 note = {Formaldehyde cabinets at ambient temperature have been used to sterilize heat-sensitive operating instruments in our operating rooms. The instruments were placed in formaldehyde cabinets with a capacity of 0.4 m^3 either wrapped in linen cloth or not wrapped. To generate the formaldehyde gas, 240g of formaldehyde-adsorbed plaster was deposited in the bottom of the cabinet. The efficiency of the sterilizing process was periodically examined using the spores of B. subtilis and B. stearothermophilus. During the past four years and two months, a total of 224 tests were performed, and 58 tests (25.9%) showed positive bacterial growth. Of 63 tests performed in the year of 1978 and 1979, no positive bacterial growth was observed at the exposure time of over 97 hrs. However, in January of 1980, the exchange interval of formaldehyde-adsorbed plaster was shortened from 4 to 2 weeks; thereafter, among 161 tests no bacterial growth was observed at the exposure time of over 73 hrs.},
