Ngaba kukho umntu kusapho lwakho onengxaki yokunyakaza efana nesifo sikaParkinson? Okanye ngaba ugqirha wakho wakha wakuxelela okanye wakuxelela umntu omaziyo ngohlobo lwamayeza abizwa ngokuba yi-dopamine agonists? Eli gama lisenokuvakala liyinkimbinkimbi, kodwa ungakhathazeki. Namhlanje siza kuthetha ngalo ngendlela elula kakhulu onokuyiqonda. Funda oku ngokungathi uthetha nomhlobo.
Ngamafutshane, zithini ezi dopamine agonists?
Ukuze siqonde oku, masiqale sifunde kancinci ngendlela esebenza ngayo ingqondo yethu. Sineeseli kwinkqubo yethu yemithambo-luvo. Ezi seli zinxibelelana, okanye zithetha, omnye komnye ngeekhemikhali ezikhethekileyo. Ezi sizibiza ngokuba zii-neurotransmitters. Ezi zifana nabathunywa.
Khawucinge ukuba iseli yethu yemithambo-luvo ingumnyango onefudo. Ukuze ivule loo mnyango, ifuna isitshixo esifanelekileyo. Ngokufanayo, iseli nganye inento ebizwa ngokuba 'zii-receptors' kumphezulu wayo, njengefudo. Ii-neurotransmitters zifana nezitshixo ezifanela ezo fudo. Kanye njengokuba xa ufaka isitshixo, ifudo liyavuleka kwaye ucango luyavuleka, xa i-neurotransmitter iqhagamshela kwi-receptor, iseli iyasebenza.
I-Dopamine sisitshixo esibaluleke kakhulu kwingqondo yethu, i-neurotransmitter. Xa ufunda into ethile, xa uziva wonwabile kwaye wanelisekile, le dopamine yiyo edala ezo mvakalelo. Kwakhona, i-dopamine ibalulekile ukuze izihlunu zethu zihambe kakuhle.
Ngoku masingene kwisihloko sethu. Ngoobani abantu abasebenzisa i-Dopamine Agonists ? Ngamafutshane, la ngamayeza asebenza njenge-dopamine . Ngokwenyani, ayiyo-dopamine, kodwa iiseli zethu zengqondo ziyakhohliswa. Imilo yala mamolekyuli amachiza ifana kakhulu neemolekyuli ze-dopamine kangangokuba zingena ngqo kwii-receptors kwezo seli sizikhankanyileyo. Ngoko ke, xa uthatha eli yeza, liyavula iingcango ekufuneka zivulwe yi-dopamine. Ngamanye amazwi, la mayeza enza into efanayo ne-dopamine. Iiseli zethu aziwazi umahluko phakathi kwezi zimbini.
Ii-dopamine agonists ziikhemikhali ezibonakala ngathi yi-dopamine kwaye zenza into efanayo ne-dopamine, kodwa aziyiyo i-dopamine. Zifana nesitshixo esiphindwe kabini osisebenzisayo xa ulahlekelwa sisitshixo sokuqala.
Yintoni eyenziwa yi-dopamine emzimbeni wethu nakwimeko zonyango ezisebenzisa eli yeza?
I-Dopamine ayincedi nje kuphela ekushukumeni kwezihlunu. Ikwafuneka ukulawula ezinye iinkqubo ezibalulekileyo emizimbeni yethu. Umzekelo:
- Umsebenzi wentliziyo
- Umsebenzi wezintso
- Umsebenzi wePancreas
- Umsebenzi we-pituitary gland
- Inkqubo yethu ye-endocrine
- Inkqubo yokugaya ukutya
- Iinkqubo zokuzala zabasetyhini nabesilisa
Ngoko ke mhlawumbi ungaqonda ukuba zingaphi iingxaki ezinokuvela ukuba amanqanaba e-dopamine emzimbeni ayancipha. Ii-dopamine agonists zisetyenziselwa ukunyanga izifo ezininzi ezibangelwa kukungabikho kwe-dopamine.
Jonga itheyibhile engezantsi ukuze ubone ukuba zeziphi iintlobo zeemeko zonyango ezisetyenziswa kakhulu zezi mithi.

- Ukuba usebenzisa amanye amayeza athile: La mayeza awanakuthatyathwa ukuba usebenzisa amayeza abizwa ngokuba yi-'monoamine oxidase inhibitors' (ii-MAOI), ingakumbi lawo asetyenziselwa ukugula ngengqondo.
- Ukuba ukhe waba ne-psychosis ngaphambili: Aba bantu basengozini enkulu yokuphinda babe nezi mpawu xa besebenzisa la mayeza.
Yintoni umahluko phakathi kweDopamine kunye neDopamine Agonists?
Umntu angazibuza, ukuba i-dopamine iphantsi, kutheni i-dopamine ngokwayo ingenakunikwa ngqo njengeyeza, kwaye kutheni kunikwe iyeza elisebenza ngolu hlobo? Kukho izizathu ezahlukeneyo zoko.
1. Umqobo Wegazi: Ingqondo yethu ilumkile kakhulu. Ayivumeli yonke into esegazini ukuba ingene engqondweni. Inesihluzo esikhuselayo esibizwa ngokuba 'ngumqobo wegazi-ubuchopho'. Ifana 'nomlindi wokhuseleko' wengqondo. I-dopamine elawulwa ngaphandle ayinakudlula lo mlindi wokhuseleko iye engqondweni. Nangona kunjalo, ii-dopamine agonists zinokudlula lo mqobo zize ziye ngqo engqondweni.
2. Iziphumo ebezingalindelekanga: Xa i-dopamine inikwa ngqo njengenaliti, inokubangela iziphumo ebezingalindelekanga ezininzi kuba ichaphazela umzimba wonke. Ii-dopamine agonists zenzelwe ukusebenza ngendlela ejolise ngakumbi.
3. Ukusetyenziswa kwexesha elide:Kwisifo sikaParkinson, kunikwa iyeza elibizwa ngokuba yi-'Levodopa'. Liya engqondweni lize liguquke libe yi-dopamine. Kodwa ngokuhamba kwexesha, umthamo walo myeza kufuneka wonyuswe, kwaye emva koko iziphumo ebezingalindelekanga ziyanda. Ngoko ke, ngokusebenzisa ii-dopamine agonists kwizigaba zokuqala zesifo, kunokwenzeka ukulibazisa ukuqala kwe-levodopa. Oku kunceda isigulana sihlale siphilile ixesha elide.
