Vinblastine yog nyob rau hauv ib chav kawm ntawm cov tshuaj hu ua vinca alkaloids vinca alkaloids Applications. Vinca alkaloids yog siv nyob rau hauv chemotherapy rau mob qog noj ntshav. Lawv yog ib chav kawm ntawm lub voj voog ntawm tes-cov tshuaj cytotoxic tshwj xeebuas ua haujlwm los ntawm inhibiting lub peev xwm ntawm cov qog nqaij hlav qog noj ntshav: Ua raws li tubulin, lawv tiv thaiv nws los ntawm kev tsim rau hauv microtubules, ib qho tseem ceeb ntawm cov cellular. kev faib. https://en.wikipedia.org › wiki › Vinca_alkaloid

. Nws ua haujlwm los ntawm kev qeeb lossis nres kev loj hlob ntawm cov qog nqaij hlav cancer hauv koj lub cev.
Vinblastine tua cov qog nqaij hlav cancer li cas?
Antimicrotubule cov neeg ua haujlwm (xws li vinblastine), inhibit microtubule cov qauv hauv lub cell. Microtubules yog ib feem ntawm lub xov tooj ntawm tes apparatus rau kev faib thiab replicating nws tus kheej. Inhibition ntawm cov qauv no thaum kawg ua rau cell tuag.
Yuav ua li cas rau cov qog nqaij hlav cancer thaum muab vinblastine?
Vinblastine ua haujlwm los ntawm txwv tsis pub cov qog nqaij hlav qog noj ntshav sib cais ua 2 lub hlwb tshiab. Yog li nws thaiv kev loj hlob ntawm tus mob qog noj ntshav.
Vinblastine siv li cas rau mob qog noj ntshav?
Vinblastine yog siv los kho mob qog noj ntshav. Nws ua haujlwm los ntawm kev qeeb lossis nres kev loj hlob ntawm cov qog nqaij hlav cancer.
Tus txheej txheem twg vinblastine cuam tshuam nrog thaum lub sijhawm cell mitosis?
Vinblastine kev kho mob ua rau M theem tshwj xeeb ntawm lub voj voog kaw los ntawm kev cuam tshuam microtubuleKev sib dhos thiab tsim kom zoo ntawm cov mitotic spindle thiab lub kinetochore, txhua qhov tsim nyog rau kev sib cais ntawm chromosomes thaum lub sij hawm anaphase ntawm mitosis.

Vim li cas cov qog nqaij hlav cancer txawv txav?
Cancer is tsis kuaj xyuas cell loj hlob. Kev hloov pauv hauv cov noob tuaj yeem ua rau mob qog noj ntshav los ntawm kev ua kom nrawm ntawm cell faib cov nqi lossis inhibiting ib txwm tswj ntawm lub cev, xws li cell voj voog ntes lossis programmed cell tuag.
Puas yog cov qog nqaij hlav cancer?
Tsis yog txhua tus qog nqaij hlav tsis zoo, lossis mob qog noj ntshav, thiab tsis yog txhua tus mob hnyav. Tsis muaj cov qog zoo li no. Cov kab mob sib hloov thiab ua haujlwm tsis zoo no tuaj yeem ua rau mob thiab ua kom tsis zoo, cuam tshuam rau lub cev thiab, muaj peev xwm, kis thoob plaws lub cev.
Puas mob qog noj ntshav axillary qog nqaij hlav mob?

Cov qog nqaij hlav loj no tuaj yeem ua rau tsis xis nyob. Yog tias koj pom muaj qhov txawv txav ntawm lossis ib puag ncig koj ob txhais caj npab lossis hauv siab, nrhiav kev kho mob tam sim.
Vim li cas cov qog nqaij hlav cancer tsis txawj tuag?
Nrog rau txhua lub cell faib, telomeres luv kom txog thaum lawv dhau los ua luv luv los tiv thaiv chromosomes thiab cell tuag. Mob qog noj ntshav ua tsis txawj tuag los ntawm kev thim rov qab cov txheej txheem telomere luv luv thiab hloov lawv cov telomeres ntev.
Puas hloov cov hlwb qog nqaij hlav cancer?
Cov hlwb tsis zoo lossis mob qog noj ntshav, loj hlob hauv vitro tau hloov pauv los ntawm lawv cov phenotype ib txwmvim kev hloov caj ces cuam tshuam rau cov proteins koom nrog hauv kev tswj lub voj voog ntawm tes. Keeb kwm, cov kev hloov pauv no tau coj mus rau kev txheeb xyuas cov noob thiab cov proteins tseem ceeb rau kev tsav lub voj voog ntawm tes mus tom ntej.
