Segmented neutrophils - basireletsi rona

Ka kakaretso, ho hlahloba mali a lokela balwa wbc, i.e. le peresente ya litlelase tse fapa-fapaneng tsa leukocytes ka mali. Boholo ba leukocytes ka batho ba baholo ka moralo di na le dipegelo neutrophils segmented (hoo e ka bang 70%). Ba - ba karolo e khōlō.

lisele tse tšoeu mali li arotsoe ka tse peli tse kholo letoto la lihlooho: granulocytes (granular) le agranulocytes (ka ho na lijo-thollo). Granulocytes, le eena, a arologanyediwa ka paka ya ka neutrophils, eosinophils le basophils. E mong le e mofuta oa li-cell o na le lijo-thollo tse itseng ka cytoplasm le nkang makgetheng ea eona e khethehileng.

lisele tsohle tsa granulocytic letoto la lihlooho tse ka ntshetsopeleng lona ka mekhahlelo ea ntshetsopele ya myeloblasts, ka letoto la lisele tse lipakeng immature ho hlaba le segmented leukocytes. Hona ho sebetsa ho mefuta eohle tse tharo tsa granulocytes - ho neutrophils, eosinophils le basophils. Ka mali pheriferale tloaelo fumanoe feela neutrophils la thipa le segmented. Lisele tse ka tlaase ka ba sebakeng mali ho tswa ho lesapo moko feela mafu matla.

Thipa neutrophiles sebopeho sa tšoaneng tsa khubu seleng. Ea mantlha ea pele e bataletseng, ka tsela e tšoanang ho wand kobehileng. Ea mantlha ea bobeli e arotsoe constrictions 'maloa e khethehileng (2-4) likarolo. The cytoplasm ea lisele penta pinki. Ho na le e ntle lijo-thollo e sootho. Ka mafu a tšoaetsanoang neutrophils graininess fetoha kholoanyane, 'me e putsoa (tse bitsoang toxigenic granularity). Sena ke e mong oa matšoao a khethollang ho ruruha.

Mosebetsi, e leng e phethile neutrophiles la thipa 'meleng e sirelelitsoe likaroloana tsoang linaheng tse ling, likokoana-hloko, li-fungus' me libaktheria li. Granulocytes na le mosebetsi phagocytic. granules tsena li na itseng potlakisang tsebetso ea lik'hemik'hale myeloperoxidase, ho kgothaletsa phello ea lintho tse antibacterial. Neutrophils ka susumelletsa mafolofolo a bua haholo ka ho ruruha.

Boleng segmented neutrophils le lisele tse ling tse ka leukocyte moralo tšoana ditlwaelo lilemo. Kahoo, ka bana ba ka tlaase lilemo tse 5 e le laoloa ke lymphocytes le neutrophils na ho feta 30%. palo ea sehlopha neutrophils ka tekanyo e tloaelehileng ho 1-6%. Keketseho ea palo ea neutrophils e tsamaea le mafu a sa tšoaneng 'me o bitsoa neutrophilia.

Ka tloaelo ho neutrophilia tsamaea palo yohle keketseho e leukocyte. Hangata ho neutrophils la thipa eketsehile haholo. Ka linako tse ling mali a ka mafu a matla hlaha immature lisele tse - metamyelocytes (mocha) le myelocytes. Eketseha palo ea lisele sehlopha, myelocytes le metamyelocytes ponahalo ea bitsoang battlefield ho le letšehali la leukocytes. battlefield moralo e atisa ho kopantswe le qaleha ea granularity toxigenic ho hlaba le segmented neutrophils le basophils cytoplasm bona.

liphetoho tse joalo felehetsa neutrophil hlobaetsang a hlabang lefu, e re tsitsipane, infarction, tse fapa-fapaneng intoxications. Haholo-holo a phatlalatsa battlefield ho le letšehali le le sa foleng myelocytic kankere ea mali. Ka lefu lena, segmented neutrophils le fokotseha sharply e le karolo e le ka ho ya ka ho feletseng. Ka moralo ho rena la thipa le lisele tse immature. Fokotsa palo ea neutrophils segmented isang 'nete ea hore ho sireletsa mosebetsi oa leukocytes decreases. Ho sokela go tlaleletsa ka tšoaetsoa mafu a sa tšoaneng.

Phokotso ea neutrophils segmented le sehlopha sa 'mino se bitsoang neutropenia. Hangata le hlaha ka semelo sa fokotseha kakaretso ka lisele tse tšoeu tsa mali. Joalo boemong ba ho le hlaha ka tšoaetsoa mafu a sa foleng 'me bongata ba kokwanahloko, hangata ka mor'a ho amohela cytostatics, ka mor'a phekolo mahlaseli, mafu a ea mali tse kang agranulocytosis le aplastic khaello ea mali.

Kahoo, karolo ea neutrophils segmented ke ho sireletsa motho tšoaetsong. Ka mafu a ea palo ea eketseha compensatory. Sena se bonahala ka phetoho karo-karolelano ea lisele tse ka moralo oa mali.
