Claims:	1. A method for treating a patient having a PDGF mediated disease or medical condition comprising administering to a patient in need thereof a pharmaceutically effective amount of a Complex comprised of a PDGF Nucleic Acid Ligand and a Non-Immunogenic, High Molecular Weight Compound or a Lipophilic Compound. 2. The method of claim 1 wherein said Complex further comprises a Linker between said Ligand and said Non-Immunogenic, High Molecular Weight Compound or Lipophilic Compound. 3. The method of claim 1 wherein said Ligand comprises a Linker. 4. The method of claim 1 wherein said Non-Immunogenic, High Molecular Weight Compound is a Polyalkylene Glycol. 5. The method of claim 4 wherein said Polyalkylene Glycol is polyethylene glycol. 6. The method of claim 5 wherein said polyethylene glycol has a molecular weight of about between 10-80 K. 7. The method of claim 5 wherein said polyethylene glycol has a molecular weight of about 20-45 K. 8. The method of claim 4 wherein said Complex has the structure ##STR3## 9. The method of claim 1 wherein said Lipophilic Compound is a glycerol lipid. 10. The method of claim 9 wherein said Complex is associated with a lipid construct. 11. A method of inhibiting PDGF mediated angiogenesis comprising: covalently linking a PDGF Nucleic Acid Ligand to a Non-Immunogenic, High Molecular Weight Compound or Lipophilic Compound to form a Complex; and administering said Complex to a patient having a disease or condition comprising PDGF mediated angiogenesis. 12. A method of inhibiting the growth of tumors comprising: covalently linking a PDGF Nucleic Acid Ligand to a Non-Immunogenic, High Molecular Weight Compound or Lipophilic Compound to form a Complex; and administering said Complex to a patient having a disease or condition comprising tumors expressing PDGF. 13. The method of claim 12 wherein said tumors or cells or tissues surrounding said tumors are expressing PDGF. 14. The method of claim 12 wherein said tumors or cells or tissues surrounding said tumors are expressing PDGF receptors. 15. A method of inhibiting fibrosis comprising: covalently linking a PDGF Nucleic Acid Ligand to a Non-Immunogenic, High Molecular Weight Compound or Lipophilic Compound to form a Complex; and administering said Complex to a patient having a disease or condition comprising fibrosis. 16. The method of claim 15 wherein said Complex further comprises a Linker between said Ligand and said Non-Immunogenic, High Molecular Weight Compound or Lipophilic Compound. 17. The method of claim 15 wherein said Ligand comprises a Linker. 18. The method of claim 15 wherein said fibrosis is kidney fibrosis. 19. The method of claim 15 wherein said fibrosis is lung fibrosis. 20. The method of claim 15 wherein said fibrosis is bone marrow fibrosis. 21. The method of claim 15 wherein said fibrosis is radiation treatment-associated fibrosis. 22. The method of claim 16 wherein said Non-Immunogenic, High Molecular Weight Compound is a polyalkylene glycol. 23. The method of claim 22 wherein said polyalkylene glycol is polyethylene glycol. 24. The method of claim 23 wherein said polyethylene glycol has a molecular weight of about between 10-80k. 25. The method of claim 23 wherein said polyethylene glycol has a molecular weight of about between 20-45k. 26. The method of claim 25 wherein said complex has the structure ##STR4## 27. A method of inhibiting restenosis comprising: covalently linking a PDGF Nucleic Acid Ligand to a Non-Immunogenic, High Molecular Weight Compound or Lipophilic Compound to form a Complex; and administering said Complex to a patient having a disease or condition comprising restenosis. 28. The method of claim 27 wherein said Complex further comprises a Linker between said Ligand and said Non-Immunogenic, High Molecular Weight Compound or Lipophilic Compound. 29. The method of claim 27 wherein said Ligand comprises a Linker. 30. The method of claim 27 wherein said Non-Immunogenic, High Molecular Weight Compound is a polyalkylene glycol. 31. The method of claim 30 wherein said polyalkylene glycol is polyethylene glycol. 32. The method of claim 31 wherein said polyethylene glycol has a molecular weight of about between 10-80k. 33. The method of claim 31 wherein said polyethylene glycol has a molecular weight of about between 20-45k. 34. The method of claim 33 wherein said complex has the structure ##STR5## 35. The method of claim 27 wherein said restenosis is in-stent restenosis. 36. The method of claim 27 wherein said restenosis is in a coronary artery. 37. The method of claim 27 wherein said restenosis is in a non-coronary vessel.
