细菌计数

METHODS: The 144 BALB/c male mice were abdominally irradiated with 1150 cGy 60Coγray in 1-3 h, and then they were injected intestinal RNA from normal rats on jejunum.

选用BALB/c雄性小鼠144只，用1150 cGy 60Coγ射线进行腹部一次照射，于照后1~3 h采用局部肠腔扩张注入法给小鼠空肠肠腔内注入正常大鼠小肠RNA，分别于照后1，3，5 d麻醉后解剖，取血，测定内毒素含量；取肠系膜淋巴结，测定细菌移位率；取空肠段，计数肠腺存活率。

METHODS: The concentration of ozone that was transmitted by ozone generator at different time was determined by using iodine titrimetric method. According to the bactericidal assay of quantitative vehicle, the bacteria on the ozonized vehicles and unozonized vehicles was washed, 50μl eluant was seeded on the TSA plates. The TSA plates were put into the anaerobiotic incubator (90% N2, 10% CO2, 37℃). After 24 to 48 hours, the CFU on the plate was counted.

用碘滴定法测定打开臭氧发生器不同机组及不同时间时的臭氧浓度，按载体定量杀菌试验，将经臭氧作用的载体与相同环境下未经臭氧作用的载体上的细菌洗下，各取洗脱液50μl，接种于TSA平板并置厌氧箱(90%N2， 10%CO2， 37℃)培养24~48h后，进行活菌菌落计数。

Vibrio parahaemolyticus 1211U was cultured in sterilized sea water by the process of filtration at 4 ℃;50-60 days later, plate count and most probable number showed that there were no culturable bacteria.

将副溶血弧菌菌株1211U培养于低温贫养条件下，以平板菌落计数法和最大近似数法检测可培养细菌数，50～60d后表明可培养数下降为零。

The level of ifn γ secreted from splenocytes of immunized mice after specific antigen stimulation was detected by a cytopathic effect reduction assay and the splenocytic proliferation of immunized mice in response to antigen restimulation was detected by mtt assay.

分离免疫小鼠的脾淋巴细胞，体外用抗原再刺激，mtt方法检测ifn γ产生水平和mtt法检测淋巴细胞增殖，并对脾脏细菌负荷计数。
