Ib ntawm cov loj txwv rau suav phaj txoj hauv kev yog qhov sib txawv me me suav tau (feem ntau suav tias yog 25-250 CFU cov kab mob ntawm a tus qauv petri phaj).
Hauv qhov no, tus qauv phaj suav ntsuas dab tsi?
Txheem Phaj Suav los yog Phaj Loop Suav (SPC lossis PLC) yog ntsuas ntawm tag nrho cov naj npawb ntawm cov kab mob aerobic hauv cov mis. Mastitic nyuj tso cov kab mob tuaj yeem ua rau siab suav . Kev txwv txwv rau SPC yog 100, 000 kab mob/ml ntawm mis.
Ib qho ntxiv, dab tsi yog qhov kom zoo dua ntawm tus qauv phaj suav? Txheem Phaj Suav (SPC) muaj txiaj ntsig los tshuaj xyuas cov txheej txheem tswj hwm thiab txiav txim siab cov peev txheej ntawm kev sib kis hauv lub tebchaws, tab sis tsis yog qhov ntsuas tseeb ntawm cov kab mob txaus ntshai tshwj xeeb hauv kev pub mis lossis tag nrho cov khoom noj zoo.
Hauv txoj kev no, dab tsi yog qhov suav suav phaj aerobic?
Nws tseem raug hu ua aerobic pawg suav , txuj suav phaj , Mesophilic suav lossis Tag Nrho Phaj Suav.
Cov lus 1 Cov khoom raug Suav Aerobic Phaj Suav (CFU/g)
| Khoom muag | Almonds |
|---|---|
| Aerobic Phaj Suav rau Gram | 3, 000 – 7, 000 |
| Khoom muag | Pasta |
| Aerobic Phaj Suav rau Gram | 1, 000 – 10, 000 |
Peb puas tuaj yeem suav tag nrho cov kab mob suav nrog cov phaj txheem?
Microbiologists siv txheej txheem hu ua ' txheem phaj suav 'los kwv yees cov pejxeem ntom ntom ntawm kab mob nyob rau hauv lub broth los ntawm plating ib qho me me thiab dilute feem ntawm cov qauv thiab suav tus naj npawb ntawm kab mob cov cheeb tsam. Qhov no phaj yuav suav tsis txheeb thiab peb ua tau tsis siv nws kwv yees kab mob xov tooj ntawm tes.

Qhov twg ntawm cov hauv qab no yog piv txwv ntawm cov txheej txheem kev cia siab?
Cov txheej txheem kev cia siab yog cov txheej txheem uas tseem ceeb rau kev txhim kho thiab tshwm sim thoob plaws ib puag ncig. Qee qhov piv txwv ntawm cov txheej txheem kev cia siab yog lus, khoom noj khoom haus, thiab kev hlub. Cov txheej txheem kev paub dhau los yog cov txheej txheem uas tshwm sim nyob ntawm tus neeg ib puag ncig
Dab tsi yog cov txheej txheem txheej txheem ntawm cov pob txha ua los ntawm?
Cov txheej txheem sab nraud, uas yog ua los ntawm cov organic matrix (30%) muaj cov proteoglycans (tab sis tsawg dua pob txha mos), glycosaminoglycans, glycoproteins, osteonectin (thauj cov pob txha pob txha mus rau collagen) thiab osteocalcin (calcium khi protein)
Qhov sib txawv ntawm kev txwv thiab txwv tsis pub cov tub rog tshaj tawm yog dab tsi?
Ib tus neeg raug tsim txom tuaj yeem xaiv los hloov Daim Ntawv Ceeb Toom Txwv rau Tsis Pub Txwv txhua lub sijhawm. Txawm li cas los xij, thaum ua Daim Ntawv Ceeb Toom Txwv Tsis Pub Leej Twg Ua, qhov txwv txwv tsis muaj ntxiv lawm. Rau Daim Ntawv Ceeb Toom Tsis Pub Txwv - Cov neeg raug tsim txom tuaj yeem nthuav tawm kev yuam deev rau cov neeg no:
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Cov kauj ruam hauv cov txheej txheem txheej txheem txheej txheem mob yog dab tsi?
Cov ntsiab lus hauv cov txheej txheem no (8) ua kom cov vascular endothelium. vasodilation. ua npaws ntau lawm. tsiv teb tsaws ntawm cov kab mob tiv thaiv kab mob hlwb mus rau thaj chaw. ua kom thiab cytokine tso tawm los ntawm neutrophils. phagocytosis thiab cov hau kev ntawm kev puas tsuaj. tus mob theem teb. clotting cascade
