Preventing bacterial or viral infectivity and composition containing infection preventing additive

1. A method of prophylaxis against bacterial and/or viral infection in a mammal at risk for a bacterial or a viral infection, said method comprising administering to said mammal an infection development preventing or mitigating effective amount (or a dynamin activation preventing or inhibiting effective amount) of a nitric oxide synthesis inhibitor or a nitric oxide scavenger and discontinuing said administration within one month or within two days after infection is observed or determined in the mammal, whichever is shorter.

2. The method of claim 1 , where the mammal is at risk for development of bird flu infection and an infection preventing or mitigating amount of antibiotic nitric oxide synthesis inhibitor is what is administered.

3. The method of claim 2 where the antibiotic nitric oxide synthesis inhibitor administered is minocycline.

4. A method of prophylaxis of development in a mammal at risk for development of a cancer where overstimulation of a receptor, contributes to development of the cancer, comprising administering to said mammal a said receptor internalization inhibiting amount of a nitric oxide synthesis inhibitor or a nitric oxide scavenger and discontinuing administration within a month or within two days after said cancer is observed or determined in the mammal, whichever is shorter.

5. A method of preventing loss of beta agonist responsivity in a heart failure patient with compensated heart failure or in asthma patient with normal tone comprising administering to the heart failure patient or administering to the asthma patient between exacerbations a beta agonist desensitization preventing amount of a nitric oxide synthesis inhibitor or nitric oxide scavenger.

6. A method of prophylaxis against heart attack in a mammal with plaque accumulation, comprising administering an amount of anti-vascular endothelial growth factor receptor antibody effective to prevent destabilization of plaque and a vascular endothelial growth factor receptor internalization preventing or inhibiting effective amount of a nitric oxide synthesis inhibitor or a nitric oxide scavenger, and discontinuing administration of the nitric oxide synthesis inhibitor or nitric oxide scavenger within a month or if a heart attack occurs.

7. A spermicidal composition gel comprising a spermicidally effective amount of a spermicide and an infection preventing or inhibiting effective amount of an nitric oxide synthesis inhibitor or an nitric oxide scavenger.

8. A nasal composition for topical application for the prevention of development of infection and/or mitigation of the symptoms thereof, comprising a nasal congestion preventing or mitigating effective amount of a nasal steroid and an infection preventing or mitigating effective amount of an NO synthesis inhibitor or an NO scavenger.

9. A urinary tract infection prophylaxis composition comprising an infection preventing or infection mitigating effective amount of a non- antibiotic NO synthesis inhibitor or an NO scavenger and an antimicrobial effective of an antimicrobial and/or an antifungal effective amount of an antifungal.

10. A composition comprising an anti-EGER blocking effective amount of anti-EGER antibody and an EGFR blocking effective amount of an NO synthesis inhibitor or an NO scavenger.

11. Human blood component(s) composition for transfusion into a human in need thereof comprising whole blood, red blood cells, plasma, hemoglobin based blood substitute, albumin, platelets and/or white blood cells, and a dynamin blocking effective amount of an NO synthesis inhibitor or an NO scavenger.

12. A method for treating a mammal affected with a disorder treated by receptor blocking therapy comprising administering a receptor blocking effective amount of a receptor blocker and a receptor internalization preventing or inhibiting effective amount of a nitric oxide synthesis inhibitor or a nitric oxide scavenger so that receptors remain on cell surface to be exposed to the receptor blocking therapy.

13. A method for treating a mammal at risk for and later developing flu or bird flu, comprising administering to the mammal in accordance with the method of claim 1 and when infection develops administering an antiviral effective amount of oseltamivir phosphate.

14. The method of claim 4 where the receptor is EGFR.
