Amazinga ekhwalithi e-methylene blue: kusho ukuthini ezobuchwepheshe, i-reagent, i-aquarium, ne-USP
Ilebula le-methylene blue lingachaza izinto ezintathu ezihlukene: izimfuneko le nto ehlangabezana nazo, ukwakheka komkhiqizo osebhodleleni, noma ukusetshenziswa umhlinzeki akuhlosile. Lo mehluko unquma ukuthi yini ongayiphetha ngokufanele emagameni anjengokuthi eyezobuchwepheshe, i-reagent yaselabhorethri, eye-aquarium, ne-USP.
La magama awakhi uchungechunge olulodwa oluthembekile olusuka kukhwalithi ephansi luye kwephezulu. Umkhiqizo ungaba nemininingwane ecacile yokuwusebenzisa ukudaya isampula ngaphandle kokuthi wenziwe njengomuthi. Ingxube ye-aquarium ingaba nokwakheka okuchazwe ngokucacile ngaphandle kokufakazela ukuthi ifanele ukudliwa ngabantu. Qala ngokuthola ukuthi ilebula ngalinye lenza luphi uhlobo lwesimangalo.
Ukuqhathanisa incazelo yamalebula
Ithebula lihlukanisa isimangalo nobufakazi obudingekayo ukuze sihlolwe. Izibonelo zibonisa imikhakha, hhayi izincomo zokuthenga.

Umehluko waselabhorethri ulandela izincazelo ezishicilelwe yi-Fisher zamazinga ekhwalithi yamakhemikhali kanye nencazelo ye-ACS yezimfuneko zayo zama-reagent. Izibonelo zemikhiqizo nezemithethonqubo zihlolwa ngezansi.
Amalebula aselabhorethri achaza ukufaneleka komsebenzi othile
“Izinga le-reagent yaselabhorethri” liwulwazi olungaphelele ngaphandle kokuba umhlinzeki achaze ukuhlolwa okusekela lokho. Ilabhorethri ingase idinge udayi odaya amagciwane ngokungaguquguquki, i-reagent enamazinga alawulwayo ezinsimbi ezikhona ngobuncane, noma into efanele ukuhlaziya amanani. Lezo zimfuneko ziyahlangana, kodwa azifani.
Njengesibonelo esiqondile, i-Sigma-Aldrich M9140 methylene blue ifakwe ohlwini njengempushana eqinisekiswe yi-Biological Stain Commission, enokuqukethwe kukadayi okungenani okungu-82% futhi esetshenziselwa ukudaya amasampula. Lokho kuyincazelo yomkhiqizo eqondene nokusetshenziswa okuthile. Akusona isitatimende sokuthi iphesenti elisele liqukethe ukungcola okunobuthi, futhi akusona isimangalo sokusetshenziswa emithini.
Iphesenti lidinga incazelo. Okuqukethwe kukadayi, ukuhlanzeka okulinganiswa nge-chromatography, nesilinganiso sokuqukethwe esilungiselwe amanzi kuyizilinganiso ezihlukene. Ngakho ukuqhathanisa inombolo enkulu kunazo zonke ezinhlelweni ezimbili zemikhiqizo kungase kuqhathanise izici ezihlukene. Buza ukuthi kukalwe ini, ngayiphi indlela, futhi ngasiphi isisekelo ngaphambi kokubeka omunye umkhiqizo ngaphezu komunye.
Ukusetshenziswa ku-aquarium akulona izinga lokuhlanzeka elisebenza kuyo yonke imikhiqizo
Ulwazi lomkhiqizo we-methylene blue we-Kordon lunikeza isibonelo esiwusizo selebula lokusetshenziswa okuhlosiwe elihambisana nemininingwane yomkhiqizo. Luchaza usawoti we-chloride ongenayo i-zinc engxubeni yamanzi engu-2.303%, lukhomba ukusetshenziswa ku-aquarium, futhi lukhipha ngokusobala ukudliwa ngabantu. Luphinde lukhiphe ukusetshenziswa njengomuthi wezinhlanzi ezizodliwa.
Igama elithi aquarium likutshela ukusetshenziswa. Izinga lokugxila likutshela amandla engxube. Ukuthi ayinayo i-zinc kuchaza isici esisodwa sale nto. Asikho kulezo zitatimende esinikeza izimfuneko eziphelele zomuthi.
Ngokufanayo, akunasisekelo ukucabanga ukuthi wonke amabhodlela e-aquarium aqukethe insimbi esindayo ethile noma isithasiselo esithile. Thola ukwakheka komkhiqizo uqobo. Ungafaki ukuqinisekiswa noma ukusola esikhundleni sobufakazi obungekho. Ukuze wenze izinqumo eziqondene nezinhlanzi, sebenzisa umhlahlandlela ohlukile we-methylene blue yezinhlanzi ze-aquarium.
Okudingekayo ukusekela isimangalo se-USP
Ukubuka kuqala kombhalo wezindinganiso ze-USP Methylene Blue kuchaza into futhi kunikeza uhla lwesilinganiso sokuqukethwe olungu-97.0–103.0%, olubalwe ngokusekelwe entweni eyomisiwe. Umkhawulo ongaphezulu uwumkhawulo wokwamukelwa kwemiphumela yokuhlaziya, hhayi isimangalo sokuthi ibhodlela lingaqukatha into engaphezu kuka-100%. Ukuthi isilinganiso sisekelwe entweni eyomisiwe nakho kubalulekile lapho kuqhathaniswa into enamanzi esakhiweni sayo nomphumela wokuqukethwe kukadayi njengoba uhlinzekiwe.
Lokhu kubuka kuqala akuwona umbhalo ophelele wezindinganiso. Umphumela owodwa wokuhlola okuqukethwe ophumelele awukwazi ukufakazela ukuthi zonke izimfuneko ezisebenzayo zihlangatsheziwe. Buza ukuthi kusetshenziswe luphi uhlelo noma yiziphi izimfuneko ebezisebenza, bese ucela imibhalo ehlobene neqoqo elihlinzekiwe. Incazelo ehlukile ye-methylene blue yezinga le-USP ichaza lo mehluko kabanzi.
Phinde uhlonze ukuthi isimangalo sihlanganisa ini. “Yenziwe nge-methylene blue yezinga le-USP” kuphathelene nesithako. Ukuncibilikisa, ukufaka ezitsheni, nokugcina leso sithako kudala imibuzo eyengeziwe ngomkhiqizo oqediwe, kuhlanganise nezinga lokugxila, ezinye izithako, ukulawulwa kokungcola, ukupakishwa, nokuzinza.
Ilebula lomkhiqizo womuthi licacisa kakhulu. Ilebula le-ProvayBlue lango-2024 elisingathwe yi-FDA lichaza ingxube engenamagciwane efakwa emthanjeni equkethe i-methylene blue engu-5 mg/mL namanzi okujova, amandla ayo echazwe ngokwe-trihydrate. Lena imininingwane yomkhiqizo nendlela yokuyifaka emzimbeni. Isimangalo sesithako se-USP emkhiqizweni odayiswa ezitolo asiyinikezi leyo mininingwane.
Kungani amagama athi izinga lokudla nelabantu kudingeka ahlolwe ngokucophelela
Izinga lokudla kufanele liholele endinganisweni ethile nasekusetshenzisweni kokudla okuvunyelwe, hhayi enkolelweni ejwayelekile yokuthi ikhemikhali eluhlaza okwesibhakabhaka iyadliwa. Isifinyezo se-FDA sezithasiselo zombala ezivunyelwe asiyifaki i-methylene blue ohlwini lwemibala evunyelwe ekudleni kwabantu. Ukugunyazwa komkhakha noma ukusetshenziswa okukodwa akukwazi ukudluliselwa kokunye.
Kukhona nolunye ugibe lwemiphumela yokusesha: i-methylene blue ivela ohlwini lwe-FDA lwezinto ezithintana nokudla, olukhomba umthethonqubo othile futhi lutshele abafundi ukuthi bahlole ukusetshenziswa abakuhlosile. Ukufakwa ohlwini lwezinto ezithintana nokudla akuyona imvume ebanzi yokwengeza le nto ekudleni noma ukuyigwinya. Lezi zibonelo ziphathelene ne-United States; umdayisi osebenzela enye imakethe kufanele ahlonze izimfuneko ezisebenzayo zendawo leyo.
“Izinga labantu” kanye “nezinga lemithi” nawo adinga imininingwane ewasekelayo. Cela umdayisi asho izimfuneko ngegama futhi ahlonze indlela okuhloswe ukuthi umkhiqizo oqediwe ufakwe ngayo emzimbeni nesimo sawo sokugunyazwa ngokomthetho. Njengoba i-FDA ichaza ngokugunyazwa kwemikhiqizo, ukubhalisa isikhungo noma ukufaka umuthi ohlwini akufakazeli ngokwakho ukuthi ugunyaziwe. Isimangalo sekhwalithi naso asikwazi ukunquma ukuthi umuthi ufanele yini umuntu othile.
