由组织肥大细胞和其他细胞释放的组织胺等化学介质的含量对引起呼吸道过敏性疾病具有重要意义。环核苷酸——环磷酸腺苷(cAMP)和环磷酸鸟苷(cGMP)对上述过程的调节有着密切的关系.环核苷酸能促进激素及其它生物活性物质对细胞代谢发生多方面的媒介作用。已知,在过敏反应时,由一些细胞中释放出来的组织胺,按照反馈作用原则,可抑制其它细胞释放这种介质。组织胺的这种
The content of chemical mediators such as histamine released by tissue mast cells and other cells is of great importance for causing respiratory allergic diseases. Cyclic nucleotides - cAMP and cGMP are closely related to the regulation of these processes.Cyclic nucleotides can promote the metabolism of hormones and other biologically active substances in many aspects of cell metabolism Media role. It is known that histamine released from some cells during anaphylactic reactions inhibits the release of this medium by other cells in accordance with the principle of feedback. Histamine of this kind
