Kodi tsitsi limakhala loyera lisanakhwime? Kupeza kwatsopano kokhudza maselo oyambira 'okhazikika'!

Mukayang'ana pagalasi mwadzidzidzi n’kuona tsitsi la imvi, mumamva mantha komanso chisoni pang’ono, sichoncho? Payenera kuti pamakhala nthawi zambiri pamene mumaganiza kuti, “Inenso ndakalamba tsopano.” Kwa anthu ena, tsitsi lawo limayamba kuoneka imvi ali aang’ono kwambiri, nthawi zina akadali kusukulu. N’chifukwa chiyani izi zimachitikadi? Kodi ndi chifukwa chakuti tikukalamba? Kafukufuku waposachedwapa wa zachipatala wapeza kuti izi zitha kukhala chifukwa cha kusintha pang’ono m’thupi lathu komwe palibe aliyense wa ife amene anaganizapo.

Kodi maselo odabwitsa awa omwe amapatsa tsitsi mtundu wake ndi ati?

Mwachidule, tsitsi lanu limakhala ndi mtundu wake wokongola wakuda ndi bulauni chifukwa cha mtundu wapadera wa selo pansi pa tsitsi lanu. Timatcha maselo oyambira a pigment awa, kapena kuti ``Melanocyte Stem Cells - McSCs``. Awa ndi gawo lalikulu la fakitale yathu yopangira utoto wa tsitsi.

Koma maselo oyambira awa sangasinthe mtundu wa tsitsi mwachindunji. Kuti achite zimenezo, choyamba ayenera kukula ndikukhala "melanocytes." Ma melanocyte awa ndi omwe amapanga utoto womwe umapatsa tsitsi mtundu wake.

Chifukwa chake tsitsi lanu limakhala lathanzi komanso lakuda ndichakuti maselo oyambira awa amakula pakapita nthawi, amakhala maselo a pigment, ndipo akugwira ntchito yawo moyenera. Chodabwitsa n'chakuti, maselo oyambira awa amakhala ndi moyo kwa zaka zambiri, koma amafa maselo ena omwe amapanga shaft ya tsitsi asanayambe. Mwina mwazindikira kuti anthu ena sataya tsitsi lawo akamakalamba, koma tsitsi lawo lasanduka loyera kwathunthu. Ichi ndichifukwa chake. Maselo a shaft ya tsitsi akugwirabe ntchito, koma maselo omwe amapanga shaft ya tsitsi asiya kugwira ntchito.

Kodi 'kukana' kumatanthauza chiyani? Zomwe zapezeka posachedwapa!

Kwa nthawi yayitali, madokotala ndi asayansi ankaganiza kuti maselo oyambira awa amakhala pamalo amodzi, akukhwima akafunika kutero, kenako n’kufa ntchito yawo ikatha. Koma kafukufuku waposachedwapa wasintha nkhaniyi kwathunthu.

Malinga ndi zomwe zapezeka zatsopanozi, maselowa amagwira ntchito mozungulira. Izi ndi izi:

1. Gawo loyamba: Amayamba ngati maselo oyambira osakhwima.

2. Ntchito: Kenako imapita ku gawo lina la tsitsi, imakhwima, ndikupanga utoto womwe umapatsa tsitsi mtundu wake.

3. Ulendo wobwerera: Ntchito ikatha, maselo amenewo amabwerera m'malo awo oyambirira, kutanthauza momwe maselo oyambira alili, ndipo amabwerera m'malo awo oyambirira.

Malinga ngati izi zikupitirira, tsitsi lathu lidzasintha mtundu.

Ndiye vuto lili kuti?

Ofufuza apeza kuti pamene tikukalamba, maselo ofunika awa nthawi zina amamatirira pamalo olakwika mu shaft ya tsitsi. Amamatirira mu gawo la shaft ya tsitsi lotchedwa follicle bulge. Akamatirira, sangathe kumalizanso kayendedwe kawo, zomwe zikutanthauza kuti sangathe kukula ndikupanga utoto.

Zotsatira zake? Tsitsi latsopano silikhala ndi mtundu uliwonse. Choncho limakhala loyera kapena la imvi.

Tiyeni tifotokoze pang'ono za njirayi.

Kodi izi zikuperekanso chithunzithunzi chokhudza khansa?

Inde. Kupeza kumeneku kungakhale kofunikira osati kokha pa imvi ya tsitsi, komanso kumvetsetsa khansa ya pakhungu . Makamaka, mtundu woopsa kwambiri wa khansa ya pakhungu , melanoma , umachokera ku maselo a pigment awa (melanocytes).

Chimodzi mwa zizindikiro zoopsa kwambiri za maselo a khansa ya melanoma ndi kuthekera kwawo kusintha mosavuta chibadwa chawo. Mu zamankhwala, izi zimatchedwa 'plasticity' . Luso limeneli ndi chifukwa chake khansa ya melanoma imakhala yovuta kuyilamulira komanso kuichiritsa kwathunthu.

Kafukufuku watsopanoyu akusonyeza kuti maselo athu abwinobwino komanso athanzi a pigment alinso ndi 'plasticity' yayikulu. Chifukwa chake, asayansi tsopano akukayikira kuti khalidwe loopsa la maselo a khansa ya melanoma mwina lidachitika chifukwa cha 'kutha kusintha' kwa maselo abwinobwino a pigment okha, komwe amachokera.

Ndiye kodi zingatheke kupeza mankhwala a izi?

Ili ndi funso lomwe aliyense ali nalo. Tsopano popeza njira 'yotsekeka' iyi yapezeka, cholinga chotsatira cha ofufuza ndikupeza njira yotulutsira maselo otsekeka awa ndikuwabwezera pamalo awo oyenera . Ngati zimenezo zingatheke, zitha kuletsa tsitsi kuti lisasinthe imvi, ndipo mwina zingachititse kuti tsitsi lisasinthenso kukhala lakuda.

Koma izi zikadali mu gawo lofufuza. Palibe mankhwala a izi pakadali pano. Komabe, pakhala malipoti akuti anthu ena omwe tsitsi lawo lakhalanso laimvi chifukwa cha mankhwala operekedwa ku matenda ena. Mwina mankhwala amenewo 'akumasula' maselo omwe agwidwa mwangozi.

Tiyeneranso kufufuza mozama ngati zinthu monga kupsinjika maganizo ndi kusuta fodya zimakhudza kutsekeka kwa maselo amenewa, chifukwa tikudziwa kuti zinthuzi zimakhudza kwambiri machitidwe ambiri m'thupi.
