Q hoʻololi a me ka mīkini laser yag AMC8
Hoʻopuka ka ikehu Laser Q-switch i kekona kekona, e hana ana i ka mana kiʻekiʻe loa me ka manawa pōkole loa, hiki ke komo i ka ʻili a hiki pololei i ka Basal Layer o Epidermis a me Dermis e pahū koke i ka melanin.Hoʻopili ʻia nā melanin cell i loko o nā ʻāpana ʻai, ʻai ʻia kekahi o lākou e nā cell immune, hoʻomaha ʻia i waho o ke kino.E hoʻoneʻe mālie ʻia ka pigmentation a i ʻole ka peʻa ma hope o ka mālama ʻana ma muli o ka emi ʻana o ka melanin.ʻO ka hope, hiki ke hoʻokō ʻia ka pigmentation piha a i ʻole ka wehe ʻana i ka peʻa.
ʻO ka ʻike ʻana o ka ʻili i ka nanosecond-domain laser pulses e pili ana i ka ʻōnaehana pigmentary ma ke kaʻina i kapa ʻia ʻo selective photothermolysis, kahi e hoʻololi maikaʻi ʻia ai nā melanosome a me nā cell pigmented.Ma muli o ka laulā absorption spectrum o ka melanin, hiki mai kēia hopena me nā lōʻihi nalu e komo i nā hohonu ʻokoʻa loa i loko o ka ʻiʻo, hiki ke hana i nā pane olaola like ʻole.Ua hoʻoholo ʻia nā hopena o kahi kokoke-ultraviolet (355 nm), ʻike ʻia (532 nm), a kokoke i ka infrared (1064 nm) o ka lōʻihi o 10-12 nsec i ka ʻili puaʻa guinea me ka hoʻohana ʻana i nā hiʻohiʻona microscopic gross, histologic, a electron.ʻO ka pane ʻana o ka paepae i loko o ka ʻili pigmented he transient koke ka lehu-keʻokeʻo discoloration, e koi ana i ka 0.11, 0.20 a me 1.0J/cm2, ma 355, 532, a me 1064 nm.Ma kēlā me kēia nalu nalu, ua kaulana nā melanosome i loko o nā keratinocytes a me nā melanocytes, me nā cytoplasmic a me nā hoʻololi nuklea.Ua lohi ka epidermal depigmentation, a ukali ʻia e ka repigmentation mālie.Ua hoʻololi wale ʻia nā cell follicular hohonu ma 532 a me 1064 nm, i hana i ka leukotrichia mau loa.Ua kūlike ka spectrum hana no ka pane paepae me nā mīkini i kuhikuhi ʻia e ka photothermolysis koho.Pono paha kēia mau ʻikepili no ka noʻonoʻo ʻana i ka mālama ʻana i nā mea ʻino o ka pigmentation ʻili a i ʻole ka pigmentation follicular makemake ʻole, a i ʻole nā mea ʻelua.
