A: Qhov ncauj polio tshuaj tiv thaiv (OPV) muaj ib qho attenuated ( tsis muaj zog ) tshuaj tiv thaiv - kab mob vais lav , qhib kev tiv thaiv kev tiv thaiv kab mob hauv lub cev . Thaum tus menyuam tau txhaj tshuaj tiv thaiv kab mob OPV, tus tshuaj tiv thaiv tsis muaj zog - tus kab mob replicates nyob rau hauv cov hnyuv rau lub sijhawm tsawg, yog li tsim kev tiv thaiv los ntawm kev tsim cov tshuaj tiv thaiv.
Khaws qhov no rau hauv kev xav, cov tshuaj tiv thaiv twg muaj cov kab mob muaj sia nyob?
Tam sim no muaj nyob attenuated cov tshuaj tiv thaiv kab mob qhua pias, qhua pias, rubella , tshuaj tiv thaiv, varicella , zoster (uas muaj tus kab mob zoo ib yam li varicella tshuaj tiv thaiv tab sis ntau dua), ua npaws daj, rotavirus, thiab khaub thuas (intranasal).
Ib yam li ntawd, cov kab mob ua rau cov tshuaj tiv thaiv tsis muaj zog li cas? Muaj plaub txoj kev uas kab mob thiab cov kab mob yog qaug zog ua cov tshuaj tiv thaiv kab mob : Change cov kab mob vais lav blueprint (los yog noob) kom lub kab mob vais lav replicates tsis zoo. Nov yog li cas tus mob qhua pias, mumps, rubella, thiab varicella cov tshuaj tiv thaiv kab mob ua.
Hais txog qhov no, qhov twg ntawm cov tshuaj tiv thaiv hauv qab no muaj cov kab mob tua?
Hom suav nrog:
- Viral: tshuaj tiv thaiv kab mob polio (tshuaj tiv thaiv Salk) thiab tshuaj tiv thaiv khaub thuas.
- Cov kab mob: tshuaj tiv thaiv kab mob typhoid, tshuaj tiv thaiv kab mob cholera, tshuaj tiv thaiv kab mob plague, thiab tshuaj tiv thaiv kab mob pertussis.
Lawv ua li cas thiaj txo tau tus kab mob?
Nyob rau hauv ib txo qis tshuaj tiv thaiv, nyob kab mob vais lav hais nrog virulence tsawg heev yog tswj hwm. Lawv yuav rov tsim dua, tab sis qeeb heev. Cov tshuaj tiv thaiv no yog tsim los ntawm kev loj hlob kab mob vais lav hauv cov kab lis kev cai kab mob uas yuav xaiv rau cov kab mob sib kis tsawg dua, lossis los ntawm kev hloov pauv los yog lub hom phiaj tshem tawm hauv cov noob xav tau rau virulence.

Qhov twg ntawm cov tshuaj tiv thaiv hauv qab no yog siv rau kev txhaj tshuaj tiv thaiv kab mob?
Passive Immunization DISEASE NAME OF MATERIAL Cytomegalovirus Cytomegalovirus immun globulin, txhaj tshuaj tiv thaiv kab mob Diphtheria Diphtheria antitoxin, equine Rabies Rabies tiv thaiv globulin, tib neeg Measles Immune globulin, tib neeg
Cov ntsiav tshuaj daim ntawv twg muaj cov txheej tshwj xeeb uas tiv thaiv lub plab acid thiab ua rau cov tshuaj yaj hauv cov hnyuv?
Cov txheej txheej enteric yog cov txheej txheem polymer siv rau ntawm cov tshuaj hauv qhov ncauj uas tiv thaiv nws txoj kev tawg lossis tsis tawg hauv ib puag ncig lub plab
Hom cell twg hauv lub cev tiv thaiv kab mob tsim cov tshuaj tiv thaiv?
Lymphocytes yog ib hom tseem ceeb ntawm lub cev tiv thaiv kab mob. Lymphocytes feem ntau muab faib ua B thiab T hlwb. B lymphocytes tsim cov tshuaj tiv thaiv - cov protein (gamma globulins) uas lees paub cov tshuaj txawv teb chaws (antigen) thiab muab lawv tus kheej rau lawv
Cov tshuaj twg uas ua rau lub hauv nruab nrab lub paj hlwb yog Schedule II cov tshuaj thiab tsis tuaj yeem rov ua dua?
Barbiturates yog cov tshuaj tau los ntawm barbituric acid thiab ua raws li sedative lossis hypnotic. Cov tshuaj yuav tau sau los ntawm tus kws kho mob, tab sis yuav tsis muab rov qab. Qee qhov piv txwv ntawm Schedule II tshuaj yog morphine, codeine, fentanyl, meperidine (Demerol), hydromorphone (Dlaudid) thiab oxycodone
Puas yog kev tsim cov tshuaj tiv thaiv kab mob tsis yog lub cev tiv thaiv?
Kev tiv thaiv tshwj xeeb suav nrog teeb meem anatomic, inhibitors, phagocytosis, ua npaws, mob, thiab IFN. Cov kev tiv thaiv tshwj xeeb muaj xws li tshuaj tiv thaiv kab mob thiab kev tiv thaiv kab mob ntawm tes
