摘要
It has been known that cytotoxic-activated macrophages release an unstable vasorelaxing substance, nitric oxide. We have found that a more stable relaxing factor is released from those cells. This factor seems to be synthesized from L-arginine. It acts through the activation of soluble guanylate cyclase without affecting membrane potential. It has little charge at nearly neutral pH, and its molecular weight is <500.
