[Yintoni iHuperzine A]

IHuperzia luhlobo lobulembu obukhula eTshayina. Inxulumene nobulembu beklabhu (usapho lweLycopodiaceae) kwaye yaziwa kwezinye iingcali ngezityalo njengeLycopodium serratum. I-moss yonke elungisiweyo yayisetyenziswe ngokwesiko. Amalungiselelo amayeza anamhlanje asebenzisa kuphela i-alkaloid ekwanti eyaziwa ngokuba yi-huperzine A. I-Huperzine A yi-alkaloid efumaneka kwi-huperzia eye yaxelwa ukunqanda ukuchithwa kwe-acetylcholine, into ebalulekileyo efunekayo yinkqubo ye-nervous yokuhambisa ulwazi kwiseli ukuya kwiseli. Uphando lwezilwanyana lucebise ukuba amandla e-huperzine A okugcina i-acetylcholine inokuba nkulu kuneyamanye amayeza kagqirha. Ukulahlekelwa ngumsebenzi we-acetylcholine luphawu oluphambili lweengxaki ezininzi zokusebenza kwengqondo, kuquka nesifo se-Alzheimer. I-Huperzine A inokuba nefuthe elikhuselayo kwizicubu zobuchopho, inyuse ngakumbi amandla ayo okucinga ukunceda ukunciphisa iimpawu zokuphazamiseka kwengqondo.

[Umsebenzi] Isetyenziswe kunyango olulolunye, i-huperzine A ifunyenwe isebenza njenge-cholinesterase inhibitor, uhlobo lweyeza elisetyenziselwa ukuthintela ukuchithwa kwe-acetylcholine (ikhemikhali ebalulekileyo yokufunda kunye nememori).

Ayisetyenziswanga kuphela njengonyango lwe-Alzheimer's, i-huperzine A ikwatsho ukuba iphucule ukufunda kunye nenkumbulo kunye nokukhusela ekunciphiseni kwengqondo okunxulumene neminyaka.

Ukongezelela, i-huperzine A ngamanye amaxesha isetyenziselwa ukunyusa amandla, ukwandisa ukuphaphama, kunye nokunceda unyango lwe-myasthenia gravis (i-autoimmune disorder echaphazela imisipha).

Iikhabhohayidrethi zizinto ezibalulekileyo zokutya ezichaphazela incasa kunye nesondlo. Ukumiselwa kweentlobo kunye namanqanaba e-carbohydrates ekutyeni kubalulekile kuvavanyo lwamandla, ukuleyibhelishwa kwesondlo, ukulawula umgangatho kunye nokuchonga ukuphinga okunokwenzeka. Le webinar iya kuchaza iindlela zamva nje zechromatographic zomlinganiselo wesiqhelo weecarbohydrates kwiintlobo ngeentlobo zokutya kunye neziselo. Funda malunga nokufunyanwa kwe-aerosol ehlawuliswayo jikelele kunye nokuchongwa okukhethiweyo kwe-amperometric ye-pulsed ukumiselwa ngokuthe ngqo kwe-carbohydrates kwiimatriki ezinzima. Funda malunga noncedo lwezi ndlela ngaphezu kwezinye iindlela zohlalutyo kunye nokuphuculwa kwe-throughput kunye nokukhetha ezi ndlela zingazisa kwilebhu yakho.
