Amabakala emethylene blue: intsingiselo yebakala lobugcisa, lereajenti, le-akwariyam, nele-USP
Ilebhile yemethylene blue inokuchaza izinto ezintathu ezahlukeneyo: iinkcukacha ezimiselweyo ezihlangatyezwa yinto leyo, indlela equlunqwe ngayo into esebhotileni, okanye ukusetyenziswa okujoliswe kuko ngumthengisi. Lo mahluko ugqiba ukuba yintoni onokuyiqonda ngokufanelekileyo kumagama afana nelobugcisa, ireajenti yelabhoratri, i-akwariyam, kunye ne-USP.
La magama awenzi uluhlu olunokuthenjwa olusuka kumgangatho ophantsi luye kophezulu. Imveliso inokuchazwa kakuhle ukuze ifanele ukufaka umbala kwisampulu ngaphandle kokuba yenziwe njengeyeza. Isisombululo se-akwariyam sinokuba nenkcazelo ecacileyo yezinto ezikuso ngaphandle kokuba loo nto iqinisekisa ukuba sikulungele ukutyiwa okanye ukuselwa ngabantu. Qala ngokuchonga uhlobo lwebango olwenziwa yilebhile nganye.
Ukuthelekisa iintsingiselo zeelebhile
Le theyibhile yahlula ibango kubungqina obufunekayo ukuze livavanywe. Imizekelo ibonisa iindidi, kungekhona iingcebiso zokuthenga.
| Ilebhile | Ikuxelela ntoni | Umzekelo okanye iinkcukacha ezimiselweyo ezisebenzayo | Into engayiqinisekisiyo |
|---|---|---|---|
| Ibakala lobugcisa | Udidi lomthengisi oludla ngokunxulunyaniswa nemveliso okanye nomsebenzi welabhoratri oneemfuno ezingqongqo kangako | UFisher ubeka iimveliso zobugcisa, ezelabhoratri, kunye neereajenti phantsi komgangatho ochazwa ngumthengisi apho kungekho mgangatho osemthethweni uchaziweyo | Ipesenti yovavanyo lobungakanani esebenza kuyo yonke imveliso, inkcazelo yezinto ezingcolisayo, okanye ukufaneleka kokuginywa |
| Ireajenti yelabhoratri | Ikhemikhali enikezelwa ngenjongo yomsebenzi welabhoratri; ibango elichanekileyo lomgangatho kufuneka licaciswe | Iinkcukacha zemveliso zomthengisi nesatifikethi sebhetshi kufuneka zichaze imida efanelekileyo | Ukuthobela ngokuzenzekelayo i-ACS okanye incwadi esemthethweni yemigangatho yamayeza |
| Ireajenti ye-ACS | Ibango lokuthobela iinkcukacha ezimiselweyo zereajenti ezisebenzayo ze-American Chemical Society | I-ACS Reagent Chemicals iqulethe iimfuno zococeko ezikhethekileyo kwikhemikhali nganye kunye neendlela zokuhlalutya | Ukufaneleka kwemveliso epakishiweyo njengeyeza labantu |

Umahluko weelabhoratri ulandela iinkcazelo ezipapashiweyo zikaFisher zamabakala eekhemikhali kunye nenkcazelo ye-ACS yeenkcukacha ezimiselweyo zeereajenti zayo. Imizekelo yeemveliso nemithetho yolawulo ixoxwa ngezantsi.
Iilebhile zelabhoratri zichaza ukufaneleka komsebenzi othile
“Ibakala lereajenti yelabhoratri” lulwazi olungaphelelanga ngaphandle kokuba umthengisi uchaza iimvavanyo ezixhasa elo gama. Ilabhoratri inokufuna idayi efaka umbala kwiibhaktheriya ngokungaguquguqukiyo, ireajenti enamanqanaba alawulwayo ezinyithi ezikhoyo ngezixa ezincinane kakhulu, okanye into efanele uhlalutyo lobungakanani. Ezo mfuno ziyangqamana, kodwa azifani ncam.
Njengomzekelo othile, imethylene blue yeSigma-Aldrich M9140 idweliswe njengomgubo oqinisekiswe yiBiological Stain Commission, onomxholo wedayi ubuncinane oyi-82%, kunye nokusetyenziswa kokufaka umbala kwiisampulu. Leyo yinkcazelo yemveliso ejoliswe ekusetyenzisweni okuthile. Ayithethi ukuba ipesenti eseleyo yenziwe zizinto ezingcolisayo ezinetyhefu, kwaye ayilobango lokusetyenziswa ekwenzeni amayeza.
Ipesenti ifuna inkcazelo. Umxholo wedayi, ucoceko olulinganiswa ngekhromatografi, kunye novavanyo lobungakanani olulungiswe ukuze kuthathelwe ingqalelo amanzi, yimilinganiselo eyahlukeneyo. Ngoko ke ukuthelekisa elona nani likhulu kwiinkcazelo ezimbini kunokuba kukuthelekisa iimpawu ezahlukeneyo. Buza ukuba kulinganiswe ntoni, ngeyiphi indlela, kwaye ngokwasiphi isiseko ngaphambi kokubeka enye imveliso ngaphezu kwenye.
Ukusetyenziswa kwi-akwariyam akulobakala lococeko elisebenza kuyo yonke imveliso
Ulwazi lwemveliso yemethylene blue kaKordon lunika umzekelo oluncedo welebhile yokusetyenziswa okujoliswe kuko ekhatshwa ziinkcukacha ezimiselweyo. Luchaza ityuwa yechloride engenazinki kwisisombululo samanzi se-2.303%, luchonga ukusetyenziswa kwi-akwariyam, kwaye luchaza ngokucacileyo ukuba ayifanele kutyiwa okanye kuselwe ngabantu. Lukwachaza ukuba ayifanele kusetyenziswa njengeyeza leentlanzi ezilungiselelwe ukutyiwa.
Igama elithi i-akwariyam likuxelela ukusetyenziswa. Uxinaniso lukuxelela ukomelela komxube. Ukungabikho kwezinki kuchaza uphawu olunye lwento leyo. Akukho nanye kwezi nkcazelo enika iinkcukacha ezipheleleyo ezimiselweyo zemveliso yamayeza.
Ngokufanayo, akukho sizathu sokucinga ukuba yonke ibhotile ye-akwariyam iqulethe isinyithi esinzima okanye isongezelelo esithile. Qinisekisa izinto ezikule mveliso kanye. Musa ukutshintsha ubungqina obungekhoyo ngokunika isiqinisekiso okanye ngokwenza isityholo. Kwizigqibo eziphathelele iintlanzi, sebenzisa isikhokelo esahlukileyo semethylene blue yeentlanzi ze-akwariyam.
Yintoni efunekayo ukuxhasa ibango le-USP
Umboniso wesicatshulwa se-USP Methylene Blue uchaza into leyo kwaye unika uluhlu lovavanyo lobungakanani lwe-97.0–103.0%, olubalwa ngokwento eyomisiweyo. Umda ophezulu ngumda wokwamkelwa kweziphumo zohlalutyo, kungekhona ibango lokuba ibhotile inokuqulatha into engaphezulu kwe-100%. Ukuchazwa kokubalwa ngokwento eyomisiweyo nako kubalulekile xa kuthelekiswa into enamanzi abotshelelwe kuyo kunye nesiphumo somxholo wedayi njengoko inikezelwe.
Lo mboniso awusiso isicatshulwa esipheleleyo. Isiphumo esinye sovavanyo lobungakanani esiphumeleleyo asinakuqinisekisa ukuba zonke iimfuno ezisebenzayo zihlangatyeziwe. Buza ukuba loluphi uhlelo okanye zeziphi iinkcukacha ezimiselweyo ebezisebenza ezisetyenzisiweyo, uze ucele amaxwebhu anxulumene nebhetshi enikezelweyo. Inkcazelo eyahlukileyo yemethylene blue yebakala le-USP iwucacisa ngakumbi lo mahluko.
Kwakhona chonga ukuba ibango libhekisela entwenini. “Yenziwe ngemethylene blue yebakala le-USP” ibhekisela kwisithako. Ukunyibilikisa eso sithako, ukusifaka kwizikhongozeli, kunye nokusigcina kudala imibuzo eyongezelelekileyo ngemveliso egqityiweyo, kuquka uxinaniso, ezinye izithako, ulawulo longcoliseko, ukupakishwa, kunye nozinzo.
Ilebhile yemveliso yeyeza icace ngakumbi. Ilebhile yeProvayBlue ka-2024 egcinwe yi-FDA ichaza isisombululo esingenazintsholongwane sokufakwa emthanjeni esiqulethe imethylene blue eyi-5 mg/mL kunye namanzi enaliti, amandla aso echazwe ngokohlobo lwetrihydrate. Ezi ziinkcukacha zemveliso nendlela yokuyisebenzisa. Ibango lesithako se-USP esithengiswa ezivenkileni aliziniki ezo nkcukacha.
Kutheni amagama athi ibakala lokutya nelokusetyenziswa ngabantu efuna ukuhlolisiswa
Ibakala lokutya kufuneka likhokelele kumgangatho othile nasekusetyenzisweni okuvumelekileyo ekutyeni, kungekhona kwinkolelo ngokubanzi yokuba ikhemikhali eluhlaza okwesibhakabhaka iyatyiwa. Isishwankathelo se-FDA sezongezelelo zombala ezivumelekileyo asiyidwelisi imethylene blue njengombala ovunyiweyo wokutya kwabantu. Ukuvunywa kudidi olunye okanye ekusetyenzisweni okuthile akunakudluliselwa kolunye.
Kukho omnye umgibe kwiziphumo zokukhangela: imethylene blue iyavela kuluhlu lwe-FDA lwezinto ezidibana nokutya, olubhekisa kummiselo othile kwaye luxelela abafundi ukuba bahlole ukusetyenziswa abajolise kuko. Ukudweliswa kwento edibana nokutya akuyomvume ngokubanzi yokongeza loo nto ekutyeni okanye yokuyiginya. Le mizekelo iphathelele eUnited States; umthengisi osebenzela enye imarike kufuneka achonge iimfuno ezisebenzayo zaloo ndawo iphantsi kolawulo lomthetho.
“Ibakala lokusetyenziswa ngabantu” kunye “nebakala lokwenziwa kwamayeza” nawo afuna iinkcukacha eziwaxhasayo. Cela umthengisi achaze iinkcukacha ezimiselweyo ngegama aze achonge indlela ekujoliswe kuyo yokusebenzisa imveliso egqityiweyo kunye nobume bayo ngokwemithetho yolawulo. Njengoko i-FDA ichaza ngokuvunywa kweemveliso, ukubhalisa indawo yemveliso okanye ukudwelisa iyeza akukuqinisekisi ngokwako ukuvunywa. Ibango lomgangatho nalo alinakugqiba ukuba iyeza limfanele na umntu othile.
