Lithethefatsi tsa adrenergic ke eng?
Lithethefatsi tsa adrenergic ke meriana e hlasimollang methapo e itseng 'meleng oa hau. Ba etsa sena ekaba ka ho etsisa ketso ea man messengersosa a lik'hemik'hale epinephrine le norepinephrine kapa ka ho susumetsa tokollo ea 'ona. Lithethefatsi tsena li sebelisoa maemong a mangata a sokelang bophelo, ho kenyeletsoa ho ts'oaroa ha pelo, ho ts'oha, ho hlaseloa ke asthma kapa ho itšoara hampe.
Ba sebetsa joang
Lithethefatsi tsa adrenergic li hlasimolla methapo tsamaisong ea methapo ea kutloelo-bohloko ea 'mele oa hau (SNS). Sistimi ena e thusa ho laola tsela eo 'mele oa hau o itšoarang ka eona ha o imetsoe kelellong kapa maemong a tšohanyetso. Nakong ea khatello ea maikutlo, SNS e ntša man messengersosa a lik'hemik'hale ho tsoa ho adrenal gland. Man messengersosa ana a lik'hemik'hale a sebetsa 'meleng oa hau ho eketsa ho otla ha pelo, ho fufuleloa, le ho hema le ho fokotsa ts'oaetso. Sena ka linako tse ling se bitsoa karabo ea "ntoa kapa sefofane".
Lithethefatsi tsa adrenergic li na le likarolo tse ts'oanang joalo ka man messengersosa a lik'hemik'hale ao 'mele oa hau o a hlahisang nakong ea khatello ea maikutlo, joalo ka epinephrine le norepinephrine. Libaka tse ling tse bitsoang li-adrenergic receptors li amohela melaetsa e tsoang ho epinephrine le norepinephrine e bolellang 'mele oa hau hore na o arabe joang. Lithethefatsi tsa adrenergic le tsona li sebelisana le li-receptor tsena. Ba ka etsisa epinephrine le norepinephrine mme ba tlama le li-receptor, ba baka ntoa kapa likarabo tsa sefofane. Lithethefatsi tsena li ka tlama le li-receptor ho matlafatsa tokollo ea epinephrine le norepinephrine.
Lithethefatsi tsa adrenergic li ka thusa ho etsa tse latelang:
- eketsa khatello ea mali
- thibile methapo ea mali
- bula litsela tsa moea tse lebisang matšoafong
- eketsa lebelo la pelo
- emisa ho tsoa mali
Mefuta ea lithethefatsi tsa adrenergic le ts'ebeliso ea tsona
Mofuta o mong le o mong oa lithethefatsi tsa adrenergic o sebetsana le maemo a fapaneng ho latela hore na ke li-receptor life tse reretsoeng. Ketso e ikhethileng ea moriana hape e latela hore na sethethefatsi se sebetsa ka kotloloho joalo ka len messengerosa la lik'hemik'hale kapa ka mokhoa o sa tobang ka ho hlohlelletsa tokollo ea man messengersosa a lik'hemik'hale.
Balateli ba likolobe
Lisebelisoa tsa bronchodilator li bula li-tubes tsa bronchial, kapa litemana tsa moea. Lithethefatsi tsena tsa adrenergic li sebetsa ka kotloloho ho li-beta receptors. Ha li tlama le li-receptor tsa beta-2, li etsa hore meea e tsamaisang matšoafo e bulehe. Sena se thusa ho ntlafatsa phefumoloho ho bakuli ba nang le mafu a phefumolohang a kang:
- asma
- lefu le sa foleng la pulmonary pulmonary (COPD)
- emphysema
- bronchitis
Mehlala ea li-bronchodilator e kenyelletsa:
- albuterol
- sebopeho
- levalbuterol
- kholofelo
- salmeterol
Vasopressor
Vasopressors ba ka sebetsa ho alpha-1, beta-1, le beta-2 adrenergic receptors. Le tsona li ka sebetsa ho li-receptor tsa dopamine. Lithethefatsi tsena li etsa hore mesifa e fokotsehe habonolo methapong ea mali. Sena se etsa hore methapo ea hau ea mali e be mosesane. Phello ena e boetse e etsa hore khatello ea mali ea hau e eketsehe.
Ho eketsa khatello ea mali ho ka thusa ho sebetsana le ts'oaetso. Ho fokotsa methapo ea mali ho ka thusa ho emisa ho tsoa mali. E ka thusa hape ho boloka li-anesthetics (lithethefatsi tse thethefatsang 'mele oa hau) ho hasana ka ho koala methapo ea mali e haufinyane.
Li-vasopressor tse ling li ka sebelisoa bakeng sa sefuba kapa ho kula. Li ka fokotsa methapo ea mali e ruruhileng ka har'a lera la nko. Lithethefatsi tsena hangata ho thoe ke li-decongestant tsa nko.
Mehlala ea li-vasopressor tse fapaneng e kenyelletsa:
- ephedrine
- epinephrine
- dopamine
- phenylephrine
- pseudoephedrine
- oxymetazoline
Li-stimulator tsa pelo
Li-stimulant tsa pelo li ka sebelisoa ho hlasimolla le ho khutlisa pelo e otlang. Li sebelisoa haeba pelo ea hao e khaotsa ho otla ka tšohanyetso ka lebaka la motlakase, ho bipetsana, kapa ho khangoa ke metsi. Ha sena se etsahala, epinephrine e ka kenoa ka kotloloho ka pelong ea hau ho thusa ho e qala ho otla hape.
Mehopolo e meng
Haeba u ntse u nahana ka sethethefatsi sa adrenergic, u lokela ho nahana ka litla-morao le nalane ea hau ea bongaka. Litla-morao tsa lithethefatsi tsa adrenergic lia fapana 'me li ipapisitse le sethethefatsi se khethehileng seo u se noang. Ha se batho bohle ba tla ba le litla-morao tse ka bang teng tsa sethethefatsi ka seng sa adrenergic. Ka mokhoa o ts'oanang, ha se lithethefatsi tsohle tsa adrenergic tse loketseng motho e mong le e mong. Maemo a bophelo bo botle ntle le seo o hlokang ho se phekola ka sethethefatsi sa adrenergic a ka bapala karolo ea ho etsa qeto ea hore na ke sethethefatsi sefe se u loketseng.
