ANP yog synthesized thiab secreted los ntawm cov leeg mob plawv nyob rau hauv cov phab ntsa ntawm lub atria nyob rau hauv lub plawv. Cov hlwb no muaj qhov ntim cov receptors uas teb rau kev nthuav dav ntawm phab ntsa atrial vim muaj cov ntshav atrial nce ntxiv.
Atrial natriuretic peptide tuaj qhov twg?
Piv txwv li, atrial natriuretic peptide (ANP) yog peptide me me zais los ntawm lub plawv thaum atrial stretch thiab siab cov ntshav siab. Cov teebmeem ntawm qhov muaj zog no, lub neej luv luv peptide suav nrog nce glomerular pom thiab nce lub raum tso tawm ntawm sodium thiab dej.
Dab tsi ua rau atrial natriuretic hormone?
Atrial natriuretic factor (ANF) yog 28 amino acid polypeptide hormone secreted feem ntau yog los ntawm lub plawv atria teb rau atrial stretch.
ANP thiab BNP tuaj qhov twg?
Atrial natriuretic peptide (ANP) thiab B-type natriuretic peptide (BNP) yog zais los ntawm lub plawv atria thiab ventricles, raws li. ANP qhia hauv endocrine thiab paracrine yam kom txo cov ntshav siab thiab plawv hypertrophy. BNP ua haujlwm hauv zos kom txo qis ventricular fibrosis.
Puas BNP nce ntshav siab?
Abstract-Increased hlwb natriuretic peptide (BNP) qhia nyob rau hauv lub ventricles antedates elevated ntshav siab(BP) hauv kev sim kev tshawb fawb. Peb xav tias cov ntshav BNP ntau dua hauv cov ntshav tsis muaj zogCov tib neeg tuaj yeem cuam tshuam nrog qhov muaj feem ntau ntawm yav tom ntej BP nce thiab / lossis kub siab.

Atrial fibrillation ua rau mob stroke li cas?
Nyob rau hauv atrial fibrillation, ntshav tuaj yeem tso rau hauv lub plawv sab sauv thiab tsim cov ntshav txhaws. Yog tias cov ntshav txhaws nyob rau sab laug sab laug sab sauv (sab laug atrium), nws tuaj yeem tawg tawm ntawm koj lub siab thiab mus rau koj lub hlwb.
Ntawm atrial natriuretic yam?
Atrial natriuretic factor (ANF) yog28 amino acid polypeptide hormone secreted feem ntau yog los ntawm lub plawv atria teb rau atrial stretch. ANF ua rau lub raum nce sodium excretion thiab GFR, los tiv thaiv lub raum vasoconstriction, thiab inhibit renin secretion.
Cov tshuaj peptide ua li cas?
Peptide cov tshuaj hormones tau zais thiab ua haujlwm hauv endocrine yam los tswj ntau lub cev lub cev, suav nrog kev loj hlob, qab los noj mov thiab lub zog metabolism, lub plawv ua haujlwm, kev ntxhov siab, thiab kev yug me nyuam physiology.
Atrial natriuretic hormone ua haujlwm li cas?
ANP stimulates vasodilation ntawm afferent arteriole ntawm glomerulus : qhov no ua rau kom cov ntshav ntws mus rau lub raum cov ntshav ntws hauv lub cev ntawm lub raum, lub raum ntshav ntws (RBF) yog qhov ntim ntawm cov ntshav xa mus rau ob lub raum ib lub sijhawm.
Thaum twg atrial natriuretic peptide tso tawm?
Atrial natriuretic peptide (ANP) yog ib yam tshuaj uas yog tsim los ntawm atrial myocytes thiab raug tso tawm teb rau qhov nce atrial distention. Dab tsi ua rau atrial natriuretic peptide tso tawm? ntim ntim, cov tshuaj vasoconstrictor, tso rau hauv dej, atrial tachycardia thiab cov khoom noj ntsev ntautau tshaj tawm tias yuav ua rau kom tso tawm ntawm lub plawv ANP, yog li qhia tias peptide raug tso tawm hauv teb rau qhov nce ntawm atrial siab.
