[Hygienic evaluation of experimental samples of antimicrobial underwear containing hexachlorophene].

The hygienic examination of 12 samples of knitted underwear which contained hexachlorophene added during fiber formation allowed the selection of four types that can be used under poor sanitation conditions. Taking into consideration possible changes in the proportion of various micoorganisms during prolonged space flights, it is recommended to carry out a complex investigation in order to allow the use of the antimicrobial underwear by specific crewmembers during a certain period of time.
