Sympathomimetics stimulate lub plawv los ntawm activating beta-adrenergic receptors, thiab ua rau vascular du nqaij contraction thiab vasoconstriction los ntawm activating alpha-adrenergic receptors.
tshuaj sympathomimetic ua dab tsi?
Sympathomimetic tshuaj mimic lossis txhawb lub paj hlwb adrenergic, thiab lawv tuaj yeem ua rau ntshav siab nce siab, tshwj xeeb tshaj yog cov neeg mob ntshav siab.
Yuav ua li cas yog cov kev phiv rau sympathomimetics?
- Tremor (feem ntau cov kev mob tshwm sim), ntxhov siab., insomnia., diaphoresis.
- Hypotension. (vim peripheral. vasodilation.) thiab. reflex tachycardia.
- YMetabolic cuam tshuam: hyperglycemia., hypokalemia.
Yuav ua li cas enzyme metabolize cov tshuaj sympathomimetic?
inhibition ntawm norepinephrine metabolism tuaj yeem tsim cov teebmeem sympathomimetic. Norepinephrine feem ntau yog metabolized los ntawm enzyme monoamine oxidase, cov tshuaj monoamine oxidase inhibitor (MAOI) tuaj yeem ua rau muaj kev cuam tshuam zoo li no.
Dab tsi yog qhov txawv ntawm sympathomimetic thiab Sympatholytic tshuaj?
A tshuaj uas txhim kho adrenergic muaj nuj nqi yog lub npe hu ua sympathomimetic tshuaj, whereas tshuaj uas cuam tshuam adrenergic muaj nuj nqi yog ib tug sympatholytic tshuaj.

Vim li cas cov tshuaj hypotonic rau lub cev qhuav dej?
Hypotonic daws hydrate hlwb raws li dej txav los ntawm vascular chaw mus rau qhov chaw intracellular. Piv txwv ntawm thaum siv cov tshuaj hypotonic suav nrog rau kev kho mob hypertonic lub cev qhuav dej, los hloov cov kua dej hauv lub cev lub cev qhuav dej, thiab kom dilute concentrated (high-sodium) serum .
Lub cev hnyav li cas rau koj lub cev?
Cov txiaj ntsig ntawm kev nqa qhov hnyav suav nrog tsim cov leeg nqaij, hlawv lub cev rog, ntxiv dag zog rau koj cov pob txha thiab pob qij txha, txo kev raug mob, thiab txhim kho lub plawv. Txhawm rau nqa qhov hnyav kom nyab xeeb, nws yog ib qho tseem ceeb uas yuav tsum pib qeeb, siv sijhawm so, thiab siv daim ntawv kom raug .
Dab tsi yog lub cev lub cev uas ua haujlwm ntawm lub teeb liab?
A system tuaj yeem txhais tau tias yog lub cev khoom siv ua haujlwm ntawm lub teeb liab. Piv txwv li, ib qho amplifier yog siv los ua kom nrov nrov input signal amplitude. Nyob rau hauv cov ntaub ntawv no, lub amplifier ua ib co kev khiav hauj lwm (s) ntawm lub teeb liab, uas muaj cov nyhuv ntawm nce lub amplitude ntawm qhov xav tau cov ntaub ntawv-cov kabmob teeb liab .
Lub cev kub npaum li cas ua rau tib neeg lub cev tawg?
Thaum koj lub cev kub cev nce txog 40°C, koj lub cev pib ua tsis tiav, thiab tshwj tsis yog tias koj nkag mus rau hauv qhov txias dua tam sim ntawd, koj yuav tuag . Yuav kub npaum cas los rhuav tib neeg? Ntawm 118 degrees, tib neeg daim tawv nqaij tuaj yeem txhawb nqa qhov kub hnyiab thawj zaug;
Lub cev twg thiaj tsim kho lub cev hauv lub cev?
Yuav luag txhua lub cev yog tsim los ntawm kwv yees li 10 lub lis piam tom qab fertilization (uas sib npaug 12 lub lis piam ntawm cev xeeb tub). Cov kev zam yog lub hlwb thiab qaum qaum, uas txuas ntxiv tsim thiab txhim kho thaum cev xeeb tub .
