kungani i-nitric oxide ikulungele?
1. Yiziphi izinzuzo ze-nitric oxide?
I-nitric oxideinganweba imithambo yegazi, yandise ukugeleza kwegazi, yehlise umfutho wegazi, ithuthukise ukujikeleza kwegazi, futhi ibe nemiphumela eqeda ukuvuvukala, i-anti-oxidant, kanye nenkumbulo.
1. Dilate imithambo yegazi: I-Nitric oxide ingakhiqizwa ngokuvula amangqamuzana e-vascular endothelial, ngaleyo ndlela kunwetshwe imithambo yegazi, kuthuthukiswe ukugeleza kwegazi nokunikezwa komoyampilo wegazi.
2. Umfutho wegazi ophansi: I-Nitric oxide ingaphumuza imisipha ebushelelezi futhi inciphise i-vasoconstriction, ngaleyo ndlela yehlise umfutho wegazi.
3. Thuthukisa ukujikeleza kwegazi: I-nitric oxide ingakhuthaza ukujikeleza kwegazi, yandise ukulethwa komoyampilo nezakhi, kuyilapho inciphisa ukuqoqwa kwe-carbon dioxide kanye nemfucuza ye-metabolic.
4. Umphumela wokulwa nokuvuvukala: I-Nitric oxide ingavimbela impendulo yokuvuvukala futhi inciphise izimpawu zokuvuvukala.
5. Umphumela we-Antioxidant: I-Nitric oxide ingasusa ama-radicals mahhala futhi inciphise ukulimala kwe-oxidative.
6. Thuthukisa inkumbulo: I-Nitric oxide ingakhuthaza ukukhula nokuxhumana kwama-neurons, ngaleyo ndlela ithuthukise inkumbulo nekhono lokufunda.
2. Yikuphi ukudla okunothe nge-nitric oxide?
Okusanhlamvu nemikhiqizo yawo, amazambane nemikhiqizo yawo, ubhontshisi omisiwe nemikhiqizo yawo, imifino nemikhiqizo yawo, isikhunta nolwelwe, izithelo nemikhiqizo yazo, amantongomane nembewu, inyama yemfuyo nemikhiqizo yazo, amaqanda nemikhiqizo yazo, inhlanzi, izimfanzi, inkalankala. kanye nezimbaza, izingulube Amathenda, izintende zamakamela, izinhlanzi ze-clove (omisiwe), izibopho zezinhlanzi ezomisiwe, ama-shrimps omisiwe (izimfanzi, ama-shrimp), ama-razor clams, ama-scallops (omisiwe), i-cuttlefish (omisiwe), i-tofu ethosiwe, i-sesame paste, njll.
3. Yibuphi ububi be-nitric oxide?
I-nitric oxideindima eyinhloko emzimbeni iwukuba uvule imithambo yegazi, okungase kuholele ekuqhumeni kanye nomfutho wegazi ophansi.
I-nitric oxide, njengomphumela oseceleni we-in vitro gas, iyacasula kakhulu ulwelwesi lwamafinyila lomgudu wokuphefumula namehlo. I-nitric oxide inendawo eqinile yokwenza i-oxidizing, futhi kulula kakhulu ukuyishisa futhi iqhume ngemva kokuxhumana nezinye izinto ezivuthayo.
I-nitric oxide ifakwa kalula i-nitrogen dioxide emoyeni, enobuthi obudlulele futhi egqwalisayo. Ngemva kokuxhumana isikhathi eside nomzimba womuntu, ukunqwabelana emzimbeni kuzodala i-edema yamaphaphu, i-syndrome yokucindezeleka kokuphefumula kwabantu abadala, njll. Ukuqina kwesifuba, ukucindezeleka kokuphefumula, ukukhwehlela, isikhwehlela esinegwebu, i-cyanosis, njll. Ukugxila okuphezulu kungaholela futhi ku-methemoglobinemia. Ngakho-ke, i-nitric oxide ayiyona nje ingozi emvelweni, kodwa futhi inobuthi obungapheli emzimbeni womuntu.
4. I-nitric oxide iyithinta kanjani impilo yomuntu?
Ukulimala kwei-nitric oxideemzimbeni womuntu ngokuyinhloko ukulimaza umgudu wokuphefumula. I-nitric oxide ayizinzile futhi iguqulwa kalula ibe yi-nitrogen dioxide emoyeni ukuze ikhiqize umphumela ovuselelayo. Ama-nitrogen oxide alimaza kakhulu umgudu wokuphefumula womuntu. Ezigabeni zokuqala zokuhogela, kungase kube nezimpawu ezincane kuphela zeso nokucasuka kokuphefumula njengokungakhululeki komphimbo, ukukhwehlela okomile nokungakhululeki kokuvuka. I-edema yamaphaphu ibambezelekile kwenzeka ngemva kwesikhathi sokushiswa kwesifo amahora amaningana, amahora ayishumi noma ngaphezulu, kanye nesifo sokuphefumula esibuhlungu, okungukuthi, ukuqina kwesifuba, ukufutheka, ukuphefumula, ukukhwehlela, i-cyanosis yezindebe, i-pneumothorax ne-pneumomediastinum. I-bronchiolitis ebambezelekayo ingase ikhule ngemva kokuxazululwa kwe-edema yamaphaphu, futhi ukugxila okuphezulu kwe-nitric oxide nakho kungase kubangele i-methaemoglobinemia. I-nitric oxide iyingozi emzimbeni womuntu futhi iyigesi enobuthi emzimbeni womuntu. Ubuthi obungamahlalakhona be-nitric oxide bungaphinda bubonakale njenge-neurasthenia kanye nokuvuvukala okungapheli komzila womoya, ngesiguli ngasinye esiba ne-pulmonary fibrosis. Ngakho-ke, ekukhiqizeni nasekuphileni, zama ukugwema ukuthintana ne-nitric oxide nama-nitrogen oxides.
