Segmented neutrophils - nevanozvitsigira dzedu

Kazhinji, Kuongororwa kweropa waida dzaona wbc, i.e. ari chikamu nemakirasi siyana pakati leukocytes muropa. Vazhinji leukocytes ari mukuru mu nzira vanoumba segmented neutrophils (vanenge 70%). Ndivo - ndivo mukuru chikamu.

masero eropa machena huviri makuru dzinoti: granulocytes (granular) uye agranulocytes (pasina nezviyo). Granulocytes, akavapindurawo, vari rakamuka-kamuka neutrophils, eosinophils uye basophils. Sero rimwe nerimwe rine chairo zviyo cytoplasm uye anoita yayo inokosha zvinhu.

Masero ose granulocytic dziri kwayo kukura kuburikidza nzendo kukura myeloblasts, kuburikidza akatevedzana zvenguva saibva masero kubaya uye segmented leukocytes. Izvi zvinoshanda zvose zvitatu mhando granulocytes - kuti neutrophils, eosinophils uye basophils. In peripheral ropa anowanzoitwa kuwanikwa chete neutrophils uchibaya uye segmented. Masero vaduku vari riri ropa kubva mwongo chete nehosha dzakaipa.

Uchibaya neutrophiles yakasiyana Maumbirwe muchitokisi musimboti. Chokutanga Musimboti yakati sandara, rakafanana curved seinään. Chechipiri chinoumba rakakamurwa kuva anokosha constrictions akawanda (2-4) zvikamu. The cytoplasm masero akapendwa Pink. It ane yakanaka tsanga mashava. In zvirwere neutrophils graininess kunova makuru, uye zvitema (ainzi toxigenic granularity). Uyu ndiwo mumwe zviratidzo chokutsva.

Basa, izvo akaita uchibaya neutrophiles mumuviri kunodzivirirwa kubva kune dzimwe nezvimedu, nemavhairasi, notumwe uye utachiona. Granulocytes vane phagocytic basa. granules izvi zvine dzakananga enzayemu myeloperoxidase, izvozvo runogonesa migumisiro antibacterial zvinhu. Neutrophils anogona kushingaira kufamba ari kutaurwa chokutsva.

Kukosha segmented neutrophils uye mamwe masero ari leukocyte payakavakirwa anoenderana nezera dzemunharaunda. Saka, vana pasi 5 makore hunodzorwa lymphocytes uye neutrophils hatina zvinopfuura 30%. Kuwanda bhendi neutrophils chaiye mari kuti 1-6%. Kuwedzera kwenhamba neutrophils achabatsirwa zvirwere zvakasiyana-siyana uye inonzi neutrophilia.

Yemanyorero neutrophilia kuita zvachose kuwedzera leukocyte. Kazhinji neutrophils uchibaya yakawedzera zvakare. Dzimwe nguva ropa nehosha dzakaipa kuonekwa masero saibva - metamyelocytes (vaduku) uye myelocytes. Kuwanda bhendi masero ikawanda, myelocytes uye metamyelocytes nechitarisiko akadana iya kuti rworuboshwe leukocytes. kusuduruka fomura rinowanzoshandiswa pamwe veMubatanidzwa toxigenic granularity kubaya uye segmented neutrophils uye basophils cytoplasm yavo.

Kuchinja kwakadaro pamwe neutrophil chakasimba anogumbura chirwere, kuvhunduka rinoti, infarction, siyana intoxications. Kunyanya kutaurwa iya kuti kuruboshwe pamwe chirwere myelocytic neleukemia. In chirwere ichi, segmented neutrophils uye kuderera zvikuru ari chikamu uye Mhedziso nemashoko. In fomura vakawanda uchibaya uye masero saibva. Kuderedza uwandu segmented neutrophils kunotungamirira kuti runodzivirira mashandiro leukocytes kunoderedza. It vanotyisidzira kuwedzera zvirwere zvakasiyana-siyana.

Kuderera kwemitambo segmented uye bhendi neutrophils anonzi neutropenia. Kazhinji kunoitika pazuva pakanyorwa vakawanda kuderera muropa mumasero machena. mamiriro akadaro kunoitika muna chirwere uye kutapukirwa noutachiona, kazhinji pashure kugamuchira cytostatics, pashure nemwaranzi kurapa, zvirwere ropa zvakadai agranulocytosis uye aplastic kupererwa neropa.

Saka, basa segmented neutrophils ndiko kudzivirira munhu kubva chirwere. In zvirwere nhamba compensatory kunowedzera. Izvi zvinoratidzwa nokuchinja reshiyo masero ari nzira ropa.
