GCS - e tenei rongoā? Ko te mahi me te pānga o taero glucocorticosteroids
He pono ake kua rongo koutou o hormones pūtaiaki. To tatou tinana hua tonu ratou ki te whakahaere i ngā tukanga ora. I roto i tenei tuhinga, ka whakaaro matou glucocorticoids - hormones pūtaiaki, e kua whakaputaina i roto i te uho adrenal. Ahakoa he te nuinga o tatou hiahia i roto i o ratou analogues waihanga - GCS. He aha te mea rongoā? Hoki e whakamahia ratou me te aha te huru o te kino meinga ratou? Kia kite a.
mōhiohio General e pā ana ki GCS. He aha te mea rongoā?
To tatou rauropi synthesises hormones pūtaiaki pērā i glucocorticoids. E whakaputaina ratou i te uho adrenal, a kei te nuinga e pā ana ratou whakamahi ki te maimoatanga o te iti hoki adrenal. I tčnei wā, te whakamahi i kore anake glucocorticoids tūturu, engari ano hoki ratou analogues waihanga - GCS. He aha te mea rongoā? Hoki te tangata, te tikanga o enei analogs he rota, rite i runga i te tinana anti-inflammatory, immunosuppressive, antishock, pānga anti-mate pāwera.
Kua riro Glucocorticoids whakamahia rite taero (e whakahuatia ki roto i te tuhinga - PM) i roto i te 40-doma o XX rautau. Na roto i te mutunga o nga 30raa o te rau tau rua tekau, kua kitea kaipūtaiao pūhui taiki pūtaiaki i roto i te uho adrenal tangata, a i roto i te tau 1937 i tīpakohia e ia deoxycorticosterone mineralocorticoid. I roto i te wawe 40-doma i ahu mai glucocorticoid hydrocortisone me cortisone. i pera kanorau pānga pharmacological o cortisone, me te hydrocortisone, e i whakaritea e te reira ki te whakamahi ia ratou kia rite ki taero. I muri i te tahi mau wa, kua kawea kaiputaiao i to ratou kōtuitanga.
Ko te glucocorticoid tino kaha i roto i te rauropi tangata ko - cortisol (orotahi - hydrocortisone, tona utu - 100-150 moni), a kua whakaaro reira he nui. Ko reira taea hoki ki te tohatoha iti kaha: corticosterone, cortisone, 11-deoxycortisol, 11-dehydrocorticosterone.
O nga glucocorticoids taiao katoa rite whakamahi tarukino kitea hydrocortisone me cortisone anake. Heoi, i te pānga taha take whakamutunga atu pinepine atu i tetahi atu taiki, i te mea he aha i te wa nei tona whakamahi i roto i te rongoā he iti. Ki te rā, whakamahia anake glucocorticoid hydrocortisone ona hākawa (hydrocortisone hemisuccinate me hydrocortisone tāpia) ranei.
E pā ana glucocorticosteroids (glucocorticoids waihanga), lolotonga synthesized matou he maha o taua āpiha, i roto i nei te fluorinated (flumethasone, triamcinolone, betamethasone, dexamethasone, etc) ka kore-fluorinated (methylprednisolone, prednisolone, prednisone) glucocorticoids.
Taua āpiha kaha atu i to ratou ritenga māori, me e hiahiatia ana mo te maimoatanga o pota iti.
Ko te tikanga o te mahi o corticosteroids
e kore e matau tino te mahi o glucocorticoids i te taumata rāpoi. whakapono Scientists e ngāue enei taero i runga i ngā pūtau i te taumata o te ture o te tuhi ira.
Corticosteroids taunekeneke ki he hakari i roto i tata pūtau katoa o te tinana tangata receptors glucocorticoid intracellular. I roto i te ngaro o receptors taiaki (e he pūmua cytosolic) e taupāhohea noa. I roto i te āhua paruparu, he wahi o nga heterocomplexes, e ngā ano immunophilin, pūmua ru wera, me te pera atu ratou.
A, no te tomo steroids te pūtau (i roto i te membrane), herea ratou ki receptors me whakahohe matatini "glucocorticoid + receptor", i muri nei tomo te reira i te karihi pūtau me te taunekeneke ki te rohe DNA e kei roto i te ira kaiwhakatairanga kongakonga pūtaiaki hāngai (e huaina ana hoki e ratou glucocorticoid 'ka mea huānga). taea ki te whakahaere i (te tautāwhi ranei, hei kōrero, whakahohe) te tukanga o te te tuhi o etahi ira Complex "+ receptor glucocorticoid" ko. Ko tenei te mea arata'i ki pehanga whakaongaonga o mRNA ranei, me te he huringa i roto i te kōtuitui o ngā whākōkī me pūmua whakaritenga e takawaenga pānga pūtau.
whakaatu Various rangahau e tali te matatini "glucocorticoid + receptor" te ki ngā āhuatanga tuhi, hei tauira, pērā i take karihi Kappa B (NF-kB), ranei te activator o patohanga pūmua (AP-1) e whakahaere ira whai wāhi i roto i te whakautu ārai, me mumura (rāpoi adhesion, ira cytokine, protease me pera i runga i.).
Ko te pānga matua o GCS
He maha ngā pānga glucocorticoids i runga i te tinana tangata. Ēnei hormones i antitoxic, antishock, imunnodepressivnoe, antiallergic, mahi antiinflammatory me antiinflammatory. Kia tango o te titiro i te āhua o te mahi o corticosteroids.
- pānga Anti-inflammatory o corticosteroids. Meinga te pehanga o te mahi o te phospholipase te liberatiou 2. A, no te tāmia inhibition o tenei whākōkī i roto i te tinana tangata te (tuku) te inhibition o te waikawa arachidonic me te hanganga o te tahi mau kaitakawaenga inflammatory (pērā i prostaglandins, leukotrienes, me troboksan t. D.). Ano, te glucocorticosteroids fariiraa whakaiti inu exudation, vasoconstriction (whāiti) tōiti, whakapai ake o microcirculation i te mumura.
- pānga Anti-mate pāwera o GCS. puta te reira i rite ki te hua o te tukupu secretion me kōtuitui o kaiwhakaako o mate pāwera, whakaiti komuhumuhu basophils, inhibition o tuku histamine i basophils me ngā pūtau rewa sensitized, whakaiti i te maha o te B, me te lymphocytes T, te whakaiti te tūtohutanga o ngā pūtau ki nga kaiwhakaako o te mate pāwera, huringa whakautu ārai, me te pehanga o te antibody production.
- mahi Immunosuppressive o GCS. He aha te mea rongoā? Tenei te tikanga e te raau taero tautāwhi i immunogenez, pehi te hanga o paturopi. Corticosteroids tautāwhi i hekenga o wheua wheua pūtau kakau, tautāwhi i te mahi o te B, me te T lymphocytes tautāwhi i te tuku o cytokines i macrophages me leukocytes.
- Anti-paitini, me te pānga antishock o corticosteroids. Ko te pānga o hormones meinga e te pēhanga toto tiketike i roto i te tangata, kia rite ki te pai kia rite ki te faaitoitoraa o whākōkī ate whai wāhi i roto i te pākia o hautūāpōkere me endobiotikov.
- mahi Mineralocorticoid. Glucocorticosteroids i te kaha ki te faataere konutai me te wai i roto i te tinana, whakaongaonga te excretion o pāhare pāporo. e kore e rite pai rite hormones tūturu tenei whakakapi waihanga, engari ko te reira i te pānga i runga i te tinana i ratou.
Pharmacokinetics
Hoki te roanga o te mahi o steroids pūnahanaha taea te wehea ki:
- Glucocorticosteroids mahi poto (hei tauira, hydrocortisone, te utu o e rerekē i 100 ki te 150 moni).
- Glucocorticosteroids ki te roanga toharite o te mahi (prednisolone (urupare e kore he tino pai i), methylprednisolone).
- Glucocorticosteroids ki te mahi auroa (triamcinolone acetonide, dexamethasone, betamethasone).
Ko e kore anake hoki e takoto ai te roanga o glucocorticosteroids. kia hoki kia Whakarōpū o ratou te aratau o whakahaere:
- waha;
- intranasal;
- glucocorticosteroids hau.
Tenei whakarōpūtanga, Heoi, pā anake ki glucocorticosteroids pūnaha.
He te tahi mau raau taero i roto i te puka o hinu me aihikirīmi (corticosteroids rohe). Hei tauira, "Afloderm". He pai Reviews o taua formulations.
Kia titiro a i ngā momo o corticosteroids pūnahanaha anake.
steroids Oral tino whenumi i roto i te whēkau, kahore ai raruraru. Tino herea ki pūmua i roto i te wē (transcortin, albumin). tae te kukū mōrahi o corticosteroids waha i roto i te toto e i muri i 1.5 haora i muri i whakahaere. mamae ratou biotransformation i te ate, tākihi (wāhanga) me ētahi atu te kopa i conjugation ki glucuronide pūkawa ranei.
Tata 70% o te GCS conjugated excreted i te mimi, tetahi 20% i roto i te feces ka tohu i muri, me te toenga - ki ētahi atu fluids koiora (hei tauira, i muri mai). Ko te hawhe - i te 2 ki te 4 haora.
Ka taea e koe te hanga i tētahi ripanga iti ki te tawhā pharmacokinetic o corticosteroids-waha.
