Hello readers ,Here is something new information about human saliva !.
Human saliva and pain killer :-
Human saliva contains a painkiller that is naturally produced by human body .It is called as -"Opiorphin" in very low concentration.
Opiorphin's role:-
Opiorphin prevents the breakdown of chemicals called as enkephalins . Apart from this opiorphin inhibits 3 protease.-
a)Ecto-endo peptidase.
b)Ecto-amino peptidase .
c)Dipeptidyl peptidase.
This extends the duration of enkephalins.
The enkephalins activates opiate receptors .Activated opiate receptors blocks pain signals from reaching brain!!. opiorphin is 6 times more potent than morphine .Unlike morphine opiorphin is not addictive and prolonged use may not lead to tolerance .
Current status in research:
Painkiller was successfully tested on rats.Further research is still needed before it's use on humans .Research include modifying molecular structure to avoid rapid degeneration in intestine and it's poor BBB(Blood brain barrier !).Modification includes transformation of N-terminal glutamine into pyroglutamate .
