Perinatal hypoxia can lead to a number of serious medical conditions, such as Hypoxic Ischemic Encephalopathy (HIE) and brain injuries related to birth asphyxia. All three of these injuries are serious brain injuries that may lead to paralysis and severe brain damage.
1 A substance (or ligand) is cholinergic if it is capable of producing, altering, or releasing acetylcholine (indirect-acting) or mimicking its behaviour at one or more of the body's acetylcholine receptor types (direct-acting).2  Such mimics are called parasympathomimetic drugs or cholinomimetic drugs.n general, the word choline refers to the various quaternary ammonium salts containing the N,N,N-trimethylethanolammonium cation. Found in most animal tissues, choline is a primary component of the neurotransmitter acetylcholine and functions with inositol as a basic constituent of lecithin.
The term parasympatholytic typically refers to the effect of a drug, although some poisons act to block the parasympathetic nervous system as well. Most drugs with parasympatholytic properties are anticholinergics. Parasympatholytic and sympathomimetic agents have similar but not identical effects.
