The magnitude of the vasoplegic effect of vasoconstrictor agents, in decreasing order, was Adrenaline greater than KCl greater than 5HT, as shown in Figure-2-A and 2-B.
The current study, however, was conducted with adult quahogs, which are less vulnerable than larvae and juveniles to the effects of brown tide (Bricelj, 2009); and it was completed in July, when clearance by isolated quahog gills is less susceptible to the effects of both DA and 5HT (Gainey, 2007).
Calling a group of drugs specific serotonin reuptake inhibitors (SSRIs) is a bit of public relations: they have effects not only on all of the subtypes of 5HT receptors, but also on DA receptors (occasionally causing akathisia and tardive movement disorders) and GABA receptors (causing disinhibition), not just on the [5HT.
Besides 5HT reuptake inhibition, fluoxetine possesses some NE reuptake blockade and 5HT2c agonist action (20).
OBJECTIVES: We exposed neonatal rats to daily doses of diazinon or parathion on postnatal days (PND)1-4 and evaluated 5HT receptors and the 5HT transporter in brainstem and forebrain on PND5, focusing on doses of each agent below the maximum tolerated dose and spanning the threshold for cholinesterase inhibition: 0.

Los antidepresivos ejercerian sus efectos terapeuticos en la depresion y en los sindromes dolorosos actuando, segun algunos autores, sobre el sistema 5HT (28), mientras que para otros (29) la NA seria la diana fundamental para la accion sobre los sintomas dolorosos de los antidepresivos.

The process is believed to start when a chemical called serotonin,or 5HT,is released into the bloodstream from storage sites in the body, resulting in changes in the neurotransmitters and blood vessels in the brain.
We therefore aimed to evaluate AChE activities in the erythrocyte membranes from patients with PKU and to correlate the enzyme activities with blood concentrations of the biogenic amines A, NA, DA, and 5HT as well as with the precursors Tyr and Trp.
It is also possible the 5HT may be helpful for myoclonus that is caused by other factors.
