| EC | 233-271-0 |
| UN | 1660 |
Yintoni le nto ?
I-nitric oxide yigesi engenambala, engenavumba kubushushu begumbi. Yimolekyuli esebenzayo kakhulu kwaye ihlala ixesha elifutshane ngenxa yokuthambekela kwayo ukusabela ngokukhawuleza kunye nezinye izinto. HAYI yimolekyuli ebonisa umqondiso emzimbeni womntu kwaye idlala indima ebalulekileyo kwiinkqubo ezahlukeneyo zomzimba. Isebenza njenge-vasodilator, inceda ukuphumla kunye nokwandisa imithwalo yegazi, elawula ukuhamba kwegazi kunye noxinzelelo lwegazi. Nangona i-NO ngokwayo ayinayo ityhefu kwiindawo eziphantsi, inokuba negalelo ekwenzeni i-nitrogen oxides eyingozi (NOx) xa isabela nge-oksijini kunye nezinye i-nitrogen compounds emoyeni. Ezi zixhobo ze-NOx zinokuba nemiphumo emibi yendalo kunye nempilo.
Kusetyenziswa phi le mathiriyeli ?
I-nitric oxide (NO) inezicelo ezininzi ezibalulekileyo kwiinkalo ezahlukeneyo, kuquka amayeza, ishishini, kunye nophando. Nalu usetyenziso oluqhelekileyo lwenitric oxide:
1. Amayeza:
- - I-Vasodilator: HAYI isetyenziswe kwizicwangciso zonyango njenge-vasodilator yokuphumla kunye nokwandisa imithwalo yegazi. Le propati isetyenziswa kunyango lweemeko ezifana noxinzelelo lwegazi lomphunga kunye nezifo ezithile zentliziyo.
- - I-Nitric Oxide e-Inhaled (iNO): I-nitric oxide e-inhaled isetyenziselwa kwiiyunithi zokunakekelwa kwe-neonatal intensive care units (NICUs) ukunyanga iintsana ezisanda kuzalwa ezine-persistent pulmonary hypertension.
- - I-Erectile Dysfunction: HAYI idlala indima ekuphumleni kwemithambo yegazi kwi-penis, kunye neyeza ezifana ne-sildenafil (eyaziwa ngokuba yi-Viagra) isebenza ngokunyusa imiphumo ye-NO yokuphatha ukungasebenzi kwe-erectile.
2. Uphando lwebhayoloji:
- -Umqondiso weSeli: HAYI isebenza njengemolekyuli yomqondiso kwiinkqubo ezahlukeneyo zomzimba, iyenza ibe sisixhobo esibalulekileyo kuphando lwebhayoloji yeselula kunye nemolekyuli.
- - I-Neurotransmission: HAYI ibandakanyeka kwi-neuronal signaling kunye ne-neurotransmission, kwaye isifundo sayo sibalulekile kuphando lwe-neuroscience.
3. Ishishini:
- - Ukuveliswa kwe-Nitric Acid: HAYI i-precursor kwimveliso ye-nitric acid (HNO3), esetyenziselwa ukuveliswa kwezichumisi kunye neekhemikhali ezahlukeneyo.
- - Ishishini lokutya: Ingasetyenziswa njenge-antimicrobial agent kwishishini lokutya ukulawula ukukhula kweebhaktheriya kwiimveliso ezithile.
4. Uhlalutyo lweKhemistri:HAYI ingasetyenziswa kwiindlela zokuhlalutya zekhemistri, ezifana ne-chemiluminescence, ukufumanisa kunye nokulinganisa i-compounds eyahlukeneyo kunye nokulandelela iigesi.
5. UPhando lokusiNgqongileyo:HAYI idlala indima kwimichiza ye-atmospheric kunye nomgangatho womoya. Uphononongo lwayo lubalulekile ekuqondeni ukusabela kwe-atmospheric kunye nokwakheka kwezinto ezingcolisa i-nitrogen dioxide (NO2).
6. Ukucocwa kwamanzi amdaka:AKUKHO inokusetyenziswa kwiinkqubo zokucocwa kwamanzi amdaka ukususa ukungcola kunye nokunyanga amanzi ngokufanelekileyo.
7. Inzululwazi yezinto eziphathekayo:AKUKHO unokuqeshwa kuphando lwesayensi yezixhobo kunyango lomphezulu kunye nokuguqulwa kwezinto.
Qaphela ukuba izicelo ezithile kunye nemimiselo yokusetyenziswa kwesi sixhobo/imveliso inokwahluka ngokwelizwe, ishishini kunye nenjongo. Njalo ulandele izikhokelo zokhuseleko kwaye udibane neengcali ngaphambi kokusebenzisa le nto / imveliso kuyo nayiphi na isicelo.
