Kutentha kwa dzuwa ndi chitetezo chokwanira: zomwe zimachitika utagona pagombe
Zinthu zothandizira
N’chifukwa chiyani kuwotchedwa kwa dzuwa kwakhala kovulaza? Kodi asayansi atsopano atiuza chiyani?
Tsopano pali mizere yonse ya zoteteza zogwira mtima zomwe zimathetsa vuto la zowopsa za cheza cha UV pakhungu. Koma bwanji kupewa zotsatira zake kutenthedwa? Zimadziwika kuti padzuwa zigawo zapamwamba za khungu zimatha kutentha mpaka +40 ° C. Komanso, mu "kutentha" kumeneku, amapitirizabe kwa maola ambiri ngakhale atatha kuwotcha dzuwa. N'chifukwa chiyani kutentha kwa kutentha kuli koopsa?
Kodi chikopa ndi chiyani ndipo chifukwa chiyani tikuchifuna
Kuchokera pamalingaliro a biology, khungu ndi minofu yotchinga yomwe imalekanitsa malo amkati mwa thupi la munthu kuchokera kunja. Malingana ndi izi, ndi khungu, monga palibe minofu ina m'thupi lathu, yomwe imakhala ndi zotsatira za chilengedwe. Mkhalidwe wa zotsatirazi ndi wosiyana: makina, mankhwala, kutentha, etc. Ndiko kuti, kuti agwire ntchito ngati chotchinga, khungu liyenera kukhala lolimba pamakina, mankhwala ndi thermally kugonjetsedwa, liyenera kutiteteza bwino ku kuwala kwa ultraviolet ndi tizilombo toyambitsa matenda ( mavairasi, mabakiteriya) ... Atathetsa mavuto onsewa, chilengedwe chapanga zomveka ndi zokongola mapangidwe.
Maziko a khungu lathu ndi mtundu wapadera wa maselo - keratinocytes. Kuzungulira kwa moyo wa ma cellwa ndikutsatizana kwa masinthidwe kuchokera ku selo lamoyo kupita ku keratinized sikelo. Amapanga mawonekedwe amitundu yambiri, opangidwa movutikira a maselo olumikizidwa mwamphamvu - epithelium. Kuchuluka kwa zigawozi kumatsimikizira mphamvu zamakina zachikopa. Chosanjikiza chapansi ndi maselo osakhwima omwe maselo onse omwe ali pamwamba pa zigawo zapansi amachokera. Kumtunda kwa khungu kumapangidwa ndi zigawo zambiri za maselo opanda moyo, omwe ali ndi keratinized. Ndiwo omwe amatenga mphamvu zamakina, zakuthupi ndi zamankhwala, motero amateteza maselo amoyo kwa iwo.
Ma cell oteteza ku ma virus ndi zotupa
Komabe, pakhungu pali maselo ambiri a alendo. Mwachitsanzo, immunocytes. Amakula ndikukula m'mafupa, ndiyeno, akuyenda m'thupi, amalowanso pakhungu. Malo omwe maselowa amakhala asanatulutsidwe pakhungu amadziwika ndi kutentha kosalekeza ndi mankhwala. Pano (pakhungu) ma immunocytes amakakamizika kugawana ndi maselo a khungu "zovuta" zonse za moyo pamphepete. Mukakumana ndi kutentha kwakukulu ndi kotsika, kutentha kwa dzuwa, momwe ma cell amagwirira ntchito amayesedwa kwambiri.
Pakati pa maselo a chitetezo cha khungu pali mtundu wapadera wa maselo - maselo akupha (NK cells). Amagwira ntchito yofunika kwambiri - amazindikira ndikupha maselo omwe ali ndi kachilomboka komanso osinthika (chotupa). Kusokonezeka kwa ntchito yachibadwa ya maselowa kumabweretsa zotsatira zoopsa: kubwereranso kwa nsungu, ma neoplasms a khungu (papillomas), ndi zina zotero. Kafukufuku wambiri wasonyeza kuti kuwonjezeka kwakanthawi kochepa kwa kutentha kwa +39 ° C kumachepetsa kwambiri mphamvu ya maselo a NK kuzindikira ndi kuwononga maselo omwe akulimbana nawo.
Ichi ndichifukwa chake zimakhala zovuta kukulitsa kuthekera kosunga ntchito za NK maselo a khungu lathu, zomwe nthawi ndi nthawi zimapezeka m'mikhalidwe yotere.
Zomwe anapeza ku St
Mu 2013, magazini ya ku America International immunopharmacology inafotokoza za Allostatin® peptide, yomwe inapezedwa ndi gulu la asayansi ochokera ku St. Petersburg State University. Allostatin® ndi cholimbikitsa chosankha cha maselo a NK. Asayansi apeza kuti pamaso pa Allostatin®, ma cell a NK amazindikira ndikuwononga nthawi 5 ma cell omwe amatsata.
Choncho, Allostatin® ikhoza kukhala chithandizo chachikulu cha maselo a NK pakusintha kutentha. Chodzikongoletsera choyamba chochokera ku Allostatin® chinali hydrogel yosamalira khungu ndi milomo - Allomedin®.
Njira zamakono zosungira khungu lathanzi zikuphatikizapo kutsatira malamulo a pambuyo pochotsa khungu. Ndichizoloŵezi chofala kugwiritsa ntchito zonona zomwe zili ndi vitamini E kuti zibwezeretse khungu pambuyo pa cheza cha UV.
Kuti muchepetse zotsatira zoyipa za kutentha kwambiri pakhungu, phatikizani gel osakaniza a Allomedin® muzochita zanu zanthawi zonse zosamalira. Gelisi iyenera kugwiritsidwa ntchito mutatha kusamba, kumalo a khungu omwe ali ndi dzuwa kwambiri. Sikovuta kuwafotokozera: choyamba, awa nthawi zonse amakhala malo otseguka a thupi (nkhope), ndipo pambali pake, khungu loterolo likupitiriza "kuwotcha" ngakhale maola angapo atakhala padzuwa. Gel peptide Allomedin® imatsitsa khungu mwachangu, imachepetsa ululu ndikubwezeretsa ntchito ya "maselo oteteza" osasiya zotsalira. Kumbukirani kuti tani yoyenera ndi chitsimikizo cha kukongola ndi unyamata kwa zaka zambiri.
* Ngati zizindikiro za nsungu zaonekera kale, perekani Allomedin® nthawi iliyonse mukumva kumva kulasalasa, kuyabwa ndi kutentha.
