环-磷酸鸟苷(cGMP)是近几年来在生物医学中极受注意的重要活性物质之一。它和环-磷酸腺苷(cAMP)一起,对细胞的生长、繁殖及生理活动起着重要的调节作用。根据文献报导及我们自己和兄弟单位协作研究的初步结果,它们和中医“虚证”及一些重要疾病如急性心肌梗塞、慢性肾炎等都有重要关系。但cGMP在体内含量甚低,测定较难。本文报导抗原制 Cyclic-guanosine monophosphate (cGMP) is one of the most important active substances in biomedicine in recent years. Together with cyclo-adenosine monophosphate (cAMP), it plays an important regulatory role in cell growth, reproduction and physiology. According to the preliminary results reported in the literature and collaborative research between ourselves and our brothers, they have important relationships with TCM “deficiency syndrome” and some important diseases such as acute myocardial infarction and chronic nephritis. But cGMP content in the body is very low, the determination is more difficult. This article reports the antigen system
