Methylene blue negomarara: zvakawanikwa murabhoritari zvichienzaniswa neuchapupu kubva kuvarwere

Methylene blue inouraya masero egomarara here? Mundiro yerabhoritari, kazhinji hongu. Mhinduro iyoyo inoshamisa vanhu, saka inopararira zvikuru. Dambudziko nderekuti mumhinduro iyoyo munopinzwa mumwe mubvunzo pasina kuujekesa: methylene blue inorapa gomarara muvarwere here? Pamubvunzo iwoyo, zvinyorwa zvetsvakurudzo zvinopa mhinduro yakasiyana, uye kuvhiringidzika kwakawanda paindaneti kunobva pakusanganisa mapurogiramu matatu etsvakurudzo anoshandisa dhayi rimwe chete asi achiedza nzira dzakasiyana dzekupindira.

Zvione sepfungwa nhatu dzine zita rimwe chete. Pfungwa yekutanga ndeyemushonga unoisa chepfu mumabundu uri woga. Yechipiri ndeyechinhu chinongotanga kuva chepfu panosvika chiedza. Yechitatu ndeyedhayi rebhuruu rinobatsira anovhiya kuona. Mhedzisiro yeimwe haiiti kuti zvimwe zviviri zvive nemhedzisiro imwe chete. Kana wanzwisisa musiyano iwoyo, uchapupu hunokurumidza kujekera.

Zvinonyatsotaurwa netsananguro iri muduramazwi regomarara

Ts ananguro yemethylene blue muduramazwi reNational Cancer Institute inotsanangura dhayi rebhuruu rakagadzirwa rinobatana nezvikamu zvemasero zvine chaji yemagetsi isina kunaka, zvakaita senucleic acids. Pakushandiswa mugomarara, inotsanangura kubaiwa kwaro mutishu dze lymph panguva yekuvhiya kuti ripende mapfundo e lymph anogamuchira mvura inoyerera kubva munzvimbo yacho, kuitira kuti anovhiya aawane. Inotaurawo zvakasiyana nezvekushandiswa kwaro mutsinga pakuchinjanisa maerekitironi, kana kuti redox, mumethemoglobinemia.

Tsananguro iyoyo hairatidzi methylene blue semushonga wegomarara wakatogamuchirwa. Kuva nelink rekutsvaga miedzo pane peji iri chinhu chinowanzoiswa mumaduramazwi, kwete mutongo wekuti mushonga unoshanda. Kana munhu akashandisa peji reNCI seuchapupu hwekuti methylene blue yakagamuchirwa pakurapa gomarara, anenge asina kunzwisisa rudzi rweruzivo runopiwa neduramazwi.

Kuuraya zvakananga pasina chiedza: kumasero hongu, kuvarwere kwete

Tsananguro yemashandiro inonyanya kutaurwa ndeyeongororo yemethylene blue semumwe mutakuri wemaerekitironi mumitochondria. Pfungwa yayo iri nyore. Methylene blue inogamuchira maerekitironi kubva kuNADH pedyo necomplex I yoapfuudza yakananga kucytochrome c, ichidarika zvikamu zvakakuvadzwa zvenhevedzano inoshandiswa nesero pakufema. Mumasero anokuriswa murabhoritari, kuchinja ikoko kunowedzera kushandiswa kweoxygen, kunoderedza glycolysis nekugadzirwa kwelactate, uye kunodzosera mashandisirwo ezvokudya zvesero kunzira yeoxidative phosphorylation.

Paglioblastoma, muyedzo wakavakirwa pfungwa iyi wakashandisa masero emabundu akakuriswa murabhoritari. Masero akapiwa mushonga akaratidza kudzokera shure kwekuchinja kunonzi Warburg, kunonoka kwekuwanda kwawo, kutanga kwemasaini ekushomeka kwesimba kuburikidza neAMPK, uye kumira paS-phase yenhevedzano yekukura nekupatsanuka kwesero. Ndipo panobva mashoko ekuti methylene blue inodzosera shure Warburg effect. Izvi zvakanyatsoonekwa, asi zvakaonekwa mundiro dzerabhoritari chete.

Tsvakurudzo yakatevera inokosha haiwanzotaurwa. Boka rimwe chete parakaedza pambeva dzaiva nemaglioblastoma evanhu akaiswa madziri, richipa methylene blue kuti isvike mumuviri wose, nzira yemashandiro yaitarisirwa haina kutanga kushanda uye mabundu haana kuderera. Pane zvakamboonekwa mumhuka kare, kusanganisira mushumo wemuna 1989 wembeva dzakashandiswa mumienzaniso yeascites neleukemia, umo kukura kwemabundu kwakanonoka. Asi zvinyorwa zvakaiswa mumatura etsvakurudzo hazvina tsananguro yakakwana yemaitiro inodiwa nemuverengi wemazuva ano, uye hapana mutsvakurudzo iyi chakazosvika pamuyedzo une boka rekuenzanisa muvanhu wemethylene blue inopiwa kuti isvike mumuviri wose ichiuraya mabundu. Tsananguro yemakemikari yekufambiswa kwemaerekitironi nemethylene blue inoratidza kuti nei kushanda uku kuchitsamira pamamiriro acho, kwete kuti nei murwere achifanira kukutarisira.

Panewo uchapupu hunopesana neizvi hunobva kutsvakurudzo yehupfu. Chidzidzo chemakore maviri cheNational Toxicology Program chakapa makonzo nembeva mushonga nechubhu yaipinza mudumbu, chikawana anemia yaienderana nehuwandu hwemushonga pamwe nekuwedzera kwemabundu epancreatic islet neura hudiki mumhuka. Basa rerabhoritari pamusoro pekukuvadzwa kweDNA kunoitika pasina chiedza kuchibatsirwa nesimbi rinoratidzawo chikonzero chekuchenjerera. Hapana chimwe cheizvi chinoratidza zvechokwadi njodzi kuvanhu pahuwandu hupi nohupi hwavangasangana nahwo, asi chinoramba pfungwa yekuti dhayi rinoshanda pakuchinjanisa maerekitironi rinofanira kunge risina ngozi nokuti rava nenguva refu richishandiswa. Mufananidzo wakazara unofanira kutariswa pamwe chete neuchapupu hwekuchengeteka kwemethylene blue.

Kurapa kwephotodynamic: dhayi rimwe chete, nzira yakasiyana

Kurapa kwemethylene blue kwephotodynamic hakusi kupa mushonga kuti usvike mumuviri wose wozongowedzera chiedza sechimwe chinhu chisina kukosha. Inzira inoshandiswa panzvimbo imwe chete: dhayi rinoiswa mukati kana pamusoro penzvimbo ine chironda, rozovhenekerwa nechiedza chine wavelength inotorwa nedhayi racho. Izvi zvinogadzira singlet oxygen nemaradicals zvinoparadza tishu dziri pedyo mukati me micrometers. Huwandu hunoratidza hupfu pasina chiedza nehune chiedza hunogona kusiyana nekakapetwa gumi, saka kutaura nezvekuuraya masero mundiro usina kutaura huwandu hwechiedza chakashandiswa hakuna zvazvinoreva.

Uchapupu hwevanhu pano hushoma uye hunongobata nzvimbo yakarapiwa. Chiratidzo chidiki chakasimba kupfuura zvimwe chiri munodular basal cell carcinoma. Muchidzidzo chaitevera varwere kubva pakutanga, varwere 20 vakapiwa dhayi pamusoro penzvimbo yaiva negomarara, vakabaiwa dhayi mukati menzvimbo dzakakura, vozovhenekerwa nechiedza. Chakashuma kuti zviratidzo zvegomarara zvakanga zvanyangarika zvachose mu11 ve17 vakapedza chidzidzo pamwedzi mitanhatu, paine biopsy payaidiwa. Pakanga pasina boka rekuenzanisa rakasarudzwa zvisina kurerekera. Kunze kweizvozvo kune mishumo yezviitiko zvishoma, yakadai sezviitiko zvitatu zvegomarara rakadzoka mugurokuro zvakateverwa kuti zvionekwe kufa kwetishu panzvimbo yakarapiwa, uye chiitiko chimwe cheKaposi sarcoma chakashandisawo toluidine blue, saka mhedzisiro yacho haigoni kunzi yakakonzerwa nemethylene blue chete.

Zvimwe zvese zvinowanzotaurwa zvinobva kutsvakurudzo isati yasvika pakuyedzwa muvanhu. Ongororo yakarongeka yemuna 2023 yebasa remethylene blue photodynamic yakawana zvidzidzo zvemhuka gumi chete zvaizadzisa zvinodiwa, zvichisanganisira mienzaniso yegomarara remuura hukuru nerectum, melanoma nerezamu, pakati pemamwe. Yakatsanangura bazi iri serisati rasvika pakuyedzwa muvanhu. Mabundu egomarara remuura hukuru nerectum akaiswa mumbeva, akabaiwa dhayi panzvimbo iyoyo ozovhenekerwa, akaratidza kuparadzwa kukuru panzvimbo yacho. Tsvakurudzo yedundira, muromo nemelanoma inoshuma kuderera kwekukwanisa kurarama kwemasero, apoptosis kana kuderera kwekubudirira kwekubata nekukura kwebundu mumasero nemhuka, kwete kupindura kwemabundu evarwere kana kurarama kwavo. Kurapa nechiedza panzvimbo ine chironda cheganda hakutauri chinhu nezvekunwa mvura ine mushonga nokuda kwegomarara rapararira. Izvi zvinosiyana nenzira yekupinza mushonga, huwandu hunosvika panzvimbo inonangwa, chiedza, rudzi rwebundu uye chinoyerwa pakupedzisira.

Dhayi rebhuruu pakuvhiya: kubatsira kwakaratidzwa, asi chinoyerwa hachisi kurapa

Bazi rine tsvakurudzo yakawanda chaizvo muvanhu rinoedza kubatsira kuona, kwete kuuraya. Pakuvhiya rezamu, kuenzanisa methylene blue nepatent blue muvarwere 142 vakaiswa mumapoka zvisina kurerekera kwakayera kuwanikwa kwemapfundo e lymph anotanga kugamuchira mvura kubva pabundu, kwete kuderera kwebundu. Kwakawana mwero wekuwana mapfundo unosvika 61 percent uchienzaniswa ne68 percent, pasina musiyano wakakosha pahuwandu. Muyedzo mudiki wevarwere 60 vakaiswa mumapoka zvisina kurerekera wakaenzanisa dhayi roga nedhayi rakabatanidzwa neradiocolloid, uchiyera kunyatsoona mapfundo uye mwero wemhedzisiro yaiti hapana dambudziko asi riripo. Zvakare, chinangwa chakayerwa chaiva kuwana mapfundo, kwete kurapa gomarara.

Kuongorora nechubhu ine kamera kunoratidza zvakafanana. Muyedzo wevarwere 165 vane ulcerative colitis, vakaiswa mumapoka zvisina kurerekera, wakaenzanisa chromoendoscopy inoshandisa methylene blue pamusoro petishu necolonoscopy yakajairika, uchiyera kuonekwa kwenzvimbo dzine shanduko dzinogona kuzova gomarara. Wakawana kuti nzvimbo dzakawanda dzakadaro dzakaonekwa. Chidzidzo chechikamu III chekuongorora varwere 1,205, vachishandisa dhayi rinonwiwa rakanangidzirwa kuura hukuru, chakayera mwero wekuwanikwa kwemaadenoma. Mwero wacho wakakwira kubva panenge 48 kusvika 56 percent, pasina kutaura kuti kwaiva kurapa. Chidzidzo chevarwere gumi nevaviri chekuona kana nzira ichikwanisika chakashandisa dhayi rinopinzwa mutsinga pamwe nemifananidzo yechiedza chiri pedyo neinfrared kuti chione machubhu anotakura weti kubva kuitsvo kuenda kudundira panguva yekuvhiya gomarara remuhudyu. Chakashuma kuti machubhu acho ese ari maviri akaonekwa mumurwere mumwe nomumwe. Zvinobatsira pakuvhiya, asi hazvisi uchapupu hwekuti dhayi rakaderedza bundu ripi neripi. Nhungamiro yekuverenga chidzidzo chemethylene blue iripo nokuti zvinoyerwa pakuona dambudziko zvinowanzotaurwa sezvinoyerwa pakurapa.

Tafura yezvidzidzo: bundu, muenzaniso, nzira yekupinza, uye zvakanyatsoyerwa

Tanga waverenga pasi pekoramu yezvakayerwa usati waverenga musoro upi noupi. Kana chakayerwa chiri lactate kana kukwanisa kurarama kwemasero, chidzidzo hachigoni kutsigira mashoko ekurarama kwevarwere. Kana chakayerwa chiri kuwanikwa kwenzvimbo dzine dambudziko, hachigoni kutsigira mashoko ekurapa.

Maitiro epaindaneti: ongorora musanganiswa, gomarara, uye mhedzisiro

Nzira dzine mazita dzinopararira paindaneti dzinowanzosanganisa methylene blue nemushonga wezvipembenene zvakaita sefenbendazole kana ivermectin, dzimwe nguva dzichiwedzera kutsanya, uye dzichibatanidza nyaya dzevarwere. Chinhu chimwe nechimwe chinoda mibvunzo mitatu imwe chete: musanganiswa iwoyu chaiwo wakaongororwa here, mugomarara ripi, uye paine mhedzisiro ipi yakayerwa?

Hapana muyedzo une boka rekuenzanisa wakaonekwa wemusanganiswa wakakurumbira wemethylene blue nefenbendazole neivermectin, pamwe kana pasina kutsanya. Mushumo mutsva uri pedyo zvikuru neizvi unopesana nenyaya yacho. Mushumo wemuna 2026 wechiitiko chemelanoma yakapararira wakatsanangura munhu ane makore 74 akazvipa ivermectin, fenbendazole, methylene blue nezvimwe zvakawanda zvekuwedzera mushure mekuramba kurapwa kunosvika mumuviri wose. Mifananidzo yekuongorora neDNA yebundu yaitenderera muropa zvakaratidza kuvandudzika pakutanga, ndokuzoratidza kuwedzera kwechirwere. Vanyori vakaona kuti kuderera kwegomarara kwakangoitika kuburikidza nekudzivirirwa kwemuviri kwaigona kutsanangura izvi zvakangofanana nedzimwe tsananguro, tichifunga kuwanda zvikuru kweshanduko dzeDNA yebundu. Murwere mumwe chete asina boka rekuenzanisa, achitora zvinhu zvakawanda panguva imwe uye zvisinganyatsozivikanwi kana aizvitora sezvakarongwa, haasi mhedzisiro inoratidza kushanda kwemaitiro aya.

Mashoko anobatanidzwa nenyaya iyi haapiwo rutsigiro rwuri nani. Mushumo wezviitiko zvevarwere vatatu vakatora fenbendazole, wakagovaniswa zvikuru, wakabviswa muna Ndira 2026 nekuda kwekupesana kwezvido kusina kuziviswa, uko magazini yakati kwaizochinja madudzirwo ezvakawanikwa. Chidzidzo cheivermectin pamwe nemushonga unovhara immune checkpoint mugomarara rezamu retriple negative chine boka rimwe chete, chichiri kunyoresa varwere, hachina mhedzisiro yakaburitswa, uye hachina methylene blue, fenbendazole kana kutsanya. Kutsanya pachako kunofanira kuiswa muboka rakasiyana: muyedzo wevarwere 131 vakaiswa mumapoka zvisina kurerekera wakashandisa kudya kunotevedzera kutsanya panguva dzakapoteredza chemotherapy inopiwa kuvhiya kusati kwaitwa mugomarara rezamu reHER2 negative. Wakayera hupfu nezviratidzo zvekupindura, uye kwaivawo nemuyedzo mudiki wevarwere 44 vegomarara rezamu mune zvakada kufanana. Izvi zvidzidzo zvezvinowedzerwa pachemotherapy, zvichiyera kupindura, kwete uchapupu hwekurarama hunotsigira maitiro edhayi pamwe nemushonga wezvipembenene. Uye muyedzo mukuru wekutsanya mugomarara remuura hukuru nerectum kusvika zvino wangoburitsa hurongwa hwemuyedzo chete. Tsananguro yezvakanyatsoongororwa netsvakurudzo yekutsanya inobatsira kuramba ichipatsanura mapoka aya.

Nyaya dzevarwere dzinofanira kunzwirwa tsitsi, asi dzichiri rudzi rweuchapupu husina kusimba kupfuura rumwe rwese. Nyaya idzi dzinonyanya kuratidza vakararama vanonyora paindaneti, dzinosiya kurapwa kwakajairika kwaiitwa panguva imwe chete, uye hadziratidzi huwandu hwese hwevanhu vakaedza nzira yacho. Nyaya inogona kukurudzira muyedzo. Haigoni kuutsiva.

Chimwe chinhu chekupedzisira chinobatsira varwere vari kutorapwa gomarara. Methylene blue haisi chinhu chekuwedzera chisina zvachinochinja. Kushandiswa kwayo kwakabvumirwa ndekwemethemoglobinemia yakawanikwa, ichipiwa pasi pekutarisirwa, uye inodzivisa monoamine oxidase type A pahuwandu hwe nanomolar. Izvi zvinokonzera kudyidzana kwakanyorwa nemishonga yekuora mwoyo inoshanda paserotonin. Ani naani ari kufunga kuishandisa pamwe nekurapwa kwegomarara anofanira kutanga aendesa chigadzirwa chacho chaicho, huwandu hwaanofunga kutora, uye runyorwa rwakazara rwemishonga yake kuchikwata chinomurapa gomarara, nokuti uchapupu hwemiedzo huri pamusoro hahupi chikonzero chine chekuita nekurarama chekugamuchira imwe njodzi.

Mashandisirwo euchapupu uhu

Ani naani akatarisana negomarara achiverenga nezvemethylene blue anofanira kubvunza mibvunzo mina pamusoro pechinyorwa chimwe nechimwe chinotaurwa. Paiva nechiedza here kana kuti pakanga pasina, nokuti kuuraya kunoitwa nephotodynamic hakufanotauri kuuraya kunoitika mumuviri wose. Muenzaniso waiva ndiro yerabhoritari, mhuka, kana varwere vakaiswa mumapoka zvisina kurerekera here, nokuti chekupedzisira chete ndicho chinogona kuratidza kubatsira varwere.
