Abstract

PHYSIOLOGICAL EFFECTS OF NITRIC OXIDE: The generation of nitric oxide by the vascular endothelium maintains a vasodilator tone that is essential for the regulation of blood flow and pressure. In the brain, nitric oxide acts as a mediator of cell-cell signalling. In the peripheral nervous system nitric oxide is also released from many nerves previously classified as non-adrenergic and non-cholinergic. Thus this simple gaseous molecule performs a wide variety of physiological functions. POTENTIAL FOR THERAPEUTIC MANIPULATIONS: Impaired production of nitric oxide can be countered by the administration of nitric oxide donors (in hypertension, atherosclerosis, gastrointestinal and genitourinary disorders) or by inhalation of nitric oxide gas (in chronic pulmonary hypertension or adult respiratory distress syndrome). The biggest challenge is to develop strategies that target the cytotoxic and damaging actions of nitric oxide without interfering with its essential protective functions.

Cardiovascular Homeostasis

Cardiovascular regulation and homeostasis is important in maintaining health and dysfunction may lead to cardiovascular diseases. Nitric oxide and vascular endothelium are one of many molecules involved in the homeostatic mechanism. Here is the latest research on cardiovascular homeostasis.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
