mechanisms controlling sodium and calcium transport. This will enhance our understanding of calcium transport, deposition, and mobilization as it relates to overall salt and water balance.

盐的平衡对所有生物的生存和功能至关重要。这里正在研究控制淡水贻贝体内盐分和水分平衡的因素。这些生物有一个简单的控制系统，包括神经和局部细胞控制机制。有证据表明，血清素，一种常见的神经系统递质，刺激钠和钙的运输。贻贝的鳃是运输的主要部位，将在本研究中使用。神经递质（包括血清素）、前列腺素和花生代谢物的转运都将在各种条件下进行检查。本研究获得的数据将揭示控制钠和钙运输的细胞机制。这将增强我们对钙运输、沉积和动员的理解，因为它与盐和水的整体平衡有关。
