RESULTS After using EOW and glutaraldehyde to disinfect the gastroscope and enteroscope the former showed that its killing rate on commonly encountered pathogens for 1 min was 93.75-98.22%,for 3 min was 81.20-89.29%,and for 5 min was 100.00%;
Disinfect the seed 3 minutes before inoculation. The optimum culture medium was 1/2 MS and supplemented with sugar 30g/L and agar 6g/L,which pH was 5.8~6.2 and induce ratio was 76.7%.
The result showed that the optimum medium for callus was MS + 2,4-D 2 mg/l + 6-BA 0.5 mg/l + IBA 0.2 mg/l and when the explant was disinfected with 10% of 84 Disinfectant Liquid,it had a better result.
The concentration of disinfectant after storaging 14d on 54℃ was decreased,only loss 1.46%,the concentration loss of disinfectant on using endoscope 5,7,and 14d after disinfection was 2.64%,0.69% and 0.94%,respectively.
in subgroup D,it was 259±83.0,274 ±76.3,and 291±87.2,P>0.05. CONCLUSIONS The most effective method of controlling bacterial pulltion of sphygmomanometer sleeve is the ultraviolet ray plus AHD2000 disinfectant.
It was then found that ammonia nitrogen did not affect the change of genotoxicity during chlorine dioxide disinfection of wastewater, while it greatly affected the change of genotoxicity during chlorine disinfection of wastewater.
An atmospheric-pressure glow discharge fired over the surface of water, in which hydrogen peroxide is produced in an amount sufficient for water disinfection, was studied.
Such lamps can be used in polymer chemistry, biology, potable water purification systems, for the sterilization of medical instruments, and in micro- and quantum electronics.
Subsequently, the colonies were separately immersed in a 0.1% chlorothalonil solution for 0.5 min to disinfect all surviving conidia on the host integument from 1-12 h after exposure under temperature treatments of 15 and 20°C, respectively.
Failure to wash hands and disinfect equipment between patients, which has been commonly seen in studies of health care worker compliance with infection control measures, may explain much of the continuing spread.
It grew well in 95% alcohol disinfectant and was insensitive to 84 disinfectant fluids containing chlorine (1000 mg/L) and such disinfectants as ozone.
It was suggested that alcohol disinfectant fluid was easily contaminated by Bacillus amyloliquefacien, and the bacteria was resistant to disinfectant fluids such as alcohol and 84 disinfectants.
The present study reviews more than twenty years (1985-present) of published research on the development and application of analytical procedures for the determination of chlorine dioxide, a widely used disinfectant and bleaching agent.
