Kana uri amai vane pamuviri, amai vanoyamwisa, kana mumwe munhu ari kutarisira mwana, pamwe wakambonzwa zita rekuti "prolactin". Iri ihormone inokosha kwazvo mumuviri wedu, kunyanya kuvakadzi, iyo inobatanidzwa muzvinhu zvakawanda, zvakaita sekubereka uye kugadzirwa kwemukaka wezamu. Saka ngatitaure nezvazvo zviri nyore uye zvine hunhu nhasi.
Zvichitaurwa zviri nyore, chii chinonzi prolactin?
Funga nezvemuviri wedu sefekitori hombe ine nyanzvi dzebasa rega rega. Mahormone ndiwo anotumira mashoko ekuti fekitori iyi irambe ichishanda zvakanaka. Prolactin , inozivikanwawo seLactotropin kana PRL, ndeimwe yenhume dzakakosha kudaro.
Kunyange zvazvo homoni iyi ichibatanidzwa mumazana emabasa mumuviri wedu, ine mabasa maviri makuru:
1. Kubatsira mukugadzirwa kwemukaka wemuzamu (Lactation): Chikonzero chikuru chinoita kuti amai vagone kugadzira mukaka wemwana wavo ihormone inonzi prolactin.
2. Inobatsira pakukura kwemazamu: Hormone iyi ndiyo inoita kuti mazamu anogadzira mukaka mumazamu, kunyanya panguva yekuzvitakura, uye iagadzirire kuyamwisa.
Zvichitaurwa zviri nyore, ndiyo iyi prolactin hormone inorayira miviri yedu kuti igadzire chipo chinokosha zvikuru chinonzi "mukaka wezamu" chinodiwa kuti mwana agutse nzara yake mushure mekubereka mwana.
Homoni iyi inonzi Prolactin inobva kupi? Inoshanda sei?
Pasi pehuropi hwedu, pane gland diki asi rine simba rakakura sepizi diki rinonzi Pituitary Gland . Rakafanana ne "nzvimbo yekudzora" yehurongwa hwemahormone emuviri wedu. Kubva muimba iyi yekudzora ndipo panogadzirwa prolactin yakawanda uye inoburitswa muropa.
Asi izvi hazvingoitiki chete. Kune nyanzvi mbiri dzinodzora pituitary gland, dzichiiudza kuti igadzire prolactin uye dzichiiudza kuti irege kuigadzira.
- Dopamine: Iyi ineurotransmitter muuropi hwedu. Dopamine inoshanda nekuderedza kugadzirwa kweprolactin. Kureva kuti, dopamine inodzivisa prolactin kuwedzera zvakanyanya.
- Estrogen: Iri ihomoni revakadzi rinokosha. Estrogen inobatsira kuwedzera kugadzirwa kweprolactin.
Sezvo huwandu hweestrogen huchiwedzera panguva yekuzvitakura, kugadzirwa kweprolactin kunowedzerawo. Izvi zvinoita kuti matumbu anogadzira mukaka (mammary alveoli) ari mumazamu akure uye agadzirire kugadzira mukaka wemwana.
Chinoshamisa ndechekuti mushure mekunge mwana aberekwa, mwana paanoyamwa zamu raamai, meseji iyoyo inoenda zvakananga kuuropi uye inoudza pituitary gland kuti "igadzire prolactin yakawanda." Sezvo prolactin ichiwedzera, mukaka wakawanda unogadzirwa. Tinoti izvi i "positive feedback loop".Kureva kuti, kana maitiro acho atanga, anowedzera kukurudzira maitiro iwayo.
Sei huwandu hweprolactin huchichinja kamwe kamwe?
Huwandu hweprolactin hahuna kufanana nguva dzose. Dzimwe nguva hunowanda zvega, uye dzimwe nguva hunowanda nekuda kwechirwere.
Mamiriro ezvinhu apo huwandu hweProlactin hunowedzera zvechisikigo
Zvinhu izvi zvinogona kukonzera kuti huwandu hweprolactin yako hukwire kwenguva pfupi, zvichireva kuti kwenguva pfupi chete. Izvi zvakajairika uye hapana chekunetseka nazvo.
- Kushushikana kwemuviri: Paunonzwa kurwadziwa kwakanyanya.
- Kurovedza muviri: Mushure mekurovedza muviri kwakanaka.
- Kudya: Mushure mekudya.
- Kusangana pabonde: Mushure mekuita zvepabonde.
- Kukurudzira mazamu: Kana mazamu akakurudzirwa kunze kwekuyamwisa.
- Kukuvara pachipfuva: Kana paine tsaona kana kukuvara kwechipfuva.
- Kubata pamuviri nekuyamwisa: Mwero weprolactin wakakwira zvakanyanya munguva idzi.
Mazinga eprolactin akakwira zvisingawanzoitiki (Hyperprolactinemia)
Mamwe matambudziko ehutano kana mishonga zvinogona kukonzera kuti huwandu hweprolactin hurambe hwakakwira zvisina kujairika kwenguva yakareba. Chirwere ichi chinozivikanwa se hyperprolactinemia .
Chikonzero chikuru cheizvi chirwere chinonzi prolactinoma . Iri ibundu diki, risiri rekenza (kazhinji) rinokura mugland repituitary. Bundu iri rinoburitsa hormone yeprolactin zvisina kufanira.
Kana huwandu hweprolactin hwakwira zvisina kujairika, zviratidzo zvinotevera zvinogona kuitika.
| Chiratidzo | Ndiani akanganiswa uye tsananguro iri nyore |
|---|---|
| Kusabereka | Zvinogona kukanganisa vakadzi nevarume. Kana huwandu hweprolactin hukawedzera, zvinokanganisa ovulation uye kugadzirwa kwembeu. |
| Kuenda kumwedzi kwemwedzi kusingaenderane | Zvinokanganisa vakadzi. Kuenda kumwedzi kunogona kusaenderana nenguva, kunonoka, kana kumira zvachose. |
| Kubuda kwemukaka kubva mumazamu (Galactorrhea) | Dambudziko iri rinogona kuitika kumukadzi kana murume asina pamuviri kana kuyamwisa. |
| Kuderera kwechido chepabonde | Zvakajairika kune vakadzi nevarume. |
| Kusashanda zvakanaka kwenhengo dzesikarudzi | Zvinokanganisa varume. |
Mazinga eprolactin anogona kuderera zvakanyanya here?
Ehe, zvinogona kuitika. Asi hazviwanzoitiki. Kazhinji, kunze kwekunge uri nepamuviri kana kuti uchiyamwisa, huwandu hweprolactin yako hunenge hwakaderera. Ihwohwo hutano hwakanaka.
Saka, chiratidzo chega chekuti huwandu hweprolactin hwakaderera zvakanyanya kusagadzirwa kwemukaka wemuzamu mushure mekubereka mwana .
Muchiitiko ichi, chikonzero chingave chirwere chinonzi hypopituitarism . Izvi zvinoreva kuti pituitary gland haigadzi rimwe kana akawanda emahormone anodiwa. Ichi chirwere chisingawanzoitiki.
Asi unofanirawo kurangarira izvi. Kuderera kweprolactin hakusi iko kwega chikonzero chinoita kuti amai vasave nemukaka mudiki. Pane zvimwe zvinhu zvakawanda zvinogona kukonzera izvi. Saka, kana uine matambudziko ekuyamwisa, zvakanaka kuona nyanzvi kana nyanzvi yekuyamwisa nezvazvo.
Unoyera sei mazinga ako eProlactin?
Izvi zviri nyore kwazvo. Chiremba wako anogona kuraira kuongororwa ropa (PRL test) kuti aone huwandu hweprolactin muropa rako. Izvi zvakafanana nekuongororwa ropa nguva dzose. Kana uine zviratidzo zvataurwa pamusoro apa uye uchifungidzira kuti pituitary gland yako iri kushanda zvakanaka, chiremba wako acharaira bvunzo iyi.
Ndezvipi mazinga eprolactin akajairika?
Tafura iri pazasi inoratidza huwandu hweprolactin hwakajairika mumunhu ane hutano. Zvisinei, hunhu uhwu hunogona kusiyana zvishoma kubva murabhoritari kuenda kune imwe. Saka, zvakakosha kutarisa chikamu che "Normal Range" chemushumo wako.
| Chikamu | Kukosha kwakajairika (ng/mL) |
|---|---|
| Varume | Zvisingasviki 20 ng/mL |
| Vakadzi vasina pamuviri uye vasina kuyamwisa | Zvisingasviki 25 ng/mL |
| Vakadzi vane pamuviri kana kuti vanoyamwisa | Pakati pe80 ne400 ng/mL |
Kana muine zvinokunetsai nezvemigumisiro yenyu, musazeza kutaura nachiremba wenyu nezvazvo.
Unofanira kuona chiremba rini nezve prolactin?
Kana uchifunga kuti une chimwe chezviratidzo zvehuwandu hweprolactin hwatakakurukura pamusoro apa (sekuenda kumwedzi kusina kurongeka, kushaya mbereko, uye kubuda ropa rakaita semukaka mumazamu ako), shanyira chiremba wako nekukasika . Anogona kuita bvunzo, kuwana chikonzero, uye kunyora mushonga kana zvichidikanwa.
Kana uri amai vanoyamwisa uye uine dambudziko remukaka usina kukwana, tsvagawo rubatsiro rwechiremba nezvazvo.
Prolactin ihormone inokosha pakubata pamuviri nekuyamwisa. Asi kunze kweizvozvo, hatifungi zvakawanda nezvazvo kusvika zviratidzo zvisingawanzoonekwi zvaonekwa. Saka ziva nezvekuchinja kuri kuitika mumuviri wako. Kana uine zvinokunetsa, tsvaga rubatsiro rwechiremba.
Mharidzo Yekuenda Nayo Kumba
- Prolactin ihormone inonyanya kukosha pakugadzirwa kwemukaka wemuzamu uye kukura kwezamu.
- Hormone iyi inogadzirwa negland repituitary riri muuropi.
- Mazinga eprolactin anowedzera panguva yekuzvitakura nekuyamwisa.
- Kuwanda kweprolactin (Hyperprolactinemia) kunogona kukonzera matambudziko akadai sekushaya mbereko uye kunonoka kwekuenda kumwedzi.
- Kana uine zviratidzo zvakaita seizvi, usavhunduka uye bvunza chiremba wako nekukasika kuti akupe mazano.
