I-hormone ye-Steroid yinto enezinto zomzimba. Emzimbeni badlala indima ebalulekileyo. IiHormone zinoxanduva lokulawula ezininzi iinkqubo zobomi ezibalulekileyo kumzimba. Umzimba onempilo uvelisa ezi zinto ngokuzimela. Kodwa ngamanye amaxesha ngenxa yeengxaki zempilo ukugcina i-hormone ye-steroid kwisigqabileyo iyadingeka ngoncedo lweziyobisi zamachiza.
Uluhlu lwamachiza ngama hormone e-steroid
Eli qela lezinto ziquka i-corticosteroids kunye nama-hormone wesini. Emzimbeni, benza imisebenzi enjengomgaqo wolawulo lwe-metabolism nokukhula. I-hormone ye-steroid enoxanduva lokuqinisekisa imisebenzi yokuzala yomzimba.
Iimpawu kwi-correnx ye-adrenal ziveliswa. IHormones inokufumaneka kwi-drops yamapayipi e-cytoplasm. Ngenxa yokwandisa i-lipophilicity, izinto zingena kalula kwiimbumba zibe ngegazi, kwaye zivela apho zihamba ngendlela eya kwiiseli ezithathwa ngumzimba njengokuba ziyingozi.
Emzimbeni womntu, akukho ndlela ekhethekileyo, apho i-hormone ye-steroid iqokelela khona, ngoko, emva kokutshatyalaliswa kwezinto, ziyasuswa emzimbeni. Yonke into ehleliyo i-precursors ye-hormone ngendlela ye-cholesterol ester kwiiseli ezivelisa i-steroids. Kwaye ukuhlanganiswa kwe-hormone ye-steroid, i-hormone peptide-izinto eziveliswa yi-pituitary gland kunye ne-hypothalamus.
Emzimbeni womntu ngamnye kukho iintlobo ezintandathu eziphambili ze-hormone ze-steroid:
- cortisol;
- estradiol;
- i-calcitriol (ngaphambili - calcifolol);
- testosterone;
- progesterone;
- aldosterone.
Amacangca amacandelo amaninzi kwezi zinto afutshane-aquka kuphela iibhanki ze-carbon. Akukho mahomoni asemacaleni. Futhi kuphela i-calcitriol isakhiwo esincinane okanye esincinane.
Ukuba abafazi banokuphazanyiswa kwi-hormone ye-steroid, bachongwa ngamachiza akhethekileyo. Izidakamizwa ezidumileyo ezenza i-hormone ye-steroid emzimbeni yile:
- Hydrocortisone ;
- Dexamethasone;
- Cortisone;
- Estriol;
- Prednisone;
- Prednisolone.
Kungekudala, i-hormone yokwenziwa kwe-steroid isetyenziswe ngabafazi ngokuphindaphindiweyo. Iziyobisi zisetyenziswa ngokuthe ngqo ekuphatheni izifo ezahlukahlukeneyo kwaye zigcine impilo enempilo jikelele.

Imiphumo emibi kunye nokuchasene nokusetyenziswa, mhlawumbi, nangona mayeza amaninzi. Kodwa xa kuziwa kuma-hormone, kufuneka uqaphele ngakumbi. Okokuqala, ezi zinto zingakhokelela kwezinye iinguqu ezingathandekiyo. Okwesibini, ukuba uxhatshaza amahomoni, umzimba uya kuyeka ukuzenzela wona, oya kuthi umzimba uya kuba mnandi kakhulu.
Ukusetyenziswa okungalawulwayo kweziyobisi nge-hormone ye-steroid ixutywe ngeengxaki ezilandelayo:
- ukutshabalaliswa kwesibindi;
- ukubonakala kwentsimbi ;
- izifo zesimo senhliziyo;
- ukuphulwa komsebenzi wengqondo evamile;
- kunyusa uxinzelelo lwegazi;
- ukwakheka kwegazi;
- ukwanda kwamazinga e-cholesterol yegazi;
- ukuphazamiseka kwengqondo.
Iingqinisiso eziphambili zokuthatha i-hormone ye-steroid zezi:
- Akukhuthazwa ukuba yamkele imali kubantu abatsha.
- Amahomoni angenayo i-steroid ayichaphazela impilo yabantu abaphethwe zizifo zentliziyo, iintso kunye nesibindi.
- Ukungafuni ukuthatha amayeza kufuneka kubekho phambi kwezicubu ezintle nezibi.
