Lo lus zais cia yog hais txog kev tsim cov tshuaj los ntawm cov nqaij lossis qog.

Hauv tib neeg lub cev, lo lus no feem ntau yog siv los tham txog:

• bronchopulmonary tso zis
• qhov chaw mos ntswg
• zais plab
• salivary tso pa tawm

Lub sij hawm hnoos yog, hauv tshuaj, nyiam rau qhov tso zis thiab nws yog qhov tshwj xeeb. Los ntawm kev txhais, nws yog qhov ua kom khov, ua kom lub cev tso rau hauv tib neeg los ntawm ntau yam kabmob sab hauv lossis cov qog ua kua. Mucus ntau dua 95% dej, thiab nws tseem muaj cov protein ntau, tshwj xeeb yog mucins (2%), uas ua rau nws khov thiab tsis sib haum sib xws (zoo li qe dawb). Nws tseem muaj cov electrolytes, lipid, ntsev inorganic, thiab lwm yam.

Cov hnoos qeev tau tshwj xeeb los ntawm lub ntsws, tab sis kuj los ntawm cov txheej txheem zom zaub mov thiab kev ua me nyuam.

Cov hnoos qeev ua lub luag haujlwm ntawm lubrication, ua kom huab cua nyob hauv huab cua, thiab tiv thaiv, ua kom muaj kev tiv thaiv kab mob sib kis. Yog li ntawd nws yog qhov tso zis ib txwm muaj, qhov tseem ceeb rau kev ua haujlwm zoo ntawm lub cev.

Hauv daim ntawv no, peb yuav tsom mus rau cov pa hnoos qeev thiab hnoos qeev, uas yog “pom” tshaj plaws, tshwj xeeb tshaj yog cov kab mob ua pa.

Cov hnoos qeev yog qhov tseem ceeb los tiv thaiv cov hnoos qeev: nws yog thawj qhov "thaiv" tiv thaiv qhov khaus khaus thiab cov kab mob sib kis, uas txuas ntxiv nkag mus rau peb lub ntsws thaum muaj kev txhawb siab (ntawm tus nqi 500 L ntawm cov pa nqus ib teev, peb nkag siab tias muaj ntau yam "tsis huv" !). Nws yog zais los ntawm ob hom cell: epithelium (cov hlwb nto) thiab cov qog ua qog.

Txawm li cas los xij, thaum muaj tus kab mob los yog o tuaj, qhov tso zis ntau ntxiv tuaj. Nws kuj tseem tuaj yeem ua kom khov thiab thaiv txoj hlab pa, cuam tshuam nrog ua pa thiab ua rau hnoos. Kev hnoos tuaj yeem ua rau hnoos hnoos qeev. Cov hnoos qeev tau ua los ntawm cov hnoos qeev, tab sis kuj tseem tso tawm ntawm lub qhov ntswg, qhov ncauj thiab pharynx. Nws muaj cov khib nyiab ntawm tes thiab cov kab mob me me, uas tuaj yeem hloov nws qhov tsos thiab xim.

Nov yog qee qhov ua rau bronchial hypersecretion:

• mob ntsws
• kab mob ntsws thib ob (teeb meem ua npaws, khaub thuas)
• mob hawb pob (exaggerated bronchial secretion)
• pulmonary edema
• haus luam yeeb
• mob ntsws tav kev mob ntev los yog mob ntsws ua pa nyuaj
• sib cuag nrog cov pa phem (hmoov av, hmoov, tshuaj lom neeg, thiab lwm yam)
• cystic fibrosis (cystic fibrosis), uas yog kab mob caj ces
• idiopathic pulmonary fibrosis
• tuberculosis

Yog tias cov hnoos qeev tau tsim tawm ntau dhau, nws yuav cuam tshuam nrog kev sib pauv roj hauv lub ntsws (thiab yog li ua pa), tiv thaiv kev tshem tawm tsis zoo ntawm cov khoom tsis zoo thiab txhawb nqa cov kab mob colonization.

Kev hnoos feem ntau yuav pab tshem tawm cov hnoos qeev. Qhov hnoos yog qhov ua kom pom tseeb uas lub hom phiaj tshem tawm bronchi, lub ntsws thiab lub caj pas ntawm qhov tso zis uas ua rau nws qias neeg. Peb tham txog cov hnoos qeev lossis hnoos qeev thaum hnoos qeev tawm.

Thaum cov hnoos qeev muaj pus (daj lossis ntsuab), nws yuav tsim nyog tau sab laj, txawm hais tias xim tsis tas cuam tshuam nrog kev muaj cov kab mob. Ntawm qhov tod tes, muaj cov ntshav yuav tsum coj mus rau kev sab laj xwm txheej ceev.

Cov kev daws teeb meem nyob ntawm qhov ua rau.

Txog cov kab mob ntev xws li mob hawb pob, muaj kev kho kom zoo, muaj txiaj ntsig zoo thiab kho tus kab mob-kho kev kho mob uas pab tswj cov tsos mob thiab coj lub neej zoo li qub, lossis yuav luag.

Yog tias mob hnyav lossis mob hnyav, tshwj xeeb yog mob ntsws, yuav tsum tau kho tshuaj tua kab mob. Hauv qee kis, cov tshuaj txhawm rau txhawm rau tso zis kom yooj yim tshem tawm lawv tuaj yeem pom zoo.

Pom tseeb, yog tias qhov hnoos hawb pob tau cuam tshuam nrog kev haus luam yeeb, tsuas yog tso tseg kev haus luam yeeb yuav ua rau muaj kev kub ntxhov thiab rov ua rau lub ntsws zoo. Ditto yog tias qhov khaus cuam tshuam nrog kev kis kab mob, piv txwv li hauv chaw ua haujlwm. Hauv cov xwm txheej no, kws kho mob ua haujlwm yuav tsum tau sab laj los tshuaj xyuas qhov mob hnyav thiab yog tias tsim nyog, txiav txim siab hloov pauv txoj haujlwm.

Rau cov kab mob hnyav ntxiv xws li kab mob ua pa nyuaj lossis mob raum lossis cystic fibrosis, kev kho mob ntsws los ntawm pab pawg uas paub txog tus kabmob yuav pom tseeb.
