Vim li cas sunbathing ua teeb meem? Cov kws tshawb fawb tshiab yuav qhia peb li cas?
Tam sim no muaj tag nrho cov kab ntawm cov tshuaj tiv thaiv zoo uas daws qhov teeb meem ntawm qhov teeb meem ntawm UV rays ntawm daim tawv nqaij. Tab sis yuav ua li cas tiv thaiv qhov tshwm sim ntawm nws overheating? Nws paub tias nyob rau hauv lub hnub cov khaubncaws sab nraud povtseg ntawm daim tawv nqaij tuaj yeem kub txog +40 ° C. Ntxiv mus, nyob rau hauv lub xeev "overheated" no, lawv tseem nyob rau ntau teev txawm tias tom qab sunbathing. Vim li cas thermal stress thiaj txaus ntshai?
Dab tsi yog tawv thiab vim li cas peb xav tau
Los ntawm qhov kev xav ntawm biology, daim tawv nqaij yog cov ntaub so ntswg uas sib cais qhov chaw sab hauv ntawm tib neeg lub cev los ntawm sab nraud. Raws li qhov no, nws yog daim tawv nqaij, zoo li tsis muaj lwm cov ntaub so ntswg hauv peb lub cev, uas muaj kev cuam tshuam ntawm ib puag ncig. Cov xwm txheej ntawm cov teebmeem no txawv: txhua yam, tshuaj, kub, thiab lwm yam. Qhov ntawd yog, txhawm rau ua haujlwm raws li qhov cuam tshuam, daim tawv nqaij yuav tsum tau ua kom muaj zog, tshuaj lom neeg thiab thermally resistant, yuav tsum zoo tiv thaiv peb ntawm ultraviolet rays thiab pathogens ( Cov kab mob, kab mob)… Tau daws tag nrho cov teeb meem no, xwm tau tsim ib qho kev tsim qauv zoo nkauj heev.
Lub hauv paus ntawm peb cov tawv nqaij yog ib hom cell tshwj xeeb - keratinocytes. Lub neej voj voog ntawm cov hlwb no yog ib ntu ntawm kev hloov pauv ntawm cov cell nyob rau hauv cov nplai keratinized. Lawv tsim ib tug ntau-txheej, complex txheej txheem ntawm nruj nreem txuas hlwb - lub epithelium. Tus naj npawb ntawm cov khaubncaws sab nraud povtseg no txiav txim siab lub zog ntawm cov tawv nqaij. Cov txheej hauv qab yog cov hlwb tsis paub qab hau uas tag nrho cov hlwb saum cov txheej txheem hauv paus pib. Sab saum toj txheej ntawm daim tawv nqaij yog tsim los ntawm ntau txheej ntawm cov uas twb tsis muaj sia, keratinized hlwb. Nws yog lawv uas coj cov neeg kho tshuab, lub cev thiab tshuaj muaj zog, yog li tiv thaiv cov hlwb ntawm lawv.
Tiv thaiv kab mob tiv thaiv kab mob thiab qog
Txawm li cas los xij, tseem muaj ntau cov qhua tuaj noj mov hauv daim tawv nqaij. Piv txwv li, immunocytes. Lawv loj hlob thiab loj hlob hauv cov pob txha pob txha, thiab tom qab ntawd, taug kev los ntawm lub cev, lawv kuj nkag mus rau ntawm daim tawv nqaij. Ib puag ncig uas cov hlwb nyob ua ntej raug ntiab tawm mus rau hauv daim tawv nqaij yog tus yam ntxwv ntawm qhov kub thiab txias thiab tshuaj lom neeg muaj pes tsawg leeg. Ntawm no (hauv daim tawv nqaij) immunocytes raug yuam kom koom nrog cov tawv nqaij hlwb tag nrho cov "kev nyuaj siab" ntawm lub neej nyob rau hauv periphery. Thaum raug kub thiab tsis kub, hnub ci hluav taws xob, kev ua haujlwm ntawm cov hlwb no raug sim tiag.
Ntawm cov kab mob tiv thaiv kab mob ntawm daim tawv nqaij muaj ib yam tshwj xeeb ntawm cov hlwb - natural killer cells (NK cells). Lawv ua haujlwm tseem ceeb heev - lawv paub thiab tua cov kab mob uas kis tau thiab hloov pauv (mob) hlwb. Kev cuam tshuam hauv kev ua haujlwm ntawm cov hlwb no ua rau muaj qhov tshwm sim loj: rov ua dua ntawm herpes, daim tawv nqaij neoplasms (papillomas), thiab lwm yam. Nws tau pom tias txawm tias qhov kub thiab txias hloov pauv tuaj yeem cuam tshuam rau kev ua haujlwm ntawm NK hlwb ("cov tiv thaiv hlwb"). Ntau qhov kev tshawb fawb tau pom tias qhov kub nce mus rau +39 ° C rau lub sijhawm luv luv txo qis lub peev xwm ntawm NK hlwb kom paub txog thiab rhuav tshem cov phiaj hlwb.
Tias yog vim li cas nws yog ib qho nyuaj rau overestimate qhov muaj peev xwm ntawm kev tswj lub zog ntawm NK hlwb ntawm peb cov tawv nqaij, uas tam sim no thiab ces pom lawv tus kheej nyob rau hauv xws li mob.
Lub discovery ua nyob rau hauv St
Xyoo 2013, American journal International immunopharmacology tau piav qhia txog cov khoom ntawm Allostatin® peptide, nrhiav tau los ntawm ib pawg kws tshawb fawb los ntawm St. Petersburg State University. Allostatin® yog ib qho kev xaiv stimulator ntawm NK hlwb. Cov kws tshawb fawb tau pom tias nyob rau hauv lub xub ntiag ntawm Allostatin®, NK hlwb ntes thiab rhuav tshem 5 zaug ntau lub hom phiaj.
Yog li, Allostatin® tuaj yeem dhau los ua kev txhawb nqa loj rau NK hlwb hauv qab qhov kub thiab txias. Thawj cov khoom siv tshuaj pleev ib ce raws li Allostatin® yog hydrogel rau daim tawv nqaij thiab daim di ncauj - Allomedin®.
Niaj hnub no txoj hauv kev los tswj cov tawv nqaij noj qab haus huv muaj xws li ua raws li cov cai ntawm post-tanning. Nws yog ib qho kev xyaum siv cov tshuaj nplaum uas muaj vitamin E los kho cov tawv nqaij tom qab raug UV rays.
Txhawm rau txo qhov teeb meem ntawm qhov kub thiab txias ntawm daim tawv nqaij, suav nrog Allomedin® gel hauv koj li kev saib xyuas tom qab li niaj zaus. Cov gel yuav tsum tau siv tom qab da dej, rau thaj chaw ntawm daim tawv nqaij raug mob (ntau dhau) tshav ntuj. Nws tsis yog qhov nyuaj los txhais lawv: ua ntej, cov no yog ib txwm qhib qhov chaw ntawm lub cev (lub ntsej muag), thiab ntxiv rau, cov tawv nqaij no tseem "hlawv" txawm ob peb teev tom qab raug tshav ntuj. Cov peptide gel Allomedin® ua kom cov tawv nqaij txias sai sai, txo qhov mob thiab rov ua haujlwm ntawm "cov hlwb tiv thaiv" yam tsis muaj qhov seem. Nco ntsoov tias lub ntsej muag zoo nkauj yog qhov lav ntawm kev zoo nkauj thiab cov hluas rau xyoo tom ntej.
* Yog tias cov tsos mob ntawm tus kab mob herpes twb tshwm sim lawm, thov siv Allomedin® txhua zaus koj hnov tsw, khaus thiab kub.
