I kēia mau lā, ke hoʻomohala mau nei nā ʻoihana he nui e like me ka ʻepekema mea a me ka biomedicine, ʻo chitosan, ma ke ʻano he biomaterial kūlohelohe kū hoʻokahi, ke hōʻike nei i nā manaʻolana noi ākea loa me kona mau waiwai maikaʻi loa a me nā hana like ʻole. ʻO Chitosan, kahi mea polysaccharide i unuhi ʻia mai nā pūpū o nā crustaceans e like me nā ʻōpae a me nā pāpaʻi, he ʻano kemika a me nā waiwai kino kū hoʻokahi, no laila e kau ana i kahi kahua paʻa no kāna noi ʻana ma nā ʻoihana he nui. I. Ka Mana Palena ʻole ma ke Kahua Ola Kino Ma ke kahua olakino, ʻike nui ʻia nā manaʻolana noi o chitosan. Loaʻa iā ia ka biocompatibility maikaʻi loa a me ka biodegradability, ka mea e lilo ai ia i mea lapaʻau kūpono. 1. Manaʻolana Hou no ka Mālama ʻEha - Ma ke ʻano o ka ho'ōla ʻana i ka ʻeha, hōʻike ʻo chitosan i nā pono kūikawā. Hiki iā ia ke hana i kahi micro - environment e kūpono ana i ka neʻe ʻana o nā cell a me ka hoʻonui ʻana, e hoʻolalelale ana i ke kaʻina hana ho'ōla ʻeha. Eia kekahi, loaʻa iā chitosan kekahi hana antibacterial a hiki ke kāohi i ka ulu ʻana o nā bacteria maʻamau ma ka ʻeha, e like me Staphylococcus aureus a me Escherichia coli. I kēia manawa, ua komo kekahi mau ʻāpana ʻeha chitosan holomua i ke kahua hoʻāʻo lapaʻau a manaʻo ʻia e lawe mai i nā hopena lapaʻau maikaʻi aʻe i nā poʻe maʻi me nā ʻeha mau, nā kuni, a me nā mea ʻē aʻe. 2. Ka Hana Hou i nā ʻŌnaehana Hoʻouna Lāʻau Lapaʻau - Loaʻa iā Chitosan ka hiki nui i ke kahua o ka lawe ʻana i ka lāʻau. Hiki ke hana ʻia i nanoparticles a i ʻole microspheres e hoʻopuni i nā molekala lāʻau like ʻole. Hiki i kēia mau mea lawe chitosan ke pale i nā lāʻau mai ka hōʻino ʻia e nā enzymes i loko o ke kino a hiki ke hoʻokō i ka hoʻokuʻu ʻana o nā lāʻau i nā wahi physiological kikoʻī. He mea nui kēia no nā kahua e pono ai ka lawe pololei ʻana i ka lāʻau, e like me ka mālama ʻana i ka maʻi kanesa a me ka mālama ʻana i nā maʻi cardiovascular. No ka laʻana, i ka lawe ʻana i nā lāʻau anti-cancer, hiki i nā mea lawe nanoparticle chitosan ke lawe pololei i nā lāʻau i nā ʻiʻo tumor, e hoʻonui ana i ka nui o ka lāʻau ma kahi tumor me ka hoʻemi ʻana i nā hopena ʻaoʻao ma nā ʻiʻo maʻamau. II. He Hōkū Piʻi ma ka ʻOihana Meaʻai 1. Ka Mālama ʻana i ka Meaʻai a me ka Hoʻopili ʻana - I ka ʻoihana meaʻai, ke puka mai nei ka chitosan. Ma muli o kona mau waiwai antibacterial a me ka hiki ke hana i nā kiʻiʻoniʻoni ʻai, hiki ke hoʻohana ʻia no ka mālama ʻana i ka meaʻai a me ka hoʻopili ʻana. Hiki i nā kiʻiʻoniʻoni Chitosan ke pale pono i ka hoʻouka kaua ʻana o ka oxygen, ka makū, a me nā microorganisms, e hoʻolōʻihi ana i ke ola o ka papa o ka meaʻai. No ka laʻana, no nā huaʻai hou a me nā huahana ʻiʻo, hiki i ka hoʻohana ʻana i ka ʻōpala chitosan ke hōʻemi i ka pilikia o ka palaho a me ka hōʻino a hōʻemi i ka nalowale o ka meaʻai. 2. Nā Mea Hoʻohui Meaʻai Hana - Hiki ke hoʻohana ʻia ʻo Chitosan ma ke ʻano he mea hoʻohui meaʻai hana. Loaʻa iā ia nā hana o ka hoʻoponopono ʻana i nā lipids koko a me ka hoʻemi ʻana i ka cholesterol a manaʻo ʻia e hoʻomohala ʻia i loko o kahi ʻano meaʻai olakino hou. Ua hōʻike kekahi mau noiʻi hiki i ka chitosan ke hoʻopaʻa i nā momona a me ka cholesterol i loko o ka ʻōpū, e pale ana iā lākou mai ka omo ʻia e ke kino kanaka, no laila e pāʻani ana i kahi hana ikaika i ka pale ʻana i ke olakino cardiovascular. III. He Kōkua Kūpono ma ke kahua palekana kaiapuni 1. Ka mālama ʻana i ka wai ʻino - Ma ke ʻano o ka palekana kaiapuni, hōʻike ka chitosan i nā hiki kupaianaha i ka mālama ʻana i ka wai ʻino. Hiki iā ia ke adsorb i nā ions metala kaumaha e like me ke kēpau, mercury, a me ka cadmium i loko o ka wai ʻino a hiki ke wehe i nā mea haumia organik i loko o ka wai ʻino. Hoʻokumu ʻia ke kumumanaʻo adsorption ma ka pilina ma waena o nā hui hana e like me nā hui amino a me hydroxyl ma ka mole chitosan a me nā mea haumia. Me nā koi palekana kaiapuni e piʻi nui nei, manaʻo ʻia e hoʻolaha hou ʻia ka hoʻohana ʻana o chitosan i ka mālama ʻana i ka wai ʻino ʻoihana. 2. Hoʻomaikaʻi ʻana i ka Lepo - Loaʻa iā Chitosan kahi hopena hoʻomaikaʻi maikaʻi ma ka lepo. Hiki iā ia ke hoʻomaikaʻi i ka wai - a me ka - momona - ka paʻa ʻana o ka lepo, hoʻolaha i ka hana o nā microorganisms lepo, a hoʻomaikaʻi i ke ʻano o ka lepo. I kekahi hoʻoponopono ʻana i ka lepo haumia, hiki i ka chitosan ke hui pū me nā mea ʻino i loko o ka lepo, e hōʻemi ana i ko lākou bio - loaʻa, a laila e hoʻihoʻi i ka lepo i kahi kūlana olakino. ʻOiai he ākea loa nā manaʻolana noi o chitosan, ke kū nei nō ia i kekahi mau pilikia i kēia manawa. No ka laʻana, he kiʻekiʻe ke kumukūʻai unuhi o chitosan, a pono e hoʻonui hou ʻia ke kaʻina hana o kāna hana ʻoihana nui. Eia kekahi, i kekahi mau noi, pono e hoʻomaikaʻi hou ʻia ka paʻa o ka hana o chitosan. Eia naʻe, me ka hoʻomohala mau ʻana o ka ʻepekema a me ka ʻenehana a me ka noiʻi hohonu, nui nā ʻoihana noiʻi ʻepekema a me nā ʻoihana e ʻimi ikaika nei i ka hiki o chitosan. Ua ʻōlelo kekahi loea: "Ke manaʻoʻiʻo nei mākou i loko o nā makahiki e hiki mai ana, me nā holomua ʻenehana, e hoʻopili nui ʻia ka chitosan ma nā ʻano he nui, e lawe mai ana i nā loli nui i ke olakino kanaka, ka meaʻai, ke kaiapuni, a pēlā aku." ʻO Chitosan, me kona mau pono kūikawā i ka mālama ola kino, ka ʻoihana meaʻai, ka palekana o ke kaiapuni a me nā ʻano ʻē aʻe, he mea maoli nō ia he biomaterial me ka hiki ke hoʻomohala nui ʻia, a ua piha kona mau manaʻolana noi i nā hiki palena ʻole.
