[Yintoni iHuperzine A]

IHuperzia luhlobo lobulembu obukhula eTshayina. Inxulumene nobulembu beeklabhu (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).
