Thaum turbidity, hemorrhage, lwj tsis hnov tsw, lub qe no tej zaum yuav kis tus kab mob. Nws yuav tsum tau muab pov tseg, cov tais diav nchuav tshuaj ob txhais tes raws li lawv lis. Xab npum nyob rau hauv cov neeg mob tsis pab.

Lub caij ntuj no flash, siab lub neej no thiab hu rau-tsev neeg kis tau tus mob mechanism ntawm tshuaj tua kab mob kuj tshwm sim yog vim li cas thiab vim lub fact tias cov zaub mov kev ruaj ntseg yog Centralized.

ncu tus kab mob lub sij hawm

Lub ncu tus kab mob lub sij hawm kav los ntawm rau mus rau yim lub sij hawm ib hnub twg, tab sis ntau zaus tus thawj cov tsos mob tshwm sim tsis pub dhau thawj hnub los yog ob tug tom qab noj mov ib tug zaub mov thiab cov khoom.

Yog ib tug ua txhaum ntawm cov dej-ntsev metabolism vim zawv plab, quav yuav ua dej, frothy, tsw, nrog zaub ntsuab, reminiscent ntawm lub "hav iav av nkos" nrog ib zaus ntawm mus txog kaum lub sij hawm ib hnub twg, rau ib lub lim tiam los yog ntau tshaj.
