ʻO ka N-Acetyl-L-cysteine kahi waikawa amino acetylated me nā waiwai antioxidant a me nā mucolytic.Ua hōʻike kēia mau hana ʻelua i ka N-Acetyl-L-cysteine e pili pono ana i ka mālama kemika o ka cystic fibrosis, kahi e hoʻomaikaʻi ai ke ʻano antioxidant / hōʻemi o ka pūhui i ke ʻano o ka systemic redox imbalance state o CF a me nā waiwai mucolytic o ka pūhui i keakea i ka. ʻO ka congestion a me ka mumū e pili ana i kēia kūlana redox.Ma ke ʻano he mucolytic, lawelawe ʻo N-Acetyl-L-cysteine e hoʻopau i nā paʻa disulfide ma waena o nā mucoproteins, wehe a hoʻomaʻemaʻe i ka viscosity o ka sputum.Hōʻike ka N-Acetyl-L-cysteine i ka hana hoʻomaikaʻi i ka glutathione, e hōʻike ana i ka hana antioxidant ma o kā lākou hana thiol, a ua hōʻike ʻia ʻelua e pale aku i ke koʻikoʻi peroxidative e pili ana i ka haʻalulu septic.Ua hōʻike pū ʻia ʻo N-Acetyl-L-cysteine e hoʻoulu i ka apoptosis i loko o nā ʻiʻo ʻiʻo maʻemaʻe vascular, e hōʻike ana he pane ʻokoʻa kēia mau cell i nā loli i ke kūlana hoʻemi-oxidation ma mua o nā ʻiʻo ʻē aʻe i pale ʻia e ke alo o nā antioxidants.Hōʻike kēia hoʻopili kupanaha i nā ʻiʻo ʻiʻo maʻemaʻe vascular i ka N-Acetyl-L-cysteine ma ke ʻano he mea hoʻohiki i ka ulu ʻana o arteriosclerotic o kēia mau cell.
Nā waiwai kemika: N-acetyl-L-cysteine keʻokeʻo crystalline pauka, me ka ʻala e like me ke kāleka a me ka ʻono ʻawaʻawa.Hygroscopic, hoʻoheheʻe ʻia i ka wai a i ʻole ethanol, hiki ʻole ke hoʻoheheʻe ʻia i ka etera a me ka chloroform.He ʻakika ia i ka wai wai (pH2-2.75 i 10g/LH2O), mp101-107 ℃ Chemicalbook.ʻO kēia huahana he N-acetylated derivative o ka cysteine.Aia i loko o ka mole he pūʻulu sulfhydryl, hiki iā ia ke uhaki i ka paʻa disulfide (-SS-) o ka mucin peptide bond, a laila e hoʻohuli i ke kaulahao mucin i kahi kaulahao peptide molekula liʻiliʻi, e hōʻemi ana i ka No ka viscosity o ka mucin, he mea hoʻoheheʻe kēia huahana. ka lāʻau no ka sputum viscous, purulent sputum a me ka hanu hanu.
lāʻau pilina:
1. ʻAʻole e hoʻohana pū ʻia me ka penicillin, cephalosporin a me tetracycline antibiotics, no ka mea hiki ʻole ke hopena.
2. ʻO ka hui pū ʻana a i ʻole ka hoʻohana ʻana me isoproterenol hiki ke hoʻomaikaʻi i ka hopena curative a hōʻemi i nā hopena ʻino.
3. Hōʻalo i ka pili ʻana me nā mea metala a me nā mea hao, nā mea oxidants, a me ka oxygen.
Hoʻohana: nā mea olaola, nā mea maka, thiol (-SH) i loko o ka mole hiki ke wāwahi i ke kaulahao disulfide (-SS) e hoʻopili ana i ke kaulahao mucin peptide i loko o ka mucous phlegm.Hoʻololi ʻo Mucin i Chemicalbook i kahi kaulahao peptide molekula liʻiliʻi, e hoʻemi ana i ka viscosity o ka sputum;hiki iā ia ke uhaki i nā kaula DNA i loko o ka purulent sputum, no laila ʻaʻole hiki iā ia ke hoʻopau wale i ka sputum keʻokeʻo keʻokeʻo akā pū kekahi purulent sputum.
Hoʻohana: I ka lāʻau lapaʻau, hoʻohana ʻia ia ma ke ʻano he lāʻau hoʻoheheʻe phlegm.No ka noiʻi biochemical, hoʻohana ʻia ia ma ke ʻano he antidote no ka hoʻoheheʻe ʻana o ka phlegm a me ka make ʻana o ka acetaminophen i ka lāʻau lapaʻau.
Hoʻohana: No ka noiʻi biochemical, i ka lāʻau lapaʻau, hoʻohana ʻia ia ma ke ʻano he lāʻau hoʻoheheʻe phlegm a he antidote no ka ʻona acetaminophen.
Hoʻohana: Biochemical reagents, lāʻau lapaʻau, hoʻohana ʻia kēia huahana ma ke ʻano he expectorant, i ʻōlelo ʻia he maʻalahi e hoʻomaʻemaʻe i ka phlegm a maʻalahi hoʻi i ka ʻu.He hopena decomposition ma ka sputum viscous.ʻO ke ʻano o ka hana ʻo ia ka hui sulfhydryl i loko o ka molecular structure o kēia huahana hiki ke wāwahi i ka disulfide bond Chemicalbook i ka mucin polypeptide chain i ka mucous sputum, decompose i ka mucin, hoʻemi i ka viscosity o ka sputum, a hoʻoheheʻe a maʻalahi. ʻāʻī.He kūpono ia no nā maʻi ʻeha a me ka maʻi hanu me ka sputum mānoanoa a paʻakikī hoʻi e expectorate, a me nā hōʻailona koʻikoʻi o ka paʻakikī i ka hoʻomoʻa ʻana ma muli o ke keakea ʻana o ka nui o ka phlegm sticky.
Hoʻohana: Hiki ke hoʻohana ʻia ka N-acetyl-L-cysteine ma ke ʻano he lāʻau hoʻoheheʻe phlegm.He kūpono ia no ka hoʻopaʻa ʻana i ka hanu ma muli o ka nui o ka paʻa ʻana o ka phlegm obstruction.Eia kekahi, hiki ke hoʻohana ʻia no ka detoxification o ka ʻona acetaminophen.No ka mea he ʻala kūikawā kēia huahana, ʻo ka lawe ʻana iā ia hiki ke hoʻoulu i ka nausea a me ka luaʻi.He hopena hoʻoulu ia ma ka ʻōpū hanu a hiki ke hoʻoulu i ka bronchospasm.Hoʻohana pū ʻia me nā bronchodilators e like me isoproterenol a me kahi mea hoʻoheheʻe sputum e kipaku aku i ka sputum.ʻAʻole pono e hoʻopili ʻia me nā metala (e like me Fe, Cu), rubber, oxidants, a me nā mea ʻē aʻe.E hoʻohana me ka akahele i nā mea maʻi me ka hānō bronchial.
