Chloramphenicol yog dab tsi?
Chloramphenicol, tseem hu ua chlornitromycin, yog ib tug dav-spectrum, bacteriostatic tshuaj tua kab mob muab tau los ntawm Streptomyces venezuelae. Nws yog semisynthetic, broad-spectrum tshuaj tua kab mob muab tau los ntawm Streptomyces venequelae nrog feem ntau bacteriostatic kev ua.
Chemical Properties
Nws yog dawb los yog yellowish ntsuab koob zoo li muaju. Lub melting point yog 150.5-151.5 ℃ (149.7-150.7 ℃). Nyob rau hauv lub tshuab nqus tsev siab, nws tuaj yeem sublimated, me ntsis soluble hauv dej (2.5mg / ml ntawm 25 ℃), me ntsis soluble hauv propylene glycol (150.8mg / ml), soluble hauv methanol, ethanol, butanol, ethyl acetate, acetone, insoluble hauv ether, benzene, roj av ether, zaub roj. Saj yog iab heev.
Kev siv thiab kev ua haujlwm ntawm Chloramphenicol
Chloramphenicol yog bacteriostatic thiab broad-spectrum tshuaj tua kab mob tawm tsam cov kab mob gram-positive thiab gram-negative nrog rau rickettsia (ua rau pob zeb- roob pom kub taub hau) thiab chlamydia. Nws kuj tseem pom muaj txiaj ntsig tiv thaiv Haemophilus influenzae ua rau mob meningitis.
Chloramphenicol yog siv rau kev kho mob los ntawm kab mob typhoid bacillus, dysentery bacillus, Escherichia coli, bacillus, influenza thiab pneumococcal kab mob xws li brucellosis.
Chloramphenicol yog siv los kho cov kab mob los ntawm cov kab mob. Nws ua haujlwm los ntawm kev tua kab mob lossis tiv thaiv lawv txoj kev loj hlob.
Chloramphenicol yog siv los kho cov kab mob loj hauv ntau qhov chaw ntawm lub cev. Qee zaum nws tau muab nrog lwm cov tshuaj tua kab mob. Txawm li cas los xij, chloramphenicol yuav tsum tsis txhob siv rau kev mob khaub thuas, mob khaub thuas, lwm yam kab mob kis, mob caj pas lossis lwm yam kab mob me, lossis tiv thaiv kev kis kab mob.
Chloramphenicol yuav tsum tsuas yog siv rau cov kab mob loj uas lwm cov tshuaj tsis ua haujlwm. Cov tshuaj no yuav ua rau muaj kev phiv loj heev, suav nrog teeb meem ntshav thiab teeb meem qhov muag. Cov tsos mob ntawm cov ntshav muaj xws li tawv nqaij daj ntseg, mob caj pas thiab kub taub hau, los ntshav txawv txawv lossis nqaij tawv, thiab qaug zog lossis qaug zog.
