生物体中的离子化钙是重要的生理活性物质,许多重要的生理过程与钙离子的活度(或浓度)有密切关系。钙离子参与了骨的形成和吸收、神经传导、肌肉收缩、心脏的输导和收缩、大脑功能、肾小管功能、肠的分泌和吸收、血液凝结、膜和毛细管的渗透性、酶功能以及各种内分泌腺的激素分泌等各种生理机能。目前已证实许多疾病与体内钙离子变化有关。因此,生物体中钙离子的研究成为生理、生化、病理及临床等学科感兴趣的课题。近年来,许多学者报道了用钙离子选择性微电极进行钙的生理、病理研究。本文作者曾研制了双-[二(对辛基苯基)磷酸]钙为活性物质、苯基瞵酸二辛酯为增塑剂的 PVC
Ionized calcium in organisms is an important physiologically active substance. Many important physiological processes are closely related to the activity (or concentration) of calcium ions. Calcium ions are involved in the formation and absorption of bone, nerve conduction, muscle contraction, heart conduction and contraction, brain function, renal tubular function, intestinal secretion and absorption, blood coagulation, membrane and capillary permeability, enzyme function, Endocrine glands hormone secretion and other physiological functions. Has confirmed that many diseases and changes in the body of calcium. Therefore, the study of calcium ions in living organisms has become a topic of interest in physiological, biochemical, pathological and clinical disciplines. In recent years, many scholars reported the use of calcium ion selective microelectrode calcium physiological and pathological studies. The author of this paper has developed a double - [bis (p-octylphenyl) phosphate] calcium as the active substance, phenyl dioctyl phthalate as a plasticizer PVC
