Kodi PDRN ndi chiyani kwenikweni? Kodi nchifukwa ninji akuyamikiridwa monga “chinsinsi chamankhwala ochiritsira kubadwanso kwatsopano”? 

M'madera a skincare ndi mankhwala okongoletsera, "kubadwanso" ndi lingaliro lochititsa chidwi. Khungu likawonongeka kapena kukalamba, timayembekeza nthawi zonse kudzutsa luso lake lokonzanso zachilengedwe. PDRN ndiye "kiyi" yomwe asayansi apeza posachedwa kuti ayambitse njira zokonzetsera ma cell. Lero, tiwulula zinsinsi zake.

Chiyambi: Kudzoza kuchokera ku mphamvu yobwezeretsanso ya nyanja

PDRN (Polydeoxyribonucleotide), yemwe dzina lake lonse ndi polydeoxyribonucleotide, si mankhwala opangidwa ndi mankhwala, koma m'malo mwake amachokera ku maselo achilengedwe obereketsa nsomba.

Asayansi adapeza kuti nsomba za salimoni zili ndi mphamvu zobwezeretsanso minofu ndikukonzanso. Kupyolera mu kafukufuku wowonjezereka, adatulutsa chidutswa cha DNA-PDRN-kuchokera ku umuna wa salimoni. DNA iyi ndi yofanana kwambiri pamapangidwe apakati ku DNA ya nyama zonse zoyamwitsa (kuphatikiza anthu), kuwonetsa biocompatibility yabwino kwambiri komanso chiopsezo chochepa cha kukana chitetezo chamthupi, motero kulola kuti igwiritsidwe ntchito bwino m'thupi la munthu.

Zofunika: Si "zinthu zopangira," komanso "chizindikiro."

Titha kumvetsetsa momwe PDRN imagwirira ntchito kuchokera pamalingaliro awiri oyambira:

Monga "zokonzera": PDRN imapangidwa ndi ma deoxyribonucleotides ambiri (mayunitsi oyambira a DNA). Minofu yapakhungu ikawonongeka ndipo maselo amafunika kugawikana ndikuchulukana kuti akonzenso, ma nucleotide omwe amapezeka mosavuta amatha kugwiritsidwa ntchito mwachindunji ndi maselo ngati zida zopangira DNA yatsopano, motero kufulumizitsa kukonzanso.

Monga "chizindikiro chokonzekera": Iyi ndi njira yofunikira komanso yapadera yochitira PDRN. PDRN ikhoza kudziwika mwachindunji ndi maselo ozungulira owonongeka kapena a hypoxic minofu ndikumangiriza ku adenosine A2A receptors pa selo pamwamba, kuletsa NF-kB ndi MAPK njira zowonetsera zomwe zimayendetsedwa ndi ROS.  Izi zimachepetsa kupanga ma pro-inflammatory cytokines (IL-6, IL-1β, TNF-α, etc.) ndipo zimalimbikitsa kufotokoza kwa anti-inflammatory cytokines (IL-10), motero zimakhala ndi mphamvu yotsutsa-kutupa.  Kuphatikiza apo, imathandizira katulutsidwe ka EGF (epidermal growth factor), FGF (fibroblast growth factor), VEGF (vascular endothelial growth factor), ndi angiopoietin, zomwe zimapatsa PDRN zabwino kwambiri zotsutsana ndi zotupa komanso machiritso a mabala.

Ntchito yayikulu: tcheni chokonzekera kuchokera ku micro kupita ku macro level.

Kutengera njira zomwe tafotokozazi, PDRN imakhala ndi zotsatira zabwino zolumikizana pakhungu:

Kumalimbikitsa angiogenesis: Kumawonjezera magazi kumalo owonongeka, kubweretsa mpweya wochuluka ndi zakudya komanso kuchotsa zinyalala za metabolism.

Imalimbikitsa kuchulukana kwa ma cell ndi kusamuka: Imathandizira ntchito ndi kuchuluka kwa maselo ofunikira okonza monga fibroblasts ndi keratinocytes.

Imalimbikitsa kaphatikizidwe wa collagen ndi elastin: Kulimbitsa khungu kuchokera ku dermis, kuwongolera mizere yabwino ndikuwonjezera kukhazikika.

Mphamvu yotsutsa-kutupa: Imachepetsa bwino zotupa monga kufiira, kutupa, kutentha, ndi kupweteka poyang'anira zinthu zotupa.

Kukonza minofu ndi kuchira kwa zilonda:  Kuphatikiza zonse zomwe zili pamwambazi, kumathandizira kwambiri kuchira kwa mabala osiyanasiyana.

PDRN imatchedwa "chinsinsi cha kusinthika" chifukwa sichimangokonza ndi kudyetsa, koma imayang'anira bwino ntchito ya maselo.  Kutengera biocompatibility yake yayikulu, imapangitsa kuti khungu lizitha kusinthika kudzera munjira zambiri zama synergistic. Njira iyi ya "kudzutsa kukonzanso kwamkati" ndizomwe zimafunikira pakukonzanso, ndipo ndizomwe zimapatsa PDRN malo ake osasinthika pankhani ya thanzi la khungu.
