Nitric oxide production and arachidonic acid metabolism in platelet membranes of coronary heart disease patients with and without diabetes.

Aim: To evaluate the levels of nitrite (NO(-)(2)) and nitrate (NO(-)(3)) ions and the incorporation of [(3)H]arachidonic acid (AA) into phospholipids of platelet membranes from coronary artery disease (CAD) patients with and without diabetes (NIDDM).

Subjects And Methods: Eighteen CAD patients (group A), 18 CAD patients with NIDDM (group B), and 20 healthy controls (group C) without dyslipidemia, peripheral vascular disease and hypertension were included in the study. The groups were matched for age, sex and body mass index.

Effect of cerebrocrast on the function of human platelets and release of the arachidonic acid from plasma membrane.

Diabetes mellitus (DM) is accompanied by several cardiovascular complications such as coronary artery disease, atherosclerosis, hypertension, cerebral and myocardial infarction, etc. DM induces the alteration of platelet functions including activation, hyperaggregation, adhesiveness, and formation of thrombi. Release of AA from phospholipids of the PM, synthesis of TxA(2),PGE(2), activity of PLA(2), and PLC are increased in the platelets of the DM patients.
