Qhov tseeb sympathomimetic kev ua (ISA) qhia txog ib pawg ntawm beta blockers uas muaj peev xwm txhawb nqa beta-adrenergic receptors (agonist effect) thiab tawm tsam cov teebmeem stimulating ntawm catecholamines (antagonist effect) hauv kev sib tw.
Ntawm no, tshuaj sympathomimetic ua dab tsi?
Sympathomimetics yog cov tshuaj uas ua raws lossis hloov kho cov kev ua ntawm endogenous catecholamines ntawm kev xav tau lub paj hlwb . Direct agonists ncaj qha qhib adrenergic receptors thaum tsis ncaj qha agonists txhim kho kev ua ntawm endogenous catecholamines.
Ib yam li ntawd, kev ua haujlwm ntawm beta blockers yog dab tsi? Beta-blockers , kuj hu ua beta -adrenergic blocking agents, yog cov tshuaj uas txo koj cov ntshav siab. Beta-blockers ua haujlwm los ntawm kev thaiv cov teebmeem ntawm cov tshuaj hormone epinephrine, tseem hu ua adrenaline. Beta-blockers ua rau koj lub plawv dhia qeeb qeeb thiab tsis muaj zog, uas txo cov ntshav siab.
Xav txog qhov no, cov beta blockers twg muaj qhov ua haujlwm sib thooj sib thooj?
Beta blockers xws li pindolol ( Visken ), penbutolol sulfate ( Levatol ), thiab acebutolol hydrochloride ( Sectral ) txawv ntawm lwm cov beta-blockers vim lawv muaj cov kev ua sympathomimetic intrinsic (ISA), uas txhais tau tias lawv ua raws li cov teebmeem ntawm epinephrine thiab norepinephrine thiab tuaj yeem ua rau muaj ntshav siab thiab
Puas yog beta blockers siv rau kev ntxhov siab?
Beta - thaiv ua haujlwm zoo tshaj plaws rau cov xwm txheej luv luv uas cuam tshuam nrog kev ntxhov siab , xws li kev phobias thiab theem ntshai los ntawm kev thaiv cov tsos mob ntawm lub cev kev ntxhov siab nrog rau lub plawv dhia ceev ceev, nruj hauv siab, lossis tawm hws. Cov beta - thaiv feem ntau tau sau tseg rau kev ntxhov siab xws li propranolol (Inderal) thiab atenolol (Tenormin).

Qhov sib txawv ntawm kev txhawb siab rau kev ua haujlwm thiab kev ntxub ntxaug kev ntxub ntxaug yog dab tsi?
Nco ntsoov tias kev txhawb nqa kev ua haujlwm sib txawv los ntawm kev sib cais kev ntxub ntxaug (Sd). Qhov kev ntxub ntxaug qhia tias muaj kev txhawb nqa ntxiv, thaum lub zog txhawb nqa kev hloov pauv kev ua haujlwm ntawm tus txhawb nqa
Dab tsi yog glycoprotein dab tsi yog ib qho ntawm kev siv glycoproteins?
Glycoproteins yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas nrog cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ua ke ntawm cov protein, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell
Dab tsi yog qhov kev nkag siab tsis tu ncua thiab dab tsi yog qhov loj me me qhov ntev xim tsis tu ncua zoo li qub)?
Kev nkag siab tsis tu ncua, tseem hu ua qhov tsis sib xws, lossis qhov tshwm sim tsis tu ncua, kev nyiam tsiaj thiab tib neeg kom pom cov khoom paub zoo li muaj tus qauv zoo, qhov loj me, xim, lossis qhov chaw tsis hais txog kev hloov pauv ntawm lub kaum sab xis ntawm kev xav, nrug deb, lossis teeb pom kev zoo
Kev tsis saib xyuas yog dab tsi thiab plaub theem hauv kev ua pov thawj qhov tsis saib xyuas yog dab tsi?
Kev tsis lees paub yuav tsum ua pov thawj plaub yam hauv tsev hais plaub: lub luag haujlwm, ua txhaum cai, ua rau raug mob, thiab puas tsuaj/raug mob. Feem ntau hais lus, thaum ib tus neeg ua qhov tsis saib xyuas thiab ua rau raug mob rau lwm tus neeg, raws li txoj cai lij choj ntawm 'kev tsis saib xyuas' tus neeg tsis saib xyuas yuav raug cai raws txoj cai rau qhov ua rau raug mob
Dab tsi yog Beta blockers muaj kev ua haujlwm ntawm lub cev sympathomimetic?
Qee cov beta blockers (piv txwv li oxprenolol, pindolol, penbutolol, labetalol thiab acebutolol) muaj cov kev ua sympathomimetic (ISA). Cov neeg ua haujlwm no muaj peev xwm ua rau qis qis agonist kev ua haujlwm ntawm β-adrenergic receptor thaum tib lub sijhawm ua tus receptor site antagonist
