前列腺素(Prostaglandins简称PGS)是一族廿碳多不饱和脂肪酸,几乎存在于人体一切组织中,含量微,代谢快。近二十多年来国内外研究资料表明,PGS是人体内一种重要生理活性物质,参与多种器官系统的生理生化过程,显示多方面生理功能和病理生理的联系。一般认为,PGS是通过改变“第二信使”——cAMP的浓度来发挥其生理效应的,它与cAMP、cGMP的功能密切相关。 Prostaglandins (Prostaglandins referred to as PGS) is a group of cesium-carbon polyunsaturated fatty acids, which are found in almost all tissues of the body. The research data at home and abroad in the past two decades shows that PGS is an important physiologically active substance in the human body and participates in the physiological and biochemical processes of various organ systems, showing the relationship between many physiological functions and pathophysiology. It is generally believed that PGS exerts its physiological effects by changing the concentration of “second messenger”-cAMP, which is closely related to the functions of cAMP and cGMP.
