Uma ubheka esibukweni bese ubona izinwele ezimbalwa ezimpunga ngokuzumayo, uzizwa ukhathazekile futhi udangele, akunjalo? Kumelwe ukuba kunezikhathi eziningi lapho ucabanga khona, "O, sengimdala manje." Kwabanye abantu, izinwele zabo ziqala ukuba mpunga besebancane kakhulu, ngezinye izikhathi besesesikoleni. Kungani lokhu kwenzeka ngempela? Ingabe kungenxa yokuthi siyaguga? Ucwaningo lwamuva lwezokwelapha luthole ukuthi lokhu kungaba ngenxa yoshintsho oluncane emzimbeni wethu okungekho noyedwa kithi oke walucabanga.
Yimaphi la maseli amahle anika izinwele umbala wazo?
Kalula nje, izinwele zakho zithola umbala wazo omuhle omnyama nonsundu ngenxa yohlobo olukhethekile lweseli phansi kwe-hair shaft yakho. Sibiza lawa maseli e-pigment stem , noma ngokunembile ``Melanocyte Stem Cells - McSCs``. Lawa yingxenye eyinhloko yefektri yethu yombala wezinwele.
Kodwa la maseli e-stem awakwazi ukufaka umbala ngqo ezinweleni. Ukuze enze lokho, kumele aqale avuthwe abe "ama-melanocyte." Lawa ma-melanocyte yiwo akhiqiza umbala onikeza izinwele umbala wazo.
Ngakho-ke isizathu sokuba izinwele zakho zibe nempilo futhi zibe mnyama ukuthi la maseli e-stem avuthiwe ngokuhamba kwesikhathi, aba amaseli e-pigment, futhi enza umsebenzi wawo kahle. Okumangazayo ukuthi la maseli e-pigment aphila iminyaka eminingi, kodwa ayafa ngaphambi kwamanye amaseli akha umphini wezinwele. Kungenzeka ukuthi uqaphele ukuthi abanye abantu abalahlekelwa izinwele zabo njengoba bekhula, kodwa izinwele zabo ziphenduke zaba mhlophe ngokuphelele. Nasi isizathu. Amaseli e-hair shaft asasebenza, kodwa amaseli akha umphini wezinwele ayeke ukusebenza.
Kusho ukuthini ukuthi 'ukunamathela'? Okutholwe muva nje!
Isikhathi eside, odokotela nososayensi babecabanga ukuthi la maseli e-stem ahlala endaweni eyodwa, avuthwa lapho kudingeka, bese efa lapho umsebenzi wawo usuqediwe. Kodwa ucwaningo lwakamuva luyishintshe ngokuphelele le ndaba.
Okwenzekayo empeleni kuyinto eyinkimbinkimbi kakhulu futhi emangalisayo. Lawa maseli afana ne-lizard eshintsha umbala. Okusho ukuthi, angahamba phakathi kwezingxenye ezahlukene zomucu wezinwele futhi ashintshe uhlobo lwawo, kunokuhlala endaweni eyodwa.
Ngokusho kwalokhu kutholakala okusha, la maseli asebenza ngemijikelezo. Okungukuthi:
1. Isigaba sokuqala: Ziqala njengamaseli okuqala angavuthiwe.
2. Umsebenzi: Bese iya kwenye ingxenye ye-hair shaft, ivuthwe, bese ikhiqiza imibala enikeza izinwele umbala wazo.
3. Uhambo lokubuya: Uma umsebenzi usuqediwe, lawo maseli abuyela esimweni sawo sokuqala, okungukuthi, esimweni samaseli okuqala , bese ebuyela endaweni yawo yokuqala.
Uma nje lo mjikelezo uqhubeka, izinwele zethu zizothola umbala.
Pho inkinga ikuphi?
Abacwaningi bathole ukuthi njengoba sikhula, la maseli ayigugu ngezinye izikhathi anamathela endaweni engafanele emgodleni wezinwele. Anamathela engxenyeni yomgodle wezinwele ebizwa ngokuthi i-follicle bulge. Uma enamathela, awakwazi ukuqeda umjikelezo wawo, okusho ukuthi awakwazi ukuvuthwa aye lapho kudingeka aye khona ukuze enze umbala.
Umphumela? Umugqa omusha wezinwele awutholi mbala. Ngakho-ke uphuma umhlophe noma umpunga.
Ake sichaze le nqubo kabanzi.
| Inqubo | Yini enye (kalula nje) |
|---|---|
| Izinwele ezincane ezinempilo | Ama-stem cell (ama-McSC) ahamba ngendlela efanele, avuthwe (abe ama-melanocyte), futhi anikeze izinwele umbala. Bese zibuyela esimweni sazo sokuqala. Lo mjikelezo uyaqhubeka. |
| Uma ukhula/lapho izinwele zakho ziphenduka zibe mhlophe | Amanye amaseli e-stem abambeka engxenyeni ye-hair shaft ebizwa ngokuthi 'i-bulge'. Awakwazi ukuqhubeka noma ukuvuthwa. |
| Umphumela wokugcina | Ngenxa yokuthi awekho amangqamuzana okukhiqiza umbala, izinwele ezisanda kukhula zimhlophe noma zimpunga. |
Ingabe lokhu kunikeza umbono ngomdlavuza?
Yebo. Lokhu kutholwa kungase kubaluleke hhayi nje kuphela ekushintsheni kwezinwele, kodwa futhi nasekuqondeni umdlavuza wesikhumba . Ikakhulukazi, uhlobo olubi kakhulu lomdlavuza wesikhumba , i-melanoma , luvela kula maseli e-pigment (ama-melanocyte).
Esinye sezici eziyingozi kakhulu zamaseli omdlavuza we-melanoma yikhono lawo lokushintsha kalula imvelo yawo. Kwezokwelapha, lokhu kubizwa ngokuthi 'i-plasticity' . Leli khono yingakho kunzima ukulawula umdlavuza we-melanoma nokwelapha ngokuphelele.
Lolu cwaningo olusha lubonisa ukuthi amangqamuzana ethu ombala ajwayelekile, anempilo nawo anezinga eliphezulu 'lokubumbana'. Ngakho-ke, ososayensi manje basola ukuthi lokhu kuziphatha okuyingozi kwamangqamuzana omdlavuza we-melanoma kungenzeka ukuthi kungenxa yaleli 'khono lokushintsha' kumaseli ombala ajwayelekile ngokwawo, lapho avela khona.
Ngakho-ke kuzokwenzeka yini ukuthola ikhambi lalokhu?
Lona umbuzo osengqondweni yawo wonke umuntu. Manje njengoba le nqubo 'ebambekile' isitholakele, umgomo olandelayo wabacwaningi ukuthola indlela yokukhulula la maseli abambekile bese ewabuyisela endaweni yawo efanele . Uma lokho kungenziwa, kungavimba izinwele ukuthi zingabi mpunga, futhi mhlawumbe kwenze kube nzima nokuguqula izinwele zibe mnyama futhi.
Kodwa lokhu kusesesigabeni socwaningo. Akukho ukwelashwa kwalokhu okwamanje. Kodwa-ke, kube nemibiko yabantu abathile abanezinwele ezimpunga eziphenduke zaba mpunga futhi ngenxa yemithi enikezwa ezinye izifo. Mhlawumbe leyo mithi 'iyakhulula' la maseli avalelekile ngengozi.
Sidinga futhi ukuphenya kabanzi ukuthi izinto ezifana nokucindezeleka nokubhema ziyakuthinta yini ukuvaleka kwala maseli, ngoba siyazi ukuthi lezi zinto zithinta kabi izinqubo eziningi emzimbeni.
Umlayezo Wokuya Nawe Ekhaya
- Isizathu esiyinhloko sokuba izinwele zakho zibe mhlophe ukuthi amaseli e-stem akhethekile anikeza umbala wezinwele, abizwa ngokuthi ama-Melanocyte Stem Cells, 'anamathele' endaweni engafanele emgodleni wezinwele.
- Lokhu kutholakale okusha kwesayensi. Abacwaningi bazama ukuthola ukwelashwa okungakhulula la maseli avalelekile futhi kuvimbele izinwele ukuba ziphenduke zibe mpunga.
- Okwamanje, akukho muthi othize ongavimba izinwele ukuthi zingabi mpunga. Qaphela ukuthi yini etholakala emakethe.
- Kuze kube yilapho kutholakala ukwelashwa okuqondile, ukwamukela imikhuba enempilo njengokudla ukudla okunempilo, ukugwema ukubhema, kanye nokulawula ukucindezeleka kuzosiza impilo yakho iyonke kanye nempilo yezinwele zakho.
- Uma ubona ushintsho olungazelelwe nolungajwayelekile esikhumbeni noma ezinweleni zakho (isib. amabala amasha, ukuba mpunga ngokushesha), ungesabi, kodwa qiniseka ukuthi ubona udokotela wakho ukuze akunike iseluleko.
