The paper discusses the man's contribution to the formation of aerosol particles in manned enclosures. The data obtained in prolonged simulation studies suggest that man is the major source of aerosol contamination. The aerosol concentration and disperse composition are found to depend on the free volume per man. The paper presents for the first time the data on the rate of dust formation in manned enclosures.

A sampler was needed for a spatial and temporal study of microbial and chemical stratification in a large swine manure lagoon that was known to contain zoonotic bacteria. Conventional samplers were limited to collections of surface water samples near the bank or required a manned boat. A new sampler was developed to allow simultaneous collection of multiple samples at different depths, up to 2.

Sprague-Dawley rats were subjected to three 8-to-10 day space flights on the Space Shuttle. Housed in NASA's Animal Enclosure Modules, rats were flown to test the hypotheses that therapy with pegylated interleukin-2 or insulin-like growth factor-1 would ameliorate some of the effects of space flight on the immune system. As part of these experiments, we measured body and organ weights, blood cell differentials, plasma corticosterone, macrophage colony forming units, lymphocyte mitogenic, super-antigenic and interferon-gamma responses, bone marrow cell and peritoneal macrophage cytokine secretion and bone strength and mass.

Space flight produces changes in neuronal activity in the vestibular system. We studied the protein expression of the NMDA receptor subunit NR1 in the vestibular ganglia of rats exposed to microgravity for 17 days, beginning on postnatal day 8, as part of the NASA Neurolab mission. As a control, we studied the cochlear ganglia in the same way.

This portion of the study quantified the effects of a 12-day space shuttle mission (Space Transport System-108/UF-1) on body and lymphoid organ masses, activation marker expression, cytokine secretion, and erythrocyte and thrombocyte characteristics in C57BL/6 mice. Animals in flight (Flt group) had 10-12% lower body mass compared with ground controls housed either in animal enclosure modules or under standard vivarium conditions (P < 0.001) and the smallest thymus and spleen masses.

To study renal handling of urinary electrolytes from male Fisher 344 rats during spaceflight, waste pads were obtained from cages flown in space and from cages used for ground controls. Pads were obtained from cages in which animals were group-housed (n=6 animals/cage) (Animal Enclosure Module; AEM) for 12 days or individually housed (2 animals/divided cage) (Research Animal Holding Facility; RAHF) for 19 days. Pads were washed, and extracts analyzed for sodium, potassium, chloride, calcium, and creatinine concentrations.
