For saturable, propranolol-sensitive [3H]DHA binding, Bmax = 0.374 +/- 0.063 fmol/microgram protein; KDHA = 12.5 +/- 2.4 nM from Scatchard analysis. For saturable, atropine-sensitive [3H]QNB binding, Bmax = 0.403 +/- 0.053 fmol/microgram protein; KQNB = 15.4 +/- 0.7 nM. The order of potency of unlabeled adrenergic agonists in competition for [3H]DHA sites was isoproterenol greater than epinephrine greater than norepinephrine. For unlabeled cholinergic agonists competing for [3H]QNB sites, the order was oxotremorine greater than acetylcholine greater than or equal to carbamylcholine. Acetylcholine did not inhibit [3H]DHA binding, nor did isoproterenol or choline inhibit [3H]QNB binding. Effectiveness of drugs in stimulating cAMP or cGMP accumulation closely paralleled efficacy in competition for [3H]DHA or [3H]QNB sites.

Diabetic microangiopathy is characterized by abnormalities in platelet function and increased susceptibility to thrombus formation. The synthesis of excessive amounts of PGs and TXA2 by platelets obtained from diabetic patients is underlying alteration in platelet responsiveness seen in diabetes mellitus. An associated reduction in PGI2 by endothelial blood vessels results in further disruption of the homeostatic mechanism regulating the aggregatory process. However, PGI2 behaviour in different tissues, and in blood vessels of varied calibre is yet unclear. PGI2 synthesis is restored to normal on reduction of blood glucose levels. Restoration of the synthesis of both prostanoids and PGI2 to normal, might be achieved by using drugs that inhibit prostanoid and TXA2 formation as well as by controlling glucose blood levels.
