Vasoactive uvavanyo lwepeptide yamathumbu

I-Vasoactive intestinal peptide (VIP) luvavanyo olulinganisa inani le-VIP egazini.

Isampulu yegazi iyafuneka.

Akufuneki utye okanye usele nantoni na iiyure ezine ngaphambi kovavanyo.

Xa kufakwa inaliti ukutsala igazi, abanye abantu baziva iintlungu eziphakathi. Abanye baziva behlaba okanye behlaba kuphela. Emva koko, kunokubakho ukubetha okanye ukukrala kancinci. Oku kuya kuhamba kungekudala.

Olu vavanyo lusetyenziselwa ukulinganisa inqanaba le-VIP egazini. Inqanaba eliphezulu kakhulu lidla ngokubangelwa yi-VIPoma. Esi sisifo esinqabileyo kakhulu esikhupha i-VIP.

I-VIP yinto efumaneka kwiiseli kuwo wonke umzimba. Amanqanaba aphezulu aqhele ukufunyanwa kwiiseli kwinkqubo yeemvakalelo kunye nasemathunjini. I-VIP inemisebenzi emininzi, kubandakanya ukukhululeka kwezihlunu ezithile, ukubangela ukukhutshwa kwehomoni kwiipancreas, isisu, kunye ne-hypothalamus, kunye nokonyusa inani lamanzi kunye neelectrolyte ezifihliweyo kwipancreas nakwisisu.

IiVIPomas zivelisa kwaye zikhulule i-VIP egazini. Olu vavanyo lwegazi lujonga inani le-VIP egazini ukubona ukuba umntu unayo na i-VIPoma.

Olunye uvavanyo lwegazi kubandakanya i-serum potassium inokwenziwa ngaxeshanye novavanyo lwe-VIP.

Amaxabiso aqhelekileyo kufuneka abe ngaphantsi kwe-70 pg / mL (20.7 pmol / L).

Abantu abane-VIP-secreting tumors bahlala benamaxabiso ama-3 ukuya kuma-10 amaxesha ngaphezulu kwoluhlu oluqhelekileyo.

Amaxabiso esiqhelo ahluka kancinci phakathi kweelebhu ezahlukeneyo. Ezinye iilebhu zisebenzisa imilinganiselo eyahlukeneyo okanye ukuvavanya iisampulu ezahlukeneyo. Thetha nogqirha wakho malunga nentsingiselo yeziphumo zakho zovavanyo.

Inqanaba eliphezulu kuneliqhelekileyo, kunye neempawu zorhudo olunamanzi kunye nokugungxula, kunokuba luphawu lweVIPoma.

Akukho mngcipheko ubandakanyekileyo ekuthatheni igazi lakho. Imithambo kunye nemithambo iyahluka ngobukhulu ukusuka kwisigulana esinye ukuya kwelinye nakwelinye icala lomzimba liye kwelinye. Ukuthatha igazi kwabanye abantu kunokuba nzima ngakumbi kunabanye.

Eminye imingcipheko enxulumene nokutsalwa kwegazi incinci kodwa inokubandakanya:

• Ukopha kakhulu
• Ukufa isiqaqa okanye ukuziva ungenantloko
• Ukugqobhoza okuninzi ukufumana imithambo
• I-Hematoma (igazi eliqokelela phantsi kwesikhumba)
• Usulelo (umngcipheko omncinci nangaliphi na ixesha ulusu lwaphukile)
