The surface area of the air/liquid interface in the lungs is substantial, so deposited doses of aerosol medicines per interface surface area when administered via the inhalation route is always quite low. However, in most in vitro systems used for dissolution testing of dry powder inhalables, the dose per surface area is generally much higher. The aim of this study was to investigate in one in vitro lung dissolution system, the DissolvIt, the manner in which the deposited dose per test surface area of drug particles influences the simulated dissolution- and absorption rate...

BACKGROUND: Singular traumatic insults, such as bone fracture, typically initiate an appropriate immune response necessary to restore the host to pre-insult homeostasis with limited damage to self. However, multiple concurrent insults, such as a combination of fracture, blunt force trauma, and burns (polytrauma), are clinically perceived to result in abnormal immune response leading to inadequate healing and resolution. To investigate this phenomenon, we created a model rat model of polytrauma...
