Qhov sib txawv tseem ceeb ntawm hydroquinone thiab hydrocortisone yog hydroquinone ua los ntawm kev txo qis melanin uas ua rau cov tawv nqaij tsaus, hos hydrocortisone ua rau hauv cov tawv nqaij los tiv thaiv kev tso tawm ntawm qee cov tshuaj hauv lub cev. uas tuaj yeem ua rau liab, khaus, thiab o.
Hydroquinone yog cov tshuaj tsw qab uas muaj cov tshuaj formula C6H4 (OH)2, thaum hydrocortisone yog cov tshuaj hormone cortisol uas siv los ua tshuaj.
Y Hydroquinone yog dab tsi?
YHydroquinone yog ib qho tshuaj tsw qab uas muaj cov tshuaj formula C6H4(OH)2. Nws yog hu ua benzene-1, 4-diol lossis quinol. Nws yog ib hom phenol thiab derivative ntawm benzene. Muaj ob pawg hydroxyl uas txuas rau lub nplhaib benzene (cov no tau sib koom ua ke hauv txoj haujlwm para).
Hydroquinone tshwm sim ua cov khoom siv dawb dawb. Muaj qee qhov kev hloov pauv ntawm qhov sib xyaw no uas tseem hu ua hydroquinones. Peb tuaj yeem tsim hydroquinone los ntawm ob txoj kev loj.
- Ib txheej txheem zoo ib yam li cov txheej txheem cumene uas cuam tshuam nrog kev dialkylation ntawm benzene nrog propene muab 1, 4-diisopropylbenzene. Cov tshuaj no ces reacts nrog huab cua, ua rau bis (hydroperoxide). Qhov sib xyaw ua ke no zoo ib yam li cumene hydroperoxide. Nws undergoes rearrangement nyob rau hauv acid los tsim acetone thiab hydroquinone.
- Hydroxylation ntawm phenol tshaj ib catalyst.
Muaj qee qhov chaw ntawm hydroquinone. Nws yog ib qho ntawm ob qho tseem ceeb reagents nyob rau hauv cov qog tiv thaiv nyob rau hauv bombardier beetles, nrog rau hydrogen peroxide.
Hydrocortisone yog dab tsi?
Hydrocortisone yog cov tshuaj hormone cortisol uas yog siv los ua tshuaj. Peb tuaj yeem siv cov tshuaj no los kho cov kab mob xws li adrenocortical insufficiency, ntshav siab calcium, thyroiditis, rheumatoid mob caj dab, dermatitis, hawb pob, thiab COPD. Txoj kev ntawm kev tswj hwm cov tshuaj no suav nrog kev tswj qhov ncauj, kev siv tshuaj pleev ib ce, lossis kev txhaj tshuaj. Cov npe lag luam tshaj plaws ntawm cov tshuaj no yog A-hydrocort, Cortef, Solucortef, thiab lwm yam.
Muaj qee qhov kev mob tshwm sim ntawm kev siv hydrocortisone, xws li kev pheej hmoo kis mob thiab edema. Tsis tas li ntawd, tuaj yeem ua rau muaj kev phiv mus ntev xws li pob txha pob txha, mob plab, lub cev tsis muaj zog, nqaij tawv, thiab candidiasis. Kev nyab xeeb ntawm kev siv nws thaum cev xeeb tub yog tsis meej.
hom kev ua ntawm hydrocortisone yog los ntawm kev ua haujlwm ua tus neeg sawv cev tiv thaiv kab mob thiab los ntawm kev tiv thaiv kab mob. Cov tshuaj no tau siv rau hauv xyoo 1941. Tshuaj, peb tuaj yeem muab nws lub npe hu ua pregnane steroid. Muaj ntau hom hydrocortisone esters hauv khw rau kev siv kho mob.
Los ntawm kev txhaj tshuaj, hydrocortisone yog siv los kho kev tsis haum tshuaj hnyav. Kev siv tshuaj pleev ib ce ntawm cov tshuaj no yog qhov tseem ceeb hauv kev kho eczema, ua xua pob, psoriasis, khaus, thiab mob tawv nqaij. Cov tshuaj no feem ntau muaj nyob rau hauv lub txee, tsis muaj tshuaj nyob rau hauv ntau lub teb chaws.
Qhov txawv ntawm Hydroquinone thiab Hydrocortisone yog dab tsi?
YHydroquinone yog ib qho tshuaj tsw qab uas muaj cov tshuaj formula C6H4(OH)2. Hydrocortisone yog cov tshuaj hormone cortisol uas yog siv los ua tshuaj. Qhov sib txawv tseem ceeb ntawm hydroquinone thiab hydrocortisone yog tias hydroquinone ua los ntawm kev txo qis melanin uas yog lub luag haujlwm rau qhov tsaus ntuj ntawm daim tawv nqaij, hos hydrocortisone ua rau hauv cov tawv nqaij los tiv thaiv kev tso tawm ntawm qee cov tshuaj hauv lub cev uas tuaj yeem ua rau liab, khaus, thiab o.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm hydroquinone thiab hydrocortisone hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Hydroquinone vs Hydrocortisone
Hydroquinones yog hydrocortisones uas yog cov tshuaj nrov rau cov tawv nqaij mob. Qhov sib txawv tseem ceeb ntawm hydroquinone thiab hydrocortisone yog tias hydroquinone ua los ntawm kev txo qis melanin uas yog lub luag haujlwm rau qhov tsaus ntuj ntawm daim tawv nqaij, hos hydrocortisone ua rau hauv cov tawv nqaij los tiv thaiv kev tso tawm ntawm qee cov tshuaj hauv lub cev uas tuaj yeem ua rau liab, khaus, thiab o.
