Myoglobin: he aha ia, hana a he aha ke ʻano ke kiʻekiʻe ia
Anter
Hana ʻia ka hoʻokolohua myoglobin e nānā i ka nui o kēia protein i loko o ke koko i mea e ʻike ai i nā ʻeha o ka mākala a me ka naʻau. Aia kēia protein i loko o ka puʻuwai puʻuwai a me nā mākala ʻē aʻe i ke kino, e hāʻawi ana i ka oxygen e pono ai no ka hoʻoneʻe ʻana o nā mākala.
No laila, ʻaʻohe maʻa mau ka myoglobin i ke koko, hoʻokuʻu wale ia ke loaʻa kahi ʻeha i kahi mākala ma hope o kahi ʻeha haʻuki, no ka laʻana, a i ʻole i ka puʻuwai puʻuwai, kahi e hoʻomaka ai nā pae o kēia protein e hoʻonui i ke koko 1 a 3 mau hola ma hope o ka infarction, piko ma waena o 6 a me 7 mau hola a hoʻi i ka maʻamau ma hope o 24 mau hola.
No laila, i ka poʻe olakino, maikaʻi ʻole ka hoʻāʻo myoglobin, maikaʻi wale nō ke loaʻa ka pilikia me nā mākala i ke kino.
Nā hana Myoglobin
Aia ʻo Myoglobin i nā mākala a he kuleana no ka hoʻopaʻa ʻana i ka oxygen a mālama a hiki i ka wā e pono ai. No laila, i ka wā o ka hoʻoikaika kino, no ka laʻana, hoʻokuʻu ʻia ka oxygen i mālama ʻia e myoglobin e hana i ka ikehu. Eia nō naʻe, i ke alo o nā kūlana e hōʻino ana i nā mākala, hiki ke hoʻokuʻu ʻia ka myoglobin a me nā protein ʻē aʻe i loko o ka holo.
Aia ʻo Myoglobin i loko o nā mākala āpau o ke kino, e pili ana i ka mākala puʻuwai, a no laila hoʻohana pū ʻia ma ke ʻano he māka o ka ʻeha puʻuwai. No laila, noi ʻia ke ana o myoglobin i ke koko ke loaʻa ke kanalua no kahi ʻeha i hōʻeha ʻia e:
- Hoʻoiho muscular;
- Pā ikaika i nā mākala;
- Hoʻomaʻā ka mākala;
- Rhabdomyolysis;
- Huikau;
- Maʻi hohola.
ʻOiai hiki ke hoʻohana ʻia ke kuhi ʻia ka puʻuwai puʻuwai, ʻo ka hoʻāʻo i kēia manawa e hōʻoiaʻiʻo ʻia ai ka hōʻoia ʻo ia ka hōʻike troponin, kahi e ana ai i ka loaʻa ʻana o kahi protein ʻē aʻe i loaʻa wale i ka puʻuwai a ʻaʻole i hoʻohuli ʻia e nā ʻeha ʻē aʻe. E aʻo hou e pili ana i ka hoʻokolohua troponin.
Eia hou, inā e hoʻokūpaʻa ʻia ke alo o myoglobin i ke koko a i loko o nā waiwai kiʻekiʻe loa, hiki ke hana ʻia kahi hōʻike mimi e loiloi i ke olakino olakino, ʻoiai nā pae kiʻekiʻe loa o myoglobin hiki ke hōʻeha i nā puʻupaʻa, e hōʻino ana i kāna hana.
Pehea e pau ai ka hōʻike
ʻO ke ala nui e hana ai i ka hoʻāʻo myoglobin ma o ka hōʻiliʻili ʻana i kahi hāpana koko, akā naʻe, i nā manawa he nui, noi paha ke kauka no kahi mimi, no ka mea ua kānana ʻia a hoʻopau ʻia ka myoglobin e nā puʻupaʻa.
No kekahi o nā hōʻike, ʻaʻole pono e hana i kekahi ʻano hoʻomākaukau, e like me ka hoʻokē ʻai.
He aha ka manaʻo o myoglobin kiʻekiʻe
ʻO ka hopena maʻamau o ka hoʻokolohua myoglobin he maikaʻi ʻole a i ʻole ma lalo o 0.15 mcg / dL, ʻoiai ma nā kūlana maʻamau ʻaʻole loaʻa ka myoglobin i ke koko, i nā mākala wale nō.
Eia nō naʻe, ke hōʻoia ʻia nā waiwai ma luna o 0.15 mcg / dL, hōʻike ʻia ma ka hoʻāʻo he kiʻekiʻe ka myoglobin, kahi e hōʻike pinepine nei i kahi pilikia i ka puʻuwai a i ʻole nā mākala ʻē aʻe i ke kino, a no laila e kauoha paha ke kauka i nā hoʻokolohua hou aku. . e like me nā electrocardiogram a i ʻole nā mea hōʻailona puʻuwai e hōʻea i kahi ʻike kikoʻī.
Hiki i nā pae kiʻekiʻe o ka myoglobin ke hōʻailona o nā pilikia ʻē aʻe i pili ʻole i nā mākala, e like me ka inu ʻana i ka waiʻona a i ʻole nā pilikia o nā puʻupaʻa, no laila e loiloi mau ʻia ka hopena me ke kauka e pili ana i ka mōʻaukala o kēlā me kēia kanaka.
