The effect of L-arginine and NG-monomethyl-arginine on the response of the rat anococcygeus muscle to NANC nerve stimulation.
Ever since William Harvey described the circulation of
the blood, physiologists have realized that in sound
and living vessels the blood remains fluid, but it
coagulate in dead ones, (Ernst Bruke, 1857).
Endothelium-derived relaxing factors• The vasoactivity of ACh had been an enigma for many years.
• In 1914, Dale found it to be vasodilator.
• In 1915, Hunt said it was vasoconstrictor.
• In 1951, Burn and his collegues found that it was vasodilator and
vasoconstrictor.
• In 1980, Furchgott and Zawadzki showed that the endothelial lining was
essential for the vasodilator action of ACh (Endothelium-dependent ACh-
induced relaxation).
The endothelial cell as a metabolic and endocrine organ.
• For decades, we have been discovering hormones and
meditiators based on complex organic molecules such as
peptides, amines, PGs and LTs.
• in 1987, it turns out that one of the most fascinating of them
all is a simple one-to-one combination of the main element of
the atmosphere.
• Pharmacology and Physiology (biological sciences) are full of
surprises.
