Noradrenaline (a.k. ua norepinephrine ) yog ib inotrope thiab muaj qhov zoo inotropic nyhuv nyob rau plawv cov leeg, thaum khi rau beta-1 adrenergic receptors ntawm cov ntaub so ntswg. Qhov tshwm sim yog kev tawm dag zog hauv lub plawv. NCO TSEG: Raws li tau hais yav dhau los hauv kab lus no, Inotrope Tsis zoo li Ionotrope.
Kuj paub, norepinephrine cuam tshuam rau lub plawv li cas?
Hauv lwm lub cev, norepinephrine nce plawv tus nqi thiab ntshav siab, ua rau tso tawm cov piam thaj los ntawm cov khw muag khoom hluav taws xob, ua kom cov ntshav ntws mus rau cov leeg pob txha, txo cov ntshav ntws mus rau lub plab zom mov, thiab inhibits ntuav ntawm lub zais zis thiab plab hnyuv motility.
Ib qho ntxiv, txhais li cas los ntawm ionotropic? Ionotropic tus txais: Ionotropic receptors yog membrane-bound receptor proteins uas teb rau ligand binding los ntawm qhib ib tug ion channel thiab tso cai rau ions ntws mus rau hauv lub cell, los yog nce los yog txo qhov yuav tshwm sim uas muaj peev xwm yuav tua.
Dhau li ntawm no, Dab tsi yog Chronotropic teebmeem ntawm acetylcholine ntawm lub plawv?
Chronotropic tshuaj tuaj yeem hloov pauv plawv tus nqi thiab kev sib dhos los ntawm kev cuam tshuam cov txheej txheem hluav taws xob ntawm lub plawv thiab cov hlab ntsha uas cuam tshuam rau nws, xws li los ntawm kev hloov cov atherosclerosis uas tsim los ntawm lub sinoatrial node. Zoo chronotropes nce plawv tus nqi; tsis zoo chronotropes txo plawv tus nqi.
Chronotropy thiab Inotropy yog dab tsi?
Cardioinhibitory tshuaj ua rau txo qis kev ua haujlwm ntawm lub plawv ( chronotropy ), myocardial contractility, inotropy ), los yog ob qho tib si, uas txo qis cov zis thiab cov hlab ntsha. Cov kev hloov hauv plawv no txo qis kev ua haujlwm ntawm lub plawv thiab myocardial oxygen noj.
