Ukuhlolwa kwe-Lactic acid

I-Lactic acid ikhiqizwa kakhulu kumaseli emisipha namaseli abomvu egazi. Yakha lapho umzimba wephula ama-carbohydrate ukuze uwasebenzisele amandla lapho amazinga e-oxygen ephansi. Izikhathi lapho ileveli yomoya-mpilo yomzimba wakho ingehla ifaka phakathi:

• Ngesikhathi sokuzivocavoca okukhulu
• Lapho unesifo noma isifo

Ukuhlolwa kungenziwa ukukala inani le-lactic acid egazini.

Kudingeka isampula yegazi. Isikhathi esiningi igazi likhishwa emthanjeni ongaphakathi endololwaneni noma ngemuva kwesandla.

UNGazivocavoci amahora amaningi ngaphambi kokuhlolwa. Ukuzivocavoca umzimba kungadala ukwanda kwesikhashana emazingeni e-lactic acid.

Ungase uzwe ubuhlungu obuncane noma isitinyela lapho kufakwa inaliti. Ungase futhi uzizwe ushaywa yisiza ngemuva kokukhishwa kwegazi.

Lokhu kuhlolwa kuvame ukwenziwa ukuthola i-lactic acidosis.

Imiphumela ejwayelekile isukela kumamiligram ayi-4.5 kuye kwayi-19.8 nge-deciliter ngayinye (mg / dL) (0.5 kuye ku-2.2 millimoles ngelitha ngalinye [mmol / L]).

Ububanzi bamanani ajwayelekile bungahluka kancane phakathi kwamalabhorethri ahlukene. Khuluma nomhlinzeki wakho mayelana nencazelo yemiphumela yakho ethile yokuhlolwa.

Izibonelo ezingenhla zibonisa izilinganiso ezivamile zemiphumela yalezi zivivinyo. Amanye ama-laboratories asebenzisa izilinganiso ezahlukahlukene noma angahlola izinhlobo ezahlukene.

Imiphumela engajwayelekile isho ukuthi izicubu zomzimba azitholi i-oxygen eyanele.

Izimo ezingakhuphula amazinga e-lactic acid zifaka:

• Ukwehluleka kwenhliziyo
• Isifo sesibindi
• Isifo samaphaphu
• Alikho igazi elanele eliqukethe i-oxygen elifinyelela endaweni ethile yomzimba
• Ukutheleleka okukhulu okuthinta umzimba wonke (sepsis)
• Amazinga aphansi kakhulu e-oxygen egazini (i-hypoxia)

Ukugoqa isibhakela noma ukufaka ibhande le-elastic isikhathi eside ngenkathi udonswa igazi kungaholela ekukhuleni okungamanga ezingeni le-lactic acid.
