Nitric oxide is an important physiological regulator in the immune system, nervous system and cardiovascular system, and it can cause relaxation of vascular smooth muscle in vivo, and can regulate myocardial blood supply, balance blood pressure, reduce vascular resistance, prevent angina pectoris, strengthen lung function, control hypertension, etc. by vasodilating and dilating blood vessels to ensure adequate blood supply to heart, and it has been approved in some areas as a pulmonary vasodilator for treating neonatal diseases.
Nitric oxide is also a nerve conduction substance, which can transmit the information among nerve cells, promote the communication among nerve cells, has close relation with the centers of brain learning, memory, sleep, coordination and the like, can achieve the effects of promoting brain learning, improving memory, improving sleep quality, releasing pressure and the like when being applied to a human body, and can influence the digestive function of stomach and intestine, even erection of genitals, relieving menstrual pain and preventing senile dementia.
Nitric oxide also has the effects of reducing the resistance of insulin and improving the sensitivity of insulin to blood sugar, thereby accelerating the metabolism of blood sugar in vivo, being used for improving diabetes and complications thereof, preventing cancer and inhibiting the growth of tumor, enhancing the immunocompetence of macrophage by regulating the cytotoxicity of macrophage on microorganism and tumor cells to achieve the purposes of preventing and resisting cancer, being also beneficial to diminishing inflammation and relieving pain, and improving different pathophysiological states such as septic shock, hypertension, apoplexy, neurodegenerative diseases and the like besides mediating normal physiological functions of nitric oxide, thereby playing an important role in the field of medical health.
