[Iyini i-Huperzine A]

I-Huperzia uhlobo lobulembu obumila eShayina. Ihlobene ne-club mosses (umndeni we-Lycopodiaceae) futhi yaziwa kwezinye izazi zezitshalo ngokuthi i-Lycopodium serratum. I-moss yonke elungisiwe yayisetshenziswa ngokwesiko. Amalungiselelo amakhambi esimanje asebenzisa kuphela i-alkaloid engayodwa eyaziwa ngokuthi i-huperzine A. I-Huperzine A iyi-alkaloid etholakala ku-huperzia okuye kwabikwa ukuthi ivimbela ukuwohloka kwe-acetylcholine, into ebalulekile edingwa isimiso sezinzwa ukuze sidlulisele ulwazi kusuka kungqamuzana ukuya kungqamuzana. Ucwaningo lwezilwane luphakamise ukuthi ikhono le-huperzine A lokulondoloza i-acetylcholine lingase libe likhulu kuneleminye imithi kadokotela. Ukulahlekelwa ukusebenza kwe-acetylcholine kuyisici esiyinhloko sokuphazamiseka okuningana kokusebenza kobuchopho, okuhlanganisa nesifo i-Alzheimer's. I-Huperzine A ingase futhi ibe nomthelela ovikelayo ezicutshini zobuchopho, iqhubeke yandise amandla ayo etiyetha okusiza ukwehlisa izimpawu zokuphazamiseka okuthile kobuchopho.

[Umsebenzi] Isetshenziswa kwezinye izindlela zokwelapha, i-huperzine A itholakale isebenza njenge-cholinesterase inhibitor, uhlobo lomuthi olusetshenziselwa ukuvimbela ukuwohloka kwe-acetylcholine (ikhemikhali ebalulekile ekufundeni nasekukhumbuleni).

Ayisetshenziswa nje kuphela njengokwelapha isifo i-Alzheimer's, i-huperzine A kuthiwa ithuthukisa ukufunda nenkumbulo futhi ivikele ekuwohlokeni komqondo okuhlobene neminyaka.

Ukwengeza, i-huperzine A ngezinye izikhathi isetshenziselwa ukuqinisa amandla, ukwandisa ukuphaphama, nokusiza ekwelapheni i-myasthenia gravis (isifo esizimele esithinta imisipha).

Ama-carbohydrate ayizingxenye zokudla ezibalulekile ezithinta ukunambitheka nokudla. Ukunqunywa kwezinhlobo namazinga ama-carbohydrates ekudleni kubalulekile ekuhlolweni kwamandla, ukulebula okunomsoco, ukulawulwa kwekhwalithi kanye nokuhlonza okungase kube khona ukuphinga. Le webinar izochaza izindlela zakamuva zechromatographic zokulinganisa okujwayelekile kwama-carbohydrates ekudleni okuhlukahlukene neziphuzo. Funda mayelana nokutholwa kwe-aerosol eshajiwe emhlabeni wonke kanye nokutholwa kwe-amperometric eshaya ngamandla ukuze uthole ukunqunywa okuqondile kwamacarbohydrate kumatrices ayinkimbinkimbi. Funda mayelana nezinzuzo zalezi zindlela ngaphezu kwezinye izindlela zokuhlaziya kanye nokuphuma okuthuthukisiwe nokukhetha lezi zindlela ezingakulethela ilebhu yakho.
