Epidermal Fircyramil ndi kusintha kwa biochemial kwa khungu

Kagayidwe kake kameneka ndi kuti basal quratinocytes pang'onopang'ono amasunthira mtsogolo ndi kusiyanitsa kwa cell, ndipo pambuyo pake amafa kuti apange chivwende chosanjikiza, kenako nkugwa. Nthawi zambiri zimakhulupirira kuti ndi kuchuluka kwa zaka, choyambira chosanjikiza ndipo cholumikizira chimasokonekera, cholumikizira cha epidermis ndi dermis zimakhala lathyathyathya, ndipo makulidwe amachepetsa. Monga chotchinga cha thupi la munthu, Epirmis ikukhudzana mwachindunji ndi malo akunja ndipo amakhudzidwa mosavuta ndi zinthu zakunja zakunja. Chiwonetsero cha Epidermal chimawonetsa mosavuta kukopa kwa zaka komanso zinthu zakunja paukalamba kwa anthu.

Mu Epirmis wa chikopa cha chikopa, kusiyanasiyana kwa kukula kwake, morphology ndi mawonekedwe otsetsereka pang'onopang'ono, msomali wa khungu amakhala wofewa, ndipo makulidwe amachepetsa. Epirmal makulidwe amatsika ndi pafupifupi 6.4% pazaka khumi, ndipo amachepetsa ngakhale mwachangu mwa akazi. Epidermal makulidwe amatsika ndi zaka. Kusintha kumeneku kumatchulidwa kwambiri kumadera omwe akuwonetsedwa, kuphatikizapo malo owonjezera pamaso, khosi, manja, ndi mikono. Keratinocytes imasintha mawonekedwe ngati mibadwo yaying'ono ya khungu, ndikukhala lalifupi, pomwe nthawi yayitali, nthawi yochulukirapo imakhala yokulirapo, nthawi yopambana ya maselo a Epidermal imakhala yocheperako. Woonda, kupangitsa khungu kuti lisataye bwino komanso makwinya.

Chifukwa cha kusintha kumeneku morphological, ma epidermis-dermis kumverera silimba komanso osatetezeka pakuwonongeka kwa mphamvu yakunja. Chiwerengero cha Melanocytes pang'onopang'ono chimachepa pambuyo pa zaka 30, zowonjezera kuchuluka kwa Melanocytes zimachepa pamlingo wa 8% -20% pazaka khumi. Ngakhale khungu silovuta ku Tan, Melaocyte amasangalala kwambiri kupanga mawanga, makamaka m'malo owonekera dzuwa. Maselo a Lambrehans amachepetsedwa, ndikupangitsa kugwiritsa ntchito chitetezo cha pakhungu ndikugonjera matenda opatsirana.

Khungu AnyozerMakina angagwiritsidwe ntchito kuwuluka kwa khungu, mawonekedwe, kuwonongeka kwa contragen, ndipo nkhope ya nkhope kuti ithandizire kuzindikira kukalamba pakhungu.
