9. The method of claim 4 wherein adherence of leukocytes or platelets is inhibited.
10. The method of claim 4 wherein the form of hyaluronic acid is sodium hyaluronate.
11. The method of claim 4 wherein adherence of leukocytes or platelets is inhibited and wherein the form of hyaluronic acid is sodium hyaluronate.
12. The method of claim 5 wherein adherence of leukocytes or platelets is reduced.
13. The method of claim 5 wherein the form of hyaluronic acid is sodium hyaluronate.
14. The method of claim 5 wherein adherence of leukocytes or platelets is reduced and wherein the form of hyaluronic arid is sodium hyaluronate.
15. A method of inhibiting arterial restenosis comprising administering to a human a pharmaceutical composition comprising together with pharmaceutically acceptable diluents, adjuvants and/or carriers:
(1) a form of hyaluronic acid consisting of sodium hyaluronate, and
(2) an agent selected from the group consisting of a non-steroidal anti-inflammatory drug, a restenosis inhibiting drug, Vitamin C, a free radical scavenger, an anti-oxidant and combinations thereof such that arterial restenosis after balloon angioplasty in humans is inhibited.
16. A method of inhibiting or reducing the adherence of leukocytes, the method comprising administering a therapeutically effective non-toxic amount of a form of hyaluronic acid to a human in need thereof, wherein the form of hyaluronic acid is selected from the group consisting of hyaluronic acid, pharmaceutically acceptable salts thereof and combinations thereof, and wherein the molecular weight of the form of hyaluronic acid is greater than 150,000 daltons and less than 750,000 daltons.
17. A method of inhibiting or reducing the adherence of smooth muscle cells, the method comprising administering a therapeutically effective non-toxic amount of a form of hyaluronic acid to a human in need thereof, wherein the form of hyaluronic acid is selected from the group consisting of hyaluronic acid, pharmaceutically acceptable salts thereof and combinations thereof, and wherein the molecular weight of the form of hyaluronic acid is greater than 150,000 daltons and less than 750,000 daltons.
18. A pharmaceutical composition comprising together with pharmaceutically acceptable diluents, adjuvants and/or carriers:
