1. Ua hōʻike ʻia ʻo Histamine Dihydrochloride e hoʻāla i ka nitric oxide synthetase a hoʻopaʻa a hoʻopaʻa i ka hana o nā ʻano oxygen reactive (ROS).ʻO ka pale ʻana i ka ROS e Histamine Dihydrochloride e ʻae i ka hoʻōla ʻana o nā pūnae T a me nā pūnaewele NK e IL-2.I loko o kahi hoʻohālike ʻiole, ua kāohi ka histamine dihydrochloride i ka ROS i hana ʻia e nā pūnaewele Kupffer ma o ka H2 histamine receptor.He vasodilator ikaika a me ka agonist receptor histamine endogenous.
2. ʻO Histamine Dihydrochloride (inoa kālepa Ceplene) he paʻakai ia o Histamine i hoʻohana ʻia ma ke ʻano he lāʻau lapaʻau no ka pale ʻana i ka hoʻi hou ʻana o nā maʻi i loaʻa i ka maʻi leukemia myeloid acute (AML).
He mea hoʻoikaika ikaika ia i ʻae ʻia e FDA no ka hoʻohana analgesic topical a loaʻa i nā huahana e like me Australian Dream Cream, i hoʻohana ʻia no ka hoʻomaha iki ʻana o nā ʻeha liʻiliʻi a me nā ʻeha o nā ʻiʻo a me nā hono e pili ana me ka maʻi o ka maʻi o ka maʻi, ka ʻeha hope, nā ʻeha, nā ʻeha, a nā ʻāʻī.
3. Hoʻohana ʻia ka Histamine Dihydrochloride no ke kala mau ʻana a me ka pale ʻana i ka hoʻi hou ʻana i nā poʻe maʻi me ka maʻi leukemia myeloid acute (AML) ma hope o ka hoʻomaʻamaʻa kala ʻana.Hoʻemi ka lāʻau lapaʻau i ka hana ʻana o nā pūʻulu oxygen e nā autophagocytes, kāohi i ka nicotinamide adenine dichemicalbo phosphate oxidase a pale i ka interleukin-2 mai ka hoʻoulu ʻana i nā pūnaewele NK a me nā cell T.Ua ʻae ʻia ʻo Histamine Dihydrochloride injection ma ke kumu o kona kala piha ʻana i ka hui pū ʻana me interleukin-2 i hōʻemi nui i ka hoʻihoʻi ʻana i nā maʻi AML.
