Td Tr Tr Td Erectile Dysfunction
1,318 words... The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernous during sexual stimulation. NO then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP), producing smooth muscle relaxation in the corpus cavernous and allowing inflow of blood. Sildenafil has no direct relaxant effect on isolated human corpus cavernous, but enhances the effect of nitric oxide (NO) by inhibiting phospho...

Ph Of 5 Sulphur Dioxide
1,087 wordsAcidity is measured using a pH scale, with the number 7 being neutral. A substance with a pH value of less than 7 is acidic, while one of a value greater than 7 is basic. A substance with a pH of 6 is 10 times more acidic than another with a pH of 7. Usually the pH of 5. 6 has been used as the baseline in identifying acid rain, although there has been much debate over the acceptance of this value. Interestingly enough, a pH of 5. 6 is the pH value of carbon dioxide in equilibrium with distilled ...

Clean Air Act H 2 O
1,801 wordsAcid rain is exactly what it suggests- rain that is acidic. The definition of 'acid rain' is rain with a pH of below 5. 6. Rain becomes acidic because of gases that dissolve in the rain. Approximately 70 % of acid rain is a result of dissolved sulfur dioxide (SO 2) which forms Sulfuric Acid. The remaining 30 % or so comes from various Nitrogen Oxides (mostly NO 2 and NO 3 which has collectedly adopted the mane Nox). There is also a small percentage of hydrochloric acid that makes up hydrochloric...

Lancaster Nitric Oxide, or NO, its chemical representation, was until recently not considered to be of any benefit to the life processes of animals, much less human beings. However, studies have proven that this simple compound had an abundance of uses in the body, ranging from the nervous system ...
