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%;
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.
The antibacterial ability of copper has a potential application in the field of disinfection, food packaging and piping of drinking water.
The cross-infection was severe and strict methods of disinfection and sterilization should be implemented.
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.
Statistical methods of miltifactorial experiment design have been applied to studying the disinfection of drinking water with ozone.
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.
Metal ions or metal ions in complexes or compounds have been used for centuries to disinfect fluids, solids and tissues.
It is demonstrated that chlorine added to disinfect tap water eliminates any possible residual tepraloxydim.
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.
A simple and inexpensive way to reduce nosocomial infections in ICUs is to ensure that staff disinfect their hands after dealing with a patient.
Characterization of Bacillus amyloliquefacien contaminating 75% alcohol disinfectant
The bacteria were found after being cultured in the clinically-used 75% alcohol disinfectant fluid.
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.
