Yɛn nipadua te sɛ afiri a ɛyɛ nwonwa yiye na ɛyɛ den, ɛnte saa? Yɛn nyinaa nim sɛ biribiara a ɛwɔ afiri yi mu no, yɛn amemene na ɛhwɛ so. Nanso so wunim sɛ w’amemene mu no, ntini ketewaa bi te sɛ dompe ketewaa bi wɔ hɔ, a ɛma nkwaadɔm a ɛho hia paa a ɛhwɛ nsu dodow a ɛwɔ wo nipadua mu so, ɛma awotwaa no twetwe bere a worewo, na ɛma ɛna ne abofra ntam abusuabɔ a ɛyɛ nwonwa no ba? Ɛno na yɛrebɛka ho asɛm nnɛ. Yɛfrɛ eyi Pituitary Gland. Ɛnnɛ, yɛbɛka ne fã titiriw bi a ɛne Posterior Pituitary ho asɛm kɔ akyiri.

Nea edi kan no, ma yɛnhwɛ, dɛn ne pituitary gland?

Fa no sɛ wo nipadua yɛ adwumakuw kɛse. Afei saa adwumakuw no panyin ne amemene no fã a wɔfrɛ no hypothalamus. Wɔ saa CEO yi ase no, ɔpanyin panyin bi wɔ hɔ. Ɛno ne pituitary gland no. Saa ɔhwɛfo yi ho hia yiye, efisɛ ɔhwɛ ntini afoforo pii a ɛwɔ nipadua no mu no adwuma so.

Saa pituitary gland yi wɔ w’amemene ase, wo hwene akyi, wɔ baabi a ahobammɔ wɔ paa. Wɔakyekyɛ mu abien. Te sɛ anim agyede pon a ɛwɔ ɔfese bi ne akyi adwumayɛbea.

1. Anterior Pituitary: Eyi ne ɔfã a ɛsõ sen biara na adagyew nnim sen biara. Ɛma hormone pii a ɛfa nipadua nyin, thyroid dwumadi, ne nna mu dwumadi ho na ɛma ɛba.

2. Posterior Pituitary: Oyi ne yɛn asɛmti no mu ɔkannifo. Ɛyɛ ketewaa sen anim pituitary no. Ɛnnyɛ hormone, na mmom ɛkora hormone soronko abien a hypothalamus yɛ na ɛde mena no so, na ɛma ɛkɔ mogya no mu bere a ɛho hia no.

Wɔfrɛ nhyehyɛe a ɛka ntini a ɛma nkwaadɔm nyinaa, a pituitary gland ka ho, endocrine system . Eyi ne nkitahodi nhyehyɛe a ɛsesa nnuru nkrasɛm wɔ nipadua no mu.

Enti dɛn ne saa nkwaadɔm titiriw abien a Posterior Pituitary no gyae no?

Sɛnea yɛadi kan aka no, Posterior Pituitary no te sɛ adekoradan. "Nneɛma" abien a ɛsom bo yiye na wɔde asie ha. Wɔyɛ hormone abien. Hypothalamus na ɛyɛ eyinom abien no nyinaa. Sɛ nkrasɛm bi fi hɔ fa ntini ahorow so ba a, Posterior Pituitary no gyae saa nkwaadɔm yi kɔ mogya no mu.

Nkyerɛkyerɛmu tiawa bi a ɛfa saa hormone abien yi ne sɛnea ɛyɛ adwuma ho ni.

Fa no sɛ bere bi a wo ho fifiri retu wo kɛse na sukɔm de wo. Saa bere no, wo mogya mu yɛ den kakra. Hypothalamus a ɛwɔ amemene no mu no hu eyi na ɛde sɛnkyerɛnne bi kɔ Posterior Pituitary no so, na ɛka sɛ, "Okay, afei fa ADH bi hyɛ mogya no mu." Afei ADH kɔ na ɔka kyerɛ asaabo no sɛ, "Fa nsu kakraa bi di dwuma, nnyɛ nsu pii." Ɛno na nsu dodow a wode fa mu no so tew, na ne kɔla yɛ tuntum. Sɛ nsu pii wɔ wo mu a, nea ɛne no bɔ abira na ɛba. ADH dodow so tew, na nsu a ɛboro so no fi mu sɛ nsu. So ɛnyɛ tumi a ɛyɛ nwonwa a wɔde di dwuma?

Dɛn ne nyarewa a ebetumi ne Posterior Pituitary no abata ho?

Mpɛn pii no, nyarewa atitiriw a ɛfa saa ntini yi ho no ho yɛ na. Nanso ɛtɔ mmere bi a, ɔhaw ahorow bi betumi asɔre esiane ADH ne oxytocin hormone ahorow yi a ɛtwetwe dodo (hypersecretion) anaasɛ ɛnnɔɔso (hyposecretion) nti.

1. ADH a wɔde fi nipadua mu a ɛnyɛ den

Sɛ ADH hormone a nipadua no yɛ anaasɛ eyi fi mu no so tew a, asaabo no hwere sɛnkyerɛnne a ɛbɛma asan akɔ nsu a wohia no. Eyi kyerɛ sɛ ɛkame ayɛ sɛ nsu a wonom nyinaa kowie wo nsu mu. Wɔfrɛ saa tebea yi Central Diabetes Insipidus (CDI) .

Saa tebea yi betumi afi hypothalamus anaa pituitary gland a ɛsɛe no mu aba. Ɛtɔ da bi a, wontumi nhu nea ɛde ba biara.

Nsɛnkyerɛnne atitiriw:

• Nsu a wɔtow boro so (Polyuria): Wubetumi de nsu lita pii akɔ da biara. Ebia ɛsɛ sɛ wotaa kɔ baabi a woguare.
• Sukɔm a ɛboro so (Polydipsia): Ɛmfa ho nsu dodow a wobɛnom no, wote nka sɛ worennya nea ɛdɔɔso. Bere a wo nipadua rehwere nsu no, w’amemene no kyerɛ wo sɛ kɔ so nom nsu.
• Nsu a ɛho ntew: Sɛ woannom nsu a ɛdɔɔso a, wubetumi ahwere nsu wɔ wo nipadua mu.
• Ɔbrɛ: Sɛ ɛsɛ sɛ wotaa sɔre anadwo kɔtow wo ho a, ebetumi asɛe wo nna na ama woate nka sɛ woabrɛ da mũ no nyinaa.

2. Sɛ ADH hormone no kɔ soro a (Hypersecretion of ADH) .

Eyi ne nea edi kan no bɔ abira. Sɛ ADH hormone pii wɔ nipadua no mu a, asaabo no san twe nsu pii kɔ nipadua no mu. Eyi ma nsu pii fi nipadua no mu. Eyi ma nsu boaboa ano wɔ nipadua no mu na sodium (nkyene) dodow a ɛwɔ mogya no mu no so tew ma ɛyɛ hu. Wɔfrɛ saa tebea yi SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion) .

Nneɛma a ebetumi de eyi aba:

• Nnuru bi (e.g., nnuru bi a wɔde sa asikreyare ne akisikuru).
• Bere a wɔyɛɛ oprehyɛn ahorow wɔ aduru a wɔde kum nipadua no mu akyi.
• Tebea horow te sɛ amemene mu opira, ɔyare mmoawa, anaa ɔyare a ɛma obi hwe ase.

Nsɛnkyerɛnne atitiriw (eyinom taa fi sodium a ɛba fam wɔ mogya mu):

• Akisikuru ne ɔfe.
• Tipaeɛ.
• Te a wobɛte nka sɛ worehwere wo kari pɛ na worebɛhwe ase.
• Adwene mu nsakrae te sɛ nkae a ɛyera ne basabasayɛ.

3. Ɔhaw ahorow a ɛfa hormone Oxytocin ho

Nokwarem no, nyarewa a ɛnam saa hormone yi, oxytocin, a ɛba fam anaa ɛkɔ soro so de ba no ho yɛ na koraa. Ɛyɛ tebea a ɛntaa nsi koraa.

• Sɛ oxytocin sua a: Ebia awotwaa no rentwitwa yiye bere a wɔrewo no, na ebia nufusu renkɔ mu bere a wɔawo akokoaa no akyi.
• Sɛ oxytocin kɔ soro a: Eyi nso ho yɛ na koraa. Ebetumi ama awotwaa no ntini anyin dodo, na ama ayɛ den ama akokoaa no sɛ obekura mu.

Wobɛyɛ dɛn ahu sɛ ɔhaw bi wɔ Posterior Pituitary no ho?

Sɛ wowɔ sɛnkyerɛnne ahorow a yɛadi kan aka ho asɛm no a, wo duruyɛfo no bedi kan abisa wo wo sɛnkyerɛnne ahorow no ho asɛm. Afei, ebia wɔbɛyɛ nhwehwɛmu ahorow bi de ahu wo hormone dodow ho mfonini a edi mu.

• Mogya mu Nhwehwɛmu: Wobetumi asusuw nneɛma te sɛ ADH hormone dodow ne mogya mu sodium dodow.
• Nsuo mu Nhwehwɛmu: Wubetumi ahu sɛnea wo nsu no mu yɛ duru anaasɛ ɛyɛ teateaa.
• MRI scan: Eyi boa ma wohu sɛ ebia akisikuru anaasɛ pituitary gland anaa hypothalamus no asɛe anaa.

Wo duruyɛfo no begyina nea ebefi nhwehwɛmu ahorow yi mu aba so asi ayaresa ho gyinae.

Bere bɛn na ɛsɛ sɛ mekɔ oduruyɛfo nkyɛn?

Tebea horow a yɛaka ho asɛm no pii ho yɛ na koraa. Nanso, sɛ wuhu nsakrae bi wɔ wo nipadua mu a, ɛbɛyɛ papa sɛ worenbu w’ani ngu so.

Titiriw no, sɛ wowɔ sɛnkyerɛnne ahorow a edidi so yi mu biako anaa nea ɛboro saa a, nsɛe bere nkɔ wo duruyɛfo nkyɛn.

• Sɛ sukɔm de wo a wuntumi nsusuw ho na wotaa tow wo ho boro so a .
• Sɛ wo ho yɛ wo yaw, wofe, wo ti yɛ wo yaw, na wote nka sɛ woankari pɛ a ntease biara nnim a.
• Sɛ mpofirim ara wote nka sɛ wo nkae ayɛ basaa na wuntumi mfa w'adwene nsi biribi so a .

Wɔ mmere a ɛte sɛ eyinom mu no, sɛ wokɔ oduruyɛfo nkyɛn na woyɛ nhwehwɛmu kakraa bi a ɛnyɛ den a, ebetumi aboa wo ma woahu sɛ ɔhaw bi wɔ hɔ anaasɛ ɛnte saa. Enti nsuro sɛ wobɛhwehwɛ aduruyɛ mu afotu.
