[Dab tsi yog Huperzine A]

Huperzia yog hom moss uas loj hlob hauv Suav teb. Nws muaj feem xyuam rau cov qws mosses (Lycopodiaceae tsev neeg) thiab paub txog qee cov botanists li Lycopodium serratum . Tag nrho cov moss npaj tau siv ib txwm siv. Kev npaj tshuaj ntsuab niaj hnub tsuas yog siv cov alkaloid cais hu ua huperzine A. Huperzine A yog alkaloid pom nyob rau hauv huperzia uas tau tshaj tawm los tiv thaiv kev tawg ntawm acetylcholine, ib yam khoom tseem ceeb uas xav tau los ntawm lub paj hlwb kom xa cov ntaub ntawv ntawm tes mus rau ntawm tes. Kev tshawb fawb tsiaj tau pom tias huperzine A lub peev xwm khaws cia acetylcholine yuav ntau dua li ntawm qee cov tshuaj. Kev poob ntawm acetylcholine muaj nuj nqi yog qhov tseem ceeb ntawm ntau yam kev ua haujlwm ntawm lub paj hlwb, suav nrog Alzheimer's disease. Huperzine A kuj tseem tuaj yeem tiv thaiv cov ntaub so ntswg ntawm lub hlwb, ntxiv dag zog rau nws txoj kev muaj peev xwm los pab txo cov tsos mob ntawm qee lub hlwb.

[Function] Siv lwm cov tshuaj, huperzine A tau pom tias ua raws li cholinesterase inhibitor, ib hom tshuaj siv los tiv thaiv kev tawg ntawm acetylcholine (ib yam tshuaj tseem ceeb rau kev kawm thiab kev nco).

Tsis tsuas yog siv los ua kev kho mob Alzheimer's tus kab mob, huperzine A kuj tau hais los txhim kho kev kawm thiab kev nco thiab tiv thaiv lub hnub nyoog ntsig txog kev txawj ntse poob.

Tsis tas li ntawd, huperzine A yog qee zaum siv los txhawb lub zog, nce kev ceeb toom, thiab pab kho myasthenia gravis (ib qho kab mob autoimmune uas cuam tshuam rau cov leeg).

Carbohydrates yog cov khoom noj tseem ceeb uas cuam tshuam rau saj thiab khoom noj khoom haus. Kev txiav txim siab ntawm hom thiab qib ntawm carbohydrates hauv cov zaub mov yog qhov tseem ceeb rau kev ntsuas lub zog, kev sau cov khoom noj khoom haus, kev tswj kom zoo thiab txhawm rau txheeb xyuas qhov ua tau deev. Qhov webinar no yuav piav qhia txog qhov tseeb chromatographic txoj hauv kev rau kev ntsuas niaj hnub ntawm carbohydrates hauv ntau yam khoom noj thiab dej haus. Kawm paub txog qhov kev kuaj pom aerosol thoob ntiaj teb thiab xaiv qhov ntsuas pulsed amperometric rau kev txiav txim ncaj qha ntawm carbohydrates hauv cov matrices nyuaj. Kawm paub txog qhov zoo ntawm cov txheej txheem no dua li lwm txoj hauv kev tshuaj ntsuam thiab kev txhim kho thiab kev xaiv cov txheej txheem no tuaj yeem coj mus rau koj qhov chaw kuaj mob.
