I-Histamine: ingabe yikhemikhali ecasula kakhulu emzimbeni?

[I-molecule ye-Histamine] “Bleh”

Yizinto izinto zokwaliwa ngumzimba ezenziwa ngazo. Imfiva ethimulisayo? Ukungezwani kokudla? Ukungezwani komzimba nesikhumba? I-Histamine ibamba iqhaza elikhulu kuzo zonke.

Futhi lezo zimo zidlala indima enkulu kithina. Ngo-2015, idatha ye-CDC ikhombise ukuthi abantu abadala abangaphezu kuka-8% base-US babene-hay fever. Ngaphezulu kwezingu-5% zezingane zase-US ezazinokungezwani komzimba nokudla. Futhi okungenani i-12% yazo zonke izingane zase-US zazinokungezwani komzimba nesikhumba!

Manje yini isivumelwano? Kungani sinamakhemikhali akhathazayo emzimbeni wethu?

Yebo, i-histamine imvamisa ingumngane wethu.

I-Histamine iyimolekyuli esayina, ethumela imiyalezo phakathi kwamaseli. Itshela amaseli esisu ukuthi enze isisu i-asidi. Futhi kusiza ubuchopho bethu ukuhlala buvukile. Kungenzeka ukuthi uyibonile le miphumela ikhonjiswa yimithi evimba i-histamine. Amanye ama-antihistamine angenza silele kanti amanye ama-antihistamine asetshenziselwa ukwelapha i-acid reflux.

I-Histamine nayo isebenza namasosha ethu omzimba.

Kuyasiza ukusivikela kubahlaseli bakwamanye amazwe. Lapho amasosha omzimba ethola umhlaseli, amangqamuzana omzimba abizwa ngama-B-cell enza ama-antibodies e-IgE. Ama-IgE anjengezimpawu "EZIFUNWAYO" ezisakazeka emzimbeni wonke, zitshele amanye amaseli omzimba mayelana nabahlaseli abathile okufanele bababheke.

Ekugcineni amaseli ama-mast nama-basophil athatha ama-IgE futhi abe namandla. Lapho behlangana nomhlaseli ohlosiwe… Bakhipha i-histamine namanye amakhemikhali okuvuvukala.

Imithambo yegazi iyavuza, ukuze amaseli amhlophe egazi nezinye izinto zokuzivikela zikwazi ukungena ngesinyenyela futhi zilwe nomhlaseli.

Izenzo ze-Histamine zikhulu kakhulu ekuvikeleni umzimba kuma-parasites.

Kepha ngokungezwani komzimba, amasosha omzimba asabela ngokweqile ezintweni ezingenabungozi, hhayi ama-parasites. Yilapho i-histamine iba yisitha sethu. Ama-allergen avamile afaka amakinati, impova, kanye nedander yezilwane.

Imikhumbi evuzayo ibangela ukudabuka emehlweni, isiminyaminya emakhaleni, nokuvuvukala ... empeleni noma kuphi. I-Histamine isebenza nezinzwa ukukhiqiza ukulunywa. Ezilwelwe komzimba kungadala ukuhlanza nokuhuda. Futhi iqinisa imisipha emaphashini, ikwenze kube nzima ukuphefumula.

Okukhathaza kakhulu kulapho i-histamine ibangela i-anaphylaxis, ukusabela okunzima okungabulala. Imigwaqo yomoya evuvukile ingavimbela ukuphefumula, futhi ukwehla ngokushesha kwengcindezi yegazi kungalambisa izitho zegazi elibalulekile.

Manje yini engenziwa nge-histamine?

Ama-antihistamine avimba amaseli ekuboneni i-histamine futhi angaphatha ukungezwani komzimba okuvamile. Imithi efana ne-steroids ingathulisa imiphumela yokuvuvukala komzimba. Futhi i-anaphylaxis idinga ukwelashwa ngokudutshulwa kwe-epinephrine, evula izindlela zomoya, futhi inyuse umfutho wegazi.

Ngakho-ke ubudlelwano bethu ne-histamine bu… buyinkimbinkimbi. Singenza kangcono.

I-NIH futhi ikakhulukazi iNational Institute of Allergy and Infectious Diseases (NIAID) isekela ucwaningo lwe-histamine nezimo ezihlobene nayo. Kunentuthuko enkulu ekuqondeni izimbangela zokungezwani komzimba nokulawula izimpawu zokungezwani komzimba, nokuthola ukuthi kungani i-histamine, i-frenemy yethu, isebenza ngendlela eyenza ngayo.

Thola ucwaningo oluthile olusesikhathini nezindaba ezivela ku-medlineplus.gov naku-NIH MedlinePlus umagazini, medlineplus.gov/magazine/, futhi ufunde kabanzi ngocwaningo lwe-NIAID ku- niaid.nih.gov.
