Heparin, a highly sulfated glycosaminoglycan, has been widely used as an injectable anticoagulant. Heparin is present only in a few tissues and species of the animal kingdom and in the form of granules inside organelles in the cytoplasm of special cells. Heparin might be involved in defense mechanisms against bacteria and other foreign materials .
In vitro: Heparin (25-500 Nμ/ml) dose-dependently inhibited cellular aggregation and degranulation induced either by FMLP or by zymosan-activated serum. Heparin at the concentration of25 μg/ml specifically inhibited FMLP-dependent superoxide anion generation and chemiluminescence. Heparin inhibited all the aspects of the functional and metabolic granulocyte activation .
In vivo: In the cells from heparin-treated rats or in the heparin-treated cells, specific binding of [125I]iodo-angiotensin II was decreased due to a decrease in both the number and the affinity of angiotensin II receptors. Heparin also decreased the maximum angiotensin Il-induced productionof aldosterone in the cells from heparin-treated rats and in the heparin-treated cells. Heparin interacted with adrenal angiotensin II receptors to inhibit the angiotensin Il-induced aldosterone production .
