Comparative Histology Of The Respiratory Tract Of Normal Peromyscus Floridanus And P. Gossypinus And Effects Of Exposure To Solid Rocket Motor Fuel Exhaust On P. Gossypinus, Terry Lee Bitner
Retrospective Theses and Dissertations
Microscopic examination of the tracheal dimensions of normal Florida mice (Peromyscus floridanus) and cotton mice (P. gossypinus) showed no significant differences between the two species, but external examination showed the tracheal length of the Florida mouse to be longer than that of the cotton mouse. Microscopic examination of the intrapulmonary apparatus (bronchioles, alveolar ducts, atria, and alveoli) of normal Florida and cotton mice showed no significant differences in measurements between the two species. Cotton mice were exposed to exhaust gases produced by the burning of solid rocket motor (SRM) fuel. Mice exposed once for a duration of 10 min demonstrated …

Some Effects Of Solid Rocket Motor Fuel Exhausts On Avian Embryos, Lindsey Elliott Deguehery
Retrospective Theses and Dissertations
Fertile White Leghorn (Gallus gallus) and Bobwhite Quail (Colinus virginianus) were subjected to 15 min exposures produced by burning solid rocket motor (SRM) fuel. Comparative mortality data were collected. Chicken eggs were further used to study the effects of exposure on water relations and blood gas parameters. Chicken embryos exposed once on day 19 or incubation demonstrated and LD50 of 204 ppm; the LD50 for quail embryos was 175 ppm. When mortality was regressed on the final exposure concentration, chicken and quail embryos exposed on days 12 and 19 showed LD50's of 127 and 86 ppm respectively, and embryos exposed …
