Yintoni iCamcitonin Exam kwaye yenziwa njani

Umxholo

• Yenzelwe ntoni
• Luqhutywa njani uviwo
• Uvavanya njani iziphumo zoviwo

I-Calcitonin yihomoni eveliswe kwidlala lengqula, umsebenzi wayo kukulawula ubungakanani becalcium ejikeleza egazini, ngokusebenzisa izinto ezinje ngokuthintela ukubuyiswa kwakhona kwecalcium emathanjeni, ukunciphisa ukufunxeka kwecalcium emathunjini kunye nokwandisa ukuphuma kwayo izintso.

Olona phawu lubalulekileyo kuvavanyo lwe-calcitonin kukufumanisa uhlobo lomhlaza wedlala lengqula obizwa ngokuba yi-medullary thyroid carcinoma, ithathwa njengesiphawuli sethumba, kuba ibangela ukuphakama okubalulekileyo kwale hormone. Uvavanyo lobukho be-thyroid C-cell hyperplasia yenye into ebonisa rhoqo, nangona le hormone inokuphakanyiswa kwezinye iimeko, ezinje ngomhlaza wemiphunga okanye webele, umzekelo.

Njengeyeza, ukusetyenziswa kwe-calcitonin kungabonakaliswa kunyango lwezifo ezinjenge-osteoporosis, i-calcium eninzi egazini, isifo sikaPaget okanye i-reflex systematic dystrophy. Ukuba ufuna ukwazi ngakumbi malunga ne-calcitonin, jonga ukuba yintoni i-calcitonin kunye nento eyenzayo.

Yenzelwe ntoni

Uvavanyo lwe-calcitonin lunoku-odolwa:

• Ukuvavanywa kobukho be-medullary thyroid carcinoma;
• Uphando lwe-hyperplasia yamaseli e-C, aziiseli ze-thyroid ezivelisa i-calcitonin;
• Uvavanyo lwezihlobo zezigulana ezine-medullary thyroid carcinoma, ekufumaniseni ithumba kwangaphambili;
• Ukuqwalaselwa kwempendulo kunyango lwe-medullary thyroid carcinoma;
• Ukulandelwa komhlaza emva kokususwa kwe-thyroid, njengoko kulindeleke ukuba ixabiso liphantsi kwimeko yokunyanga.

Nangona ezi luphawu oluphambili, kufanele kukhunjulwe ukuba i-calcitonin inokunyuswa nakwezinye iimeko, ezinje ngezinye iintlobo zomhlaza, ezinje ngeleukemia, imiphunga, ipancreatic, umhlaza webele okanye umhlaza, phambi kobukho besifo sezintso esinganyangekiyo, ngexesha usulelo lwebhaktiriya, i-hypergastrinemia, okanye njengesiphumo se-hyperparathyroidism hypercalcemia okanye ezinye iimeko.

Luqhutywa njani uviwo

Umthamo weCalcitonin wenziwa elebhu, ngokwesicelo sikagqirha, apho kuthathwa isampulu yegazi ukufumana amanqanaba asisiseko.

Ixabiso leCalcitonin liphenjelelwa ziimeko ezininzi, ezibandakanya ukusetyenziswa kwamayeza athile, anje nge-Omeprazole okanye i-corticosteroids, ubudala, ukukhulelwa, ukutshaya kunye nokusela utywala, ke indlela yokwenza uvavanyo ukuba luthembeke ngakumbi kukwenza kunye nogqirha. Uvavanyo lwe-infusion ye-calcium okanye ye-pentagastrin, ngaphandle kwezikhuthazi ezinamandla ze-calcitonin secretion.

Uvavanyo lwe-calcitonin stimulus kunye ne-calcium infusion yeyona nto ifumanekayo, kwaye yenziwa kusasa, kwisisu esingenanto. I-calcium ifakwe kwi-vein, kwi-0, 2, 5 kunye ne-10 imizuzu emva kokufakwa, ukuvavanya ukuba ipateni yokwanda ithathwa njengesiqhelo okanye hayi.

Uvavanya njani iziphumo zoviwo

Amaxabiso esiqhelo esalathiso se-calcitonin anokuhluka ngokuxhomekeke kwilabhoratri evavanya. Amaxabiso aqhelekileyo ngalawo angaphantsi kwe-8.4 pg / ml emadodeni kunye ne-5 pg / ml kwabasetyhini. Emva kovuselelo lwecalcium, ezo zingaphantsi kwe-30 pg / ml kunye ne-positive xa zingaphezulu kwe-100 pg / ml zinokujongwa njengesiqhelo. Phakathi kwe-30 kunye ne-99 pg / dl, uvavanyo luthathwa ngokungagungqi, kwaye kufuneka kwenziwe olunye uvavanyo ukuqinisekisa isifo.
