Segmented neutrophils - mu kare

A general, bincike na jini da ake bukata lasafta wbc, Ina nufin kashi na daban-daban azuzuwan na leukocytes a jini. Mafi yawa daga cikin leukocytes a cikin balagaggu a dabara dauki kashi segmented neutrophils (kamar 70%). Su ne - suna da babban kashi.

Farin jini Kwayoyin kasu kashi biyu manyan jerin: granulocytes (granular) da kuma agranulocytes (ba tare da wani hatsi). Granulocytes, bi da bi, suna subdivided cikin neutrophils, eosinophils da basophils. Kowane irin cell yana da wani takamaiman ƙwãya a cikin cytoplasm kuma daukawa da kansa musamman fasali.

All sel granulocytic jerin sabon ci gaba ta hanyar da matakai na raya kasa na myeloblasts, ta hanyar jerin matsakaici m Kwayoyin to soke da kuma segmented leukocytes. Wannan ya shafi dukan iri uku granulocytes - to neutrophils, eosinophils da basophils. A gefe jini kullum samu kawai neutrophils soka da segmented. A ƙaramin Kwayoyin suna located in jini daga bargo kawai a mai tsanani cututtuka.

Soka neutrophiles daban-daban siffar da cell tsakiya. A farko core ne lebur, kama da mai lankwasa Wand. Na biyu core ne zuwa kashi da dama musamman constrictions (2-4) segments. A cytoplasm na sel fentin ruwan hoda. Shi yana da lafiya hatsi ruwan kasa. A cututtuka neutrophils graininess zama ya fi girma, da kuma shudi (kira toxigenic granularity). Wannan shi ne daya daga cikin matakai ne na kumburi.

Aiki, wanda aka yi soka neutrophiles a cikin jiki ne kare daga kasashen waje barbashi, ƙwayoyin cuta, fungi da kwayoyin cuta. Granulocytes da phagocytic aiki. Wadannan granules dauke da takamaiman enzyme myeloperoxidase, shi kara habaka sakamakon antibacterial abubuwa. Neutrophils iya rayayye motsa a mayar da hankali na kumburi.

Darajar segmented neutrophils da sauran Kwayoyin a cikin leukocyte dabara yayi dace shekaru norms. Saboda haka, a cikin yara a karkashin 5 shekaru aka mamaye lymphocytes da kuma neutrophils da ba fiye da 30%. Yawan band neutrophils a al'ada yawa zuwa 1-6%. A karuwa a yawan neutrophils yana tare da cututtuka daban-daban da kuma ake kira neutrophilia.

Yawanci neutrophilia accompanies total karuwa leukocyte. Shi ne sau da yawa neutrophils soka ƙãra ma. Wani lokaci jini a cikin tsanani da cututtuka bayyana m Kwayoyin - metamyelocytes (matasa) da kuma myelocytes. Karuwan yawan band Kwayoyin, myelocytes da metamyelocytes bayyanar kira wani motsi zuwa hagu na leukocytes. shift dabara ne sau da yawa a hade tare da zuwan toxigenic granularity to soke da kuma segmented neutrophils da basophils su cytoplasm.

Irin wannan canje-canje bi neutrophil m kumburi cuta, bugu jihohi, infarction, daban-daban intoxications. Musamman furta miƙa zuwa hagu tare da kullum myelocytic cutar sankarar bargo. A wannan cuta, segmented neutrophils da kuma rage sharply a matsayin mai yawan da kuma a cikin cikakkar sharuddan. A dabara fi yawa soka kuma m Kwayoyin. Rage yawan segmented neutrophils take kaiwa zuwa gaskiya cewa m aiki na leukocytes rage-rage. Yana razana Bugu da kari na daban-daban cututtuka.

Akan rage segmented da band neutrophils aka kira neutropenia. Yana yakan auku a kan bango na janar karu a farin jini Kwayoyin. Irin wannan jiha faruwa a kullum, kuma kwayar cututtuka, sau da yawa bayan samun cytostatics, bayan radiation far, jini cututtuka irin agranulocytosis da aplastic anemia.

Saboda haka, rawar da segmented neutrophils ne don kare mutum daga kamuwa da cuta. A cututtuka na yawan compensatory ƙaruwa. Wannan aka nuna a cikin canji rabo na sel a cikin dabara na jini.
