Studies of the Nasal Mucosa (COS 1129-8)
Principal Investigator
Research Area:
Radiation biology
Species Studied
Scientific Name: Rattus norvegicus Species: Rat Strain: Wistar


The basis for the present study was to determine if the lesions that were seen in the olfactory, but not respiratory, nasal mucosa of rodents in the experiment flown onboard Apollo-17 would be repeated. A further rationale involved the fact that the olfactory sense in rodents influences mating behavior. Thus, should these lesions develop during flight, with presumably impaired olfactory sense, they might be a contributing cause of the failure to mate seen in the rat ontogenesis experiment, should that indeed have been the case.
