Lesi siphetho senziwe ngodokotela baseMelika abaye babona ukuthi kungakapheli iminyaka emithathu kwethulwe umuthi wokugomela isifo sofuba owaziwayo ezigulini ezinesifo sikashukela sohlobo 1, amazinga eglucose egazi acishe ajwayelekile futhi ahlala kulelo zinga iminyaka emihlanu ezayo.
Abaphenyi baphakamise ukuthi umuthi wokugomela we-BCG (okwalandela i-BCG) wenza umzimba uhlanganise izinto ezivimba amasosha omzimba ukuhlasela izicubu zomzimba. Futhi isifo sikashukela sohlobo 1 sitholakala ngokunembile lapho umzimba uqala ukuhlasela ama-pancreas awo, ukuwuvikela ekukhiqizeni i-insulin. I-BCG ingasheshisa ukuguqulwa kwe-glucose ibe amandla ngamaseli, ngaleyo ndlela inciphise inani layo egazini. Ucwaningo lwamagundane lukhombisa ukuthi kungenzeka ukuthi le ndlela yokunciphisa amazinga kashukela nayo ingasetshenziselwa isifo sikashukela sohlobo 2.
I-BCG umuthi wokugomela isifo sofuba owenziwe ngohlobo lwe-bacillus ephila buthaka (Mycobacterium bovis), elahlekelwe yi-virulence yayo kubantu, njengoba ikhule ngokukhethekile endaweni yokufakelwa. E-Russia, kwenziwa kuzo zonke izinsana ngaphandle kokuhluleka (lapho kungekho khona ukungqubuzana) kusukela ekuqaleni kweminyaka engama-60s yekhulu lokugcina ngokuzalwa futhi, futhi, eneminyaka engu-7 ubudala. E-USA naseGreat Britain, lo mgomo unikezwa kuphela abantu abasengozini.
Ucwaningo esibhedlela iMassachusetts General Hospital luhlale iminyaka engaphezu kwengu-8. Kuhanjelwe abantu abangama-52 abanesifo sikashukela sohlobo 1. Lababantu bathole imijovo emibili yokugoma ye-BCG ngokuhamba kwamaviki ama-4. Ngemuva kwalokho, bonke ababambe iqhaza kulolo hlolo bahlola izinga le-glucose egazini. Kuyo yonke iminyaka emi-3, amazinga kashukela kubantu abanesifo sikashukela sohlobo loku-1 acishe alingane nalawo abantu abanempilo futhi azinza kuleli zinga iminyaka emi-5. Izinga le-hemoglobin ye-glycated kubo lifinyelele ku-6,65%, kanti inani lokubhula lokuxilongwa lokuxilongwa kohlobo lwesifo sikashukela esingu-1,5 liyi-6.5%.
Umlobi walolu cwaningo, uDkt Denise Faustman, uthi: "Sithole isiqiniseko sokuthi ukusebenzisa umuthi wokugomela ophephile kunganciphisa ushukela wegazi njalo kufinyelele kumazinga ajwayelekile ngisho nakubantu asebegule iminyaka eminingi. Manje sesiyayiqonda kahle indlela esetshenziswa umuthi wokugomela i-BCG ushintsho oluzuzisa i-immune system bese lwehlisa ushukela wegazi ngohlobo 1 sikashukela. "
Kuze kube manje, inani elincane lababambe iqhaza kulolu cwaningo alusivumeli ukuthi sifinyelele eziphethweni zomhlaba wonke futhi sakhe amaprotocol amasha ekwelapheni isifo sikashukela, noma kunjalo, izifundo ngokungangabazeki zizoqhubeka, futhi sizolindela imiphumela yazo.
