(18) Thermal characteristics of the pinnae of the ears of New Zealand White rabbits (Oryctolagus cuniculus) were measured with an infrared imaging system, and vasomotor oscillations were observed to occur spontaneously in the pinnae of all rabbits at an ambient temperature of 20 degrees C. Measured fluctuations in surface temperature were used to characterize the observed vasomotor oscillations, whereas heat loss from the pinnae was calculated using the mean pinna temperatures.
(19) We refined the method by which neonatal mouse hearts are transplanted into pouches in the pinnae of ears of adult recipient mice and used cyclosporine treatment as an example of how this method might be generally applied to study the dose-response relationship of immunosuppressive drugs.

Example Sentences:
