Methylene blue iri muri liposome: ubushakashatsi ku kuyigeza aho igenewe n'ibivugwa ku bicuruzwa
Ijambo “liposomal” risobanura imiterere ikoreshwa mu gutwara umuti ukagezwa aho ugenewe. Ryonyine ntirigaragaza ko umuti winjira neza kurushaho mu mubiri, ko ugera neza kurushaho mu bwonko, cyangwa ko ugira inyungu ku buzima. Ku bijyanye na methylene blue, ubushakashatsi bwatangajwe ku bitwara umuti burimo ibigeragezo byo muri laboratwari bikoresha umuti ukorana n'urumuri n'ubushakashatsi buto ku bantu bwakoresheje umuti usigwa ku ruhu. Ibyo bwagaragaje bireba gusa imitegurire y'umuti, uburyo watanzwe n'ibipimo by'ibisubizo byasuzumwe.
Bityo rero, ikibazo gifasha mu kugura ni iki cyihariye: ni ibihe bimenyetso bihuza iki gicuruzwa cyarangiye gutegurwa n'inyungu ivugwa ku kirango cyacyo? Ubushakashatsi bugaragaza ingaruka zikomeye kurushaho zo gukoresha urumuri ku gatsiko k'ibinyabuzima bitagaragara bifatanye ku buso ntibushobora gusubiza ikibazo cy'ingano ya methylene blue ijya mu maraso y'umuntu nyuma yo kumira igicuruzwa cy'amazi kidafitanye isano n'icyasuzumwe.
Ibyo liposome irimo
Liposome ni agafuka gato gafite agahu kagizwe n'ibice bibiri by'ibinure, rimwe na rimwe hakabamo ibindi bice bibiri bibiri bikikije ahantu hamwe hagati. Amazi aba mu gice cyo hagati. Molekile z'umuti zishobora gufatana n'ibice bitandukanye by'iyo miterere bitewe n'imiterere yazo ya shimi n'uburyo umuti wateguwe. Umuti umwe ushobora no kuguma hanze y'utwo dufuka.
Ishusho yo ku gifuniko yerekana mu buryo bworoshye agatwara umuti gafite ibice bibiri gusa by'ibinure, hamwe n'utudomo tugereranya methylene blue imbere no hanze yako. Yerekana ibice bitandukanye, ntabwo yerekana ingano yapimwe y'umuti washyizwemo cyangwa uko molekile zikwirakwijwe mu gicuruzwa kigurishwa.
Kuba lecithin iri ku rutonde rw'ibigize igicuruzwa ntibihagije kugira ngo byemeze ko harimo liposome zirimo umuti kandi zigumana imiterere yazo. Uwukora igicuruzwa agomba kugaragaza iyo miterere no gupima ingano y'umuti gitwaye. Amabwiriza ya FDA ku bicuruzwa by'imiti ikoresha liposome atandukanya liposome n'ibinyabutabire bihuza umuti n'ibinure bitari mu dufuka, kandi afata igenwa ry'ibiranga imikorere y'umuti n'uko umuti ugenda mu mubiri w'umuntu nk'ibibazo bitandukanye. Aya ni amabwiriza agenewe ubusabe bwo kwemeza imiti, ntabwo ari ikimenyetso cy'iyemezwa ry'ibicuruzwa bikoresha ijambo “liposomal.”
Ibindi bitwara umuti ni uburyo butandukanye. Cyclodextrin ni karubohayidire zifite ishusho y'impeta zikoreshwa mu guhuza umuti n'ikindi kinyabutabire; uduce duto cyane twa polimere dukoresha agatwara umuti gashingiye kuri polimere. Nta na kimwe muri ibyo kiba liposome kubera gusa ko ari gito cyangwa kirimo methylene blue.
Ibipimo bitanu bishyigikira ibivugwa bifite ishingiro ku mitegurire y'umuti
Amabwiriza ya National Cancer Institute yo kugena ibiranga liposome atandukanya ibigize umuti, imiterere yawo igaragara n'ingano y'umuti urimo. Inyandiko y'igicuruzwa ifite akamaro igomba kugaragaza neza itandukaniro rikurikira:
- Ingano y'uduce n'uko iyo ngano itandukanye. Impuzandengo ya diyametero ihisha urugero ingano z'uduce zitandukaniyeho. Igipimo cy'uko ingano z'uduce zitandukanye gifasha gusobanura iryo tandukaniro. Gupima ingano gusa ntibyemeza ko hari ibice bibiri by'ibinure.
- Ibigize agatwara umuti n'imiterere yako. Kumenya ubwoko bw'ibinure, ibipimo byabyo n'amashusho agaragaza imiterere bifasha gutandukanya udufuka n'andi matsinda y'uduce dufatanye. Urutonde rw'ibigize igicuruzwa rutangwa n'umucuruzi ntirushobora gusimbura ibipimo by'umuti warangiye gutegurwa.
- Methylene blue yose, itari mu dufuka n'ifungiye mu dufuka. Ubwinshi rusange bugaragaza ingano y'irangi ririmo. Igipimo cy'ubushobozi bwo gufungira umuti mu dufuka gisobanura igice kijyanye n'uburyo umuti washyizwemo. Ingano y'umuti ushyizwe mu gatwara igaragaza ingano y'umuti ugereranyije n'ibikoresho bigize agatwara; raporo igomba kuvuga icyo ibarura ryashingiyeho.
- Kurekurwa no kuva mu gatwara. Abashakashatsi bagomba gupima niba umuti uva mu gatwara, uko ubikora vuba n'imiterere y'ibizamini bibikorwamo. Igisubizo cyo kurekurwa k'umuti mu gisukika kimwe kigumana urugero rwa pH ntabwo ari igipimo cy'uko winjira mu mubiri w'umuntu.
- Kugumana imiterere uko igihe gihita. Kwegerana kw'uduce, kuva kw'umuti mu gatwara no kwangirika mu buryo bwa shimi ni uburyo butandukanye umuti ushobora kwangirika. Ibisubizo bigomba kugaragaza ubushyuhe, urumuri umuti wahuye na rwo, ikibitswemo n'igihe gihuye n'ibivugwa ku kubika igicuruzwa.
Urugero rufatika rugaragaza impamvu ibi ari ngombwa. Mu bushakashatsi bwa 2019 kuri liposome bwakoresheje uturemangingo twa kanseri y'ibere, ingano y'uduce yagumye hafi ya 160 nanometers mu minsi 14 twakurikiranywemo. Ikigeragezo gitandukanye cyo kurekurwa k'umuti cyagaragaje ko hafi 95% bya methylene blue byavuye muri liposome mu masaha umunani. Kugumana diyametero y'uduce no gukomeza kugumana umuti ni ibiranga umuti bitandukanye. Nta na kimwe muri ibyo bipimo cyari igisubizo cy'uko umuti umirwa winjira mu mubiri w'umuntu.
Kugereranya uburyo bwo gutwara umuti: ibipimo n'ibisubizo
Iri gereranya ritandukanya ikibazo cy'agatwara umuti n'icy'ibibera mu binyabuzima. Inkingi y'ibipimo igaragaza ibizamini bifitanye isano n'ubwo buryo, ntabwo ivuga ko buri bushakashatsi bwashyizwe ku rutonde bwakoze buri kizamini.
| Uburyo bwo gutwara umuti | Ibipimo by'imitegurire y'umuti bifite akamaro | Ibipimo by'ibisubizo byasuzumwe koko mu bushakashatsi bwavuzwe | Ibyo budashobora kwemeza ku gicuruzwa kigurishwa kigenewe kumirwa |

| Methylene blue iri mu dufuka dufite ibice bibiri by'ibinure | Itandukaniro ry'ingano z'uduce, ibigize ibinure, umuti utari mu dufuka n'ufungiyemo, kurekurwa k'umuti, kugumana imiterere mu bubiko | Kwinjira mu turemangingo, ingaruka ku turemangingo zikangurwa n'urumuri, cyangwa ibipimo by'ibisubizo ku dutsiko tw'uduhumyo dufatanye ku buso mu bushakashatsi bwo muri laboratwari | Kwinjira neza kurushaho mu mubiri unyuze mu rwungano ngogozi cyangwa kunoza ubushobozi bwo gutekereza |
| Methylene blue iri muri liposome zo muri hydrogel isigwa ku ruhu | Ibiranga udufuka, kurekurwa k'umuti muri gel, aho umuti ujya mu ruhu | Umubare w'ibiheri bya acne n'isuzuma ryo kwa muganga mu igeragezo rito ry'umuti usigwa ku ruhu ukorana n'urumuri | Inyungu zo kumira liposome, cyangwa ubushobozi bwo kuvura hatabayeho uburyo bwateganyijwe bwo kuvura hakoreshejwe urumuri |
| Methylene blue hamwe na beta-cyclodextrin | Ubwoko bw'ikinyabutabire gihuza umuti n'agatwara cyangwa ubw'agatwara, uko umuti ufatana na byo, ubwinshi, kugumana imiterere | Umubare w'ibinyabuzima bitagaragara bikiri bizima mu gatsiko k'ibinyabuzima byo mu kanwa byafatanye ku buso, muri laboratwari hakoreshejwe urumuri rutukura | Imikorere ya liposome, kwinjira mu maraso, cyangwa kuvura indwara iterwa n'ibinyabuzima bitagaragara mu muntu |
| Methylene blue iri mu duce duto cyane twa polycaprolactone | Ibigize polimere, ingano, ingano y'umuti washyizwemo, kurekurwa k'umuti, ibiranga ubuso | Kwinjira mu ruhu n'ingaruka zangiza uturemangingo twa kanseri ziterwa n'urumuri mu bushakashatsi ku gutanga umuti usigwa ku ruhu bukoresha ultrasound | Ubushobozi bwo kuvura kanseri mu bantu cyangwa urugero umuti uri muri liposome zigenewe kumirwa ugeraho mu maraso |
Urugero rwa polimere ruva mu bushakashatsi buhuza uduce duto cyane twa polycaprolactone na sonophoresis, uburyo bwo kugeza umuti aho ugenewe bufashwa na ultrasound. Rugaragaza impamvu ibikoresho bigize agatwara umuti n'uburyo bw'inyongera bukoreshwa hamwe na ko byombi ari ngombwa.
Ibyo ubushakashatsi kuri methylene blue bugaragaza koko
Mu bushakashatsi kuri liposome na Candida auris bwatangajwe kuri interineti mu Kuboza 2025, abashakashatsi bagereranyije ibitwara umuti bifite amashanyarazi meza n'ibifite amashanyarazi mabi na methylene blue itari mu gatwara. Imitegurire ikoresha liposome yatumye umuti ugera neza kurushaho mu dutsiko tw'ibinyabuzima bifatanye ku buso muri laboratwari, kandi yongera ingaruka zibangamira utwo dutsiko zikangurwa n'urumuri. Ariko ubwinshi buto cyane bwari bukenewe kugira ngo bwice uturemangingo tw'uduhumyo twereraga mu gisukika bwari bungana n'ubw'irangi ritari mu gatwara. Inyungu yagaragaraga yaterwaga n'imiterere ibinyabuzima byari birimo n'igipimo cy'igisubizo cyasuzumwe.
Iyo nyandiko yanagaragaje ibipimo by'ubushobozi bwo gufungira umuti mu dufuka bya hafi 11% na 14% ku mitegurire yombi. Ibiranga imiterere yazo byapimwe byagumye uko byari biri mu minsi 30 zibitswe ahakonje kandi hijimye, ariko nyuma hagaragara ko zitakigumana imiterere yazo. Ibi ni ibyagaragaye bifasha mu gutegura umuti, ntabwo ari ibipimo bishobora guhita byitirirwa icupa ry'undi muntu ukora igicuruzwa.
Ubushakashatsi bwa 2021 kuri beta-cyclodextrin bwakoresheje agatsiko k'ibinyabuzima byo mu kanwa byo mu bwoko butandukanye byafatanye ku buso, kakuriye mu masahani mato y'ibizamini mu masaha 24. Ubuvuzi bwahuje agatwara methylene blue n'urumuri rutukura rwa laser cyangwa LED, maze hasuzumwa umubare w'ibinyabuzima bitagaragara bikiri bizima. Aha “agatsiko k'ibinyabuzima byo mu kanwa bifatanye ku buso” bivuga ibinyabuzima bifitanye isano n'akanwa. Ntibivuga ko umuti wateguwe wamizwe cyangwa ko hapimwe urugero ugeraho mu maraso nyuma yo kumirwa. Iri tandukaniro ni ingenzi mu gusobanukirwa ubushakashatsi ku dutsiko tw'ibinyabuzima bifatanye ku buso hakoreshejwe urumuri.
Ibimenyetso ku bitwara umuti byakoreweho ubushakashatsi mu bantu ntibibuze burundu. Ubushakashatsi buto kuri acne, aho abarwayi bashyizwe mu matsinda ku buryo bw'amahirwe kandi umushakashatsi atazi itsinda buri wese arimo, bwavuye abarwayi 13 hakoreshejwe hydrogel irimo methylene blue iri muri liposome hamwe n'ubuvuzi bukoresha umuti ukorana n'urumuri. Bwatangaje ko habaye impinduka nziza mu mubare w'ibiheri no mu isuzuma ryo kwa muganga nyuma y'inshuro ebyiri z'ubuvuzi, abarwayi bakurikiranwa kugeza ku byumweru 12. Ubundi bushakashatsi ku mitegurire y'umuti bwasuzumye kurekurwa k'umuti no kuwugeza aho ugenewe mu ruhu rw'imbeba. Umubare muto w'abarwayi, kuwusiga ku ruhu n'ubuvuzi bushingiye ku rumuri bigabanya ibyo ubu bushakashatsi bushobora kwemeza. Ntabwo ari igereranya rya methylene blue iri muri liposome imirwa n'iya methylene blue isanzwe.
Ni iki cyashyigikira kuvuga ko umuti winjira neza kurushaho mu mubiri?
Kuvuga ko umuti umirwa winjira neza mu mubiri bisaba ubushakashatsi mu bantu ku muti warangiye gutegurwa bireba, uwo kugereranya na wo ukwiye, ingano za methylene blue zigereranywa, n'uburyo busobanutse bwo gufata no gusesengura ibyitegererezo. Ibipimo by'ingano y'umuti umubiri uhura na yo, nk'ubuso buri munsi y'umurongo ugaragaza ubwinshi bw'umuti uko igihe gihita, bisobanura uko umubiri uhura n'umuti mu gihe runaka. Kuba ubwinshi bwo hejuru bwagezweho ari bwinshi kurushaho ntibyonyine byemeza ko ingano yose yinjiye mu mubiri ari nini cyangwa ko igisubizo cy'ubuvuzi ari cyiza kurushaho.
Methylene blue isanzwe iri mu mazi isanzwe ifite amakuru ku kwinjira mu mubiri w'umuntu. Ubushakashatsi bwo mu cyiciro cya I bwakoresheje uburyo bwo guhinduranya uburyo bwo guhabwa umuti mu bakorerabushake 16 bafite ubuzima bwiza bwatangaje ko impuzandengo y'urugero nyakuri rw'umuti wageraga mu maraso yari 72.3%, ariko ikaba yaratandukanye cyane hagati y'abantu, ku muti wo mu mazi wasuzumwe. Ibi ntibyemeza ijanisha rimwe ryo kwinjira mu mubiri rireba buri gihe, kandi ntibigaragaza uko uwo muti urutana n'ibicuruzwa birimo liposome. Ariko bihungabanya igitekerezo cy'uko methylene blue igomba byanze bikunze gukenera liposome kugira ngo yinjire mu mubiri.
Ubushakashatsi bw'ibanze bwabonetse mu gutegura iyi nyandiko ntibwatanze igeragezo mu bantu rigereranya imiti imirwa, rigaragaza ko methylene blue iri muri liposome igurishwa yinjira neza kurushaho mu mubiri. Iyo ni imbogamizi y'ibimenyetso byabonetse, ntabwo ari gihamya y'uko nta bushakashatsi nk'ubwo bushobora kubaho. Kwinjira mu mubiri no gukwirakwira kw'umuti bitewe n'uburyo watanzwe na byo bisaba gusobanurwa ukwabyo, bitandukanijwe n'inyungu mu buvuzi.
Uko wasuzuma ikirango kivuga ko umuti uri muri liposome cyangwa wateguwe mu buryo bwihariye
Saba ibimenyetso ku gicuruzwa nyirizina: ubwinshi bwa methylene blue kirimo, igenwa ry'ibiranga agatwara umuti, ibizamini by'ibyakozwe mu cyiciro kimwe, kugumana imiterere mu bubiko, n'igereranya ryose ryakorewe mu bantu rishyigikira inyungu yamamazwa. Icyemezo gipima gusa ubuziranenge bw'irangi ntigishobora kwemeza ko ryafungiwe mu dufuka cyangwa uko ryinjira mu mubiri. Blupreme igurisha methylene blue; iyi nyandiko ntigaragaza ikirango cya liposome ikunda kurusha ibindi. Koresha urutonde rumwe rwo kugereranya ibicuruzwa rugenewe abaguzi ku bacuruzi bose.
Imvugo “methylene blue iri muri liposome yateguwe mu buryo bwihariye” yongeraho amakuru ku buryo umuti wateguwe, ntabwo ari gihamya y'uko ugezwa neza kurushaho aho ugenewe. Muri Leta Zunze Ubumwe za Amerika, imiti itegurwa mu buryo bwihariye ntabwo yemewe na FDA. Umufarumasiye cyangwa uwandika umuti agomba kuba ashobora gusobanura intego y'imitegurire yawo n'ibimenyetso bishyigikira uburyo uteganyijwe gutangwamo. Gufungira umuti mu dufuka ntibigomba gufatwa nk'uburyo bwo kwirengagiza ibyitonderwa bizwi ku mutekano wa methylene blue.
Mu kugereranya umuti ushonge n'ifu cyangwa imiti iri mu dufuka n'ibinini n'umuti w'amazi utangwa mu bitonyanga, tandukanya korohereza uyikoresha, ibiyirimo bigaragazwa n'inyandiko, n'imikorere yayo mu buvuzi. Ishyurira ikiranga cyagaragajwe n'ibimenyetso, aho kwibwira ko izina ry'agatwara umuti ritanga ibimenyetso bibura.
