ʻO Formaldehyde a me glutaraldehydeʻo ia nā mea kemika ʻelua i hoʻohana ʻia ma ke ʻano he mau mea hoʻopili i nā noi like ʻole, ʻoi aku hoʻi ma nā kahua o ka biology, kemika, a me ka ʻepekema mea. ʻOiai lākou e lawelawe ana i nā kumu like i ka hoʻopili ʻana i nā biomolecules a me ka mālama ʻana i nā specimens biological, loaʻa iā lākou nā waiwai kemika like ʻole, ka reactivity, ka toxicity, a me nā noi.
Nā mea like:
Nā Mea Hoʻohuihui: ʻO ka formaldehyde a meʻO ka glutaraldehyde he mau aldehydes, ʻo ia hoʻi, he hui carbonyl (-CHO) ko lākou ma ka hopena o ko lākou ʻano molekala. ʻO kā lākou hana nui ka hana ʻana i nā pilina covalent ma waena o nā hui hana o nā biomolecules, e hopena ana i ka crosslinking. He mea nui ka crosslinking no ka hoʻopaʻa ʻana i ke ʻano o nā laʻana biological, e hoʻolilo iā lākou i ʻoi aku ka ikaika a me ke kūpaʻa i ka degradation.
Nā Hoʻohana Biomedical: Loaʻa ka hoʻohana nui ʻana o ka formaldehyde a me ka glutaraldehyde i ke kahua biomedical. Hoʻohana pinepine ʻia lākou no ka hoʻopaʻa ʻana i nā ʻiʻo a me ka mālama ʻana i nā haʻawina histology a me pathology. Mālama nā ʻiʻo i hoʻopili ʻia i ko lākou kūpaʻa kūkulu a hiki ke hana hou ʻia no nā kumu loiloi a me nā diagnostics like ʻole.
Ka Mana ʻana i nā Microbial: Loaʻa i nā mea ʻelua nā waiwai antimicrobial, e lilo ai lākou i mea waiwai nui i nā kaʻina hana disinfection a me sterilization. Hiki iā lākou ke hoʻopau i nā bacteria, nā virus, a me nā fungi, e hōʻemi ana i ka pilikia o ka haumia i nā wahi hoʻokolohua a me nā lako lapaʻau.
Nā Hoʻohana ʻOihana: ʻO ka formaldehyde a meglutaraldehydehoʻohana ʻia i nā noi ʻoihana like ʻole. Hoʻohana ʻia lākou i ka hana ʻana i nā mea hoʻopili, nā resins, a me nā polymers, a me nā ʻoihana ʻili a me ka lole.
Nā ʻokoʻa:
ʻAno Kemika: ʻO ka ʻokoʻa nui ma waena o ka formaldehyde a me ka glutaraldehyde aia i ko lākou mau ʻano molekala. ʻO Formaldehyde (CH2O) ka aldehyde maʻalahi loa, i haku ʻia me hoʻokahi ʻātoma kalapona, ʻelua mau ʻātoma hydrogen, a me hoʻokahi ʻātoma oxygen. ʻO Glutaraldehyde (C5H8O2), ma ka ʻaoʻao ʻē aʻe, he aliphatic aldehyde paʻakikī, i haku ʻia me ʻelima mau ʻātoma kalapona, ʻewalu mau ʻātoma hydrogen, a me ʻelua mau ʻātoma oxygen.
Ka Hana Hou: ʻOi aku ka pane ʻana o Glutaraldehyde ma mua o ka formaldehyde ma muli o kona kaulahao kalapona lōʻihi. ʻO ke alo o ʻelima mau ʻātoma kalapona i loko o ka glutaraldehyde e ʻae iā ia e hoʻopili i nā mamao lōʻihi ma waena o nā hui hana ma nā biomolecules, e alakaʻi ana i ka crosslinking wikiwiki a ʻoi aku ka maikaʻi.
Ka Pono o ke Keʻapili ʻana: Ma muli o kona reactivity kiʻekiʻe, ʻoi aku ka maikaʻi o ka glutaraldehyde i ka keʻapili ʻana i nā biomolecules nui aʻe, e like me nā protein a me nā enzymes. ʻO Formaldehyde, ʻoiai hiki ke keʻapili ʻana, pono paha i ka manawa hou aʻe a i ʻole nā ʻano kiʻekiʻe aʻe e hoʻokō ai i nā hopena hoʻohālikelike me nā molekala nui aʻe.
ʻAkika: Ua ʻike ʻia ʻo Glutaraldehyde he ʻoi aku ka ʻawahia ma mua o ka formaldehyde. ʻO ka hoʻopili lōʻihi a nui paha i ka glutaraldehyde hiki ke hoʻonāukiuki i ka ʻili a me ka hanu, a ua manaʻo ʻia he sensitizer, ʻo ia hoʻi hiki ke alakaʻi i nā hopena alerika i kekahi poʻe. I ka hoʻohālikelike ʻana, he carcinogen kaulana ka formaldehyde a he mau pilikia olakino, ʻoiai ke hanu ʻia a i ʻole e pili ana i ka ʻili.
Nā noi: ʻOiai ua hoʻohana ʻia nā kemika ʻelua i ka hoʻopaʻa ʻana i nā ʻiʻo, makemake pinepine ʻia lākou no nā kumu like ʻole. Hoʻohana pinepine ʻia ka Formaldehyde no nā noi histological maʻamau a me ka embalming, ʻoiai ʻoi aku ka kūpono o ka glutaraldehyde no ka mālama ʻana i nā ʻano cellular a me nā wahi antigenic i ka microscopy electron a me nā haʻawina immunohistochemical.
Paʻa: ʻOi aku ka leʻaleʻa o ka Formaldehyde a ʻoi aku ka wikiwiki o ka mahu ʻana ma mua o ka glutaraldehyde. Hiki i kēia waiwai ke hoʻololi i nā koi lawelawe a me ka mālama ʻana o nā mea hoʻopili.
I ka hōʻuluʻulu manaʻo, he mau ʻano like ko formaldehyde a me glutaraldehyde ma ke ʻano he mau mea hoʻopili, akā ʻokoʻa nui lākou i ko lākou mau ʻano kemika, ka reactivity, ka toxicity, a me nā noi. He mea nui ka hoʻomaopopo pono ʻana i kēia mau ʻokoʻa no ke koho ʻana i ka mea hoʻopili kūpono no nā kumu kikoʻī a me ka hōʻoia ʻana i ka hoʻohana palekana a me ka pono i nā ʻano ʻepekema, lāʻau lapaʻau, a me nā ʻoihana like ʻole.
