2, to the influence of drug-induced depressive state
Chemical compounds such as reserpine mainly comprise through the symptomes complice that monoamine transmitters in the exhaustion brain brings out animal: body temperature decline, blepharoptosis and movable the inhibition.The generation of these symptoms possibly reduce monoamine transmitters in the brain with reserpine. 5-hydroxy tryptamine (5-HT) especially, and the result that supervention 5-HT receptor sensitivity changes.The monoamine transmitters system mainly comprises 5-HT system, NE system and dopamine (DA) system, in the pathogenesis of depression, plays an important role.5-HT in patients with depression brain and the cerebrospinal fluid, 5-HI-AA, the NE equal size is all low than the normal person.5-HT relates to the adjusting of emotion, sleep, vigilance, memory and appetite etc., and the NE deficiency then can cause spirit sluggish.Monoamine oxidase, MAO (MAO) is that (important inactivator DA) if this enzyme is suppressed, will make monoamine transmitters content increase in the brain to monoamine transmitters for 5-HT, NE, and this has positive effect to improving depression.In 1950's, people are when observing the curative effect of antihypertensive reserpine, and discovery has the patient of 10-15% to take this medicine for a long time approximately can produce depressive symptom.Pharmaceutical research afterwards shows; The basic pharmacological action of reserpine is the monoamine neurotransmitter of exhausting in the teleneuron vesicle; The monoamine hypothesis of depression has been proposed thus. think that it is the depressed mechanism that takes place that the synaptic space monoamine neurotransmitter reduces; And antidepressants reduce and the performance antidepressant effect mediator metabolism through blocking-up monoamine-reuptake or inhibition monoamine oxidase, MAO (MAO).
