Yonke imidumba, kuhlanganise nobhontshisi omnyama, iqukethe inhlanganisela ebizwa ngokuthi i-phytohemagglutinin, engaba yingozi kakhulu. Lena inkinga enkulu ngobhontshisi obomvu futhi, oqukethe inani eliphezulu lale nto kangangoba ubhontshisi oluhlaza noma ongaphekwa kahle ungaba yingozi uma udliwe.
Kodwa-ke, inani le-phytohemagglutinin kubhontshisi omnyama ngokuvamile liphansi kakhulu kunobhontshisi obomvu, futhi imibiko yobuthi ayizange ihlotshaniswe nale ngxenye.
Uma usenokungabaza mayelana ne-phytohemagglutinin, khona-ke izindaba ezinhle kuwe ukuthi ukupheka ngokucophelela kunciphisa inani le-toxin kubhontshisi.
Ubhontshisi omnyama udinga ukucwiliswa isikhathi eside (amahora ayi-12) nokuhlanjululwa. Lokhu kukodwa kususa ubuthi. Ngemuva kokucwilisa nokugeza, ulethe ubhontshisi emathunjini bese ususa igwebu. Ochwepheshe batusa ukubilisa ubhontshisi phezu kokushisa okuphezulu okungenani imizuzu eyi-10 ngaphambi kokuphuza. Akufanele upheke ubhontshisi omisiwe phezu kokushisa okuphansi, ngoba ngokwenza lokhu asibhubhisi, kodwa ukwandisa kuphela okuqukethwe kwe-phytohemagglutinin toxin.
Izinhlanganisela ezinobuthi ezifana ne-phytohemagglutinin, i-lectin, zikhona ezinhlotsheni eziningi ezivamile zemifino, kodwa ubhontshisi obomvu baningi kakhulu. Ubhontshisi omhlophe uqukethe ubuthi obuphindwe kathathu kunezinhlobo ezibomvu.
I-Phytohemagglutinin ingavalwa ngokubilisa ubhontshisi imizuzu eyishumi. Imizuzu eyishumi ku-100 ° yanele ukunciphisa ubuthi, kodwa akwanele ukupheka ubhontshisi. Ubhontshisi owomile kufanele uqale ugcinwe emanzini okungenani amahora ama-5, okumele akhishwe.
Uma ubhontshisi uphekwe ngaphansi kokubilisa (futhi ngaphandle kokubiliswa kwangaphambili), ekushiseni okuphansi, umphumela onobuthi we-hemagglutinin uyakhula: ubhontshisi ophekwe ku-80 °C kwaziwa ukuthi unobuthi obuphindwe kahlanu kunobhontshisi oluhlaza. Amacala obuthi ahlotshaniswa nokupheka ubhontshisi phezu kokushisa okuphansi.
Izimpawu eziyinhloko zobuthi be-phytohemagglutinin isicanucanu, ukuhlanza, nesifo sohudo. Ziqala ukubonakala ihora elilodwa noma amathathu ngemva kokuphuza ubhontshisi ophekwe ngendlela engafanele, futhi izimpawu ngokuvamile ziphela emahoreni ambalwa. Ukudla ubhontshisi obune noma obuhlanu obuluhlaza noma obungacwilisiwe futhi obungaphekiwe kungabangela izimpawu.
Ubhontshisi waziwa ngokuqukethwe kwawo okuphezulu kwama-purines, agaywa abe yi-uric acid. I-Uric acid ayiyona i-toxin ngayinye, kodwa ingaba nomthelela ekwakhiweni noma ekubhebhethekeni kwe-gout. Ngenxa yalesi sizathu, abantu abane-gout bavame ukululekwa ukuthi banciphise ukudla kwabo ubhontshisi.
Kuhle kakhulu ukupheka wonke ubhontshisi esitokisini esicindezelayo esigcina izinga lokushisa elingaphezu kwendawo yokubilisa ngesikhathi sokupheka nangesikhathi sokukhululeka kwengcindezi. Iphinde inciphise kakhulu isikhathi sokupheka.
