Reka twige gusa ibyerekeye Anterior Pituitary Gland (Adenohypophysis): umutegetsi muto mu bwonko bwacu!

Ese wigeze wibaza ukuntu agace gato k'umubiri wacu gakora akazi kangana iki? Ahantu hamwe hatangaje ni agace k'imbere k'ubwonko (anterior pituitary gland) tugiye kuvugaho uyu munsi. Hari n'abandi bayita "Adenohypophysis". Kimwe n'umuyobozi w'itsinda ry'abaririmbyi, aka gace gashinzwe gukora no kurekura imisemburo igenzura imirimo myinshi y'ingenzi y'umubiri.

None se, iyi gland y'imbere ya pituitary ni iki?

Mu magambo make, iki ni igice cy'imbere cy'agace ka pituitary. Agace ka pituitary ni agace gato kangana n'agashaza, gaherereye mu nsi y'ubwonko bwawe, munsi gato ya hypothalamus. Iki ni igice cy'urusobe rw'imisemburo yawe. Ni ukuvuga igice kigenzura imikorere y'uturemangingo dutandukanye mu mubiri.

Tekereza ko agace ka pituitary kawe gafite ibice bibiri: agace k'imbere (ni ko gace k'imbere k'ubwonko tuvuga uyu munsi) n'agace k'inyuma. Aka gace k'imbere ni ko gakora imisemburo itandatu (6) kakayirekura mu mubiri. Iyi misemburo ni yo umubiri wacu ukoresha:

• Gukura (turakura)
• Metabolism (ingufu zikorwa n'umubiri, gutwika ibintu)
• Uburumbuke (ubushobozi bwo kubyara)
• Gusubiza ku muhangayiko
• Konsa (ku babyeyi)

Ibintu byinshi by'ingenzi biragenzurwa. Nubwo ari muto, ni umuntu uhugiye cyane kandi ufite imbaraga!

None se, ni iyihe misemburo yihariye ikorwa n'agace k'imbere k'ubwonko ka pituitary?

Hari imisemburo itandatu y'ingenzi igize uyu muyobozi muto. Reka turebe icyo ari cyo n'icyo ikora.

1. Hormone ya Adrenocorticotropic (ACTH): Iyi ni yo ituma adrenal glands ikora cortisol, izwi kandi nka "hormone ya stress," n'indi misemburo. Ibi ni ingenzi cyane mu bihe byihutirwa, nko mu gihe ufite ubwoba.

2. Imisemburo itera imbaraga mu gutera intanga (FSH): Ku bagabo, itera imbaraga mu gutera intanga ngore kugira ngo ikore intanga. Ku bagore, itera imbaraga mu gutera intanga ngore kugira ngo ikure, ikayitegura kugira ngo ikore intanga ngore, kandi ikarema imisemburo ya estrogen.

3. Hormone ya Luteinizing (LH): Niba uri umugore, LH itera imbaraga intanga ngore kugira ngo ikore progesterone. Niba uri umugabo, itera imbaraga ikorwa rya testosterone.

4. Imisemburo y'ubukure bw'umuntu (HGH): Iyi ni ingenzi mu mikurire y'abana bato. Ibafasha gukura barerure no kugira umubiri umeze nk'imitsi. Ku bantu bakuru, ifasha mu kubungabunga imitsi n'amagufwa, kandi igira ingaruka ku buryo ibinure byo mu mubiri bibikwa.

5. Prolactine:Iyi misemburo ituma umubyeyi abyara umwana abyara. Ishobora kandi kugira ingaruka ku mihango, ku burumbuke (ubushobozi bwo kubyara), ndetse no ku mikorere y'imibonano mpuzabitsina.

6. Imisemburo itera imbaraga mu mikorere ya tiroyide (TSH): Iyi ni yo ibwira tiroyide gukora no kurekura imisemburo yayo. Imisemburo ya tiroyide ni ingenzi mu kubungabunga umuvuduko w'imikorere y'umubiri wacu.

Urabona, hari imirimo myinshi itandukanye ishobora gukorwa muri aka gace gato!

Ni gute agahu k'imbere k'ubwonko gakorana n'izindi ngingo?

Ingirabuzimafatizo yawe y'imbere ya pituitary ifitanye isano itaziguye n'igice cy'ubwonko bwawe cyitwa hypothalamus. Hypothalamus irekura "imisemburo irekura" na "imisemburo ibuza" nka somatostatin na dopamine mu maraso binyuze mu muyoboro wa pituitary (igice gito kimeze nk'umuyoboro uhuza ubwonko n'ingirabuzimafatizo ya pituitary). Iyi misemburo irekura itera imbaraga cyangwa ikabuza ikorwa ry'imisemburo n'ingirabuzimafatizo ya pituitary y'imbere. Hypothalamus n'ingirabuzimafatizo ya pituitary y'imbere ni nk'abantu babiri bahora bavugana kandi bagahana amakuru.

Iyo imisemburo ivuye mu gasabo k'imbere k'ubwonko (anterior pituitary gland), ikorana kandi ikagira ingaruka ku zindi ngingo nyinshi, imyakura, n'ingingo mu mubiri wacu. Urugero:

• Amagufwa yacu, imitsi, n'izindi ngingo z'imbere
• Ingirabuzimafatizo z'intanga ngabo
• Indwara ya Tiroyide
• Intanga n'udusabo tw'intanga (ni ukuvuga imyakura y'imyororokere)
• Imyakura y'amabere (imyakura ikora amata)

Iyi gland y'imbere ya pituitary iherereye he neza neza?

Nkuko twabivuze mbere, agahu k'ubwonko kawe gaherereye mu nsi y'ubwonko bwawe, inyuma y'ikiraro cy'izuru ryawe, munsi gato ya "Hypothalamus." Gaherereye mu cyumba gito, cyangwa agafuka, mu igufwa riri mu gahanga kawe ryitwa igufwa rya sphenoid. Abaganga babyita "Sella Turcica."

Ingirabuzimafatizo yawe ya pituitary ifite utubuto tubiri dufatanye. Ingirabuzimafatizo y'imbere ya pituitary iherereye imbere, ireba imbere y'umutwe wawe. Ingirabuzimafatizo y'inyuma ya pituitary iherereye inyuma. Ariko igitangaje ni uko ingirabuzimafatizo y'imbere ya pituitary ari nini kurusha iy'inyuma. Hafi 80% by'uburemere bw'ingirabuzimafatizo yose ya pituitary iri muri iki gice cy'imbere.

Ni ibihe bibazo bishobora kubaho ku gasabo k'imbere k'umusonga w'imbere w'ubwonko?

Kubera ko iyi ngirabuzimafatizo ikora imisemburo myinshi y'ingenzi, ibibazo iyo ari yo yose ifitanye isano na yo bishobora gutera ibibazo bitandukanye by'ubuzima. Muri rusange ibi bibazo bishobora kugabanywamo ibyiciro bibiri:

1. Hypopituitarism: Ibi bivuze ko ingirabuzimafatizo ya pituitary ikora imisemburo mike ugereranyije n'ibikenewe.

2. Hyperpituitarisme:Ibyo bivuze ko imisemburo ya pituitary ikora imisemburo myinshi kuruta uko bikenewe.

Hari impamvu nyinshi z'ingenzi zituma ibi bintu bibiri bikunze kubaho:

• Ibibyimba byo mu gasabo k'ubwonko (adenomas): Ibi akenshi ni ibibyimba bitari kanseri (bitari bibi).
• Kwangirika kw'agahu k'imbere k'ubwonko bwa pituitary, hypothalamus, cyangwa umuyoboro wa pituitary: Ibi bishobora guterwa n'impanuka, kwandura, cyangwa kuva amaraso (urugero: impyiko y'ubwonko bwa pituitary).
• Indwara za genetiki: Urugero, indwara nka `(Multiple Endocrine Neoplasia - MEN)`.

Zimwe mu ndwara ziterwa na `Hypopituitarism` (kubura imisemburo):

Kubura imisemburo imwe cyangwa nyinshi bishobora gutera indwara nk'izi:

• Kunanirwa kw'intanga ngore: Kudakora neza kw'intanga ngore z'intanga ngore bitewe no kugabanuka k'umusemburo wa ACTH.
• Kubura imisemburo ikura (GHD): Kugabanuka k'urugero rw'imisemburo ya HGH. Muri make, gukura bishobora kugabanuka.
• Hypogonadism yo hagati: Kugabanuka kw'ikorwa ry'imisemburo y'ibitsina iva mu ngirabuzimafatizo z'imyororokere (intanga ngabo cyangwa udusabo tw'intanga) bitewe n'igabanuka ry'urugero rwa FSH na/cyangwa LH.
• Hypothyroidism yo hagati: Hypothyroidism iterwa no kugabanuka k'umusemburo wa TSH.

Zimwe mu ndwara ziterwa na `Hyperpituitarism` (izamuka ry'urugero rw'imisemburo):

Ubwiyongere bw'imisemburo imwe cyangwa nyinshi bushobora gutera indwara nk'izi:

• Acromegaly: Indwara idakunze kugaragara iterwa no kuba umuntu mukuru afite HGH nyinshi. Muri iyi ndwara, amagufwa n'ingingo bikura mu buryo budasanzwe.
• Gigantism: Umwana muremure cyane cyangwa umuntu mukuru ukiri muto ukagira urugero rukabije rw'imisemburo ya HGH. Ibi nabyo ni gake cyane.
• Indwara ya Cushing: Ikorwa ryinshi ry'umusemburo wa ACTH rituma imisemburo ya adrenal ikora cortisol nyinshi. Iyi ni ubwoko bw'indwara yitwa Cushing's syndrome.
• Hyperprolactinemia: Ikorwa ryinshi rya hormone ya prolactine.
• Hyperthyroidism yo hagati: Gland ya tiroyide ikora cyane bitewe no gukora cyane kwa TSH. Iyi ni impamvu idakunze kubaho cyane itera hyperthyroidism.

Reka twige bike kuri Adenomas zo mu bwonko.

Adenoma ya pituitary ni ikibyimba gikura mu gasabo ka pituitary. Ariko ntugahangayike, akenshi ibi biba ari ibibyimba bikura buhoro buhoro, bitari kanseri (bitari byiza).

Ariko, izi adenoma zishobora gukurura uturemangingo dusanzwe twa pituitary no kuzibuza gukora neza. Ibi bishobora gutera ``Hypopituitarism`` (umusaruro muke w'imisemburo), cyane cyane iyo ikibyimba ari kinini. Hari igihe, izi kanseri zishobora no gukora imisemburo myinshi, ishobora gutera ``Hyperpituitarism`` (umusaruro mwinshi w'imisemburo).

Hari ubwoko butandukanye bwa adenomas zikora (zikora) z’imbere mu gatuza k’umura (anterior pituitary anterior adenomas):

• Prolactinoma: Ikora imisemburo myinshi ya prolactine. Ubu ni bwo bwoko bukunze kugaragara bwa pituitary adenoma.
• Somatotroph adenoma: Ikora imisemburo myinshi cyane (GH).
• Corticotroph adenoma: Ikora imisemburo ya ACTH irenze urugero.
• Adenoma ya Thyrotroph: Ikora imisemburo ya TSH nyinshi cyane.
• Gonadotroph adenoma: Ikora imisemburo ya LH na FSH irenze urugero.

Ese hari ibizamini bishobora kugenzura niba agahu k'imbere k'ubwonko bwanjye gafite ubuzima bwiza?

Yego, niba ufite ibimenyetso by'ikibazo ku gasabo k'imbere k'umura, muganga wawe ashobora gutegeka ko hagenzurwa urugero rw'imisemburo. Ibi akenshi biba ari ibizamini by'amaraso .

Niba ibisubizo by'ibipimo by'amaraso yawe bigaragaza ikintu kidasanzwe, muganga wawe ashobora kukugira inama yo gupima MRI kugira ngo arebe impyiko yawe ya pituitary.

None se, ni iki twakora kugira ngo iyi gland ya pituitary y'imbere ikomeze kugira ubuzima bwiza?

Mu by'ukuri, ntabwo ushobora kwirinda buri gihe ibi bibazo by'imyakura ya pituitary. Ariko ikintu kimwe cy'ingenzi ushobora gukora ni ukwita ku mutwe wawe. Ibikomere byo mu mutwe, cyane cyane ibikomere byo mu bwonko (TBIs), bishobora kwangiza imyakura ya pituitary. Iyo bibaye, bishobora gukora imisemburo myinshi cyane cyangwa mike cyane.

Dore bimwe mu bintu ushobora gukora kugira ngo wirinde ibikomere byo mu mutwe no mu bwonko:

• Buri gihe wambara umukandara w'imodoka iyo uri mu modoka.
• Fata imodoka witonze.
• Ambara ingofero iyo utwaye igare, moto, cyangwa ukina siporo ikomeye.
• Fata ingamba zo kwirinda kugwa, cyane cyane niba uri mu kaga gakomeye ko kugwa. Ushobora gukora ibintu nko gukuraho inzitizi mu rugo rwawe, gukoresha icyuma gifasha kugenda, no kugumana amaso meza.
• Niba ufite abana bato, komeza ahantu ho gukinira hatekanye.

Ibuka: Agahu ka pituitary kawe k’imbere ni urugingo ruto, ariko rufite imbaraga, kandi rw’ingenzi rukora imisemburo itandukanye igira ingaruka ku buzima bwacu.

Amaherezo, ibintu byo kwibuka

Rero, urashobora kubona akamaro k'iyi gland ya pituitary y'imbere mu mubiri wacu. Kubera iyo mpamvu, rimwe na rimwe bishobora kugorana kumenya neza niba ibimenyetso bimwe na bimwe biterwa n'ikibazo cy'iyi gland ya pituitary cyangwa ikindi kintu.

Igikuru ni uko niba ugaragaje ibimenyetso bishya bidasanzwe, cyangwa niba uhangayikishijwe n'ikimenyetso ufite, jya kwa muganga ukaganira kuri byo.Bashobora gukora ibizamini bike byoroshye kugira ngo barebe ubuzima bwawe. Iyo hari ikibazo, gishobora kumenyekana no kuvurwa vuba.
